Detailed Description P3LED display: a, Appearance Product smallest unit of 400mm (width) * 300mm (H), the overall thickness of 76mm, weighs less than 5kg, cell structure with a new cast aluminum housing products, with light weight, high precision, fast heat dissipation, beautiful appearance, easy installation advantages. Second, the product features a high brightness and adjustable light sensing device can fit on the environment adaptive adjustments will not affect the strong ambient light display. 2, high contrast 1) LED TV with high-quality black surface of the LED lights, improve brightness, while reducing the brightness of the screen when black. 2) The company's unique black mask processing technology that allows the screen contrast and then get a great upgrade. 3, wide viewing angle vertical and horizontal viewing angle of 160 degrees in both directions, so that the viewer can get a variety of angles in high quality display. 4, the response time is short LED display response time is extremely short, in the nanosecond level, does not appear smearing, ghosting in motion video monitor screen and playing time, has a great advantage. 5, single-point calibration technique single-point calibration system will each display unit board each pixel individually controlled, including its brightness and color controls to gain unprecedented evenness, generated the most clear images. Single-point calibration procedure: 6, high reliability 1) Dual redundant power supply: Power supply in a certain way the fault of circumstances, can still ensure the normal operation of the box; 2) Dual Signal Hot Backup: hot backup with dual signal input, each unit box control module will automatically detect the integrity of the two input signals; 3) has a signal backhaul mechanism: the status of all currently running unit box back to the host computer can. 7, broadcast-level grayscale processing 1) low-brightness display grayscale almost perfect performance, image layering and vividness of their shows than traditional display; 2) can show more detail of the image, without loss of information. 8, truly seamless splicing technology 1) LED screen can be in any direction, any size, any shape stitching. Stitching projection and LCD compared to, there will be no difference in brightness between the units or black seam stitching, showing a perfect visual effect. Fine cell structure, to ensure the consistency of spacing. 2) Screen uniform, no separation, no black line, there is no missing information, the realization of a truly seamless mosaic screen. 9, ultra-high refresh rate 1), no ripple-free extract image stabilization black, coping dynamic display screen, the image sharp edges, good dynamic performance, the true image restore information is accurate. So delicate and smooth video images, the greatest visual enjoyment; 2) with inverse gamma correction technology, but also video recording with the original face images, the display screen is more real and natural; 3) LED screen brightness uniformity performed extremely well, with single point brightness correction, so that the entire screen brightness uniformity tends to the extreme. 10, the screen long life company has a long experience in manufacturing LED display, rich drive circuit design experience, combined with years of screen data and stable components to ensure LED from all aspects of the use of more long-term. 11, the PFC power supply more energy efficient 1) using switching power supply with a PFC function, the LED power supply system to reduce the circuit, the interference of various components of the power supply system caused by the original, clean the grid to improve the power quality; 2) with the use of PFC function of switching power supply, improve the power factor, but also reduces power loss big screen itself, save electricity, low carbon and environmental protection. 12, post lower maintenance costs under the LED display normally defect rate is very low, even if there is a fault or power supply modules are only carried out post-maintenance costs low. 13, LED Screen LED display smaller footprint advantage is small compared with the rear portion of the subsequent repair space, usually in less than 0.8m, can fit on the existing embedded in the wall, without changing the housing structure.
