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 LED displays due to the finite output impedance of the current providing TFTs as well as the finite resistance of metals used to form power supply lines.

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： Each stage of a shift register circuit has an input section (60) and an output section (62). The input section of each stage comprises an input section drive transistor (Tdrive) for coupling a first clocked power line voltage (Pn) to the output of the input section (60), an input section compensation capacitor (Ci) for compensating for the effects of a parasitic capacitance of the input section drive transistor (Tdrive) and a first input section bootstrap capacitor (C2) connected between the gate of the drive transistor and the output of the input section. The input section (60) of each stage uses the output (Rn-i) of the input section (60) of at least one preceding stage as a timing control input for controlling a bootstrap function, and the output section (62) of each stage comprises a circuit which receives the outputs of multiple input sections (60) as timing signals for generating output signals for the output loads (64). This circuit uses one stage to provide the required timing signals, and has feedback of timing signals between stages. This stage has low output load, and can therefore be realized with low size components, and the timing signal retain their shape even when there is degradation of the component characteristics. The other stage drives the load, and the output signals are not used as feedback timing signals, so that the output load does not degrade the timing control signals used in other stages.

摘要： A method of driving an active matrix display device comprises, for each pixel, driving a current through a drive transistor (22) by applying a gate voltage to the drive transistor which comprises a fixed component and a component which depends on a measurement of the threshold voltage of the drive transistor (22), and switching off the drive transistor using a discharge transistor (36) for discharging a capacitance between the gate and source of the drive transistor (22), and at a time which depends on the optical output of the display element (2) and a pixel data signal. This method uses optical feedback to implement a duty cycle control for the output of the display element. The brightness of the display element when turned on is determined by the drive transistor drive voltage, and this takes account of the threshold voltage. Although the optical feedback system enables compensation of the threshold voltage, by providing compensation initially in this way, the lifetime for correct functioning of the optical feedback system can be extended. The time at which the drive transistor is switched off can also depend on a measured threshold voltage of the discharge transistor.

摘要： Each stage of a shift register circuit has a first input (R n-1 ) connected to the output of the preceding stage, a drive transistor ( T drive) for coupling a first clocked power line voltage (P n ) to the output (R n ) of the stage, a compensation capacitor (C 1 ) for compensating for the effects of a parasitic capacitance of the drive transistor, a first bootstrap capacitor (C 2 ) connected between the gate of the drive transistor and the output (R n ) of the stage; and an input transistor (T in1 ) for charging the first bootstrap capacitor (C 2 ) and controlled by the first input (R n-1 ). Each stage has an input section (10) coupled to the output (R n-2 ) of the stage two stages before the stage having a second bootstrap capacitor (C 3 ) connected between the gate of the input transistor (T in1 ) and the first input (R n-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： A system for driving a moving particle display device, such as an electrophoretic display device, is disclosed. The display device comprises first and second cells (30) that are set to target optical states to give the cells' their target optical appearances. The first and second cells are driven differently from one another, such that errors in the first cell's target optical state occur in the opposite direction to errors in the second cell's target optical state. Hence, when the cells are viewed from a distance by a viewer of the display, the light from the first and second cells mixes together, and the optical state errors appear to compensate or cancel one another out.

摘要： A thin film circuit comprises a plurality of thin film transistors, each having a light shield portion (60) which is electrically isolated from the source (72), drain (70) and gate (76) electrodes. The light shield portion comprises a first, drain overlap portion in which the light shield portion overlaps the drain conductor (70), a second, source overlap portion in which the light shield portion overlaps the source conductor (72), and a third, gate overlap portion in which the light shield portion overlaps the gate conductor (76) only. In one embodiment, at least 2/3 of the light shield portion area comprises the gate overlap portion. In another embodiment, one of the source and drain overlap portions has at least 1.5 times the area of the other of the source and drain overlap portions. The use of an electrically floating light shield simplifies the layer construction and design. The arrangement of overlap areas provides controlled capacitive coupling between the light shield and the transistor terminals, and this can suppress the effect of the light shield voltage floating to levels which impact on circuit performance.
