Background lighting device of information terminal

Abstract

The embodiment of the invention relates to a background lighting device of an information terminal. The background lighting device comprises an illuminating lamp, a driving module for controlling theilluminating lamp and a first port for connecting the information terminal. The background lighting device further comprises a control module, which is arranged on the information terminal or in the background lighting device. The control module installed on the information terminal is connected with the first port through a second port of the information terminal, and controls the illuminating state of the illuminating lamp. The control module arranged in the background lighting device is connected with the driving module and controls the lighting state of the illuminating lamp, and is connected with the second port of the information terminal through the first port. The control module receives the control data input by a user according to the display parameters of the display screen of the information terminal and sends the control data to the driving module, so that the illuminating parameters of the illuminating lamp can be adjusted so as to control the illuminating output of the illuminating lamp.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to a background lighting device for an information terminal. Background technique [0002] Today, with the development of Internet electronic products such as mobile phones and tablets, more and more people stare at video terminals such as mobile phones for a long time, causing visual fatigue of human eyes, which leads to vision loss and affects visual health. [0003] At present, most smartphones come with an automatic brightness adjustment mode. The brightness sensor located near the earpiece recognizes the surrounding light environment to detect the brightness of the surrounding environment, and then calculates the brightness of the screen display according to a preset algorithm. [0004] However, users often encounter the situation that the display of screen brightness under this automatic adjustment method does not conform to their own visual perception, especially for scenes...

AI Technical Summary

Problems solved by technology

[0004] However, users often encounter the situation that the display of screen brightness under this automatic adjustment method does not conform to their own visual perception, especially for scenes with relatively dark ambient brightness, even if the brightness of the display screen is adjusted. Adjustment, it is still unable to fully adapt to the brightness of the surrounding environment and at the same time take into account the normal visualization needs of users

At present, there is no good way to solve the above problems in the industry.
