LED backlight LCD TV

Abstract

The invention discloses a novel LED backlight liquid crystal television. The structure includes a protective frame and a liquid crystal screen. Back-shaped frame and power mechanism, compared with the prior art, the beneficial effect of the present invention is: no need to artificially cover the LED liquid crystal screen, based on the magnetic principle and the characteristics of the clockwork, when the LED liquid crystal screen is in the energized state, the electromagnet also In the power-on state, the protective curtain is rolled inward away from the LED screen. When the LED LCD screen is in the power-off state, the electromagnet is also in the power-off state, and the protective curtain covers the LED screen. When it is idle, it can effectively prevent the LED screen from being contaminated with dust and impurities, and avoid In the southerly weather, the screen has dust and dirt, so as to prevent the screen from being scratched by human beings, which has a good protective effect on the screen, so that the clarity of the screen will not be affected.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to an LED backlight liquid crystal television. Background technique [0002] Because the LED is very sensitive to the passage of current, it can emit light with a very small current, and it has a long lifespan and can flash for a long time without damage. Therefore, it is widely used in the indicator lights of electronic products. , which uses LED as the backlight, which has more advantages than the traditional LCD TV with CCFL backlight in thickness, picture quality, lifespan, energy saving and environmental protection, and can better meet people's needs. [0003] Existing LED LCD screens are fixed on the wall by screw connection. This installation method makes the LED screen exposed. In southerly weather, the weather is humid, so the surface of the LED screen is relatively humid and easily contaminated with dust and impurities. , when the south wind is over, the dust and impurities ...

AI Technical Summary

Problems solved by technology

[0003] Existing LED LCD screens are fixed on the wall by screw connection. This installation method makes the LED screen exposed. In southerly weather, the weather is humid, so the surface of the LED screen is relatively humid and easily contaminated with dust and impurities. , when the south wind is over, the dust and impurities are scaled on the LED screen, and it is difficult to clean up. It will be covered with a beautiful decorative cloth. This method needs to be covered artificially. The number of times of using the LED LCD screen is directly proportional to the number of times of artificial covering. If the artificial covering is frequent, it will be very troublesome, and the probability of forgetting to cover the LED LCD screen is still relatively high.
