The present application is further described with reference to the accompanying drawings and optional embodiments.

As shown in FIG. 1 to FIG. 5, an embodiment of the present application discloses a display panel 200. The display panel 200 includes: a first substrate; multiple pixels 100, disposed on the first substrate, where the pixels include first pixels 110 and second pixels 120; multiple data lines, disposed on the first substrate; and multiple scan lines, disposed on the first substrate. The first pixels 110 and the second pixels 120 are connected to an n^th row of data line and an n^th row of scan line; the first pixels 100 each include a first primary pixel 111 and a first secondary pixel 113 that are disposed adjacently, and the second pixels 120 each include a second primary pixel 121 and a second secondary pixel 123 that are disposed adjacently; the first primary pixel 111 and the first secondary pixel 113 are connected to the n^th row of scan line and the n^th row of data line, and the second primary pixel 121 and the second secondary pixel 123 are connected to the n^th row of scan line and the n^th row of data line; and the first secondary pixel 113 is connected to a first pull-down circuit 115 used to pull down a charging voltage of the first secondary pixel 113, and the second secondary pixel 123 is connected to a second pull-down circuit 125 used to pull down a charging voltage of the second secondary pixel 123.

Relative to pixel architecture in FIG. 1 and FIG. 2, in the present application, the pixels include architecture of the first pixels 110 and the second pixels 120, and the first pixels 110 and the second pixels 120 are connected to a same row of data line and a same row of scan line. The first pixels 110 each are divided into the first primary pixel 111 and the first secondary pixel 113, the second pixels 120 each are divided into the second primary pixel 121 and the second secondary pixel 123, the first pixels 110 each include the first primary pixel 111 and the first secondary pixel 113 having different charging voltages, and the second pixels 120 each include the second primary pixel 121 and the second secondary pixel 123 having different charging voltages. In this way, the pixels connected to the same row of data line and the same row of scan line may correspond to two different electrical potentials according to needs, and cooperate with a Gamma voltage to perform color cast compensation, so that large viewing angle color cast of the display panel 200 especially the display panel 200 in a vertical alignment display (VA) mode can be effectively resolved. Compensation can be flexibly performed for non-uniform luminance and color cast for four different corresponding electrical potentials according to needs, so that the display panel 200 has a very good display effect.

As shown in FIG. 5, in an embodiment, the first secondary pixel 113 includes a first secondary pixel electrode 114; the first pull-down circuit 115 includes a first discharging switch T3 and a first discharging capacitor C1; the second secondary pixel 123 includes a second secondary pixel electrode 124; the second pull-down circuit 125 includes a second discharging switch T6 and a second discharging capacitor C2; a control terminal of the first discharging switch T3 is connected to an (n+1)^th row of scan line, a source terminal is connected to the first secondary pixel electrode 114, and a drain terminal is connected to the first discharging capacitor C1; and a control terminal of the second discharging switch T6 is connected to the (n+1)^th row of scan line, a source terminal is connected to the second secondary pixel electrode 124, and a drain terminal is connected to the second discharging capacitor C2.

In this solution, the first primary pixel 111 includes a first primary pixel electrode 112, and the second primary pixel 121 includes a second primary pixel electrode 122. The first secondary pixel electrode 114 is discharged by using the first discharging capacitor C1, and the second secondary pixel electrode 124 is discharged by using the second discharging capacitor C2. The same row of scan line is connected to the first secondary pixel electrode 114 and the second secondary pixel electrode 124 by using the first discharging switch T3 and the second discharging switch T6, so that the same row of scan line may correspond, according to needs, to the first secondary pixel electrode 114 whose electrical potential is different from an electrical potential of the first primary pixel electrode 112 and the second secondary pixel electrode 124 whose electrical potential is different from an electrical potential of the second primary pixel electrode 122, and even the first secondary pixel electrode 114 and the second secondary pixel electrode 124 may correspond to different electrical potentials according to needs, so that bright pixels and dark pixels are flexibly set, to cooperate with other color cast compensation operations including a Gamma voltage, thereby effectively resolving large viewing angle color cast of the display panel 200. Certainly, the first discharging switch T3 and the second discharging switch T6 may not be used, that is, a discharging time of a discharging capacitor may not be controlled. Specifically, the first secondary pixel includes the first secondary pixel electrode, the first pull-down circuit includes the first discharging capacitor, the second secondary pixel includes the second secondary pixel electrode, the second pull-down circuit includes the second discharging capacitor, the first secondary pixel electrode is connected to the first discharging capacitor, and the first secondary pixel electrode is connected to the second discharging capacitor. However, a relatively high requirement is imposed on the first discharging capacitor C1 and the second discharging capacitor C2, to achieve a preset luminance difference. In addition, the control terminal of the first discharging switch T3 and the control terminal of the second discharging switch T6 may be connected to the n^th row of scan line, the (n+1)^th row of scan line, or another row of scan line.

