Nowadays, LCD TVs have led the entire TV industry and have entered the entire family. Along with this, many LCD TVs often cause a sharp drop in the use cycle due to the inadvertent and unmaintained details in the usual use, and are prone to cause a lot of small problems. In this issue, we will introduce a few common tips on the maintenance of LCD TVs to help you extend the life of LCD TVs.
First, don't turn off the TV without letting everyone waste power. Instead, pay attention to the trade-offs that affect the life of the TV. Backlighting is one of the most demanding components of LCD TVs. It is very similar to the fluorescent tubes used in our homes. The service life and the number of ignitions also have a lot to do with it. Pre-heating and sputtering of high-voltage pulsed cathode electrons at startup will shorten the life of the backlight. If you develop the habit of turning off the TV, the life of the backlight will be reduced to 1/2 of the original four times a day.
Second, avoid working long hours. This article does not conflict with the above considerations. In the case of working for a long time, heat will accumulate inside the fuselage of the LCD TV, which is not enough to threaten other electronic components, but the LCD panel may burn out, thus forming a large area of ​​dead pixels. .
Third, you should avoid powering when cleaning the screen. Wiping itself is a very unwise way to clean. Not only the cleaning effect is general, but also easy to leave water marks. It is important that the liquid crystal is very easy to cause permanent damage due to moisture (if the water droplets penetrate the screen, let the water evaporate slowly in a warm environment).
Fourth, avoid scratching, twisting or hitting the surface of the LCD screen. The habit of pointing fingers to the screen may cause fatal damage to the LCD TV. At the same time, it is necessary to look after your child and their toys. Any impact or slash on the LCD screen will cause direct damage and is very likely. Make the entire screen scrapped.

Solid-phase synthesis, as the main process in the production of Bio-pharmaceuticals, is widely used for the synthesis of peptides, deoxyribonucleic acid (DNA) and so on. The synthesis method is to bound the functional group such as hydroxymethyl on a bead, which primiarly is polystyrene microsphere with low crosslink.
Solid Phase Synthesis Resin based on monodisperse beads is able to keep the unformity of the modified functional group, enhance the quality of the target products, reduce the occurance of drug allergy and lower the production cost.
