Abstract
A manufacturing method of a line-by-line removing microretarder used on display screens is disclosed. The manufacturing method has the following processes: inclining original retarder films positive and negative 45 DEG C and respectively cutting the original retarder films, and then connecting the cut films into a long roll shape; using a transparent material as a medium, and recombining the positive and negative 45 DEG C retarder films on front-back sides of the transparent material, which means the positive 45 DEG C retarder film is on the front side of the transparent material and the negative45 DEG C retarder film is on the back side of the transparent material; removing original phase difference optical layers according to predetermined gaps so as to interlacedly reserve original phase differences as well as interlacedly remove phase difference values till the values are zero. By using the method of the invention, a finished product needs low costs and has good effects. Processing method is easy and practicable. The product can be widely used and has great market potential.
Description
Technical field
A kind of display screen method for making of removing line by line micro-bit phase difference film.
Background technology
At present, screen stereo display is divided into active electronics shutter mode and passive type rotatory polarization mode, and namely microfacies position compensation way is two kinds.
The implementation of rotatory polarization stereoscopic screen is at the compound one deck micro-bit phase difference of the front end of traditional lcd screen compensate film, thereby is odd-numbered line pixel and even number line pixel two picture group sheets with the image segmentation of actual displayed.The conventional imaging pattern is that the odd-numbered line set is left image, and the even number line set is right image.
The technology mode of existing realization micro-bit phase difference compensate film is: as basic printing opacity carrier, the mode that single face is taked to electroplate line by line liquid crystal is made with high permeability optical material PC sheet or glass sheet.The liquid crystal produce an effect of odd-numbered line makes the phasic difference value wavelength of nominated bank for fixing numerical value and angle, such as 125nm, and+45 degree; The liquid crystal produce an effect of even number line makes the phasic difference value wavelength of nominated bank for fixing numerical value and angle, such as 125nm, and-45 degree, thus realize that the light that this compensate film interlacing sees through is divided into left-handed rotatory polarization and two groups of light of dextrorotation rotatory polarization.
There is following major defect in existing micro-bit phase difference compensate film:
1, apparatus expensive, production capacity are low
Take 46 o'clock stereotelevision screens as example, at present, a whole world month production capacity only is 5000.
2, Compound Machining difficulty
Existing phasic difference compensate film finished product is rigid sheet material.When fitting with existing phasic difference compensate film and LCD display, work pattern is the hard die formula of pasting.The hard work pattern of this hard subsides produces easily and goes to steep the problems such as bad, that contraposition is difficult, curing is difficult.
3, cost is high
Take 46 o'clock stereotelevision screens as example, with existing operating type, the cost of every micro-bit phase difference compensating plate is 225 dollars, and the Compound Machining cost is 100 dollars, is to involve great expense.
Above cost is high, Compound Machining is difficult and the low inferior factor of production capacity, has seriously hindered popularizing and development of rotatory polarization spatical television set.
Summary of the invention
The objective of the invention is to utilize existing finished product phasic difference film as activity bases, take to remove line by line technology mode, original phasic difference value is made zero, and adopt the operating type of spool film, fit with LCD display.Finished product with the present invention makes will exist with the form of mantle, thereby has solved the major defect that exists in the existing compensate film production run.
Technological process of the present invention is as follows:
With original phasic difference film on demand angle positive and negative 45 degree that tilt cut respectively and the growth web-like of plugging into; Take transparent material as medium, the phasic difference film with positive and negative 45 degree is compounded on the pros and cons of transparent material respectively, and namely the front of transparent material is positive 45 degree phasic difference films, and the back side is negative 45 degree phasic difference films; Remove original phasic difference optical layers by predetermined gap, reach when interlacing keeps original phasic difference, the phasic difference value is removed in interlacing, is zero.
The net result that interlacing is removed is: positive odd-numbered line keeps original phasic difference value, and it is zero that even number line is removed; The reverse side even number line keeps original phasic difference value, and it is zero that odd-numbered line is removed.
With the finished product that the present invention makes, light-transmissive film form meet odd-numbered line phasic difference value be 125nm ,+45 degree, meeting even number line phasic difference value is 125nm ,-45 degree.
The finished product made from the present invention has that cost is low, job operation is simple, the accurate characteristics such as efficient of effect, has widely user demand and market potential.
Description of drawings
Accompanying drawing is structural representation of the present invention, also is that specification digest is with scheming.Each label is respectively among the figure: (1) 125nm ,+45 degree phasic difference films, (2) transparent material medium, (3) 125nm ,-45 degree phasic difference films, (4) position phase axle, (5) keep original phase bit position, (6) position phase zero clearing part.
Embodiment
The present invention will be further described now to provide by reference to the accompanying drawings an example.
Embodiment:
Be 0.06mm with original thickness, phasic difference value 125nm phasic difference film on demand angle positive and negative 45 degree that tilt cuts respectively, and the growth web-like of plugging into; Transparent TAC take thickness as 0.08mm is transparent material medium 2, phasic difference film 1,3 with positive and negative 45 degree is compounded on the positive and negative of TAC transparent material medium 2 respectively, the front that is TAC transparent material medium 2 is positive 45 degree phasic difference films, and the back side is negative 45 degree phasic difference films; Hit mode with laser, remove original phasic difference optical layers by predetermined gap, reach when interlacing keeps original phasic difference, the phasic difference value is removed in interlacing, is zero and gets final product.
