  • STEREOSCOPIC DISPLAY DEVICE HAVING A BARRIER PANEL
    Publication number: 20200244947
    Abstract: A stereoscopic display device having a barrier panel is provided. The barrier panel may include channel electrodes across an active area. Each of the channel electrodes may include an end portion connected to corresponding link line. Each of the channel electrodes may be connected to the link line same as (n+1)th channel electrode from the channel electrode. The barrier panel may further include connecting lines to connect between opposite end portions of the channel electrode which are connected to the same link line. Thus, in the stereoscopic display device, the number of the wires extending along an edge of the active area may be reduced.

  • STEREOSCOPIC DISPLAY DEVICE HAVING A BARRIER PANEL
    Publication number: 20200233231
    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.

  • AEROGEL PARTICLES AND METHOD OF MAKING THE SAME
    Publication number: 20200172696
    Abstract: Aerogel particles and a method of making the same are revealed. The method includes the steps of (a) adding a siloxane compound containing methyl groups and a surfactant into water, mixing well and carrying out hydrolysis to get a mixed aqueous solution; (b) mixing the mixed aqueous solution with 0.1-0.2M ammonium hydroxide and a remaining percentage of an organic solvent, and stirring the mixture under nitrogen atmosphere for emulsion polymerization to get a water-in-oil (w/o) lotion; and (c) removing the organic solvent and drying the w/o lotion to get aerogel particles. Thereby the aerogel particles are produced by the present method without hydrophobic treatment and solvent exchange. Therefore the cost and time used for preparing the aerogel particles are saved.
