Description

Technical Field

[0001] This invention relates to the field of display technology, and more particularly to a display panel and a liquid crystal display. Background Technology

[0002] As the bezels of LCD displays become narrower, the wiring at the bezels also needs to be optimized. Existing technologies typically use MUX (Multiplexer) to reduce the wiring at the bezels. By using MUX, the driver can output load signals to multiple rows of sub-pixels through an output port, thereby driving multiple rows of sub-pixels.

[0003] However, because overlapping wiring is used in narrow bezel designs, a capacitor is formed when the fan-out lines of two sub-pixels overlap. If the load signal transmitted in the two overlapping fan-out lines changes abruptly, coupling pull may occur under the action of the capacitor. Consequently, the load signal in the fan-out line weakens under the influence of coupling pull, which will cause the connected sub-pixels to charge more slowly, resulting in abnormal display of the LCD screen.

[0004] Therefore, how to improve the display effect of LCD displays has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] This invention provides a display panel and a liquid crystal display (LCD) to improve the display effect of the LCD.

[0006] In a first aspect, embodiments of the present invention provide a display panel, comprising: a plurality of sub-pixels arranged in an array, and a plurality of multiplexers; in the non-display area, the polarity of the loaded signals of each column of sub-pixels is the same, the polarity of the loaded signals of adjacent columns of sub-pixels is opposite, and at least two columns of sub-pixels with the same loaded signal polarity are connected to the same multiplexer.

[0007] The plurality of multiplexers includes a first multiplexer, wherein at least two columns of the sub-pixels that are of the same color and are adjacent to each other are connected in the same first multiplexer.

[0008] Secondly, embodiments of the present invention provide a driving method for a display panel as described in the first aspect above, comprising:

[0009] The multiplexer receives the load signal;

[0010] The multiplexer drives each sub-pixel through the loading signal.

[0011] Thirdly, embodiments of the present invention provide a liquid crystal display, including: a backlight panel and a display panel as described in the first aspect above;

[0012] The display panel is used to: display based on the backlight in response to the backlight panel providing backlight to the display panel.

[0013] The beneficial effects of this invention are as follows:

[0014] This invention provides a display panel and a liquid crystal display, comprising: a plurality of sub-pixels arranged in an array, and a plurality of multiplexers; in the non-display area, the polarity of the loading signals of each column of sub-pixels is the same, and the polarity of the loading signals of adjacent columns of sub-pixels is opposite; the same multiplexer connects at least two columns of sub-pixels with the same loading signal polarity; the plurality of multiplexers includes a first multiplexer, and the same first multiplexer connects at least two columns of sub-pixels of the same color and adjacent to each other. Thus, by connecting at least two columns of sub-pixels of the same color and adjacent to each other through the first multiplexer, when the display panel displays monochrome, mixed color, or other images, the jump phenomenon on the fan-out line corresponding to the first multiplexer can be eliminated, i.e., no coupling pull occurs, thereby eliminating the influence of coupling pull on the charging of each column of sub-pixels connected to the first multiplexer, and improving the display effect of the liquid crystal display when the display panel is applied to the liquid crystal display.

[0024] The specific embodiments of a display panel and liquid crystal display provided by the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] This invention provides a display panel, such as... Figure 1 As shown, it includes: a plurality of sub-pixels 100 arranged in an array, and a plurality of multiplexers 200; in the non-display area, the sub-pixels 100 in each column have the same polarity of the loaded signal, and the sub-pixels 100 in adjacent columns have opposite polarities of the loaded signal; the same multiplexer 200 connects at least two columns of sub-pixels 100 with the same loaded signal polarity; the plurality of multiplexers 200 includes a first multiplexer, and the same first multiplexer connects at least two columns of sub-pixels 200 that are of the same color and adjacent to each other. Figure 1 The loading signal polarity of the sub-pixels 100 filled with black dots is the same, and the loading signal polarity of the sub-pixels 100 not filled with black dots is the same. The letters in each sub-pixel 100 represent the color of the sub-pixel: "R" is the red sub-pixel, "G" is the green sub-pixel, and "B" is the blue sub-pixel.

