Abstract
Description
Technical Field
[0001] This application relates to the field of display technology, specifically to a display panel and a display device. Background Technology
[0002] Data line sharing (DLS) technology is often used to reduce the cost of display panels. In traditional liquid crystal display devices, each sub-pixel is controlled by one data line and one gate scan line. In the pixel array of the DLS architecture, two adjacent columns of sub-pixels share one data line, which halves the data line data of the display device.
[0003] In related technologies, in order to reduce the risk of crosstalk, a dot-reversal driving method is adopted. This causes some sub-pixels in the same column to be connected to the data line through the long arm, while another part of the sub-pixels in the same column is connected to the data line through the short arm. Due to the different impedances of the long and short walls, the charging time of sub-pixel columns of the same color will be different, resulting in uneven light emission of sub-pixels in the same color sub-pixel column.

[0034] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific implementation methods described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, the embodiments can be combined with each other but will not be described in detail one by one. Unless otherwise stated, the directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device; the terms "first," "second," "third," etc. are only used as markings and do not impose numerical requirements or establish a sequence.
[0035] This application provides a display panel and a display device, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.
[0036] exist Figure 1 and Figure 2 In the plan view, the first direction F1 can be a direction parallel to one side of the display panel 100, and for example, it can be the horizontal direction of the display panel 100. The second direction F2 can be a direction parallel to the other side of the display panel 100 in the plan view, and it can be the vertical direction of the display panel 100.
[0037] The display panel 100 is a liquid crystal display panel. The display panel 100 includes multiple data lines d1, multiple scan lines s1, and multiple sub-pixels p1. Two adjacent scan lines s1 form a scan line group s10. The multiple scan lines s1 and multiple data lines d1 are intersected to form multiple pixel areas x1.
[0038] Within a pixel region x1, two sub-pixels p1 are correspondingly set. Multiple sub-pixels p1 are arranged along a first direction F1 to form a sub-pixel row ph1. Multiple sub-pixels p1 are arranged along a second direction F2 to form a sub-pixel column pv1. A scan line group s10 is set between two adjacent sub-pixel rows ph1, and each scan line s1 connects a portion of the sub-pixels p1 in a sub-pixel row ph1.
[0039] Optionally, the second direction F2 intersects the first direction F1. The first direction F1 is parallel to the extension direction of the scan line s1, and the second direction F2 is parallel to the extension direction of the data line d1, but is not limited thereto.
[0040] It should be understood that the sub-pixel p1 set in the display area AA includes an overlapping pixel electrode and a color filter block. The pixel electrode is set on the array substrate, and the color filter block can be set on the array substrate or on the opposing substrate.
[0041] Optionally, the color filter block includes a red block, a green block, and a blue block, wherein a sub-pixel p1 with a red block is configured to emit red light, a sub-pixel p1 with a green block is configured to emit green light, and a sub-pixel p1 with a blue block is configured to emit blue light.
[0042] Secondly, the display panel 100 also includes a redundant sub-pixel dp1 disposed in the non-display area NA, the redundant sub-pixel dp1 being configured not to emit light. The redundant sub-pixel dp1 includes redundant pixel electrodes and redundant color filter blocks disposed in overlapping layers, wherein the redundant pixel electrodes and pixel electrodes are disposed in the same layer, and the redundant color filter blocks and color filter blocks are disposed in the same layer.
[0043] In some embodiments of the present application, in the display panel 100, on the first direction F1, one side of each data line d1 is connected to a sub-pixel column pv1 adjacent to it, and the other side of each data line d1 is connected to a sub-pixel column pv1 spaced apart from it by a sub-pixel column pv1.
[0044] The display panel 100 also includes a first connection structure 11 and a second connection structure 12, wherein the length of the first connection structure 11 is less than the length of the second connection structure 12. Each data line d1 and its adjacent sub-pixel p1 of a sub-pixel column pv1 are connected through the first connection structure 11. Each data line d1 and its adjacent sub-pixel column pv1 of a sub-pixel p1 are connected through the second connection structure 12.
