Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0019] see figure 1 As shown, according to the embodiment of the present invention, the control method of the display includes the following steps:

[0020] Step S10: acquiring temperature information of the display;

[0021] Step S20: According to the temperature information, it is judged whether the display needs to be adjusted in temperature;

[0022] If yes, perform step S30: adjust the brightness of the backlight of the display by changing the duty ratio of the pulse width modulation waveform.

[0023] By taking the temperature information of the display (such as the temperature of key components, including processor temperature, power supply temperature, screen temperature, etc.), the processor of the display can judge whether the temperature of the display needs to be adjusted...

Abstract

The invention discloses a display control method and a control system. The display control method comprises the steps that the temperature information of a display is acquired; according to the temperature information, whether the display needs temperature regulation is determined; and if the display needs temperature regulation, by changing the duty cycle of a pulse width modulation waveform, the backlight brightness of the display is regulated. According to the display control method and the control system, which are provided by the invention, the problems of high product cost and complex structure of heat dissipating of a liquid crystal display in the prior art are effectively solved.

Description

technical field [0001] The present invention relates to the technical field of displays, and in particular, to a control method and a control system for a display. Background technique [0002] Most of the industrial control liquid crystal displays in the prior art achieve the purpose of heat dissipation and lowering the operating temperature of the display according to the structural appearance design, for example, controlling the temperature of the display by using heat dissipation materials such as heat dissipation silica gel to avoid excessive temperature of the display. [0003] When the liquid crystal display is working, the temperature of the display power supply and the processor is too high due to the backlight being on for a long time and heating. There are two main disadvantages in terms of physical heat dissipation: [0004] 1) The structure and materials often complicate the structural design, the heat dissipation performance of the material is high, and the des...
