Abstract
In order to achieve the increasingly frivolous mobile terminal requirements,In-cell Touch technology is the best choice for touch control.At present,the Amorphous Indium Gallium Zinc Oxide Thin Film Transistor (a-IGZO TFT) has attracted more and more attention.Compared with the traditional silicon-based TFT,IGZO have their respective advantages,for example,the manufacturing cost is lower compared to LTPS TFT,and the process is easy to control.This paper introduced the design of 5.5 in FHD In-cell panel based on IGZO technology.The IGZO-TFT model is used to design the multiplexer (MUX) for the first time and drive the panel described in this paper.The SNR value of the final prototype is optimized to reach 54 dB.At the end,the paper shows the demo of this design.We briefly introduced the key structure of self-capacitance multiple in-cell touch.We analyzed the problems caused by parasitic capacitance in the producing,and described the solution of them.With integration of the IGZO technology and In-cell Touch technology,we can get a high specification touch panel in a relatively simple process.关键词
