Abstract
Techniques for 3D back light units are described. In some possible embodiments, in a first time interval during which one or more back light units of a display system are turned off, a complete set of left pixel values in a left frame is outputted to a display panel of the display system. In some possible embodiments, in a second time interval during which the complete set of left pixel values in the left frame has been outputted to the display panel of the display system, the one or more back light units are turned on to illuminate the display panel and the second time interval is subsequent to, and is not overlapped with, the first time interval.
Claims14
A method comprising:
- in a first time interval during which one or more back light units of a display system are turned off, outputting a complete set of left pixel values in a left frame to a display panel of the display system;
- and
- in a second time interval during which the complete set of left pixel values in the left frame has been outputted to the display panel of the display system, turning on the one or more back light units to illuminate the display panel, wherein the second time interval is subsequent to, and is not overlapped with, the first time interval.
A method comprising:
- turning off, during a first time interval, at least one back light unit of a display system;
- outputting, during the first time interval, a complete set of pixel values for a frame of a single perspective to a display panel of the display system;
- and
- illuminating, during a second time interval, the display panel by the at least one back light unit to display the frame,
- wherein the second time interval is subsequent to, and is not overlapped with, the first time interval.
