In a display panel using a side-entry light source, the temperature of the display panel is higher as it approaches the light source, and the temperature is lower as it approaches the light source. Since the higher the temperature is, the lower the transmittance of the liquid crystal layer in the display panel is, the lower the temperature is, and the higher the transmittance of the liquid crystal layer 12 in the display panel is, resulting in uneven brightness of the entire display panel. To this end, the present application provides a display panel using a side-in light source but having uniform brightness throughout the display panel, and a display device using the same.

Referring to fig. 1 and 2, a display device 100 according to a first embodiment of the present application includes a display panel 10 and a side-entry backlight module 20. Wherein the display panel 10 includes a first substrate 11, a liquid crystal layer 12, and a second substrate 13; the first substrate 11 and the second substrate 13 are arranged opposite to each other, and the liquid crystal layer 12 is arranged between the first substrate 11 and the second substrate 13; the side-entrance backlight module 20 includes a light guide plate 21 and a light source 22. The side-entry backlight module 20 may further include other functional layers, such as a reflective layer, without limitation.
Specifically, when the display device 100 is in operation, the light emitted from the light source 22 enters the display panel 10 through the light guide plate 21, the light entering the display panel 10 passes through the second substrate 13 and then passes through the liquid crystal layer 12, the arrangement mode of the liquid crystal molecules 120 in the liquid crystal layer 12 changes the polarization angle of the light, and finally the light exits through the first substrate 11, so that a corresponding picture is displayed. Therefore, the intensity and color of the light finally appearing can be controlled by changing the voltage applied to the liquid crystal molecules 120, so that the color combination with different hues can be changed on the display panel 10.
Referring to fig. 2, in the first embodiment of the present application, the first substrate 11 includes an upper polarizing layer 111, an upper glass substrate 112, a common electrode 113, a color filter layer 114, and a black matrix layer 115, which are stacked. The second substrate 13 includes a lower polarizing layer 131, a substrate 132, a TFT (Thin Film Transistor ) structure layer 133, and a pixel electrode array 14, which are stacked. The first substrate 11 and the second substrate 13 may further include other functional layers, such as an alignment layer, which is not limited herein. The first substrate 11 may be a color film substrate, the second substrate 13 may be an array substrate, and the substrate 132 may be a glass substrate.
The second substrate 13 is formed with a plurality of sub-pixels 135, each sub-pixel 135 includes a data line 1351, a scan line 1352, a thin film transistor 1353, and a pixel electrode 142, where the data line 1351, the scan line 1352, and the thin film transistor 1353 are disposed in the TFT structure layer 133, the gate electrode of the thin film transistor 1353 is connected to the scan line 1352, the source electrode and the drain electrode of the thin film transistor 1353 are electrically connected to the data line 1351 and the pixel electrode 142, for example, the source electrode of the thin film transistor 1353 is electrically connected to the data line 1351, and the drain electrode of the thin film transistor 1353 is electrically connected to the pixel electrode 142. It will be appreciated that the second substrate 13 has a plurality of data lines 1351 and scan lines 1352 arranged in a crossing manner, the plurality of data lines 1351 and scan lines 1352 arranged in a crossing manner define a plurality of pixel areas, and two adjacent data lines 1351 and two adjacent scan lines 1352 define a pixel area, within each of which one or more pixel electrodes 142 may be disposed. The present application will be described by taking one pixel electrode 142 provided in each pixel region as an example.
The transmittance T of the liquid crystal layer 12 is expressed as follows:
(formula 1);
(formula 2);
(formula 3);
wherein,,is the azimuth angle between the absorption axis of the upper and lower polarizing layers 111 and 131 and the long axis of the liquid crystal molecules 120, which is determined by the liquid crystal photoalignment, +.>Is of circumference rate>For the refractive index difference of the liquid crystal molecules 120 +.>Is thick in the liquid crystal cell.
Referring to FIG. 3, A is a periodic function for the VA display mode to maximize the transmittanceT, azimuth angleTypically 45 ° where a=1, equation 1 can be simplified to equation 3.
Due to the display device 100 employing the side-entry backlight module 20, the temperature of the display panel 10 is higher as it approaches the light source 22, and the temperature is lower in the first direction a as it is farther from the light source 22. Referring to FIG. 4, the higher the temperature, the refractive index difference of the liquid crystal molecules 120The lower the luminance of the display panel 10, the lower the luminance, resulting in the display panel 10 becoming larger gradually in the first direction a away from the light source 22, the more the transmittance T of the liquid crystal layer 12 becomes, in particular, the luminance of the display panel 10 becomes larger gradually, resulting in uneven luminance.
