[0023] refer to figure 1 , which shows a flow chart of a brightness adjustment method according to an embodiment of the present invention, which is applied to a mobile terminal including at least one light-emitting element, and the method may specifically include the following steps:

[0024] Step 101, collecting the luminance value of the light-emitting element;

[0025] Among them, light-emitting elements such as touch keys are installed on mobile terminals (such as mobile phones), but the brightness emitted by some light-emitting elements is not uniform, or, for some light-emitting elements arranged symmetrically or in groups, their power supply The current is the same, the purpose is to make the brightness of the lights they emit consistent, and because the light guide film on the upper surface of these light-emitting elements is easily misplaced with the corresponding light-emitting elements when attached, resulting in the light-emitting elements with the same supply curr...

[0033] refer to figure 2 , which shows a flow chart of a brightness adjustment method according to another embodiment of the present invention, which is applied to a mobile terminal including at least one light emitting element, and the method may specifically include the following steps:

[0034] Step 201, collecting the luminance value of the light-emitting element;

[0035] Wherein, the light-emitting element here may include: at least one of a light element below the touch key, a light element below the key, and a breathing light, and the light element may be an LED light.

[0036] Step 202, according to the brightness value, determine the initial operating current corresponding to the brightness value;

[0037] Wherein, before step 202 is performed, the embodiment of the present invention pre-stores the corresponding relationship between the luminance value and the initial operating current. Therefore, the initial operating current corresponding to the luminance value ...

[0055] In order to better understand the above-mentioned embodiments of the present invention, the above-mentioned technical solution of the present invention will be described in detail below with a solution of adjusting the light brightness of the touch key (ie, touch key) of the mobile phone.

[0056] In this embodiment, an optical luminance meter is connected to the touch key area of ​​the mobile phone. In the embodiment of the present invention, the luminance values ​​(ie, luminance values) of the left and right touch keys can be tested by the optical luminance meter.

[0057] Moreover, in this embodiment, the optical luminance meter is connected to the mobile phone through a data cable, and the mobile phone can obtain the luminance value transmitted by the optical luminance meter. For example, the brightness value of the left touch key is 0.07cd / m2, and the brightness value of the right touch key is 0.21cd / m2.

[0058] Among them, the power supply current value of the ge...

Abstract

The embodiment of the invention provides a brightness adjusting system. The system comprises a mobile terminal comprising at least one light-emitting element, and an induction device connected with at least one light-emitting element of the mobile terminal, wherein the induction device is used for acquiring a light brightness value of the at least one light-emitting element; the mobile terminal further comprises a first determination module for determining the initial working current corresponding to the light brightness value according to the light brightness value; a second determination module for comparing the initial working current with a preset parameter value to determine an adjusting working current to be input to the light-emitting element; and an adjusting module for adjusting the light brightness value of the light-emitting element according to the adjusting working current. The system disclosed by the embodiment of the invention can determine the initial working current of the light-emitting element and the adjusting working current according to the light brightness value of the light-emitting element acquired by the induction device, thereby adjusting the light brightness value of the light-emitting element. The light-emitting brightness value of the light-emitting element can be accurately and fast adjusted as consistency, and the user experience is strong.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a brightness adjustment system. Background technique [0002] Most of the screens of current mobile terminals are equipped with light-emitting elements such as touch buttons and breathing lamps. In order to facilitate users to use the touch buttons and / or breathing lights of mobile terminals normally in a weak light environment, it is necessary A light guide film is attached to the button light or breathing light to facilitate users to use the mobile terminal in a dark environment. However, due to factors such as the differences in the LED lights that make up the button lights or breathing lights, the large assembly misalignment between the LED lights and the light guide film, and the processing errors in the silk screen printing of touch screen characters, the light brightness of mobile terminal devices Unevenness, and there is a large difference in the brightness of the ...
