[0031] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art.

[0032] In addition, described feature, structure or characteristic can be combined in one or more embodiments in any suitable manner.In the following description, many specific details are provided so as to provide a full understanding of the embodiments of the present application. However, it will be appreciated by those skilled in the art that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps etc. can be adopted. In other cases, known methods, devices, implementations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0033] The present application is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limiting the present application.

[0034] The display industry is pursuing ever-higher refresh rates. A recent technology, called HSR (Hardware Super Resulation), has emerged, which uses low refresh rates to drive high refresh rates. For example, a 4K×2K UHD (Ultra High Definition) 60Hz display can be displayed as a 4K×1K UHD 120Hz display by adjusting the timing. Similarly, a 4K×2K UHD 120Hz display can be displayed as a 4K×1K UHD 240Hz display by adjusting the timing. Because the total amount of data displayed is the same, the driver component specifications remain the same. Simply adjusting the timing doubles the refresh rate, but of course the resolution is halved. End users can freely switch between these two display states using a remote control.

[0035] The driver receives display data one sub-pixel at a time, and sequentially. Then, each sub-pixel in a row is processed using its own internal data channel and converted into grayscale voltage to reach its respective output port. For example, UHD Figure 1 As shown: merging the first and second columns of red, the TCON sends the first column of red data, then copies the first column of red data and sends it again, which will give the second column of red. However, the purpose is to increase the refresh rate (the refresh rate is doubled after the horizontal pixel merging), and the amount of data that the TCON needs to send for a horizontal row after the copy is still the same as UHD. However, the refresh rate is doubled, and the time for a row is halved. The TCON cannot send so much data, which is not feasible. If the TCON sends the first column of red data and then directly sends the third column of red data, all driver chips will receive the data sequentially. The third column of red data will be given to the second column of red, and the display will also be incorrect. Therefore, the existing driver chips do not support merging two columns of pixels into one.

[0036] Furthermore, a display panel in the current industry can only achieve compatibility between 4K×2K×60Hz and 4K×1K×120Hz, and cannot achieve compatibility between 4K×2K×60Hz, 4K×1K×120Hz, 2K×2K×120Hz, and 2K×1K×240Hz. It is also impossible to increase the refresh rate while involving 4K changes in 4K×2K×60Hz.

[0037] In order to solve the above problems, the present application provides a display panel, which specifically includes the following embodiments:

[0038] Figure 2 FIG. 1 is a schematic diagram of the structure of a display panel provided in an embodiment of the present application; FIG. Figure 2As shown, the display panel 100 includes: 2N rows of scan lines 110, M columns of data lines 120, and pixel circuits 130 arranged in an array; wherein the number of columns of the pixel circuits 130 is M, and the number of rows is N; that is, the number of columns of the pixel circuits 130 in the display panel 100 is the same as the number of data lines 120, and the number of rows of the pixel circuits 130 is half of the scan lines 110. Figure 2 The scan lines 110 and data lines 120 in FIG. 1 cross but are not connected. Figure 2 In the figure, G1, G2, G3, G4, G5 and G6 respectively represent the first row of scan line 110, the second row of scan line 110, the third row of scan line 110, the fourth row of scan line 110, the fifth row of scan line 110 and the sixth row of scan line 110, and S1, S2, ..., S6 respectively represent the first column of data line 120, the second column of data line 120, ..., the sixth column of data line 120.

[0039] In one embodiment, each pixel circuit 130 includes a pixel unit 132 and a control unit 131. The control unit 131 is used to input the data signal on the data line 120 into the pixel unit 132 when it is in a conductive state, thereby charging the pixel unit 132 through the data signal on the data line 120; on the contrary, when the control unit 131 is in an off state (i.e., a non-conductive state), the data signal on the data line 120 cannot be input into the pixel unit 132, thereby not charging the pixel unit 132; it should be noted that the display panel 100 can be a liquid crystal display (LCD) or an OLED (Organic Light-Emitting Diode) display; when the display panel 100 is a liquid crystal display, the pixel unit 132 includes liquid crystal molecules; when the display panel 100 is an OLED display, the pixel unit 132 includes a light-emitting diode.

