Problems solved by technology

[0002] With the enhancement of multimedia functions of handheld devices (such as PDAs and mobile phones, etc.), people have begun to use them to read e-books and watch movies, etc., and people are enjoying the convenience brought by it almost anytime and anywhere. The problem is: because the brightness of the external environment is constantly changing, the display effect of the liquid crystal display (LCD) will be different under different external environments. It is easy to cause eye fatigue, and there is also such a problem with the brightness adjustment of the keyboard backlight
[0003] The traditional method in the industry is to provide an interface for users to manually adjust the brightness and contrast of the LCD backlight. The control method is cumbersome and lacks user-friendliness. Moreover, when the adjustment is inappropriate, not only can not get good results, but it will waste the handheld device power

Description

technical field [0001] The invention relates to the field of handheld devices, in particular to the field of controlling the display effect of the backlight on the interface of the handheld device, in particular to a device and method for automatically adjusting the brightness and effect of the backlight of the handheld device. Background technique [0002] With the enhancement of multimedia functions of handheld devices (such as PDAs and mobile phones, etc.), people have begun to use them to read e-books and watch movies, etc., and people are enjoying the convenience brought by it almost anytime and anywhere. The problem is: because the brightness of the external environment is constantly changing, the display effect of the liquid crystal display (LCD) will be different under different external environments. It is easy to cause eye fatigue, and at the same time, there is such a problem in adjusting the brightness of the backlight of the operating keyboard. [0003] The tra...
