And, upper substrate 1 and infrabasal plate 2 correspond and set up, provide the installation basis for other structures. The pixel units 3 are disposed between the upper substrate 1 and the lower substrate 2, and include color filter films 31, liquid crystal molecules 32 and control electrodes 33 for controlling a liquid crystal display screen, and a light-transmitting gap 5 is further disposed between the color filter films 31 corresponding to two partially adjacent pixel units 3. The specular reflection layer 4 is disposed on the lower substrate 2 and is disposed corresponding to the light-transmitting gap 5, and the specular reflection layer 4 forms a reflection mirror surface through the light-transmitting gap 5.

In the embodiment of the present application, the pixel unit 3 is configured to perform the original display screen function of the mirror reflection liquid crystal display panel, and the mirror reflection layer 4 and the light transmission gap 5 are configured to perform the mirror imaging function. Thus, the mirror reflection liquid crystal display panel provided by the embodiment of the application can simultaneously play a picture display function and a mirror imaging function. For the convenience of distinction, the part of the specular reflection liquid crystal display panel corresponding to the light-transmitting gap 5 for specular imaging is called a specular reflection area; the portion of the mirror reflection liquid crystal display panel corresponding to the color filter 31 for displaying the image is referred to as a display area, and specifically, reference may be made to "mirror reflection area" and "display area" in fig. 2 to 7.

It should be noted that, in the embodiment of the present application, the specific form of the pixel unit 3 is not limited, and the color filter film 31 of the commonly used pixel unit 3 includes a red color filter film, a green color filter film and a blue color filter film, which are commonly referred to as RGB three primary colors, and the arrangement of the liquid crystal molecules 32 corresponding to the RGB three primary colors is controlled by the control electrode 33, so that the display color image can be controlled. Of course, in the present embodiment, there may be other color filter films 31 besides the RGB color filter films 31, for example, there may be a white color filter film 31 in a liquid crystal display panel, and the present embodiment is not limited to this. In this application, a description will be given of a specular reflection liquid crystal display panel provided in an embodiment of the present application with an RGB color filter film 31 as an example. Here, the pixel cell 3 is the smallest cell for displaying a screen, and therefore, the color filter film 31 is also the color filter film 31 for the smallest cell for displaying a screen, and here, the color filter film 31 may be the color filter film 31 corresponding to an individual R subpixel point, the color filter film 31 corresponding to an individual G subpixel point, or the color filter film 31 corresponding to an individual B subpixel point. Correspondingly, the light-transmitting gap 5 may be provided between the color filter films 31 of the above-described minimum unit. For convenience of description, the color filter film 31 corresponding to the R pixel is referred to as R, the color filter film 31 corresponding to the G pixel is referred to as G, the color filter film 31 corresponding to the B pixel is referred to as B, and the light-transmitting gap 5 is referred to as C, in the embodiment of the present application, the light-transmitting gap 5 and the RGB are arranged in various ways, such as: RCGCBCRCGCBC \8230 \ (light-transmitting gaps 5 are provided between each R, G and B pixel point), RCGCBRCGCB \8230 \ (light-transmitting gaps 5 are provided in one RGB pixel) or rgbcgbc \8230; (light-transmitting gaps 5 are provided between adjacent RGB pixels), and the like, for example, in the embodiment of the present application, the light-transmitting gaps 5 are provided by way of example in the rgbcrcgcbcrcgcbc \8230; \8230.

In the present application, the pixel unit 3 refers to the color filter film 31, the liquid crystal molecules 32, and the control electrode 33 that correspond to each other in the thickness direction of the liquid crystal panel. In the drawings of the present application, for the convenience of marking, the marks for the color filter film 31, the liquid crystal molecules 32, and the control electrodes 33 may not be corresponded in the thickness direction of the liquid crystal panel, and this should not be misunderstood.

In the present embodiment, the arrangement of the pixel units 3 is not limited, and for example, a standard RGB arrangement, an RGGB arrangement, or a diamond arrangement may be used for the three primary colors of RGB, and the light-transmitting gap 5 in the present embodiment may be adaptively provided regardless of the arrangement.

It should be noted that the light-transmitting gap 5 may be a space between adjacent color filter films 31, that is, no structure is provided between adjacent color filter films 31, so that ambient light can transmit through the space between adjacent color filter films 31; in addition, the light-transmitting gap 5 may be a light-transmitting material, such as transparent glass, provided between the adjacent color filter films 31. In the embodiment of the present application, the light-transmitting gap 5 may be provided between some of the adjacent color filter films 31, or the light-transmitting gap 5 may be provided between all of the adjacent color filter films 31. For example, for the specular reflection liquid crystal display panel used in the fitness or dance courses, the light-transmitting gap 5 may be disposed in the middle of the display panel, so as to meet the user's requirement and not affect the display resolution of other parts of the display panel.

