摘要： An active matrix display device comprises an array of display pixels provided over a common substrate. Each pixel has a voltage-programmed current source circuit, a drive transistor and a light sensitive device for sensing the display element light output. The light sensitive device provides a current dependent on the display element output, and the light sensitive device and the current source circuit define a feedback control loop which controls the voltage provided to the gate of the drive transistor. This pixel circuit uses a current source circuit to provide a gate voltage to a drive transistor. This enables the current source circuit to operate at low current levels, and therefore under low voltage stress.

摘要： In an active matrix electroluminescent display device, a storage capacitor (24) is provided for storing a voltage to be used for addressing a drive transistor (22). A discharge photodiode (27) is provided for discharging the storage capacitor in dependence on the light output of the display element, and an input data voltage applied to the pixel is changed by an amount corresponding to the threshold voltage of the drive transistor. The changed data voltage is applied between the gate and source of the drive transistor. In this device the initial voltage on the gate of the drive transistor is modified so as to remove the dependency of the light output on the threshold voltage, so that threshold voltage variations can be tolerated.

摘要： Physical barriers (210) are present between neighbouring pixels (200) on a circuit substrate (100) of an active-matrix electroluminescent display device, particularly with LEDs (25) of organic semiconductor materials. The invention forms these barriers (210) with metal or other electrically-conductive material (240), that is insulated (40) from the LEDs but connected to the circuitry within the substrate (100). This conductive barrier material (240) backs-up or replaces at least a part of the drive supply line (140,240) to which the LEDs are connected by a drive element T1. This transfers the problem of line resistance and associated voltage drop from within the circuit substrate (100), where it is severely constrained, to the much freer environment of the pixel barriers (210) on the substrate (100) where the conductive barrier material (240) can provide much lower resistance. Very large displays can be made with low voltage drops along this composite drive supply line (140,240). Furthermore, the structure can be optimised to form a smoothing capacitor (Cs) between this drive supply line (140,240) with its conductive barrier material (240) and the further supply line (230) of the LED upper electrodes (23) extending on an insulating coating (40) over the top of the conductive barrier material (240).

摘要： A method of manufacturing a colour active matrix display device comprises forming islands over a rigid carrier substrate, forming a plastic substrate over the rigid carrier substrate, forming an array of pixel circuits over the plastic substrate and forming a display layer over the array of pixel circuits. The rigid carrier substrate is then released from the plastic substrate and the plastic substrate then has channels defined by the islands. These are filled to define colour filter portions. The formation of a plastic substrate on a rigid carrier, with the use of a subsequent lift off process, enables the circuit arrays to be made on very thin plastic sheets. The colour filters can then be made on the outside of the LC cell. Depressions are formed in the plastic substrate registered to the circuit array, and these are filled in with colour filter material, for example by ink jet printing.

摘要： An active matrix EL display has first and second capacitors connected in series between the gate and source or drain of a pixel drive transistor. A data input to the pixel is provided to the junction between the first and second capacitors thereby to charge the second capacitor to a voltage derived from the pixel data voltage, and a voltage derived from the drive transistor threshold voltage being stored on the first capacitor. A discharge transistor is connected between the junction between the first and second capacitors and a common line for all pixels of the display. This device uses a common line as a discharge sink/source for the threshold voltage measurement operation. By avoiding the use of a data line for this purpose, the pixel can be in a non-addressed state when the threshold measurement takes place.

摘要： An electroluminescent (EL) display device has current-driven pixels and is operable in at least two phases within each frame period. In one phase, one of a first plurality (31) of analogue drive currents can be driven through EL display element. In another longer phase, one of a second plurality (33) of analogue drive currents is independently driven through the EL display element. This device combines a time ratio method with an analogue drive scheme. A shorter phase may provide the higher resolution (smaller) increments and one longer phase may provide lower resolution (larger) increments. Low brightness outputs can be achieved with a higher drive current, but over a short duration, which reduces non-uniformity in the pixel output.

摘要： Each pixel of an active matrix display has a current driven light emitting display element (2), a drive transistor (22; T D ) for driving a current through the display element from a power supply line (26) and a storage capacitor (24) connected between a data input to the pixel and the gate of the drive transistor. A discharge transistor (34) is connected between the gate and drain of the drive transistor and a coupling transistor (36) is connected between the data input to the pixel and the power supply line. The pixel is operable to store a voltage on the storage capacitor which is dependent both on an input voltage supplied to the data input and on the drive transistor threshold voltage. This arrangement enables a single capacitor to store a voltage derived both from the data input and the threshold voltage, and without needing to provide a complicated waveform to the data conductor.

摘要： The pixels of an active matrix display device have a current-driven light emitting display element, a drive transistor for driving a current through the display element, a storage capacitor for storing a pixel drive voltage to be used for addressing the drive transistor, a light-dependent device for detecting the brightness of the display element, and driver circuitry for providing data signals to the pixel external to the pixel array. This provides a pixel with optical feedback to compensate for display element ageing. The driver circuitry has a processing means for processing the feedback brightness signals and derives from them a threshold voltage for the drive transistor of the pixel as well as information relating to the performance of the display element, for ageing compensation.
