Briefly, an intelligent label is disclosed that has two viewable surfaces. Each surface is constructed such that a permanent and irreversible message may be set into each surface independently. That is, a first message may be set into the first viewing surface of the electro-optic material, and another message may be set into the second viewing surface, for example, at a later time. Various constructions are described including a construction using two pairs of stimulating electrodes, and a second construction using a single pair of stimulating electrodes.

The display panel includes a first substrate, a second substrate, pixel structures, a liquid crystal layer and a transparent conductive layer. The liquid crystal layer is disposed between the pixel structures and the second substrate. The transparent conductive layer is disposed between the second substrate and the liquid crystal layer. When a liquid crystal molecule of the liquid crystal layer is a positive liquid crystal molecule, an absolute voltage difference between the transparent conductive layer and the common electrode is smaller than or equal to 2.3 volts(V). When the liquid crystal molecule of the liquid crystal layer is a negative liquid crystal molecule, the absolute voltage difference between the transparent conductive layer and the common electrode is smaller than or equal to 5V.

An array substrate is disclosed. The array substrate includes a semiconductor active layer, a gate insulation layer, a first metal layer, an interlayer dielectric layer, a second metal layer, a planarization layer and a passivation layer sequentially disposed on a base substrate; wherein the array substrate is provided with a row driving unit, including a capacitor structure; wherein the capacitor structure includes a first capacitive plate formed in the semiconductor active layer, a second capacitive plate formed in the first metal layer and a third capacitive plate formed in the second metal layer; and wherein projections of the first capacitive plate and the second capacitive plate on the base substrate are partially overlapped, projections the second capacitive plate and the third capacitive plate on the base substrate are partially overlapped and the third capacitive plate is electrically connected to the first capacitive plate through a first via hole.

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.

The present disclosure is in the field of an electrophoretic device for switching between a transparent and non-transparent mode, comprising a fluid and particles, electrodes for moving said particles, and comprising various further elements, as well as uses thereof, in particular as a window blind.
