Liquid crystal display control method and system, and display device

摘要

Disclosed are liquid crystal display control method and system, and a display device. The liquid crystal display control method comprises: performing a decoding operation on input video signals to obtain data corresponding to respective pixels of a display panel; dividing the display panel into a plurality of display regions so that each display region corresponds to one or more light sources of a backlight source and a symmetric center of the one or more light sources is positioned such that an orthographic projection thereof on the display panel is coincided with a center of the corresponding display region; calculating a control signal for controlling display of each display region based on the data corresponding to pixels in the display region; redividing each display region into a plurality of subregions based on a light distribution in the display region and regulating the control signal for controlling the display of each subregion based on data corresponding to pixels in the subregion; and controlling the display panel and the backlight source based on the regulated control signals.

1. A liquid crystal display control method, comprising steps of:
performing a decoding operation on input video signals to obtain data corresponding to respective pixels of a display panel; dividing the display panel into a plurality of display regions, so that each display region corresponds to one or more light sources of a backlight source and a symmetric center of the one or more light sources is positioned such that an orthographic projection thereof on the display panel is coincided with a center of the corresponding display region; calculating a control signal for controlling display of each display region based on the data corresponding to pixels in the display region; redividing each display region into a plurality of subregions based on a light distribution in each display region so that as light-emitting angle varies, a brightness of light emitted from the respective light source is decreased gradually, and regulating the control signal for controlling display of each subregion based on data corresponding to pixels in the subregion; and controlling the display panel and the backlight source based on the regulated control signals.
