Solid state emissive display with on-demand refresh

Abstract

A display device, including: a light controlling element; a drive circuit connected to the light controlling element, the drive circuit including a transistor having a gate for controlling the power applied to the light controlling element; a storage capacitor connected to the gate of the drive circuit transistor; a control circuit for depositing charge on the storage capacitor; a refresh circuit connected to the control circuit and responsive to an external signal for causing the control circuit to deposit charge on the storage capacitor; and a feedback mechanism including element for measuring a change in a performance characteristic of the display device and for signaling the refresh circuit in response to the measured characteristic, whereby the display is refreshed on demand as opposed to periodically.
