Description

Display panel and display device

[0001] This application claims priority to Chinese patent application No. 202411199478.1, filed on August 29, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of display technology, and more particularly to a display panel and display device. Background Technology

[0003] With the continuous development of liquid crystal display technology, consumers' demand for high quality, high refresh rate and low cost of large-size 4K liquid crystal displays (LCDs) is increasing day by day. At present, the common method is to reduce the manufacturing cost of liquid crystal display panels by using data line sharing (DLS). Specifically, multiple pixels are connected to the same data line by electrical connection lines of different lengths (long and short arm design), and multiple pixels are driven simultaneously by a single data line signal, reducing the number of data lines and driving components such as chip on film (COF), thereby reducing the manufacturing cost of the panel.

[0004] In the existing DLS pixel architecture, since subpixels are usually arranged in the order of red, green and blue subpixels in the horizontal direction, when using double line gate (DLG) technology, which drives two rows of pixels simultaneously in one frame period to achieve a high refresh rate, the shared data line cannot avoid interference between subpixels of different colors when transmitting signals. This interference will lead to the inability to accurately control the display color of each subpixel, resulting in color crosstalk, which ultimately affects the overall display quality of the image.

[0030] This application provides a display panel and a display device. These 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.

[0031] Please refer to Figure 1, which is a schematic diagram of the structure of the display panel provided in an embodiment of this application.

[0032] In one embodiment, the display panel 1 includes, but is not limited to, a liquid crystal display (LCD) panel. The display panel 1 includes an array substrate 11 and a color filter substrate 12 disposed opposite to each other, and a liquid crystal layer (not shown in the figure) located between the array substrate 11 and the color filter substrate 12. The array substrate 11 and the color filter substrate 12 are sealed to form a liquid crystal cell to accommodate the liquid crystal layer.

[0033] The array substrate 11 may include conventional film layers such as a first substrate 111, a first metal layer (not shown in the figure), a first insulating layer (not shown in the figure), a semiconductor layer (not shown in the figure), a second metal layer 112, a second insulating layer 113, and a first electrode layer 114; the first substrate 111 may include one of a rigid substrate or a flexible substrate. When the substrate is a rigid substrate, the material may be metal or glass. When the substrate is a flexible substrate, the material may include at least one of acrylic resin, methacrylic resin, polyisoprene, vinyl resin, epoxy resin, polyurethane-based resin, cellulose resin, siloxane resin, polyimide-based resin, and polyamide-based resin.

[0034] The first metal layer is located on one side of the first substrate 111. The first metal layer may include a gate (not shown in the figure) and multiple scan lines (not shown in the figure); the first insulating layer is located on the side of the first metal layer away from the first substrate 111. The first insulating layer has strong water and oxygen barrier capabilities and insulation capabilities. Its material includes, but is not limited to, silicon oxide, silicon nitride, silicon oxynitride, or their stacks; the second metal layer 112 is located on the side of the first insulating layer away from the first metal layer. The second metal layer 112 may include a source-drain layer (not shown in the figure) and multiple data lines 1121; the first electrode layer 114 may be a pixel electrode layer. The first electrode layer 114 may include multiple pixel electrodes 1141 arranged at intervals.

[0035] The color filter substrate 12 may include a second substrate 121, a color resist layer 122, a black matrix 123, and a second electrode layer (not shown in the figure). The color resist layer 122 is disposed on the side of the second substrate 121 close to the first substrate 111, the black matrix 123 is disposed on the side of the color resist layer 122 away from the second substrate 121, and the second electrode layer is disposed on the side of the black matrix 123 away from the color resist layer 122. The second electrode layer may be a common electrode layer.

[0036] The color resist layer 122 may include multiple color resists 1221 of different colors, including but not limited to red, green, and blue color resists. The color resists 1221 are typically arranged in a specific order to ensure optimal color performance of the display panel 1. The black matrix 123 includes multiple black modules spaced apart, with each black module corresponding to two adjacent color resists 1221 and located between them. The black matrix can block light, preventing crosstalk between the color resists 1221, thereby improving the display effect of the display panel 1.

