Abstract

The invention discloses a Mini-LED backlight drive control chip and system supporting breakpoint resume transmission, and belongs to the technical field of Mini-LED drive chip design. Aiming at the problem that the Mini-LED driver chip in the prior art cannot realize brightness adjustment and the display effect is poor, the present invention provides a Mini-LED backlight drive control chip and system that supports breakpoint resume transmission, and sets a data identification unit Identify and judge whether the Mini-LED lamp tube is abnormal, if the lamp tube normally receives the data input signal to realize the lamp tube driving, if the lamp tube is abnormal, it receives the breakpoint resume transmission input signal to realize the lamp tube drive; the present invention adds the function of breakpoint resume transmission, through The design of the chip can control the output refresh rate and improve the performance of the overall chip.

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-...
