The first color resists 321 may be B resists, G resists, R resists, or the like, and the first light-shielding sheets 322 may be made of chrome, chrome oxide, black resin, or the like.

The projection area of the first color resistor 321 on the first polarizer 2 may not coincide with the projection area of the second color resistor 421 on the first polarizer 2, so that the first color resistor 321 and the second color resistor 421 do not repeatedly filter the light entering the display device, which is beneficial for the display of the display device.
The second color resist 421 may be a B color resist, a G color resist, an R color resist, or the like, and the material of the second light-shielding sheet 422 may be chromium, chromium oxide, black resin, or the like.

In the column direction, the first pixel electrode 35 of each column may be arranged to be misaligned with the second pixel electrode 45 of the corresponding column. Thus, one first pixel electrode 35 corresponds to two adjacent second pixel electrodes 45 in the column direction, an electric field is formed between the first pixel electrode 35 and the first common electrode 33 to enable liquid crystals in a region corresponding to the first pixel electrode 35 to rotate by a certain angle, if different voltages are output to the two adjacent second pixel electrodes 45, two different electric fields are formed between the two second pixel electrodes 45 and the second common electrode 43 to enable liquid crystals in the corresponding region to rotate by different angles, so that for the display region of each first pixel electrode 35, light can be deflected by the same angle through the first sub-display panel 3, and can be deflected by two different angles through the second sub-display panel 4, so that the display region (corresponding to two display units) corresponding to each first pixel electrode 35 can display two different gray scales in the column direction.
In the column direction, the projection of the center line between the boundaries of the adjacent second pixel electrodes 45 on the first polarizer 2 may overlap the projection of the center line of the corresponding first pixel electrode 35 in the row direction on the first polarizer 2. Thus, the lengths of the two electric fields corresponding to one first pixel electrode 35 in the column direction are equal, that is, the areas of the display regions corresponding to each first pixel electrode 35 and used for displaying two different gray scales are equal, so as to improve the display effect of the display device.
In the column direction, the interval between the adjacent first pixel electrodes 35 and the interval between the adjacent second pixel electrodes 45 may both be smaller than the first threshold, so that the interval area between two electric fields formed by the first pixel electrodes 35 and the corresponding adjacent second pixel electrodes 45 is smaller, and the area of the display area corresponding to the first pixel electrodes 35 is larger, which is beneficial to the improvement of the aperture ratio of the display device.

