Abstract

We proposed a DEMUX (De‐multiple) technology based on IGZO BCE‐type TFT structure and produced the 13.3 inches FHD LCDs for notebook. The adoption of DEMUX 1:3 circuit on panels combing with TED (Tcon‐Embedded Driver) technology realized a narrow module bezel of less than 15mm for the LCDs. A slight horizontal streaks issue observed on RG/GB/RB mixed color image under middle and low grayscale display is analyzed and discussed. The modeling and simulation results indicate that the issue is related to the drive architecture of Zigzag‐column inversion under charging insufficient of source lines.
