The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a dual-panel display panel according to an embodiment of the present invention.

The dual display panel includes: the display panel comprises a light control panel and a display panel which are arranged oppositely, wherein the light control panel is arranged on the light incident side of the display panel.

The display panel comprises a plurality of first gate lines 11 extending along a first direction and a plurality of first data lines 12 extending along a second direction, the extending directions of the first direction and the second direction are crossed, the first gate lines 11 and the first data lines 12 are crossed to define a plurality of sub-pixel units 13 arranged in an array, and sub-pixel electrodes 14 are arranged in the sub-pixel units 13.

The light control panel comprises a plurality of second gate lines 15 extending along the first direction and a plurality of second data lines 16 extending along the second direction, the second gate lines 15 and the second data lines 16 intersect to define a plurality of light control units 17 arranged in an array, a part of the light control units 17 comprise at least two sub-light control units 18, and sub-light control electrodes 19 are arranged in the sub-light control units 18.

Wherein the outer contour shapes of the sub-pixel electrode 14 and the sub-photo-control electrode 19 are different.

The region formed by the outer contour shape of the sub-pixel electrode can be understood as a region of a sub-pixel unit; similarly, the area formed by the external contour shape of the sub-light-controlling electrode can be understood as the area of the sub-light-controlling unit.

In this embodiment, as shown in fig. 1, the first direction is taken as a horizontal direction, and the second direction is taken as a vertical direction for example.

The display panel is divided into a plurality of sub-pixel units 13 arranged in an array by a first gate line 11 extending along a horizontal direction and a first data line 12 extending along a vertical direction, and further, referring to fig. 2, fig. 2 is a schematic structural diagram of a display panel according to an embodiment of the present invention. As shown in fig. 2, based on the sub-pixel unit 13 in the regular pattern area (e.g., the rectangular sub-pixel unit illustrated in fig. 2), one sub-pixel electrode 14 is disposed in one sub-pixel unit 13, and in order to increase the effective area of one sub-pixel unit 13 as much as possible, the coverage area of the sub-pixel electrode 14 occupies the area defined by the sub-pixel unit 13 as much as possible, that is, the shape of the outer contour of the sub-pixel electrode 14 is substantially similar to the shape defined by the sub-pixel unit 13.

The adjacent sub-pixel units 13 have a first light-shielding area a1 therebetween, the first light-shielding area a1 is parallel or perpendicular to the row of the sub-pixel units 13, and a plurality of equally spaced first light-shielding areas a1 form a first light-shielding area array, which is similar in periodicity at least in the row of the sub-pixel units 13.

The first gate line 11 and the first data line 12 are located within the first light-shielding area a 1.

As understood from the above description, the first light-shielding region a1 is arranged in a manner equivalent to defining the outer contour shape of the sub-pixel unit 13, and thus the outer contour shape of the sub-pixel electrode 14.

It should be noted that the sub-pixel unit 13 is a red sub-pixel unit, a green sub-pixel unit, or a blue sub-pixel unit, that is, what is called an RGB sub-pixel unit.

Alternatively, the sub-pixel unit 13 is a red sub-pixel unit, a green sub-pixel unit, a blue sub-pixel unit, or a white sub-pixel unit, that is, the RGBW sub-pixel unit is commonly referred to.

Based on this, in the course of the invention of the present application, the inventor found that, referring to fig. 3, fig. 3 is a schematic structural diagram of a light-controlling panel in the prior art, and a conventional light-controlling panel is also divided into a plurality of light-controlling units 17 arranged in an array by the second gate lines 15 extending along the horizontal direction and the second data lines 16 extending along the vertical direction. Furthermore, based on the light-controlling units 17 with regular pattern areas (such as the rectangular light-controlling unit illustrated in fig. 3), one light-controlling electrode 20 is disposed in one light-controlling unit 17, and in order to increase the effective area of one light-controlling unit 17 as much as possible, the coverage area of the light-controlling electrode 20 will occupy the area defined by the light-controlling unit 17 as much as possible, that is, the shape of the outer contour of the light-controlling electrode 20 will be substantially similar to the shape defined by the light-controlling unit 17, and in general, the shape defined by the light-controlling unit 17 is the same as the shape defined by the sub-pixel unit 13, that is, the light-controlling unit 17 is rectangular.