As can be seen from equations 1, 2 and 4, the azimuth angle is in the range of 0-45 degreesThe larger the refractive index of the liquid crystal molecules 120 is, the higher the brightness of the display panel 10 is. Therefore, in order to solve the problem of uneven brightness of the display panel 10 caused by the side-in backlight module 20, referring to fig. 5, the pixel electrode array 14 on the second substrate 13 in the display panel 10 provided by the present application is divided into a plurality of regions 141 in the first direction a, and each region 141 includes a plurality of pixel electrodes 142 arranged along the first direction a; the slit angles of the pixel electrodes 142 in the same region 141 are the same, and the slit angles of the pixel electrodes 142 in the plurality of regions 141 gradually decrease in the first direction a, so that the transmittance T of the liquid crystal layer 12 in the display panel 10 decreases between the first directions a, thereby compensating for the influence of the temperature difference of the display panel 10 in the first direction a on the transmittance T of the liquid crystal layer 12 in the display panel 10, and ensuring the uniform brightness of the display panel 10.
Referring to fig. 5 and 6, in order to provide the display panel 10 with better wide viewing angle characteristics and to improve the problem of uneven brightness, the present application adopts a multi-domain VA technology (Multidomain Vertical Alignment, MVA), i.e., one pixel electrode 142 is divided into a plurality of regions. Specifically, the pixel electrode 142 includes a main electrode 1421 and a plurality of branch electrodes 1422 connected to the main electrode 1421, where the main electrode 1421 is in a cross shape, the main electrode 1421 divides the pixel electrode 142 into four regions, any one region includes a plurality of branch electrodes 1422 arranged in parallel, and an included angle between the branch electrodes 1422 and the main electrode 1421 is a slit angle of the pixel electrode 142. The plurality of pixel electrodes 142 are arranged in an array, the plurality of pixel electrodes 142 parallel to the first direction a in the pixel electrode array 14 are rows of the pixel electrode array 14, the plurality of pixel electrodes 142 perpendicular to the first direction a are columns of the pixel electrode array 14, and since the temperature of the display panel 10 is only related to the distance from the light source 22, the plurality of pixel electrodes 142 on the same column of the pixel electrode array 14 having the same distance from the light source 22 are the same as the distance from the light source 22, that is, the plurality of pixel electrodes 142 on the same column of the pixel electrode array 14 have the same temperature, therefore, by dividing the pixel electrode array 14 into a plurality of areas 141 in the row direction, the slit angle of the pixel electrodes 142 in the plurality of areas 141 is gradually reduced in the row direction, thereby ensuring that the transmittance T of the liquid crystal layer 12 in the whole display panel 10 is substantially the same, and the brightness of the display panel 10 is uniform. Wherein the number of rows and the number of columns in the pixel electrode array 14 may be the same or different. For example, if the display panel 10 is square, the number of rows and columns may be set to be the same; if the display panel 10 is rectangular, the number of rows and columns may be different according to the side length of the rectangle; if the display panel 10 has other shapes, such as a circular shape or an oval shape, the plurality of pixel electrodes 142 may be arranged in different arrays according to practical situations. The number of the plurality of pixel electrodes 142 in each column in the different regions 141 may be the same or different, for example, referring to fig. 5, the pixel electrode array 14 is divided into 3 regions 141 in the first direction a, the number of the pixel electrodes 142 in each row in the first region 1411 close to the light source 22 is x, the number of the pixel electrodes 142 in each row in the third region 1413 far from the light source 22 is y, and the number of the pixel electrodes 142 in each row in the second region 1412 located between the two regions 141 is z, which may be specifically set according to the actual situation as long as it is ensured that the slit angle of the pixel electrodes 142 in the plurality of regions 141 gradually decreases in the first direction a.
It can be appreciated that in the case where an electric field is applied to the pixel electrode 142, the liquid crystal molecules 120 are turned over in the slit angle direction of the pixel electrode 142, i.e., the deflection angle of the liquid crystal molecules 120 is the same as the slit angle of the pixel electrode 142 in the operating state of the display panel 10. While the lower the temperature, the lower the refractive index difference of the liquid crystal molecules 120The larger the transmittance T of the display panel 10 is, the larger the transmittance T of the display panel 10 in the first direction a away from the light source 22 is, the smaller the slit angle of the pixel electrode 142 in the plurality of regions 141 is by gradually decreasing in the first direction a away from the light source 22, so that the deflection angle of the liquid crystal molecules 120 controlled by each region 141 is gradually decreased, so that the transmittance T of the display panel 10 in the first direction a is maintained substantially unchanged. Specifically, the application compensates the influence of the temperature difference on the transmittance T of the liquid crystal layer 12 in the display panel 10 in the first direction A by differentially compensating the transmittance T of the display panel 10 in the first direction A, thereby ensuring the uniform brightness of the display panel 10.
