Description

Liquid crystal display screen with self-cleaning function

Technical Field

The utility model relates to the technical field of liquid crystal display screens, in particular to a liquid crystal display screen with a self-cleaning function.

Background

Liquid crystal displays are used in digital watches and one type of display for many portable computers. Two pieces of poled material are shown in use, with a liquid crystal solution between them. When current is passed through the liquid, the crystals will rearrange so that light cannot pass through them. Thus, each crystal acts like a louver, both allowing light to pass through and blocking light. Liquid crystal displays are currently developed towards the goal of being light, thin, short, and small, and display products having a long history in the computer periphery are certainly no exception. Under the precondition of easy carrying and transportation, the conventional display methods such as CRT video display and LED display are all limited by the factors of too large volume or huge power consumption, which cannot meet the practical requirements of users. The development of the liquid crystal display technology is just in line with the trend of the current information products, and the user can enjoy the best visual environment no matter the advantages of right-angle display, low power consumption, small volume, zero radiation and the like.

At present, most of liquid crystal display screens for outdoor propaganda are not provided with cleaning mechanisms, and workers are required to clean the display screens at regular time, so that information can be well transmitted to viewers by the screens, but the screens can often adsorb a lot of dust impurities due to multiple outdoor weather changes under the condition of strong wind weather, and the workers cannot clean the screens in time.
