Embodiment Construction

[0038]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] An embodiment of the present invention provides a display device, such as figure 1 As shown, a display panel 1 is included.

[0040] Wherein, the display panel 1 has a display area (active area, AA area for short) and a peripheral area S, and the peripheral area S is set around the AA area, for example. A plurality of pixels 11 are arranged in the above-mentioned AA area.

[0041] On this basis, as figure 1 As shown, the display panel 1 includes a plu...

Abstract

The embodiment of the invention provides a display device and a light compensation method thereof, relates to the technical field of display, and can solve the problem that the brightness of the display device is low when ambient light is weak. The display device comprises a display panel, a backlight module and a light control layer located between the display panel and the backlight module, wherein the display panel comprises a plurality of display blocks, and each display block comprises at least one pixel; the light control layer comprises a plurality of light control units which are in alight transmission state under the control of a first signal and in a light reflection state under the control of a second signal and are in one-to-one correspondence with the display blocks in the thickness direction of the display panel; at least one detection element is arranged between each display block and the light control unit corresponding to the display block and used for detecting the intensity of ambient light entering the corresponding display block; a processor is electrically connected with the light control unit and the detection element, compares the light intensity detected by the detection element corresponding to the display block with a preset value, sends a first signal to the light control unit corresponding to the display block when the light intensity is less thanthe preset value, and sends a second signal when the light intensity is greater than or equal to the preset value.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device and a light compensation method thereof. Background technique [0002] A reflective display device mainly uses ambient light as a light source to reflect the ambient light incident into the display device to achieve a display effect, and generally does not require a backlight module to provide a light source, which is a relatively energy-saving display method. [0003] However, since the intensity of ambient light is easily affected by various factors, such as sunny or cloudy, outdoors or indoors, day or night, etc., the intensity of ambient light varies, resulting in the display brightness of reflective display devices also varying. change. Moreover, in the case of weak ambient light, reflective display devices have relatively low reflectance to light, and their display brightness is relatively weakened, thereby reducing the display effect of the display devic...
