Title: OPTICAL FILM FOR USE WITH BACKLIGHT MODULE, BACKLIGHT MODULE AND DISPLAY DEVICE
Abstract:
An optical film (102) for use with a backlight module, a backlight module and a display device. The backlight module comprises: a light source (101), which emits at least a first type of light ray; an optical film (102), which comprises a light converting material, the light converting material receiving the first type of light ray and converting the same into at least a second type of light ray such that the light emission angle of the backlight module is greater than 120 degrees. The present invention may cause the light emission angle of the backlight module to be greater than 120 degrees, thereby enabling the display device to attain a wide viewing angle effect.
