Abstract
A hybrid spatial-temporal color (STC) 2D-3D display is proposed using a 120-Hz liquid crystal panel with two color filters and light emitting diode matrix backlight. 3D mode was added to a Two Fields and Two Color Filters (2F2CF) STC LCD without adding any hardware element. This new configuration has 1.5 times higher resolution and around 1.5 times higher light efficiency than other currently used commercial 2D-3D LCDs because only two color filters are used. The backlight power consumption could be further reduced by applying the local dimming technology. The performances of the display with different backlight resolutions were analyzed with simulation on the aspect of image quality and power consumption. A perceptual experiment was also carried out to investigate the visual perception of stereoscopic impression, color nature and visual comfort by simulating specially at 3D mode. To balance the image quality and cost, 18 × 32 backlight segments was suggested for the optimal configuration.
