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%.
• Four-level energy-saving technology
  Class I dynamic energy saving: when the signal is not displayed, turn off the driving circuit of the constant current tube chip;
  Level II black screen energy saving: when the display screen is completely black, the static consumption current of the chip drops from 6mA to 0.6mA;
  Level III full-screen energy saving: when the low level is maintained for 300ms, the static consumption current of the chip drops from 6mA to 0.5mA;
  Class IV shunt power supply and step-down energy saving: the current first passes through the lamp bead, and then goes to the negative electrode of the IC, so that the forward voltage drop becomes smaller and the on-resistance becomes smaller.
• Real color, more realistic picture
  The refresh rate is up to 3840Hz, the contrast ratio is up to 5000:1, and the grayscale is above 16 bit. Red, green and blue three-in-one LED lamp beads, with good consistency, and the viewing angle can reach more than 140°.
• Structure optimization, flexible installation
  Provide a variety of sizes of cabinets to choose from, different sizes of cabinets can be spliced with each other, and support various installation methods such as floor-standing, hoisting, and wall-mounted. Detachable power supply box, hard connection, front and rear maintenance, to meet the needs of different customers.
• Driving Project
  It has the function of list up and down hidden, high refreshing ratio, dark dot amended in first line, low grayscale amended, color cast and spot amended, etc.
• Stable and high protection
  Outdoor application products, IP66 protection grade, integrated all-aluminum design, with corrosion resistance, high melting point, flame retardant and fire resistance, moisture resistance and salt spray resistance, can operate normally in the seaside environment for a long time, strong environmental adaptability, outdoor all-weather work.
• Stable and reliable performance
  Ultra-low temperature rise, low power consumption, low attenuation, and the good thermal conductivity of the aluminum module itself, make the heat dissipation effect of the whole screen better, no need to install air conditioners, high reliability and long service life.

Item	User Manual
Electrostatic Protection	The installer need wear electrostatic ring and electric gloves, each equipment should take ground connection well when installing.
Connection Type	There are positive and negative electrode silk printed on module, don’t allow to reverse connect, and prohibit to connect with AC 220V.
Operate Type	Prohibit to assemble module, cabinet and whole of display under power on, operation should be under power off completely, to protect personal safety; Prohibit anyone to touch when the LED display is working, in case the static electricity which is generated by body to break through LED and other components.
Dismantle and Transportation	Don’t allow to throw, push, compress module, to prevent module falling down, to avoid breaking kit, damage LED chips, etc.
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	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.
	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.
	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.
