Technical Field

[0002] In the modern home entertainment environment, television is an indispensable device. However, when the TV is in use, it is often interfered with by the surrounding light and causes glare problems. Whether it is the reflection of indoor lights or the outside sunlight shining through the window onto the TV screen, these lights are reflected by the screen and enter the human eye, which will reduce the contrast and clarity of the screen image, making it difficult to distinguish the details of the picture, seriously affecting the viewing experience.

[0003] Traditional TV screens mainly use single technical means such as frosting or anti-reflective coating to prevent glare. Although frosted screens can scatter light to a certain extent and reduce mirror reflections, they will reduce screen clarity and make the image blurred. Ordinary anti-reflective coatings have limited anti-glare effects in complex lighting environments and cannot meet the needs of light exposure at different angles and intensities.

[0004] To this end, we provide an anti-glare television optical lens group structure to solve the above problems. Utility Model Content
