摘要： This invention is related to a thin film transistor (TFT) array and method of making same, for use in an active matrix liquid crystal display (AMLCD) having a high pixel aperture ratio. The TFT array and corresponding display are made by forming the TFTs and corresponding address lines on a substrate, coating the address lines and TFTs with a photo-imageable insulating layer which acts as a negative resist, exposing portions of the insulating layer with UV light which are to remain on the substrate, removing non-exposed areas of the insulating layer so as to form contact vias, and depositing pixel electrodes on the substrate over the insulating layer so that the pixel electrodes contact respective TFT source electrodes through the contact vias. The resulting display has an increased pixel aperture ratio because the pixel electrodes are formed over the insulating layer so as to overlap portions of the array address lines.

摘要： This invention is related to an active matrix liquid crystal display (AMLCD) having a high pixel aperture ratio. The display has an increased pixel aperture ratio because the pixel electrodes are formed over the insulating layer so as to overlap portions of the array address lines. Both the manufacturability and capacitive cross-talk of the TFT-based device are improved due to the use of a photo-imageable insulating layer between the pixel electrodes and the address lines.

摘要： This invention is related to a radiation imager (e.g. x-ray imager) and method of making same. An insulating material having a low dielectric constant is provided in areas of overlap between collector electrodes and underlying TFTs, diodes, and/or address lines in order to improve the signal-to-noise ratio of the imager. The TFT array and corresponding imager are made in certain embodiments by coating the address lines and TFTs with a photo-imageable insulating layer which acts as a negative resist, exposing portions of the insulating layer with UV light, removing non-exposed areas of the insulating layer so as to form contact vias, and depositing storage capacitor collecting electrodes over the insulating layer so that the collecting electrodes contact TFT source electrodes through the contact vias. The resulting imager has an improved signal-to-noise ratio due to the low dielectric constant of the insulating layer.

摘要： A high aperture active matrix liquid crystal display (AMLCD) includes pixel electrodes in respective pixels which overlap adjacent address lines. The color filters are formed on the active substrate in a manner such that the filters also overlap the address lines and function as an insulating layer between the pixel electrodes and address lines in the areas of overlap. Accordingly, line-pixel capacitances are reduced and the resulting AMLCD is easier to manufacture. The total number of process step in manufacturing is reduced, and plate-to-plate (active to passive plate) alignment is much easier and less important.

摘要： An organic light emitting diode (OLED) array structure, and corresponding method of making same are provided. Each OLED pixel includes a first electrode on a substrate, a second electrode on a substrate, and an organic emission layer disposed between the first and second electrodes so as to emit visible light when a suitable potential is applied thereto by the electrodes. In accordance with certain embodiments of this invention, a step covering or coverage layer is provided over step or edge areas of the first electrode in order to reduce the structures susceptibility to breakdown at pixel edges thereby improving yields.

摘要： A backlit transmissive liquid crystal display including non-linear resistive thin film diodes (TFDs). Select address lines on the active substrate provide both conventional address line functionality, as well as acting as one of the electrodes for each thin film diode. Two such diodes are provided in each pixel in certain embodiments. Still further, black matrix material is provided between the aforesaid address line material and the substrate so as to form rows of stacks on the active substrate. The thin film diode semi-insulating material, the address line material, and the black matrix material are patterned together in a single step to form elongated rows (or columns) on the active substrate. In such a manner, the display has reduced ambient light reflections, and reduce photosensitivity. Furthermore, because the pixel electrode, which also functions as the top TFD electrode in each pixel, overlaps both the select lines and portions of the color filter, a high pixel aperture ratio of at least about 70% is provided. The TFDs may be MIM diodes in certain embodiments.
