Anti-glare device of digital television

Abstract

The invention discloses an anti-glare device for a digital TV, comprising a body, a display screen is arranged in the middle of the body, the display screen is embedded and arranged inside the body, and is connected with the body. Connected by screws, the top of the display screen is provided with light collectors, the sides of the light collectors are provided with rectangular slide rails, and the adjacent sides of the slide rails are provided with switch keys. The bottom is provided with a bracket, the bracket is arranged through the inside of the fuselage, and is fixedly connected with the fuselage by bolts. The outer side of the fuselage is provided with a USB port, and the USB port is nested and arranged in the fuselage. The interior of the fuselage is electrically connected to the fuselage. The anti-glare device for digital TV sets adds an XYC‑PTLQ580AC photosensitive sensor and a LHI778 infrared sensor, which can automatically adjust the light transmittance of the light adjustment screen. Improved intelligence.

Description

technical field [0001] The invention relates to the field of anti-glare technology, in particular to a digital TV anti-glare device. Background technique [0002] The so-called anti-glare refers to filter the strong light in the image, adjust the signal brightness of the video to the normal range, and avoid the large contrast between the front and back of the same image from affecting the viewing effect. Currently, only the display screen can be used to offset part of the strong Light, but the specific use effect is still limited. [0003] However, the existing anti-glare devices have low definition and insufficient viewing angles, which affect the visual effect. Some still have geometric distortion, poor contrast, short service life, high power consumption, and large power consumption, so they cannot be completely filtered out. Ultraviolet and infrared rays have large radiation, which greatly affects the user's health. Watching for a long time will easily reduce the user's...

[0003] However, the existing anti-glare devices have low definition and insufficient viewing angles, which affect the visual effect. Some still have geometric distortion, poor contrast, short service life, high power consumption, and large power consumption, so they cannot be completely filtered out. Ultraviolet and infrared rays have large radiation, which greatly affects the health of the user. Watching for a long time will easily reduce the user's vision and reduce the user's personal safety.
