More recently they have begun taking over from conventional TVs and computer monitors. Car instruments are likely to be their next application.
Viewing in bright light has been a problem for current technology grey-face LCDs, but Japanese electronics maker Sharp recently launched an LCD display that it says is indistinguishable at a glance from a mechanical needle on a dial. Sharp says its new LCD has the highest contrast ratio of any LCD panel — at 1500:1 it's triple that of previous versions — and can reproduce a deep black colour that would allow it to be used as a multi-function replacement for a conventional speedometer.
When the car was driving forward the LCD would appear as a speedometer but in reverse it could just as easily act as the screen for a reversing camera.
Sharp has also developed double and triple-view LCDs which show different images when viewed from different angles. In a car, a double-view LCD could allow the driver to view an instrument panel while a front-seat passenger could watch a movie on the same display. The system works by showing left and right images on adjoining image cells in the display behind a parallax screen full of tiny holes. The screen blocks either the left or right images, depending on from which side it is viewed.
