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 of a display device are described. The device includes a backlight unit, an image generating unit, and a patterned layer. The backlight unit includes a light source unit and an optical processing unit having a quantum dot film coupled to the light source unit. The image generating unit includes a display screen. The backlight unit is configured to distribute light to the display screen and the patterned layer 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.

1. A device comprising:
a backlight unit comprising:
a light source unit; andan optical processing unit comprising a quantum dot film coupled to the light source unit; an image generating unit comprising a display screen coupled to the backlight unit, wherein the backlight unit is configured to distribute light across the display screen; and a patterned layer configured to tune white point values of the distributed light at different locations on the display screen to a desired white point value in order to achieve substantially more uniform white point values across the display screen.
