  • Publication number: 20040070557
    Abstract: In an active-matrix display device and a method for driving the active-matrix display device, a fifth transistor is connected between a power line and a drain terminal of a first transistor so that a power-supply voltage, namely the fixed voltage required for the compensation of the threshold voltage, is supplied by the power line via a fifth transistor and not by a signal line. Thus, a sufficient length of time for the threshold voltage compensation period can be maintained, and a second transistor of each pixel can accurately be compensated for threshold voltage irregularities.

  • Publication number: 20030107560
    Abstract: When a current-writing type pixel circuit is made, it involves a greater number of transistors and TFTs occupy much of the area of the pixel circuit. To alleviate this problem, two pixel circuits (P1, P2) have a first scanning TFT (14), a current-voltage conversion TFT (16), respective second scanning TFTs (15-1, 15-2), capacitors (131,13-2), and drive TFTs (12-1, 12-2) for OLED including organic EL elements (11-2, 11-2) of two pixels, for example, in a row direction. In each of the pixel circuits, the first scanning TFT (14) handling a large amount of current (Iw) as compare with current flowing through the OLED (11-2, 11-2), and the current-voltage conversion TFT (16) are shared between two pixels.

  • Publication number: 20030001828
    Abstract: An active matrix type organic EL display apparatus according to the present invention which apparatus uses current writing type pixel circuits is provided with a current control circuit for each of data lines connected to the pixel circuits. The current control circuit supplies part of a data line current to a pixel circuit as a bypass current. The current control circuit handles the bypass current of the data line current represented by (data line current=data current+bypass current). Thereby, the data line driving current can be set greater than the data current flowing through TFTs provided in the pixel circuit, thus reducing luminance data writing time. Also, when the writing time is set unchanged, transistor size of the TFTs provided in the pixel circuit can be reduced.
