Abstract

The invention discloses a display device, which includes a display panel, a backlight module and a rear light redirection layer. The display panel has a bottom surface. The backlight module is arranged on the bottom side of the display panel and has a light guide plate and a light source. The light guide plate has a first surface opposite to the bottom surface and a second surface parallel to the first surface. The light guide plate also has a light incident surface located on the side of the light guide plate, and the light source is arranged along the light incident surface. The rear light redirecting layer is disposed on the second surface near the edge and includes a first area and a second area. Part of the light entering the light guide plate will emerge from the second surface to the rear light redirecting layer, and will be refracted by the first area and the second area to produce different exit angles.

Description

technical field [0001] The present invention relates to a display device; specifically, the present invention relates to a display device with ambient light compensation. Background technique [0002] Flat and curved display devices have been widely used in various electronic devices, such as mobile phones, personal wearable devices, televisions, vehicle hosts, personal computers, digital cameras, handheld video games, and so on. However, in order to improve the user's visual experience, the industry is still constantly improving the optical performance of the display device. [0003] However, what is often overlooked by users is that when using a display device, it is necessary to pay attention to the matching of its brightness and external ambient light, so as to reduce damage to eyes caused by long-term use. Taking a personal computer screen as an example, if the screen brightness is high and the surrounding environment is too dark, the user's pupils will dilate and feel...
