[0003] In the Triple Gate product architecture, the pixel unit (Pixel) is placed horizontally, and the vertical space is very small, only one-third of the normal vertical placement of the pixel. As a result, the vertical placement area of ​​the GDL unit is very small, and the horizontal space is very large, resulting in very large left and right borders of the product.

[0004] In order to solve the technical problem of large left and right borders of the product, the prior art considers the left and right interlaced driving mode (interlace input), referring to Figure 1 The left-right interlaced driving mode sets the GDL units corresponding to two adjacent rows of pixels to be arranged in an interlaced manner, thereby increasing the longitudinal placement space of the GDL units.

[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0044] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0045] In order to solve the technical problem in the prior art that the GDL units are arranged in a left-right interlaced driving manner, resulting in horizontal stripes when the LCD product displays a pure color picture, the present application provides a display panel and a display device to minimize the horizontal stripes problem generated by the LCD product when displaying a pure color picture.

[0046] Figure 1 FIG. 1 is a schematic diagram of a display panel using a left-right interlaced driving mode in the prior art. Figure 1 In the prior art, LCD (Liquid Crystal Display) products can be scanned by a drive unit ( Figure 1 The pixel unit is driven by a GDL unit.

[0047] like Figure 1 As shown, the GDL units driving the pixel rows of the same color are placed alternately from left to right. For the first row of pixels, the GDL units input signals from left to right, and the signals fade from right to left. For the fourth row of pixels (with the same color as the first row of pixels), the GDL units input signals from right to left, and the signals fade from left to right.

[0048] If according to Figure 1 If the GDL unit is arranged as shown, then due to the difference in the signal input direction and the fading direction of the pixel rows of the same color, horizontal stripes will be generated when the LCD product displays a pure color picture, affecting the user experience.

[0049] To this end, an embodiment of the present application provides a display panel. Figure 2 A schematic diagram of a display panel provided in an embodiment of the present application, referring to Figure 2, a display panel provided in an embodiment of the present application includes:

[0050] N scanning drive lines 1, a plurality of pixel units 2 and N scanning drive units 3, the scanning drive lines 1 extend in a first direction, the color of the pixel units 2 is a first color, a second color or a third color, the pixel units 2 of the same color are arranged into pixel rows 4 in the first direction, the n-th pixel row 4 is connected to the n-th scanning drive unit 3 through the n-th scanning drive line 1, the n-th scanning drive unit 3 inputs a scanning drive signal to the pixel units 2 on the n-th pixel row 4 through the n-th scanning drive line 1, so as to drive the pixel units 2 to display; wherein N is an integer greater than or equal to 1 and a multiple of 3, and n is an integer greater than or equal to 1 and less than or equal to N;

[0051] In the Display panel:

[0052] The scanning driving unit 3 for driving the pixel row 4 composed of the pixel units 2 of the first color inputs the scanning driving signal along the first input direction, and the scanning driving unit 3 for driving the pixel row 4 composed of the pixel units 2 of the second color and / or the third color also inputs the scanning driving signal along the first input direction.

[0053] Specifically, Figure 2 As shown, the display panel is composed of N scan drive lines 1, multiple pixel units 2 and N scan drive units 3. At the same time, the display panel also includes L data drive lines 5. The N scan drive lines 1 extend along the first direction, and the L data drive lines 5 extend along the second direction; wherein N is an integer greater than or equal to 1 and a multiple of 3, n is an integer greater than or equal to 1 and less than or equal to N, and L is an integer greater than or equal to 1.

[0054] The pixel units 2 in the display panel are of the first color, the second color or the third color, N scanning drive lines 1 and L data drive lines 5 are interlaced, and each pixel unit 2 is arranged in a space formed by the scanning drive lines 1 and the data drive lines 5 interlaced, and the pixel units 2 of the same color are arranged into pixel rows 4 in the first direction. Since the pixel units 2 are of the first color, the second color or the third color, the pixel rows 4 in the display panel are also of three colors. A row of pixel rows 4 inputs a scanning drive signal through a scanning drive line 1, that is, the display panel includes N rows of pixel rows 4, and a column of pixel columns inputs a data drive signal through a data drive line 5, that is, the display panel includes L columns of pixel columns. It can be seen that the display panel is composed of N×L pixel units 2.