[0045] It is understandable that the longer the connection structure, the longer the time it takes for the data signal to be written to the sub-pixel p1, and the greater the attenuation of the data signal, resulting in less sufficient charging of the sub-pixel p1. Therefore, a uniform connection structure length can reduce the charging difference between sub-pixels p1 in the same sub-pixel column pv1. Thus, the first type of sub-pixel column pv1 is connected to the corresponding data line d1 through a shorter first connection structure 11, and the second type of sub-pixel column pv1 is connected to the corresponding data line d1 through a longer second connection structure 12, so that the degree of charging of all sub-pixels p1 in each sub-pixel column pv1 tends to be the same, improving the light emission uniformity of the same sub-pixel column pv1.
[0046] Optionally, in some embodiments of this application, the first connection structure 11 includes a first trace 111, a first transistor t1, and a second trace 112. One end of the first trace 111 is connected to the data line d1, and the other end of the first trace 111 is connected to one end of the first transistor t1. One end of the second trace 112 is connected to the other end of the first transistor t1, and the other end of the second trace 112 is connected to the pixel electrode of the sub-pixel p1.
[0047] The second connection structure 12 includes a third trace 121, a second transistor t2, and a fourth trace 122. One end of the third trace 121 is connected to the data line d1, and the other end of the third trace 121 is connected to one end of the second transistor t2. One end of the fourth trace 122 is connected to the other end of the second transistor t2, and the other end of the fourth trace 122 is connected to the pixel electrode of the sub-pixel p1.
[0048] The total length of the first trace 111 and the second trace 112 is less than the total length of the third trace 121 and the fourth trace 122.
[0049] Optionally, in some embodiments, the length of the first trace 111 is equal to the length of the third trace 121, and the length of the second trace 112 is less than the length of the fourth trace 122.
[0050] Optionally, in some embodiments, the length of the first trace 111 may be less than the length of the third trace 121, and the length of the second trace 112 may be equal to the length of the fourth trace 122.
[0051] Optionally, in some embodiments, the length of the first trace 111 may be less than the length of the third trace 121, and the length of the second trace 112 may be less than the length of the fourth trace 122.
[0052] Optionally, in some embodiments, the second transistor t2 of the second connection structure 12 is disposed between two adjacent sub-pixel columns pv1 to avoid transistors clustering at the intersection of data line d1 and scan line s1, which would require a wider black matrix at that location, while the black matrix in other areas would be narrower, resulting in uneven light output. Therefore, the first transistor t1 is disposed at the intersection of data line d1 and scan line s1, and the second transistor t2 is disposed between two adjacent sub-pixel columns pv1 to balance the width of the black matrix layer and provide uniform light output of the display panel 100.
[0053] Optionally, in some embodiments of this application, pixel region x1 includes a first pixel region x11 and a second pixel region x12. In the first direction F1, the first pixel region x11 and the second pixel region x12 are arranged alternately. In each column of the first pixel region x11, any one of the two sub-pixel columns pv1 is connected to a data line d1 separated from it by a sub-pixel column pv1 via a second connection structure 12. In each column of the second pixel region x12, any one of the two sub-pixel columns pv1 is connected to an adjacent data line d1 via a first connection structure 11.
[0054] It is understandable that the first pixel area x11 is connected to the sub-pixel p1 through the second connection structure 12, and the second pixel area x12 is connected to the sub-pixel p1 through the first connection structure 11. The first pixel area x11 and the second pixel area x12 are alternately set in the first direction F1, so that the overall layout of the connection structure tends to be balanced, thereby improving the uniformity of the overall light emission.
[0055] Optionally, in some embodiments of this application, the plurality of sub-pixel columns pv1 include a first sub-pixel column B1, a second sub-pixel column G1, and a third sub-pixel column R1. The first sub-pixel column B1, the second sub-pixel column G1, and the third sub-pixel column R1 are arranged sequentially and cyclically along a first direction F1.
[0056] In other words, the first sub-pixel column B1, the second sub-pixel column G1 and the third sub-pixel column R1 form a pixel unit, and multiple identical pixel units are arranged along the first direction F1.
[0057] The first sub-pixel column B1 is configured to emit a first color light, the second sub-pixel column G1 is configured to emit a second color light, and the third sub-pixel column R1 is configured to emit a third color light. The first color light, the second color light, and the third color light are of different colors.