[0026] In this way, by connecting at least two columns of sub-pixels with the same color and adjacent to each other through the first multiplexer, when displaying monochrome, mixed color, or other images on the display panel, the jump phenomenon on the fan-out line corresponding to the first multiplexer can be eliminated, that is, no coupling pull will occur. This eliminates the impact of coupling pull on the charging of each column of sub-pixels connected to the first multiplexer, thus improving the display effect of the LCD when the display panel is applied to the LCD.

[0027] It should be understood that there are certain critical display screens for LCD monitors. These critical screens are the most prone to problems during display, and therefore, they are usually monitored and improved. Common critical display screens include, but are not limited to: monochrome screens, mixed color screens, and Excel-style screens. For example, when displaying a monochrome screen with green sub-pixels, the brightness and grayscale of each green sub-pixel in the LCD monitor are the same, while the red and blue sub-pixels are not driven. Similarly, when displaying a mixed color screen with blue and green sub-pixels, the brightness and grayscale of each green and blue sub-pixel are the same, while the red sub-pixels are not driven. Furthermore, when displaying an Excel-style screen, a portion of the LCD monitor displays white, while the remaining portion displays black.

[0028] Optionally, such as Figure 1 As shown, each multiplexer 200 is a first multiplexer. Thus, when the display panel displays monochrome or mixed-color images, the jump phenomenon on the fan-out lines corresponding to each multiplexer 200 can be eliminated, i.e., no coupling pull occurs. This eliminates the impact of coupling pull on the charging of each column of sub-pixels 100, thereby eliminating vertical stripe defects on the display panel under monochrome and mixed-color images. When the display panel is applied to a liquid crystal display (LCD), it can improve the overall display effect of the LCD.

[0029] Furthermore, such as Figure 1 As shown, each column of sub-pixels 100 connected to each first multiplexer is spaced apart by the same number of columns of sub-pixels 100. Thus, since each pixel on the display panel includes sub-pixels 100 of three colors—red (R), green (G), and blue (B)—and the polarities of adjacent columns of sub-pixels 100 are different, when the pixels are arranged in an array, each column of sub-pixels connected to the first multiplexer is spaced apart by five columns of sub-pixels 100. This ensures that the arrangement of sub-pixels 100 in each pixel is identical, resulting in a more uniform display on the display panel and simplifying the wiring structure between the multiplexer 200 and each sub-pixel 100.

[0030] Optionally, such as Figure 2 As shown, each multiplexer includes multiple transistors 201. In the same multiplexer, the input terminals of the multiple transistors 201 are connected to the same load signal input terminal S via fan-out lines L. Figure 2 The transistor 201 has six input terminals (S1 to S6) connected to each other, and the output terminals of multiple transistors 201 are connected to different columns of sub-pixels 100 respectively. The control terminals of multiple transistors 201 are connected to different control signal lines. The control terminals of transistors 201 connected to the two columns of sub-pixels 100 in each group are connected to control signal lines that load different control signals.

[0031] In order to simplify the circuit structure, Figure 2 Only one subpixel 100 is shown in each column, which does not mean that there is only one subpixel 100 in each column. The number of subpixels 100 in each column in the actual display panel can be set according to actual needs, and is not limited here.

[0032] In this way, by changing the connection method between the transistor control terminal and the control signal line, when the Excel screen is displayed on the display panel, the switching direction of the fan-out line corresponding to the multiplexer can be made consistent, so that no coupling pull will occur. This eliminates the gray line that appears at the black and white boundary caused by coupling pull when displaying the Excel screen, thus eliminating the Excel dotted line defect on the display panel. When the display panel is applied to an LCD monitor, the display effect of the LCD monitor is improved.

[0033] Furthermore, since sub-pixel 100 can be considered equivalent to a capacitor, therefore Figure 2 In the representation of subpixel 100, capacitance is used. The "+" and "-" on both sides of subpixel 100 are used to indicate the polarity of subpixel 100, for example, as shown in the image. Figure 2 As shown, sub-pixels R1 and G1 have different polarities, sub-pixels R1 and R2 have different polarities, sub-pixels R1 and B1 have the same polarity, and sub-pixels G1 and R2 have the same polarity. The end of each sub-pixel 100 furthest from transistor 201 is connected to the same potential V1.