[0055] The scan driving unit 3 is used to generate a scan driving signal. The n-th pixel row 4 is connected to the n-th scan driving unit 3 via the n-th scan driving line 1 , and the scan driving signal is input to the corresponding pixel row 4 .

[0056] In the display panel provided in the embodiment of the present application, a scanning driving unit 3 for driving a pixel row 4 composed of pixel units 2 of a first color inputs a scanning driving signal along a first input direction, and a scanning driving unit 3 for driving a pixel row 4 composed of pixel units 2 of a second color and / or a third color also inputs a scanning driving signal along the first input direction.

[0057] Through the technical solution provided by the embodiment of the present application, in the display panel provided by the embodiment of the present application, there will only be one pixel row 4 corresponding to one color (the pixel row 4 composed of the pixel units 2 of the second color or the pixel row 4 composed of the pixel units 2 of the third color) that may input the scan drive signal in different input directions. When the scan drive signals of the pixel rows 4 corresponding to most colors in the display panel do not have input direction differences, it is difficult for the human eye to distinguish the horizontal stripes of a single color, which is reflected in the display screen of the display panel, and the horizontal stripes are very small or cannot be detected at all.

[0058] In the above embodiment, referring to Figure 2 The first direction can be the left-right direction (relative to Figure 2 ), the first input direction is from left to right or from right to left (in Figure 2 (from left to right in the middle).

[0059] In addition, the second direction mentioned in the subsequent embodiments is perpendicular to the first direction, and the second direction may be an up-down direction; the second input direction mentioned in the subsequent embodiments is opposite to the first input direction, and the second input direction may be from right to left or from left to right, whichever is opposite to the first input direction. After the description here, the subsequent embodiments shall be based on this and will not be described separately.

[0060] In order to increase the placement space of the scan drive unit 3, in a feasible embodiment of the present application, in the display panel, the scan drive units 3 for driving the pixel rows 4 composed of the pixel units 2 of the first color are all arranged on one side of the display panel, and the scan drive units 3 input the scan drive signals to the pixel rows 4 composed of the pixel units 2 of the first color along the first input direction; the scan drive units 3 for driving the pixel rows 4 composed of the second color are all arranged on the other side of the display panel, and the scan drive units 3 input the scan drive signals to the pixel rows 4 composed of the pixel units 2 of the second color along the second input direction; two adjacent scan drive units 3 for driving the pixel rows 4 composed of the third color are arranged on different sides of the display panel, and the scan drive units 3 input the scan drive signals to the pixel rows 4 composed of the pixel units 2 of the third color along the first input direction or the second input direction; wherein, the first input direction is opposite to the second input direction.

[0061] Continue to refer to Figure 2In the display panel provided in the embodiment of the present application, the scanning driving units 3 for driving the pixel rows 4 composed of the pixel units 2 of the first color are all arranged on one side of the display panel. Therefore, the scanning driving units 3 can be driven from the first input direction ( Figure 2 The scanning driving units 3 for driving the pixel rows 4 composed of the pixel units 2 of the first color are all arranged on the other side of the display panel. Therefore, the scanning driving units 3 can input the scanning driving signals from the second input direction (from left to right). Figure 2 The scanning driving units 3 for driving the pixel rows 4 composed of the pixel units 2 of the second color are alternately arranged on both sides of the display panel. Therefore, the scanning driving units 3 can input the scanning driving signals to the pixel rows 4 composed of the pixel units 2 of the third color from the first input direction or the second input direction.

[0062] As described in the above-mentioned embodiment, the scanning drive units 3 are arranged alternately as much as possible. On the basis of solving the horizontal stripe problem, the horizontal arrangement space of the scanning drive units 3 is expanded as much as possible. This is reflected in the product, and the left and right borders of the product are reduced.