[0037] The liquid crystal layer comprises a plurality of liquid crystal molecules. When displaying an image, the first electrode layer 114 and the second electrode layer apply an electric field to the liquid crystal layer. By controlling the twisting of the liquid crystal molecules in the liquid crystal layer, the polarization direction of the light from the backlight module is changed, so as to control whether the light intensity is allowed to pass through the liquid crystal cell, thereby displaying the corresponding image.

[0038] It should be noted that the array substrate 11 may include a first substrate 111, a first metal layer, a first insulating layer, a semiconductor layer, a second metal layer 112, and a first electrode layer 114; the color filter substrate 12 may include a second substrate 121, a color resist layer 122, a black matrix 123, and a second electrode layer. These are only used to illustrate the technical solution of this application, and this embodiment does not impose specific limitations on the structure of the display panel 1.

[0039] Please refer to Figures 1, 2, and 3; wherein, Figure 2 is a first equivalent circuit diagram of the pixel structure provided in the embodiment of this application; and Figure 3 is an equivalent circuit diagram of the pixel structure shown in Figure 2 provided in the embodiment of this application when n=3 and m=11.

[0040] In one embodiment, the display panel 1 includes a plurality of sub-pixels 13, a plurality of data lines 1121, and n scan line groups 14; the plurality of sub-pixels 13 are arranged along a first direction X and a second direction Y, and the plurality of sub-pixels 13 include n+1 sub-pixel rows 131 arranged at intervals along the second direction Y, and each sub-pixel row 131 includes m+1 sub-pixels 13 arranged at intervals along the first direction; the plurality of data lines 1121 extend along the second direction Y and are arranged at intervals along the first direction X, one data line 1121 is connected to two columns of sub-pixels 13, and each data line 1121 is disposed between the two columns of sub-pixels 13 to which it is connected; the nth scan line group 14 is disposed between the nth sub-pixel row 131 and the n+1th sub-pixel row 131, and each scan line group 14 includes a first scan line 141 and a second scan line 142, the first scan line 141 and the second scan line 142 extend along the first direction X and are arranged along the second direction Y.

[0041] The first direction X and the second direction Y form a preset angle, where n is a natural number greater than or equal to 2 and m is a natural number greater than or equal to 1. It should be noted that this embodiment uses the first direction as the X direction, the second direction as the Y direction, and the preset angle as a right angle as an example to illustrate the technical solution of this application.

[0042] In this configuration, the odd-numbered sub-pixels 13 of the nth sub-pixel row 131 are connected to the second scan line 142 of the (n-1)th scan line group 14, the even-numbered sub-pixels 13 of the nth sub-pixel row 131 are connected to the first scan line 141 of the nth scan line group 14, and the color of the mth sub-pixel 13 of the nth sub-pixel row 131 is the same as the color of the (m+1)th sub-pixel 13 of the (n-1)th sub-pixel row 131.

[0043] It should be noted that the pixel structure equivalent circuit diagram shown in Figure 3 is an example of the technical solution of this application, with the display panel 1 including 5 sub-pixel rows 131 (L1 to L5), 12 sub-pixel columns 132 (H1 to H12), 6 data lines 1121 (D1 to D6), and 4 scan line groups 14; wherein each sub-pixel row 131 includes 12 sub-pixels 13, and each scan line group 14 includes a first scan line 141 and a second scan line 142, that is, the display panel 1 includes 8 scan lines (G1 to G8).

[0044] It should be noted that with the continuous development of liquid crystal display technology, the method of data line sharing (DLS) is usually adopted to reduce the manufacturing cost of liquid crystal display panels. Please refer to Figure 4, which is the first equivalent circuit diagram of the pixel structure of the display panel in the related technology. The display panel 2 includes multiple scan lines 21 and multiple data lines 22. One data line 22 and two adjacent scan lines 21 form a pixel unit 23. The pixel unit 23 includes two sub-pixels 231. The two sub-pixels 231 are set with one data line 22, and the two sub-pixels 231 are connected to the same data line 22 by electrical connection lines 24 of different lengths (long and short arm design). Multiple sub-pixels 231 are driven simultaneously by a signal of one data line 22, thereby reducing the number of data lines 22 and driving components such as chip on film (COF) and reducing the manufacturing cost of the display panel 2.