The second light-shielding regions a2 are disposed between adjacent light-controlling units 17, the second light-shielding regions a2 are parallel or perpendicular to the row direction of the light-controlling units 17, and a plurality of equally spaced second light-shielding regions a2 form a second light-shielding region array, which is similar to the second light-shielding region array at least periodically in the row direction of the light-controlling units 17.

The second gate line 15 and the second data line 16 are located within the second light-shielding area a 2.

As understood from the above description, the second light-shielding region a2 is arranged in a manner equivalent to defining the outer contour shape of the light-controlling unit 17, and thus the outer contour shape of the light-controlling electrode 20.

As can be seen from fig. 2 and 3, the second light-shielding region a2 and the first light-shielding region a1 are also similar in periodicity at least in the direction of the column of the sub-pixel units 13.

Then, when light passes through the display panel and the light control panel, an optical interference phenomenon is generated in the direction of the row of the sub-pixel units 13, so that black and white moire fringes appear in the display area of the dual-screen display panel, and the display effect of the conventional dual-screen display panel is reduced.

Therefore, referring to fig. 4, fig. 4 is a schematic structural diagram of a light control panel according to an embodiment of the present invention. The invention improves the light control panel, improves one light control electrode 20 in partial light control unit 17 of the light control panel into at least two sub-light control electrodes 19 with the external outline shape different from that of the sub-pixel electrode 14, namely indirectly changes the arrangement mode of the second light shielding area A2 by changing the external outline shape of the sub-light control electrodes 19, keeps the arrangement mode of the first light shielding area A1 unchanged, further disturbs the arrangement mode of the light shielding areas (the first light shielding area A1 and the second light shielding area A2) in the display panel and the light control panel, reduces the periodic similarity degree of the second light shielding area A2 and the first light shielding area A1 in the direction of the sub-pixel unit 13 column, further reduces the optical interference phenomenon generated in the direction of the sub-pixel unit 13 column when light passes through the display panel and the light control panel, and then the moire phenomenon of the double-screen display panel is greatly reduced.

Specifically, referring to fig. 5, fig. 5 is a schematic structural diagram of another light control panel according to an embodiment of the present invention.

The light control panel is divided into a plurality of light control units 17 arranged in an array by second gate lines 15 extending along the horizontal direction and second data lines 16 extending along the vertical direction, and one light control electrode 20 in part of the light control units 17 of the light control panel is modified into at least two sub-light control electrodes 19 with the external outline shape different from that of the sub-pixel electrodes 14, so that one light control unit 17 forms at least two sub-light control units 18 with the external outline shape different from that of the sub-pixel units 13.

Then, the third light-shielding regions A3 are located between two adjacent sub-light-controlling units 18, and only part of the third light-shielding regions A3 in the row direction of the sub-light-controlling units 18 is similar to the first light-shielding regions A1 in the display panel, the remaining portion of the third light-shielding region A3 is arranged differently from the first light-shielding region a1 in the display panel, further, the arrangement of the light-shielding regions (the first light-shielding region a1 and the third light-shielding region A3) in the display panel and the light-controlling panel is disturbed, so as to reduce the degree of the periodic similarity between the third light-shielding region A3 and the first light-shielding region a1 in the direction of the row of the sub-pixel units 13, and further reduce the light transmission through the display panel and the light-controlling panel, the optical interference phenomenon generated in the direction of the row of the sub-pixel units 13, and further the moire phenomenon of the double-screen display panel is greatly reduced.

Further, based on the above embodiment of the present invention, referring to fig. 6, fig. 6 is a schematic diagram of a sub-light control electrode according to an embodiment of the present invention.

The sub-photo-control electrode 19 includes: a vertical main line 191, a bent main line 192, and a plurality of domain lines 193.

One end of each of the domain lines 193 is connected to the vertical trunk line 191, and the other end is connected to the bent trunk line 192;

wherein the vertical trunk region and the bent trunk region are black domain regions.

The black domain belongs to a part of the third light-shielding region a 3.