[0063] Reference Figure 3 In a feasible embodiment of the present application, the first color is red, the second color is green, and the third color is blue. The pixel row 4 formed by the pixel units 2 of the first color is a red pixel row 41, the pixel row 4 formed by the pixel units 2 of the second color is a green pixel row 42, and the pixel row 4 formed by the pixel units 2 of the third color is a blue pixel row 43.

[0064] It can be seen that the pixel unit 2 is a red pixel unit R, a green pixel unit G or a blue pixel unit B, the pixel row 4 formed by the red pixel units R is a red pixel row 41, the pixel row 4 formed by the green pixel units G is a green pixel row 42, and the pixel row 4 formed by the blue pixel units B is a blue pixel row 43.

[0065] In order to ensure the display effect of the display panel, in a feasible embodiment of the present application, continue to refer to Figure 3 The pixel rows 4 are arranged in the second direction into M pixel row sets 6, where M is equal to N / 3, wherein: any pixel row set 6 includes a row of red pixel rows 41, a row of green pixel rows 42 and a row of blue pixel rows 43.

[0066] It can be seen that every three adjacent rows of pixel rows 4 form a pixel row set 6, and a pixel row set 6 fixedly includes a row of red pixel rows 41, a row of green pixel rows 42, and a row of blue pixel rows 43. It can be understood that in this embodiment, it is only necessary to ensure that each pixel row set 6 includes a row of red pixel rows 41, a row of green pixel rows 42, and a row of blue pixel rows 43, and the arrangement order of the pixel rows 4 in the pixel row set 6 is not limited.

[0067] For example, you can Figure 3 As shown, the pixel rows 4 in the first pixel row set 6 are arranged in the order of red pixel row 41-green pixel row 42-blue pixel row 43, and the pixel rows 4 in the second pixel row set 6 are also arranged in the order of red pixel row 41-green pixel row 42-blue pixel row 43. Of course, in other embodiments, the pixel rows 4 in the first pixel row set 6 may be arranged in the order of green pixel row 42-red pixel row 41-blue pixel row 43, and the pixel rows 4 in the second pixel row set 6 may be arranged in the order of red pixel row 41-green pixel row 42-blue pixel row 43.

[0068] In order to further ensure the display effect of the display panel, the pixel rows 4 in each pixel row set 6 are arranged in a specific color sequence. It can be understood that in this embodiment, under the premise of ensuring that each pixel row set 6 includes a row of red pixel rows 41, a row of green pixel rows 42, and a row of blue pixel rows 43, the arrangement sequence of the pixel rows 4 in the pixel row set 6 is limited, but the specific arrangement method of the pixel rows 4 of different colors does not need to be limited.

[0069] For example, you can Figure 3 As shown, the pixel rows 4 in each pixel row set 6 are arranged in the color sequence of red pixel row 41-green pixel row 42-blue pixel row 43. Figure 3 As shown, the pixel rows 4 in each pixel row set 6 are arranged in the color order of green pixel row 42 - red pixel row 41 - blue pixel row 43 , or in the color order of red pixel row 41 - blue pixel row 43 - green pixel row 42 .

[0070] In combination with the above-mentioned embodiment of dividing the pixel row set 6, it can be known that within a pixel row set 6, the scanning drive unit 3 corresponding to the red pixel row 41 can be set on one side of the display panel, the scanning drive unit 3 corresponding to the blue pixel row 43 can be set on the other side of the display panel, and the scanning drive unit 3 corresponding to the green pixel row 42 can be set on any side of the display panel; for two adjacent pixel row sets 6, if the scanning drive unit 3 corresponding to the green pixel row 42 is set on the first side of the display panel in the first pixel row set 6, then the scanning drive unit 3 corresponding to the green pixel row 42 needs to be set on the second side of the display panel in the second pixel row set 6.