[0034] It should be understood that Figure 2 The circuit includes control signal input terminals M1 and M2. The two control signal input terminals (M1 and M2) alternately output control signals. In order to reduce the load on each control signal line, each control signal input terminal is connected to two control signal lines. Of course, each control signal input terminal can also be connected to one control signal line to simplify the circuit, or each control signal input terminal can be connected to three, four or more control signal lines to further reduce the load on each control signal line. The number of control signal lines connected to each control signal input terminal can be set according to actual needs and is not limited here.

[0035] It is worth noting that a jump in the fan-out line can be understood as a change in the applied signal voltage on the fan-out line, while the absence of a jump can be understood as no change in the applied signal voltage on the fan-out line. When a jump occurs, the direction of the jump includes upward and downward jumps. An upward jump can be understood as an increase in the applied signal voltage, and a downward jump can be understood as a decrease in the applied signal voltage. For example, as... Figure 2 As shown, Figure 2The CCP includes six fan-out lines L: L1, L2, L3, L4, L5, and L6. If, in a certain frame, only sub-pixels R1, G1, B1, and R3 are driven, with the same absolute value of the driving voltage, and control signals M1 and M2 sequentially control the transistor 300 connected to them to turn on, then the loading signals transmitted in fan-out line L1 are sequentially: the loading signal driving sub-pixel R1, then the loading signal driving sub-pixel R3, meaning there is no jump in the loading signals transmitted in fan-out line L1; the loading signals transmitted in fan-out line L2 are sequentially: driving sub-pixel R1, then the loading signal driving sub-pixel R3. The loading signal for sub-pixel G1 and the loading signal driving sub-pixel G3, based on the polarity of the sub-pixels, show the former being a negative voltage and the latter zero. Therefore, the loading signal jumps from negative voltage to zero, meaning there is a jump in the loading signal transmitted in fan-out line L2, and the jump direction is upward. The loading signals transmitted in fan-out line L3 are, sequentially, the loading signal driving sub-pixel B1 and the loading signal driving sub-pixel B3. The former is a positive voltage and the latter zero, so the loading signal jumps from positive voltage to zero, meaning there is a jump in the loading signal transmitted in fan-out line L3, and the jump direction is downward. Furthermore, when the jump directions of the two fan-out lines are different, or one has a jump and the other does not, a coupling pull phenomenon will occur between these two fan-out lines.

[0036] Furthermore, such as Figure 2 As shown, two adjacent loading signal input terminals S are grouped together. Within each group, the fan-out lines L connected to the two loading signal input terminals S are respectively located in different film layers, and the fan-out lines L overlap. Specifically, loading signal input terminals S1 and S2, S3 and S4, and S5 and S6 can be considered as a group, thus the fan-out lines L1 and L2 overlap, L3 and L4 overlap, and L5 and L6 overlap.

[0037] Thus, when two fan-out lines overlap, if they are coupled and pulled, it will have a significant impact on the charging of sub-pixels. Therefore, by eliminating the coupling and pulling between the overlapping fan-out lines, the impact of coupling and pulling on the charging of each column of sub-pixels can be eliminated, which can effectively improve the display effect of the LCD when the display panel is applied to the LCD.

[0038] In addition, since the coupling pull between two non-overlapping fan-out lines is small and can be ignored, the focus when improving the display effect of an LCD monitor is on the coupling pull between overlapping fan-out lines.

[0039] It should be understood that, such as Figure 3 As shown, Figure 3 This is a schematic diagram of the cross-section at point L of the fan-out line of the LCD monitor. Figure 3As can be seen, the fan-out lines L are set in pairs. For example, the dashed box Q1 contains a pair of fan-out lines L. Each pair of fan-out lines L is set overlapping. Obviously, the overlapping pair of fan-out lines L forms a capacitor structure, which is more susceptible to the influence of coupling pull. Therefore, eliminating coupling pull can improve the display effect of the LCD.

