Abstract: A holographic display is comprised of space-multiplexed elemental modulators, each of which consists of a surface acoustic wave transducer atop an anisotropic waveguide. Each “line” of the overall display consists of a single anisotropic waveguide across the display's length with multiple surface acoustic wave transducers spaced along the waveguide length, although for larger displays, the waveguide may be divided into segments, each provided with separate illumination. Light that is undiffracted by a specific transducer is available for diffraction by subsequent transducers. Per transducer, guided-mode light is mode-converted to leaky-mode light, which propagates into the substrate away from the viewer before encountering a volume reflection grating and being reflected and steered towards the viewer. The display is transparent and all reflection volume gratings operate in the Bragg regime, thereby creating no dispersion of ambient light.

Abstract: The optical device (100) includes a first substrate (10), a second substrate (20), and an optical layer (30). The first substrate includes a first electrode (11) and a second electrode (12) configured to be provided with mutually different electrical potentials within a pixel. The optical layer may include a medium (31) and a plurality of shape-anisotropic particles (32) dispersed in the medium. At least one of the first electrode and the second electrode may include a plurality of comb teeth portions (11a, 12a) arranged at predetermined intervals along the first direction (D1). When an electric potential difference is applied between the first electrode and the second electrode, the pixel may be configured to have an electrical field distribution in which a strong electric field region having a stronger field intensity than another region is periodically formed parallel to the surface of the optical layer along a second direction (D2) orthogonal to the first direction.

Abstract: Disclosed is a liquid crystal display device having a touch sensor and a method of driving the same, which relates to the technical field of liquid crystal display. The liquid crystal display device having a touch sensor is provided to solve the problem that a penetration rate of a display device in the prior art is decreased significantly. A touch control function is added in a pixel of the liquid crystal display device and the touch control function is achieved through a touch lead. Common electrodes covering data lines between blue sub-pixels and red sub-pixels of two adjacent pixel units are set as touch leads. The touch leads serve as touch lines during a touch scanning stage and serve as the common electrodes during a non-touch scanning stage. Moreover, the present disclosure is mainly applied to a liquid crystal flat display panel.
