摘要： A portable electronic device (40) comprises a display module (42) and a battery unit (44). The device has at least one further analogue input or output interface (50,52,54) (in addition to the display). The display module includes a voltage converter (48) for providing at least one voltage exceeding the battery unit voltage, and an output from the voltage converter (48) of the display module is provided to a circuit (50a, 52a, 54a) associated with the at least one further analogue input or output interface. This enables a reduction in cost and volume of the device by providing a highly integrated solution, in which a voltage converter within a display module is used also for circuitry of another interface or interfaces.

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.

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： A display controller (40), comprising: a processor (62) for providing row selection pulses (52, 54, 56) for a display comprising M rows of pixels, the row selection pulses (52, 54, 56) having respective durations (t1, t2, t3 . . . tM) that increase from the pulse (52) for row 1 to the pulse (56) for row M. The processor (62) may retime image data (72) for synchronisation with the increase in the pulse duration, for example by writing incoming data (72) in to a buffer (64) at the rate the incoming data (72) is received and reading the data out from the buffer (64) at a rate corresponding to the increase in the pulse duration. Also described is a display device comprising the display controller (40), and a method of driving the display device using the display controller (40). The increase in row selection pulse duration (t1, t2, t3 . . . tM) is arranged to correspond, with a desired level of precision, to an increasing charging time of the pixels of the rows.

The use of the common electrode in this way assists in avoiding problems due to resistances of connections formed on the first substrate. The connection to a storage capacitor line (37, 36) may benefit especially. The common electrode (26) may be connected to the circuit elements on the first substrate via contact material (92, 100) extending across the gap between the two substrates.

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.
