Different display-based technologies like LCD, OLED and LED, all meet barriers in increasing brightness and pixel density. In this paper, a defect-free high-contrast fast (~100) active-matrix addressed DHFLC is proposed with a theoretical 11500 PPI due to its nature of no fringe field effect (FFE) and high capacitance, shedding a light on the barriers. For the realization, the no-storage-capacitor AM-DHFLC display device is fabricated as a preliminary demo with both optimizations in the DHFLC alignment and pixel design. Innovatively, the no-storage-capacitor characteristic, which is impossible for NLC, not only rockets efficiency and aperture ratio from 57% to 83% with high brightness, but also reveals the potential in reducing the pixel size for higher resolution. Moreover, the fast response around 100 at 360 Hz for FSC display and no-FFE strengthen the promising potential of DHFLC in various modern display technologies, be it VR/AR, high PPI display, microdisplay, and high-resolution hologram.
