The KEYTECHLED Outdoor Common Cathode Full Color Aluminum Screen combines advanced energy-saving technology with superior performance for outdoor displays. Featuring Common Cathode design, it offers four-level energy-saving capabilities, reducing power consumption without compromising on brightness or color quality. The screen delivers real colors for more realistic and vibrant images, while its structure optimization allows for flexible installation to suit various outdoor environments. With a stable driving project and high protection, the screen ensures long-lasting durability and reliable performance in challenging outdoor conditions.
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%.
Structure optimization, flexible installation
It supports various installation methods such as floor-standing, hoisting, and wall-mounted. Modular design of module, box and power box, front and rear maintenance, hard connection, no structural installation, saving structural cost.
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.
Driving Project
Self-designed electronic circuit engineering board, double row tube, 32 capacitors，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.
Real color, more realistic picture
The refresh rate is up to 3840Hz, the high contrast ratio, the grayscale is above 16 bit, the picture is vivid and delicate, the brightness is stable and even, not dazzling or grainy. Red, green and blue three-in-one LED lamp beads, with good consistency, and the viewing angle can reach more than 140°.
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, working temperature -40 ℃ -80 ℃, can operate normally in the seaside environment for a long time, The ability to adapt to the environment is very strong, and it can work outdoors all day long.