[0045] In this embodiment, the display panel 2, which includes 4 sub-pixel rows 2311, 4 data lines (D1 to D4), and 8 scan lines (G1 to G8), is used as an example to illustrate the relevant technologies.

[0046] Currently, a high refresh rate for display panels is typically achieved by simultaneously driving two sub-pixel rows 2311 within one frame period, known as Double Line Gate (DLG). As shown in Figure 4, in the existing DLS pixel architecture, since the sub-pixels 231 in any sub-pixel row 2311 are arranged periodically in the order of red, green, and blue sub-pixels, and the sub-pixels 231 in the same sub-pixel column 2312 have the same color, the data line 22 cannot avoid interference between sub-pixels 231 of different colors when transmitting signals. This interference will lead to an inability to accurately control the display color of each sub-pixel 231. When displaying a solid color image, color crosstalk is likely to occur, ultimately affecting the overall display quality of the image.

[0047] It is understood that this embodiment solves the interference problem of DLG driving mode under the existing DLS pixel framework by designing the arrangement and connection of sub-pixels 13, data lines 1121 and scan lines, and achieves high refresh rate and high quality display effect; at the same time, by optimizing the color arrangement of sub-pixels 13, the interference between sub-pixels 13 of different colors is reduced, ensuring the accurate display color of each sub-pixel 13 and improving the overall image display quality.

[0048] Specifically, since one data line 1121 is connected to two columns of sub-pixels 13, and each data line 1121 is located between the two columns of sub-pixels 13 connected to it; wherein the color of the m-th sub-pixel 13 of the n-th sub-pixel row 131 is the same as the color of the (m+1)-th sub-pixel 13 of the (n-1)-th sub-pixel row 131, such that when the first scan line 141 and the second scan line 142 of any scan line group 14 are simultaneously turned on, one data line 1121 provides a corresponding data voltage. The signal is transmitted to the sub-pixel 13 with the same color, which reduces the signal interference between sub-pixels 13 of different colors. This prevents color mixing when the display panel 1 uses the double refresh rate technology, alleviates the technical problem of color mixing when multiple scan lines are turned on at the same time in the existing pixel architecture, and improves the display quality of the display panel 1. Furthermore, under the DLG driving technology, the two sub-pixel rows 131 are driven at the same time in the same frame period, which can realize the synchronous driving of the two sub-pixel rows 131 without increasing the number of data lines 1121.

[0049] Furthermore, referring to Figures 2 and 3, in the display panel 1, two sub-pixels 13 are configured with one data line 1121, and the two sub-pixels 13 are connected to the same data line 1121 using electrical connection lines 24 of different lengths (long and short arm design). In this embodiment, since one data line 1121 is connected to two columns of sub-pixels 13, and each data line 1121 is located between the two columns of sub-pixels 13 connected to it, the two sub-pixels 13 can be connected to the same data line 1121 using connection lines 15 of the same length (double short arm design), thereby ensuring that the signal transmission time between two adjacent sub-pixels 13 is consistent, reducing signal delay and distortion, and thus ensuring that the signal strength received by each sub-pixel 13 is consistent, thereby improving the display quality of the image. At the same time, the double short arm design simplifies the circuit design, only requiring that all connection lines be of the same length, reducing design complexity and manufacturing difficulty, and improving production efficiency.

[0050] Please continue referring to Figures 2 and 3. In one embodiment, the plurality of sub-pixels 13 include m+1 sub-pixel columns 132 arranged at intervals along the first direction X, each sub-pixel column 132 including n+1 sub-pixels 13; the nth sub-pixel 13 of the mth sub-pixel column 132 is connected to the second scan line 142 of the (n-1)th scan line group 14, and the (n-1)th sub-pixel 13 of the (m+1)th sub-pixel column 132 is connected to the first scan line 141 of the (n-1)th scan line group 14; wherein, the color of the nth sub-pixel 13 of the mth sub-pixel column 132 is the same as the color of the (n-1)th sub-pixel 13 of the (m+1)th sub-pixel column 132.

