Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display, in particular to a display panel and a display device. BACKGROUND

[0002] The existing LCD product often uses a source driving circuit (GDL) to replace part of the Gate IC function when the Gate IC is not used.

[0003] Under the Triple Gate product architecture, the pixel units (Pixels) are placed horizontally, and the vertical space is very small, only one third of the normal vertically placed Pixels, which results in a very small vertical space for the GDL unit and a very large horizontal space, resulting in a very large left and right frame of the product.

[0004] To solve the technical problem of a large left and right frame of the product, the prior art considers a left and right interlaced driving mode (interlace input), referring to Figure 1 The left and right interlaced driving mode sets the GDL units corresponding to the adjacent two rows of pixel rows to be staggered, thereby increasing the vertical space for the GDL unit.

[0005] However, arranging the GDL units in the left and right interlaced driving mode results in the direction of the input signals of the GDL units being completely opposite for the pixel rows of the same color, which causes the LCD product to have horizontal lines when displaying a pure color picture.

DETAILED DESCRIPTION

[0043] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the 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 of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0044] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplification, the components and arrangements of specific examples are described in the following. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to numbers and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or arrangements discussed.

[0045] In order to solve the technical problem that the LCD product displays horizontal lines when displaying a pure color picture due to the arrangement of GDL units in the left-right interlaced driving mode in the prior art, the present application provides a display panel and a display device, which can reduce the horizontal line problem of the LCD product as much as possible when displaying a pure color picture.

[0046] Figure 1 The structural schematic diagram of the display panel in the prior art is shown in Figure 1 In the prior art, the LCD (Liquid Crystal Display) product can realize the driving of the pixel unit through the scanning driving unit (GDL unit in Figure 1 ).

[0047] As shown in Figure 1 , the GDL units driving the pixel rows of the same color are placed in the left-right interlaced mode. For the first pixel row, the GDL unit inputs the signal from left to right, and the signal decays from right to left. For the fourth pixel row (the color of which is the same as that of the first pixel row), the GDL unit inputs the signal from right to left, and the signal decays from left to right.

[0048] If the GDL units are arranged as shown in Figure 1 , since there is a difference between the signal input direction and the decay direction of the pixel rows of the same color, the LCD product displays horizontal lines when displaying a pure color picture, which affects the user experience.

[0049] Therefore, the embodiments of the present application provide a display panel, Figure 2 The structural schematic diagram of the display panel provided by the embodiments of the present application is shown in Figure 2The display panel provided by the embodiment of the present application comprises:

[0050] N scanning driving lines 1, a plurality of pixel units 2 and N scanning driving units 3, the scanning driving lines 1 extend in a first direction, the pixel units 2 are of 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, an nth pixel row 4 is connected with an nth scanning driving unit 3 through an nth scanning driving line 1, and the nth scanning driving unit 3 inputs a scanning driving signal to the pixel units 2 on the nth pixel row 4 through the nth scanning driving 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 units 3 for driving the pixel rows 4 composed of the pixel units 2 of the first color input the scanning driving signal in a first input direction, and the scanning driving units 3 for driving the pixel rows 4 composed of the pixel units 2 of the second color and / or the third color also input the scanning driving signal in the first input direction.

[0053] Specifically, as shown in the figure, Figure 2 the display panel is composed of N scanning driving lines 1, a plurality of pixel units 2 and N scanning driving units 3, and the display panel further comprises L data driving lines 5, the N scanning driving lines 1 all extend in the first direction, and the L data driving lines 5 all extend in a 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, the N scanning driving lines 1 and the L data driving lines 5 are interlaced with each other, each pixel unit 2 is arranged in a space formed by the interlaced scanning driving lines 1 and data driving lines 5, the pixel units 2 of the same color are arranged into pixel rows 4 in the first direction, and 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 the three colors. One pixel row 4 inputs a scanning driving signal through one scanning driving line 1, that is, the display panel comprises N pixel rows 4, and one pixel column inputs a data driving signal through one data driving line 5, that is, the display panel comprises L pixel columns, and it can be seen that the display panel is composed of N×L pixel units 2.

[0055] The scanning driving units 3 are used for forming scanning driving signals, and an nth pixel row 4 is connected with an nth scanning driving unit 3 through an nth scanning driving line 1, so as to input the scanning driving signal into the corresponding pixel row 4.

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

[0057] Through the technical solution provided in this application embodiment, in the display panel provided in this application embodiment, only one color-corresponding pixel row 4 (pixel row 4 composed of pixel units 2 of the second color or pixel row 4 composed of pixel units 2 of the third color) may receive scan drive signals with different input directions. When the scan drive signals of most color-corresponding pixel rows 4 in the display panel do not show differences in input direction, the human eye can hardly distinguish the horizontal stripes appearing in a single color. As a result, the horizontal stripes are negligible or completely imperceptible on the display screen.