In the present embodiment, the number of the pixel electrodes 142 arranged in the first direction a in each region 141 is greater than N, and the number of N is specifically determined according to the number of the plurality of pixel electrodes 142 in the pixel electrode array 14 divided into the regions 141. Since each region 141 includes a plurality of pixel electrodes 142, the plurality of regions 141 divide the pixel electrode array 14 into a limited number of units, if the slit angle of the pixel electrode 142 in the adjacent two regions 141 is too small, the variation of the slit angle of the pixel electrode 142 in the plurality of regions 141 in the first direction a is small, for example, the pixel electrode array 14 is divided into 3 regions 141 in the first direction a, if the difference of the slit angles of the pixel electrode 142 in the adjacent two regions 141 is 0.5 degrees, the variation of the slit angle of the pixel electrode 142 in the plurality of regions 141 in the first direction a is only 1.5 degrees, the compensation of the transmittance T of the liquid crystal layer 12 in the display panel 10 is small, and the brightness of the display panel 10 in the first direction a still has a certain difference. In this embodiment, the difference of the slit angles of the pixel electrodes 142 in the adjacent two regions 141 is 3-6 degrees in the first direction a, and specifically, the difference can be selected according to the size or temperature of the display panel 10 in the first direction a, so as to compensate the influence of the temperature difference of the display panel 10 in the first direction a on the transmittance T of the liquid crystal layer 12 in the display panel 10, so that the brightness of the display panel 10 is uniform.
In the present embodiment, referring to fig. 6, in the first direction a, the slit angle of the pixel electrode 142 in the plurality of regions 141 decreases from 45 degrees. For example, the number of the plurality of regions 141 is three, slit angles of the pixel electrodes 142 in the three regions 141 are Φ1, Φ2, Φ3 in order in the first direction a, and Φ1> Φ2> Φ3. Specifically, the higher the temperature and the lower the transmittance T of the display panel 10 at a position closer to the light source 22, the transmittance T of the liquid crystal layer 12 at the position closer to the light source 22, that is, the transmittance T at the first region 1411 is maximally improved by setting the angle of the slit angle of the pixel at the position closer to the light source 22 to 45 degrees. Wherein, phi 1 is 45 degrees, phi 2 is 40 degrees, phi 3 is 35 degrees, so that the transmittance T of the display panel 10 in the first direction A is sequentially weakened, and the influence of different temperatures on the display panel 10 on the transmittance T is further compensated. Wherein, the minimum slit angle of the plurality of pixel electrodes 142 ranges from 30 degrees to 40 degrees. For example, in the first direction a, the slit angle of the pixel electrode 142 farthest from the light source 22 may be 40 degrees, 35 degrees, 30 degrees, etc., and may be specifically determined according to the number of the regions 141 and the difference of the slit angles of the pixel electrodes 142 in the adjacent two regions 141.
In this embodiment, the number of the plurality of regions 141 is 3-6, which can be specifically selected according to the size or temperature of the display panel 10 and the influence of the display panel 10 in the first direction a, for example, the plurality of regions 141 sequentially include the first region 1411, the second region 1412 and the third region 1413 in the first direction a, the slit angle of the pixel electrode 142 in the second region 1412 is set to be the standard slit angle Φ2, the angle of the slit angle Φ1 of the pixel electrode 142 in the first region 1411 is increased, the angle of the slit angle Φ3 of the pixel electrode 142 in the third region 1413 is reduced, so as to increase the transmittance T of the first region 1411, reduce the transmittance T of the third region 1413, and make the transmittance T of the liquid crystal layer 12 in the first direction a substantially the same, so as to ensure the uniform brightness of the display panel 10. It can be understood that the greater the number of the regions 141, the greater the variation value of the slit angle of the pixel electrode 142, resulting in a complicated manufacturing process.
In order to make the brightness of the display panel 10 more uniform, in the present embodiment, the difference in slit angles of the pixel electrodes 142 in the adjacent two regions 141 is equal in the first direction a. For example, in the first direction a, the difference in slit angles of the pixel electrodes 142 in the adjacent two regions 141 is 3 degrees, 4 degrees, 5 degrees, or 6 degrees.
