Mapping image pixel data to drive a display panel by producing an on-axis luminance pattern which is dependent on image pixels and an off-axis luminance pattern which is wholly or substantially independent of the image pixels and wherein the display produces, using pre-selected drive signals, different on-axis luminance values for each group of pixels and, for each group of pixels, the off-axis luminance values are the same or similar. The display does not have multiple pixel configurations that give the desired on-axis luminance and give different off-axis luminances to one another. Adjacent pixels may be mapped to produce average on-axis luminance / brightness values. Compressed or modified image pixel data may be mapped. This produces a display in private mode; if a public mode is desired, a second mapping of image pixel data may be performed instead of the first mapping. The second mapping may produce on-axis and off-axis luminance patterns that are dependent on the image pixel data. The display may have a lower operating voltage / lower power consumption and may be switchable between a public display mode and a privacy display mode. |
