Abstract

A method for determining device-specific information for pixels to obtain an optimal display of fine structure monochrome images on an output display device, the method comprising determining a set of device-specific pixel input values that will cause the display system to display a corresponding set of target visual output intensities relative to the output display device, and determining a device-specific sub-pixel geometry for all the pixels of the output display device. Displaying for each of the pixels a selected visual output intensity relative to the output display device at a sub-pixel position according to a corresponding pixel input value will cause an optimal display of fine structure monochrome images to be displayed on the output display device.

Claims

1. In a display system operable to display a plurality of pixels, a method for determining device-specific information for pixels of an output display device to obtain an optimal display of fine structure images on the output display device, where each pixel includes a plurality of sub-pixels each defining a color component and having a position in a sub-pixel geometry, the method comprising:

displaying a plurality of regions on the output display device, including selecting a pattern for each region of the plurality of regions; and

receiving a user input selecting a region of the plurality of regions and from the user input determining a device-specific sub-pixel geometry from a plurality of possible sub-pixel geometries for the pixels of the output display device.

2. A system, comprising:

an output display device having illuminable pixels, where each pixel includes a plurality of sub-pixels each defining a color component and having a position in a sub-pixel geometry;

means for selecting a respective pattern for each region of a plurality of regions on the output display device and displaying the respective pattern in each of the plurality of regions; and

means for receiving a user input selecting one region of the plurality of regions and from the user input determining a device-specific sub-pixel geometry from a plurality of possible sub-pixel geometries for the pixels of the output display device.

3. A computer program product tangibly embodied in a machine-readable storage device for execution for execution by a programmable processor in a system having a display device operable to display a plurality of pixels, where each pixel includes a plurality of sub-pixels each defining a color component and having a position in a sub-pixel geometry, the product comprising instructions operable to cause the system to perform the actions of:

displaying a plurality of regions on the output display device, including selecting a pattern for each region of the plurality of regions; and

receiving a user input selecting a region of the plurality of regions and from the user input determining a device-specific sub-pixel geometry from a plurality of possible sub-pixel geometries for the pixels of the output display device.
