发明名称 3-D silicon on glass based organic light emitting diode display
摘要 An organic light emitting display includes an organic light emitting diode that further includes an anode metal connected to a transparent cathode. An organic diode stack further comprising: electron-transport layer, hole transport layer and the emission layer organized into deep trench high aspect ratio structures in a bottom plane of the organic light emitting display and sandwiched between and the anode and cathode layers described above. A first stratum of thin transparent silicon that is attached to a diode plane in the organic light emitting display through a high aspect ratio via. A second stratum of thin transparent silicon that is attached to the first stratum and forming addressing transistors for the devices on the first strata. The organic light emitting diode emits light in response to bias voltages existing on the first and second strata that is extracted through a sub-pixel pitch microlens film deposited on the glass substrate.

主权项 1. An organic light emitting display, comprising: an organic light emitting diode further comprising: an anode metal connected to a transparent electrode of indium tin oxide forming an indium tin oxide layer; a three layer organic diode stack further comprising: electron-transport layer, hole transport layer and the emission layer organized into deep trench high aspect ratio structures in a glass substrate of the organic light emitting display; a first stratum of thin transparent silicon, attached to the organic light emitting diode in the organic light emitting display through a high aspect ratio via; a second stratum of thin transparent silicon, attached to the first stratum and forming driving and addressing transistors for the devices on the first strata; wherein the organic light emitting diode emits light in response to bias voltages existing on the first and second strata; a compensated pixel circuit, further comprising: a silicon-oxide-nitride-oxide-silicon charge-trapping non-volatile memory cell electrically coupled to a trim line and the data line; a first fully-depleted silicon-on-insulator transistor electrically coupled to the scan line and the silicon-oxide-nitride-oxide-silicon charge-trapping non-volatile memory cell; a second fully-depleted silicon-on-insulator transistor electrically coupled to the first fully-depleted silicon-on-insulator and a power supply; a third fully-depleted silicon-on-insulator transistor electrically coupled to the second fully-depleted silicon-on-insulator transistor, the power supply and the organic light emitting diode; wherein each silicon-oxide-nitride-oxide-silicon charge-trapping non-volatile memory cell further comprises a non-volatile memory cell transistor, configured to store two bits per cell and have resistance modulated to introduce an offset in a driver bias current to compensate for manufacturing process variations in the organic light emitting diode.
