Bright ambient light can wash out a virtual image in a conventional augmented reality device. Fortunately, this problem can be prevented with a variable electro-active beam splitter whose reflect/transmit ratio can be varied or switched on and off rapidly at a duty cycle based on the ambient level. As the ambient light gets brighter, the beam splitter's transmit/reflect ratio can be shifted so that the beam splitter reflects more light from the display and transmits less ambient light to the user's eye. The beam splitter can also be switched between a highly reflective state and a highly transmissive state at a duty cycle selected so that the eye spends more time integrating reflected display light than integrating transmitted ambient light. The splitting ratio and/or duty cycle can be adjusted as the ambient light level changes to provide the optimum experience for the user.

The present invention relates to a pressure-sensitive adhesive composition. The pressure-sensitive adhesive composition of the present invention can provide a pressure-sensitive adhesive having low time-dependency of dependability and adhesion strength and having excellent interfacial adhesion strength. After being applied to an optical member such as a polarizing plate, the pressure-sensitive adhesive composition exhibits excellent interfacial adhesion strength and maintains excellent dependability without time-dependency.

The bistable liquid crystal film is characterized as having two modes, a transparent mode and a scattering mode, with transitions between the two modes being accomplished by voltage pulses with no need to maintain a voltage across the film in order to maintain it in a particular mode. The ionic dopant is an ionic mesogen, preferably an ionic metal-organic mesogen.
