RGB Mini-LED field sequence backlight control system and method

Abstract

The invention provides an RGB Mini-LED field order backlight control system. The backlight control system comprises a video signal input module, a storage module, a data processing and control module, a panel driving display module, a backlight driving module and a backlight display module. According to the method, a deep learning model between the contrast ratio, the power consumption, the color splitting index and the system complexity and the number of the color RGB Mini-LED lamp bead backlight partitions is established, and the optimal backlight partition is obtained. According to the backlight control system disclosed by the invention, the field sequence partition image is processed, and a backlight control algorithm of adaptive partition primary color adjustment is adopted, so backlight driving signals are dynamically adjusted field by field and partition by partition, and color and brightness control of area backlight matched with field sequence display image information is realized.

Description

technical field [0001] The invention belongs to the field of liquid crystal display technical equipment, in particular to an RGB Mini-LED field sequential backlight control system and method. Background technique [0002] Liquid crystal display devices have been widely used in modern society. At present, liquid crystal panels realize image display mainly through a timing control module and a glass substrate under the control of a backlight module. The backlight module is composed of an array of lamp beads, and the brightness of the lamp beads is adjusted to control the light to pass through the color filter to realize the display of different color effects. Due to the existence of the color filter inside the glass substrate, the cost of the whole machine increases and the light efficiency decreases. The traditional time-mixed field sequential display does not require color filters, and the R / G / B LED color beads are turned on in a frame-by-field time-sharing to realize tempo...

Problems solved by technology

However, the traditional field sequential display scheme does not control and adjust the backlight of the partitions, nor does it study and quantify the scheme of the partitions. The relationship between power consumption and other performances also fails to consider the complexity of the implementation of the partition scheme. At the same time, it does not take into account the impact of the number of partitions on the color splitting of the field sequential display, so the display effect of the field sequential display device is not good.
