Systems and methods of subpixel rendering implemented on display panels
View Patent ↗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.
1. 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 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;
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 subpixel rendering circuit operates a first frequency and a second frequency, said first frequency utilized to generate said first color and said second color image data and said second frequency utilized to generate said third color image data.
2. The display system of claim 1 wherein said first frequency is lower than said second frequency.
3. 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 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;
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 subpixel rendering circuit inputs image data at a first frequency and outputs image data at a second frequency.
4. The display of claim 3 wherein said subpixel rendering circuit inputs first color, second color and third color image data at a first frequency and wherein said subpixel rendering circuit outputs first color, second color and third color image data at a second frequency, said second frequency being lower than said first frequency.
5. The display of claim 4 wherein said display further comprises a multiplexor, said multiplexor accepting image data from said subpixel rendering circuit and outputting image data to said drivers.
6. The display of claim 5 wherein said multiplexor accepts image data at said second frequency and outputs said image data at a third frequency.
7. The display of claim 6 wherein said third frequency is greater than said second frequency.