Fig. 3 is a schematic structural diagram of another display panel provided in the embodiment of the present application in the column direction, as shown in fig. 3, the first color resist layer 32 of the first sub-display panel 3 includes a plurality of first color resists 321 disposed at intervals and corresponding to the first pixel electrodes 35 and the second pixel electrodes 45, in the column direction, a first light shielding sheet 322 is disposed in an interval region adjacent to the first color resist 321, a projection region of the interval region between the first pixel electrodes 35 and the interval region between the second pixel electrodes 45 on the first polarizer 2 is located in a projection region of the first light shielding sheet 322 on the first polarizer 2, so that light entering from the interval region between the first pixel electrodes 35 and the interval region between the second pixel electrodes 45 is shielded by the corresponding first light shielding sheet 322, thereby reducing the probability of light leakage of the display panel. Since the light entering the spacing region between the second pixel electrodes 45 is also blocked by the corresponding first light-shielding sheet 322, the corresponding color resistor and light-shielding sheet may not be disposed in the second sub-display panel 4, and thus, the color resistor and light-shielding sheet may not be required to be prepared when the second sub-display panel 4 is prepared, thereby simplifying the process flow of preparing the second sub-display panel 4.
The following describes a driving method of a display panel provided in an embodiment of the present application.
When the display panel is driven to display, a progressive scanning mode can be adopted. When scanning to the nth row and mth column of the display panel, the second voltage of the second target pixel electrode corresponding to the target area may be determined according to the pre-display gray scale of the target area in the nth row and mth column of pixels in the first sub-display panel 3 and the first voltage of the first target pixel electrode corresponding to the target area, where M, N is a positive integer.
The first target pixel electrode may be the first pixel electrode 35, and the corresponding second target pixel electrode is the second pixel electrode 45; the first target pixel electrode may be the second pixel electrode 45, and the corresponding second target pixel electrode is the first pixel electrode 35.
The nth row and mth column of pixels may include a first display unit and a second display unit, the first display unit and the second display unit correspond to the same first pixel electrode 35 and different second pixel electrodes 45, and the target area is the first display unit or the second display unit.
After the second voltage of the second target pixel electrode is determined, the second voltage may be output to the second target pixel electrode corresponding to the nth row and mth column of pixels.
Fig. 4 is a schematic diagram illustrating a relationship between a first pixel electrode and a second pixel electrode in any column in a display panel provided in the embodiment of the present application, and as shown in fig. 4, a first display unit and a second display unit of an N-1 th row of pixels of the display panel both correspond to an N-1 th row of first pixel electrodes 35, a first display unit of an N-1 th row of pixels corresponds to an N-1 th row of second pixel electrodes 45, and a second display unit of an N-1 th row of pixels corresponds to an N-1 th row of second pixel electrodes 45.
The first display unit and the second display unit of the nth row of pixels of the display panel correspond to the first pixel electrode 35 of the nth row, the first display unit of the nth row of pixels corresponds to the second pixel electrode 45 of the nth row, and the second display unit of the nth row of pixels corresponds to the second pixel electrode 45 of the (N + 1) th row.
When scanning to the N-1 th row of pixels of the display panel, the data voltage a may be first output to the N-1 th row of second pixel electrodes 45 of the second sub-display panel 4, the N-1 th row of second pixel electrodes 45 and the common electrode (i.e., the second common electrode 43, which is a fixed voltage) of the second sub-display panel 4 form an electric field, so that the liquid crystal rotation angle a corresponding to the first display unit of the N-1 th row of pixels is determined, then the liquid crystal rotation angle in the first sub-display panel 3 is determined according to the pre-display gray scale G of the first display unit of the N-1 th row of pixels and the liquid crystal rotation angle a in the second sub-display panel 4, then the voltage of the N-1 th row of first pixel electrodes 35 of the first sub-display panel 3 is determined according to the liquid crystal rotation angle in the first sub-display panel 3 and the voltage of the common electrode (i.e., the first common electrode 33, which is a fixed voltage) of the first sub-display panel 3, and then the voltage is output to the N-1 th row of first pixel electrodes 35.
The gray scale displayed by the display panel is determined by the rotation angle of the liquid crystal in the first sub-display panel 3 and the rotation angle of the liquid crystal in the second sub-display panel 4. Since the voltages of the first common electrode 33 and the second common electrode 43 are fixed voltages, that is, the display gray scale is determined by the voltage of the first pixel electrode 35 and the voltage of the second pixel electrode 45, the correlation between the pre-display gray scale and the voltages of the first pixel electrode and the second pixel electrode can be stored, and the corresponding voltages of the first pixel electrode and the second pixel electrode need only be searched according to the pre-display gray scale during driving. For example, the correspondence relationship between the pre-display gray scale, the first pixel electrode voltage, and the second pixel electrode voltage may be stored in a feature table of the timing controller.
Fig. 5 is a schematic diagram of a feature table provided in the embodiment of the present application, and as shown in fig. 5, each pre-display gray scale may correspond to a plurality of sets of first pixel electrode voltages and second pixel electrode voltages, for example, when the pre-display gray scale is L0, the first pixel electrode voltage may be A1, and the second pixel electrode voltage is A1; the first pixel electrode voltage may also be B1, and the second pixel electrode voltage is B1; the first pixel electrode voltage may also be C1, the second pixel electrode voltage may be C1, and so on.
When the pre-display gray scale is L1, the voltage of the first pixel electrode may be A2, and the voltage of the second pixel electrode is A2; the first pixel electrode voltage may also be B2, and the second pixel electrode voltage is B2; the first pixel electrode voltage may also be C2, the second pixel electrode voltage may be C2, and so on.
Thus, after outputting the voltage to the first pixel electrode 35 of the N-1 th row, the voltage of the corresponding second pixel electrode can be directly looked up in the de-characterization table according to the pre-display gray scale of the second display unit of the pixel of the N-1 th row and the voltage of the first pixel electrode 35 of the N-1 th row, and then the voltage is output to the second pixel electrode 36 of the N-1 th row.
After outputting the voltage to the second pixel electrode 36 in the nth row, the corresponding first pixel electrode voltage may be looked up in the de-characterization table according to the pre-display gray scale of the first display unit of the pixel in the nth row and the voltage of the second pixel electrode 36 in the nth row, and then the voltage is output to the first pixel electrode in the nth row.
After outputting the voltage to the first pixel electrode 35 in the nth row, the corresponding first pixel electrode voltage may be looked up in the de-characterization table according to the pre-display gray scale of the second display unit of the pixel in the nth row and the voltage of the first pixel electrode 35 in the nth row, and then the voltage is output to the second pixel electrode in the (N + 1) th row.
And so on, lighting up the display panel row by row.
