Abstract

Various embodiments of a display system are disclosed. One embodiment comprises a panel having a set of drivers connected to a subpixel rendering circuit in which the number of data lines going to the drivers is less than the different number of color data sets generated by the subpixel rendering circuit. In another embodiment, the driver circuits and/or the subpixel rendering circuit are constructed on the panel, using the panel's thin film transistors.

Claims (18)

1. A display system comprising:

a panel, said panel comprising a repeating subpixel grouping, each subpixel comprising one of a group, said group comprising a first color subpixel, a second color subpixel and a third color subpixel; said subpixel grouping comprising a plurality of columns wherein at least a first and a third column further comprising an alternating pattern of subpixels of said first color and subpixels of said second color;

said subpixel grouping further comprising a second column of subpixels of said third color and said first and said third column comprising a checkerboard pattern of said first and said second color subpixels;

a set of drivers coupled to said columns of subpixels;

a subpixel rendering circuit coupled to said drivers, said subpixel rendering circuit to output first color data, second color data, and third color data to said first color subpixels, said second color subpixels, and said third color subpixels respectively; and

wherein said first color data, said second color data, and said third color data are output to said set of drivers with less than three data lines.

2. The display system as recited in claim 1 wherein said system further comprises:

a data selector to input said first color data and said second color data on a first input data line and a second input data line respectively; and

wherein said data selector is to output a serial stream of first color data and second color data on a first output data line.

3. The display system as recited in claim 1 wherein said system further comprises:

a data selector to input said first color data, said second color data, and said third color data on a first input data line, a second input data line, and a third input data line respectively; and wherein said data selector is to output a serial stream of first color data, second color data, and third color data on a first output data line.

4. The display system as recited in claim 1 wherein said panel comprises a liquid crystal display panel and said drivers are constructed on said panel with said panel's thin film transistors.

5. The display system as recited in claim 1 wherein said panel comprises a liquid crystal display panel and drivers an said subpixel rendering circuit are constructed on said panel with said panel's thin film transistors.

6. A display system comprising:

a panel, said panel comprising a plurality of a repeating subpixel grouping, each subpixel comprising one of a group, said group comprising at least a first color subpixel, a second color subpixel and a third color subpixel; said subpixel grouping comprising a plurality of columns wherein a first and a third column further comprising subpixels of said first color and subpixels of said second color;

said subpixel grouping further comprising a second column comprising subpixels of said third color and said first and said third columns further comprising a checkerboard pattern of said first and said second color subpixels;

a set of drivers coupled to said columns of subpixels;

a subpixel rendering circuit coupled to said drivers, said subpixel rendering circuit to output first color data, second color data, and third color data to said first color subpixels, said second color subpixels, and said third color subpixels respectively; and wherein said first color data, said second color data, and said third color data are output to said set of drivers with less data lines than data lines input into said subpixel rendering circuit.