[0058] Optional, in Figure 1 The example shown is that all sub-pixels p1 of the first sub-pixel column B1 emit blue light, all sub-pixels p1 of the second sub-pixel column G1 emit green light, and all sub-pixels p1 of the third sub-pixel column R1 emit red light, but it is not limited to this.
[0059] The display panel 100 includes a plurality of first repeating units 10a, which are arranged along a first direction F1. Each of the first repeating units 10a has four first sub-pixel columns B1, G1, and G1, and four third sub-pixel columns.
[0060] In other words, each first repeating unit 10a includes 4 pixel units.
[0061] Specifically, the first and fourth first sub-pixel columns B1 are connected to their corresponding data lines d1 via the second connection structure 12, and the second and third first sub-pixel columns B1 are connected to their corresponding data lines d1 via the first connection structure 11. The first and second second sub-pixel columns G1 are connected to their corresponding data lines d1 via the second connection structure 12, and the third and fourth second sub-pixel columns G1 are connected to their corresponding data lines d1 via the first connection structure 11. The first and fourth third sub-pixel columns R1 are connected to their corresponding data lines d1 via the first connection structure 11, and the second and third third sub-pixel columns R1 are connected to their corresponding data lines d1 via the second connection structure 12.
[0062] It is understandable that the connection structure arrangement of the first repeating unit 10a, combined with the sub-pixel column pv1 that emits different colors of light, makes the brightness of the three colors of light in the area of the first repeating unit 10a tend to be balanced, thereby improving the light emission uniformity of the display panel 100.
[0063] It should also be noted that data line sharing (DLS) technology is commonly used to reduce the cost of display panels. In traditional LCD devices, each sub-pixel is controlled by one data line and one gate scan line. In the DLS architecture, adjacent columns of sub-pixels share one data line, halving the number of data lines in the display device, but doubling the number of gate scan lines, resulting in a halving of pixel charging time. Currently, one common technique for improving refresh rates is to scan two rows of pixels simultaneously, which can double the refresh rate. However, the inventors of this application have discovered that, based on the current DLS architecture, due to the limitations of the pixel array, when two scan lines are used simultaneously, the data lines will overlap with sub-pixels of different colors, thus making it impossible to apply the dual-scan-line technology to improve the refresh rate.
[0064] The display panel 100 of the embodiments of this application improves the connection architecture of the data line d1 and the sub-pixel p1 to adapt to the dual-scan line technology, thereby improving the refresh rate of the pixel array of the DLS architecture.
[0065] Optionally, in some embodiments of this application, in the first direction F1, odd-numbered data lines d1 and even-numbered data lines d1 are configured such that the polarities of the data signals accessed in the same frame are opposite. The display panel 100 is configured to activate any one scan line group s10, and each data line d1 charges only the sub-pixel p1 that emits light of the same color.
[0066] It is understandable that, based on the fact that when the scan line group s10 is started, the two scan lines s1 are started at the same time, so each data line d1 can charge the two sub-pixels p1 that emit the same color light at the same time, thereby improving the refresh rate.
[0067] Optionally, in some embodiments of this 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 NA of the display panel 100. The plurality of redundant sub-pixels dp1 are arranged along a first direction F1 to form a redundant sub-pixel row dh1. In the second direction F2, a redundant sub-pixel dp1 is disposed side by side with a sub-pixel column pv1, and a redundant scan line ds1 and a scan line s1 form a first scan line group s10, which is disposed between the redundant sub-pixel row dh1 and the sub-pixel row ph1.
[0068] In the display area of the display panel 100, each scan line group s10 is set between two adjacent sub-pixel rows ph1.
[0069] It is understandable that the first-level scan line group s10 in the display panel 100 is equipped with a redundant scan line ds1 and a redundant sub-pixel row dh1. When the first-level scan line group s10 is started, although the redundant scan line ds1 is connected to the signal to turn on the transistor, the data line d1 will not charge the redundant sub-pixel dp1. Instead, the data line d1 will charge a sub-pixel p1 corresponding to the scan line s1. Combined 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 jagged edge and improving the display effect.
[0070] Optionally, in some embodiments of this application, multiple redundant sub-pixels dp1 are arranged along a first direction F1 to form another redundant sub-pixel row dh1, and a display area AA is spaced between the two redundant sub-pixel rows dh1 in a second direction F2.
