Description

Technical Field

[0001] The present application relates to the field of display technologies, and particularly to a display panel and a display device. Background Art

[0002] In a liquid crystal display device, the Data Line Sharing (DLS) technology is usually adopted, such that two adjacent columns of sub-pixels share one data line, so as to achieve the effect of halving the data of the data line. However, at the same time, the number of scan lines will double, and further the pixel charging time will be halved, which limits the refresh rate of the display panel. One of the common technologies for improving the refresh rate currently is the technology of simultaneously starting two scan lines, that is, scanning two rows of sub-pixels simultaneously, which can achieve the effect of doubling the refresh rate.

[0003] In the process of researching and practicing the prior art, the inventors of the present application found that there are two problems in the current DLS pixel array: one is that due to the limitation of the pixel array arrangement, the refresh rate cannot be improved by the technology of simultaneously starting two scan lines.

[0039] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application. In addition, it should be understood that the specific implementation manners described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, the embodiments may be combined with each other without further elaboration, and in the case of no contrary description, the orientation terms such as "upper" and "lower" usually refer to the upper and lower in the actual use or working state of the device, specifically the plane direction in the drawings; and "inner" and "outer" refer to the outline of the device; the terms "first", "second", "third", etc. are only used as labels and do not impose numerical requirements or establish an order.

[0040] An embodiment of the present application provides a display panel and a display device, which will be described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments.

[0041] In Figures 1 to 2 , the first direction F1 may be a direction parallel to one side of the display panel 100 in a plan view, and may be, for example, the horizontal direction of the display panel 100. The second direction F2 may be a direction parallel to the other side of the display panel 100 in a plan view, and may be the longitudinal direction of the display panel 100.

[0042] Among them, the display panel 100 is a liquid crystal display panel. The display panel 100 includes a plurality of data lines d1, a plurality of scan lines s1, and a plurality of sub-pixels p1. Two adjacent scan lines s1 form a scan line group s10. The plurality of scan lines s1 and the plurality of data lines d1 are arranged in a crosswise manner to form a plurality of pixel regions x1.

[0043] Two sub-pixels p1 are correspondingly arranged within a pixel region x1. Multiple sub-pixels p1 are arranged in rows along a first direction F1. Multiple sub-pixels p1 are arranged in columns along a second direction F2. A scanning line group s10 is arranged between adjacent two rows of sub-pixels p1, and each scanning line s1 is connected to some of the sub-pixels p1 in one row of sub-pixels p1.

[0044] Optionally, the second direction F2 intersects with the first direction F1. The first direction F1 is parallel to the extending direction of the scanning line s1, and the second direction F2 is parallel to the extending direction of the data line d1. The first direction F1 is perpendicular to the second direction F2, but is not limited thereto.

[0045] It should be understood that the sub-pixels p1 arranged in the display area AA include a pixel electrode p11 and a color filter block arranged in an overlapping manner, wherein the pixel electrode p11 is arranged on the array substrate 10, and the color filter block can be arranged on the array substrate 10 or on the counter substrate.

[0046] Optionally, the color filter block includes a red block, a green block, and a blue block. The sub-pixel p1 having the red block is configured to emit red light, the sub-pixel p1 having the green block is configured to emit green light, and the sub-pixel p1 having the blue block is configured to emit blue light.

[0047] Secondly, the display panel 100 further includes redundant sub-pixels dp1 arranged in the non-display area NA, and the redundant sub-pixels dp1 are configured not to emit light. The redundant sub-pixels dp1 include a redundant pixel electrode and a redundant color filter block arranged in an overlapping manner, wherein the redundant pixel electrode and the pixel electrode p11 are arranged in the same layer, and the redundant color filter block and the color filter block are arranged in the same layer.

[0048] In some embodiments, in the display panel 100 of the embodiments of the present application, in the first direction F1, one side of each data line d1 is connected to the sub-pixel p1 that is separated from it by one column of sub-pixels p1, and the other side of each data line d1 is connected to the sub-pixel p1 that is separated from it by one column of sub-pixels p1. The display panel 100 is configured to activate any one scanning line group s10, and each data line d1 only charges the sub-pixels p1 that emit the same color of light.

