Title: LIGHT CONVERSION FILM FOR USE IN BACKLIGHT MODULE, BACKLIGHT MODULE, AND DISPLAY DEVICE
Abstract:
A light conversion film (102, 202, and 40) for use in a backlight module (502), the backlight module (501), and a display device. The backlight module (501) comprises a light source (101 and 201) for emitting at least a first type light; and the light conversion film (102, 202, and 40), the light conversion film (102, 202, and 40) receiving the first type light and converting same into at least a second type light for emission, thus allowing the light emission angle of the backlight module (501) to be greater than 120 and the color temperature to be less than 15000. This increases the viewing angle of the display device and allows a brightness viewing angle of 120 degrees or more; at the same time, the light conversion film (102, 202, and 40) provides increased light excitation efficiency, is capable of reducing the color temperature of the backlight module (501), and further enhances display effects.