Referring to fig. 7A to 7C, the pixel electrode 142 shown in fig. 7A to 7C is merely an exemplary illustration, and the specific structure is substantially the same as that of the pixel electrode 142 shown in fig. 6.
Referring to fig. 7A, the sub-pixel 135 provided by the present application further includes a common electrode trace 1354, where the common electrode trace 1354 and each pixel electrode 142 are partially overlapped to form a storage capacitor, and in the first direction a, the overlapping area of each pixel electrode 142 in the same area and the common electrode trace 1354 is the same, and the overlapping areas of the pixel electrodes 142 in multiple areas and the common electrode trace 1354 are gradually reduced in the first direction a.
Specifically, the common electrode trace 1354 is disposed in the TFT structure layer 133, for example, the common electrode trace 134 is disposed in the same layer as the scan line 1352. The common electrode 113 is electrically connected with each sub-pixel 135 through the common electrode wiring 1354, a storage capacitor is formed between the common electrode wiring 1354 and each pixel electrode 142 in a matching manner, the storage capacitor can keep the brightness of the display panel 10 stable, the larger the capacitance value of the storage capacitor is, the longer the brightness of the display panel 10 is kept, the overlapping area of each pixel electrode 142 in the same area and the common electrode wiring 1354 is set to be the same in the first direction A, the overlapping area of the pixel electrodes 142 in a plurality of areas and the common electrode wiring 1354 is gradually reduced in the first direction A, the storage capacitors of a plurality of areas in the first direction A are gradually reduced, and the influence of different temperatures on the transmittance T on the display panel 10 is further compensated by differentiation, so that the overall brightness of the display panel 10 is more uniform.
Specifically, the larger the projected coverage area of the common electrode trace 1354 on each pixel electrode 142, the larger the capacitance value of the storage capacitance formed between the common electrode trace 1354 and each pixel electrode 142, referring to fig. 7A, in the first direction a, the embodiment sets the projected overlapping area of each pixel electrode 142 in the first area 1411 and the common electrode trace 1354 to be S1, sets the projected overlapping area of the pixel electrode 142 in the second area 1412 and the common electrode trace 1354 to be S2, sets the projected overlapping area of the pixel electrode 142 in the third area 1413 and the common electrode trace 1354 to be S3, and sets S1> S2> S3. As can be appreciated, the area of the display panel 10 closer to the light source 22 is more affected by temperature, and the present embodiment reduces the influence of the light source 22 on the transmittance T of different areas of the liquid crystal layer 12 by differentially setting the projection overlapping area of the pixel electrode 142 and the common electrode trace 1354 in the plurality of areas in the first direction a, so that the brightness of the display panel 10 is uniform.
In this embodiment, as shown in fig. 7A, the pixel electrode 142 further has an opening area 1423 for circulating light, the light emitted from the light source 22 enters the liquid crystal layer 12 through the opening area 1423, the size of the common electrode trace 1354 is unchanged by changing the size of the pixel electrode 142 in different areas, so that in the first direction a, the overlapping area of each pixel electrode 142 and the common electrode trace 1354 in the same area is the same, and the overlapping area of the pixel electrode 142 and the common electrode trace 1354 in multiple areas gradually decreases in the first direction a. The opening region 1423 in the present application refers to a region of the pixel electrode 142 not covered by the metal layer (e.g., the common electrode trace 1354), and an opening allowing light to pass through is formed in the opening region 1423. In this embodiment, the size of the common electrode trace 1354 may be changed, and the size of the pixel electrode 142 is unchanged, so that the overlapping area of each pixel electrode 142 in the same area and the common electrode trace 1354 is the same in the first direction a, and the overlapping areas of the pixel electrodes 142 in a plurality of areas and the common electrode trace 1354 are gradually reduced in the first direction a. Of course, the sizes of the pixel electrode 142 and the common electrode trace 1354 may not be changed, and by changing the relative positions of the pixel electrode 142 and the common electrode trace 1354, the overlapping area of each pixel electrode 142 and the common electrode trace 1354 in the same area is the same in the first direction a, and the overlapping area of the pixel electrode 142 and the common electrode trace 1354 in a plurality of areas is gradually reduced in the first direction a, which is not limited herein.
