Illumination method and illumination device applied to mobile terminal

Abstract

The invention relates to an illumination method and an illumination device applied to a mobile terminal. The illumination device applied to the mobile terminal comprises an instruction receiving unit, an LCD shutdown unit and an LED starting unit, wherein the instruction receiving unit is used for receiving a starting instruction for starting an illumination function of an LCD display module, the LCD shutdown unit is used for stopping data connection between the illumination device and an LCD driver display module and stopping power supply for the LCD driver display module according to the starting instruction, and the LED starting unit is used for starting the LCD driver display module and continuously performing power supply for the LCD driver display module according to the starting instruction. According to the illumination method and the illumination device applied to the mobile terminal, the data connection between the illumination device and the LCD driver display module and power supply for the LCD driver display module are stopped when the illumination function of the LCD display module is started, meanwhile work enabling and power supply for the LCD driver display module are kept, the purposes of efficient illumination and energy and electricity saving are achieved, and user experience degree is high.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a lighting method and a lighting device applied to a mobile terminal. Background technique [0002] Most mobile phones currently on the market have a flashlight lighting function, and its working principle is to integrate high-brightness light-emitting diodes in the mobile phone to form a miniature flashlight. Mobile phone users can use the lighting function of this mini flashlight to illuminate in dark environments. This function is both practical and convenient, and is very popular among consumers. [0003] With the gradual development of 3G networks and smart phones, the functions of mobile phones are becoming more and more abundant. Mobile phones with larger LCD displays of 2.8 inches and above have become mainstream. According to the current market demand, an LCD display with a size between 3.5 inches and 5 inches will be the mainstream display size speci...

Problems solved by technology

If the mobile phone user only needs to use the light emitted by the LCD display screen to illuminate, then the power consumption consumed by the display page circuit composed of the mobile phone CPU, the LCD driver chip and the LCD panel is wasted in vain, that is to say, the display The power consumed by the page circuit does not make any contribution to the user's lighting needs, and the power consumption of this part of the circuit causes a waste of power

[0007] 2. The reason why the lighting efficiency is not high: When the mobile phone user lights up the LCD screen to illuminate, the LCD screen will display a certain menu display page of the mobile phone menu. Because these menu display pages are blocked, the display brightness must not show pure The display brightness of the white background page is high, so the lighting efficiency of the menu display page is lower than that of the pure white background page
