[0069] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the technical solutions of the present disclosure, but not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments described in this disclosure without making any creative efforts shall fall within the scope of protection of the technical solutions of the present disclosure.
[0070] The terms "first," "second," and the like in the description and claims of the present invention and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, such that the embodiments of the present invention described herein can be practiced using orders other than those illustrated or described herein.
[0071] The preferred embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
[0072] An array substrate proposed in an embodiment of the present disclosure, as shown in Figure 1, includes: a display area and a non-display area, the display area includes multiple rows of gate lines and multiple columns of data lines, the multiple rows of gate lines and the multiple columns of data lines intersect to define multiple sub-pixel rows, the sub-pixel rows include pixel electrodes and transistors, and the side of the pixel electrode extending along the gate line is larger than the side of the data line extending.
[0073] First of all, it should be explained that the peripheral circuit of the array substrate usually includes a system on chip (SOC), a timing controller, and a data driver chip. Of course, in actual applications, the implementation of the SOC can be determined according to the needs of the actual application and is not limited here. The above-mentioned timing controller can store an overdrive relationship table, etc., and perform display control during the display process of the display panel. The number of the above-mentioned data driver chips is usually multiple, and each data driver chip is used to provide data voltages to the sub-pixels in the display area to achieve color display of the picture.
[0074] In the embodiment of the present application, the array substrate includes a display area and a non-display area. The display area primarily displays images through multiple sub-pixel rows. The display area includes multiple rows of gate lines and multiple columns of data lines. The multiple rows of gate lines and multiple columns of data lines intersect to define multiple sub-pixel rows, and each sub-pixel is controlled by the gate lines and data lines. The sub-pixel rows include pixel electrodes and transistors. During the display process, the gate lines control the conduction of the transistors through gate signals, and the data lines provide data signals to the pixel electrodes through the conductive transistors.
[0075] It should be noted that the array substrate in the embodiment of the present application has a triple-gate pixel architecture, and the side of the pixel electrode extending along the gate line is greater than the side extending along the data line, that is, the horizontal side length of the array substrate in the embodiment of the present application is greater than the vertical side length. It should be noted that when the pixel electrode is a plate-shaped electrode, the side of the pixel electrode extending along the gate line is greater than the side extending along the data line. When the pixel electrode has a structure with a slit and branch electrodes, the edge connection line of the pixel electrode composed of multiple branch electrodes serves as the side of the pixel electrode extending along the gate line.
[0076] The non-display area includes a plurality of cascaded shift registers GOA.
[0077] In an embodiment of the present application, optionally, multiple shift registers are evenly distributed on both sides of the display area, and the gate signals in the above-mentioned gate lines are provided by corresponding GOAs, or the shift registers are set on one side of the non-display area, which is not limited here.
[0078] The display area is described in detail below. The display area includes multiple row groups repeatedly arranged along the column direction. Each row group includes: M sub-pixel rows with different colors arranged along the column direction. The sub-pixels in the same sub-pixel row have the same color.
[0079] In the embodiment of the present application, the sub-pixels included in the display area are first divided into row groups. That is, in units of columns, a row of M sub-pixels with different red, green, and blue colors arranged along the column direction is called a group. The value of M is usually at least three. In the rows of sub-pixels including red, green, blue, and white, the minimum value of M is usually four. In the above row group, the sub-pixels in the same sub-pixel row have the same color, that is, at least three or four sub-pixel rows with different colors in a column constitute a row group.
[0080] Two sub-pixel rows of the same color in the two adjacent row groups constitute a row unit.
[0081] Considering that sub-pixels of different colors are arranged sequentially in a row group, in the embodiment of the present application, two sub-pixels of the same color are found in two adjacent row groups, and the above two sub-pixels are called a row unit.
[0082] Since the shift registers correspond to the sub-pixel rows one by one, the multiple cascaded shift registers include multiple register groups, each register group includes two shift registers, and the two shift registers are adjacently arranged or there are M-1 shift registers between the two shift registers.
[0083] One register group corresponds to one row unit.
[0084] The first shift register in the register group is connected to the first sub-pixel row in the corresponding row unit, and the second shift register is connected to the second sub-pixel row in the corresponding row unit.
[0085] In an embodiment of the present application, after two adjacent row groups are divided into a row unit, each shift register is also divided, that is, two shift registers are divided into a register group. In this way, one register group corresponds to one row unit, and each shift register in the register group corresponds to one sub-pixel row.
[0086] In order to achieve simultaneous charging of sub-pixels of the same color connected to the same data line, two schemes are provided in the embodiments of the present application: Scheme 1, two shift registers are arranged adjacent to each other, that is, the two adjacent shift registers are divided into a register group; there are M-1 shift registers between the two shift registers, that is, the two shift registers corresponding to two sub-pixel rows of the same color are divided into a register group.
