Abstract

This study developed an organic light-emitting diode display featuring c-axis-aligned crystalline oxide semiconductor (CAAC-OS) field-effect transistors (FETs) monolithically stacked over silicon (Si) FETs. This display achieved a definition of 5,009 ppi and a luminance of 10,000 cd/m². Below the display pixels incorporating CAAC-OS FETs, both source and scan drivers and a central processing unit (CPU; Cortex-M0) were integrated using Si FETs without widening the bezel. The findings indicate that the built-in CPU enables amplifier offset compensation, which is necessary for image quality correction, and that functional circuits beyond the display driver can operate on a Si substrate.

5009-ppi, 10000-cd/m2， OLED/OS/Si结构显示屏，内置CPU和显示驱动

本研究开发了一种有机发光二极管显示器，其特征是c轴排列的晶体氧化物半导体（CAAC-OS）场效应晶体管（fet）单片堆叠在硅（Si）场效应晶体管上。该显示器实现了5009ppi的清晰度和10000 cd/m2的亮度。在包含CAAC-OS fet的显示像素下方，源和扫描驱动程序以及中央处理单元(CPU；Cortex-M0)采用Si fet集成而不加宽边框。研究结果表明，内置CPU可以实现放大器偏移补偿，这是图像质量校正所必需的，并且显示驱动器以外的功能电路可以在Si衬底上运行。

期刊介绍： The Journal of the Society for Information Display publishes original works dealing with the theory and practice of information display. Coverage includes materials, devices and systems; the underlying chemistry, physics, physiology and psychology; measurement techniques, manufacturing technologies; and all aspects of the interaction between equipment and its users. Review articles are also published in all of these areas. Occasional special issues or sections consist of collections of papers on specific topical areas or collections of full length papers based in part on oral or poster presentations given at SID sponsored conferences.