[0071] Another redundant scan line ds1 and a scan line s1 form the last scan line group s10, which is located between the redundant sub-pixel line dh1 and the sub-pixel line ph1.
[0072] It is understandable that the last-level scan line group s10 in the display panel 100 is equipped with a redundant scan line ds1 and a redundant sub-pixel row dh1. When the last-level scan line group s10 is activated, although the redundant scan line ds1 is connected to the signal to turn on the transistor, the data line d1 will not charge the redundant sub-pixel dp1. Instead, the data line d1 will charge a sub-pixel p1 corresponding to the scan line s1. Combined with the activation of the previous-level scan line group s10, the edge of the display area AA is a complete straight edge, avoiding the jagged edge and improving the display effect.
[0073] Optionally, in some embodiments of this application, each sub-pixel row ph1 includes a plurality of second repeating units 10b arranged along the first direction F1. A second repeating unit 10b includes 4 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 colors of light.
[0074] Optionally, for example, in a certain second repeating unit 10b, 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 not limited to this. For example, in another second repeating unit 10b, 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 emits green light.
[0075] Any scan line s1 in an odd-numbered scan line group s10 connects to the second and third sub-pixels p1 of all second repeating units 10b in a neighboring sub-pixel row ph1. Any scan line s1 in an even-numbered scan line group s10 connects to the first and fourth sub-pixels p1 of all second repeating units 10b in a neighboring sub-pixel row ph1.
[0076] Understandably, based on the connection method of the scan line s1, data line d1 and each sub-pixel p1, the polarity of the odd-numbered sub-pixel column pv1 and the even-numbered sub-pixel column pv1 are opposite in the same frame, thereby achieving column inversion. This ensures that all lit sub-pixels p1 are in a fully light-load state in a solid color or dual-color mixed color image, reducing the risk of image roughness.
[0077] It's important to understand that in existing dot-inversion or dot-inversion driving methods, the shared data line needs to control sub-pixels of different colors. This results in the coexistence of lightly loaded and heavily loaded pixels with significant brightness differences in both solid color and dual-color mixed-color images, leading to image graininess. For example, in the same column of sub-pixels connected to the same data line, if the previous level sub-pixel is dark, when charging this level sub-pixel, the data signal needs to be gradually pulled up from a low potential of zero grayscale to a set potential. At this time, the charging rate of this level sub-pixel is low, and its brightness does not reach the set brightness; thus, this level sub-pixel is in a heavily loaded state.
[0078] The display panel 100 based on the embodiment of this application adopts a column inversion driving method, and the same data line d1 charges only the sub-pixel p1 that emits the same color when starting each level scan line group s10. Therefore, the sub-pixels p1 in the same column are set to emit the same color light, so that when performing pure color or dual color mixing display, the previous level sub-pixel p1 of this level sub-pixel p1 is lit up. 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 gray level to the set potential, thereby improving the charging rate and light emission brightness. At this time, the sub-pixel p1 of this level is in a light load state.
[0079] Figure 3 The diagram shown is a different structural schematic of the display panel 100 according to an embodiment of this application. Figure 3 In this document, parts that differ from the embodiments described above will be described to avoid redundancy.
[0080] It should be noted that, Figure 3 Corresponding embodiments and Figure 1 The only difference between the corresponding embodiments is the driving method. Figure 3 The corresponding embodiment of the display panel 100 is driven by dot reversal, which can better shorten the polarity repetition cycle and reduce the risk of crosstalk.
[0081] Reference Figure 3 In some embodiments of this application, among multiple scan lines s1, every four consecutive scan lines s1 constitute a scan cycle unit, and the display panel 100 is configured to start the scan lines s1 one by one.
[0082] The display panel 100 is configured such that, in any of the scan cycle units, when the first and second scan lines s1 are activated, the polarity of the data signals connected to the same data line d1 is the same, and the polarity of the data signals connected to odd-numbered data lines d1 and even-numbered data lines d1 is opposite; when the third and fourth scan lines s1 are activated, the polarity of the data signals connected to the same data line d1 is the same, and the polarity of the data signals connected to odd-numbered data lines d1 and even-numbered data lines d1 is opposite; and within the same data line d1, the polarity of the data signals connected when the first and second scan lines s1 are activated is opposite to the polarity of the data signals connected when the third and fourth scan lines s1 are activated.
