大尺寸高分辨率硅基OLED微显示技术研究
Organic Light Emitting Diodes on Silicon Micro-display with High Resolution and Large Size
摘要
开发了一款对角线尺寸超过2.4 cm, 分辨率为1 400×1 050的单色高亮度硅基OLED微显示器件。器件驱动芯片中集成行列驱动、DAC、I2C、数据处理、电源模块、温度检测等功能模块。器件亮度大于35 000 cd/m2, 对比度大于10 000∶1, 器件亮度均一性大于90 %, 在10 000 cd/m2起始亮度下, 器件的T50寿命大于7 500 h。器件性能满足AR显示等需求。
Abstract
A microdisplay of OLED on silicon which has a size of 2.4 cm and resolution of 1 400×1 050 was developed. The display chip integrated the functions of power management、temperature test and DAC. The brightness of device reached 35 000 cd/m2, the contrast ratio was more than 10 000∶1, and the brightness uniformity was more than 90%.The T50 lifetime of the device was tested to be more than 7 500 hours at the 10 000 cd/m2. The performance of device can meet the requirements of AR systems.
