  • Organic electroluminescence matrix-type single-pixel drivers
    Patent number: 6512334
    Abstract: An organic electroluminescence (OEL) matrix-type single-pixel driver, which comprises: an OEL device, a first transistor, and a second transistor. The first transistor and the second transistor form a complementary structure so that when the data line uses the first transistor to drive an organic light-emitting diode (OLED) device, the second transistor is in the OFF state, causing no power consumption. When the data line is in the LOW state, the first transistor is in the OFF state. The second transistor is in a sub-threshold state after getting rid of extra charges.
    Type: Grant
