DISPLAY UNIT, DRIVE CIRCUIT, AMORPHOUS SILICON THIN-FILM TRANSISTOR, AND METHOD OF DRIVING OLED
摘要:
A display unit has an organic light emitting diode (OLED) 21 provided in correspondence with each of pixels and capable of emitting light by itself a drive transistor 22 for driving the OLED 21, a twig transistor 23 which is formed so as to have a portion of an electrode of the drive transistor 22 independently formed, and which is used to detect a threshold voltage (Vth) of the drive transistor 22, a compensating capacitor 28 in which the threshold voltage (Vth) detected by the twig transistor 23 is written, a signal capacitor 27 in which a signal voltage to be supplied to the drive transistor 22 is written, a first transistor 24 provided between a data line and the signal capacitor 27, a second transistor 25 provided between the signal capacitor 27 and the compensating capacitor 28, and a third transistor 26 provided between a gate electrode and another electrode of the twig transistor 23.
