Abstract
The utility model discloses a protective cover sheet complex with a viewing angle compensating layer. The protective cover sheet complex with the viewing angle compensating layer comprises a carrier substrate, wherein the upper surface of the carrier substrate is coated with the viewing angle compensating layer; and a triacetyl cellulose layer is arranged between the viewing angle compensating layer and the carrier substrate. The protective cover sheet complex with the viewing angle compensating layer is simple in structure and reasonable in design, can be manufactured by a relatively conventional production technology and has a relatively significant practical meaning.
Description
Technical field
The utility model relates to the LCD Technology field, and especially a kind of cover plate of in the preparation process of cover plate and polarization plates, protecting avoids wearing and tearing and the dirty protectiveness cover plate complex with viewing angle layer of compensation.
Background technology
Transparent resin film is widely used in various optical fields, and general resin molding prepares through melt extrusion methods or casting method.The film of melt extruded preparation is inappropriate for optical applications usually, and main cause is that the film of melt extruded demonstrates the optical birefringence of high level, makes that the film flatness of preparation is very poor.The preparation blooming although casting method is widely used, the curtain coating technology has a lot of deficiencies, and one is that curtain coating has tangible optical birefringence, and two can not implement accurately that a plurality of layer and dope viscosity are restricted etc.
Therefore, prior art awaits improving and improving.
Summary of the invention
For overcoming the weak point that prior art exists, the purpose of the utility model provides a kind of cover plate of in the preparation process of cover plate and polarization plates, protecting and avoids wearing and tearing and the dirty protectiveness cover plate complex with viewing angle layer of compensation.
The utility model technical scheme that is adopted that achieves the above object is: a kind of protectiveness cover plate complex with viewing angle layer of compensation; Comprise carrier substrate; The upper surface of described carrier substrate is coated with the viewing angle layer of compensation, is provided with the tri acetyl cellulose layer between described viewing angle layer of compensation and the carrier substrate.
Compared with prior art; The beneficial effect of the utility model is: owing to adopt the protectiveness cover plate complex of said structure; The cover plate complex that promptly has removable carrier substrate and the peelable protective seam of choosing wantonly makes it in the preparation process of cover plate and polarization plates, protect said cover plate to avoid wearing and tearing and dirty having a significant effect.The utility model is simple in structure, reasonable in design, adopts comparatively conventional production technology to be prepared from, and has comparatively significant Practical significance.
Description of drawings
Accompanying drawing 1 is the structural representation that the utlity model has the protectiveness cover plate complex of viewing angle layer of compensation.
Each label is respectively among the figure: (1) carrier substrate, (2) viewing angle layer of compensation, (3) tri acetyl cellulose layer.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to specify:
Referring to Fig. 1; A kind of protectiveness cover plate complex of the utility model with viewing angle layer of compensation; Comprise carrier substrate 1, the upper surface of described carrier substrate 1 is coated with viewing angle layer of compensation 2, is provided with tri acetyl cellulose layer 3 between described viewing angle layer of compensation 2 and the carrier substrate 1.
Described carrier substrate 1 is the polyethylene terephthalate carrier substrate, and described viewing angle layer of compensation 2 is the layers that contain polyester terephthalate-common-isophthalic acid ester.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified to the equivalent embodiment of equivalent variations; But all the utility model technical scheme contents that do not break away from, all still belong in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did according to the technical spirit of the utility model.