In this embodiment, since the extending direction of the vertical trunk lines 191 is perpendicular to the alignment direction (i.e. the horizontal direction), a transverse electric field is formed in the region where the vertical trunk lines 191 are located, so that the liquid crystal molecules in the region cannot be controlled to deflect, and light rays in the region cannot pass through, and thus the vertical trunk line region is a black domain region.

In addition, since the potential of the region where the bent main line 192 is located is disordered, a lateral electric field is finally formed, and the liquid crystal molecules in the region cannot be controlled to deflect, so that light in the region cannot pass through, the bent main line region is also a black domain region.

That is, the present application divides the light control electrode 20 with regular edge profile into two sub light control electrodes 19 with irregular edge profile by adopting black domain.

In general, the third light-shielding region a3 needs to be provided with a light-shielding matrix to divide the electrode region, but the black domain itself has a light-shielding function, so that in an embodiment of the present invention, the electrode region is divided by the black domain, and the light-shielding matrix process in the light-controlling panel can be omitted, i.e., the light-shielding matrix does not need to be provided on the light-controlling panel, thereby greatly reducing the cost of the dual-panel display panel and simplifying the manufacturing process.

It should be noted that the middle regions of the bent stems 192 at the right part in fig. 6 may also be connected together, and are illustrated in an exemplary manner in the embodiment of the present invention.

Further, based on the above embodiments of the present invention, referring to fig. 7, fig. 7 is a schematic view of a connection relationship between sub-light-controlling electrodes according to an embodiment of the present invention.

The vertical trunk line 191 is connected to one electrode terminal of the thin film transistor T in the array substrate.

In this embodiment, the second gate line 15 is connected to the gate of the thin film transistor T, the second data line 16 is connected to one electrode terminal of the thin film transistor T, and the vertical trunk line 191 of the sub-light-controlling electrode 19 is connected to the other electrode terminal of the thin film transistor T.

Accordingly, by connecting the vertical trunk line 191 to one electrode terminal of the thin film transistor T, the connection of the other electrode terminal of the thin film transistor T to the second data line 16 can be facilitated, and the wiring manner of the light control panel can be simplified.

Moreover, only by connecting one electrode end of the thin film transistor T with the vertical main line 191, a signal can be transmitted to the plurality of domain lines 192 and the bent main line 192 through the vertical main line 191, so that the signal transmission is faster and more uniform, the electric field generated by the subsequent sub-light control electrode 19 and the common electrode to drive the liquid crystal molecules to deflect is more uniform and stable, and the response speed is also improved.

Further, based on the above embodiments of the present invention, referring to fig. 8, fig. 8 is a schematic shape diagram of a sub-light-controlling electrode according to an embodiment of the present invention.

The bent stem 192 includes at least one bend angle β.

In this embodiment, as shown in FIG. 8, the bent trunk line 192 includes a bent angle β, so as to divide a light-controlling electrode 20 having a rectangular edge profile into two sub-light-controlling electrodes 19 having irregular edge profile.

In this embodiment, by providing the bending main line 192 having at least one bending angle β, under the condition that the number and size of the bending angles β can be changed, the edge profile of the sub-light-controlling electrodes 19 is further irregular, and the arrangement of the light-shielding regions (the first light-shielding region a1 and the third light-shielding region A3) in the display panel and the light-controlling panel is further disturbed, so as to reduce the degree of the periodic similarity between the third light-shielding region A3 and the first light-shielding region a1 in the direction of the row of the sub-pixel units 13, further reduce the optical interference phenomenon generated in the direction of the row of the sub-pixel units when light passes through the display panel and the light-controlling panel, and further greatly reduce the moire phenomenon of the dual-panel.

Further, based on the above-mentioned embodiment of the present invention, referring to fig. 9, fig. 9 is a schematic shape diagram of another sub-light-control electrode provided in the embodiment of the present invention.

The bending stem 192 includes a plurality of bending angles β, and the light-controlling electrode 20 having a rectangular edge profile can be divided into two sub-light-controlling electrodes 19 having more irregular edge profile by setting the plurality of bending angles β, so as to further increase the difference between the edge profiles of the sub-light-controlling electrodes 19 and the sub-pixel electrodes 14, and reduce the moire phenomenon to the maximum extent.