[0040] The following is based on Figure 2 Taking the circuit structure shown as an example, fan-out lines L1 and L2 overlap, fan-out lines L3 and L4 overlap, and fan-out lines L5 and L6 overlap. The Excel screen is divided between sub-pixels B2 and R3, with a white screen on the left and a black screen on the right. This explains the principle of eliminating the poor quality of dotted lines on the Excel display panel.

[0041] First, in the part displaying the white image, the loading signals of sub-pixels R1, B1, and G2 are positive voltages, and the loading signals of sub-pixels G1, R2, and B2 are negative voltages. In the part displaying the black image, none of the sub-pixels are driven, so the loading signals of sub-pixels R3, G3, B3, R4, G4, and B4 are all zero.

[0042] Next, when control signals are input to control signal input terminals M1 and M2 respectively, the load signal on fan-out line L1 jumps from positive voltage to zero, i.e., downward; the load signal on fan-out line L2 jumps from zero to negative voltage, i.e., downward; the load signal on fan-out line L3 jumps from zero to positive voltage, i.e. upward; the load signal on fan-out line L4 jumps from negative voltage to zero, i.e. upward; the load signal on fan-out line L5 jumps from positive voltage to zero, i.e., downward; and the load signal on fan-out line L6 jumps from zero to negative voltage, i.e., downward.

[0043] Therefore, fan-out lines L1 and L2 both jump downwards in the same direction, with no coupling pull; fan-out lines L3 and L4 both jump upwards in the same direction, with no coupling pull; fan-out lines L5 and L6 both jump downwards in the same direction, with no coupling pull. Thus, there is no coupling pull between the overlapping fan-out lines, preventing gray lines from appearing at the black-and-white boundary, eliminating the poor dashed line quality in Excel images, and improving the display effect of the LCD monitor.

[0044] Of course, such as Figure 4 As shown, adjacent columns of sub-pixels 100 are grouped together, and the control terminals of transistors 201 connected to the two columns of sub-pixels 100 within each group can also be connected to control signal lines that load the same control signal. This connection method can eliminate vertical stripe defects in monochrome and mixed-color images, improving the display effect of liquid crystal displays when the display panel is used.

[0045] The following is based on Figure 4 Taking the circuit structure shown as an example, fan-out lines L1 and L2 are arranged in an overlapping manner, fan-out lines L3 and L4 are arranged in an overlapping manner, and fan-out lines L5 and L6 are arranged in an overlapping manner. When displaying a green monochrome image, the principle of eliminating the vertical stripe defect problem of the display panel is explained.

[0046] First, the loading signals for sub-pixels G1 and G3 are negative voltages, the loading signals for sub-pixels G2 and G4 are positive voltages, and the loading signals for the remaining sub-pixels: sub-pixels R1, B1, R2, B2, R3, B3, R4, and B4 are all zero.

[0047] Next, when control signals are input to control signal input terminals M1 and M2, the load signals on fan-out lines L1, L2, L3, L4, L5, and L6 do not change, that is, there is no jump and no coupling pull.

[0048] Therefore, there is no coupling or pulling between the overlapping fan-out lines, so the display panel will not produce abnormal vertical lines, eliminating the vertical line defects under monochrome images and improving the display effect of the LCD.

[0049] Furthermore, the principle of eliminating vertical stripe defects in mixed-color images is similar to that of eliminating vertical stripe defects in monochrome images, and will not be elaborated here.

[0050] In addition to the methods mentioned above, the following methods can also be used to improve the display effect of LCD monitors.

[0051] Method 1: Multiple multiplexers also include a second multiplexer, where the same second multiplexer connects at least two adjacent columns of sub-pixels of different colors. For example... Figure 5 As shown, the multiplexers connected to sub-pixels G1, B1, G3, and B3 are all second multiplexers.

[0052] Thus, by setting a second multiplexer, when the resistance of the fan-out lines is inconsistent, at least some overlapping fan-out lines can be coupled and pulled, thereby reducing the charging speed of the sub-pixel corresponding to the fan-out line with lower resistance, thereby improving the uniformity of the display panel and improving the display effect of the liquid crystal display.

