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 screens, 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 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 display devices. The display screen made by putting red and green LEDs together as one pixel is called two-color screen or color screen; the display screen made by putting red, green and blue LED tubes together as one pixel is called three-color screen or full-color screen. The pixel size of the indoor LED display 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 the outdoor LED display 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 screen. 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, 256-level grayscale images have very soft color transitions, while 16-level grayscale color images have obvious color transition boundaries. Therefore, color LED displays are currently required to be 256-level gray.
Features of LED display screen: to fully understand the characteristics of LED display screen is to select high cost-effective LED display screen. Compared with other large screen terminal displays, LED display screen mainly has the following characteristics:
High brightness: the brightness of outdoor display screen is more than 8000 MCD / m2, which can only be used in outdoor all-weather;
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, and clear and stable images.
Display networking: One computer can control multiple display screens to display different content at the same time, and the display screen can also work offline. Both text and graphic images can be displayed, and the font and glyph can be varied.
