　　Changzhou Indoor Small Pitch Full Color Display Screen Seamless Splicing High Speed Calibration

　　What is the definition and advantages of indoor small pitch LED display screens? LED display screens are made up of LED beads, and small pitch LED display screens have a smaller distance between two lights. The traditional definition of LED display screens is the distance between two lights. For example, P4 has a distance of 4mm between two lights, P5 also has a distance of 5mm between two lights, and so on. The spacing between dots below P2. (including P2.) is collectively referred to as small pitch LED screens. The traditional meaning of Changzhou small pitch display screens includes P2, P1.923, P1.86, P1.667, P1.538, P1.25, P1.0.P0.9, and so on

　　Advantages of Changzhou indoor small pitch LED display screen:

　　1. Changzhou indoor small pitch LED display achieves "low brightness and high gray"

　　Human body induction lights are different from outdoor displays that require high brightness, refresh rate, and energy-saving requirements. Indoor displays require a decrease in brightness. Experimental tests have shown that from the perspective of human eye sensitivity, the brightness of LED (active light source) is twice that of passive light sources (projectors and LCD displays). Specifically, the brightness of small pitch LED entering the room is between 100-300cd/m2. For example, when the brightness of the display screen drops to 30% of its original brightness, there is almost no loss in the grayscale of the displayed image; When the brightness decreases to 20% or even 15%, the grayscale loss is also very small, and the display image is still clear and visible. This is now controlled by chips, using high refresh rate chips; The grayscale loss caused by reducing brightness needs to be achieved through technical supplementation.

　　2. Standard resolution of Wuxi small pitch LED display screen with signal source

　　Unlike outdoor displays, outdoor advertisers will select content suitable for playback based on the resolution of the display screen. Indoor display signal sources have certain standards, and as manufacturers, they cannot require indoor signal sources to adapt to the resolution of the display screen. Instead, they need to adapt to the needs of indoor signal sources, design and ensure the corresponding resolution, and meet the needs of users.

　　3. Wuxi high-definition indoor LED display screen supports system access and display control for multiple and complex signals

　　Compared with outdoor display signals, the characteristics of indoor LED displays are multi signal access and complex signal access. For example, in multi location video conferences, remote signal access, local signal access, and multi person access are required. Experiments have shown that simply implementing multi signal access through a split screen scheme will reduce signal standards. Therefore, how to solve the problem of multi signal and complex signal access still requires technical support for small pitch LEDs.

　　4. Changzhou small pitch LED display achieves seamless splicing and high-speed calibration

　　One major advantage of Wuxi's small pitch LED display screen is its seamless design, but it requires high standards for splicing. For LCD, as long as the stitching is uniform, there is no problem, and the seams are not obvious. But small spacing between LEDs is not enough. If the modules are squeezed too tightly, bright lines will appear, and when the modules leave, dark lines will appear. True stitching is not easy. Therefore, the process and calibration technology of the box body, as well as the guarantee and good combination of efficiency, need to be ensured.

　　5. Changzhou small pitch LED display reduces dead light rate and ensures the stability of the screen body

　　The traditional LED dead light rate is one in ten thousand according to industry standards, but small pitch LEDs currently cannot achieve it. If according to traditional standards, there is only one dead light per ten thousand square meters, and the display screen cannot be viewed. So the dead light rate of small pitch LED displays needs to be controlled to one in 100000 or even one in a million to meet long-term usage needs. Otherwise, after a period of use, the full screen will be dead lights, which users cannot accept. So it is necessary to ensure the stability of the screen during normal use.

　　6. Wuxi high-definition indoor LED display screen has ultra high definition and perfect picture quality, seamless splicing, and an exclusive visual feast. The ultra high technology aluminum magnesium zinc alloy box is harder than aluminum and more corrosion-resistant than iron. The multifunctional connector is fast, simple, and convenient, energy-saving, low brightness and high gray, and the picture is more delicate and easy to achieve FHD and 4K large screen.
