    ABSTRACT


    The Design, Fabrication Method and Characterization of Parallax Barrier Type High Performance 3-Dimension Display

    Recently, 3D displays have been familiar with people through 3D cinema and 3D TV. These 3D displays need polarizing or shutter glasses, which makes people feel uncomfortable. As an non-glasses type 3D displays, so called ‘autostereoscopic 3D displays’ parallax barrier type 3D displays have been developed.
    The parallax barrier type 3D displays have been commercialized for various applications, for a representative example, mobile application. There are key technical issues for the parallax barrier type mobile 3D displays: the reduction of thickness and weight, and pivot function enable for us to see 3D image both for landscape and portrait modes as well as widening 3D viewing angle.
    In this paper, the methods to achieve the reduction of thickness & weight and pivot function for the parallax barrier type 3D displays were investigated. In addition, the manufacturing technologies for achieving high quality 3D displays and the application to dual-view displays using the parallax barrier technology were discussed.
    As a way to reduce the thickness and weight, TSP (Touch Screen Panel) integrated parallax barrier LCD was developed. To realize 3D pivot function, two kinds of electrode patterns were made on substrates: for example, horizontal stripe electrode pattern on upper substrate and verticall stripe electrode pattern on lower substrate. The aims to achieve the thickness and weight reduction and the pivot function were successfully realized through the fabrication of prototypes samples: the driving voltage lower than 5V, the 3D cross-talk lower than 10%, 3D viewing angle of more than 5 degrees, 3D viewing distance in between 300 and 400mm.
    For the manufacturing of high-quality 3D displays, a precise align technology and OCR process technology were developed. By applying the technology, 3D luminance was improved by 1.4% and the overall luminance of the black level was decreased.
    The application of a parallax barrier method to a dual-view display was studied. Through the prototype sample fabricated by applying the same process as parallax barrier formation process, clear dual-view images were verified.
