Abstract

The invention relates to a backlight driving system and a display terminal, and the system comprises a brightness obtaining unit which is used for obtaining a plurality of brightness values corresponding to different backlight areas; the brightness processing unit is used for determining a plurality of backlight driving signals according to the plurality of brightness values, and the duty ratio of each backlight driving signal is associated with at least one brightness value in the plurality of brightness values; and the driving output unit is used for outputting the plurality of backlight driving signals to a display panel so as to drive the display panel to display. The backlight driving signals are determined by acquiring the brightness of the different backlight areas, the duty ratio of each backlight driving signal is associated with at least one brightness, the backlight driving signals are output to drive the display panel to display, the problem that the display brightness of the different backlight areas is inconsistent can be solved, and the display brightness of the display panel is improved. The brightness of different backlight areas is matched, the display effect of the display panel is optimized, and the watching experience is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a backlight driving system and a display terminal. Background technique [0002] With the development of technology, organic electroluminescence (Light-Emitting Diode, LED) display technology is more and more widely used. [0003] In the related art, when the Narrow Border (NB) display screen uses the under-screen camera technology, a separate one or more small backlights need to be provided below the camera, so as to provide a separate backlight source for the display area at the camera. However, due to the different backlight film materials and LED driving schemes, the optical characteristics of the backlight in different regions and the conversion efficiency of LED driving are different, which in turn leads to the problem that the brightness of the small backlight area at the camera is inconsistent with the brightness of the main backlight area around the camer...
