    Abstract: Embodiments of a device and a method of forming the same are described. The device includes a backlight unit and an image generating unit. The backlight unit includes an optical cavity having a top side, a bottom side, and side walls. The backlight unit further includes an array of light sources coupled to the optical cavity and a quantum dot film positioned within the optical cavity. The quantum dot film is configured to process light received from the array of light sources and the backlight unit is configured to transit the processed light to the image generating unit. The method includes providing an optical cavity having a top side, a bottom side, and side walls. The method further includes coupling an array of light sources to the optical cavity and supporting a quantum dot film within the optical cavity.

    Abstract: 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.

    Abstract: Embodiments of a display device and a method of reducing optical leakage from a backlight unit of a display device are described. The display device includes a backlight unit, an image generating unit coupled to the backlight unit and a blocking structure. The backlight unit is configured to transit light to the image generating unit and the blocking structure is configured to prevent the light from reaching the image generating unit without passing through the optical processing unit. 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 method of reducing optical leakage from the backlight unit of the display device includes providing a first blocking structure to a portion of the light source unit and providing a second blocking structure to a portion of the optical processing unit.
