What accessories are included in the price of led display? Here, the editor has sorted out the parameters and equipment included in the price of 1 square meter of LED display for friends who need to know the price of LED display:

  1. LED display point spacing: LED display point spacing refers to the distance between the lamp bead and the lamp bead on the LED display module; for example: the point spacing of p4LED display is 4mm, and the point spacing of Tuosheng Optoelectronics p3LED display It is 3mm, the dot pitch of p2.5 LED display is 2.5mm, and so on, the dot pitch is as many as P; the smaller the dot pitch, the more expensive the price, the clearer the display effect, the higher the pixel density, the more pixel points , the precision is more dense, etc.

  2. How many mils are the LED chip sizes: mil is a unit of size, one mil is one thousandth of an inch, 21mil is almost 1mm, 15mil, 25mil, and 27mil are the common size specifications for 1W high-power chips. In theory, the larger the chip, the more current and power it can withstand. However, the material and process of the chip are also the main factors that affect the power of the chip. For example, a CREE 27mil chip can withstand 1W to 3W of power.

  3. LED display refresh rate: the refresh rate of high-quality LED display is generally 1920HZ/sec. The refresh rate of Tuosheng LED display screen refers to the number of times the electron beam scans the image on the screen repeatedly. The higher the refresh rate, the better the stability of the displayed image (picture). The refresh rate will directly determine its price, but since the refresh rate and resolution are mutually restricted, only a display that achieves a high refresh rate at a high resolution can be called a performance E show. [You can understand this, the refresh rate is the number of times the screen is refreshed per second. When watching a movie, what we see is actually a pair of still pictures, just like a slideshow. Why do we feel that the picture is moving, that is Because the human eye has the visual stop effect, the impression of the previous picture left in the brain has not disappeared, and the next picture will follow, and the difference between the two pictures is very small, and one action requires many pictures. The screen is displayed, so that we feel that the screen is moving. The replacement screen is refreshing. Suppose an action is completed by 20 pictures, and we look a bit like a cartoon, and the action is increased to 30 Zhang's words, it looks more natural, this is the refresh rate].

  4. Gray scale: The logic output of LED display is 16384, and the CRT visual is 65536 gray.

  5. Scanning method: There are many scanning methods for LED displays. Scanning has little effect on the price and quality of indoor LED displays. The price of outdoor LED displays is affected by the scanning method, because the lower the scanning method, the higher the quality
