Claims
- 1. 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.
- 2. A display as claimed in claim 1, further including reflection plates arranged at one of the following positions: between the upper and lower substrates and at a position in a lower portion of the display.
- 3. An active matrix LCD, comprising:
- a plurality of pixel electrodes arranged in a matrix contour;
- a substrate on a pixel electrode side including pixel driving elements disposed opposing the pixel electrodes;
- an opposing substrate including electrodes arranged opposing the pixel electrodes; and
- a liquid crystal layer interposed between the opposing substrate and the pixel electrodes, said liquid crystal layer comprising phase-change guest-host (PCGH) mode liquid crystal,
- wherein the substrate on the pixel electrode side includes a glass substrate,
- reflection plates arranged on a surface of the substrate, the surface being brought into contact with the liquid crystal,
- the opposing substrate includes a plastic film substrate having a thickness of 0.6 mm or less,
- the opposing substrate is arranged on a viewing side of the display,
- tablet means for detecting coordinates disposed between the surface of the 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 liquid crystal.
- 4. A display as claimed in claim 3, wherein the display is an active matrix display driven by TFTs.
- 5. A display as claimed in claim 3, wherein the display is a reflection-type display of PCGH mode driven by TFTs.
- 6. A display as claimed in claim 3, further including pen input electrodes.
- 7. A display as claimed in claim 3, wherein the pixel electrodes include metallic reflection electrodes.
