At present, LCD splicing screens are becoming more and more mature in application industries such as indoor high-end command and control centers, dispatch centers, and monitoring centers. We all know that dust is harmful to the human body, but you certainly did not expect that dust will also do the same to LCD splicing screens. As an electronic product with extremely high technological content, LCD splicing has a great impact on it due to dust. The LCD splicing screen movement uses many optical components, and it is precisely the dust that damages the optical components the most. Contrast refers to the maximum brightness value that the large screen display unit can output divided by the darkest brightness value. When in a dark scene, the dust on the optical components will reflect stray light and project the light that should not be projected from the lens. The brightness of the dark part. Similarly, some light in the bright part will be blocked by dust, reducing the amount of light reflection and transmission, and reducing the brightness value of the bright part, the contrast will naturally decrease in the past. The color wheel of the LCD splicing screen is the main accessory for color processing, including a high-speed motor, which rotates at about 7200 revolutions per minute. If a lot of dust is attached to the periphery of the color wheel, it will affect the rolling of the color wheel, resulting in a decrease or instability of the color wheel speed, which

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

World is now changing and using new technologies to get high performance as well as cost effective solution. As in the past, SAMSUNG, LG, AUO, BOE, and other well-known LCD panel suppliers only provided fully finished panels, resulting in high costs. With the advancement of the LCD industry, the cost of a whole machine is now lower than the cost of an LCD panel. As a result, Clients are looking for another cost-effective solution to assure a reasonable profit. Then, in order to reduce the material cost of the External Frame, the Open Cell solution is developed, which helps up the expansion of small-scale companies in the LCD industry. So, what is open cell solution and how it’s going to make a cost effective solution? An Open Cell is just a part of LCD panel without backlight. As we all know that getting the fully finished LCD panel (Traditional LCD module product) from SAMSUNG, LG, AUO, BOE, and other well-known suppliers were expensive. But, if we use Open cell solution to assemble all parts by ourselves to achieve the complete LCD module panel that would be very cost effective. In another approach, the Open Cell solution will not only reduce the cost of the LCD screen, but will also make the entire machine thinner than before. Certainly, a solution with a cheaper cost and a more fashionable appearance is currently very popular. The Open Cell Solution products will be the dominant trend in the LCD sector in the near future.
