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.

LCD screen will be widely used in many electronic products, one thing has been widely welcomed, and you will want to solve some problems, and pay attention to some things, let’s talk about how to pay attention to the anti-static problem of LCD screen? Electrostatic adsorption of dust reduces the insulation resistance of components and shortens the service life; Electrostatic discharge (ESD) damage, resulting in electronic components cannot work; the electromagnetic field produced by electrostatic discharge has a large amplitude and a wide frequency spectrum. Such electrostatic noise and electromagnetic interference make electronic equipment unable to work normally or even damaged.   Pay attention to:   The wristband should keep the body and the ground equipotential. ESD protection workbench should keep equipotential between device and ground. It is not allowed to place electrostatic insulating materials in the safe area .The circuit board with IC must be handled on the antistatic workbench. Wristbands and shoe covers should be tested every day to ensure that they meet the parameter requirements.   All instruments and equipment shall be grounded. Regard all components as electrostatic sensitive devices. Never touch sensitive devices or components without good grounding.   In the absence of other anti-static measures, do not take the IC installed in the anti-static tube. Use fixed-point ion eliminator in the process that may generate static electricity. If the IC is not on the process line or anti-static workbench, store them in a container with grounding shield. The gas and liquid flowing through IC should
