Our Services
1. We have our own independent R&D department on existing
products for better maintenance, we still continue to develop
high-tech products. We have our own patented products.
2. Our products must pass strict quality control procedures.
3. We have advanced production equipment.
4. We use the raw materials are from domestic and foreign
well-known brand manufacturers.
5. After repeated tests before shipment.
Advantages
1. Long life: product life of up to 50,000 hours;
2. Nanosecond response time, brightness and color make it easy to
dynamically control: enables dynamic color changes and digital
control;
3. A large design space: the organic architecture can be realized
with the integration to only see the effect of light not seen
light;
4. Environmental protection: no toxic metals mercury, no infrared
and ultraviolet radiation;
5. Color: different wavelengths produce different colored light,
bright saturated, no filter, can control red, green and blue
primary colors to form a variety of colors, can realize full-color
gradients, and other color effects.
