Embodiment Construction

[0058] The inventors of the present invention have found through research that the entire backlight area can be divided into m×n (m and n are both positive integers) mutually independent areas, and each area corresponds to one or several LEDs (Light-Emitting Diodes, which emit light). Diode), and each area is controlled and adjusted separately as the smallest adjustment unit (or the smallest backlight structural unit).

[0059] If the brightness of the smallest backlight structural unit is represented by Aij, i represents the number of rows, 1<

Abstract

Embodiments of the present disclosure provide a method for adjusting backlight for a display device, a device for adjusting backlight, a computing device, a display device, and a storage medium. The method includes: acquiring a displayed image of the display device; acquiring a gazed point of a user on the displayed image; determining a gazed area and an un-gazed area for a displayed image according to the gazed point; adjusting a brightness of the backlight for the gazed area with a first precision; and adjusting the brightness of the backlight for the un-gazed area with a second precision.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, the present invention relates to a backlight adjustment method, device, computing device, display device and storage medium. Background technique [0002] In the traditional backlight brightness adjustment technology, in most cases, it is only adjusted for the backlight area corresponding to the user's visual attention area on the displayed image. All R&D personnel focus on developing various algorithms to modify this area, while the non-focus area The corresponding backlight area is seldom adjusted, and even the adjustment usually only reduces the brightness of the backlight area in the non-focused area, or even turns it off. [0003] Although the non-concerned area is not the core area observed by the user, it is not the blind area of ​​the user's field of vision. Its brightness characteristics still affect the user's viewing experience. The overall display effect affec...
