Abstract

The invention relates to the technical field of display, and provides a backlight source control device and method and a display device. The backlight source control device comprises a driving detection assembly and a backlight control assembly. The driving detection assembly is used for detecting whether the display module gate driving circuit is in a scanning state; And the backlight control assembly is used for controlling the opening / closing of the backlight source according to the scanning state detected by the driving detection assembly. According to the invention, when the driving detection assembly detects that the display assembly is in the scanning state, the backlight source is turned on through the backlight control assembly; And when the driving detection assembly detects thatthe display assembly is in a non-scanning state, the backlight source is turned off through the backlight control assembly. Therefore, the image jitter condition of the display device under the low scanning frequency is avoided.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a backlight source control device, method and display device. Background technique [0002] Liquid crystal display (LCD) display devices can be applied to various electronic devices. As LCD display devices are more and more used in mobile devices such as mobile phones, LCD display devices have higher and higher requirements for their own energy consumption. Low energy consumption The LCD display device can greatly improve the standby time and battery life of mobile devices such as mobile phones. [0003] In the related art, the energy consumption of the display device is generally reduced by reducing the refresh frequency of the LCD display device. [0004] However, in the related art, when the refresh frequency of the LCD display device is lower than the resolution frequency of human eyes, the image of the LCD display device will vibrate, thereby affecting the experien...
