[0026] 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:

[0027] Step 101, collecting the luminance value of the light-emitting element;

[0028] 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...

[0036] 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:

[0037] Step 201, collecting the luminance value of the light-emitting element;

[0038] 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.

[0039] Step 202, according to the brightness value, determine the initial operating current corresponding to the brightness value;

[0040] 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 ...

[0058] 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 of the touch key (ie, touch key) of the mobile phone.

[0059] In this embodiment, the photoelectric conversion film is pasted on the touch key area of ​​the mobile phone, which is a kind of photoelectric sensor. The embodiment of the present invention can test the brightness signals of the left and right touch keys through the photoelectric conversion film, and automatically turn the left and right touch keys (including the key lights) ) brightness signal into an electrical signal, wherein there is a corresponding functional relationship between the optical signal and the electrical signal.

[0060] Moreover, in this embodiment, the photoelectric conversion film is connected to the mobile phone through a data line, and the mobile phone can obtain th...

Abstract

Embodiments of the invention provide a luminance adjustment method and a mobile terminal. The luminance adjustment method comprises the steps of collecting an optical luminance value of a light emitting element; determining an initial working current corresponding to the optical luminance value according to the optical luminance value; enabling the initial working current to be compared with a preset parameter value, and determining an adjustment working current which is to be input to the light emitting element; and adjusting the optical luminance value of the light emitting element according to the adjustment working current. According to the embodiments of the luminance adjustment method and the mobile terminal, the initial working current of the light emitting element can be determined by collecting the optical luminance value of the light emitting element; the adjustment current can be determined by comparison between the current and the preset parameter so as to adjust the optical luminance value of the light emitting element. Automatic adjustment on the working current of the light emitting element is realized; luminance uniformity of the lamplight, seen by eyes of a user, of the light emitting element is ensured; and in addition, the lamplight luminance of each light emitting element is consistent; therefore, manual assembling on a light conducting film is avoided; and in addition, the light emitting luminance values of the light emitting elements can be accurately and rapidly adjusted to be consistent, so that user experience is quite good.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method for adjusting brightness and a mobile terminal. 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...