[0087] In order to display the image normally, the array substrate further includes a plurality of clock signal lines. Each shift register is connected to one clock signal line, that is, the shift register is started under the driving control of the clock signal line.
[0088] When the array substrate operates in the first mode, the clock signals on the clock signal lines connected to the same register group are the same, and the clock signals on the clock signal lines connected to two adjacent register groups have a first phase difference.
[0089] It should be noted that the first mode described above is the DLG mode. In this first mode, the clock signals on the clock signal lines connected to the two shift registers within the same register group are identical. This ensures that the gate lines of the two shift registers within the same register group can simultaneously provide drive signals to the two sub-pixel rows of the same color included in the corresponding row unit. To ensure normal operation of the entire array substrate, the clock signals on the clock signal lines connected to the two adjacent register groups have a first phase difference. In this way, the two adjacent registers can time-share the drive signals to the two adjacent sub-pixel rows of different colors, thereby ensuring row-by-row driving of each sub-pixel row.
[0090] In addition, there are two ways to arrange the sub-pixels and the connected data lines in the embodiments of the present application. The first way is shown in Figure 2. The sub-pixels located in different rows connected to the same data line are arranged on both sides of the same data line. Optionally, referring to Figure 2, the three sub-pixels from top to bottom surrounded by dotted lines can be the sub-pixels corresponding to red, green and blue respectively, and the sub-pixels in the same row have the same color.
[0091] In the embodiment of the present application, sub-pixels located in different rows and the data lines connected thereto are arranged in a zigzag pattern, that is, sub-pixels located in different rows connected to the same data line are arranged on both sides of the same data line.
[0092] The second method is shown in FIG. 3 , where sub-pixels in different rows connected to the same data line are arranged on the same side of the same data line.
[0093] In the embodiment of the present application, sub-pixels in different rows are arranged in line with the data lines they are connected to. That is, sub-pixels in different rows connected to the same data line are arranged on the same side of the same data line. Compared to the method shown in Figure 2, this second method provides a more uniform color display and a better display effect because the sub-pixels driven simultaneously are on the same side of the same data line.
[0094] After introducing the basic structure of the array substrate in the embodiment of the present application, the following describes in detail the two schemes provided in the embodiment of the present application. As shown in Figure 4, in Scheme 1, the two shift registers are arranged adjacent to each other. Referring to Figure 10, there are M-1 shift registers between the two shift registers in Scheme 2. Both Scheme 1 and Scheme 2 can achieve the simultaneous opening and charging of two sub-pixels of the same color corresponding to the same register group, that is, at the same moment, the gate line controls the simultaneous opening of two sub-pixel rows of the same color and the data line charges the same data signal into the above two sub-pixels.
[0095] Referring to FIG4 , the specific approach of Solution 1 is to change the connection relationship between the output of the shift register in the non-display area and each sub-pixel in the display area. For example, FIG4 shows six sub-pixels arranged along the column direction, including red, green, and blue. The first sub-pixel and the fourth sub-pixel have the same color, the second sub-pixel and the fifth sub-pixel have the same color, and the third sub-pixel and the sixth sub-pixel have the same color. The first sub-pixel and the fourth sub-pixel form a row unit, the second sub-pixel and the fifth sub-pixel form a row unit, and the third sub-pixel and the sixth sub-pixel form a row unit.
[0096] Accordingly, to correspond to the row units, the shift register connected to the first sub-pixel and the shift register connected to the fourth sub-pixel in the non-display area form a register group, the shift register connected to the second sub-pixel and the shift register connected to the fifth sub-pixel form a register group, and the shift register connected to the third sub-pixel and the shift register connected to the sixth sub-pixel form a register group. Each register group is connected to the sub-pixel row in the corresponding row unit via the connection shown in FIG4 .
[0097] Referring to FIG. 5 , it should be noted that, in the first mode of Scheme 1, the width of the data signal loaded into the same row of cells is 2H, where H is the charging time of a row of sub-pixels. Referring to FIG. 5 , Gout1 and Gout4 are simultaneously turned on as a group, followed by Gout2 and Gout5, Gout3 and Gout6, and so on, and so on. The details are not further described.
[0098] During implementation, the width of the time for writing the data signal into the sub-pixel row is 2H. That is, the driving method at this time can increase the charging time of the pixel row, which is suitable for high-resolution products.
[0099] Referring to FIG6 , it should be noted that, in the second mode of the first solution, which is generally a non-DLG mode, the width of the data signal loaded into a row of sub-pixels is 1H. Referring to FIG6 , the order in which the gate lines are turned on is Gout1, Gout4, Gout2, Gout5, Gout3, and Gout6, and the phase difference in the timing of the opening of adjacent gate lines is 1H, that is, Gout4 is turned on 1H later than Gout1, Gout2 is turned on 1H later than Gout4, and so on.
