Description

Chapter 1 Product Introduction

• Common Cathode with Energy-Saving
  Common cathode is an energy-saving power supply technology for LED display, which can effectively solve the problems of high screen temperature and excessive power consumption of common anode circuit. the average temperature of the panel of the common cathode circuit is 15℃ lower than that of the traditional common anode circuit，and the power consumption is reduced by more than 20%.

• Quick assembly and disassembly, convenient and efficient
  Hidden handles, hard connections, concealed wire design, easy maintenance; fast lock connections on the side for quick assembly and disassembly, high flatness, slim cabinet, lightweight, convenient for transportation, saving time and labor costs.
• Collision-resistant design, safe and reliable
  High-quality collision-resistant top protection and soft masks are used, with good toughness and impact resistance, effectively protecting LED chips and enhancing the safety of athletes.

• Exceptional picture quality, excellent visual experience
  Screen brightness exceeding 5500 nits, clear visibility even in strong light; high refresh rate, high contrast, stable high-definition live images without ghosting, flickering, or ripples.

• High protection level
  The cabinet is designed with full waterproof aluminum, featuring corrosion resistance, high precision, good flatness, deformation resistance, and good heat dissipation. Three-in-one outdoor waterproof SMD LED chips, combined with advanced gel-filling technology, can achieve an IP66 protection level, with strong environmental adaptability for all-weather outdoor operation.
• Drive solution

It has top and bottom line concealment functions, high refresh rate, first-line dimming improvement, low grayscale color shift, and mura improvement functions.

Environmental Inspection	It should match temperature and humidity meter for LED display at installation site, to monitor its surrounding environment, so that it can find out if LED display being affected with damp, moisture, etc.
The Usage of LED display	1.The environmental humidity should be 10%RH~65%RH, it is suggested to turn on LED display one time each day, normal to use above 4 hours each time, to remove its damp.
	2.When the environmental humidity is above 65%RH, it should make dehumidification to environment, and it is suggested to work LED display above 8h each day.
	3.When LED display has not turned on for a long time, it should preheat LED display to remove moisture before use, to avoid damage LED because of damp, the specific method: 20% brightness to work for 2h, 40% brightness to work for 2h, 60% brightness to work for 2h, 80% brightness to work for 2h, 100% brightness to work for 2h, by this to gradually increase its brightness.

5.3 Acceptance Request and Method

Acceptance Request and Method for LED display

Item	Acceptance Request and Method
Brightness of LED Display	Switch LED display to work as full brightness, use light-gun to measure the brightness of LED display within 10 minutes. When measuring its brightness, the light-gun need be vertical to LED display, to adjust the distance of light-gun and LED display, ensure the view window, black area, cover above 16 pixels, adjust focal length, to ensure LED chip being able to clearly view in eyepiece, then measure and record brightness data.
Visual Angle	The one should stand on the angle of 140°, bottom angle 65°to LED display when making measurement, it is requested that LED display should not have obvious the problem of dark block.
