LCD Electronic games became popular between 1980 and 1987. They use liquid crystal to display black graphics against a grey background, although many variations of this kind of display exist in both handheld and tabletop form, including clear screens, colour displays and multi-screen games. Nintendo may have set the benchmark with their legendary Game & Watch games, but there are 100s of other fantastic LCD games from the era just waiting to be discovered. Today LCD games are highly prized, with some rare handheld games fetching considerable sums.