[0051] It is understood that in this embodiment, the nth sub-pixel 13 of the mth sub-pixel column 132 is connected to the second scan line 142 of the (n-1)th scan line group 14, and the (n-1)th sub-pixel 13 of the (m+1)th sub-pixel column 132 is connected to the first scan line 141 of the (n-1)th scan line group 14; wherein the color of the nth sub-pixel 13 of the mth sub-pixel column 132 is the same as the color of the (n-1)th sub-pixel 13 of the (m+1)th sub-pixel column 132, thereby reducing color crosstalk during the driving process, making the color consistency of the sub-pixels 13 in adjacent columns higher when using DLG driving technology, thereby reducing signal interference between sub-pixels 13 of different colors, and the display panel 1 can achieve a more uniform display effect at a high refresh rate.

[0052] Please refer to Figures 2 and 3. In one embodiment, the first sub-pixel 13 of the m-th sub-pixel column 132 is not connected to the data line 1121, and the first sub-pixel 13 of the m-th sub-pixel column 132 is not connected to the scan line group 14; the (m+1)-th sub-pixel 13 of the (m+1)-th sub-pixel column 132 is not connected to the data line 1121, and the (m+1)-th sub-pixel 13 of the (m+1)-th sub-pixel column 132 is not connected to the scan line group 14; specifically, the first sub-pixel 13 of the m-th sub-pixel column 132 is not connected to either the first scan line 141 or the second scan line 142, and the (m+1)-th sub-pixel 13 of the (m+1)-th sub-pixel column 132 is not connected to either the first scan line 141 or the second scan line 142.

[0053] Furthermore, the even-numbered sub-pixels 13 of the first pixel row are connected to the first scan line 141 of the first scan line group 14, and the odd-numbered sub-pixels 13 of the first sub-pixel row 13 are not connected to the scan line group 14; the odd-numbered sub-pixels 13 of the (n+1)th sub-pixel row 13 are connected to the second scan line 142 of the nth scan line group 14, and the even-numbered sub-pixels 13 of the (n+1)th pixel row are not connected to the scan line group 14.

[0054] Specifically, the sub-pixel column 132 includes a plurality of isolated sub-pixels 1310. In two adjacent sub-pixel columns 132, the first sub-pixel 13 of one sub-pixel column 132 is the isolated sub-pixel 1310, and the (n+1)th sub-pixel 13 of the other sub-pixel column 132 is the isolated sub-pixel 1310.

[0055] In this embodiment, the isolated sub-pixel 1310 may cause inconsistent overall display effects due to the lack of support from adjacent sub-pixels 13 of the same color. For example, referring to Figure 3, in the first sub-pixel column 132 (H1) and the second sub-pixel column 132 (H2), the first sub-pixel 13 of the first sub-pixel column 132 (H1) is a red sub-pixel 13. Since there is no sub-pixel 13 of the same color connected to the same data line 1121, the red sub-pixel 13 may not have sufficient signal support. The fifth sub-pixel 13 of the second sub-pixel column 132 (H2) is a green sub-pixel 13. Since there is no sub-pixel 13 of the same color connected to the same data line 1121, the green sub-pixel 13 may not have sufficient signal support, resulting in an unsatisfactory display effect.

[0056] It is understood that by setting specific sub-pixels 13 not to be connected to the data line 1121 and the scan line, these sub-pixels 13 will not participate in the display and driving process of the image, thus avoiding the problem of uneven driving in the edge area of ​​the display panel 1, thereby improving the consistency and uniformity of the image display.

[0057] It should be noted that the above-mentioned "no sub-pixel 13 of the same color is connected to the same data line 1121" means that there is no sub-pixel 13 in the second sub-pixel column 132 that corresponds to the first sub-pixel 13 in the first sub-pixel column 132, and there is no sub-pixel 13 in the first sub-pixel column 132 that corresponds to the fourth sub-pixel 13 in the second sub-pixel column 132.

[0058] Please refer to Figures 2 and 3. In one embodiment, the display panel 1 includes a first sub-pixel 1311 displaying a first color, a second sub-pixel 1312 displaying a second color, and a third sub-pixel 1313 displaying a third color. The first color, the second color, and the third color are all different. In each sub-pixel row 131 and each sub-pixel column 132, multiple sub-pixels 13 are arranged in a repeating order of the first sub-pixel 1311, the second sub-pixel 1312, and the third sub-pixel 1313. It should be noted that this embodiment uses red as the first color, green as the second color, and blue as the third color as an example to illustrate the technical solution of this application.

