A multilayer film having electrically controllable optical properties. The multilayer film has a first carrier film, a first planar electrode, an active layer having one or more layers in sequence, a second planar electrode, and a second carrier film, arranged one above the other in a planar manner. The first planar electrode and the active layer and optionally the second planar electrode are divided by at least one insulation line into at least two segments that are electrically insulated from one another. The insulation line is introduced with a laser through one of the carrier films and into the first planar electrode and the active layer and optionally the second planar electrode.

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.

A backlight module includes a back cover, a light source panel positioned on the back cover, a frame connected with the back cover and an optical film assembled to the frame. A pair of reflective plates are positioned between the frame and the back cover, and a plurality of through holes are defined on the pair of reflective plates. A chamber is cooperatively defined between the pair of reflective plates and the back cover, and inner surfaces of the chamber have a high reflectivity.

A bistable liquid crystal film, comprising: a first transparent flexible film coated with conductive material; a second transparent flexible film; at least one layer of liquid crystal dispersions disposed between the transparent flexible conductive films; and an ionic dopant disposed within the layer of liquid crystal dispersions. 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.
