3-D Reference 0h = Next Frame Left 1h = Next Frame Right |
The 3-D Reference is used to specify whether a frame of data contains left eye data or right eye data. The 3-D reference can be provide to the display as a hardware signal or by using this command (selection is made using the Write 3-D Control command in Write 3-D Control (20h)). When using this command as the reference, it is recommend that the command be sent every frame, or at least at the start of each eye pair (for example, sent before each left eye frame). At a minimum, it must be sent once at the start of 3-D operation. If the 3-D Reference is misaligned with the data, it can be corrected using this command or by using the polarity of 3-D Reference parameter in the Write 3-D Control command.
When the Write 3-D Reference command is received, the device applies its parameter value at the next VSYNC (that is, the parameter value is applied to the image data following the next VSYNC or Start of Frame command).
When this command is received, software establishes the internal controller 3-D reference generator. If the command is sent every frame, software can monitor to ensure that the output of the internal controller 3-D reference generator is still correct.