[0059] Specifically, the sub-pixels 13 in each row and each column are arranged in the order of red sub-pixels 13, green sub-pixels 13, and blue sub-pixels 13, repeating sequentially. That is, adjacent sub-pixels 13 in the horizontal and vertical directions have different colors, while sub-pixels 13 on a 45° diagonal line have the same color. If the first sub-pixel 13 in the current row is red, then the sub-pixels 13 in the corresponding row are arranged in the order of red sub-pixels 13, green sub-pixels 13, and blue sub-pixels 13, repeating sequentially. For example, in one of the sub-pixels... In row 131, if the first sub-pixel 13 (the first sub-pixel 13) at the beginning of the current row is a green sub-pixel 13, then following the order of red sub-pixel 13, green sub-pixel 13, and blue sub-pixel 13, the next sub-pixel after green sub-pixel 13 should be blue sub-pixel 13, followed by red sub-pixel 13. Therefore, the sub-pixel 13 in the corresponding row will be arranged in the order of green sub-pixel 13, blue sub-pixel 13, and red sub-pixel 13. The arrangement of sub-pixel column 132 is the same, and will not be described in detail here.

[0060] It is understandable that, as shown in Figure 4, in the existing DLS pixel architecture, since the sub-pixels 231 in any sub-pixel row 2311 are arranged periodically in the order of red sub-pixels, green sub-pixels, and blue sub-pixels, the data line 22 cannot avoid interference between sub-pixels 231 of different colors when transmitting signals. In this embodiment, by setting that in each sub-pixel row 131 and each sub-pixel column 132, multiple sub-pixels 13 are arranged in the order of the first sub-pixel 1311, the second sub-pixel 1312, and the third sub-pixel 1313, the interference between sub-pixels 13 of different colors is reduced. Thus, under DLG driving technology, it helps to stably and accurately transmit the signal of each sub-pixel 13, suppress cross-color phenomenon, and improve the accuracy of displayed colors.

[0061] Furthermore, by arranging the sub-pixels 13 in the order of the first color, the second color, and the third color in this embodiment, the color distribution of each sub-pixel row 131 and each sub-pixel column 132 can be made uniform, thereby improving the color uniformity and consistency of the display panel throughout the entire pixel area, making the image display more natural and realistic. Thus, under the DLG driving technology, both a high refresh rate and a good display effect are achieved, making it particularly suitable for display requirements of high resolution and high refresh rate.

[0062] Referring to Figures 1, 2, and 3, in one embodiment, the multiple color resists 1221 are independent of each other, making each color resist 1221 an island-shaped structure. The independent sub-pixel 13 design of the island-shaped color resist 1221 can reduce optical cross-interference and improve image clarity and contrast. At the same time, unlike strip color resists, the island-shaped color resist 1221 does not use a single color on the entire row or column, which reduces the risk of color mixing and improves color purity and accuracy. Furthermore, in DLS technology, the design of the island-shaped color resist 1221 can more precisely control the current of each sub-pixel 13, reducing the problem of color unevenness.

[0063] It should be noted that, please refer to Figures 5 and 6; Figure 5 is a second equivalent circuit diagram of the pixel structure of the display panel in the related art; Figure 6 is a waveform diagram of the data signal and scan signal of the pixel structure in Figure 5; the display panel 3 includes multiple scan lines 31, multiple data lines 32, multiple sub-pixel columns 311 and multiple sub-pixel rows 312; wherein, each sub-pixel column 311 and each sub-pixel row 312 includes multiple sub-pixels 33, and the sub-pixels 33 in the same sub-pixel column 311 have the same color, and the sub-pixels 33 in any sub-pixel row 312 are arranged periodically in the order of red sub-pixels, green sub-pixels and blue sub-pixels; wherein, adjacent two Two scan lines 34 are provided between sub-pixel rows 312. The multiple data lines 32 include multiple first data lines 321 and multiple second data lines 322. One first data line 321 is connected to two sub-pixel columns 311 and is located between the two sub-pixel columns 311 connected to it. One second data line 322 is connected to two sub-pixel columns 311 and is located between the two sub-pixel columns 311 connected to it. The first data line 321 and the second data line 322 are respectively configured with data voltages of opposite polarities. Multiple sub-pixels are driven simultaneously through a data line 33 signal, thereby reducing the number of data lines and driving components such as chip on film (COF) and reducing the manufacturing cost of the display panel.

