Abstract:
A liquid crystal display (LCD) with integrated tablet, comprising:an upper substrate on a viewing side on which electrodes are formed to drive liquid crystal;a lower substrate on an opposing side on which electrodes are formed at positions to drive liquid crystal interposed between the upper substrate and the lower substrate;a liquid crystal of phase-change guest-host (PCGH) mode interposed between the upper substrate and the lower substrate;light illuminating means arranged at a position in a lower portion of the LCD;reflection plates arranged on a surface of the lower substrate, the surface being brought into contact with the liquid crystal,tablet means for detecting coordinates disposed between the surface of the lower substrate and the liquid crystal driving electrodes,the tablet means not preventing transmission of light from the light illuminating means;wherein the transmittivity of said PCGH liquid crystal remains substantially unchanged when a gap thickness of said liquid crystal changes due to pressure on said tablet and said upper substrate.
