  • Patent number: 11973924
    Abstract: A barrier panel includes a first substrate and a second substrate having block region and transmission region; a liquid crystal layer between the first and second substrates, the liquid crystal layer including a plurality of liquid crystal molecules aligned in a predetermined direction; a plurality of barrier electrodes in the block region and the transmission region of the first substrate; a common electrode on the second substrate to apply an electric field to the liquid crystal layer with the plurality of barrier electrodes; a diffraction unit in the plurality of barrier electrodes to diffract the light transmitting therethrough; and a polarization plate over the second substrate, wherein an optical axis direction of the polarization plate is parallel to the alignment direction of the liquid crystal molecule to transmit an image through an area where the electric field is not applied.

  • Publication number: 20240125991
    Abstract: Disclosed is a transmissive wavelength tunable hyperspectral filter using layered twisted liquid crystal thin film, wherein the transmissive wavelength tunable hyperspectral filter is formed by laminating two or more layered twisted liquid crystal thin films having different broadband reflection bandgaps, wherein each of the layered twisted liquid crystal thin films includes a twisted liquid crystal layer including a plurality of unit liquid crystal molecules, and formed by arranging twisted liquid crystal complexes defining a preset cone angle along the helical axis with respect to the helical axis, and includes a pseudo-layer formed by arranging a plurality of twisted liquid crystal layers in a lengthwise direction of the helical axis at a preset inter-layer pitch (P).

  • Patent number: 11924399
    Abstract: A stereoscopic display device including a barrier panel is provided. When a viewing distance of a viewer is out of the proper range, the stereoscopic display device may shift the blocking regions and the transmitting regions of the barrier panel. The stereoscopic display device may maintain the ratio of channels located within a barrier blocking region and a barrier transmitting region of the barrier panel by using the channels disposed within trigger regions of the barrier panel. Thus, the stereoscopic display device may provide a stereoscopic image of good quality to the viewer located at a region being out of the proper range.

  • Publication number: 20050066074
    Abstract: A communication device and method is provided, comprising: a signal modulator/demodulator having a digital signal processor for effecting radio communications; and an application processor (AP) having a central processing unit and a master controller for controlling via a common bus a plurality of peripherals including an interface with the signal modulator/demodulator, wherein a memory shared by the modem and the AP is controlled via the interface. The plurality of peripherals include at least one of an image capture module, a display, and a flash memory. The master controller controls the plurality of peripherals by issuing a packetized command commonly receivable by the plurality of peripherals over the common bus, the packetized command includes a module device select signal used for selecting one of the peripherals.