In an embodiment, the first substrate includes a common electrode wire; the first secondary pixel electrode 114 and the common electrode wire partially overlap to form the first discharging capacitor C1; and the second secondary pixel electrode 124 and the common electrode wire partially overlap to form the second discharging capacitor C2.

In this solution, the n^th row of scan line, the (n+1)^th row of scan line, or another row of scan line may be used to control the first discharging capacitor C1 and the second discharging capacitor C2 to discharge the first secondary pixel electrode 114 and the second secondary pixel electrode 124, so that the first pixels 110 each include the first primary pixel 111 and the first secondary pixel 113 having different electrical potentials, and the second pixels 120 each include the second primary pixel 121 and the second secondary pixel 123 having different electrical potentials. Based on this architecture, it helps to resolve the large viewing angle color cast of the display panel 200, and an optional display effect is achieved.

In an embodiment, a capacitance of the first discharging capacitor C1 is different from a capacitance of the second discharging capacitor C2. In this solution, because the capacitance of the first discharging capacitor is different from the capacitance of the second discharging capacitor C2, when controlled by a same scan line and receiving a same data signal, the first secondary pixel 113 and the second secondary pixel 123 have different luminance, so that for the same scan line and the same data signal, pixel electrodes of the first pixels 110 and the second pixels 120 may include at least three different voltage levels, and compared with pixels including two voltage levels, bright pixels and dark pixels can be set more flexibly, and it helps to resolve large viewing angle color cast of the display panel 200. In addition, because a voltage level is adjusted more flexibly, a same data signal may be presented in different luminance display effects, so that a same data line and a same scan line drive two different pixels, that is, pixel resolution is doubled when the scan line and the data line is not changed.

For example, the n^th row of data line receives a data signal having grayscale luminance (200, 200, 200), according to the architecture of this solution, the first pixels 110 may be presented as images corresponding to the grayscale luminance (200, 200, 200) and grayscale luminance (198, 198, 198), and the second pixels 120 may be presented as images corresponding to the grayscale luminance (200, 200, 200) and the grayscale luminance (198, 198, 198). On the basis of setting an appropriate capacitance and performing appropriate signal processing, when the data line signal is not changed, resolution of the data signal may be doubled in terms of a display effect, thereby indirectly improving resolution.

In an embodiment, a pull-down effect of the first pull-down circuit 115 is different from a pull-down effect of the second pull-down circuit 125. In this solution, because the pull-down effect of the first pull-down circuit 115 is different from the pull-down effect of the second pull-down circuit 125, when controlled by a same scan line and receiving a same data signal, the first secondary pixel 113 and the second secondary pixel 123 have different luminance, so that for the same scan line and the same data signal, luminance of the first pixels 110 is different from luminance of the second pixels 120. Therefore, when the scan line and the data line are not changed, resolution of the pixels is doubled, and when the data signal is not changed, according to the pixel structure in this solution, resolution of a same image is improved from A resolution to 2A resolution. Particularly, when a low-resolution image is viewed, the image can be viewed more clearly by using the display panel 200 of this solution. In this solution, not only the large viewing angle color cast is improved, but also under same resolution, a single-row scanning time in this solution is increased, a charging time is increased, and manufacturing costs of the display panel 200 are reduced. Luminance of pixels at two sides is different, and pixels at each side include primary pixels and secondary pixels having different luminance, so that color cast is further improved, and design space of the display panel 200 and design freedom of the display panel 200 are improved.

In an embodiment, the first primary pixel includes a first primary pixel electrode, and the second primary pixel includes a second primary pixel electrode; the first secondary pixel includes a first secondary pixel electrode, and the second secondary pixel includes a second secondary pixel electrode; a pattern of the first primary pixel electrode 112 is different from a pattern of the second primary pixel electrode 122; and a pattern of the first secondary pixel electrode 114 is different from a pattern of the second secondary pixel electrode 124.