There may also be a coupling capacitance in the display panel 10, for example, between the pixel electrode 142 and the data line 1351, or between the pixel electrode 142 and the scan line 1352. And the effect of the coupling capacitance is opposite to that of the storage capacitance, the larger the coupling capacitance is, the shorter the luminance of the display panel 10 is maintained. For this reason, the present application can also adjust the luminance uniformity of the display panel 10 using the coupling capacitance. Specifically, since the coupling capacitance between the pixel electrode 142 and the data line 1351 is relatively obvious, and other coupling capacitances are negligible, the present application is described by taking the coupling capacitance between the pixel electrode 142 and the data line 1351 as an example. In the present application, in the first direction a, the coupling capacitance between each pixel electrode 142 and the data line 1351 in the same area is the same, and the coupling capacitance between the pixel electrode 142 and the data line 1351 in the first direction a in different areas is larger and larger. For example, referring to fig. 7B, in the first direction a, the distances between the pixel electrodes 142 and the data lines 1351 in the three regions are d1, d2, d3 in order, and d1> d2> d3. The present application can gradually decrease the distance between the pixel electrode 142 and the data line 1351 without affecting the aperture ratio of the display panel 10 by gradually increasing the width (refer to the dimension along the first direction a) of the pixel electrode 142 in different regions in the first direction a.
It can be understood that in order to keep the aperture ratio of the display panel 10 unchanged, the common electrode trace 1354 remains unchanged in the first direction a. If only the width of the pixel electrode 142 is gradually increased, the overlapping area of the pixel electrode 142 and the common electrode wiring 1354 is gradually increased, i.e., the storage capacitance is gradually increased. Referring to fig. 7C, for this reason, the present application gradually reduces the length (referring to the dimension in the direction perpendicular to the first direction a) of the pixel electrode 142 while gradually increasing the width of the pixel electrode 142 of the different region in the first direction a, thereby gradually reducing the storage capacitance of the sub-pixel 135 in the different region in the first direction a.
Referring to fig. 8 and 9, a display device 100 according to a second embodiment of the present application includes a display panel 10 and a side-entry backlight module 20. Wherein the display panel 10 includes a first substrate 11, a liquid crystal layer 12, and a second substrate 13; the first substrate 11 and the second substrate 13 are arranged opposite to each other, and the liquid crystal layer 12 is arranged between the first substrate 11 and the second substrate 13; the side-entrance backlight module 20 includes a light guide plate 21 and a light source 22.
The display device 100 according to the second embodiment of the present application has substantially the same structure as the display device 100 according to the first embodiment of the present application, except that the display device 100 according to the second embodiment of the present application further includes a scattering layer 15. Specifically, the scattering layer 15 is disposed corresponding to the boundary between two adjacent regions 141.
In the present embodiment, the number N of the pixel electrodes 142 in each region 141 in the first direction a is 10 or more and 20 or less. Specifically, if the number of the pixel electrodes 142 in each of the regions 141 is less than N, for example, less than 10, in the first direction a, the process difficulty of the product is increased; in the first direction a, if the number of the pixel electrodes 142 in each region 141 is greater than N, for example, greater than 20, the number of the divided regions 141 is reduced, and since the plurality of rows of the pixel electrodes 142 in each region 141 all use the same slit angle, if the difference of the slit angles of the pixel electrodes 142 in two adjacent regions 141 is too small and the number of the regions 141 is smaller, the compensation effect is not obvious, and if the difference of the angle of the pixel electrodes 142 in two adjacent regions 141 is too large and the number of the regions 141 is smaller, the brightness at the boundary of the two adjacent regions 141 is obviously abrupt.
