Abstract

A display and a brightness adjusting method thereof are provided. In the method, an object located in front of a touch screen of the display is detected and a distance between the object and the touch screen is estimated and determined whether to be less than a first preset value. When the distance is less than the first preset value, the brightness of the touch screen is adjusted according to a light adjusting ratio in a brightness distribution curve. Then, time is accumulated after the brightness adjustment and when the accumulated time is over a second preset value, the brightness of the touch screen is resumed to original brightness.

Description

technical field [0001] The present invention relates to a display and its brightness adjustment method, and in particular to a display and its method for adjusting the brightness by detecting the distance of objects. Background technique [0002] With the advancement of display technology, today's liquid crystal displays have the advantages of low power consumption, thin and light weight, high resolution, high color saturation, and long life, so they replace traditional cathode ray tube (CRT) displays and are widely used in Various electronic products with display functions. In daily life, LCDs can be used in computer screens, TVs, mobile phones, cameras and other electronic devices; in teaching, LCDs can be used in electronic whiteboards. [0003] The electronic whiteboard provides teachers with a convenient writing and teaching tool. It is equipped with a touch screen, which can detect the touch of the stylus held by the teacher, and can draw on the touch screen according...
