Abstract

The invention relates to a head-mounted display device and a smear eliminating method. The head-mounted display device comprises a liquid crystal display screen, a screen driver, a backlight controller and a plurality of backlights; the backlights are distributed in multiple rows, and the screen driver scans a first part of an image of a frame of image to a first display area of the liquid crystal display screen; after scanning of the first part image is completed, the backlight controller controls the lightening state of each backlight in the first row of backlight at a preset time interval, the preset time interval is larger than the polarity overturning time of the liquid crystal display screen, and the lightening state control comprises the steps that the backlight controller sets the backlight brightness according to backlight control data, and the backlight brightness is set according to the polarity overturning time of the liquid crystal display screen, and the backlight brightness value is set of the backlight, or the backlight controller sets the the turn-off of the backlight according to the backlight control data, so the problem of smear of the liquid crystal display screen is solved, and the immersion of a user when using the head-mounted display equipment is enhanced.

Description

technical field [0001] The present application relates to the technical field of virtual reality, in particular to a head-mounted display device and a method for eliminating smear. Background technique [0002] Virtual reality (Virtual Reality, referred to as VR) head-mounted display devices generally use Active Matrix (Active Matrix) thin film transistor (referred to as TFT) liquid crystal display (Liquid Crystal Display, referred to as LCD), through the liquid crystal display A TFT is set on each pixel, which can control the light penetration rate, making the brightness brighter, the color richer, and the viewing area wider. [0003] Due to the high refresh rate required by the VR head-mounted display device, the processing time allocated to each frame of image is very limited. In related technologies, it takes time to flash a frame of image to the LCD screen. It takes time to wait for the polarity of the LCD screen to flip, and the LCD screen is only controlled by a sing...
