Abstract: 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.

Abstract: Embodiments of a display device (300) and a method of reducing optical leakage from a backlight unit (202) of a display device (300) are described. The display device (300) includes a backlight unit (202, 208, 204), an image generating unit (206) coupled to the backlight unit and a blocking structure (334a-334e). The backlight unit (202, 208, 204) includes a light source unit (202) such as a blue LED and an optical processing unit (204) that comprises a quantum dot film (214) and optical sheets (222, 216). The backlight unit (202, 208, 204) is configured to transmit light to the image generating unit (206); the blocking structure (334a-334e) is configured to prevent the light from reaching the image generating unit without passing through the optical processing unit. The blocking structure (334a-334e) may consist of light-shielding tape, tabs or paint arranged along the periphery of the light guide plate (212), the optical sheets (22, 216) and the quantum dot film (214).
