AM backplane for AMOLED

چکیده
Active matrix organic light emitting diode (AMOLED) displays are considerably attractive for high brightness, high efficiency and fast response time. Active matrix employing thin Film Transistors (TFTs) allows OLED displays to be larger in size, higher in resolution and lower in power consumption than passive matrix. Especially, low temperature polycrystalline silicon (LTPS) TFT employing excimer laser annealing (ELA) is widely used due to high mobility and high stability. A number of TFT active matrix pixel circuits have been developed in order to compensate for TFT parameter variations due to the fluctuation of excimer laser energy. We discuss various compensation schemes of LTPS TFT pixel circuits.