[0071] Based on the above embodiment, in a possible implementation scenario, the scanning drive unit 3 corresponding to the green pixel row 42 can be set on the first side (for example, the left side) of the display panel, and the scanning drive unit 3 corresponding to the blue pixel row 43 can be set on the second side (for example, the right side) of the display panel, and the scanning drive unit 3 corresponding to the green pixel row 42 is alternately set on both sides of the display panel. In this implementation scenario, when displaying a red pure color picture, the scanning drive units 3 corresponding to all red pixel rows 41 are input with scanning drive signals from left to right through the scanning drive line 1, and the scanning drive signals are attenuated from right to left after the display is completed. For any red pixel unit R, the scanning drive signal input and attenuation degree are equivalent, so that the red pure color picture is displayed well without horizontal stripes; but when displaying a green pure color picture, since the scanning drive units 3 corresponding to the green pixel rows 42 are alternately set on both sides of the display panel, the scanning drive signal input and attenuation degree of the green pixel units G in the two adjacent green pixel rows 42 are not equivalent (the first row is input from left to right and attenuated from right to left, and the next row is input from right to left and attenuated from left to right), so that horizontal stripes appear when displaying a green pure color picture.

[0072] To this end, since the display panel includes red pixel units R, green pixel units G and blue pixel units B, and since the human eye is least sensitive to blue, the scanning drive units 3 corresponding to the blue pixel rows 43 can be alternately arranged on both sides of the display panel, the scanning drive units 3 corresponding to the green pixel rows 42 can be arranged on the first side of the display panel, and the scanning drive units 3 corresponding to the red pixel rows 41 can be arranged on the second side of the display panel, thereby preventing the horizontal stripes from being distinguished by the human eye, improving the display effect of the display panel, and minimizing the probability of horizontal stripes appearing in pure color images.

[0073] In a feasible embodiment of the present application, in the m-th pixel row set 6, the scan driving unit 3 for driving the red pixel row 41 is arranged on the first side of the display panel, the scan driving unit 3 for driving the green pixel row 42 is arranged on the second side of the display panel, and the scan driving unit 3 for driving the blue pixel row 43 is arranged on the first side of the display panel;

[0074] In the m+1th pixel row set 6, the scanning driving unit 3 for driving the red pixel row 41 is set on the first side of the display panel, the scanning driving unit 3 for driving the green pixel row 42 is set on the second side of the display panel, and the scanning driving unit 3 for driving the blue pixel row 43 is set on the second side of the display panel.

[0075] In a feasible embodiment of the present application, in the m-th pixel row set 6, the scan driving unit 3 for driving the red pixel row 41 is arranged on the first side of the display panel, the scan driving unit 3 for driving the green pixel row 42 is arranged on the second side of the display panel, and the scan driving unit 3 for driving the blue pixel row 43 is arranged on the second side of the display panel;

[0076] In the m+1th pixel row set 6, the scanning driving unit 3 for driving the red pixel row 41 is set on the first side of the display panel, the scanning driving unit 3 for driving the green pixel row 42 is set on the second side of the display panel, and the scanning driving unit 3 for driving the blue pixel row 43 is set on the first side of the display panel.

[0077] In a feasible embodiment of the present application, the pixel unit 2 can be displayed through a 17T1C circuit.

[0078] In a feasible embodiment of the present application, the length of the pixel unit 2 in the first direction is greater than the length of the pixel unit 2 in the second direction.

[0079] Based on the above embodiments of the present application, it can be seen that the display panel provided by the present application has at least the following advantages:

[0080] 1. It can greatly reduce the size of the left and right borders of LCD products.

[0081] 2. It can greatly reduce the probability of horizontal stripes appearing on solid color images.

[0082] Based on the display panel provided by the above embodiment, the scanning drive units 3 of the red pixel row 41 can be placed on the right side, the scanning drive units 3 of the green pixel row 42 can be placed on the left side, and the scanning drive units 3 of the blue pixel row 43 can be placed alternately on the left and right sides. In the display panel with such configuration, for one side, there is only one scanning drive unit 3 for every two pixel rows 4, and the CLK signal of the scanning drive unit 3 is only half of the normal number, such as Figure 4 As shown, CLK1-CLK6 circulate, then CLK1, CLK4, CLK5 on the left, and CLK2, CLK3, CLK6 on the right.

