Description
Technical Field
The present invention relates to a liquid crystal panel, and more particularly, to a liquid crystal panel with a polymer stably aligned.
Background
With the progress of Display technology, compared with the conventional CRT Display, a Thin Film Transistor Liquid Crystal Display (TFT-LCD) has the advantages of lightness, thinness, low radiation, and small size without occupying space, and thus has become a dominant product in the Display market, and is widely applied to various electronic products such as calculators, Personal Digital Assistants (PDAs), notebook computers, Digital cameras, and mobile phones.
In order to further expand the application field and quality of the lcd, the research on the lcd is focused on how to increase the viewing angle and shorten the response time of the screen. In response to the above requirement, the liquid crystal panel is often designed by Multi-domain Vertical Alignment (MVA). Specifically, in the process of manufacturing the liquid crystal panel, the liquid crystal molecules are slightly inclined along the shape of the bump or the opening when no voltage is applied by forming the bump or the opening for alignment control on the common electrode and the pixel electrode. Therefore, when a voltage is applied to the pixel electrode, the liquid crystal molecules are rapidly inclined from a slightly inclined state to a preset direction under the driving of an electric field, so that the screen reaction time is greatly shortened, and the effect of widening the visual angle is achieved.
However, in the prior art, since the MVA technology must use a thin film deposition process, a photolithography process, an etching process, etc. to form a bump or an opening on the common electrode or the pixel electrode, the complexity of the process and the manufacturing cost are increased. In addition, the bumps formed on the substrate often block part of the light, resulting in a reduced pixel aperture ratio, thereby reducing the brightness of the liquid crystal display.
In order to improve the above problems of the liquid crystal panel using the MVA technology, a design for manufacturing the liquid crystal panel using a Polymer Stabilized Alignment (PSA) technology has been developed. By the PSA technology, the high molecular polymer makes the liquid crystal molecules have a pretilt angle, that is, the liquid crystal molecules are influenced by the high molecular polymer to be in inclined arrangement when not being driven by an electric field; when the liquid crystal molecules are driven by the electric field, the liquid crystal molecules can be quickly deflected to a proper orientation, thereby shortening the reaction time of the liquid crystal panel. However, the size of the liquid crystal panel in the prior art is gradually increased, and the above PSA design still fails to solve the problem of color shift at large viewing angles and further fails to reduce the phenomenon of insufficient color saturation (color washout). In addition, the exposure error in the manufacturing process may cause different distribution intervals of the pixel electrodes in different areas of the liquid crystal panel, which may cause uneven brightness.
In view of the above, a problem to be solved by those skilled in the art is how to design a polymer-stabilized alignment liquid crystal panel to improve or eliminate the above-mentioned disadvantages in the prior art.

Detailed Description
In order to make the present disclosure more complete and complete, reference is made to the accompanying drawings, in which like references indicate similar or analogous elements, and to the various embodiments of the invention described below. However, it will be understood by those of ordinary skill in the art that the examples provided below are not intended to limit the scope of the present invention. In addition, the drawings are only for illustrative purposes and are not drawn to scale.
Specific embodiments of various aspects of the present invention are described in further detail below with reference to the accompanying drawings. It should be understood at first that the unit pixel of the present invention includes two sub-pixels each including a pixel electrode, i.e., the first sub-pixel includes a first pixel electrode and the second sub-pixel includes a second pixel electrode. The shape of the first pixel electrode includes a plurality of strip patterns parallel to each other, and the strip patterns extend toward four azimuth angles (e.g., a fishbone pattern). When the unit pixel acts, the electric field generated between the first pixel electrode and the common electrode causes the liquid crystal molecules in the liquid crystal layer to correspondingly deflect according to the electric field. Due to the shape of the first pixel electrode, the liquid crystal molecules are deflected towards four azimuth angles, thereby forming a four-domain (4-domain) effect. In addition, the second pixel electrode in the second sub-pixel has a quad domain effect due to the shape relationship, and thus the unit pixel has an eight domain (8-domain) effect.
In order to shorten the response time of the liquid crystal panel, in the process of manufacturing the liquid crystal panel, a monomer for polymer alignment is added in the liquid crystal layer, and voltage signals are applied to the common electrode and the pixel electrode, so that each liquid crystal molecule is deflected to a predetermined direction, and the monomer is also arranged along with the arrangement direction of the liquid crystal molecules. Then, the monomer is polymerized into a polymer by an energy light (such as visible light or ultraviolet light) or thermal polymerization, and is formed in the liquid crystal panel in an inclined manner.
