Abstract

The present invention relates to a method for self-adaptively adjusting the brightness of a panel display screen, comprising: step a, start the panel, and a central processing system acquires environment information and time information; step b, a camera device acquires user face images, and the central processing system acquires user information Step c, the central processing system judges whether the flat panel can be used by the current user according to the user management index; step d, the central processing unit selects the corresponding flat panel screen brightness according to the current ambient light intensity, and compares the screen brightness according to the obtained user's face position and the flat panel distance The brightness of the selected flat panel screen is adjusted; step e, the central processing system determines the center position of the face according to the facial features; step f, the central processing system obtains the angle θ' of the plane formed by the center of the human face and the X axis and the Y axis, Determine the panel brightness adjustment parameters; so that the adjusted panel screen brightness meets the preset standard.

Description

technical field [0001] The invention relates to the field of flat panel display brightness, in particular to a method for adaptively adjusting the brightness of a flat panel display. Background technique [0002] Due to the advantages of small size and light weight, and the combination of multiple functions, tablet computers have already occupied a considerable proportion in the market. With the continuous improvement of its technology and software, it has become the main force of personal computers, mainly used in daily office, leisure and entertainment, and even online teaching. [0003] As tablet computers are gradually integrated into life, work and study, users often suffer from visual impairment due to incorrect posture, too close eyes, too long use time or too strong brightness when reading and using, especially for children. Using a tablet for too long not only affects eyesight, but also the blue light from the screen is toxic to children's skin. The adjustment of ...
