We propose a novel n-type a-Si:H TFT pixel circuit which is proper to AMOLED display for the large size and high resolution. Proposed pixel circuit will be suit to panel for the high resolution because of different threshold sampling method. Driving method of proposed pixel circuit is very simple like an AMLCD. Our simulation indicates that the proposed pixel circuit can compensate the Vth shift and IR rising of power line so that provide better quality image.

Active-matrix electrophoretic display (AMEPD) is commonly used for the applications of smart handheld reading devices such as e-books and e-news. This paper presents a new reduced waveform lookup table storage method that reduces the associated lookup table by approximately 2n (n is the number of gray levels employed) times the conventional one. The paper also proposes a driving method for image display. The method provides high-speed performance for image display and also effectively eliminates the image residue, achieving high image quality. The prototyped controller was connected to a 6" AMEPD panel, whose excellent display quality demonstrated the effectiveness of the proposed controller design.

We have developed a 2D-3D convertible 7" autostereoscopic mini-monitor with high 3D quality, in which the parallax barrier LCD is attached on the TFTLCD. The excellent optical performance was achieved by design of the ghost free barrier and precise assembly between the barrier layer and the TFT-LCD panel. Our design principle and fabrication technology suppressed 3D cross-talk and improved viewing angle. In this paper, the design and fabrication process of the 3D mini-monitor are described. The evaluation for the 3D performance is also discussed.

The life time of AMOLED displays has been dependent on OLED materials up to this point. In particular, image sticking (burn-in) has been one of the most critical issues for AMOLEDs. This paper proposes image sticking compensation AMOLED pixel circuits to address the problem without requiring process or material improvements to the OLED itself. We verified the performance of those circuits by simulation and actual panel implementation.

A single-clock-driven shift register and a two-stage buffer are proposed, using p-type, low-temperature polycrystalline silicon thin-film transistors. To eliminate the clock skew problems and to reduce the burden of the interface, only one clock signal was adopted to the shift register circuit, without additional reference voltages. A two-stage, p-type buffer was proposed to drive the gate line load and shows a full-swing output without threshold voltage loss. The shift register and buffer were designed for the 3.31" WVGA ($800{\times}480$) LCD panel, and the fabricated circuits were verified via simulations and measurements.

We developed new anti-glare(AG) layer which has improved image quality and solved mechanical problems. Conventional silica-type AG has some restrictions related to sparkling, causing mechanical defects. The new anti-glare layer is designed with adjusted optical factors and polymer type. Therefore new anti-glare layer meets two main characteristics at once using unmatched optical property between scattering in material and surrounding.
