Embodiment Construction

[0026] Various embodiments disclosed herein relate to Active Matrix Diluted Source Realized Vertical Organic Light Emitting Transistor (AMDS-VOLET). Reference will now be made in detail to the description of the embodiments shown in the drawings, wherein like reference numerals indicate like parts throughout the several views.

[0027] Due to power saving, improved contrast ratio, and insensitivity to viewing angle, existing display technologies are gradually shifting in technology to active matrix organic light emitting diode (AMOLED) displays. The transition is hindered by the fact that the high drive currents required by organic light-emitting diodes (OLEDs) are supplied through thin-film transistors (TFTs) in the backplane. Using polysilicon (poly-Si) as the channel material is an option to achieve high drive current, but poly-Si brings high manufacturing cost and has non-uniformity problems. Organic semiconductor materials used as TFT channel materials may not be so expe...

Abstract

The invention relates to an active matrix dilute source enabled vertical organic light emitting transistor. Various embodiments are provided for dilute source enabled vertical organic light emitting transistors. In various embodiments, a display panel includes an array of pixels. In one embodiment, among others, at least one pixel includes a switching transistor and a driving transistor coupled to the switching transistor, where the driving transistor is configured to emit light responsive to activation by the switching transistor. The driving transistor may be a dilute source enabled vertical organic light emitting transistor (DS- VOLET). The switching transistor may include a dilute source enabled vertical-field effect transistor (DS-VFET). In another embodiment, a double dilute source enabled vertical-field effect transistor (DS-VFET) includes a first DS-VFET coupled to a second DS-VFET.
