21.2: Invited Paper: The application of AMOLED in smart wearable technology

Abstract

Two approaches of fabrication of a 1.2 inch round AMOLED panel were discussed in this paper, in which one is glass+thin film encapsulation(TFE) and the other is polyimide(PI)+TFE. The innovative glass+TFE approach has the distinctive feature of ultra‐thinness compared to traditional glass+glass panel structure, and reduces yield loss in the PI and laser lift off(LLO) process compared to PI+TFE panel. The flexible PI+TFE approach can realize the bending of bottom border. Thus it fulfills true circular requirements for wearable displays.

Simulation Study of Overlap Capacitance in Source-Gated Transistors for Current-Mode Pixel Drivers

“…S display screens continue to progress from a means of delivering information to pervasive entertainment, the competing pressures of improved image quality and low-cost fabrication will increase. Emissive, OLED-based screens show a performance advantage over competing technologies due to their high contrast [1,2], energy efficient [3,4], flexible [5][6][7] and arbitrary-shape [8][9][10] form factor. Significant progress has been made recently in gate driver circuit design [11][12][13][14] and complex pixel circuits, with timing strategies optimized for age compensation or areal uniformity [15][16][17][18][19][20].…”
