There are many full-color LED display manufacturers in the country, and the quality is uneven. Because the LED display plays a vital role, consumers are not sloppy and want to find a suitable and reliable manufacturer to meet their needs. If you want to know which manufacturer is good for LED display, you must first have a preliminary understanding of this product, so that you can better distinguish the quality of the manufacturer.

The luminous color and luminous efficiency of LEDs are related to the materials and processes used to make LEDs. At present, there are three types of red, green and blue that are widely used. Due to the low working voltage of LEDs, they can actively emit light and have a certain brightness. The brightness can be adjusted by voltage. Impact resistance, vibration resistance, and long life, so there is currently no other display method that can match the LED display method in large-scale display equipment. A display made of red and green LEDs as a pixel is called a two-color screen or a color screen; a display made of red, green, and blue LED tubes as a pixel is called a three-color screen or a full-color screen. The pixel size of indoor LED display screens is generally 2-10 mm. It is often used to package several LED dies that can produce different primary colors into a whole. The pixel size of outdoor LED display screens is mostly 12-26 mm. Each pixel is composed of a number of various monochromatic LEDs. The common finished product is called a pixel tube. The two-color pixel tube is generally composed of 3 red and 2 green, and the three-color pixel tube is composed of 2 red, 1 green and 1 blue. Regardless of whether LEDs are used to make monochromatic, two-color or three-color screens, the brightness of each LED constituting the pixel must be adjustable to display an image, and the fineness of the adjustment is the gray level of the display. The higher the gray level, the more delicate the displayed image, the richer the color, and the more complicated the corresponding display control system. Generally, the color transition of a 256-level grayscale image is very soft, while for a 16-level grayscale color image, the color transition boundary is very obvious. Therefore, color LED display screens are currently required to be made into 256-level grayscale.
LED display features: A comprehensive understanding of the characteristics of LED displays is to choose cost-effective LED displays. Compared with other large-screen terminal displays, LED displays mainly have the following characteristics:
High brightness: The colors are rich and bright, and the brightness of the outdoor display is greater than 8000mcd/m2, which is a large-scale one that can only be used outdoors all-weather at present;
Long life span: LED life span is more than 100,000 hours (ten years);
Large viewing angle: indoor viewing angle can be greater than 160 degrees, outdoor viewing angle can be greater than 120 degrees;
Modular structure: The screen area can be large or small, as small as less than one square meter, or as large as hundreds or thousands of square meters; easy to interface with computers, rich support software, convenient and flexible operation, clear and stable screen.
Display networking: One computer can control multiple display screens to display different content at the same time, and the display screens can also work offline. Both text and graphic images can be displayed, and the font and glyph can be varied.
