Abstract

The invention discloses a Mini-LED backlight driving control chip and system supporting breakpoint resume, and belongs to the technical field of Mini-LED driving chip design. In order to solve the problems that in the prior art, a Mini-LED driving chip cannot achieve brightness adjustment and is poor in display effect, the Mini-LED backlight driving control chip and system supporting breakpoint resume are provided, a data recognition unit is arranged to recognize and judge whether a Mini-LED lamp tube is abnormal or not, if the lamp tube, a data input signal is normally received to achieve lamp tube driving, and if the lamp tube is abnormal, a breakpoint is received and an input signal is transmitted continuously to drive the lamp tube; and the breakpoint resuming function is added, the output refresh rate can be controlled through the design of the chip, and the performance of the whole chip is improved.

Description

technical field [0001] The present invention relates to the technical field of Mini-LED driver chip design, and more specifically, relates to a Mini-LED backlight driver control chip and system supporting breakpoint resume transmission. Background technique [0002] With the increase of information acquisition channels, people's demand for display screens continues to increase. People are also pursuing better display effects in addition to displayed picture information. In this context, high-contrast, high-brightness displays can Bring users a more realistic display effect. Compared with other display methods, Mini-LED display can achieve the corresponding effect through backlight technology. After the improvement of traditional display, Mini-LED is a new type of LCD display with backlight display. The filter is separated, and then the backlight panel is partitioned, so that on the basis of color control, the brightness of different areas can be set. The emergence of Mini-...