[0100] Specifically, referring to FIG. 7 , the operation mode of the array substrate further includes a second mode.
[0101] When the array substrate operates in the second mode, clock signals on clock signal lines connected to the same register group have a second phase difference, and clock signals on clock signal lines connected to two adjacent register groups have a second phase difference.
[0102] During implementation, when the array substrate operates in non-DLG mode, the clock signals on the clock signal lines connected to the two shift registers within the same register group have a second phase difference. This ensures that the gate lines of the two shift registers within the same register group can provide drive signals to the two sub-pixel rows of the same color included in the corresponding row unit at equal time intervals. To achieve a more uniform display across the entire array substrate, the clock signals on the clock signal lines connected to two adjacent register groups also have a second phase difference. This allows the two adjacent registers to provide drive signals to the two adjacent sub-pixel rows of different colors at equal time intervals, thereby ensuring row-by-row driving of each sub-pixel row.
[0103] Since the refresh rate is doubled in the DLG mode, the first phase difference is twice the second phase difference.
[0104] Still using the two register groups including six sub-pixel rows of red, green and blue for explanation, it can be seen from Figure 7 that in Scheme 1, the cascade relationship between the shift registers is: the cascade output signal Out_C of the first shift register is connected to the input terminal Input of the seventh shift register, and the cascade output signal Out_C of the second shift register is connected to the input terminal Input of the eighth shift register. Optionally, this case is provided with a cascade output terminal Out_C and a gate signal output terminal Gout, wherein the cascade output terminal Out_C is used to transmit the cascade carry and reset signals, and the gate signal output terminal Gout is used to achieve electrical connection with the gate line of the display area and transmit the gate start signal. Of course, this case can also be provided with only a gate signal output terminal Gout, that is, the gate signal output terminal Gout is used to transmit the cascade carry and reset signals and transmit the display area gate line start signal. Referring to Figure 7 , in this embodiment, the cascade output of the Nth stage GOA (GOA N) is used to provide a signal to the input of GOA N+6, and the cascade output of GOA N+8 is used to provide a reset signal to GOA N, and so on for subsequent registers. At the same time, the output signal of the shift register after the sixth shift register is connected to the reset terminal of the first shift register, the output signal of the shift register after the seventh shift register is connected to the reset terminal of the second shift register, and so on.
[0105] Specifically, the clock signals corresponding to each sub-pixel row in the first mode in the embodiment of the present application are shown in Figure 8, that is, in the DLG mode, the clock signals corresponding to the sub-pixels in the next row of adjacent rows are 2H later than the clock signals corresponding to the sub-pixels in the previous row. Referring to Figure 8, during the implementation process, there is no need to make special adjustments to the clock signal in the DLG mode. It is only necessary to make adjustments to the correspondence between the output end of the GOA and the gate line (that is, CLK1 and CLK2 can be turned on at the same time, and the second GOA corresponding to CLK2 is electrically connected to the 4th gate line of the display panel) to realize the DLG function of the triple Gate, which ensures cost reduction and improves the charging rate of the display panel.
[0106] Specifically, the clock signals corresponding to each sub-pixel row in the second mode in the embodiment of the present application are shown in Figure 9, that is, in the DLG mode, the clock signal corresponding to the sub-pixels in the next row of adjacent rows is 1H later than the clock signal corresponding to the sub-pixels in the previous row.
[0107] After introducing Solution 1, Solution 2 in the embodiment of this application will be introduced in detail.
[0108] Referring to FIG. 10 , unlike Solution 1, the connection relationship between the output of the shift register in the non-display area and the sub-pixels in the display area remains unchanged. For example, FIG. 1 illustrates six sub-pixels, including red, green, and blue, arranged along the column direction. The first sub-pixel and the fourth sub-pixel have the same color, the second sub-pixel and the fifth sub-pixel have the same color, and the third sub-pixel and the sixth sub-pixel have the same color. The first sub-pixel and the fourth sub-pixel form a row unit, the second sub-pixel and the fifth sub-pixel form a row unit, and the third sub-pixel and the sixth sub-pixel form a row unit.
[0109] In the non-display area, the shift register connected to the first subpixel and the shift register connected to the fourth subpixel form a register group, the shift register connected to the second subpixel and the shift register connected to the fifth subpixel form a register group, and the shift register connected to the third subpixel and the shift register connected to the sixth subpixel form a register group. Each register group is connected to a subpixel row in the corresponding row unit via the connection shown in Figure 10, that is, the shift registers are connected to the subpixel rows in a one-to-one correspondence.
[0110] In the embodiment of the present application, the connection relationship between the shift register and the clock signal line is as follows:
[0111] The 12k-11th stage shift register is connected to the first clock signal line of the plurality of clock signal lines;
[0112] The 12k-10th stage shift register is connected to the second clock signal line among the multiple clock signal lines;
