How to do regular maintenance of large-screen optical equipment, DLP seamless splicing screen wall maintenance guide, as long as you remember and follow it, DLP seamless splicing screen wall will be no problem for 50 years. 1. Put the large-screen optical equipment in an environment that is easy to ventilate to increase the service life of the bulb of the large-screen optical equipment. 2. Regular cleaning of large-screen optical equipment can improve the brightness and contrast of the large-screen display system (increased by 10% to 30%). 3. When the temperature is very low, it will affect the normal use of the outdoor large screen. Generally, it is recommended to temporarily stop using it when it is below minus 30 degrees Celsius. Of course, taking other measures, such as installing an air conditioner in the box, can also ensure normal use. 4. Pay attention to the maintenance of daily optical components (color wheel, LCD panel, polarizer, lens, etc.) to prevent premature aging. 5. If the DLP seamless splicing wall fails, please contact the manufacturer in time. The above five points are the maintenance guide for DLP seamless splicing screen wall for everyone. I hope you will pay more attention to it during use.

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.

We will use some electronic devices in our life, LCD module is one of the electronic components. Everyone’s understanding of it must be relatively strange, and then we will talk about the knowledge in this respect.   The following is an introduction to the three basic components and features of LCD. Let’s take a look with the editor: Liquid Crystal Materials Liquid crystal material is the main body of liquid crystal display. Different devices use different liquid crystal materials. Most liquid crystal materials are composed of several or even more than ten kinds of single liquid crystal materials.   Polarizer The light sheet, also known as polarized light, is made of plastic film material, coated with a layer of optical pressure sensitive adhesive, which can be pasted on the surface of the liquid crystal cell. There is a protective film on the surface of the front polarizer, which should be removed when using. The polarizer is afraid of high temperature and high humidity, which will depolarize or blister under high temperature or high humidity conditions.   Glass Substrate A kind of float production thin glass sheet with extremely flat surface, the surface of which is evaporated with a layer of zn203 or sn02 transparent conductive layer, i.e. ITO film, is processed into transparent conductive pattern. If scratched, cut or corroded, the vacuum device will be scrapped.
