摘要： A variable color complementary display device includes a plurality of display areas arranged in a pattern for selectively exhibiting a plurality of display units. Each display area includes a plurality of pairs of light emitting diodes for emitting, when forwardly biased, light signals of respective primary colors and a device for combining the light signals in the display area to obtain a light signal of a composite color. Each pair includes a first light emitting diode and a second light emitting diode, both of the same color, connected in an anti-parallel fashion such that their polarities are opposite. A device is provided for selectively forwardly biasing the first light emitting diodes, for illuminating certain of the display areas in a display color. The second light emitting diodes in the remaining display areas are automatically illuminated in a complementary color.

摘要： An active matrix pixel within an active matrix display includes a photodiode that is optically connected to a light emitting diode within the pixel in order to detect a portion of the luminous flux that is generated by the light emitting diode. The photodiode discharges excess charge within the pixel in response to the detected portion of luminous flux. Once the excess charge is discharged, the light emitting diode stops emitting light. In an embodiment, the gate of a drive transistor is controlled by the charge on a storage node. If the charge on the storage node sets a voltage that exceeds the threshold voltage of the drive transistor then the drive transistor conducts. The amount of charge on the storage node above that which is needed to set the threshold voltage is referred to as the excess charge.

摘要： A display apparatus according to our invention comprises a multiplicity of nominally identical smart pixels, a given pixel comprising an organic light emitting diode and an organic or inorganic (e.g., amorphous or polycrystalline Si) pixel FET. The display also comprises drive/compensation circuitry adapted for mitigating or eliminating non-idealities associated with the organic components. Among the non-idealities are variations in mobility and/or threshold voltage of the pixel FET from transistor to transistor, change in mobility and/or threshold voltage with time in a given pixel FET, change over time of the LED characteristics, capacitive signal feed-through through the gate insulator of the pixel FETs by short rise/fall time pulses, poor on-off ratio of the pixel FET, and charge leakage through the gate dielectric. Exemplary drive/compensation circuitry is disclosed.

摘要： A system and method for producing uniform energy dissipation in display pixels with widely varying electrical characteristics in order to equalize light output and improve yield within a matrix addressable display panel. The present invention is implemented within a driver circuit utilizing the concept of current integration. A reference voltage, which is proportional to the most efficient pixel within the display is compared to the energy dissipated within a particular pixel during illumination of that pixel. A current mirror circuit supplies a current equivalent to the current provided to the object pixel to an integrator circuit resulting in a rising voltage within the integrator circuit. The rising voltage is proportional to the energy being dissipated within the current pixel. Once the rising voltage is equal to or greater than the reference voltage, current is removed from the object pixel.

摘要： A driving circuit of display. Two more thin film transistors is added to the original driving circuit of display so that the driving circuit now includes four thin film transistors such that the gate terminal of the thin film transistor's voltage level increases as the threshold voltage of the driving thin film transistor increases. The driving current of the thin film transistor is able to maintain a constant value so that the initial luminance of the display remains unchanged. Therefore, the present invention can effectively increase the average working life of the display.
