WHITE POINT UNIFORMITY IN DISPLAY DEVICES

摘要

Embodiments of a device and a method of tuning white point values of light distributed by a backlight unit (101) of a display device (200) are described. The device includes a backlight unit (101), an image generating unit (106), and a patterned layer (240). The backlight unit (101) includes a light source unit (102) and an optical processing unit (104) having a quantum dot film (114) coupled to the light source unit (102). The image generating unit (106) includes a display screen (126). The backlight unit (101) is configured to distribute light to the display screen (126) and the patterned layer (240) is configured to tune white point values of the distributed light to a desired white point value in order to achieve substantially uniform white point values across the display screen.
