A novel driving scheme based on simultaneous emission is reported for 2D/3D AMOLED TVs. The new method reduces left-right crosstalk without sacrificing luminance. The new scheme greatly simplifies the pixel circuit as the number of transistors for Vth compensation is reduced from 6 to 3. The capacitive load of scan lines is reduced by 48%, enabling very high refresh rate (240 Hz).

3D displays have required 1/240 s of scan time to properly display a stereoscopic image. In this report, a new driving method is proposed that provides 1/120 s of scan time, thus enabling higher resolution. The pixels are arranged as two groups: Even and Odd. One group performs scanning while the other group is emitting and in the next field, these roles are swapped. Therefore, the entire frame time can be used for data input, rather than 1/2 of the frame time as in the previous method.

We have developed a 14.1 inch full color polymer LED display, based on an a-Si TFT backplane, using ink jet printing, which does not show visible swathe marks during display operation. To remove the swathe marks, we have developed the single path printing technology for the hole-conduction layer deposition to significantly reduce the complexity of interlacing printing across the panel, which is known as an alternative to remove the swathe marks. In addition, we have adopted the interlayer process to increase the lifetime of ink jet printed displays. These technologies will enable the scale-up of the ink jet printed AMOLED applications to larger size displays, such as desktop monitors and TVs.

A novel driving scheme, smart power control SPC, is reported to reduce the power consumption of an AMOLED panel. SPC analyzes the range of the input data of each frame, calculates the optimum level of the power rail that drives the OLED, and varies the power rail voltage accordingly. As a result, a 30″ AMOLED consumes 20.1% less power when displaying the IEC 62087 standard movie clip.
