The CH II is a new display from Dahua incorporating the company’s flip chip on board (COB) technology for LED displays. The company claims its surface luminescence provides softer, pixel-free illumination, which counters digital visual fatigue, and ensures uniform color from all viewing angles by perfecting ink color parameters, addressing and eliminating the industry challenge of batch ink color discrepancies.

The display is dustproof and fingerprint-proof, waterproof, moisture-resistant with PPM<20, and can withstand slight bumps without damage. It has a claimed contrast ratio of 10,000:1 and provides a 160° horizontal and 160° vertical ultra-wide viewing angle.
Dahua is emphasizing the energy efficiency, with each cabinet consuming less than 75W, claiming a 40% reduction in energy use compared to surface mount display (SMD) products. For the target audience of systems integrations, the CH II is supposed to provide simplified and quick maintenance with full front access.
