(1) Common shade energy saving
Common negative, an energy-saving power supply technology for LED display, can effectively solve the problem of high temperature and power consumption of the common positive circuit screen body. The average temperature of the screen body of common negative circuit is 14.6ºC lower than the traditional common positive circuit, and the power consumption is reduced by more than 20%.
(2) Four-level energy-saving technology
Level I dynamic energy saving: when the signal is not displayed, the part of the drive circuit of the constant flow tube chip is turned off;
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;
Level IV shunt power supply step-down energy saving: the current first passes through the lamp bead, and then to the negative electrode of the IC, so that the forward voltage drop becomes smaller, and the conduction internal resistance also becomes smaller.
(3) True color, high-definition visual display
Refresh rate up to 3840Hz, grayscale 16bit, the screen display is realistic and delicate, not harsh, no grainy. Red, green, blue SMD LED beads, good consistency, viewing angle can reach more than 140 °.
(4) Structural optimization and flexible installation
Support floor, hanging, wall mounting and other installation methods. Modular design of module, case and power box, front and rear maintenance, hard connection, structureless installation, saving structural cost.
(5) Drive solutions
With column up and column down fading function, high refresh rate, first row darkening improvement, low gray off-color, pockmark improvement, etc.
(6) Stable and high protection
Outdoor application products, IP66 protection grade, integrated all-aluminum design, corrosion resistance, high melting point, flame retardant and fire resistant, moisture resistant and salt spray resistant, etc., working temperature -40ºC-80ºC, can operate normally in the seaside environment for a long time, with excellent environmental adaptability and outdoor all-weather work.
(7 ) Stable and reliable performance
Ultra-low temperature rise, low power consumption, low attenuation, plus the aluminum module itself has good thermal conductivity, so that the whole screen has better heat dissipation, no need to install air conditioning, high reliability and long service life.
