Abstract: Organic LED displays are vulnerable to developing age dependent non-uniformities of emitted light across a display matrix; there is accordingly a need for rapidly and accurately correcting such non-uniformities in an initially calibrated display device. As the decay of emitted light follows an exponential law, change in light output can be predicted by accumulating (i.e. performing numeric integration) the driving current for each individual pixel during an elapsed time; then, based on such predicted change, the driving current can be adjusted for each pixel such to compensate the decay. Another possibility of correcting non-uniformities is also described, by arranging a photodetector, such as a camera, for measuring the light emitted gy different single pixels or groups of the same, whose size is made stepwise progressively bigger by adequate displacement of the photodetector along X, Y and Z axis, while correcting unevenesses at every step.

Abstract: A circuit design technique polysilicon thin-film transistor (TFT) circuitry produces circuits that are relatively less sensitive to threshold variations among the TFT's than circuits designed using conventional techniques. The circuit is designed such that thin-film transistors that are sensititve to threshold variations are made larger than other thin-film transistors in the circuitry to minimize threshold variations among similar transistors implemented in the circuit. In one embodiment, a pixel structure for an active matrix display device implemented in polysilicon includes two transistors, a select transistor and a drive transistor. The drive transistor in the pixel structure is a thin film metal oxide silicon (MOS) transistor that includes a gate to source capacitance sufficient to hold an electrical potential which keeps the transistor in a conducting state for an image field interval. One embodiment of the pixel structure includes only the select transistor and the drive transistor. The pixel storage capacitance is entirely realized by the gate to source capacitance of the drive transistor. Another embodiment of the pixel structure includes a capacitor which is much smaller than the capacitor of a conventional active matrix pixel structure. This capacitor holds the pixel in a non-illuminated state when the drive transistor is turned off. This pixel structure may be used with any display technology that uses an active matrix and stores image data on a capacitance in the pixel, including without limitation, organic light emitting diodes, electroluminescent devices, and inorganic light emitting diodes.

Abstract: A display device having features which enhance the contrast of displayed images includes a pixel structure that defines an active pixel area and an inactive pixel area. The display device may be an emissive device such as an OLED or electroluminescent device, a transmissive device such as a liquid crystal light-valve device or a reflective device, such as a Bistable, Reflective Cholesteric (BRC) liquid crystal device. The ratio of the active pixel area to the total pixel area is less than 50 percent. The display device includes a transparent cover plate having a black matrix formed on the viewer side of the cover plate. The display device may be a tiled display in which case the black matrix is formed on an integrator plate to which the individual tiles are bound to form the complete display device. For reflective or emissive display materials, the display device includes an electronics section including a circuit board which provides driving signals for the pixels of the display device. The electronics section is bound to the display section by an adhesive. To provide a light-absorptive background for the active pixel elements, the circuit board or the adhesive are colored black. The individual pixel elements of the display device include four sub-pixel components separated by portions of the inactive pixel area, which four sub-pixel components together define the active area of the pixel. A lens system is provided on the viewer surface of the display to concentrate light emitted by the active area of the pixel elements into a smaller area, thus decreasing the aperture of the display. Areas between the lenses on the viewer surface of the display are coated with a black material to form a black matrix. A black material is selectively deposited on the front cover plate before applying the metal row electrodes to prevent the row electrodes from providing a reflective surface to the viewer.

Abstract: A row-select circuit (118) for an organic light emitting diode display (116) propagates a gating pulse through a shift register. This gating pulse is synchronized with a system clock signal and is used to selectively apply a plurality of broadcast control signals to a selected row of pixels on the display (116). The line scanning circuitry (118) is controlled to clear and autozero the pixels in the display (116) either on line at a time or the entire image frame at a time. According to another aspect of the invention, the clearing of a row of pixels in the display (116) is performed over several line intervals before the row is autozeroed and loaded with new values. According to yet another aspect of the invention, the broadcast control signals may be adapted to achieve the best performance for each display device.
