Abstract

The invention discloses a brightness control method and a brightness control device, belonging to the field of liquid crystal displays. The brightness control method comprises the steps of: acquiring a temperature value acquired by a first driving integrated circuit IC, and detecting whether the temperature value reaches a predetermined threshold value; and transmitting a control signal to a second driving IC if the temperature value reaches the predetermined threshold value. Whether the temperature value reaches the predetermined threshold value is detected through acquiring the temperature value acquired by the first driving, and the control signal is transmitted to the second driving IC if the temperature value reaches the predetermined threshold value; the problems that service life of circuit devices and backlight membrane materials in electronic equipment is shortened because a backlight source produces overhigh temperature due to overhigh power is solved; and the effects of monitoring the temperature produced by the backlight source timely, controlling a backlight circuit so that the temperature is kept below the predetermined threshold value, and prolonging the service life of the circuit elements and the backlight membrane materials in the electronic equipment are achieved.

Description

technical field [0001] The present disclosure relates to the field of liquid crystal display, in particular to a brightness control method and device. Background technique [0002] As people prefer large-screen mobile terminals, the display screens of mobile terminals become larger and higher in resolution. [0003] When the display screen of a mobile terminal becomes larger, the transmittance of the display screen itself will become worse. In order to improve the influence of the decrease of the transmittance on the display effect of the display screen, related technologies increase the brightness of the display screen by increasing the number of LEDs (Light Emitting Diodes, light emitting diodes) in the backlight circuit and increasing the luminous efficiency of the LEDs. However, in actual use, it is found that after the number of LEDs is increased and the luminous efficiency of the LEDs is increased, the heat emitted by the backlight circuit is very large, and the surro...