[0064] It should be noted that this embodiment uses the display panel 3, which includes 4 sub-pixel rows, 6 sub-pixel columns, 3 data lines (D1 to D3), and 8 scan lines (G1 to G8), as an example to illustrate the relevant technologies.

[0065] As shown in Figures 5 and 6, in the display panel 3, by setting the polarity of the driving voltage of the first data line 321 in two adjacent frames to be opposite, and the polarity of the driving voltage of the second data line 322 in two adjacent frames to be opposite, line inversion (N-line) is achieved. The voltage reversal causes the arrangement of liquid crystal molecules to be readjusted in each frame or line, maintaining a stable image display. However, each time the voltage polarity reverses, the driving circuit must handle a large amount of charge redistribution, which consumes additional electrical energy. This reversal process causes a momentary increase in current, thereby increasing power consumption.

[0066] Please refer to Figures 2, 3, and 7; Figure 7 is a waveform diagram of the data signal and scan signal of the pixel structure shown in Figure 2 provided in an embodiment of this application; in one embodiment, the plurality of data lines 1121 include a plurality of first-type data lines 11211 and a plurality of second-type data lines 11212; the plurality of sub-pixels 13 include a plurality of first sub-pixel columns 1321 and a plurality of second sub-pixel columns 1322 spaced apart along the first direction X, two adjacent first sub-pixel columns 1321 are configured and connected to the same first-type data line 11211, and two adjacent second sub-pixel columns 1322 are configured and connected to the same second-type data line 11212; wherein, the first-type data lines 11211 and the second-type data lines 11212 are respectively configured with data voltages of opposite polarities.

[0067] Specifically, multiple first-type data lines 11211 and multiple second-type data lines 11212 are alternately arranged along the first direction X; wherein, a first-type data line 11211 is disposed between two adjacent first sub-pixel columns 1321, and a sub-pixel 13 of any first sub-pixel column 1321 is connected to the first-type data line 11211; a second-type data line 11212 is disposed between two adjacent second sub-pixel columns 1322, and a sub-pixel 13 of any second sub-pixel column 1322 is connected to the second-type data line 11212.

[0068] It is understood that in this embodiment, by sequentially and alternately arranging multiple first-type data lines 11211 and multiple second-type data lines 11212 along the first direction X, and configuring them with data voltages of opposite polarities, the voltages of opposite polarities will cancel out some interference signals when transmitting signals, thereby improving the integrity and stability of signal transmission. This helps to provide higher display quality and reduce color distortion and crosstalk.

[0069] Furthermore, as shown in Figure 7, the polarity of the driving voltage of the first type of data line 11211 in two adjacent frames is the same; the polarity of the driving voltage of the second type of data line 11212 in two adjacent frames is the same; wherein, the first type of data line 11211 and the second type of data line 11212 are respectively configured to transmit data voltages of equal magnitude.

[0070] It is understood that the first type of data line 11211 and the second type of data line 11212 are respectively configured to transmit data voltages of equal magnitude, thereby reducing the charge redistribution process. Compared with the row inversion (N-line) technology, the design provided in this embodiment reduces the additional power consumption caused by charge redistribution. At the same time, the column inversion technology is adopted to invert the voltage polarity of the sub-pixels 13 in adjacent columns, keeping the polarity of the data line 1121 in adjacent frames consistent, making the driving of the display panel more stable, thereby providing a more consistent display effect.

[0071] It should be noted that, as can be seen from the above, this embodiment can effectively reduce electric field interference between sub-pixels 13 by designing the arrangement and connection of sub-pixels 13, data lines 1121 and scan lines, thereby reducing crosstalk. Furthermore, by alternately setting the first type of data lines 11211 and the second type of data lines 11212 to maintain the same driving voltage polarity in adjacent frames, this arrangement further balances the electric field distribution of adjacent sub-pixels 13, thereby improving the color consistency of the entire panel.
