40.2: Invited Paper: LTPS and AMOLED Technologies for Mobile Displays

Abstract

In this paper, significant progresses on low‐temperature poly‐Si (LTPS) backplane technologies as well as active‐matrix organic light emitting diode (AMOLED) architectures were demonstrated and reported. In order to make display more compact, reliable and further reduction in the cost, system‐on‐panel (SOP) was realized with good device performance and small design rule capability. Moreover, over the past few years, many hypes on AMOLED have been announced, but less achievement was done for production activity. To overcome these technical challenges such as non‐uniformity, power consumption and higher resolution issues, several approaches are proposed for AMOLED displays

P‐198L: Late‐News Poster: Integrated Ambient Light Sensor in LTPS AMLCDs

“…There is interest in integrating the sensor in the same LTPS technology used to fabricate the display so that the overall complexity of the module is reduced [1][2][3].…”

Digital time‐modulation pixel memory circuit in LTPS technology

“…For these features, LTPS thin-film transistors (TFTs) are utilized in system-on-panel (SOP) applications, where some peripheral functional circuits are integrated on the panel, such as driver circuits, a digital-to-analog converter, a timing controller, a DC-DC converter, and interface circuits. [1][2][3] The trends in mobile system-on-panel (SOP) liquid-crystal displays (LCDs) was reported in Ref. 3, where broadband services are in great demand as wireless transmission speed is increasing.…”

Design and implementation of readout circuit on glass substrate with digital correction for touch‐panel applications

“…Furthermore, the operating voltage and device dimensions should decrease, resulting in low power consumption along with the integration of peripheral functional circuits on the panel. [1][2][3][4] Broadband services will be in great demand as wireless transmission speed increases. As a result, the features of using LTPS technology encourage the further spread of SOP applications.…”
