Abstract: 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.

Abstract: An improved portable personal computer preferably configured to facilitate outdoor field-use has an impact attenuating case, a sealed keyboard, and a sealed mouse which facilitate use of the computer in harsh environments. The case has a impact attenuating covering in which is housed a hard drive on a shock-isolated mount and a display further mounted in die case in a resilient shock-isolated manner. The case, hard drive mount, and display mount cooperate to attenuate shock-induced damage resulting from impacts and sudden accelerations of the computer caused during rugged use. Furthermore, the sealed keyboard and mouse assemblies prevent any damage which might result from liquids migrating within the case and into the computer components.