FIG. 1 is a schematic diagram of a polymer-stabilized-alignment liquid crystal panel according to an embodiment of the present invention. Referring to fig. 1, the polymer sustained alignment liquid crystal panel (hereinafter, referred to as PSA liquid crystal panel) of the present invention includes a plurality of unit pixels, each including a first sub-pixel and a second sub-pixel independent of each other. For convenience of description, the first sub-pixel 10 is taken as a schematic example to illustrate a specific structure. It will be appreciated by those skilled in the art that in some embodiments the structure of the first sub-pixel 10 is equally applicable to the second sub-pixel.
As shown in fig. 1, the first sub-pixel 10 includes four domains (domains), i.e., an upper right domain D1, an upper left domain D2, a lower left domain D3, and a lower right domain D4. Specifically, the domain D1 includes a plurality of bar patterns formed by the first pixel electrodes 101 parallel to each other and a plurality of slits 103 between adjacent first pixel electrodes. The domain D2 includes a plurality of slits 203 between adjacent first pixel electrodes and a plurality of bar patterns formed by the first pixel electrodes 201 parallel to each other. The domain D3 includes a plurality of parallel first pixel electrodes 301 in a stripe pattern and a plurality of slits 303 between adjacent first pixel electrodes. The domain D4 includes a plurality of parallel first pixel electrodes 401 in a stripe pattern and a plurality of slits 403 between adjacent first pixel electrodes. In addition, similar to the first sub-pixel 10, each sub-domain of the second sub-pixel also includes a plurality of strip patterns formed by parallel second pixel electrodes and a plurality of slits between adjacent second pixel electrodes, and the strip patterns of the corresponding sub-domains of the first sub-pixel and the second sub-pixel extend and distribute towards the same direction. For example, the stripe pattern of the sub-field D1, whether it is the first sub-pixel 10 or the second sub-pixel, extends toward the same direction. Preferably, the orientation angles of the extending directions of the strip patterns in the four domains D1-D4 are respectively 40-50 degrees, 130-140 degrees, 220-230 degrees, 310-320 degrees.
It should be noted that each unit pixel of the liquid crystal panel of the present invention further includes at least one diamond pattern P1, the diamond pattern P1 spans each of the four domains D1-D4, and the strip pattern abuts against the boundary of the diamond pattern P1. For example, the diamond pattern P1 is made of Indium Tin Oxide (ITO) material. Compared with the prior art, the invention can reduce the space occupied by the slit between the pixel electrodes through the diamond pattern, thereby improving the uneven brightness caused by the width change of the slit at different positions. In some embodiments, the first sub-pixel of the unit pixel comprises the diamond pattern P1. In some embodiments, the second sub-pixel of the unit pixel comprises the diamond pattern P1. Of course, in other embodiments, both the first and second sub-pixels of a unit pixel include the diamond pattern P1.
Referring again to fig. 1, an identifier L indicates the thickness of the first pixel electrode, and an identifier S indicates the spacing distance (the width of the slit) between two adjacent first pixel electrodes. The specific data of the L48 gray scale are shown below (see Table 1).
TABLE 1
In order to verify that the diamond pattern of the present invention can improve the brightness unevenness, as shown in table 1 above, LS mask values (4.0/2.0, 3.8/2.2, 3.5/2.5, and 3.3/2.7) of four kinds of ITO (indium tin oxide) were designed and tested before and after the diamond pattern was set, respectively, and compared, and as a result, it was also verified that the overall brightness difference of the liquid crystal panel to which the diamond pattern was added was small. In addition, as can also be seen from table 1, when all the unit pixels in the 8 domains (the first sub-pixel 4 domain, the second sub-pixel 4 domain) adopt the slit (slit) pattern, the difference between the brightest and the darkest is as high as 47.2% when L/S of the same gray scale takes different values; in the unit pixel with 8 domains, the first sub-pixel is designed with a diamond pattern, and when the second sub-pixel still adopts a slit pattern, the difference between the brightest and the darkest is only 24.8% when the L/S of the same gray scale takes different values.