[0053] Furthermore, such as Figure 5As shown, the first multiplexer connects two adjacent columns of red sub-pixels; one type of second multiplexer connects adjacent columns of blue and green sub-pixels, such as the second multiplexer connecting sub-pixels B1 and G2, or the second multiplexer connecting sub-pixels B3 and G4; another type of second multiplexer connects adjacent columns of green and red sub-pixels, such as the second multiplexer connecting sub-pixels G1 and R2, or the second multiplexer connecting sub-pixels G3 and R4.

[0054] The following is based on Figure 5 Taking the circuit structure shown as an example, fan-out lines L1 and L2 are arranged in an overlapping manner, fan-out lines L3 and L4 are arranged in an overlapping manner, and fan-out lines L5 and L6 are arranged in an overlapping manner. The resistance of fan-out lines L2, L4 and L6 is relatively small, and when displaying a green monochrome image, the principle of improving the display uniformity of the display panel is explained.

[0055] First, the loading signals for sub-pixels G1 and G3 are negative voltages, the loading signals for sub-pixels G2 and G4 are positive voltages, and the loading signals for the remaining sub-pixels: sub-pixels R1, B1, R2, B2, R3, B3, R4, and B4 are all zero.

[0056] Next, when control signals are input to control signal input terminals M1 and M2 respectively, the load signals on fan-out line L1 and fan-out line L4 do not change, that is, no jump occurs; the load signal on fan-out line L2 jumps from negative voltage to zero, that is, an upward jump; the load signal on fan-out line L3 jumps from zero to positive voltage, that is, an upward jump; the load signal on fan-out line L5 jumps from negative voltage to zero, that is, an upward jump; the load signal on fan-out line L6 jumps from zero to positive voltage, that is, an upward jump.

[0057] Therefore, there is a coupling pull between fan-out line L1 and fan-out line L2, which reduces the charging speed of sub-pixel G1 connected to fan-out line L2, suppresses excessive charging caused by the low resistance of fan-out line L2, and improves the display uniformity of the display panel; there is a coupling pull between fan-out line L3 and fan-out line L4, which reduces the charging speed of sub-pixel G2 connected to fan-out line L3, suppresses excessive charging caused by the low resistance of fan-out line L3, and improves the display uniformity of the display panel; there is no coupling pull between fan-out line L5 and fan-out line L6.

[0058] In this way, when displaying a green monochrome image, some fan-out lines can be coupled and pulled together. This coupling and pulling can balance the charging rate between sub-pixels when the resistance of the fan-out lines is inconsistent, thereby improving the uniformity of the display panel and enhancing the display effect of the LCD.

[0059] Method 2: Multiple multiplexers also include a third multiplexer, where the same third multiplexer connects at least two columns of sub-pixels of different colors and spaced apart. For example... Figure 6 As shown, the multiplexers connected to sub-pixel R1 and sub-pixel R3 are both third multiplexers.

[0060] In this way, when displaying a monochrome image on the display panel, the coupling pull between overlapping fan-out lines is eliminated, thereby eliminating the impact of coupling pull on the charging of each column of sub-pixels, preventing the occurrence of vertical stripe defects, and improving the display effect of the LCD when the display panel is applied to the LCD.

[0061] Furthermore, such as Figure 6 As shown, the first multiplexer connects two adjacent columns of blue sub-pixels, such as the first multiplexer connecting sub-pixels B1 and B3, and the first multiplexer connecting sub-pixels B2 and B4; the second multiplexer connects adjacent columns of red and green sub-pixels, such as the second multiplexer connecting sub-pixels G1 and R2, and the second multiplexer connecting sub-pixels G3 and R4; the third multiplexer connects adjacent columns of green and red sub-pixels, such as the third multiplexer connecting sub-pixels R1 and G2, and the third multiplexer connecting sub-pixels R3 and G4.

[0062] The following is based on Figure 6 Taking the circuit structure shown as an example, fan-out lines L1 and L2 are arranged in an overlapping manner, fan-out lines L3 and L4 are arranged in an overlapping manner, and fan-out lines L5 and L6 are arranged in an overlapping manner. When displaying a green monochrome image, the principle of eliminating the vertical stripe defect problem of the display panel is explained.

