摘要： A pixel (142) includes an organic light emitting diode (OLED), a first driver (146) and a second driver (148). The second driver (148) controls an amount of current supplied from a first power source (ELVDD) to the organic light emitting diode (OLED), corresponding to a previous data signal. The first driver (146) stores a current data signal supplied from a data line (Dm) and supplies the previous data signal to the second driver (148). In the pixel (142), the second driver (148) includes a sixth transistor (M6) coupled between an initialization power source (Vinit) and a first node (N1) coupled to a gate electrode of a first transistor (M1), the sixth transistor (M6) being configured to turn on when a first control signal is supplied to a first control line (Cl1); and a seventh transistor (M7) coupled between the first power source (ELVDD) and a second node (N2) commonly coupled to the first and second drivers (146, 148), the seventh transistor (M7) being configured to turn on when the first control signal is supplied.

摘要： A plurality of first and second sensor pixel circuits each sensing light during a designated sensing period and retaining the amount of sensed light otherwise are arranged in a pixel region. A backlight is turned on once for a predetermined time in one-frame period. A sensing period A1 when the backlight is turned on and a sensing period A2 when the backlight is turned off are set once, respectively, in the one-frame period. The first sensor pixel circuit is reset at the start of the period A1 and senses light in the period A1. The second sensor pixel circuit is reset at the start of the period A2 and senses light in the period A2. Read from sensor pixel circuits of two types is performed in parallel in a line sequential manner during a period other than the periods Al and A2. A difference circuit provided outside of the sensor pixel circuits is used for obtaining a difference between an amount of light when the backlight is turned on and an amount of light when the backlight is turned off. Thus, there is provided a display device having an input function which does not depend on light environments.

摘要： An illuminating device is provided with a plurality of light source modules (LM) each of which has a light emitting element and a driver circuit for driving the light emitting element, and the illuminating device controls the driver circuit of each light source module individually. All the light source modules are grouped by having a plurality of light source modules arranged at intervals (d) as one group. A step of lighting light emitting bodies of the light source modules in the same group (for instance, LM (1, 1) · LM (1, 9)) simultaneously under predetermined conditions is performed in turn for all the groups. Based on the obtained light emitting quantity of the light emitting element of each light source module (LM), the driver circuit of the light source module is controlled. Thus, in a backlight device provided with a plurality of illuminating areas, the light emitting quantity in each illuminating area can be accurately corrected in a short time.

摘要： An active matrix display device has an array of display pixels, each pixel comprising a current-driven light emitting display element (2), a drive transistor (22) for driving a current through the display element and pixel circuitry including an optical feedback element (38), for controlling the drive transistor to drive a substantially constant current through the display element for a duration which depends on the desired display pixel output level and an optical feedback signal of the optical feedback element. An output configuration is applied to the display which includes values for the pixel power supply voltages, the field period and an allowed range of pixel drive levels. The output configuration is varied in response to ageing of the display element. In this device, an output configuration is varied as the device ages, so that the optical feedback system can continue to provide compensation for differential ageing of the display elements for a longer period of use of the display.

摘要： An active matrix electroluminescent display device has power supply lines (26) in the column direction. An isolating transistor (30) is provided for isolating a drive transistor (22) of each pixel from the pixel display element (2). The device is operable in two modes. In a first mode, the isolating transistor (30) isolates the drive transistor (22) from the display element (2) for each pixel, and pixel drive signals are provided to all pixels of the array in a row-by-row sequence. In a second mode, the isolating transistor couples the drive transistor to the display element and current is driven through the display elements. In this display device, pixel drive signals are loaded into the display array in one phase, in a row by row manner. As the power supply lines are in columns, during loading of the pixel drive signals, a current is provided to only one pixel along the power supply line at a time. No current is drawn by any display elements during this time, so that vertical cross talk is avoided. This enables pixel data to be stored accurately on the pixels.

摘要： An active matrix LED display device uses optical feedback for controlling the pixel drive transistors (2). The LED display elements are controlled to provide a pulsed output, and the optical feedback element (66,68) is controlled cyclically such that, for constant illumination of the optical feedback element (66,68) during a cycle, there is a substantially zero net output charge flow. This arrangement uses pulsed light output, and arranges the optical feedback to operate only in response to a corresponding pulsed light input. In this way, ambient light, which will be uniform over the time period of the cycle of operation, will not influence the optical feedback system. In this way, the system is not influenced by ambient light conditions.

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.
