Display base plate and driving method and display device thereof

Abstract

The invention discloses a display base plate and a driving method and a display device of the display base plate, relating to the technical field display and aiming at reducing the power consumption of the display device. The display base plate is provided with multiple first light-transmitting areas distributed into an array, each first area is used as a sub-pixel, at least two adjacent sub-pixels form one pixel, all sub-pixels in each pixel correspond to backlights with different colors respectively, the display base plate also comprises multiple light shading structures corresponding to the sub-pixels one by one, and each light shading structure is used for adjusting the light ray transmitting rate of one sub-pixel. The power consumption of the display device can be reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate, a driving method thereof, and a display device. Background technique [0002] Currently, a commonly used color display device is a liquid crystal display, which includes a backlight module, an array substrate, a liquid crystal molecular layer, and a color filter substrate sequentially stacked. Among them, the backlight module is used to provide backlight, the array substrate is used to control the deflection state of liquid crystal molecules in the liquid crystal molecular layer, and the color filter substrate is used to selectively absorb and transmit light. [0003] The inventors of the present application found that the liquid crystal display with the above-mentioned structure has at least the following two disadvantages: on the one hand, because the color filter substrate selectively absorbs and transmits light, only a part of the light provided ...

Problems solved by technology

[0003] The inventors of the present application found that the liquid crystal display with the above-mentioned structure has at least the following two disadvantages: on the one hand, because the color filter substrate selectively absorbs and transmits light, only a part of the light provided by the backlight module can Through the color film substrate, the light utilization rate of the liquid crystal display is low. Therefore, in order to ensure the brightness of the liquid crystal display, the backlight module is required to have high power consumption, so that the power consumption of the liquid crystal display is relatively high.
