¼ Wave Retarder

Structure of the Data Image display is pasting a layer of polarizer and a layer of glass with a thickness of 1/4 wave length on top of the surface of panel. At the glass back of the panel is pasted another layer of glass with the thickness at 1/4 wave length to change the input light into polarized light after passing through the polarizer. The next layer of glass plate then changes the phase of the polarized light. Then is reflected by the glass at bottom of panel and absorbed by the polarizer layer after passing through the glass layer on the panel surface. This reduces the reflectivity of outdoor light and displays the clear image on the LCD screen with this specialized panel.
