20090015761 | Combination transparent touch panel liquid crystal display stack and methods of manufacturing same - A method of manufacturing an integrated transparent touch panel liquid crystal display device. A liquid crystal display component is made by forming a polarizing film an on underside and a quarter wave plate on an upper side, with the top polarizer removed. A transparent touch panel component is made by forming a pair of facing transparent electrodes on respective transparent substrates. A quarter wave plate is formed above the upper substrate, along with a second polarizer and antireflective layer in that order. The transparent touch panel is placed above the liquid crystal display component to form an integrated device. Improved daylight readability is achieved without increasing luminance or power consumption. | 01-15-2009 |