FIG. 2 shows an alternative embodiment of the polymer-stabilized aligned liquid crystal panel of FIG. 1. As can be seen from fig. 1 and fig. 2, the main difference between the embodiment shown in fig. 2 and the embodiment shown in fig. 1 is that the liquid crystal panel further includes a first metal electrode M1. The first metal electrode M1 extends along the vertical direction, and two ends of the electrode are respectively located at two angular points of the diamond pattern P1.
FIG. 3 shows another alternative embodiment of the polymer stably aligned liquid crystal panel of FIG. 1. As can be seen from fig. 1 and fig. 3, the main difference between the embodiment shown in fig. 3 and the embodiment shown in fig. 1 is that the liquid crystal panel further includes a first metal electrode M1 and a second metal electrode M2. The first metal electrode M1 extends along the vertical direction and has two ends respectively located at the upper and lower vertices of the diamond pattern P1, and the second metal electrode M2 extends along the horizontal direction and has two ends respectively located at the left and right vertices of the diamond pattern P1. The liquid crystal can be assisted to be inverted by the cross-shaped metal layer through the metal electrodes M1 and M2.
FIG. 4 is a schematic diagram of a polymer-stabilized-alignment liquid crystal panel according to another embodiment of the present invention.
Referring to fig. 4, similarly to fig. 1, in this embodiment, the first sub-pixel 50 of the liquid crystal panel includes four domains. The domain D1 includes a strip pattern formed by a plurality of parallel first pixel electrodes and a plurality of slits between adjacent first pixel electrodes. The liquid crystal panel further includes a metal electrode M1 extending along the vertical direction, and a part of the plurality of slits is in contact with the metal electrode M1 and another part of the slits is not in contact with the metal electrode M1. For example, the slit 501 is in contact with the metal electrode M1, and the slit 503 is not in contact with the metal electrode M1.
In addition, in this embodiment, the first sub-pixel 50 and/or the second sub-pixel further includes a diamond pattern P2, the diamond pattern is disposed across each of the four domains, and two ends of the metal electrode M1 are respectively located at two vertices of the diamond pattern P2. In which a part of the slits (e.g., the slit 501) extending into the diamond pattern P2 is in contact with the metal electrode M1, and another part of the slits (e.g., the slit 503) extending into the diamond pattern P2 is not in contact with the metal electrode M1.
FIG. 5 is a schematic diagram of a polymer-stabilized-alignment liquid crystal panel according to still another embodiment of the present invention.
The main difference between the embodiment shown in fig. 5 and the embodiment shown in fig. 4, in combination with fig. 4 and 5, is that the pattern P3 in the first sub-pixel and/or the second sub-pixel is not a regular diamond pattern and the slits not extending into the pattern P3 are not collinear. For example, the slit 601 extends into the pattern P3 and contacts the metal electrode M1, the slit 605 does not extend into the pattern P3 and abuts against the boundary of the pattern, the slit 603 extends into the pattern P3 but does not contact the metal electrode M1, and the slit 607 does not extend into the pattern P3 and abuts against the boundary of the pattern. For the slits 605 and 607, the pattern boundaries against which they abut are not collinear. It should be noted that, in the patterns of fig. 4 and 5, some slits extend into the patterns, so that a black shadow caused by poor liquid crystal inversion may occur at the slit edge, and the display quality of the liquid crystal panel is slightly worse than that of the embodiments of fig. 1 to 3.
By adopting the PSA liquid crystal panel, each pixel is provided with a first sub-pixel and a second sub-pixel which are independent of each other, each sub-pixel comprises four domains, each domain of the first sub-pixel comprises a strip-shaped pattern formed by a plurality of first pixel electrodes which are parallel to each other and a plurality of slits between adjacent first pixel electrodes, each domain of the second sub-pixel comprises a strip-shaped pattern formed by a plurality of second pixel electrodes which are parallel to each other and a plurality of slits between adjacent second pixel electrodes, each pixel further comprises at least one diamond pattern, the diamond pattern spans each domain of the four domains, and the strip-shaped patterns abut against the boundaries of the diamond patterns. Compared with the prior art, the invention reduces the space occupied by the slit between the pixel electrodes through the diamond pattern, thereby improving the uneven brightness caused by the width change of the slit at different positions.
Hereinbefore, specific embodiments of the present invention are described with reference to the drawings. However, those skilled in the art will appreciate that various modifications and substitutions can be made to the specific embodiments of the present invention without departing from the spirit and scope of the invention. Such modifications and substitutions are intended to be included within the scope of the present invention as defined by the appended claims.
