  • Patent number: 11994687
    Abstract: A display system includes an optical device configured according to constructive interference for a plurality of wavelengths at a focal length. The display system includes a fiber. The display system includes a controller configured to scan the fiber using a Lissajous scanning method to generate a display. The display can be disposed within a focal plane of the optical device. The controller is configured to modulate light intensity from the fiber. The controller can be configured to form a display image that passes through the optical device. The display system can include an optical combiner configured to reflect the display image from the optical device and form a virtual image. The optical device can be configured to magnify a display image from the display and form a virtual image.

  • Patent number: 8274618
    Abstract: A pixel structure and a pixel array including the same are provided. The pixel structure includes a scan line, a capacitor electrode, a data line, an active device, and a pixel electrode. The capacitor electrode is electrically independent from the scan line and includes a first portion and at least one second portion. The first portion and the second portion extend in different directions, and an extending direction of the first portion is substantially the same as an extending direction of the scan line. The data line and the scan line are intersected with each other and electrically independent from each other. The data line is overlapped with the second portion of the capacitor electrode. The active device is electrically connected to the scan line and the data line. The pixel electrode is electrically connected to the active device and covers the data line and the capacitor electrode.

  • Publication number: 20120120330
    Abstract: A stereoscopic display device includes a reactive mesogen layer disposed inside the stereoscopic display, such that a backlight source has a first polarization state and a second polarization state after passing the reactive mesogen layer. The manufacturing method includes the following steps. First, a liquid crystal layer and a reactive mesogen layer are formed between a first substrate and a second substrate, wherein the first substrate includes at least one first eye image region and a second eye image region. Then, render the liquid crystal layer corresponding to the first eye image region and the second eye image region a first state and a second state, respectively. A first exposure step is performed on the reactive mesogen layer for emitting a first exposure light source passing the liquid crystal layer to induce photopolymerization reactions in the reactive mesogen layer. Subsequently, a backlight source is provided.