In addition, in the present embodiment, the form of the control electrode 33 is not limited, and a Twisted Nematic (TN), a Super Twisted Nematic (STN), and a Thin Film Transistor (TFT) are commonly used, and the TFT type control electrode 33 and the TFT which are mainly used at present are also called "active matrix Thin Film Transistor", which are devices for actively controlling the light throughput per pixel point. In the present application, the description will be given of the specular reflection liquid crystal display panel provided in the embodiments of the present application, taking the TFT-type control electrode 33 as an example.

Referring to fig. 1, there is shown a schematic view of a structure of a specular reflection liquid crystal display panel in the related art, in which an Ag layer is sputtered under a protective glass 66 at the upper end of a liquid crystal cell as a specular reflection layer 4. However, this arrangement causes the Ag layer to block most of the light transmission, makes the transmittance of the liquid crystal display panel very low, and requires an increase in power consumption of the liquid crystal display panel in order to display a regular luminance. It is estimated that if it is desired to exhibit a luminance of 400 nits for a conventional display, the power consumption needs to be increased by 2.5 to 5 times.

The scheme provided by the embodiment of the application can improve the light transmittance of the liquid crystal display panel and reduce the power consumption of the liquid crystal display panel.

Specifically, referring to fig. 2 and 3, an exemplary TFT-LCD-based specular reflection liquid crystal display panel provided in an embodiment of the present invention is shown in fig. 2 and 3, and the specular reflection liquid crystal display panel provided in the embodiment of the present invention includes an upper substrate 1, a lower substrate 2, a pixel unit 3, and a specular reflection layer 4. The upper substrate 1 and the lower substrate 2 are disposed correspondingly, a receiving space is formed between the upper substrate 1 and the lower substrate 2, and a color filter film 31, liquid crystal molecules 32, an alignment film 61, a protective layer 73, a buffer layer 71, a control electrode 33, and the like are disposed in the receiving space. For the TFT-LCD, the upper substrate 1 and the lower substrate 2 form a parallel plate capacitor, and the control electrode 33 includes: a source electrode 331, a drain electrode 332, and a gate electrode 333, and an organic semiconductor active layer 334. Indium Tin Oxide (ITO) is further disposed on the upper substrate 1, so that the upper substrate 1 forms a common electrode, and a voltage applied to the gate electrode 333 is used to control a current between the source electrode 331 and the drain electrode 332, and further control a distribution of an electric field between the upper substrate 1 and the lower substrate 2, thereby controlling an arrangement of the liquid crystal molecules 32 to display an image.

Referring to fig. 2, in the embodiment of the present application, each pixel unit 33 includes a minimum color filter film 31 structure, as shown in fig. 2, a light-transmitting gap 5 is disposed between adjacent color filter films 31, and it should be noted that, for convenience of illustration, the color filter film 31 on the right side in fig. 2 is not shown, and may be disposed in a straight line arrangement according to the structure on the left side of the light-transmitting gap 5. It should be noted that, in some embodiments of the present application, a Black Matrix (BM) 64 may be further disposed between adjacent color filter films, and the main function of the Black Matrix 64 is to prevent light from leaking out in the non-display area, so as to shield light.

It should be noted that, in order to facilitate the fabrication of the light-transmitting gap 5, the width of the light-transmitting gap 5 may be set to be the same as the width of the color filter 31, so that when the light-transmitting gap 5 is fabricated, the light-transmitting gap 5 may be treated as a special color filter 31. For RGB, various thin films on the upper substrate 1, such as the black matrix 64, and the color filter films 31 corresponding to RGB are coated on the surface of the upper substrate 1 by a coating process, and therefore, the specular reflection layer 4 can be coated on the surface of the upper substrate 1 corresponding to the light transmission gap 5 by referring to the above process, so that the specular reflection layer 4 can be manufactured by fully using the optical materials existing in the liquid crystal display panel.

In addition, in the embodiment of the present application, referring to fig. 2, the specular reflection layer 4 may be disposed at any position between the light transmission gap 5 and the lower substrate 2 corresponding to the light transmission gap 5 in the thickness direction of the liquid crystal display panel, for example, may be disposed in the light transmission gap 5, may be disposed on the surface of the alignment film 61 corresponding to the light transmission gap 5, and may be disposed on the upper surface of the lower substrate 2 corresponding to the light transmission gap 5.

The specular reflection liquid crystal display panel that this application embodiment provided only sets up specular reflection layer 4 corresponding first clearance, compares in the correlation technique along liquid crystal display panel tiling setting specular reflection layer 4, and specular reflection layer 4's in this application area accounts for than less in hard display panel's total area, and is less to liquid crystal display panel's whole luminousness influence, and under the prerequisite that shows the same luminance, the power consumption that needs is littleer.

