Display device and control method thereof

Abstract

The embodiment of the invention provides a display device and a control method thereof. The display device comprises at least two display modules, at least one dimming part, a line-of-sight tracking part and a brightness sensor; each dimming part is arranged on the spicing place of every adjacent display modules; the line-of-sight tracking part is electrically connected with the dimming parts andused for tracking the line of sight of human eyes and adjusting the angle of light emitted from the splicing places according to the line of sight to make light energy obtained by the splicing placeswithin a line-of-sight range during distribution; the brightness sensor is electrically connected with the dimming parts and used for sensing and measuring the brightness of the external environment,and the dimming parts adjust the brightness of the light emitted from the splicing places according to the brightness of the external environment and the preset display brightness of the display device to make the splicing places obtain the light energy equal to the brightness of the external environment during the distribution. By arranging the dimming parts to adjust the emitting angle and brightness of the light of the splicing places, the splicing places obtain the light energy equal to the brightness of the external environment during the distribution so that the splicing places can display images visually, and therefore the non-bezel or narrow-bezel effect of the display device is achieved.

Description

technical field [0001] Embodiments of the present invention belong to the technical field of liquid crystal display, and in particular relate to a display device and a control method thereof. Background technique [0002] With the continuous development of science and technology, various liquid crystal display devices such as LCD TVs and liquid crystal displays are becoming more and more popular, and are widely used in various places where information needs to be displayed, such as residences, shopping malls, and office buildings, bringing great benefits to people's production and life. convenient. [0003] However, most of the existing liquid crystal display devices have relatively wide borders, especially in large public places such as shopping malls and office buildings, where large liquid crystal display devices are formed by splicing multiple small liquid crystal display devices. The frame area usually cannot transmit light and cannot display the picture, which serious...

[0003] However, most of the existing liquid crystal display devices have relatively wide frames, especially for large-scale liquid crystal display devices that are spliced ​​by multiple small liquid crystal display devices in large public places such as shopping malls and office buildings. The frame area usually cannot transmit light and cannot display the picture, which seriously affects the display effect and reduces the visual experience
