Problems solved by technology

However, in actual use, even if the user is in a strong light environment, the keyboard light and the screen backlight are turned on, and the current is still consumed.
In order to avoid this part of the current consumption, many mobile phones set the option to turn off the keyboard light and screen backlight, but if you need to turn on the keyboard light when you bring it indoors or in a dark environment, you have to reset it, which is very inconvenient

Embodiment 1

[0042] image 3 It is the circuit diagram of the mobile phone terminal in this embodiment. As shown in the figure, a traditional mobile phone terminal mainly includes: a central processing unit, a radio frequency unit and a baseband circuit, wherein the radio frequency unit and the baseband circuit are connected to the central processing unit. In addition, traditional mobile phone terminals also include SIM cards connected to the central processing unit, storage devices (such as FALSH and RAM), SMS modules, lighting devices and LCD display screens, and lighting devices are further divided into screen lighting devices (such as screen backlights or LCD display lighting device) and key lighting device. On the basis of the traditional mobile phone terminal, the mobile phone terminal of this embodiment adds an illumination control device and a photosensitive sensor, both of which are respectively connected to the central processing unit. In practical applications, the lighting co...

Embodiment 2

[0052] This embodiment follows the method in embodiment 1 image 3 , Figure 4 and Figure 5 , the difference is: Figure 4 The storage unit in the lighting control device does not store the preset maximum value P max and minimum P min , but a range of multiple light intensities, assuming that these light intensity ranges are arranged from low to high: P min ~P 1 ,P 1 ~P 2 ,P 2 ~P 3 ,...,P n ~P max , and the lighting device of the mobile phone terminal in this embodiment can present different brightness levels B when it is turned on 0 , B 1 , B 2 ,...,B n , where: from B 0 to B n Decreases in order of brightness. The multiple stored light intensity ranges correspond to different brightness levels respectively. In this embodiment, the corresponding relationship is as follows: Figure 7a As shown in the table, it can be seen from the table that as the light intensity ranges from low intensity to high intensity, the corresponding brightness level decreases conti...

Embodiment 3

[0060] In Embodiment 1 and Embodiment 2, the photosensitive sensor must always detect the intensity of ambient light, therefore, the lighting control device also needs to perform processing and control all the time. However, in actual situations, the light intensity of the environment does not always change. In order to save processing overhead, this embodiment considers adding a new timer on the basis of the structure of the mobile phone terminal in Embodiment 1 and Embodiment 2. When the timer reaches the set time, the photosensitive sensor will be triggered to detect, and the working state of the lighting device will be adjusted through the lighting control device.

[0061] The mobile phone terminal circuit diagram of this embodiment continues to use image 3 , in the actual mobile phone terminal, the timer can be located in the photosensitive sensor, lighting control device or central processing unit, or be an independent entity. In this embodiment, the timer is no longer...

Abstract

The invention provides a means of illumination of a mobile communication terminal and the mobile communication terminal. The means of illumination comprises that the mobile communication terminal detects the environment light intensity through a photosensitive sensor; the mobile communication terminal controls the working status of an illuminating device of the mobile communication terminal through the environment light intensity detected. The invention controls the brightness of the screen and the keyboard of the mobile communication terminal via the photosensitive sensor so that the mobile communication terminal can automatically adjust the brightness of the screen and the keyboard backlight according to the light intensity of the application environment so as to reduce the current consumption of the mobile communication terminal, which greatly improves the time of standby and conversation under a stable battery capacity.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a lighting method for a mobile communication terminal and the mobile communication terminal. Background technique [0002] Mobile phones are an important tool for people to communicate, communicate and connect at present. In the process of using a mobile phone, people often expect a longer standby time and talk time. In addition to the fixed radio frequency signal during the call, the battery consumption of the mobile phone is also the main part of the battery consumption. If you can control this part of the consumption, you can achieve the purpose of increasing standby and talk time. However, in actual use, even if the user is in a strong light environment, the keyboard light and the screen backlight are turned on, and the current is still consumed. In order to avoid this part of the current consumption, many mobile phones have the option to turn off the keyboard l...