[0040] like Figure 2 As shown, the control unit 131 includes a control end, a first connection end and a second connection end; the first connection end of each control unit 131 is electrically connected to the data line 120 of the corresponding column, and the second connection end of each control unit 131 is connected to the input end of the corresponding pixel unit.

[0041] In this embodiment, the 3i-2nd column data line is electrically connected to the 3i+1st column data line, the 3i-1st column data line is electrically connected to the 3i+2nd column data line, and the 3ith column data line is electrically connected to the 3i+3rd column data line. That is to say: i takes an odd value; when i=1, the data line in the first column is connected to the data line in the fourth column, the data line in the second column is connected to the data line in the fifth column, and the data line in the third column is connected to the data line in the sixth column; when i=3, the data line in the seventh column is connected to the data line in the tenth column, the data line in the eighth column is connected to the data line in the eleventh column, and the data line in the ninth column is connected to the data line in the twelfth column; and so on. The connection relationship will not be repeated here.

[0042] like Figure 2 As shown, in the n-th row pixel circuit 130: the control ends of the 3i-2th column, 3i-1th column and 3i-th column control units are respectively connected to the 2n-1th row scan line, and the control ends of the 3i+1th column, 3i+2th column and 3i+3th column control units are respectively connected to the 2nth row scan line.

[0043] It should be noted that n and i in this embodiment are variables, N and M are constants, the value range of variable n is 1 to N, and the value range of variable i is 1 to For odd values ​​between , N and M are both positive integers greater than 1.

[0044] For example, for the 1st row of pixel circuits 130, the control ends of the 1st column control unit 131, the 2nd column control unit 131, the 3rd column control unit 131, the 7th column control unit 131, the 8th column control unit 131, the 9th column control unit 131, the 13th column control unit 131, the 14th column control unit 131, the 15th column control unit 131... are respectively connected to the 1st row of scan line 110, and the control ends of the 4th column control unit 131, the 5th column control unit 131, the 6th column control unit 131, the 10th column control unit 131, the 11th column control unit 131, the 12th column control unit 131... are respectively connected to the 2nd row of scan line 110.

[0045] In another embodiment of the present application, in the n-th row pixel circuit 130: the control terminals of the 3i-2 column, 3i-1 column and 3i column control units are respectively connected to the 2n-1th row scan line, and the control terminals of the 3i+1 column, 3i+2 column and 3i+3 column control units are respectively connected to the 2nth row scan line; the control terminals of the control units in this embodiment are connected to the scan lines in the same manner as in Figure 2On the contrary, for example: for the 1st row pixel circuit 130, the control ends of the 1st column control unit 131, the 2nd column control unit 131, the 3rd column control unit 131, the 7th column control unit 131, the 8th column control unit 131, the 9th column control unit 131, the 13th column control unit 131, the 14th column control unit 131, the 15th column control unit 131... are respectively connected to the 2nd row scan line 110, and the control ends of the 4th column control unit 131, the 5th column control unit 131, the 6th column control unit 131, the 10th column control unit 131, the 11th column control unit 131, the 12th column control unit 131... are respectively connected to the 1st row scan line 110.

[0046] In one embodiment, the pixel units in the 3m-2th column and the 3m+1th column are first color sub-pixels, the pixel units in the 3m-1th column and the 3m+2th column are second color sub-pixels, and the pixel units in the 3mth column and the 3m+3th column are third color sub-pixels; wherein,

[0047] It should be noted that in the above embodiments, color mixing is performed between two adjacent rows of pixels. In order to prevent the problem of color mixing of pixels of different colors, the colors of the pixel units in the same column are the same; the first color sub-pixel, the second color sub-pixel and the third color sub-pixel represent red sub-pixels, green sub-pixels and blue sub-pixels respectively.

[0048] In one embodiment of the present application, Figure 3 As shown, the control unit 131 includes: a switching transistor T1, the gate of the switching transistor serves as the control end of the control unit 131, the first end of the switching transistor T1 is connected to the data line 120, and the second end of the switching transistor T1 is connected to the pixel unit.

