What accessories are included in the price of the led display?

What accessories are included in the price of the led display? Here, Xiao Bian for the need to understand the price of led display friends to sort out the parameters and equipment package included in the price of 1 square meter 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 the p4LED display is 4mm, the point spacing of the extension photoelectric p3LED display That is 3mm, the dot pitch of the p2.5LED display is 2.5mm, and so on, how much is the P point spacing; the smaller the dot spacing, the more expensive the price, the clearer the display effect, the higher the pixel density, the more pixels The more precise the accuracy, etc.

2, LED chip size mil: mil is the size unit, a mil is one thousandth of an inch, 21mil is about 1 mm, 15mil, 25mil, 27mil are the common size specifications of 1W high power chip. In theory, the larger the chip, the greater the current and power it can withstand. However, the chip material and process are also the main factors affecting the chip power. For example, the CREE 27mil chip can withstand 1W to 3W of power.

3, LED display refresh rate: high-quality LED display refresh rate is generally 1920HZ / sec. The refresh rate of the LED display is the number of times the electron beam repeatedly scans the image on the screen. 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 constrained, only a display that achieves a high refresh rate at high resolution can be called a performance E show. [You can understand that the refresh rate is the number of times the screen is refreshed every second. When watching a movie, what we see is actually a pair of still pictures, just like putting a slide, why do we feel that the picture is moving, that is Because the human eye has a visual pause effect, the impression that the previous picture remains in the brain has not disappeared, and the latter picture follows, and the difference between the two pictures is very small. The screen is displayed, so we feel that the picture is moving. This pair of replacement pictures is refreshing. Suppose an action is completed by 20 pictures. We look a bit like cartoons, and this action is increased to 30. Zhang’s words seem to be much more natural, this is the refresh rate].

4, gray level: LED display logic output 16384, CRT vision 65536 gray.

5. Scanning method: There are many scanning methods for LED display. Scanning has little effect on the price and quality of indoor LED display. The price of outdoor LED display is affected by scanning mode, because the lower the scanning mode is. The higher the brightness, the more expensive the price! The indoor LED display scanning mode mainly has 1/16 sweep and 1/32 sweep; the outdoor is mainly 1/2 sweep (the product of this scan mode is p10 full color), 1/4 sweep, 1/8 sweep.

6, Z power consumption, average power consumption: indoor LED display Z high power is generally between 600W-1000W; outdoor LED display Z high power will be higher, generally between 700W-1200W; LED display The average power is 1/3 of the Z power.

7, pixel resolution: p1.6LED display one square meter pixel point is 288000 points; p2LED display one square meter pixel point is 250000 points; p2.5LED display one square meter pixel point is 160000 points; p3LED The pixel of one square meter of the display is 111111 points; the pixel of one square meter of the p4LED display is 62500 points. Then, the more pixels a square meter of LED display is, the more expensive it is? Of course, the more pixels per square meter, the more expensive the price and the higher the display effect.

8. Discrete out of control points: <0.0001 (pixel failure rate/discrete state), 1/10000 The loss point after two years is 2-3/10000.

9, viewing angle, IP65 protection level: LED display viewing angle ≥ 140 °, IP65 protection level is the outdoor waterproof display protection level parameters, indoor LED display protection level is IP40.

10, gold wire copper bracket, copper wire copper bracket and copper wire iron bracket: gold wire copper bracket refers to the LED light bulb is the gold wire package, the bracket is copper, the price of this package is the most expensive Copper wire copper bracket refers to the LED light bulb and the lamp bead (bracket) are all copper wire package; the copper wire iron bracket such packaging manufacturers have basically been eliminated, basically no such product.
