Example Embodiment

[0058] The inventors of the present invention have discovered 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 Diode). Diode), each area is used as the smallest adjustment unit (or the smallest backlight structure unit) to be controlled and adjusted separately.

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

Abstract

Embodiments of the invention provide a backlight adjusting method and device, a backlight adjusting computing device, a display device and a storage medium. The method includes the following steps: determining a region of attention and a region of non-attention in an image on the basis of points of attention of a user in the image; and conducting adjustment with first precision on backlight brightness of the region of attention and conducting adjustment with second precision on backlight brightness of the region of non-attention. The method can realize contrast adjustment of the region of non-attention and more refined adjustment of the dynamic region of attention, better accords with attention situations of the user during practical applications, greatly improves the visual experience ofthe user, simplifies a control process, and reduces the power consumption while satisfying needs of the user.

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...