[0049] Figure 3 3a is a circuit diagram of the first pixel unit provided in an embodiment of the present application, wherein the pixel unit 132 includes: a storage capacitor Cc, a driving transistor T2 and a light-emitting diode OLED, wherein the first end of the storage capacitor Cc is connected to the output end Vo of the control unit 131, and the second end of the storage capacitor Cc is connected to the power supply end VDD; the control end of the driving transistor T2 is connected to the first end of the storage capacitor Cc, and the first end of the driving transistor T2 is connected to the second end of the storage capacitor Cc; the anode of the light-emitting diode OLED is connected to the second end of the driving transistor T2, and the cathode of the light-emitting diode OLED is grounded VSS.

[0050] In this embodiment, when the switch transistor T1 is in the on state, the storage capacitor Cc is charged by the data signal on the data line 120, and under the action of the driving voltage output by the power supply end, the driving transistor T2 outputs a corresponding driving current to drive the light emitting diode OLED to emit light.

[0051] Figure 3 3b is a circuit diagram of the second pixel unit provided in an embodiment of the present application, wherein the pixel unit 132 includes: a liquid crystal capacitor, wherein the pixel electrode of the liquid crystal capacitor is connected to the second end of the switching transistor T1; wherein the liquid crystal capacitor Cs is generally formed by a pixel electrode, a common electrode, and liquid crystal molecules between the pixel electrode and the common electrode, and data signals of different sizes are applied to the pixel electrode to rotate the liquid crystal molecules to different angles, thereby realizing brightness adjustment of the pixel unit 132.

[0052] In this embodiment, the pixel unit 132 further includes an energy storage capacitor Ct, and the pixel electrode of the energy storage capacitor Ct is connected to the second end of the switch transistor T1 to maintain the charging voltage.

[0053] Figure 4 The figure shows an example circuit diagram of a display panel provided by an embodiment of the present application. This embodiment takes the 2T1C OLED application as an example. The specific driving methods include:

[0054] (1) The first driving mode: N rows of scan lines are turned on row by row; the driving timing diagram is as follows Figure 5 As shown, the horizontal scan lines are turned on row by row, with G1 turned on first and S1 charging the sub-pixels in the first column. Then G2 is turned on and S4 charges the sub-pixels in the fourth column. The same applies to the other rows and columns. At resolutions such as UHD, the new DRD driver architecture provided in this embodiment reduces the number of driver chips by half (UHD generally has 12 drivers, while DRDs are 6, a reduction of half), enabling a display of 4K×2K×60Hz.

[0055] (2) The second driving mode: the 2n-1 scan line and the 2n scan line are turned on at the same time, and the 2n-1 scan line and the 2n+1 scan line are turned on line by line. The specific driving timing diagram is as follows: Figure 6 As shown, G1G2 is turned on at the same time, and the first row of sub-pixels in the 1st and 4th columns are charged at the same time. Then G3G4 is turned on at the same time, and the second row of sub-pixels in the 1st and 4th columns are charged at the same time. The same applies to other rows and columns. This architecture can achieve horizontal merging of two pixels simply by controlling the scan line opening method, cleverly transferring the row merging originally achieved by GateLine control to column merging, thereby realizing DLS drive mode (two-column pixel merging), which is compatible with display of 4K×2K×60Hz and 2K×2K×120Hz at UHD resolution.

[0056] (3) The third driving mode: the 4n-3rd scan line and the 4n-1st scan line are turned on at the same time, the 4n-2nd scan line and the 4nth scan line are turned on at the same time, and the 4n-3rd scan line and the 4n-2nd scan line are turned on line by line. The specific driving timing diagram is as follows: Figure 7As shown, when n=1, G1G3 is turned on at the same time, and the sub-pixels in the first row and the second row of the first column are charged at the same time. Then G2G4 is turned on at the same time, and the sub-pixels in the first row and the second row of the first column are charged. The same applies to other rows and columns, thereby realizing the DLG driving mode (two rows of pixels are combined); it is compatible with the display of 4K×2K×60Hz and 4K×1K×120Hz at UHD resolution.

