What are the pixels of LCD?

Pixel is a kind of unit. Generally speaking, it is invisible to the naked eye. How can we see the pixels of LCD? That is, if the image of LCD is magnified several times, many small square dots will be found. These small square dots are actually the so-called pixels.   The LCD splicing unit of LCD is a full-color screen, and red, green and blue are the primary colors of colors. Because LCD has many colors to realize, it needs to combine the red, green and blue lights to form pixels.   The pixel of LCD is a unit used to calculate the digital impression. Just like the photo taken, the digital impression also has continuous tone. If you enlarge the impression several times, you will find that these continuous colors are actually composed of many small dots near the color.   In addition, the pixels of LCD include real pixel display and virtual pixel display. The two technologies are different. The virtual display adopts virtual pixel technology, that is, LCD multiplexing technology. The same LCD light-emitting tube can be combined 4 times with adjacent LCD light-emitting tubes (down, down, left, and right combinations). Generally speaking, the pixel is a unit. The pixels of the current LCD display are 1920 * 1080, and the pixels of the Department display can be as high as 3840 * 2160. The higher the pixel, and more clearer the picture will be.

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

Advantages and precautions for use of small-pitch LED display

The small-pitch LED display has the characteristics of high refresh, high grayscale, high brightness utilization, no image retention, low power consumption, and low EMI. It is not reflective for indoor applications, and the display contrast is as high as 5000:1; it is lightweight and ultra-thin, High precision, small space for transportation and use, quiet and efficient heat dissipation. Small-pitch LED display products have a wider color gamut space and faster response speed than ordinary large LED screens, and can realize seamless splicing and modular maintenance of any size. The whole picture played is uniform in color, high-definition lifelike, no abnormal display such as sweat spots and bright lines that are common on ordinary screens, and the picture switching is soft and does not flicker, and the picture quality is very delicate, which is close to the playback effect of a TV. The contrast ratio of 5000:1 can show excellent blackness when the screen is black, and it is the best among similar products. The biggest competitiveness of indoor high-density and small-pitch LED displays lies in the complete seamlessness of the large screen and the natural and true display colors. At the same time, in terms of post-maintenance, the LED large screen already has a mature point-by-point calibration technology. The large screen used for more than one or two years can be used to perform a one-time calibration of the entire screen. The operation process is simple and the effect is very good. When using a small-pitch LED display, pay attention