In this solution, the pattern of the first primary pixel electrode 112 is different from the pattern of the second primary pixel electrode 122, the pattern of the first secondary pixel electrode 114 is different from the pattern of the second secondary pixel electrode 124, different domains may be set, and an aperture ratio of the first secondary pixel electrode 114 may be the same as or different from an aperture ratio of the second secondary pixel electrode 124. When controlled by a same scan line and receiving a same data signal, the first primary pixel 111, the second primary pixel 121, the first secondary pixel 113, and the second secondary pixel 123 have different voltages and different luminance, so that color cast of the display panel 200 is further improved, design space and design freedom of the display panel 200 are improved, a single-row scanning time is increased, and a charging time is increased. The first primary pixel electrode 112 and the second primary pixel electrode 122 may be made of different materials, or may be made by using different processes, so that an aperture ratio of the first primary pixel electrode 112 is different from an aperture ratio of the second primary pixel electrode 122.

In an embodiment, the first primary pixel 111 includes a first primary switch T1, the first secondary pixel 113 includes a first secondary switch T2, the second primary pixel 121 includes a second primary switch T4, and the second secondary pixel 123 includes a second secondary switch T5; a leakage current of the first primary switch T1 is different from a leakage current of the second primary switch T4; and a leakage current of the first secondary switch T2 is different from a leakage current of the second secondary switch T5.

In this solution, the leakage current of the first primary switch T1 is different from the leakage current of the second primary switch T4, so that a final charging voltage of the first primary pixel 111 is different from a final charging voltage of the second primary pixel 121. In addition, when an aperture ratio of the display panel 200 is not affected, the luminance of the first primary pixel 111 is different from the luminance of the second primary pixel 121. The leakage current of the first secondary switch T2 is different from the leakage current of the second secondary switch T5, so that a final charging voltage of the first secondary pixel 113 is different from a final charging voltage of the second secondary pixel 123. In addition, when the aperture ratio of the display panel 200 is not affected, the luminance of the first secondary pixel 113 is different from the luminance of the second secondary pixel 123. In this way, under the control of a same row of data line and a same row of scan line, the pixels may include pixel electrodes having four different electrical potentials. Based on such flexible setting of bright pixels and dark pixels, it helps to improve color cast of the display panel 200, the design space and the design freedom of the display panel 200 are improved, a single-row scanning time of the display panel 200 is increased, and a charging time of the pixels is increased.

In an embodiment, the first secondary pixel 113 includes a first secondary pixel electrode 114; the second secondary pixel 123 includes a second secondary pixel electrode 124; the first pull-down circuit 115 includes a first pull-down resistor, and the second pull-down circuit 125 includes a second pull-down resistor whose resistance is different from a resistance of the first pull-down resistor; one end of the first pull-down resistor is connected to the first secondary pixel electrode 114, and the other end is connected to a common electrode wire or an (n+1)^th row of scan line; and one end of the second pull-down resistor is connected to the second secondary pixel electrode 124, and the other end is connected to the common electrode wire or the (n+1)^th row of scan line.

In this solution, the first pull-down resistor and the second pull-down resistor are used, so that pull-down effects are different. The resistors are relatively cheap and it is convenient for manufacturing in an actual operation process. The first pull-down resistor and the second pull-down resistor have different resistances, so that the first secondary pixel electrode 114 and the second secondary pixel electrode 124 achieve different charging luminance. In this solution, one end of the first pull-down resistor may be connected to the first secondary pixel electrode 114, the other end may be connected to the common electrode wire or another row of scan line, one end of the second pull-down resistor may be connected to the second secondary pixel electrode 124, and the other end may be connected to the common electrode wire or another row of scan line.

In addition, a larger resistance of a resistor indicates a smaller aperture ratio. Correspondingly, a larger resistance indicates a more obvious pull-down effect of luminance of a secondary pixel electrode, and a smaller aperture ratio indicates a greater pull-down effect of the luminance of the secondary pixel electrode. In this way, they are supplementary to each other. When a resistance difference between resistors is relatively small, aperture ratios may be used as a supplement, to achieve a relatively great luminance difference.
