Abstract
Recent upgrades of HDTV into 3DTV resulted in impairments in displaying stereo contents. One of the most critical flaws is probably crosstalk and the resultant ghosting effect impairing the 3D experience. The purpose of this study is to identify the primary source of crosstalk, throughout the full image generation and viewing chain, for a selection of 3D displays: Liquid Crystal Display (LCD) and Plasma Display Panel (PDP) combined with different active glasses technologies. Time measurements have been carried out on various display panels and shutter glasses technologies. For each technology, the crosstalk is a complex combination of several factors depending on display panels, shutter glasses and their synchronization, and ghost busting. The study tried to discriminate the main sources of crosstalk in each case, and to simulate the effect of various display panels or shutter glasses performance optimizations. Analysis and conclusions vary depending on the display technology. For LCD, light leakage at the panel level appears the first cause of crosstalk, and, in a second step, optimization of the shutter glasses. For PDP the use of more adapted shutter glasses can mitigate color distortion effects.

Summary
In the main context of 3DTV or 3D games developments, it is crucial to analyze and well understand the technical characteristics of 3D displays with the goal to identify solutions for an improved 3D experience. The resulting ghosting effect often strongly impairs the quality of the 3D experience This technical contribution aims at studying the crosstalk effect in the context of active glasses 3D displays and suggesting some improvements. Chronograms are similar for other columns A, B, D or E These C1 to C5 chronograms, represented with dashed curves on Figure 14, have been measured for a maximal backlight level and, this way, present a maximal temporal extension. These C1 to C5 measurement curves change in shape and show a temporal shift depending on their position on screen (row 1 to 5). This corresponds to the bottom to top backlight scanning characteristics in the display
