Abstract: A technique to reduce the rate of increase in threshold voltage, i.e. degradation, of an amorphous silicon TFT driving an OLED. A first supply voltage is supplied to a drain of the TFT when a first control voltage is applied to a gate of the TFT to activate the TFT and drive the OLED. However, a second, lower supply voltage is supplied to the drain of the TFT when a second control voltage is applied to the gate of the TFT to deactivate the TFT and turn off the OLED, whereby a voltage differential between the drain and the source when the second control voltage is applied to the gate is substantially lower said first supply voltage. This reduces degradation of the TFT. According to one feature of the present invention, when the TFT is turned off by the absence of voltage applied to its gate, the voltage at the drain of the TFT is reduced to approximately zero to minimize the voltage differential between the drain and the source.

Abstract: The present invention features designs of pixels and designs of control features for seals on AMLCD tiles optimized for tiling AMLCD flat panel displays (FPDs) which have visually imperceptible seams. The FPD structure has an image view plane which is continuous and remote from the pixel apertures or image source plane on the inside of the tiles. The image is formed on the view plane by a distributed ultra low magnification flies-eye optical system (a screen) that is integrated with the tiles, effectively excluding and obscuring an image of the seams. The innovations described herein minimize the defects on the perimeter pixels by effectively damming the waviness of the front of the seal near the perimeter pixels on the tiles. Dark space required for the seal between the interior tile edges and active regions of the pixels is decreased, as is the space allocated for wiring thereby increasing the feasible aperture ratios near the mosaic edges and all apertures.
