Abstract
An area light source display module is provided. The area light source display module includes a substrate and a light emitting diode (LED) array disposed on the substrate. A plurality of LED particles disposed on the LED array emit wide-angle light. Each of the LED particles has a lower light intensity distribution at a center of 0° and a higher light intensity distribution at an off-center polar angle θ. θ ranges between 30 degrees and 80 degrees. The LED array includes LED particles emitting the wide-angle light. Therefore, the area light source module can adopt fewer LEDs at a same thickness of the light source display module with an LED having a common light shape, or the area light source module can have a smaller light mixing distance with the same number of LEDs.