[0049] It can be understood that the display panel 100 of the embodiments of the present application realizes that when the double-opening scanning line s1 (activating any one scanning line group s10) is set such that both sides of each data line d1 are connected to the sub-pixels p1 that are separated from it by one column of sub-pixels p1, the same data line d1 can charge the sub-pixels p1 that emit the same color of light, so as to improve the refresh rate of the display panel 100.

[0050] It should be understood that, in the first direction F1, one side of each data line d1 is connected to the sub-pixel p1 that is separated from it by one column of sub-pixels p1, and the other side of each data line d1 is connected to the sub-pixel p1 that is separated from it by one column of sub-pixels p1. In order toFigure 1 As shown in the figure, the first data line d1, the first sub-pixel p1, the second sub-pixel p1, the second data line d1, the third sub-pixel p1 and the fourth sub-pixel p1 are arranged in order from left to right. The left side of the second data line d1 is connected to the first sub-pixel p1 which is separated from it by the second sub-pixel p1, that is, the left side of the second data line d1 is connected to the first sub-pixel p1; the right side of the second data line d1 is connected to the fourth sub-pixel p1 which is separated from it by the third sub-pixel p1, that is, the right side of the second data line d1 is connected to the fourth sub-pixel p1.

[0051] Optionally, in some embodiments of the present application, in the first direction F1 , the odd-numbered data lines d1 and the even-numbered data lines d1 are configured to have data signals with opposite polarities connected thereto in the same picture frame.

[0052] It can be understood that in the same picture frame, the odd-numbered data lines d1 and the even-numbered data lines d1 are connected to data signals with opposite polarities, so that the display panel 100 achieves double column inversion.

[0053] Double column inversion means that two adjacent columns form a unit column, the polarity of the sub-pixels p1 in the same unit column is the same, and the polarity of the sub-pixels p1 between adjacent unit columns is opposite. Compared with conventional column inversion, the uniformity of the electric field is better, which can effectively suppress the problems of lateral crosstalk and flicker, and the image stability is better than the conventional single column inversion.

[0054] For example, in the same picture frame, the 2n+1th data line d1 receives a data signal of one of positive polarity and negative polarity, and the 2n+2nd data line d1 receives a data signal of the other of positive polarity and negative polarity. Wherein, n is an integer greater than 0, for example, n includes 1, 2, 3, etc.

[0055] Optionally, in some embodiments of the present application, sub-pixels p1 in the same column are configured to emit light of the same color.

[0056] It is understandable that in the prior art quasi-dot inversion or dot inversion driving mode, the shared data line needs to control sub-pixels of different colors, resulting in the coexistence of light-loaded pixels and heavy-loaded pixels with large brightness differences in pure color or dual-mixed color images, which leads to the phenomenon of rough images. For example, in the same column of sub-pixels connected to the same data line, if the sub-pixels of the previous level of the sub-pixels of this level are in a dark state, when charging the sub-pixels of this level, the data signal needs to be slowly pulled up from the low potential of zero grayscale to the set potential. At this time, the charging rate of the sub-pixels of this level is low and the luminous brightness does not reach the set brightness. At this time, the sub-pixels of this level are in an overloaded state.

[0057] The display panel 100 based on the embodiment of the present application adopts a column inversion driving method, and the same data line d1 only charges the sub-pixel p1 emitting the same color when starting each level of scanning line group s10. Therefore, the sub-pixels p1 in the same column are set to emit the same color light, so that when a pure color or dual-mixed color display is performed, the sub-pixel p1 of the previous level of the sub-pixel p1 of this level is in a lit state, so that when charging the sub-pixel p1 of this level, the data signal does not need to be slowly pulled up from the low potential of zero grayscale to the set potential, thereby improving the charging rate and the luminous brightness. At this time, the sub-pixel p1 of this level is in a light-loaded state.

