Abstract: A distance sensing substrate, a display device, a display system, and a resolution adjustment method are disclosed. The above distance sensing substrate includes a particle emitter for emitting a first particle beam to a viewer; a particle receiver for receiving the first particle beam reflected by the viewer; and a processing unit for obtaining an energy density of the emitted first particle beam and an energy density of the received first particle beam. The resolution of the display screen can be adjusted based on the viewing distance from the viewer to the display screen. When the viewing distance of the user is relatively large, the resolution of the display screen will be reduced appropriately, so as to reduce a power consumption of the display screen on the premise of ensuring a viewing effect of the user.

The polarity inversion driving method comprises a step of performing polarity inversion on groups of pixel units according to a preset period, wherein each group of pixel units comprises rows of pixel units sequentially arranged in a same column, and a gate on-state duration of the first row of pixel unit in each group of pixel units is longer than the gate on-state duration of the remaining rows of pixel units in the group of pixel units. Correspondingly, the present invention further provides a polarity inversion driving device for a liquid crystal display panel. According to the present invention, when N-dot inversion driving is performed on the liquid crystal panel, charging times of respective rows of pixel units in each group of pixel units are closer.
