Breaking the limits of virtual reality display resolution: the advancements of a 2117-pixels per inch 4K virtual reality liquid crystal display
This work presents a breakthrough in the development of high-resolution virtual reality (VR) displays of 2117-pixels per inch (PPI) liquid crystal displays (LCDs). This technology significantly improves the dynamic range and reduces the screen door effect in VR displays. The challenges and potential solutions for achieving over 2000-PPI LCDs, including the design of the aperture ratio of pixels, improvements in LC efficiency, and overall transmittance, are discussed. Moreover, the use of mini-light-emitting diode backlight and low-power solutions to maintain the image quality in high-resolution designs are also proposed.
