Which Domestic LED Display Manufacturer Is Better?

Which domestic LED display manufacturer is better? There are many LED display manufacturers in China, and the quality varies. Since LED displays play a vital role, consumers dare not be careless and want to find a suitable and reliable manufacturer. To meet your own needs, if you want to know which LED display manufacturer is better, you must first have a preliminary understanding of this product, so that you can better identify the quality of the manufacturer.

The luminous color and luminous efficiency of LEDs are related to the materials and processes used to make LEDs. Currently, there are three types of red, green and blue widely used. Because LEDs have low operating voltage, they can actively emit light and have a certain brightness. The brightness can be adjusted by voltage, and they themselves It is impact-resistant, vibration-resistant and has a long life, so there is currently no other display method that can match the LED display method in large-scale display equipment. A display screen made by putting red and green LED tubes together as one pixel is called a two-color screen or a color screen; a display screen that puts red, green, and blue LED tubes together as a pixel is called a three-color screen or a full-color screen. The pixel size of indoor LED displays is generally 2-10 mm. Several LED tubes that can produce different primary colors are often packaged into one. The pixel size of outdoor LED displays is mostly 12-26 mm. A pixel is composed of several single-color LEDs. The common finished product is called a pixel tube. A two-color pixel tube is generally composed of 3 red and 2 green, and a three-color pixel tube is composed of 2 red, 1 green and 1 blue. Regardless of whether LEDs are used to make a single-color, two-color or three-color screen, in order to display an image, the luminous brightness of each LED that constitutes a pixel must be able to be adjusted. 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 colors, and the more complex the corresponding display control system. Generally, the color transition of a 256-level grayscale image is very soft, while the color transition boundary of a 16-level grayscale color image is very obvious. Therefore, color LED displays are currently required to be made into 256 levels of grayscale.

Characteristics of LED display: A comprehensive understanding of the characteristics of LED display is to choose a cost-effective LED display. Compared with other large-screen terminal displays, LED display mainly has the following characteristics:

High brightness: The colors are rich and bright. The brightness of the outdoor display is greater than 8000mcd/m2. It is currently a large display that can only be used outdoors all day long;

Long life: LED life span is more than 100,000 hours (ten years);

Large viewing angle: the indoor viewing angle can be greater than 160 degrees, and the 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; it is easy to interface with the computer, supports rich software, is easy to operate and flexible, and the picture is clear and stable.

Display screen networking: One microcomputer can be used to control multiple display screens to display different contents at the same time, and the display screens can also work offline. It can display both text and graphic images, and the fonts and fonts are rich in changes.

So which domestic LED display manufacturer is better? I would like to recommend Helitong to everyone.
