Patent number: 11419223Abstract: A touch display module has plural sensors and includes an integrated frame, a backlight module, a thin film transistor substrate, a color filter, and a polarizer. The integrated frame has a bottom plate portion and a side plate portion, and the side plate portion stands on the bottom plate portion. The backlight module is disposed on the bottom plate portion. The thin film transistor substrate is disposed on the backlight module. The color filter is disposed on the thin film transistor substrate. The polarizer is disposed on the color filter. One surface of the polarizer is an outer surface of the touch display module. The thin film transistor substrate and/or the color filter is connected to the side plate portion of the integrated frame. Therefore, by using the integrated frame to integrate required components into one mechanical part, the touch display module has thinner thickness and lighter weight.Type: GrantFiled: October 23, 2020Date of Patent: August 16, 2022Assignee: TPK Touch Systems (Xiamen) Inc.Inventors: Yan Jun Xie, Qing Wen Hong, Jun Ping Yang, Qi Jun Zheng, Jun Jie Zheng, Ming Chuan Lin, Kuo Hsin Wang, Sheh Jung Lai, Yu Ling Chen
