摘要： An active matrix display device has column address circuitry for generating pixel drive signals. The column address circuitry has an output buffer for providing a pixel drive signal to a column conductor, and the positive and negative slew rates of the output buffer are different. By selecting the positive and negative slew rates independently in the design of the output buffer, the size of the transistors (54, 56), particularly those which pass the charging (or discharging) current of the column capacitance, can be kept to a minimum.

摘要： Each pixel of an active matrix electroluminescent display device has a first amorphous silicon drive transistor for intermittently driving a current through the display element and a second amorphous silicon drive transistor for intermittently driving a current through the display element. The aging effect of amorphous silicon TFTs can be reduced by sharing the driving of the display element between two drive transistors. Providing a duty cycle reduces the on-time for each drive transistor, but also provides a period during which there can be some recovery of the TFT characteristics.

摘要： An active matrix pixel device is provided, for example an electroluminescent display device, the device comprising circuitry supported by a substrate and including a polysilicon TFT (10) and an amorphous silicon thin film PIN diode (12). Polysilicon islands are formed before an amorphous silicon layer is deposited for the PIN diode. This avoids the exposure of the amorphous silicon to high temperature processing. The TFT comprises doped source/drain regions (16a,17a), one of which (17a) may also provide the ntype or p-type doped region for the diode. Advantageously, the requirement to provide a separate doped region for the photodiode is removed, thereby saving processing costs. A second TFT (10b) having a doped source/drain region (16b,17b) of the opposite conductivity type may provide the other doped region (16b) for the diode, wherein the intrinsic region (25) is disposed laterally between the two TFTs, overlying each of the respective polysilicon islands.

摘要： A method is provided of determining the pixel drive signals to be applied to the pixels of an array of light emitting display elements arranged in rows and columns, with a plurality of the pixels in a row being supplied with current simultaneously along a respective row conductor. Target pixel drive currents are determined from a model of the pixel current-brightness characteristics. These are modified to take account of the voltage on the respective row conductor at each pixel resulting from the currents drawn from the row conductor by the plurality of pixels and the dependency of the pixel brightness characteristics on the voltage on the row conductor at the pixel. This addresses the problem of horizontal cross-talk that occurs in active matrix 1.RD displays due to the finite output impedance of the current providing TFT's as well as the finite resistance of metals used to form power supply lines.

摘要： A display device has a plurality of pixels, each pixel having a current-driven display element (2) coupled between a first conductive layer (28) and a second conductive layer (27), the second conductive layer (27) being coupled to a current supply (26) via a switchable device (12) having a thin film component (122) on a first area of a substrate (120). Each pixel further has a first capacitive device having a first capacitor plate (132) on a second area of the substrate (120), the first capacitor plate (120) being conductively coupled to the thin film component, a second capacitor plate (133) and a first insulating layer (130) between the first capacitor plate (132) and the second capacitor plate (133). Stacked on top of the first capacitive device is a second capacitive device sharing the second capacitor plate (133) with the first capacitive device, the second capacitive device further comprising a third capacitor plate comprising at least a part of the second conductive layer (27), and a second insulating layer (140) between the second capacitor plate and the third capacitor plate. This arrangement benefits from larger capacitances for the first capacitive device and the second capacitive device, making them more robust against the influences of parasitic capacitances.

摘要： An active matrix display device, particularly a liquid crystal display device, having an array of display pixels (25) driven with inverting polarity drive voltages includes correction means (40, 55) for providing a measurement indicative of a DC voltage level at the pixels (25), for example caused by kickback effects, and modifying pixel drive voltages accordingly so as to compensate for any display artefacts.

The correction means is then able, for example, to account for variations in pixel DC levels over the array.

摘要： Each stage of a shift register circuit has a first input (Rn−1) connected to the output of the preceding stage, a drive transistor T(drive) for coupling a first clocked power line voltage (Pn) to the output (Rn) of the stage, a compensation capacitor (C1) for compensating for the effects of a parasitic capacitance of the drive transistor, a first bootstrap capacitor (C2) connected between the gate of the drive transistor and the output (Rn) of the stage; and an input transistor (Tin1) for charging the first bootstrap capacitor (C2) and controlled by the first input (Rn−1). Each stage has an input section (10) coupled to the output (Rn−2) of the stage two stages before the stage having a second bootstrap capacitor (C3) connected between the gate of the input transistor (Tin1) and the first input (Rn−1). The use of two bootstrapping capacitors makes the circuit less sensitive to threshold voltage levels or variations, and enables implementation using amorphous silicon technology.

摘要： In an active matrix display, each pixel has a storage capacitor for storing a voltage to be used for addressing a drive transistor. A discharge transistor is provided for discharging the storage capacitor thereby to switch off the drive transistor. The timing of this is controlled by a light-dependent device which is illuminated by the display element. The drive transistor is controlled to provide a constant light output from the display element, and the duration is controlled in dependence on the data voltage. Optical feedback is used to alter further the timing of operation of the discharge transistor to provide ageing compensation of the display element and compensation for changes in the drive transistor.