[0057] (4) The fourth driving mode: the 4n-3rd scan line, the 4n-2nd scan line, the 4n-1th scan line and the 4nth scan line are turned on at the same time, and the 4n-3rd scan line and the 4n+1th scan line are turned on row by row. The specific driving timing diagram is as follows: Figure 8 As shown, when n=1, G1, G2, G3, and G4 are turned on at the same time, and the first two rows of sub-pixels in the first and fourth columns are charged at the same time; when the four scan lines are turned on at the same time, two of the scan lines realize the horizontal merging of two rows, and the row merging originally controlled by the other two scan lines is cleverly transferred to the column merging by this architecture, thereby realizing both DLG and DLS driving modes at the same time; at UHD resolution, the driving architecture of this embodiment supports DLG&S mode (two rows and two columns of pixels are merged at the same time), which can display 4K×2K×60Hz (UHD) and 2K×1K×240Hz (FHD) compatibility; special Timing, four rows are turned on at the same time, which can increase the refresh rate by four times, and has ultra-high refresh without cost increase. It can use existing driver chips in the industry, with strong universality and low implementation difficulty.

[0058] It can be seen that in this embodiment, under UHD resolution (4K×2K×60Hz working mode), the DRD driving architecture (2G1D) is used, that is, S1 charges two columns of sub-pixels in sequence, and the charging time for each row is as follows: Figure 1 The normal architecture (1G1D) is half of that, but when it enters FHD resolution (2K×1K×240Hz working mode), the charging time of each row will be the same as Figure 1 The standard architecture (1G1D) and FHD are the same, ensuring ample charging time and no charging issues. For laptops or MNT monitors, UHD resolution can be used for daily office work and watching movies, while FHD (Full High Definition) resolution and 240Hz high refresh rate mode can be used for esports gaming.

[0059] Figure 9 The figure shows a schematic diagram of the application of a display panel provided by an embodiment of the present application in a liquid crystal screen. The gray scale of the liquid crystal screen is divided into positive and negative. First, in high-definition display mode, if you want to charge Figure 9Effect, turn on G1, G3, G5, G7, G9... in sequence, charge all the pixels in the first column of a frame, then turn on G2, G4, G6, G8, G10... in sequence, charge all the pixels in the fourth column of a frame, S1 output only needs to switch the positive and negative polarity once in a frame, but the computer host and TV signal source transmit display data line by line, so the driver chip needs to store a frame of data before executing it, which is not supported by the current general chip and the cost of supporting it is very high; if Figure 5 The timing is turned on row by row, and the polarity will be reversed sub-pixel by sub-pixel, resulting in higher power consumption (but for a 27-inch UHD 60Hz MNT, which is small in size and has a low refresh rate, the power consumption will not be too high and is acceptable).

[0060] The optimized driving mode is to turn on the scan line 4n-3, the scan line 4n-2, the scan line 4n-1 and the scan line 4n row in sequence, such as Figure 10 As shown, when G1, G3, G2, G4, G6, G8, G5, and G7 are cycled, S1 polarity will cycle like ++----++, or ++----++++----++----++... This means four positive and four negative lines are switched at once, resulting in lower power consumption and requiring only two lines of display data storage, which is supported by current common chips. It should be noted that if driven by G1, G3, G5, G7, G2, G4, G6, and G8, four lines of display data must be stored, which is not supported by current common chips (a maximum of two lines). Horizontal polarity can only be +-+-+--+-+-+ (the output polarity of S1 and S2, and S3 and S4 simultaneously, must be opposite). This is discontinuous but balanced, and a six-column inverted display is possible.

[0061] In high refresh display mode, Figure 6 、 Figure 7 and Figure 8 The driving timing shown can also be applied to LCD displays. The S1 polarity does not switch in one frame, and the power consumption is low. The charging results are as follows: Figure 11 The horizontal polarity is also discontinuous but balanced between positive and negative every 12 columns.

[0062] In summary, the display panel provided by this application has at least the following beneficial effects:

[0063] 1. The present application electrically connects the 3i-2 column data line with the 3i+1 column data line, the 3i-1 column data line with the 3i+2 column data line, and the 3i column data line with the 3i+3 column data line, and connects the three sub-pixels in adjacent pixels to different scan lines on a pixel-by-pixel basis. By controlling the opening mode of the scan lines, two horizontal pixels can be merged, that is, a merged drive of two columns of display can be achieved.

[0064] 2. This application controls the 4n-3, 4n-2, 4n-1 and 4n scan lines to be turned on at the same time, and charges the two rows of sub-pixels of the two columns of pixel units at the same time, thereby realizing the driving mode of merging two columns of pixels and two rows of pixels.
