Abstract

一种适用于显示技术领域的OLED拼接显示屏，包括OLED前板(1)及单体结构的TFT驱动背板(2)，在OLED前板(1)之出光侧还设有封装基板(3)。OLED前板(1)包括多块相互拼接的OLED前板单元(11)。OLED前板单元(11)通过导电胶膜与TFT驱动背板(2)对接。通过在TFT背板(2)上拼接OLED前板单元(11)，提高了显示屏的生产效率及良品率，降低了成本。拼接OLED前板(1)减小了拼接缝隙，可实现无缝拼接。与传统的采用光学透镜来消除拼接缝隙的结构相比，提高了拼接显示屏的良品率。使用导电胶膜对接OLED前板(1)与TFT驱动背板(2)，提高了显示开口率。并且该显示屏克服了对位精度难以控制及稳定性差的问题。
