example 1

[0035] This example aims to overcome the problems and defects of using photosensitive devices to save power in related technologies, and provides a solution to effectively prolong the standby time and battery life of products and improve user experience in solar terminal products.

[0036] In this example, the solar terminal includes the following modules: a baseband processing chip, a solar charging circuit, and a solar panel.

[0037] The basic principle is: the solar panel converts light energy into electrical energy and stores it in the battery through the solar charging circuit. The working current of the solar charging circuit is related to the intensity of the external light. When the ambient light is weak, the working current is small. Taking a solar panel of about 54mmX53mm as an example (the area is equivalent to the back area of ​​a conventional flip phone), the data shown in Table 1 are obtained through actual measurement under various light intensities:

example 2

[0047] figure 2 It is a schematic flowchart of the backlight adjustment method according to Example 2 of the present invention. Such as figure 2 As shown, the method includes the following steps:

[0048] Step S202, the terminal enters the standby state, and the keyboard backlight and LCD backlight are turned off;

[0049] Step S204, judging whether there is a wake-up event such as key operation or incoming call, if yes, go to step S206; if not, go to step S202;

[0050] Step S206, if an event occurs to wake up the terminal, the terminal collects the current working current of the solar charging circuit, wherein the solar charging circuit is located in the terminal;

[0051] Step S208, comparing the current working current value of the charging circuit with the preset current value, a list is preset in the software, and according to the current working current value of the charging circuit, it is judged that the value falls within the range of the preset list;

[0062] Figure 5 It is a schematic structural diagram of a terminal according to Example 3 of the present invention. Such as Figure 5 As shown, the terminal includes: a main control chip 502 (equivalent to the backlight adjustment circuit 34 and the current collection circuit 32 ), a solar charging circuit 504 (equivalent to the solar charging circuit 30 ), and a backlight circuit 506 .

[0063] The main control chip 502 collects the working current of the solar charging circuit, and controls the brightness level of the backlight circuit 506 after comparing with the preset value. The backlight circuit 506 includes a keyboard backlight circuit, an LCD backlight circuit and an indicator light circuit. These backlight circuits can be set to a certain brightness level among several brightness levels by sending control signals from the main control chip 502 as required.

Abstract

The invention provides a method for adjusting backlight of a terminal and the terminal. The method includes that when a backlight circuit of a schedule event trigger terminal displays backlight, the terminal collects a current working current value, the working current value is a working current value of a solar charging circuit of the terminal, and backlight brightness of the backlight circuit is adjusted by the terminal according to the working current value. By adopting the technical scheme, problems of short standby time, high terminal cost, short battery service life and the like caused by terminal backlight in related technologies are solved, so that cost is not increased while standby time of the terminal is effectively prolonged, battery service life is prolonged, and user experience is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a terminal backlight adjustment method and the terminal. Background technique [0002] In recent years, countries around the world have implemented energy policies for sustainable development. As a green energy source, solar energy will be widely used in various terminal products such as tablet computers, mobile phones, Mp3, and Mp4. In order to prolong the standby time of the terminal product and the service life of the battery, we should reduce the power consumption of each circuit in the terminal product as much as possible. [0003] Taking a mobile terminal as an example, if the keyboard backlight of the mobile phone is turned on in a bright environment, the battery energy of the mobile phone will be consumed unnecessarily, the standby time of the mobile phone will be reduced, and the battery life will be shortened. Similarly, turning on the backlight of a Liquid Crystal D...
