LED Display Parameters

Detailed explanation of led display parameters

The term led display parameter is often mentioned by electronic engineers, to the real professional terms such as "blind spot rate, gamma correction, large load capacity, peak power (W/m2), regular unit points, and point spacing (mm)" What does it mean? Non-professionals or novices may not be very clear, here is a detailed analysis for everyone:

The blind spot rate is the number of unlit dots on a screen divided by the number of dots on the entire screen.

Large load capacity, how many points the control card drives should be changed?

Peak power (W/m2) is the power of a screen per square meter, and it is also the maximum power

Regular unit points are commonly used unit board points, such as 64 points*32 points, 32*16, 16*8, 64*16, etc.

The dot pitch (mm) is the center distance between each group of luminous tubes and each group of luminous tubes. LED display parameters:

1. Indoor screen series

The indoor screen area is generally less than a dozen square meters, and the dot density is high. It is used in non-direct sunlight or lighting environments, and the viewing distance is a few meters away. The screen does not have the ability to seal and waterproof. According to the control method and display color, it can be divided into the following types:

● Indoor full color video screen

★ Use independently developed point-by-point correction technology to ensure uniformity between points.

★ The light-emitting point of the display panel adopts a columnar flat-head light-emitting diode. After testing,

　 Both vertical and horizontal viewing angles can reach 150 degrees.

★ The reflector that constitutes the light board is made by opening the mold, and it is seamlessly matched with the luminous point, and the finished product can be

　 The surface height error is extremely small.

★ Using light-emitting diodes, the light-emitting brightness is 6-8 times that of the light-emitting chip.

★ The heat of the light-emitting diode is mainly dissipated from the metal pins, which determines the display panel

　 Has good heat dissipation performance.

★ Bad LEDs can be replaced one by one without affecting the use of other LEDs.

　 Reduce maintenance costs.

★ Using the latest technological level of video control system, the display color is bright and clear.
