We have successfully fabricated amplified intrinsic fringe field AIFF MVA LCDs for both smart phone and TV applications. We achieved a transmission of 4.2% in a 70% NTSC color 3.8‐in WVGA panel with 246 pixel per in using a standard 5‐mask TFT process. Using a 6‐mask process improved the transmission to 4.9%. These pixel designs may be used for full HD 1920×1080 tablet PCs displays. We transformed a 26‐in WXGA LC TV from TN mode to AIFF MVA mode using only one mask change from the TN masks. The measured transmission between 5.1 and 5.5% is greater than all published MVA and IPS LC TV displays. The AIFF MVA LCD design eliminates the need for any protrusions or ITO slits in both TFT and ITO substrates, as well as the need for special driving schemes and materials. The AIFF MVA is therefore a low‐cost, high transmission, high contrast‐ratio, and wide viewing‐angle solution for both small‐medium and large size LCD applications.