[0058] In the above embodiments, reference is made to Figure 2 The first direction can be left or right (relative). Figure 2 In other words, the first input direction is either from left to right or from right to left (in...). Figure 2 (The middle direction is from left to right).

[0059] Furthermore, in subsequent embodiments, the second direction mentioned is perpendicular to the first direction, and the second direction can be up or down; in subsequent embodiments, the second input direction mentioned is opposite to the first input direction, and the second input direction can be from right to left or from left to right, as long as it is opposite to the first input direction. After this explanation, subsequent embodiments will follow this principle and will not be described separately.

[0060] To increase the placement space of the scanning drive unit 3, in a feasible embodiment of this application, the scanning drive units 3 for driving the pixel row 4 composed of pixel units 2 of the first color are all disposed on one side of the display panel, and the scanning drive units 3 input scanning drive signals to the pixel row 4 composed of pixel units 2 of the first color along the first input direction; the scanning drive units 3 for driving the pixel row 4 composed of the second color are all disposed on the other side of the display panel, and the scanning drive units 3 input scanning drive signals to the pixel row 4 composed of pixel units 2 of the second color along the second input direction; two adjacent scanning drive units 3 for driving the pixel row 4 composed of the third color are disposed on different sides of the display panel, and the scanning drive units 3 input scanning drive signals to the pixel row 4 composed of 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 embodiments of the present application, the scan 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, so that the scan driving units 3 can input scan driving signals to the pixel rows 4 composed of the pixel units 2 of the first color from the first input direction (from left to right). Figure 2 The scan driving units 3 for driving the pixel rows 4 composed of the pixel units 2 of the second color are all arranged on the other side of the display panel, so that the scan driving units 3 can input scan driving signals to the pixel rows 4 composed of the pixel units 2 of the second color from the second input direction (from right to left). Figure 3 The scan driving units 3 for driving the pixel rows 4 composed of the pixel units 2 of the third color are alternately arranged on the two sides of the display panel, so that the scan driving units 3 can input scan 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] The arrangement mode of the scan driving units 3 as described in the above embodiments alternately places the scan driving units 3 as much as possible, expands the horizontal arrangement space of the scan driving units 3 as much as possible on the basis of solving the horizontal stripe problem, and reflects on the product, i.e., the left and right borders of the product are reduced.

[0063] Referring to 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 rows 4 arranged by the pixel units 2 of the first color are red pixel rows 41, the pixel rows 4 arranged by the pixel units 2 of the second color are green pixel rows 42, and the pixel rows 4 arranged by the pixel units 2 of the third color are blue pixel rows 43.

[0064] It can be seen that the pixel units 2 are red pixel units R, green pixel units G or blue pixel units B. The pixel rows 4 arranged by the red pixel units R are red pixel rows 41, the pixel rows 4 arranged by the green pixel units G are green pixel rows 42, and the pixel rows 4 arranged by the blue pixel units B are blue pixel rows 43.

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

[0066] It can be seen that each three adjacent pixel rows 4 form a pixel row set 6, and each pixel row set 6 includes one row of red pixel rows 41, one row of green pixel rows 42 and one row of blue pixel rows 43. It can be understood that in this embodiment, it is only required to ensure that each pixel row set 6 includes one row of red pixel rows 41, one row of green pixel rows 42 and one 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, as shown in FIG. 4, 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 can 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 can be arranged in the order of red pixel row 41-green pixel row 42-blue pixel row 43. Figure 3

[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 order. It can be understood that in this embodiment, the arrangement order of the pixel rows 4 in the pixel row set 6 is limited on the premise that each pixel row set 6 includes one row of red pixel rows 41, one row of green pixel rows 42 and one row of blue pixel rows 43, but the specific arrangement manner of the pixel rows 4 of different colors is not limited.

[0069] For example, as shown in FIG. 4, the pixel rows 4 in each pixel row set 6 are arranged in the order of red pixel row 41-green pixel row 42-blue pixel row 43. Of course, as shown in FIG. 5, the pixel rows 4 in each pixel row set 6 can be arranged in the order of green pixel row 42-red pixel row 41-blue pixel row 43, or as shown in FIG. 6, the pixel rows 4 in each pixel row set 6 can be arranged in the order of red pixel row 41-blue pixel row 43-green pixel row 42. Figure 4 Figure 5

[0070] ​​​In combination with the above-described embodiment of dividing the pixel row set 6, in one pixel row set 6, the scan driving units 3 corresponding to the red pixel rows 41 can be arranged on one side of the display panel, the scan driving units 3 corresponding to the blue pixel rows 43 can be arranged on the other side of the display panel, and the scan driving units 3 corresponding to the green pixel rows 42 can be arranged on either side of the display panel; for two adjacent pixel row sets 6, if the scan driving units 3 corresponding to the green pixel rows 42 are arranged on the first side of the display panel in the first pixel row set 6, the scan driving units 3 corresponding to the green pixel rows 42 need to be arranged on the second side of the display panel in the second pixel row set 6.

