An erasing device for erasing the liquid crystal paper is not permanently connected to the liquid crystal paper.The plastic sheets remain black except for a five-degree temperature range in which they display a.This phenomenon was confirmed in. more Optical bistability and the effect of a delayed feedback on instabilities pointing out that the transmitted light from the system can be periodic or chaotic in time under certain conditions are discussed.Pressure with a stylus draws a monochromatic color image which is the reflective color of the cholesteric planar texture on a black or contrasting color background.

When the non-reflective liquid crystal is induced to flow such as under the pressure of a pointed stylus the reflective texture is induced under the tip of the stylus.A sheet is therefore cleared by inserting it into a device that applies heat momentarily to the sheet until it clears or erases.Now the student takes a swing and hits the sheet with the head of the mallet.

A large rubber mallet has been sitting for some time on the tabletop, as has the liquid crystal sensor sheet.Find great deals on eBay for liquid crystal paper and tan beads.

This surface treatment is applied to cause the cholesteric liquid crystal in the polymer dispersion of the liquid crystal layer 28 to favor the non-reflective texture upon application of heat sufficient to untwist the cholesteric liquid crystal or drive the liquid crystal to the isotropic state.A sheet that needs to be cleared is inserted in or attached to the device that applies a voltage pulse or pulses to the electrodes of sufficient magnitude to clear the sheet.

One uses liquid crystal paper in the same way normal writing paper is used for hand writing or drawing pictures.The sheet of liquid crystal paper is erased or cleared when voltage pulses of a suitable waveform are applied via the electrodes.