[0058] Therefore, when the display panel 100 of the embodiment of the present application displays a pure color or dual-color mixed image, all lit sub-pixels p1 are in a light-load state, reducing the brightness difference of the lit sub-pixels p1 to improve the problem of image roughness.

[0059] Optionally, in some embodiments of the present application, the plurality of sub-pixels p1 include a first sub-pixel b1, a second sub-pixel g1 and a third sub-pixel r1. The first sub-pixel b1, the second sub-pixel g1 and the third sub-pixel r1 are sequentially arranged cyclically along the first direction F1.

[0060] The first subpixel b1 is configured to emit a first color light, the second subpixel g1 is configured to emit a second color light, and the third subpixel r1 is configured to emit a third color light, and the first color light, the second color light and the third color light have different light colors.

[0061] It can be understood that the first sub-pixel b1 , the second sub-pixel g1 , and the third sub-pixel r1 are sequentially arranged to form a pixel unit, and then a plurality of the pixel units are arranged along the first direction F1 .

[0062] Optionally, the display panel 100 in the embodiment of the present application is described by taking the example that the first sub-pixel b1 emits blue light, the second sub-pixel g1 emits green light, and the third sub-pixel r1 emits red light.

[0063] for example, Figure 3 As shown, when a pure green image is displayed, each column of second sub-pixels g1 is connected to a data line d1, and each column of second sub-pixels g1 is lit. At this time, all second sub-pixels g1 are in a full light load state; Figure 4 As shown, when a red-green mixed color picture is displayed, each column of the second sub-pixel g1 is connected to a corresponding data line d1, and each column of the second sub-pixel g1 is lit, and each column of the third sub-pixel r1 is connected to another data line d1, and each column of the third sub-pixel r1 is lit. At this time, all the second sub-pixels g1 and the third sub-pixels r1 are in a fully light-loaded state.

[0064] Optionally, in some embodiments of the present application, the display panel 100 further includes at least one redundant scan line ds1 and a plurality of redundant sub-pixels dp1 disposed in the non-display area of the display panel 100. The plurality of redundant sub-pixels dp1 are arranged in rows along the first direction F1. In the second direction F2, one redundant sub-pixel dp1 corresponds to a plurality of sub-pixels p1 and is arranged in columns. A redundant scan line ds1 and a scan line s1 form a first scan line group s10. The first scan line group s10 is disposed between a row of redundant sub-pixels dp1 and the first row of sub-pixels p1.

[0065] In the display area AA of the display panel 100, each scan line group s10 is disposed between adjacent two rows of sub-pixels p1.

[0066] It can be understood that in the first-level scan line group s10 in the display panel 100, there is one redundant scan line ds1 and one row of redundant sub-pixels dp1. When starting the first-level scan line group s10, although the redundant scan line ds1 is connected to the signal of the turn-on transistor, the data line d1 does not charge the redundant sub-pixel dp1, while the data line d1 charges one sub-pixel p1 corresponding to the scan line s1. Coupled with the start of the next-level scan line group s10, the edge of the display area AA is a complete straight edge, avoiding the situation of jagged edges and improving the display effect.

[0067] Optionally, in some embodiments of the present application, the plurality of redundant sub-pixels dp1 are arranged in another row of redundant sub-pixels dp1 along the first direction F1. In the second direction F2, there is an interval of the display area AA between the two rows of redundant sub-pixels dp1.

[0068] Another redundant scan line ds1 and a scan line s1 form the last scan line group s10. The last scan line group s10 is disposed between another row of redundant sub-pixels dp1 and the last row of sub-pixels p1.

[0069] It can be understood that in the last-level scan line group s10 in the display panel 100, there is one redundant scan line ds1 and one row of redundant sub-pixels dp1. When starting the last-level scan line group s10, although the redundant scan line ds1 is connected to the signal of the turn-on transistor, the data line d1 does not charge the redundant sub-pixel dp1, while the data line d1 charges one sub-pixel p1 corresponding to the scan line s1. Coupled with the start of the previous-level scan line group s10, the edge of the display area AA is a complete straight edge, avoiding the situation of jagged edges and improving the display effect.

