Advantages of ultra-narrow LCD splicing screen

The ultra-narrow LCD splicing screen is based on pure hardware and adopts parallel high-speed graphics processing technology to realize the unified processing of multiple high-speed video signals, fundamentally replace the plug-in splicing controller, and solve the problem of limited VGA signal input. Clarity, brightness, and color saturation are three important performance indicators of liquid crystals. The ultra-narrow-edge LCD splicing unit has the characteristics of high definition, high brightness, and high color gamut. Because the LCD uses backlight tubes as the light source, the edges are generally wide. The 40-inch ordinary LCD screen has a margin width of more than 11mm. If used for splicing, the splicing gap should be at least 22mm, which will affect the visual effect. The LCD splicing wall adopts a liquid crystal screen with a narrow-edge structure design, and the edge is reduced by more than double, which does not affect the visual effect when used for splicing. The LCD splicing screen has ultra-narrow edges, the number of splicing can be selected arbitrarily (row (m) X column (n)), and the size of the screen also has a variety of options to meet the needs of different use occasions. The ultra-narrow edge of the LCD splicing screen can be customized according to the requirements of different users, and you can choose functions such as single-screen display, full-screen display, and arbitrary combination display. In view of the inconsistency of parameters between the LCD screen and the driving circuit of the LCD splicing screen, the Tianjin LCD splicing screen

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 on

What are the basic components of LCD?

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.