[0083] Reference Figure 5In another feasible embodiment of the present application, following the concept of the above embodiment, in the display panel, the scanning driving line 1 includes a first scanning driving line 11 and a second scanning driving line 12, and the n-th pixel row 4 is connected to the n-th scanning driving unit 3 through the n-th first scanning driving line 11 or the n-th second scanning driving line 12;

[0084] The first end of the nth first scan driving line 111 is connected to the first end of the nth second scan driving line 12, and the second end of the n+1th first scan driving line 11 is connected to the second end of the n+1th second scan driving line 12; wherein the first end of the first scan driving line 11 and the first end of the second scan driving line 12 are located on one side of the display panel, and the second end of the first scan driving line 11 and the second end of the second scan driving line 12 are located on the other side of the display panel;

[0085] The nth scan driving unit 3 is connected to the second end of the first scan driving line 11 , and the (n+3)th scan driving unit 3 is connected to the first end of the second scan driving line 12 .

[0086] Specifically, for any pixel row 4 , a first scanning driving line 11 and a second scanning driving line 12 are disposed thereunder. Therefore, for n pixel rows 4 , there are currently n first scanning driving lines 11 and n second scanning driving lines 12 .

[0087] The first end of the nth first scan driving line 11 is connected to the first end of the nth second scan driving line 12, and the second end of the n+1th first scan driving line 11 is connected to the second end of the n+1th second scan driving line 12; wherein the first end of the first scan driving line 11 and the first end of the second scan driving line 12 are located on one side of the display panel, and the second end of the first scan driving line 11 and the second end of the second scan driving line 12 are located on the other side of the display panel. It can be understood that the above-mentioned first scan driving line 11 and the second scan driving line 12 can be formed by bending the same scan driving line 1.

[0088] The nth scan driving unit 3 is connected to the second end of the first scan driving line 11, and the n+3th scan driving unit 3 is connected to the first end of the second scan driving line 12. Based on the above configuration, for the pixel rows 4 with the same color, the scan driving units 3 corresponding to the two adjacent pixel rows 4 with the same color are connected to the second end of the first scan driving line 11 and the first end of the second scan driving line 12, respectively.

[0089] For example, Figure 5As shown, the display panel is arranged in a sequential cycle of red pixel rows 41-green pixel rows 42-blue pixel rows 43. For the red pixel rows 41, the a-th first scanning drive line 11 and the a-th second scanning drive line 12 are arranged below the a-th red pixel row 41, the a-th red pixel row 41 is connected to the second end of the a-th first scanning drive line 11 (such as the left side), and the a+1-th red pixel row 41 is connected to the first end of the a-th second scanning drive line 12 (such as the right side). At this time, for the a-th red pixel row 41, the scanning drive unit 3 can directly input the scanning drive signal from left to right through the first scanning drive line 11. For the a+1-th red pixel row 41, the scanning drive signal first passes through the second scanning drive line 12, and then passes through the first scanning drive line 11. When the scanning drive signal first passes through the second scanning drive line 12, the scanning drive signal is not actually input. Only when the scanning drive signal passes through the first scanning drive line 11, the scanning drive signal is actually input. Therefore, the scanning drive signal of the a+1-th red pixel row 41 is still input from left to right.

[0090] The blue pixel row 43 is similar to the green pixel row 42 .

[0091] It can be seen that based on the above embodiment, on the one hand, it is ensured that the scanning drive signals of the pixel rows 4 of all colors are input in the same direction; on the other hand, compared with the embodiment of the non-bending scanning drive line 1 described in the above embodiment of the present application, this embodiment further expands the lateral space of the scanning drive unit 3 (because in this embodiment the scanning drive unit 3 always maintains an alternating setting of left-right-left-...), which is reflected in the product, further reducing the product border area.

[0092] Based on the same inventive concept, the present application also provides a display device, referring to Figure 6 The display device includes the display panel provided by any of the above embodiments of the present application. The structure of the display panel has been described in the above embodiments and will not be repeated here. The display device provided by the embodiments of the present application can be any device with a display function, such as a mobile phone, a tablet computer, a laptop computer, an e-book, a television, a smart watch, etc.
