Embodiment Construction

[0036] Next, specific examples of the display device and the method for controlling the brightness of the display device according to the embodiments of the present invention will be described by way of example with reference to the accompanying drawings. The drawings are schematic, not drawn to scale, and are intended only to illustrate embodiments of the invention and are not intended to limit the scope of protection of the invention.

[0037] It will be understood that when an element or layer is referred to as being "on," "over," "over," "connected to," or "coupled to" another element or layer, it can be directly on, Connected or coupled to another element or layer, or intervening elements or layers may also be present. In contrast, when an element is referred to as being "directly on," "directly connected to" or "directly coupled to" another element or layer, there are no intervening elements or layers present.

[0038] As mentioned above, the existing methods for contro...

Abstract

Embodiments of the present invention provide a display device and a method for controlling brightness of the display device. The display device may include: a first substrate and a second substrate oppositely arranged; a reflector disposed on a side of the first substrate opposite to the second substrate; a light intensity detector disposed on the second substrate opposite to the first substrate On the opposite side, a light intensity detector configured to sense the light intensity of light reflected by the reflector inside the display device; and a controller electrically connected to the light intensity detector, configured to sense A comparison of the measured light intensity with a predefined light intensity range controls the brightness of the display device. Through the display device and the method for controlling the brightness of the display device according to the embodiments of the present invention, the brightness of the display device can be better controlled so as to improve the display quality.

Description

technical field [0001] The invention relates to display technology, in particular to a display device and a method for controlling the brightness of the display device. Background technique [0002] With the rapid development of electronic devices such as smart phones and tablet computers, people have higher and higher requirements on the display quality of display devices. In order to improve the display quality, it is usually necessary to control the brightness of the display device so that the picture is displayed with an appropriate brightness. [0003] Existing methods for controlling the brightness of a display device include separately manufacturing an additional sensing unit, sensing ambient light, and the like. However, these methods are not accurate enough for sensing the light intensity and the process is complicated, which increases the cost of manufacturing the display device. Contents of the invention [0004] Accordingly, it is desirable to provide an impr...
