We propose a pixel structure and its driving scheme for stereoscopic 3-dimensional (3D) active-matrix organic light emitting diode (AMOLED) displays. The proposed pixel structure and its driving scheme have merits that are longer emission and programming time than simultaneous emission scheme by successive cross emission of left and right images. Moreover, it can reduce flicker by reducing interval between emission times. For 3D AMOLED displays of 40-inch full high definition TV (1920×1080), the emission current error rate of the proposed pixel structure is from -0.961% to 1.013% when the threshold voltage variation of driving TFT varies from -0.8 V to 0.8 V, and that the error is less than 2% when the V DD -IR drop voltage becomes 2.0 V.

A pixel structure for shutter-glasses-type stereoscopic 3-D active-matrix organic light-emitting-diode (AMOLED) displays is proposed. The proposed pixel programs data to the pixel during the light-emission time of an OLED. Because the emission time of the proposed pixel is extended, it is expected that the proposed pixel not only decreases the peak current of the OLED during the emission period but also reduces flicker. Moreover, the aperture ratio of the proposed pixel is 58.69% for a 50-in. full-high-definition (FHD) condition by minimizing the number of thin-film transistors (TFTs), capacitors, and control signal lines as seven TFTs, two capacitors, two power lines, and four control lines per unit pixel. Simulation results show that the error in the emission current of the proposed pixel is from -0.82% to +0.90% when the threshold-voltage variation of the driving TFT is ±1.00 V, and the maximum variation of the emission current is -1.35% when a voltage drop in the power line is -0.50 V on a full-white-image display.
