Abstract

The embodiment of the invention discloses a liquid crystal display device, a control method thereof, head-mounted display equipment and a medium. The control method of the liquid crystal display device comprises the steps that the state of each pixel of a display panel is acquired according to an input image data; according to the state of each pixel of the display panel, a display partition comprising pixels in a bright state and pixels in a dark state is obtained, and the obtained display partition serves as a target partition; according to the states of the pixels in the target partition, ahalo region is obtained, wherein the halo region comprises the pixels in the dark state in the target region; a first control signal is generated according to the halo region; a to-be-adjusted backlight partition is controlled according to the first control signal. According to the technical scheme, by obtaining the halo region, the to-be-adjusted backlight partition is adjusted, the area of thehalo region can be fixed, the flickering phenomenon that the halo is small sometimes or large sometimes is avoided, and a good display effect is achieved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and specifically relate to a liquid crystal display device and a control method thereof, a head-mounted display device, and a medium. Background technique [0002] Liquid Crystal Display (LCD for short) has the advantages of low radiation, small size, and low energy consumption, and is widely used in electronic products such as tablet computers, televisions, and mobile phones. The existing liquid crystal display device LCD uses a light-emitting diode (Micro Light Emitting Diode, Micro LED for short) array as a backlight source. When the light-emitting diode is a micro light-emitting diode Micro LED, it brings a higher dynamic range to the liquid crystal display device LCD. More optimized power consumption. [0003] The inventors have found through research that the backlight in the liquid crystal display device has a point diffusion effect, which will cause halos in the co...
