The projection area of the first color resistor 321 on the first polarizer 2 may be not overlapped 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 will not repeatedly filter the light entering the display device, which is beneficial to 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, an oxide of chromium, a black resin, or the like.

The second pixel electrode 45 is located at a side of the fourth substrate 46 facing the third substrate 41, and the second pixel electrode 45 may be arranged in an array.
In the column direction, each column of the first pixel electrodes 35 may be arranged offset from the corresponding column of the second pixel electrodes 45. In this way, two adjacent second pixel electrodes 45 are corresponding to one first pixel electrode 35 in the column direction, the first pixel electrode 35 and the first common electrode 33 form an electric field to enable the liquid crystal in the area 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, the two second pixel electrodes 45 and the second common electrode 43 form two different electric fields to enable the liquid crystal in the corresponding area to rotate by different angles, so that for the display area of each first pixel electrode 35, light rays can deflect by the same angle through the first sub-display panel 3, and deflect by two different angles through the second sub-display panel 4, so that the display area (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 projections of the center lines between the boundaries of the adjacent second pixel electrodes 45 on the first polarizer 2 may overlap with the projections of the center lines of the corresponding first pixel electrodes 35 on the first polarizer 2 in the row direction. The lengths of the two electric fields corresponding to the first pixel electrode 35 in the column direction are equal, that is, the areas of the display areas corresponding to each first pixel electrode 35 for displaying two different gray scales are equal, so that the display effect of the display device is improved.
In the column direction, the interval between the adjacent first pixel electrodes 35 and the interval between the adjacent second pixel electrodes 45 may be smaller than the first threshold, so that the interval area between the 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. The first threshold may be adjusted according to parameters such as the size of the display device.
Fig. 3 is a schematic view of another display panel 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 corresponding to the first pixel electrodes 35 and the second pixel electrodes 45, in the column direction, the first light-shielding sheets 322 are disposed in the interval regions of adjacent first color resists 321, the projection regions of the interval regions between the first pixel electrodes 35 and the interval regions between the second pixel electrodes 45 on the first polarizer 2 are located in the projection regions of the first light-shielding sheets 322 on the first polarizer 2, so that the light entering from the interval regions between the first pixel electrodes 35 and the interval regions between the second pixel electrodes 45 is shielded by the corresponding first light-shielding sheets 322, thereby reducing the probability of light leakage of the display panel. Since the light entering the interval region between the second pixel electrodes 45 is also blocked by the corresponding first light shielding film 322, the second sub-display panel 4 may not be provided with the corresponding color resist and light shielding film, so that the color resist and light shielding film may not be prepared when the second sub-display panel 4 is prepared, and the process flow for preparing the second sub-display panel 4 may be simplified.
The following describes a driving method of a display panel provided in an embodiment of the present application.
When driving the display panel for display, a progressive scanning manner may be employed. When scanning to the nth row and the mth column of the display panel, the second voltage of the second target pixel electrode corresponding to the target area can be determined according to the pre-display gray scale of the target area in the nth row and the mth column pixels in the first sub-display panel 3 and the first voltage of the first target pixel electrode corresponding to the target area, wherein 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 also 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 pixels may include a first display unit and a second display unit, where 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 determining the second voltage of the second target pixel electrode, the second voltage may be output to the second target pixel electrode corresponding to the nth row and mth column pixels.
Fig. 4 is a schematic diagram showing a relationship between a first pixel electrode and a second pixel electrode in any column in a display panel according to an embodiment of the present application, where, as shown in fig. 4, a first display unit and a second display unit of an N-1 th row of pixels in the display panel correspond to the first pixel electrode 35 of the N-1 th row, a first display unit of an N-1 th row of pixels corresponds to the second pixel electrode 45 of the N-1 th row, and a second display unit of an N-1 th row of pixels corresponds to the second pixel electrode 45 of the N-1 th row.
The first display unit and the second display unit of the nth row of pixels of the display panel correspond to the nth row first pixel electrode 35, the first display unit of the nth row of pixels corresponds to the nth row second pixel electrode 45, and the second display unit of the nth row of pixels corresponds to the n+1th row second pixel electrode 45.
When scanning to the N-1 th row of pixels of the display panel, the data voltage a may be outputted to the N-1 th row of the second pixel electrode 45 of the second sub-display panel 4, the N-1 th row of the second pixel electrode 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, the liquid crystal rotation angle a corresponding to the first display unit of the N-1 th row of pixels is made, then the liquid crystal rotation angle in the first sub-display panel 3 is determined according to the pre-display gray level 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 the first pixel electrode 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), and then the voltage is outputted to the N-1 th row of the first pixel electrode 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 association relationship between the pre-display gray scale and the first pixel electrode voltage and the second pixel electrode voltage can be stored, and only the corresponding first pixel electrode voltage and second pixel electrode voltage need to be searched according to the pre-display gray scale during driving. For example, the correspondence relation of the pre-display gray scale, the first pixel electrode voltage, and the second pixel electrode voltage may be stored in the feature table of the timing controller.
Fig. 5 is a schematic diagram of a feature table provided in an embodiment of the present application, as shown in fig. 5, each pre-display gray level may correspond to multiple sets of first pixel electrode voltages and second pixel electrode voltages, for example, when the pre-display gray level 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 C1, and so on.
When the pre-display gray level is L1, the voltage of the first pixel electrode may be A2, and the voltage of the second pixel electrode is A2; the voltage of the first pixel electrode can also be B2, and the voltage of the second pixel electrode is B2; the first pixel electrode voltage may also be C2, the second pixel electrode voltage C2, and so on.
Thus, after outputting the voltage to the first pixel electrode 35 of the N-1 row, the voltage of the corresponding second pixel electrode is queried in the feature table directly according to the pre-display gray scale of the second display unit of the N-1 row pixel and the voltage of the first pixel electrode 35 of the N-1 row pixel, and then the voltage is outputted to the second pixel electrode 36 of the N-1 row.
After outputting the voltage to the nth row second pixel electrode 36, the corresponding first pixel electrode voltage may be queried in the feature table according to the pre-display gray scale of the first display unit of the nth row pixel and the voltage of the nth row second pixel electrode 36, and then the voltage may be output to the nth row first pixel electrode.
After outputting the voltage to the nth row first pixel electrode 35, the corresponding first pixel electrode voltage may be queried in the feature table according to the pre-display gray scale of the second display unit of the nth row pixel and the voltage of the nth row first pixel electrode 35, and then the voltage may be output to the n+1th row second pixel electrode.
And so on, the display panel is lit row by row.
