Product Description


This product adopts common-cathode power supply technology which different from traditional common-anode.
Common-cathode technology refers providing power to Red/Green &Blue leds separately, the current passes through the
leds and then to the cathode of IC and reasonably to reduce the positive voltage, low conduction resistance. This scheme
effectively reduces the power dissipation, greatly reduces the heat generated in the working process of the display screen,
and prolongs the lifespan of the display screen.


Product Features


⚫ 320x160mm common-cathode module, compatible pitch:CH4/CH5/CH5.7/CH8.
⚫ Low heat and well-distributed heat, great uniformity performance.
⚫ Fast heat dissipation, low temperature rise, effectively prolong the lifespan of display.
⚫ Well-distributed heat, no color cast, even in long-term use, remaining great display performance without distortion.
⚫ 2.8V, 3.8V dual power supply, reduce circuit loss, save power and energy.
⚫ Support calibration of brightness and chromaticity dot by dot.
⚫ High precision die-casting aluminum cabinet, great flatness.

Common-cathode Advantage

1. Providing power to red/green&blue LEDS separately and reasonably to reduce the power dissipation.
2. Decreasing the temperature rise, air-conditioner free, and lowering down input cost.
3. Reducing power consumption, saving energy and decreasing operation cost.
4. Well-distributed heat, invariable color temperature, no color cast and no color block, ensuring great color uniformity

5. Low Temperature Rise

On the white balance testing, temperature fluctuation of common-cathode display is slight.

(Compare that with common-athode display on the same testing condition and specification)

6. High Contrast Ratio

Adopt common-cathode LEDS, 10000:1 high contrast ratio, fine and smoothdisplay performance, perfectly fit to
outdoor environment


7. Low Power Consumption

Adopt dual channel power supply tech. based on different optical characteristics of RGB LED.
With smart IC control system, it distributes precise voltage to LED and driving IC saving 20 to
30% energy.(Comparing that with common-athode LED)

Q: What is the brightness, viewing angle and wavelength of the LED?
A: Luminous Intensity is equal to the amount of luminous flux emitted into a very small solid angle at a defined angular orientation from the light source. The measurement for luminous intensity is the candela. Symbol is Iv.
Viewing Angle is the total cone angle in degrees encompassing the central, high luminous intensity portion of the LED beam from the on-axis peak to the off-axis point where the LED intensity is 50% of the on-axis intensity. This off-axis point is known as theta one-half ( 1/2). Two times 1/2 is the LEDs' full viewing angle; however, light is visible beyond the1/2 point.
Wavelength is the distance between two points of corresponding phase and is equal to waveform velocity divided by frequency. It defines what color human eyes could recognize
Q: What is dominant wavelength? Please specify the ranges of wavelength in red, green and blue color respectively.
A: Dominant wavelength is defined as the best range of wavelength showing the most natural color recognized by human eyes. Researches indicate that fixed colors with wavelength of 620-630nm (red), 520-530nm (green) and 460-470nm (blue), in fact mixed in a particular proportion, can get the pure white. That is, in display field, people use luminous materials with above wavelength to make "compounded" white more natural.In order to get a good balance white led display, we specify the led colors with wavelength within 4nm for each color
Q: Which chip vendors are you buying from?
A: It depends on the Customer's requirement. We can purchase from Japan, Korea, Europe, USA. We are using chips mainly from Taiwan
Q: What is the chip size you're using for outdoor display? How about indoor display?
A: For outdoor display, we're using 12mil chip for red, 14mil for both green and blue. Regarding indoor display, 9mil for red, 12mil for green and blue are currently adopted
Q: How much will the brightness of LED drop down after 1000hrs?
A: Based on the result of aging test, the brightness decay of green LED is around 5%-8%, while blue is around 10%-14% and red is around 5%-8%
