Hisense Introduces New Display Tech at CES 2019 With ULED XD
China-based Hisense came out at CES 2019 with quite an ingenious new display solution that has (speculatively) a much better chance of faster PC monitor integration that OLED. OLED's implementation in PC monitors has been excruciatingly slow despite recent developments of the technology - mainly due to some underlying problems for PC's mostly fixed-image use-cases with its UI elements. As a result, display technology in the monitor space has been somewhat stagnant. Hisense, with its dual-panel ULED XD solution, whoever, could have a much cheaper and easier to implement solution that could bring another technology player to the PC monitor market.
The ULED XD solution basically crams two panels in front of the LED array. One is a 4K, RGB VA panel. This is your run-of-the mill implementation. However, there's a second panel sandwiched between the RGB and LED array in the form of a greyscale, 1080p resolution panel. What does this particular implementation offer, you ask? Well, it just so happens that different lighting conditions across the same RGB image are expanded upon by the grayscale monitor, even if it works at a lower resolution - it only serves to increase contrast if high and low luminosity areas, with black areas being supported by the blacks of the grayscale monitor. And even at that resolution, look at these as local dimming zones - over 2 million of such across a single panel.
