Yaham's outdoor black LED display heightens realistic rendering of images and video

Aug. 13, 2015
Lately, the black LED display has achieved a new status not only in indoor applications but also in outdoor display applications. What is the difference between the black lamp and white lamp used in an LED display in practical applications?

An LED display based on a black lamp uses black packaging plastic stents, while the white-lamp-based LED display uses white packaging plastic stents. The former produces more unified color and higher contrast compared with the latter. With the increasing demand for the black LED display, some LED enterprises choose to increase their investment in black LED display production.

Yaham performed a contrast test between the DT10 white display and the DT10 black display; here are the technology parameters of the two displays.

Yaham's black lamp LED display is on the right; the left is the white lamp LED display, and the contrast effect is very obvious. The black display exhibits a higher contrast ratio and color fidelity.

DT10 is Yaham's top selling product, with a wider viewing angle, better consistency, higher contrast, and better oxidation resistance than DIP products. To provide better products for our clients and expand product diversity, Yaham has officially released the outdoor DT10 black lamp LED display. Black LED displays bring outdoor digital signage to a new level.

1. High contrast
Black shell bracket could improve the contrast at a maximum level, which exhibits vivid video images, and the color is more realistic.

2. True color
Yaham selects high quality outdoor SMD black LED lamps, which use matte technology to avoid reflective surfaces and resolve the problem of outdoor glare; at the same time it improves the quality of the picture.

3. Wide viewing angle
140°H/V, fabulous visual performance from various angles.

4. High consistency
From different angles, red, green, blue ensure the consistent brightness of the LED display in any viewing angle, which can achieve vivid effects.