In the drawings, β represents only the position of the bending angle, and the plurality of bending angles may be the same or different in size, and may be determined according to the actual situation.

Further, based on the above-mentioned embodiment of the present invention, referring to fig. 10, fig. 10 is a schematic shape diagram of another sub-light-controlling electrode according to the embodiment of the present invention.

The bending angle beta is less than or equal to 180 deg.

In this embodiment, as shown in fig. 8 and 9, the angle of the bending angle β is less than 180 °, and when the angle of the bending angle β is equal to 180 °, as shown in fig. 10, the extending direction of the bending main line 192 and the extending direction of the vertical main line 191 need to intersect, for example, the shape of the sub-light control electrode 19 is triangular.

By setting the bending angle of the bent main line 192 to 180 ° and making the extending direction of the bent main line 192 intersect with the extending direction of the vertical main line 191, so that the light control electrode 20 with a rectangular edge profile is divided into two sub light control electrodes 19 with more irregular edge profile, the electrode manufacturing process can be simplified in case the electrode profile can be changed.

Further, according to the above-mentioned embodiment of the present invention, as shown in fig. 7, in one of the control units, the bent trunk lines in two of the sub-control photo-electrodes 19 are adjacently disposed, and there is a gap.

In this embodiment, in order to avoid the electric field interference in the two sub-light-controlling electrodes 19, a gap is required between the bent main lines 192 of the two sub-light-controlling electrodes 19 in one light-controlling unit 17.

Furthermore, in order to increase the effective area of the electrode as much as possible, the gap is reduced as much as possible while satisfying the condition that the electric field is not disturbed.

Further, according to the above-mentioned embodiment of the present invention, as shown in fig. 7, in one light-controlling unit 17, the bending directions of the bending main lines 192 in two sub-light-controlling electrodes 19 are the same.

In this embodiment, by making the bending direction of the bent trunk line 192 the same, the electrode effective area in one light controlling unit 17 can be effectively increased.

Further, based on the above embodiments of the present invention, referring to fig. 11, fig. 11 is a schematic layout diagram of the sub-photo-control electrodes in the photo-control panel according to the embodiments of the present invention.

In the row direction of the array arrangement, the bending directions of the bending main lines 192 in the sub-light control electrodes 19 are different in two adjacent columns of the light control units 17.

In this embodiment, the regular arrangement of the sub-photo-control electrodes 19 in the photo-control panel is further disturbed by the different bending directions of the bending trunk lines 192 of the sub-photo-control electrodes 19 in the two adjacent columns of the photo-control units 17, and the arrangement of the light-shielding regions (the first light-shielding region a1 and the third light-shielding region A3) in the display panel and the photo-control panel is further disturbed, so as to reduce the periodic similarity of the third light-shielding region A3 and the first light-shielding region a1 in the direction of the column of the sub-pixel unit 13, and further reduce the optical interference phenomenon generated in the direction of the column of the sub-pixel unit when light passes through the display panel and the photo-control panel, thereby greatly reducing the moire phenomenon of the dual-panel. .

Further, based on the above-mentioned embodiment of the present invention, referring to fig. 12, fig. 12 is a schematic layout diagram of the sub-photo-control electrodes in another photo-control panel provided in the embodiment of the present invention.

In the column direction of the array arrangement, the bending directions of the bending main lines 192 in the sub light-controlling electrodes 19 are different in two adjacent rows of the light-controlling units 17.

In this embodiment, the regular arrangement of the sub-light-controlling electrodes 19 in the light-controlling panel is further disturbed by the different bending directions of the bending main lines 192 of the sub-light-controlling electrodes 19 in the two adjacent rows of the light-controlling units 17, and the arrangement of the light-shielding regions (the first light-shielding region a1 and the third light-shielding region A3) in the display panel and the light-controlling panel is further disturbed, so as to reduce the periodic similarity of the third light-shielding region A3 and the first light-shielding region a1 in the direction of the row of the sub-pixel units 13, further reduce the optical interference phenomenon generated in the direction of the row of the sub-pixel units when light passes through the display panel and the light-controlling panel, and further greatly reduce the moire phenomenon of the dual-panel display panel. .

