VTRON Introduces VLED-II Video Wall

Chinese LED Video Display maker VTRON, part of the Wei Chong Group Co., Ltd., has launched the VLED-II second generation video wall. The VLED-II employs COB (chip-on-board) technology in which the LEDs are directly encapsulated into the PCB to create a very smooth surface.

According to VTRON, the VLED-II features the lowest dead pixel rate. The series comes in pixel pitches of 1.2mm, 1.5mm, and 1.8mm. The company contends that the second-generation LEDs in the VLED-II unit are densely packed in each module to form a more uniform image without glare. VLED-II modules can be tiled snugly together to form a seamless image.

VTRON says that the device’s matte coating produces softer images, and reduces light radiation, the moiré effect, and glare while giving unprecedented clarity to fine image details. According to VTRON, the display design also minimizes eye strain from long-term close-up viewing.

The company points out that the fabrication process for the VLED-II with enhanced circuitry, optical and thermal design does not use electroplating, reflow soldering or mounting. This special fabrication and display design translate to a much lower dead pixel rate in a VLED-II display unit compared to a conventional LED display.

In addition to the other improvements, the VLED-II improves the performance lifetime compared to the original VLED series. The larger LED chip size in a VLED-II display unit produces higher brightness and enables even heat dissipation. Also, VTRON says that the VLED-II has virtually no light attenuation, greatly prolonging the display lifetime and helping to maintain the consistent brightness. Finally, VTRON asserts that VLED-II consumes much less power than that of a conventional LED video wall.
