Design of Current Programmed Amorphous Silicon AMOLED Pixel C
The present work describes in detail the design of currentprogrammed amorphous Silicon (a-Si:H) Active matrix organic light emitting diode (AMOLED) pixel circuits. The central design principle in these circuits is described and tradeoffs between TFT sizes and supply voltage elaborated. It is shown that drive currents as high as 20μA can be achieved with very good linearity.

A pixel design for active matrix organic light emitting diode (AM-OLED) displays employing hydrogenated amorphous silicon (a-Si:H) thin film transistors (TFTs) is proposed. The proposed pixel circuit, which composed of five TFTs and one capacitor, could compensate the shift of threshold voltage of OLED as well as the threshold voltage of a-Si:H. We fabricated the pixel circuits on the glass sub...
متن کاملAM backplane for AMOLED
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 excim...
متن کاملHigh Resolution AMOLED Pixel Using Negative Feedback Structure for Improving Image Quality
Abstract An active matrix organic light emitting diode (AMOLED) pixel structure is proposed to improve image quality of high resolution small sized displays. The proposed pixel structure increases luminance uniformity by decreasing the distortion of the voltage in the storage capacitors using negative feedback structure. The simulation results show that the distortion of the voltage in the stor...