[0071] Based on the above-described embodiment, in one possible implementation scenario, the scan driving units 3 corresponding to the green pixel rows 42 can be arranged on the first side (for example, the left side) of the display panel, the scan driving units 3 corresponding to the blue pixel rows 43 can be arranged on the second side (for example, the right side) of the display panel, and the scan driving units 3 corresponding to the green pixel rows 42 are alternately arranged on the two sides of the display panel. In this implementation scenario, when displaying a red pure color picture, all the scan driving units 3 corresponding to the red pixel rows 41 input the scan driving signal from left to right through the scan driving lines 1, and the scan driving signal decays from right to left after the display is completed, and for any red pixel unit R, the degree of input and decay of the scan driving signal is equivalent, so that the red pure color picture is displayed well and no horizontal lines appear; but when displaying a green pure color picture, since the scan driving units 3 corresponding to the green pixel rows 42 are alternately arranged on the two sides of the display panel, the degree of input and decay of the scan driving signal of the green pixel units G in the adjacent two green pixel rows 42 is not equivalent (the previous row inputs from left to right and decays from right to left, and the next row inputs from right to left and decays from left to right), so that horizontal lines appear when displaying the green pure color picture.

[0072] Therefore, in the case where the display panel contains red pixel units R, green pixel units G, and blue pixel units B, since the sensitivity of the human eye to blue is the lowest, the scan driving units 3 corresponding to the blue pixel rows 43 can be alternately arranged on the two sides of the display panel, the scan driving units 3 corresponding to the green pixel rows 42 can be arranged on the first side of the display panel, and the scan driving units 3 corresponding to the red pixel rows 41 can be arranged on the second side of the display panel, so as to avoid the horizontal lines being recognized by the human eye, improve the display effect of the display panel, and reduce the probability of the appearance of pure color picture horizontal lines as much as possible.

[0073] In one possible implementation example of the present application, in the mth pixel row set 6, the scan driving units 3 for driving the red pixel rows 41 are arranged on the first side of the display panel, the scan driving units 3 for driving the green pixel rows 42 are arranged on the second side of the display panel, and the scan driving units 3 for driving the blue pixel rows 43 are arranged on the first side of the display panel.

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

[0075] In one feasible embodiment of this application, in the m-th pixel row set 6, the scanning driving unit 3 for driving the red pixel row 41 is disposed on the first side of the display panel, the scanning driving unit 3 for driving the green pixel row 42 is disposed on the second side of the display panel, and the scanning driving unit 3 for driving the blue pixel row 43 is disposed on the second side of the display panel.

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

[0077] In one feasible embodiment of this application, the pixel unit 2 can be displayed via an 17T1C circuit.

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

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

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

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

[0082] Based on the display panel provided in 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 alternately placed on the left and right sides. In this display panel configuration, for one side, there is only one scanning drive unit 3 for every two rows of pixels 4, so the CLK signal of the scanning drive unit 3 is only half of the normal number. Figure 5 As shown, CLK1-CLK6 cycle through the numbers, so the left side consists of CLK1, CLK4, and CLK5, and the right side consists of CLK2, CLK3, and CLK6.

[0083] Reference Figure 6In another possible implementation of the present application, following the concept of the above implementation, in the display panel, the scan driving line 1 includes a first scan driving line 11 and a second scan driving line 12, and the nth row of pixel rows 4 is connected to the nth scan driving unit 3 through the nth first scan driving line 11 or the nth second scan driving line 12;

[0084] 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+1)th first scan driving line 11 is connected to the second end of the (n+1)th 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 at 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 at 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 one row of pixel rows 4, the first scan driving line 11 and the second scan driving line 12 are arranged below the row of pixel rows 4, and thus for n rows of pixel rows 4, there are n first scan driving lines 11 and n second scan 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+1)th first scan driving line 11 is connected to the second end of the (n+1)th 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 at 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 at the other side of the display panel. It can be understood that the first scan driving line 11 and the second scan driving line 12 described above 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+3)th scan driving unit 3 is connected to the first end of the second scan driving line 12. Based on the above arrangement, for the pixel rows 4 of the same color, the scan driving units 3 corresponding to the adjacent two rows of pixel rows 4 of the same color are respectively connected to the second end of the first scan driving line 11 and the first end of the second scan driving line 12.

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

[0090] The blue pixel row 43 and the green pixel row 42 are the same.

[0091] It can be seen that based on the above embodiment, on the one hand, the scan driving signals of all color pixel rows 4 are input in the same direction; on the other hand, compared with the embodiment of the above-mentioned embodiment of the present application, the embodiment further expands the horizontal space of the scan driving unit 3 (because in this embodiment, the scan driving unit 3 always maintains the alternating arrangement mode of left-right-left-...), which is embodied in the product, and further reduces the product frame area.

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