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
$\,\times\,$
32 backlight segments was suggested for the optimal configuration.
