    摘要: Driving method and circuit of an organic light emitting diode, applied to an array of a plurality of organic light emitting diode. The array has several rows and columns of organic light emitting diodes. The row and column corresponding to the organic light emitting selected to illuminate are selected. A first voltage is applied to the selected column, and a second voltage is applied to the selected row. The difference between the first and second voltages is larger than the conducting voltage of the organic light emitting diode, so that the light emitting diode can illuminate. A third voltage and a fourth voltages are applied to other rows and columns which are not connected to the selected organic light emitting diode to provide a reverse bias to all the remaining light emitting diodes.

    摘要: In a display device in accordance with the present invention, each pixel includes a plurality of luminescent elements having different luminous intensities to represent gray scales by controlling the turning ON/OFF of the luminescent elements. A digital signal is transmitted to each pixel to carry out control by thin film transistors connected in series with the luminescent elements. The luminous intensities of the luminescent elements are the geometric progressions of a common ratio of 2. The ON resistance of the thin film transistors is set to be lower than the ON resistance of the luminescent elements, while the OFF resistance of the thin film transistors is set to be higher than the OFF resistance of the luminescent elements. These features have reduced the nonuniformity in the luminous intensities of the luminescent elements caused by the nonuniformity in the conductance of the transistors, thus achieving improved image quality.

    摘要: An addressing scheme for use with current-driven emissive displays requires that an N-row by M-column array of pixels be divided into K segments of N/K rows each. One transistor-controlled current driver is provided for each column of pixels within a segment, and all of a segment's current drivers are connected to a respective gate address line. The array is addressed by dividing a frame time into N/K “sub-frame” times. During the first sub-frame time, the current drivers of each segment are turned on in sequence, and the first row of each segment addressed. The remaining rows are addressed in this manner during subsequent sub-frame times. The segmenting and addressing scheme reduces the duty ratio required to drive the array by a factor of K, and reduces the number of transistors required to drive the array by a factor of N/K, when compared with comparably-sized passive matrix and active matrix displays, respectively. Fabrication of the display, and other non-passive matrix displays, is simplified by placing all active components on the back side of the display panel, or on a separate printed-circuit board (PCB) which is interconnected with the pixel array via respective surface bonding pads to form a display. Fabrication is further simplified by combining the current drivers and other drive electronics into application-specific integrated circuits (ASICs).

    摘要: A junction-based field emission display, wherein the junctions are formed by depositing a semiconducting or dielectric, low work function, negative electron affinity (NEA) silicon-based compound film (SBCF) onto a metal or n-type semiconductor substrate. The SBCF can be doped to become a p-type semiconductor. A small forward bias voltage is applied across the junction so that electron transport is from the substrate into the SBCF region. Upon entering into this NEA region, many electrons are released into the vacuum level above the SBCF surface and accelerated toward a positively biased phosphor screen anode, hence lighting up the phosphor screen for display. To turn off, simply switch off the applied potential across the SBCF/substrate. May be used for field emission flat panel displays.

    摘要: A point source array generates an array of output beams defining a plurality of image pixels. A microlens array receives the output beams and direct them toward desired pixel locations. Either one or both of the point source array and microlens array are scanned over time to form an image of pixels. An image is composed of an array of image portions. Each image portion includes a plurality of pixels. For each image portion, there is a corresponding point source of light and a corresponding microlens. The corresponding point source and microlens scan light within the area of the image portion to generate all of the pixels for such image portion. The microlens array is an integral array. Each lens moves together with each image portion being scanned concurrently by the microlens array an point source array.

    摘要: A matrix array display device has an array of pixels on a substrate which each have a display element, such as an electroluminescent display element. An associated control circuit including a storage capacitor and a light sensing element are connected thereto for regulating charge stored on the capacitor and responsive, for example, to light emitted from the display element so as to regulate operation of the display element. The light sensing elements include thin film semiconductor devices each having a strip of semiconductor material with laterally-spaced, doped, contact regions and the associated storage capacitor is formed by a conductive layer extending substantially transversely of the strip over one contact region with intervening dielectric material. A predetermined relationship between the storage capacitor and photosensitive device characteristics is then ensured even though dimensional variations in component layers may occur due to manufacturing tolerances. Alternatively, the conductive layer may be provided at the side of the strip opposite the gate and used also as a shield for ambient light.

    摘要: A liquid crystal device using a simple matrix panel which is driven by seven level potentials including PV3, PV2, PV1, VC, MV1, MV2, and MV3 in 4-line simultaneous selection driving at a high duty n1. The bias ratio c1 at this time is (PV2−VC)/L/PV3. In 4-line simultaneous selection driving at a low duty n2, the liquid crystal device is driven by five levels including PV2, PV1, VC, MV1, and MV2 by stopping the operation of third and fourth voltage raising circuits (230) and (232). The bias ratio c2 at this time is (PV2−VC)/L/PV2. When changing the duty, the relation n1·c12=n2·c22 is satisfied. This eliminates the need for contrast adjustment each time the duty is changed. A voltage-raising multiplying factor “k” in a third voltage raising circuit (230) satisfies the relation k=PV3/PV2. Therefore, n2=n1·(c1/c2)2=n1·(1/k)2 is realized.