In the second embodiment of the present application, in order to reduce the transmittance T, after compensating for the luminance jump between the two adjacent regions 141, referring to fig. 8, the display panel 10 further includes a scattering layer 15 according to the first embodiment, where the scattering layer 15 is disposed corresponding to the junction between the two adjacent regions 141, and is used for adjusting the luminance difference between the two adjacent regions 141 at the junction, so as to reduce the luminance jump between the two adjacent regions 141, and make the luminance of the display panel 10 uniform. It will be appreciated that since the same slit angle is used for the columns of pixel electrodes 142 in each region 141, the temperature of the display panel 10 corresponding to the columns of pixel electrodes 142 in each region 141 is actually different. Therefore, the temperature of the area of the display panel 10 corresponding to each of the areas 141 is gradually decreased in the first direction a, and the brightness of the area of the display panel 10 corresponding to each of the areas 141 is gradually increased in the first direction a. Therefore, the brightness at the boundary of the adjacent two regions 141 may be abrupt. For example, a side of the first region 1411 near the second region 1412 is a position of maximum luminance of the first region 1411, and a side of the second region 1412 near the first region 1411 is a position of minimum luminance of the first region 1411, and thus, luminance may be suddenly changed at a boundary between the first region 1411 and the second region 1412. Specifically, the scattering layer 15 is a scattering particle layer disposed on the first substrate 11, and the scattering particle layer can scatter light to play a role of blurring a boundary of light, and is used for scattering and mixing light with different light intensities at two sides of a boundary of two adjacent regions 141, so as to eliminate abrupt brightness changes at the boundary of two adjacent regions 141. By arranging the projection of the scattering layer 15 on the pixel electrode array 14 at the junction of the two adjacent areas 141, the light rays on two sides of the display panel 10 corresponding to the junction of the two adjacent areas 141 are uniform. Specifically, the scattering particle layer may be disposed on a surface of the upper polarizing layer 111 away from the second substrate 13, and a projection of the scattering particle layer on the second substrate 13 is located at a junction between two adjacent regions 141; the scattering particle layer may also be disposed in the gap in the black matrix layer 115, and the projection of the scattering particle layer on the second substrate 13 is located at the junction of the two adjacent regions 141, so that the brightness at the junction of the two adjacent regions 141 is uniform.
In this embodiment, referring to fig. 9, the projection of the scattering layer 15 on the second substrate 13 covers at least the portions of the adjacent two pixel electrodes 142 at the junction of the adjacent two regions 141. For example, a side of the first region 1411 near the second region 1412 is a position of maximum brightness of the first region 1411, and a side of the second region 1412 near the first region 1411 is a position of minimum brightness of the first region 1411, so that a projection of the scattering layer 15 on the second substrate 13 is disposed to cover at least a portion of the adjacent two pixel electrodes 142 at a junction of the adjacent two regions 141, and a strong light ray at a side of the first region 1411 near the second region 1412 and a weak light ray at a side of the second region 1412 near the first region 1411 are mixed into a light ray of the same intensity by the scattering layer 15 and scattered, thereby eliminating a sudden brightness change at the junction of the adjacent two regions 141. In this embodiment, the projection of the scattering layer 15 on the second substrate 13 can cover the gap between the two adjacent columns of pixel electrodes 142 of the first region 1411 and the second region 1412, and can cover at least part of the pixel electrode 142 on one side of the first region 1411 near the second region 1412, and at least part of the pixel electrode on one side of the second region 1412 near the first region 1411, so as to scatter the light with different light intensities on both sides of the junction between the two adjacent regions 121 in a mixed manner. In this embodiment, the area of the pixel electrode 142 covering the side of the first region 1411 near the second region 1412 of the scattering layer 15 on the second substrate 13 may also be larger than the area of the pixel electrode 142 covering the side of the second region 1412 near the first region 1411, for example, the projection of the scattering layer 15 on the second substrate 13 completely covers the pixel electrode 142 of the first region 1411 near the row of the second region 1412, and the projection of the scattering layer 15 on the second substrate 13 covers half of the area of the pixel electrode 142 of the second region 1412 near the row of the first region 1411, so as to increase the scattering ratio of the strong side light to improve the brightness of the weak side light, so that the brightness of the display panel 10 is uniform.
The display panel 10 and the display device 100 provided by the application comprise a substrate and a plurality of sub-pixels 135 arranged on the substrate, wherein the sub-pixels 135 comprise pixel electrodes 142, the substrate is divided into a plurality of areas in a first direction A, and each area comprises a plurality of pixel electrodes 142 arranged along the first direction A; the slit angles of the pixel electrodes 142 in the same area are the same, the slit angles of the pixel electrodes 142 in a plurality of areas gradually decrease in the first direction a, when the display device 200 employing the display panel 10 employs the side-entry backlight module 20, the transmittance T of the liquid crystal layer 12 gradually increases due to the gradual decrease of the temperature of the display panel 10 in the first direction a, and the slit angles of the pixel electrodes 142 in a plurality of areas of the array substrate gradually decrease in the first direction a, so that the transmittance T of the liquid crystal layer 12 gradually decreases, thereby compensating for the influence of the temperature difference of the display panel 10 on the transmittance T of the liquid crystal layer 12 in the first direction a when the display device 100 operates, and making the brightness of the display panel 10 uniform.
The foregoing is only the embodiments of the present application, and therefore, the patent scope of the application is not limited thereto, and all equivalent structures or equivalent processes using the descriptions of the present application and the accompanying drawings, or direct or indirect application in other related technical fields, are included in the scope of the application.