In some embodiments of the present application, referring to fig. 3, the specular reflection layer 4 is disposed in the light transmission gap 5, which is equivalent to disposing a plurality of "small mirrors" in parallel with the color filter film 31 at intervals, so that the specular image forming function of the specular reflection liquid crystal display panel provided in the embodiments of the present application can be performed. In this way, when the color filter film 31 is manufactured, the specular reflection layer 4 can be manufactured together with the color filter film 31 at the position corresponding to the light-transmitting gap 5, and the manufacturing process of the specular reflection layer 4 can be simplified. In this case, since the specular reflection layer 4 does not have a relationship with the arrangement of the liquid crystal molecules 32 when it performs the mirror imaging function, the control electrode 33 may not be provided below the light transmission gap 5, and the number of the control electrodes 33 can be reduced. The control part of the mirror reflection liquid crystal display panel provided by the embodiment of the application has a simple structure, is easy to manufacture and saves materials.

It should be noted that, in some embodiments of the present application, the specular reflection lcd panel further includes other structures, such as: the liquid crystal display panel comprises a polarizing plate 65 arranged on the upper surface of an upper substrate 1, a protective glass 66 arranged on the outermost layer of the liquid crystal display panel, alignment films 61 arranged on two sides of liquid crystal molecules 32, a buffer layer 71, a gate dielectric layer 72, a protective layer 73, a planarization layer 8, a spacer 67 arranged between the liquid crystal molecules 32, an optical glue 68 filled between the upper substrate 1 and a lower substrate 2, and a pixel electrode 610 and an imaging reflection layer 611 arranged on the upper surface of the planarization layer.

In addition, in some embodiments of the present application, referring to fig. 4, an electrode layer 7 is disposed on an upper surface of the lower substrate 2, the electrode layer 7 including: a buffer layer 71, a gate dielectric layer 72 and a protective layer 73, and an electrode layer 7 for providing the control electrode 33. Meanwhile, a planarization layer 8 is provided on the upper surface of the electrode layer 7. Since the different arrangement positions or rotation states of the liquid crystal molecules 32 are different from each other in the retardation of incident light, which ultimately affects the luminance of the emitted light, the light transmittance is affected and the problem of light transmission is caused due to the sub-pixel step difference and the angular step difference among the three primary colors of RGB, and the above problem can be solved by coating the planarization layer 8 on the upper surface of the electrode layer 7. In the present embodiment, the specular reflection layer 4 can be provided using a planarization layer.

On the basis, referring to fig. 4, in some embodiments of the present application, the specular reflection layer 4 is disposed on the upper surface of the planarization layer 8 corresponding to the light transmission gap 5, where the specular reflection layer 4 is disposed on the planarization layer corresponding to the light transmission gap 5 means that the specular reflection layer 4 is disposed corresponding to the light transmission gap 5 along the thickness direction of the liquid crystal display panel. At this time, the ambient light reaches the specular reflection layer 4 through the light transmission gap 5, is reflected by the specular reflection layer 4 and then exits the light transmission gap 5 to form a reflection picture, and the specular reflection layer 4 forms a reflection mirror, so that the specular reflection liquid crystal panel provided by the embodiment of the present application performs a mirror imaging function. Therefore, light rays corresponding to the whole area of the liquid crystal display panel can be transmitted into the liquid crystal display panel or transmitted out of the liquid crystal display panel, the light transmittance of the mirror reflection liquid crystal display panel provided by the embodiment of the application can be further improved, and the power consumption of the liquid crystal display panel is reduced.

When the specular reflection layer 4 is provided below the liquid crystal molecules 32, it is necessary to provide the control electrode 33 corresponding to the light transmission gap 5 to control the arrangement of the liquid crystal molecules 32 corresponding to the light transmission gap 5, so that light can reach the specular reflection layer 4 through the liquid crystal molecules and be reflected by the specular reflection layer 4 to form a reflection screen. Therefore, the mirror reflection liquid crystal display panel provided by the embodiment of the application can be conveniently manufactured by utilizing the existing manufacturing process of the TFT, the prior art can be fully utilized, and research and development resources are saved.

On this basis, in other embodiments of the present application, the planarization layer 8 includes a first planarization layer 81 and a second planarization layer 82, specifically, the first planarization layer 81 and the second planarization layer 82 are arranged and stacked, and the second planarization layer 82 is disposed above the first planarization layer 81. A reflective gap is also provided between the second planarizing layers 82 along the extending direction of the liquid crystal display panel, and the reflective gap is aligned with the light-transmitting gap 5. The alignment of the reflective gap and the light-transmitting gap 5 means that the projection of the reflective gap and the light-transmitting gap 5 coincide along the thickness direction of the panel. Further, in some embodiments of the present application, a specular reflective layer 4 is disposed within the reflective gap. Like this, set up specular reflection layer 4 in the reflection clearance, can make the upper surface of second planarization layer 82 keep smooth, conveniently make second planarization layer 82 and specular reflection layer 4, simultaneously, also can reduce the preparation degree of difficulty of the specular reflection liquid crystal display panel that this application embodiment provided.

