When wanting to write or draw on LCD MODULE 2, LCD MODULE 2 is applied pressure to change liquid crystal
When the display state of display module 2, for example, with writing pencil or finger pressing LCD MODULE 2 soft transparent substrate 24 with
And convex block 28, convex block 28 again pressurize to liquid crystal layer 25, liquid crystal molecule is from vertical spin structure (focal conic in liquid crystal layer 25
Texture it) is switched to planar spiral structures (planar texture), when incident light enters liquid crystal planer meeting generating period
Bragg reflection, the visible reflectance of specific wavelength is to human eye, into display state.And it is adjustable by changing material prescription
Liquid crystal is to pressure sensitivity, the thickness of speed and person's handwriting.

The direction of field and display active array substrate 21 and soft transparent substrate 24 are arranged vertically, vertical arrangement of untwisting (homeotropic
Texture), incident light does not occur to reflect and scatter across liquid crystal material molecules at this time.After stopping applying high voltage, liquid crystal layer
25 liquid crystal material molecules reenter instantaneous planar spiral structures (transient planar texture), by anti-
Stable planar spiral structures are entered to high pressure and rezero operation.Then using two action of low-voltage pulse (such as 9.5V-18V,
Period can adjust according to temperature) make liquid crystal material molecules enter vertical spin state by snail, visible light is incident at this time
Reflection is not generated afterwards and is directly absorbed by the black absorbing layer of the 21 another substrate (not shown) in lower section of active array substrate, and human eye is made
