Patent ID: 8390536

Claim:
A display, comprising: a plurality of pixels, wherein each of the plurality of pixels is operably connected to a data line, a select line, and a current line, at least one pixel comprising two thin film transistors each transistor comprising a source, a drain and a gate, a first transistor having a gate connected to the select line and a source or drain connected to the data line; a second transistor having a gate connected to the drain or source of the first transistor and a drain or source connected to the current line, a capacitor, and a light emitting diode; a circuit external to the plurality of pixels, the circuit configured to actively control a current value for each of the pixels by adjusting a voltage of the data line according to drawn current from the current line such that a desired pixel current is set to be drawn from the current line by one of the transistors; wherein the circuit external to the plurality of pixels adjusts the voltage of the data line according to drawn current from the current line and wherein the circuit external sets the desired pixel current within a single pixel addressing period determined by the select line activating another one of the transistors; and wherein the circuit external actively controls and sets the desired pixel current while the current line concurrently provides current to other illuminated pixels connected to the same current line.
