An overview of flaws in emerging television displays and remedial video processing

New display principles aim at supreme image quality. The temporal aspects of these devices sometimes remain underexposed in the literature, and the paper presents an overview of new artifacts and possible remedies with signal processing. We discuss typical artifacts due to the unfavourable properties of emerging television displays. We introduce a processing model that eliminates or at least reduces the various artifacts that result from temporal imperfections of CRTs with alternative scanning, liquid crystal displays (LCDs), tiled displays, plasma display panels (PDPs), and colour sequential displays. We conclude that knowledge of the motion in the scene, i.e. motion estimation, is essential to at least partially repair the often unfavourable temporal behaviour of these displays. Such repair is realistic, as these displays have appeared on the market at the moment motion vector estimation has come to maturity for consumer applications.
