Problems solved by technology

However, because the ambient light sensor of the existing solution must be designed in an area outside the screen display area, the existing technology affects the screen-to-body ratio of the whole machine, which is not conducive to ID design.

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] A method for detecting ambient light intensity, which is applied to electronic equipment. The electronic equipment includes a display screen and an ambient light sensor arranged at the lower end of the display screen. A collimating mirror is added between the display screen and the ambient light sensor. The collimating mirror can make the display The light outside the screen can better enter the ambient light sensor, and at the same time, it can also reduce the interference of the screen light on the ambient light. The ambient light intensity detection method includes the following steps:

[0026] (1) When the ambient brightness is 0 Lux, obtain the light intensity information received by the ambient light sensor during the process of increasing the display screen from the lowest brightness to the highest brightness, and obtain the basic data;

Abstract

The invention discloses an environment light intensity detection method applied to an electronic device. The electronic device comprises a display screen and an environment light sensor arranged at alower end of the display screen, wherein a collimating mirror is further added between the display screen and the environment light sensor, and the environment light intensity detection method comprises the following steps: when environment brightness is 0Lux, performing basic data acquisition, binding a brightness range of environment light with a light intensity information range from the lowestbrightness to the highest brightness of the display screen, and according to the basic data and calibration data, acquiring external environment light intensity information under a screen turned-offstate and a screen turned-on state and outputting corresponding light intensity information by the electronic device. With the environment light intensity detection method, the environment light intensity can be acquired accurately, the environment light brightness can be acquired accurately, the brightness output of the display screen becomes more precise, the environment light sensor is helped to be arranged at the lower end of the display screen without occupying an effective display region of the display screen, and full screen design is facilitated more.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a method for detecting ambient light intensity. Background technique [0002] Display screens are widely used in various electronic devices, such as mobile phones, applause computers, etc. Especially for mobile phones, the development of display screens tends to be more full-screen design. The space is getting smaller and smaller, but there are too many components that need to be integrated on the front of the mobile phone: earpiece, RGB camera, infrared camera, infrared dot matrix projector, breathing light, light sensor, distance sensor, color temperature sensor, etc. Therefore, it is more and more difficult to design the top of the mobile phone to be narrower. It is necessary to design the above-mentioned components under the display area to reduce the space outside the display screen and achieve a higher screen-to-body ratio, making it more difficult to achieve ...
