Embodiment 1
The laminate of preparation tool different-thickness liquid crystal layer
Take one and be of a size of 10cm × 10cm and the polyethylene terephthalate substrate that thickness is 100 μm (model PET4100 twists flax fibers and weave (ToyoboCo, Ltd., Japan) purchased from Japan of Japan), on this base material, be coated with an acryl resin layer.An engraving copper wheel is used imprint on acryl resin layer, and simultaneously irradiating ultraviolet light, with formation plural lenses structure (caving inward into bowl-type from acryl resin layer surface, width is 250 μm, and the degree of depth is 40 μm) on acryl resin layer.
It is provided with on the side of lens arrangement to be coated with photo-alignment layer that a thickness is 100nm (model for ROP103, purchased from Rolic) with method of spin coating in this base material.Afterwards, then with light orientation machine (model for PUVDEEP, purchased from USHIO) this both alignment layers is carried out orientation with a predetermined direction (becoming 45 degree of angles with film direct of travel).Finally, one layer of liquid crystal (ultraviolet hardening liquid crystal it is coated with in photo-alignment layer, model is LC242, purchased from Germany BASF, wherein being mixed with a smooth initiator (model is TPO, purchased from Germany BASF), addition accounts for the 1wt% of total amount), make liquid crystal be fully filled with lens arrangement, and to make the another side of liquid crystal layer be flat condition.Thereby can preparing the liquid crystal layer with different-thickness, the thickness of this liquid crystal layer thinnest part is 1 μm, and the thickness in thickness is 41 μm, and thickness difference is 40 μm.
Prepare infrared ray-absorbing layer
Take PETP substrate (the model PET4100 that a thickness is 100 μm, twist flax fibers and weave (ToyoboCo purchased from Japan of Japan, Ltd., Japan)), on one side with the black ink of R.D.S.Webster8 one layer of heat-curing type of bar even spread (solid content 35wt%, main constituent is carbon black, model A92, purchased from Taiwan paper tinsel science and technology (TaipoloTechnologyCo.Ltd., R.O.C.)).After even spread, by the removal of solvents in ink, (hot plate (hotplate) heats, at 70 DEG C 1 minute), to obtain the ink layer that thickness is for 0.3 μm, through with sub-ray spectrometer, (model is for U4100, purchased from HIT) measurement, record under 750nm～1500nm wavelength, overall infrared ray-absorbing layer has the infrared penetration rate of 57.4%.
Infrared ray-absorbing layer is fitted on aforesaid laminate, makes on infrared ray-absorbing layer the one side without ink layer contact with liquid crystal layer.Afterwards, it is sent in volume to volume infrared heater (assemble voluntarily, heater is provided with the infrared lamp that can send 750～1500nm wavelength, power is 110V/300W), heating-up temperature is set in 80 DEG C (hot coupling distances of temperature sensor be heated about 1 centimeter of thing surface), machine speed is 0.2 meter/minute, and overall heat time heating time is 5 minutes.Finally, after completing heating, stand under room temperature environment and be cooled to room temperature, used liquid crystal cycle of annealing.
After liquid crystal layer completes annealing, detect LCD alignment situation with polarizing microscope (model for XP201, purchased from Qinyou Enterprise Co., Ltd.).Acquired results represents in lower section mode after testing, and result is converged whole in table one:
(1) LCD alignment is good, represents with "○", corresponds in region residing for lens arrangement, without any LCD alignment abnormal area in table liquid crystal layer；
(2) LCD alignment still can, represent with " Δ ", corresponding in region residing for lens arrangement in table liquid crystal layer, LCD alignment abnormal area only has 1st～3 district (representing accounting for overall region ratio, it is possible to can be clearer)；
(3) LCD alignment is poor, represents with "×", corresponds in region residing for lens arrangement in table liquid crystal layer, and LCD alignment abnormal area is more than 3rd district.
In test result, with "○" and " Δ " signifier, equal table quality is at tolerance interval, but wherein with "○" signifier, quality is best.
Because sending into the lamination layer structure that rete is a multiple material in infrared heater, when layers of material be heated inequality cause programming rate inequality time, because each layer thermal coefficient of expansion is different, causing integral membrane facial disfigurement, liquid crystal is subjected to this impact when orientation and causes that orientation is abnormal.Producing orientation abnormal wire (disclinationline) that is the region around those abnormal wire time again because of LCD alignment exception, the alignment direction of liquid crystal presents irregular status.Therefore, when light is by this region, the situation of liquid crystal light leak and then the image display quality of the liquid crystal display made by impact can be caused.