[0070] Optionally, in some embodiments of the present application, each row of sub-pixels p1 includes a plurality of repeating units 10a arranged along the first direction F1, and one repeating unit 10a includes four sub-pixels p1. The first sub-pixel p1 and the fourth sub-pixel p1 are configured to emit the same color light, and three consecutive sub-pixels p1 are configured to emit different color lights.

[0071] Optionally, for example, in a certain repeating unit 10a, the first sub-pixel p1 and the fourth sub-pixel p1 emit blue light, the second sub-pixel p1 emits green light, and the third sub-pixel emits red light, but it is not limited thereto. For example, in another repeating unit 10a, the first sub-pixel p1 and the fourth sub-pixel p1 emit red light, the second sub-pixel p1 emits blue light, and the third sub-pixel p1 emits green light.

[0072] Any one of the scan lines s1 in the odd scan line group s10 is connected to the second sub-pixel p1 and the fourth sub-pixel p1 of all the repeating units 10a in the adjacent row of sub-pixels p1. Any one of the scan lines s1 in the even scan line group s10 is connected to the first sub-pixel p1 and the third sub-pixel p1 of all the repeating units 10a in the adjacent row of sub-pixels p1.

[0073] It can be understood that based on the above connection manner of the scan line s1, the data line d1, and each sub-pixel p1, and the column inversion driving method, all the illuminated sub-pixels p1 are in a full light load state under a pure color or double-color mixing picture, so as to reduce the risk of a rough picture.

[0074] Optionally, please continue to refer to Figure 5 and Figure 6 In some embodiments of the present application, the display panel 100 includes a shielding electrode 11. Each sub-pixel p1 includes a pixel electrode p11. The film layers where the shielding electrode 11, the pixel electrode p11, the scan line s1, and the data line d1 are located are formed in the array substrate 10 of the display panel 100. The shielding electrode 11, the data line d1, and the scan line s1 are respectively arranged in different layers.

[0075] Optionally, the array substrate 10 includes a substrate, the scan line s1 is disposed on the substrate, the data line d1 is disposed on the side of the scan line s1 away from the substrate, and the pixel electrode p11 and the shielding electrode 11 are respectively disposed on the side of the data line d1 away from the substrate.

[0076] Optionally, the pixel electrode p11 and the shielding electrode 11 are arranged in the same layer and have the same material, and the two can be formed by using the same photomask process. In some embodiments, the pixel electrode p11 and the shielding electrode 11 can also be arranged in different layers. For example, the shielding electrode 11 is located on the side of the pixel electrode p11 close to the substrate.

[0077] The shielding electrode 11 is configured to access a common signal. In the display panel 100 viewed from above, the shielding electrode 11 covers the data line d1. Two adjacent shielding electrodes 11 are connected by a connecting trace 12. The scan line group s10 and the connecting trace 12 are disposed between two adjacent rows of pixel electrodes p11, and the connecting trace 12 is disposed on a different layer from the scan line s1.

[0078] A part of the connecting trace 12 extends along the edge of the scan line s1 and covers the edge portion of the scan line s1 close to the pixel electrode p11.

[0079] It can be understood that the shielding electrode 11 covers the data line d1 and accesses the common signal, and a common electrode accessing the same common signal is also provided on the counter substrate, so that the area of the shielding electrode 11 is in a dark state during display, so as to save the portion of the black matrix layer located on the data line d1.

[0080] Secondly, the connecting trace 12 connects the shielding electrode 11, so the connecting trace 12 also accesses the common signal. And the common signal is a low-potential signal. Optionally, the voltage of the common signal is less than 1 volt, for example, it can be 0 volt, 0.1 volt, 0.2 volt or 0.5 volt, etc.