Further, in some embodiments of the present application, the specularly reflective liquid crystal display panel is a reflective liquid crystal display panel. The reflective liquid crystal display panel is a liquid crystal display panel that provides light to the mirror reflection liquid crystal display panel by using ambient light, and in this case, a backlight is not provided on the back of the display panel. Referring to fig. 5, an imaging reflective layer 611 may be disposed between the first and second planarizing layers 81 and 82 to reflect ambient light to provide a light source to the specular reflection liquid crystal display panel. The image formation reflective layer 611 functions to provide a light source for forming an image of liquid crystal to the liquid crystal display panel, and the specular reflective layer 4 functions as a mirror for reflecting ambient light to form a reflective screen.

To make the specular reflective layer 4 using the imaging reflective layer 611, in some embodiments of the present application, the specular reflective layer 4 is disposed flush with the imaging reflective layer 611 such that the specular reflective layer 4 has the same thickness as the imaging reflective layer 611, and the specular reflective layer 4 can be considered as an extension of the imaging reflective layer 611. Thus, the specular reflection layer 4 and the imaging reflection layer 611 can be provided as an integral structure, and the specular reflection layer 4 and the imaging reflection layer 611 can be simultaneously manufactured and completed on the basis of the same process.

Meanwhile, considering that the specular reflection layer 4 and the imaging reflection layer 611 have different functions, the adjustment can also be performed in a targeted manner corresponding to the specular reflection layer 4 and the imaging reflection layer 611. Preferably, for the imaging reflective layer 611, the imaging reflective layer 611 can be set to diffuse reflection, so that the reflection range of light can be increased, and the brightness of the liquid crystal image can be increased; for the specular reflection layer 4, the specular reflection layer 4 may be set to be specular reflection, which may ensure formation of a specular image in conformity with the environmental picture.

In order to improve the mirror image forming effect of the specular reflection layer 4, the planarization rate of the upper surface of the first planarization layer 81 needs to be increased as much as possible. In contrast to setting the thickness of the first planarizing layer 81 to 2 micrometers in the related art, in some embodiments of the present application, setting the thickness of the first planarizing layer 81 to 5 micrometers can significantly improve the planarization rate of the upper surface of the first planarizing layer 81, for example, in some embodiments of the present application, the planarization rate ((step-step)/level difference) of the upper surface of the first planarizing layer 81 can be improved to 95% by setting the thickness of the first planarizing layer 81 to 5 micrometers.

In addition, in some embodiments of the present application, the specular reflection layer 4 is made of indium tin oxide-silver-indium tin oxide (ITO/Ag/ITO), and Ag has a high reflectivity in the visible light range and an excellent photoelectric property, and can be used as a reflection material with a high application value in the visible light band.Meanwhile, the resistivity of Ag is usually 10 ^-6 Omega cm, outstanding conductivity and can be used as electrode material. ITO belongs to photoelectric material, and the resistivity is 10 ^-4 Ω · cm, low resistivity, and high power consumption. Therefore, in some embodiments of the present application, by adopting the ITO/Ag/ITO structure, the characteristics of ITO and Ag can be exerted simultaneously, the power consumption of the display panel can be reduced, and the reflection capability of the specular reflection layer can be improved.

Further, in some embodiments of the present application, a light guide plate 9 is further provided above the upper substrate 1 of the specular reflection liquid crystal display panel, and a compensation light source 91 is further provided.

Specifically, referring to fig. 6, the compensation light source 91 may be disposed at a side surface of the light guide plate 9, and at this time, the compensation light source 91 supplements light to the upper side of the upper substrate 1 through the light guide plate 9, so that the brightness of the specular reflection liquid crystal display panel may be improved.

In addition, in another embodiment of the present application, referring to fig. 7, a micro light emitting diode 911 may be disposed as a compensation light source in the light guide plate 9, which can also improve the brightness of the mirror-reflective liquid crystal display panel. In addition, light can be directly supplemented to the liquid crystal display panel in this manner, and the utilization rate of the compensation light source 91 is improved. However, in this case, a compensation light source control circuit 912 needs to be disposed in the light guide plate 9 to control the on/off of the micro light emitting diodes 911.

In addition, referring to fig. 6 and fig. 7, a touch area may be further disposed in the specular reflection liquid crystal display panel provided in the present application, and the specular reflection liquid crystal display panel provided in the embodiments of the present application may be configured as a touch display panel.
