Abstract
System and methods are disclosed for improving the off-normal axis viewing angle by applying different filters if one colored sub-pixel data is driven close to 100% luminance while other colored sub-pixel data is driven close to 50% luminance values. Systems and methods for adjusting the viewing characteristics of the display system are also disclosed.
Claims7
A method for sub-pixel rendering source image data onto a display, the steps of said method comprising:
- sub-pixel rendering said source image data;
- and
- substituting different filter kernels when a first colored sub-pixel data would be driven to substantially 100% luminance and a second colored sub-pixel data neighboring said first colored sub-pixel data would be driven to substantially 50% luminance such that said first colored sub-pixel data and said second colored sub-pixel data are driven to substantially closer luminance values.
A display system comprising:
- a graphics subsystem receiving source image data and outputting display image data;
- a display panel coupled to said graphics subsystem;
- and
- said graphics subsystem further comprising a sub-pixel rendering subsystem wherein said sub-pixel rendering subsystem applies a different filter kernel to a first colored sub-pixel that would be driven to substantially 100% luminance when neighboring second colored sub-pixels would be driven to substantially 50% luminance.
1 more element
A graphics subsystem for a display system comprising:
- an input to receive sub-pixel data;
- and
- a sub-pixel rendering subsystem configured to apply a different filter kernel to first colored sub-pixel data received from the input when the first colored sub-pixel data would be driven to substantially 100% luminance at the same time that neighboring second colored sub-pixel data received from the input would be driven to substantially 50% luminance.
