When customers use LCD, what should they pay attention to?

The following are the precautions for LCD module operation:   If the display screen is damaged and the internal LCD leaks, do not let it enter the mouth. If it gets on clothes or skin, wash it quickly with soap and water. In order to reduce static electricity, do not carry out assembly and other work in dry environment. The LCD module has a film to protect the display screen. Be careful when removing this protective film as it may generate static electricity. The display screen is made of glass. Do not apply mechanical impact, such as falling from height. It must be grounded correctly. Minimize electrode corrosion. Water droplets, moisture condensation or current in high temperature environment may accelerate electrode corrosion. At low temperature, liquid crystal solidification will lead to directional defects or bubbles. When the liquid crystal module is subject to strong vibration at low temperature, bubbles will also be generated. If the LCD module works for a long time and displays the same pattern, the pattern will remain on the screen like a phantom, and there will be subtle contrast differences. If you want to regain the normal working state, you can temporarily stop using it for a while. It is worth noting that this phenomenon will not have an adverse effect on the reliability of the performance.

Which is more advantageous, resistive touch screen or capacitive touch screen?

Capacitive touch screen and resistive touch screen are mainly different in touch sensitivity, precision, cost, multi touch feasibility, anti-damage, cleaning and visual effect in sunlight.   Touch Sensitivity Resistive touch screen: it needs pressure to make all layers of the screen contact. It can be operated with fingers (even with gloves), nails, stylus, etc. Support for stylus is very important in Asian market, gesture and character recognition are valued everywhere. Capacitive touch screen: the slightest touch from the surface of a charged finger can also activate the capacitive sensing system below the screen. Non-living objects, nails and gloves are invalid. Handwriting recognition is difficult.   Accuracy Resistive touch screen: the accuracy is at least a single display pixel, which can be seen when using the stylus. It is easy to recognize handwriting and is helpful to operate in the interface using small control elements. Capacitive touch screen: the theoretical accuracy can reach several pixels, but it is actually limited by the finger contact area. So that it is difficult for users to accurately click the target less than 1cm2.   Cost Resistive touch screen: very cheap. Capacitive touch screen: the price of capacitive screen from different manufacturers is 10% to 50% higher than that of resistive screen. This extra cost doesn’t matter for flagship products, but it may deter mid-priced phones.   The feasibility of multi touch Resistive touch screen: not possible unless the resistive screen is reconstituted and connected to the circuit of the machine. Capacitive touch screen: depending

Market development of LCD splicing screen

In recent years, there have been more and more LCD splicing screen manufacturers, and competition in the large-screen splicing market has gradually become fierce. With the continuous breakthroughs in the three mainstream splicing product technologies such as LCD LCD splicing, DLP rear projection splicing, and PDP plasma splicing, LCD splicing There are more and more types of screens, and more and more diversified sizes, and there are more options for users to choose from. However, LCD splicing screens also have two sides, so the current large-screen splicing market is facing a complex situation such as a large number of convergent products and chaotic price wars. Especially with the rapid development and wide application of the LCD splicing industry, some people in the industry have suggested that the large-screen splicing industry may face a reshuffle. So where is the future of large-screen splicing? From the overall splicing market, analyze the technical aspects and industry applications of the three large-screen products, LCD LCD splicing screen, DLP rear projection splicing screen, and PDP plasma splicing screen. LCD splicing screens are the first choice. Since Samsung launched 46-inch ultra-narrow-edge splicing products in 2009, the LCD splicing market has shown a sustained high growth trend. The large LCD splicing screen has the advantages of high definition, high brightness, high color saturation, flexible splicing display combination, environmental protection and health, long life span, and low maintenance cost. At present, the largest LCD splicing unit on the market can be as large as 65 inches, and is
