Abstract

The invention relates to a display driving method and a display. The display driving method comprises the following steps: dividing a driving voltage range of the display into a plurality of voltage intervals; detecting the current feedback voltage of the display; determining a target feedback voltage according to the plurality of voltage intervals and the current feedback voltage; and determining a target driving voltage of the display according to the target feedback voltage to drive the display to display. The driving voltage range of the display is divided into the plurality of voltage intervals, the current feedback voltage of the display is detected, then the target feedback voltage is determined according to the plurality of voltage intervals and the current feedback voltage, and finally the target driving voltage of the display is determined according to the target feedback voltage so as to drive the display to display. The problem of false triggering of open circuit protection caused by step-by-step increase of the power supply voltage of the display can be solved, the feedback response speed is increased, and the stability of backlight driving is enhanced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display driving method and the display. Background technique [0002] At present, as consumers have higher requirements for TV display quality, many new display technologies have emerged. Among them, Mini LED technology has received extensive attention. Mini LED is mostly used in the backlight part of the display. Through the driving system, the fine control of the extremely small partition can be realized, and the display effect comparable to that of OLED can be achieved. In practical applications, the current HDR standard for image quality requires that the peak brightness of the display must reach a very high value (for example, above 1000 nits), and the local dimming (ie, Local Dimming) technology requires that the backlight can quickly follow the different brightness displayed on the screen. For example, the backlight needs to support instantaneous switching f...