[0083] It should be noted that the scanning cycle unit does not include the redundant sub-pixel row dh1 corresponding to the redundant scan line ds1.
[0084] It is understandable that, within the same frame, the polarity of the data signal switched by data line d1 in each scan cycle unit is consistent. For example, if the polarity of the data signal of the second data line d1 corresponding to the four scan lines s1 in the first scan cycle unit is negative-negative-positive-positive, then the polarity of the signal connected by the second data line d1 in the next scan cycle unit will still be negative-negative-positive-positive.
[0085] For example, in each scan cycle unit, when the first and second scan lines s1 are started, the odd-numbered data lines d1 are connected to the positive polarity data signal, and the even-numbered data lines d1 are connected to the negative polarity data signal; when the third and fourth scan lines s1 are started, the odd-numbered data lines d1 are connected to the negative polarity data signal, and the even-numbered data lines d1 are connected to the positive polarity data signal.
[0086] Of course, in some embodiments, in each scan cycle unit, when the first and second scan lines s1 are started, the odd-numbered data lines d1 are connected to the negative polarity data signal, and the even-numbered data lines d1 are connected to the positive polarity data signal; when the third and fourth scan lines s1 are started, the odd-numbered data lines d1 are connected to the positive polarity data signal, and the even-numbered data lines d1 are connected to the negative polarity data signal.
[0087] Please refer to Figure 4 Accordingly, this application also provides a display device 1000, which includes a display panel 100 as described in any of the above embodiments.
[0088] It should be noted that the structure of the display panel 100 of the display device 1000 in this application embodiment is similar to or the same as the structure of the display panel 100 of any of the above embodiments. For details, please refer to... Figures 1 to 3 The explanation is already given, so it will not be repeated here.
[0089] Display device 1000 can be applied to and used in a variety of products, including, for example, televisions, laptops, monitors, billboards, Internet of Things devices, and portable electronic devices including mobile phones, smartphones, tablet computers, mobile communication terminals, electronic notebooks, e-books, portable multimedia players, navigation devices, and ultra-mobile personal computers.
[0090] Furthermore, the display device 1000 according to some embodiments can be applied to wearable devices and can be used within wearable devices, including smartwatches, watch phones, glasses-type displays, and head-mounted displays. Additionally, according to some embodiments, the display device 1000 can be applied to instrument panels for automobiles, displays in central dashboards or central information displays arranged on instrument panels, interior mirror displays replacing side mirrors in automobiles, and displays for entertainment systems arranged on the back of the front seats for rear-seat passengers in automobiles.
[0091] In this embodiment of the display device 1000, in the first direction F1, each data line d1 is configured such that one side is connected to an adjacent sub-pixel column pv1, and the other side of each data line d1 is connected to a sub-pixel column pv1 spaced apart from it by one sub-pixel column pv1. Specifically, the display panel 100 further includes a first connection structure and a second connection structure. The length of the first connection structure 11 is less than the length of the second connection structure 12. Each data line d1 and the sub-pixel of its adjacent sub-pixel column pv1 are connected through the first connection structure 11, and each data line d1 and the sub-pixel of its spaced-apart sub-pixel column pv1 are connected through the second connection structure 12.
[0092] It is understandable that the longer the connection structure, the longer the time it takes for the data signal to be written to the sub-pixel p1, and the greater the attenuation of the data signal, resulting in less sufficient charging of the sub-pixel p1. Therefore, a uniform connection structure length can reduce the charging difference between sub-pixels p1 in the same sub-pixel column pv1. Thus, the first type of sub-pixel column pv1 is connected to the corresponding data line d1 through a shorter first connection structure 11, and the second type of sub-pixel column pv1 is connected to the corresponding data line d1 through a longer second connection structure 12, so that the degree of charging of all sub-pixels p1 in each sub-pixel column pv1 tends to be the same, improving the light emission uniformity of the same sub-pixel column pv1.
[0093] The above provides a detailed description of a display panel and display device provided in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
