Abstract:
1. A display pixel, comprising: a first capacitor coupled between a first node and a second node; an initialization transistor coupled to the first node and configured to set the first node to a reference voltage responsive to turning on of the initialization transistor; a data transistor coupled to the first node and configured to set the first node to a data voltage responsive to turning on of the data transistor, the data transistor to set the first node to a data voltage after the initialization transistor sets the first node to the reference voltage, and setting the first node to the data voltage causes, via the first capacitor, a voltage change at the second node; a control transistor coupled to the second node and configured to set the second node to a supply voltage responsive to turning on of the control transistor, wherein setting the second node to the supply voltage causes, via the first capacitor, an adjustment in the data voltage at the first node to generate an adjusted data voltage at the first node; and a driving transistor, a gate of the driving transistor coupled to the first node and a source of the driving transistor coupled to the second node, wherein the adjusted data voltage at the first node is applied to the gate of the driving transistor to control current in a light emitting diode (LED).
