Description

Technical Field

[0001] The utility model relates to the technical field of automatic control, in particular to a mobile phone glass backlight panel which can automatically turn on and off. Background Art

[0002] The backlight is a light source device used to ensure that the back of the LCD screen emits bright light. The backlight is a very important part inside the mobile phone, which can ensure that people can see the mobile phone screen clearly. Most backlights are made of LED material, so they are more energy-efficient.

[0003] Since the image on the mobile phone glass cannot be seen clearly without backlight, a backlight panel is needed to illuminate the mobile phone glass when testing whether the image on the mobile phone glass is normal. The current mobile phone glass backlight panel relies on manual control of the dial switch to control the on and off of the backlight;

[0004] The biggest problem with the mobile phone glass backlight panels currently on the market is that once the mobile phone glass is removed, strong light will directly shine on the human eye, which is harmful to the human eye. It is inconvenient to manually turn on and off the switch when doing a large number of tests, and the switch needs to be used manually, which is not convenient for automatically determining the light-on and light-off status according to whether there is a mobile phone glass on the backlight panel. For this reason, a mobile phone glass backlight panel with automatic light-on and light-off is proposed. Utility Model Content