[0081] Based on the common signal being a low-potential signal, the connecting trace 12 is used to cover the edge portion of the scan line s1 close to the pixel electrode p11 to shield the lateral parasitic capacitance between the pixel electrode p11 and the scan line s1, thereby improving the stability of the display screen.

[0082] Optionally, in some embodiments of the present application, in the display panel 100 viewed from above, the connecting trace 12 includes a first shielding portion 121, a first connecting portion 122, and a second connecting portion 123 connected in sequence along the first direction F1. The first shielding portion 121 is connected to a shielding electrode 11, and the second connecting portion 123 is connected to another shielding electrode 11.

[0083] Two scan lines s1 in the scan line group s10 are respectively a first scan line s01 and a second scan line s02. The first shielding portion 121 extends along the edge of the first scan line s01 and covers the edge portion of the first scan line s01 close to the pixel electrode p11. In the second direction F2, the first shielding portion 121 extends toward the side of the adjacent pixel electrode p11 and extends beyond the first scan line s01.

[0084] It can be understood that the first shielding portion 121 is used to shield the edge portion of the first scan line s01 close to the pixel electrode p11 in the upper row and extends beyond the first scan line s01 to improve the shielding effect and further reduce the lateral parasitic capacitance between the first scan line s01 and the pixel electrode p11 in the upper row.

[0085] Optionally, in some embodiments of the present application, the connection trace 12 further includes a second shielding portion 124 and a third connection portion 125 that are connected in sequence along the first direction F1. The second shielding portion 124 and the first shielding portion 121 are connected to the same shielding electrode 11, and the third connection portion 125 and the first connection portion 122 are connected to the same second connection portion 123.

[0086] The second shielding portion 124 extends along the edge of the second scanning line s02 and covers the edge portion of the second scanning line s02 on the side close to the pixel electrode p11. In the second direction F2, the second shielding portion 124 extends toward the side of the adjacent pixel electrode p11 and extends beyond the second scanning line s02.

[0087] It can be understood that the second shielding portion 124 is used to shield the edge portion of the second scanning line s02 on the side close to the pixel electrode p11 in the next row and extends beyond the second scanning line s02 to improve the shielding effect and further reduce the lateral parasitic capacitance between the second scanning line s02 and the pixel electrode p11 in the previous row.

[0088] Secondly, using the second shielding portion 124 and the third connection portion 125 as a whole in parallel between the data line d1 and the second connection portion 123 can reduce the impedance of the connection trace 12, and further reduce the impedance of the entire shielding electrode 11 grid.

[0089] Optionally, in some embodiments of the present application, in the display panel 100 viewed from above, the second connection portion 123 is disposed between the first scanning line s01 and the second scanning line s02.

[0090] It can be understood that in the area of each scanning line group s10, the second connection portion 123 is disposed between the first scanning line s01 and the second scanning line s02 so that the second connection portion 123 avoids the scanning line group s10 and reduces the coupling interference of the scanning line s1 to the common signal.

[0091] Optionally, in some embodiments of the present application, the array substrate 10 further includes a light-shielding layer 13. The light-shielding layer 13 includes spacers (not shown in the figure) and light-shielding bars 131 extending along the first direction F1. The light-shielding bars 131 are configured to shield the area between any two rows of pixel electrodes p11. The spacers are configured to maintain the liquid crystal thickness of the display panel 100. The light-shielding bars 131 and the spacers are integrally formed and made of the same material.

[0092] It can be understood that the light-shielding bars 131 and the spacers are integrally formed and can be formed by the same photomask process. Secondly, setting the horizontal light-shielding bars 131 on the side of the array substrate 10 can enable the counter substrate not to provide a portion corresponding to the scanning line s1 area of the black matrix layer, and improve the accuracy of shielding the scanning line s1 area.

