摘要

An electronic device and a display device are provided. The electronic device includes the display device and an object to be shown. The display device includes a display panel, a first backlight module, and a second backlight module. The display panel has a transparent area corresponding to the object. The first backlight module is disposed with a gap to the display panel and generates first backlight to reach the display panel. The second backlight module has a prism sheet and a collimated illumination. The prism sheet is parallel to the display panel and corresponding to the transparent area, while the collimated illumination generates light reaching the prism sheet. The light is orientated by the prism sheet and becomes a second backlight before entering the transparent area.

主权项

1. A display device, comprising:
a light modulation panel having a backside and a transparent area; a first backlight module disposed corresponding to the backside with a gap, the first backlight module generating a first backlight entering into the light modulation panel from the backside; and a second backlight module, comprising:
a prism sheet disposed parallel to the backside and corresponding to the transparent area; anda collimated backlight source disposed between the light modulation panel and the first backlight module, and two ends of the collimated backlight source respectively extend toward the prism sheet and the first backlight module; wherein the collimated backlight source generates light emitting at an incline to the prism sheet, and the prism sheet deflects the light to form a second backlight entering the transparent area.