[0063] First, the loading signals for sub-pixels G1 and G3 are negative voltages, the loading signals for sub-pixels G2 and G4 are positive voltages, and the loading signals for the remaining sub-pixels: sub-pixels R1, B1, R2, B2, R3, B3, R4, and B4 are all zero.

[0064] Next, when control signals are input to control signal input terminals M1 and M2 respectively, the load signals on fan-out line L3 and fan-out line L4 do not change, that is, no jump occurs; the load signal on fan-out line L1 jumps from zero to positive voltage, that is, jumps upward; the load signal on fan-out line L2 jumps from negative voltage to zero, that is, jumps upward; the load signal on fan-out line L5 jumps from zero to positive voltage, that is, jumps upward; the load signal on fan-out line L6 jumps from negative voltage to zero, that is, jumps upward.

[0065] Therefore, the jump directions of fan-out line L1 and fan-out line L2 are the same, with no coupling pull; neither fan-out line L3 nor fan-out line L4 jumps, with no coupling pull; and the jump directions of fan-out line L5 and fan-out line L6 are the same, with no coupling pull.

[0066] Thus, by setting up a first multiplexer, a second multiplexer, and a third multiplexer, the coupling pull phenomenon between overlapping fan-out lines is eliminated when displaying a green monochrome image, thereby preventing the occurrence of vertical stripe defects when displaying a green monochrome image, and improving the display effect of the LCD when the display panel is applied to an LCD monitor.

[0067] Optionally, the multiplexer is connected to two sub-pixels; or, the multiplexer is connected to three sub-pixels. The connection method between the multiplexer and three sub-pixels can be as follows: Figure 7 As shown, three control signal input terminals M1, M2, and M3 need to be set at this time. Additionally, although... Figure 7 To adopt Figure 4 The circuit diagram showing the connection method of the multiplexer and the three sub-pixels is shown, but the circuit diagram described above is different. Figure 2 , Figure 5 and Figure 6 As shown in the connection method, the multiplexer can also be connected to three sub-pixels.

[0068] Thus, when a multiplexer is connected to two or three multiplexers, the display effect of the LCD can be improved through the methods described above, thus broadening the application range of the display panel.

[0069] Of course, when the multiplexer is connected to four, five or more sub-pixels, the display effect of the LCD can also be improved by the methods described above. The number of sub-pixels connected to the multiplexer is not limited here.

[0070] It should be understood that the green monochrome image has been used repeatedly as an example in the above explanation because the human eye is more sensitive to green monochrome images. Therefore, improving the display effect of the LCD monitor on green monochrome images can better enhance the user's viewing experience. Of course, if it is necessary to improve red or blue monochrome images, the display panels with the connection methods described above can also be used. Simply replace the green sub-pixels in the display panels described above with the sub-pixels whose colors need to be improved. The specific settings will not be elaborated here.

[0071] Based on the same inventive concept, embodiments of the present invention also provide a driving method for a display panel as described above, such as... Figure 8 As shown, it includes:

[0072] S801, the multiplexer receives the load signal;

[0073] The S802 multiplexer drives each sub-pixel through a loading signal.

[0074] Thus, by using the display panel described above, when the first multiplexer connects at least two columns of sub-pixels with the same color and adjacent to each other, and when the display panel displays monochrome, mixed color, or other images, the jump phenomenon on the corresponding fan-out line of the first multiplexer can be eliminated, that is, no coupling pull will occur, thereby eliminating the influence of coupling pull on the charging of each column of sub-pixels connected to the first multiplexer, and improving the display effect of the liquid crystal display when the display panel is applied to the liquid crystal display.

[0075] Based on the same inventive concept, this invention also provides a liquid crystal display. The implementation principle of the liquid crystal display is similar to that of the aforementioned display panel. The specific implementation method of the liquid crystal display can be found in the aforementioned display panel embodiments, and repeated details will not be described again.

[0076] Specifically, an embodiment of the present invention provides a liquid crystal display, such as... Figure 9 As shown, it includes: a backlight panel 901 and a display panel 902 as described above; the display panel 902 is used to: display based on the backlight in response to the backlight panel 901 providing backlight to the display panel 902.

[0077] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
