Abstract
A method includes storing an analog indication of a terminal voltage of a pixel cell. A second indication of an incremental update to the terminal voltage is received, and the analog indication is used to modify the terminal voltage to reflect the incremental update. The pixel cell may form part of a display panel.
Claims24
A method comprising:
- providing a signal line accessible to a plurality of pixel cells;
- providing a signal to the signal line, the signal indicating an incremental intensity update to a terminal voltage of one of the pixel cells without reference to the terminal voltage;
- selecting one of said plurality of pixel cells;
- using an analog indication of the terminal voltage to modify the terminal voltage to reflect the incremental intensity update adding the analog indication of the terminal voltage to an analog indication of the incremental intensity update to produce a combined voltage;
- and transferring the combined voltage to the selected pixel cell.

A display panel comprising:
- pixel cells, each pixel cell being adapted to produce a different pixel of light having an intensity;
- a signal line accessible to the pixel cells to receive a signal, the signal indicating an incremental intensity update to a terminal voltage of one of the pixel cells without reference to the terminal voltage;
