摘要:
An inverted staggered (bottom gate) thin film transistor (TFT) for active matrix liquid crystal display is processed with three masks. The first mask is used to pattern a metal film on a glass substrate as the gate of the TFT, the scan line of the TFT array, and a portion of the data line of the TFT array. The second mask is used to form a TFT mesa with a gate dielectric layer, an a-Si layer as channel, and a heavily-doped n+s-Si layer for contacting the source and the drain of the TFT. A third mask is used to pattern the transparent conductive indium-tin oxide film as the pixel electrode, the source/drain electrodes of the TFT, and the interconnections of the data line.

Embodiments of the present invention set forth methods and systems for driving display devices. In one embodiment, a first set of image data to be displayed on a display panel is stored. During a first time period, a reset signal is asserted to set the display panel associated with a common panel voltage to a predictable state. Subsequent to the first time period, a control signal is asserted to load the first set of image data for a first subframe within a frame on the display panel, wherein this first set of image data is further adjusted by a first adjustable reference voltage. A designated light for the display panel is turned on to display the first set of image data in parallel with the storing of a second set of image data for a subframe within the frame to be displayed.

An organic light emitting device is formed by assembling a first substrate and a second substrate. The second substrate includes several sub-pixels. The first substrate includes several transistors and, for each subpixel, a first connecting electrode. The transistors are electrically connected to each other, and the first connecting electrode is electrically connected to the respective one of the transistors. Each sub-pixel includes a light-emitting region and a non light-emitting region. A second connecting electrode is formed within the non light-emitting region and projects toward the first substrate.

摘要:
An additional high quality insulating layer is grown over the substrate after the formation of the gate electrode of a thin film transistor (TFT). The growth temperature of the insulating layer can be higher than conventional method and the insulating layer is more free of pin-holes. After the insulating layer in the thin oxide region of the TFT is etched away, conventional fabrication processes are followed. The dielectric of the thin film oxide region is the same as that of the conventional TFT; but the dielectric in the vincinity of the thin oxide region, the crossovers of the data lines and the scan lines, and the gate dielectric layer of the TFT are now composed of the high quality insulating layer. The TFT structure can improve the yield of fabrication by confining the channel region in the shadow of the gate electrode to reduce the leakage photo-current, and by reducing the steps at cross-overs steps and interconnections to avoid open-circuit.
