best displays for digital signage

As the COVID-19 epidemic breaks out all over the world, all walks of life are suffering from the impact of the epidemic, and the LCD industry has also suffered a cold winter, and demand has fallen sharply. The epidemic is a new test for the entire LCD panel industry chain. In previous years, at the China Import and Export Fair, twice a year, you could see people from all over the country going to Guangzhou to participate in the exhibition. But this spring, compared to face-to-face cooperation negotiations in the exhibition hall, all advertisers and LCD purchasers had to find another way to negotiate this year’s market cooperation projects. All LCD companies in Shenzhen have a problem in survival in such a big environment. It is understood that due to the impact of the epidemic, sales staff of many companies keep product prices low in order to place orders, but do not consider whether the quality of product accessories is satisfactory, which added many unnecessary after-sales problems to buyers. In other words, while pursuing low prices, we also need to pay for the quality problems caused by low prices. We hope everyone chooses carefully.

Liquid crystal display (LCD) is a kind of display using liquid crystal as material.   What is liquid crystal? In fact, liquid crystal is a kind of material between solid and liquid. When heated, it will appear transparent liquid, and when cooled, it will crystallize into chaotic solid. Liquid crystal is an organic compound with regular molecular arrangement.   According to the different arrangement of molecular structure, liquid crystals can be divided into three types: Smectic liquid crystals similar to clay, Nematic liquid crystals similar to thin matchstick and Cholesteric liquid crystals similar to cholesterol.   The physical properties of these three kinds of liquid crystals are not the same. Nematic liquid crystals of the second kind are used in liquid crystal displays. The molecules are long rods. In the natural state, the long axes of these long rods are roughly parallel.
