  • Optical lens, backlight module and display device using same
    Patent number: 10890802
    Abstract: A backlight module capable of simple manufacture and a display device using the backlight module are provided. A reflective sheet to redirect the light from LEDs or other light source is located in position on the backlight module by means of optical lenses, which also spread the light for better uniformity of lighting. The optical lens includes inclined surfaces which form an opening with a circuit board that allows engagement of a reflective sheet. The reflective sheet is between the optical lens and the circuit board. The manufacturing step of fixing the reflective sheet to the circuit board is not required, and when any LED or other light emitting element, or the circuit board itself, fails, it is only necessary to disassemble the optical lens at the one position. Assembly and maintenance efficiency are improved, and the reliability of the backlight module and the display device is improved.
