Abstract

The present application is applicable to the field of LED driving technology, and provides an LED array driving method, a display array driving device and terminal equipment, wherein the LED array driving method includes: respectively inputting row scanning signals and column data signals to the LED array for addressing; If the current number of consecutive addressing reaches the threshold, the addressing is stopped, and the LED array is input with a working voltage to light up the LED array; when the duration of inputting the working voltage to the LED array reaches the point corresponding to the continuous addressing When the sum of the on-time durations is reached, the input of the operating voltage to the LED array is stopped. In this embodiment of the present application, the addressing operation is performed on at least one subfield, the backlight is not turned on during the addressing time of each subfield, and the backlight is turned on only during the non-addressing time of each subfield, so that there is enough time for the entire array. Addressing is performed so that the lighting of the backlight can be performed normally, and the modulation efficiency is improved.

Description

technical field [0001] The present application belongs to the technical field of LED driving, and in particular, relates to an LED array driving method, a display array driving device and terminal equipment. Background technique [0002] The display object in the display system is usually a display array, which is formed by splicing multiple display sub-arrays, each display sub-array is composed of a large number of display modules, and each display module includes LEDs and their control circuits. In the existing control method of the display system, if there is not enough time to address the entire array, an error occurs in the control logic, thereby affecting the subsequent lighting process, resulting in low grayscale accuracy. SUMMARY OF THE INVENTION [0003] In view of this, embodiments of the present application provide an LED array driving method, a display array driving device, and a terminal device, so as to solve the problem of low grayscale accuracy of the exist...
