Optimization of backlight scanning on auto-stereoscopic display with spatial and sequential hybrid control
Auto-Stereoscopic with improved spatial and sequential hybrid control (SSHC) is a new type of auto-stereoscopic display technology which retains full resolution and low crosstalk ratio. It eliminates the temporal crosstalk caused by the non-synchronization between the screen and the backlight module
which is one of the key issues of auto-stereoscopic display with SSHC. The paper explains principles of auto-stereoscopic display with SSHC and dynamic backlight system. Two different refreshing strategies of backlight module are introduced
which are the scanning type and the vertical type. Comparison on the influences on the luminance and crosstalk ratio of the display system for both strategies is mainly discussed. The optimal settings for backlight module are achieved through experimental results. Experimental results show that the crosstalk ratio of the display system can be suppressed as low as 2.64% with the optimal settings
which proves that the dynamic backlight control technique can effectively lowers temporal crosstalk.
