Liquid crystal display generally refers to some display screens made of liquid crystal. It is an active matrix liquid crystal display driven by thin film transistors (TFT). It is mainly used to stimulate liquid crystal molecules to generate dots, lines, and surfaces to match the back light. The tube constitutes the screen. IPS, TFT, and SLCD are all sub-categories of LCD. Today, the name LCD screen mostly refers to display screens used in notebook computers or desktop computer applications. So what is the difference between LED display and LCD display? The following editor Zhilingxin will introduce to you.
What is the difference between LED display and LCD display:
1. LED and LCD have different light emitting principles and different manufacturing processes. LED is a dense dot matrix composed of light-emitting diodes to form an image display. The image definition depends on the resolution of the light-emitting points, while LCD is composed of liquid crystal cells.
2. The LED display is suitable for display requirements with low definition, and the LCD is suitable for those with strict requirements on definition.
3, LED display screen is suitable for large display area, one hundred is more than 10 square; LCD splicing screen display is suitable for small area, generally less than 10 square.
4. The price of LED display is calculated by square, and the price of LCD is calculated by block or unit.
5. There are no obvious splicing seams on the overall LED display, and there are obvious splicing seams on the LCD splicing display, which seriously affects the appearance. At present, with the development of technology, LG has just launched a 0.9mm splicing gap product, this product is installed, there is only a black line in the gap, and the display effect is very good.
6. With the development of small lamp beads, LED can be made more high-definition. At present, it can achieve 0.9mm pitch. In some occasions, it can replace LCD display, but the same resolution is still not up to LCD display, and the unit price Super high, currently only suitable for large-area army combat maps, large-scale command centers, etc.
7. In terms of cost, the price of LED is determined according to the display pitch, and the price of LCD is determined according to the size of the splicing gap. It can only be compared with the existing conditions, and it is not very accurate.
