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.

The difference between LCD splicing screen and LCD display

With the popularization of the construction of national smart cities and safe cities, LCD splicing screens, as the best terminal display equipment, are favored by various industries and are perfectly integrated into our lives; as we all know, the LCD splicing industry is a sunrise industry with broad development. The prospects and entry barriers are extremely low. Therefore, the LCD splicing market has attracted an influx of many manufacturers, and the actual products of manufacturers are uneven. The viewing angle of the LCD splicing screen can reach 178 degrees, while the ordinary LCD can only see the 178-degree blank space. This is a very important criterion for distinguishing LCD splicing screens and LCD monitors. There is also the difference between the input signals of the two. The splicing screen is mainly the input video signal. In order to meet the interface requirements of different front-end devices, the splicing screen interface will be much richer than the display, including BNC, VGA, RGB, HDMI, DVI, S A variety of interfaces such as terminals meet the input requirements of different signals, while the monitor mainly inputs VGA signals, and the interfaces are mainly VGA, S-terminal, etc., which cannot meet the signal input requirements of various monitoring equipment. What is the difference between an LCD splicing screen and an LCD monitor, be sure to read it clearly when buying The driving scheme of LCD splicing screen is different, that is, the display motherboard scheme is different. Since the LCD display usually takes no more

What is the function of LCD Polarizer?

Polarizer is an important part of LCD screen. With the emergence of special full matching technology, polarizers are more and more widely used in LCD. What role does polarizer play in LCD?   Polarizer is widely used in LCD industry, and LCD needs to use polarizer. Polarizer and liquid crystal play an important role in development. In the production process, two pieces of ordinary tempered glass are printed on the circuit, and then glued together and folded. Then the liquid crystal is injected into the middle of the two sides of the glass, and the polarizer is pasted on the top and bottom of the glass.   The upper and lower glass should be pasted with polarizer, but pay attention to the direction. If the lower polarizer filters the x-direction light, the upper polarizer can only filter the y-direction light. If the upper polarizer filters out the light in the Y direction and the lower polarizer filters out the light in the X direction, the user can see nothing. Although the LCD works normally, the polarizer is not visible to the naked eye. Now the LCD color screen is generally only on the film, not on the film, the product technology innovation.   People who have studied physics should know what polarized light is. The imaging of LCD must rely on polarized light. All liquid crystals have two polarizers close to the liquid crystal glass to form a liquid crystal sheet with a total thickness of about 1 mm.