Further, based on the above embodiment of the present invention, referring to fig. 13, fig. 13 is a schematic layout diagram of the sub-photo-control electrodes in the photo-control panel according to another embodiment of the present invention.

In the row direction of the array arrangement, the bending directions of the bending main lines 192 in the sub-light control electrodes 19 are different in two adjacent light control units 17.

In this embodiment, the regular arrangement of the sub-light-controlling electrodes 19 in the light-controlling panel is further disturbed by the different bending directions of the bending main lines 192 of the sub-light-controlling electrodes 19 in each row of the two adjacent light-controlling units 17, and the arrangement of the light-shielding regions (the first light-shielding region a1 and the third light-shielding region A3) in the light-controlling panel is further disturbed, so as to reduce the periodic similarity of the third light-shielding region A3 and the first light-shielding region a1 in the direction of the row of the sub-pixel units 13, further reduce the optical interference phenomenon generated in the direction of the row of the sub-pixel units when light passes through the display panel and the light-controlling panel, and further greatly reduce the moire phenomenon of the dual-panel. .

Further, based on the above embodiment of the present invention, referring to fig. 14, fig. 14 is a schematic layout diagram of a sub-photo-control electrode in another photo-control panel provided in an embodiment of the present invention.

In the column direction of the array arrangement, the bending direction of the bending trunk line 192 in the sub-light control electrode 19 is different in two adjacent light control units 17.

In this embodiment, the regular arrangement of the sub-light-control electrodes 19 in the light-control panel is further disturbed by the different bending directions of the bending main lines 192 of the sub-light-control electrodes 19 in the two adjacent light-control units 17 in each row, so as to disturb the arrangement of the light-shielding regions (the first light-shielding region and the third light-shielding region) in the display panel and the light-control panel, so as to reduce the periodic similarity of the third light-shielding region and the first light-shielding region in the direction of the sub-pixel unit row, further reduce the optical interference phenomenon generated in the direction of the sub-pixel unit row when light passes through the display panel and the light-control panel, and further reduce the moire phenomenon of the dual-panel display panel to a great extent. .

Further, based on the above embodiment of the present invention, the area of the sub-light control unit 19 is not smaller than the area of the sub-pixel unit 13.

In this embodiment, when the area of the sub-light control unit 19 is not smaller than the area of the sub-pixel unit 13 as much as possible, for example, when the area of the sub-light control unit 19 is equal to the area of the sub-pixel unit 13, light control for each sub-pixel unit 13 is realized, that is, finer backlight control can be realized to realize better display effect.

Further, based on the above embodiments of the present invention, referring to fig. 15, fig. 15 is a schematic diagram illustrating alignment between a light shielding matrix region and a light control panel in a display panel according to an embodiment of the present invention.

The display panel includes: and a color film substrate.

And a shading matrix 21 is arranged on the color film substrate.

In a direction perpendicular to the display panel, an orthogonal projection area of the light-shielding matrix 21 covers an orthogonal projection area of the second data line 16 and an orthogonal projection area of the second gate line 15.

The light-shielding matrix 21 is located in the first light-shielding region a 1.

In this embodiment, since the shape of the area defined by the intersection of the first data line 12 and the first gate line 11 is similar to the shape of the area defined by the intersection of the second data line 16 and the second gate line 15, the position of the second data line 16 and the second gate line 15 is optimized so that the orthographic projection area of the light-shielding matrix 21 in the display panel covers the orthographic projection area of the second data line 16 and the orthographic projection area of the second gate line 15.

That is to say, the shading matrix 21 on the display panel blocks the metal lines (the second data lines 16 and the second gate lines 15) on the light control panel, so that the manufacturing process of the dual-screen display panel is simplified, and the manufacturing cost is reduced.

Further, referring to fig. 16 based on the above embodiments of the present invention, fig. 16 is a schematic diagram illustrating alignment between a black matrix region and a light control panel in another display panel according to an embodiment of the present invention.
