Abstract

The invention relates to the electronic communication technology field and particularly relates to a device and a method used for adjusting handset illumination brightness. Through adjusting a wave duty ratio, an average current of an electric torch can be adjusted through the wave duty ratio; when brightness of the electric torch is adjusted, wave signal frequency is unchanged, the time of a high level of wave pulses is changed, namely the conduction time of the electric torch is changed. The signal adjustment brightness is relatively equivalent to adjusting an average current of the torch, the current changes, so the power of the torch can be changed according to change of the wave duty ratio. According to the device and the method used for adjusting handset illumination brightness, brightness adjustment is realized through adjusting PWM waves, a user is enabled to select a relatively low power consumption mode according to actual situations and electric quantity of a handset, so not only can illumination demands be satisfied, but also the electric quantity can be saved, endurance time prolongation is facilitated, brightness of the electric torch is adjusted according to personal preference, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to a device and method for adjusting the illumination brightness of a mobile phone. Background technique [0002] With the rapid development of smart phones in recent years, the hardware configuration has become higher and higher. Most high-end smart phones are equipped with high-pixel cameras, and in order to improve the shooting experience of specific scenes, the cameras are equipped with a flash, another flash The purpose is that it can be used as a flashlight, that is, to keep the flashlight always on to realize the function of the flashlight lighting. Along with the development of science and technology, the application software program on the mobile phone constantly introduces the old and brings forth the new, and the mobile phone application on the Internet is of a great variety at present. After installing various applications on the mobile phone, there are...
