Description

Technical Field

[0001] The utility model relates to the field of LED electronic displays, and particularly to a brightness enhancement and diffusion sheet for an LED TV screen. Background Technique

[0002] LED displays have a high brightness and can provide clear pictures under different lighting conditions. In addition, LED displays have a higher contrast ratio, making the images more vivid. Compared with traditional CRT displays and some LCD displays, LED displays are more energy-efficient and have lower power consumption, which helps save electricity bills and reduce environmental impact. LED displays are usually thinner and lighter in design, making them easy to install and move, suitable for various occasions such as homes and offices. LED displays usually have a longer service life. Compared with other types of displays, the brightness decay of LEDs is slower, and they can maintain high-quality display effects for a longer time. Many LED displays provide wide viewing angle technology, enabling better viewing angles without color deviation or brightness reduction. LED displays have a fast response time and are suitable for scenarios such as gaming and video playback that require fast picture updates. Compared with some other types of displays, LED displays usually do not contain harmful substances and are recyclable, meeting the requirements of modern environmental protection. Due to their high performance and energy efficiency, LED displays have become the mainstream choice for modern display devices.

[0003] When using an LED display, if it is close to a place with bright light such as a window, the phenomenon of not being able to clearly see the screen often occurs. The reason is that the environment is bright, and the pupils of the human eyes dilate relatively large, so it is not easy to clearly see a darker picture. The solution is also very simple, that is, to increase the brightness of the display. However, looking at a brighter and sharper light source for a long time, that is, the display, may damage the eyes. Content of the Utility Model
