Stereoscopic display device and method for driving a stereoscopic display that updates a plurality of display zones

摘要

A first display zone and a second display zone are displayed based on a first light source group, which corresponds to a first voltage data signal; and then the second display zone and a third display zone are displayed based on light for a second light source group, which corresponding to a second voltage data signal. The first light source group and the second light source group illuminate the display zones alternatively. Each display zone is fed with either a first data voltage signal or a second data voltage signal. While the first data voltage signal is updating each display zone in sequence, the second data voltage signal starts updating the first display zone when the first voltage signal is updating the third display zone.

1. A stereoscopic display, comprising:
a display unit, comprising a plurality of pixels arranged in a plurality of pixel rows and a plurality of pixels columns comprising:
a first display zone and a second display zone, wherein said display unit updates a first display zone before updating said second display zone;an odd set of pixel columns; andan even set of pixel columns;wherein a scan line updates each pixel row in series to alternate between:
an LR frame, displaying an LR mode wherein said odd set of pixel columns display left eye data and said even set of pixel columns display right eye data; andan RL frame, displaying an RL mode wherein said odd set of pixel columns display right eye data and said even set of pixel columns display left eye data; a light shield, disposed in front of said display unit, comprising:
a first shielding unit, configured to block said even set of pixel columns from a left eye of a viewer and to block said odd set of pixel columns from a right eye of the viewer when said first shielding unit is disabled; anda second shielding unit, configured to block said odd set of pixel columns from said left eye of the viewer and to block said even set of pixel columns from said right eye of the viewer when said second shielding unit is disabled; and a backlight module, disposed behind said display unit, comprising a plurality of mutually exclusive light source groups that illuminate alternatively, each light source group corresponding to a discrete subset of adjacent pixel rows, wherein only the farthest light source group from said scan line illuminates an illuminated set of pixel rows, a top scan line being considered adjacent to a bottom scan line; wherein said first shielding unit is disabled when said illuminated set of pixel rows display said LR mode and enabled when said illuminated set of pixel rows display said RL mode, and said second shielding unit is disabled when said illuminated set of pixel rows display said RL mode and enabled when said illuminated set of pixel rows display said LR mode, wherein after said first display zone is updated, then a first light source group of said plurality of mutually exclusive light source groups is enabled to illuminate said first display zone, and wherein after said second display zone is updated, then a second light source group of said plurality of mutually exclusive light source groups is enabled to illuminate said second display zone.
