Description
Technical field
The present invention relates to polaroid manufacturing technology field, it particularly relates to a kind of double-deck compensation film polaroids of CSTN and
Its manufacture method.
Background technology
CSTN, it is a kind of mobile device colorful display screen, STN LCD colorization, is exactly the CSTN described in us
(Color STN).It is exactly that a FSTN screen adds last layer coloured silk film in fact, and a display picture is formed with tri- pixels of RGB
Vegetarian refreshments.CSTN basic display principles and STN are just the same, and the torsion for only making to add liquid crystal molecule is seen on STN LCD surfaces
Bent angle, but actually far from this way, because the twist angle of increase so that another characteristic of liquid crystal shows, and is exactly double
Refractiveness, ambient incidence upper polaroid becomes a branch of linearly polarized light afterwards, but linearly polarized light is by layer of liquid crystal molecule
When be no longer only distortion polarization direction, but be decomposed into two-beam line-ordinary light and extraordinary ray, this two-beam
Line interferes with each other when outgoing so that STN LCD always show not powered when certain background color (such as
Green and blueness).Therefore it will be seen that STN LCD displaying principle and TN LCD are fundamentally entirely different, it
It make use of the birefringence of liquid crystal.People design a lot of ways to eliminate STN LCD background color, and simplest is exactly to utilize one
It is individual just the same, but two oppositely oriented STN LCD boxes are superimposed so that the two-beam line interfered with each other is again mutual
Compensation is returned, and so as to realize white and black displays, here it is DSTN (Double STN), but DSTN cost is too high, then people
Expect being distorted to simulate a liquid crystal cell with the orientation of one layer of iodine molecule, thus instead of with thin film (phase difference board)
One liquid crystal cell, it is this to be called FSTN (Film STN) so as to realize white and black displays.
But compound one layer of position differs again on the basis of original difference, white point, bubble are easily produced, interior dirt is bad
Control, causes yields low.
The problem of in correlation technique, effective solution is not yet proposed at present.