[0093] Optionally, in some embodiments of the present application, the array substrate 10 further includes a plurality of circuits, and each of the circuits is connected to a pixel electrode p11. The circuit includes a first transistor t1, a second transistor t2, and a third transistor t3. The pixel electrode p11 includes a main pixel electrode 101 and a sub-pixel electrode 102.

A main storage capacitor is formed between the main pixel electrode 101 and the common electrode line 151. A sub-storage capacitor is formed between the sub-pixel electrode 102 and the common electrode line 151.

[0095] In each row of pixel electrodes p11, the main pixel electrodes 101 of one pixel electrode p11 and the sub-pixel electrodes 102 of another pixel electrode p11 are alternately arranged along the first direction F1. In the second direction F2, two adjacent circuits are centrally arranged between two adjacent main pixel electrodes 101.

[0096] Optionally, in some embodiments, each data line d1 is connected to the first transistors t1 of two adjacent circuits through a source trace 161. The source trace 161 is arranged between two scanning lines s1 in the scanning line group s10 and avoids the two scanning lines s1 to reduce the coupling interference of the scanning signal on the data signal.

[0097] Optionally, in some embodiments, on one side of the first scanning line s01 close to the source trace 161, it is recessed inward in the direction of the adjacent sub-pixel electrode 102 to form a first recess, so as to increase the distance between the first scanning line s01 and the source trace 161, thereby reducing the interference of the scanning signal on the data signal. On one side of the second scanning line s02 close to the source trace 161, it is recessed inward in the direction of the adjacent sub-pixel electrode 102 to form a second recess, so as to increase the distance between the second scanning line s02 and the source trace 161, thereby reducing the interference of the scanning signal on the data signal.

[0098] Optionally, the first recess and the second recess are arranged opposite to each other with the source trace 161 in between.

[0099] Optionally, in some embodiments, in the display panel 100, the lengths of all the source traces 161 are equal, so that the distances from the data signal on the data line d1 to the pixel electrode p11 are equal, thereby improving the overall luminous uniformity of the sub-pixels p1.

[0100] Optionally, in some embodiments, please refer to Figure 7 , in the first direction F1, the first distance L1 from the pixel electrode p11 to the shielding electrode 11 is greater than or equal to 4 microns to reduce the risk of the shielding electrode 11 interfering with the liquid crystal driving electric field. Optionally, the first distance L1 can be 4 microns, 4.1 microns, 4.3 microns, 4.5 microns, 4.7 microns, 4.9 microns, 5 microns, 5.5 microns, or 6 microns, etc.

[0101] In the first direction F1, the second distance L2 from the common electrode line 151 to the data line d1 is greater than or equal to 4 microns to reduce the risk of the data line d1 interfering with the common signal. Optionally, the second distance L2 can be 4 microns, 4.1 microns, 4.3 microns, 4.5 microns, 4.7 microns, 4.9 microns, 5 microns, 5.5 microns, or 6 microns, etc.

[0102] The overlapping width k1 between the common electrode line 151 and the pixel electrode p11 is between 0.15 microns and 0.45 microns to meet the storage capacitance while increasing the aperture ratio. Optionally, the overlapping width k1 can be 0.15 microns, 0.2 microns, 0.25 microns, 0.3 microns, 0.35 microns, 0.4 microns, or 0.45 microns, etc.

[0103] Optionally, in some embodiments, please refer to Figure 8 , in the second direction F2, the light-shielding bar 131 completely covers the scanning line group s10 and the part covering the common electrode line 151. Among them, in the second direction F2, the width k2 of the part where the common electrode line 151 extends beyond the light-shielding bar 131 is between 2 microns and 4 microns to ensure no light leakage while increasing the aperture ratio. Optionally, the width k2 can be 2 microns, 2.5 microns, 3 microns, 3.5 microns, or 4 microns, etc.

[0104] Optionally, the scanning line s1 and the common electrode line 151 are arranged in the same layer and made of the same material, and the two can be formed by the same photomask process. Secondly, the common signal accessed by the common electrode line 151 and the common signal accessed by the shielding electrode 11 are the same or different.
