Background technology

If general liquid crystal flat panel display is according to driving display mode, can be divided into two kinds on passive matrix and active-matrix type, the simple matrix escope mainly is in upper and lower panel staggered transparency electrode and filling liquid crystal to be set respectively, the clathrate position of electrode crossing is exactly the picture element of liquid crystal panel, the electrode of two directions is that two electrode potentials that provide driving voltage to control picture element by the outside are poor, reaches the rotation that drives liquid crystal in the picture element; The active-matrix escope then is the auxiliary capacitor that switch module is set on each the picture element location point on the panel and stores signal, and it is independently to be controlled by the thin-film transistor component on the picture element that each picture element drives.

No matter be simple matrix escope or active-matrix escope, its panels outside must attach a slice polaroid, main application is to make light source generation phasic difference and the state that presents light and shade when electric field and no electric field are arranged, in order to show captions or image, if it is residual when pollutant such as foreign matter, impurity is arranged between panel and polaroid, then can influence the quality of demonstration, so the liquid crystal panel of display keeps in manufacturing process the cleaning of panel just quite important.

Yet the processing procedure of panel is loaded down with trivial details, each step all might produce pollutant and be attached on the panel, with the STN-LCD processing procedure is example, processing procedure and back processing procedure before it mainly can be divided into, before processing procedure comprise: steps such as the ITO electro-conductive glass is cleaned, photoresistance coating, development, etching, alignment film processing procedure, gap are scattered, frame glue and panel combination become the sky liquid crystal cell; Back processing procedure aspect comprises: panel cutting, liquid crystal are filled, UV glue seals, frictioning, curing, cleaning attach liquid crystal, photoelectric characteristic detection, visual examination, attaching polaroid, module assembling, and the liquid crystal panel of finishing a display is made.

Above-mentioned liquid crystal panel manufacture process, though in dust free room, carry out, but still the generation of pollutant is arranged unavoidably, because the pollution source of liquid crystal panel manufacture process, mainly can be divided into: organic class, the grease class, mineral-type and particulate etc., organic class, the pollution source of grease class has organic solvent (acetone, alcohol, isopropyl alcohol IPA), photoresist, organic resin (UV sealing), liquid crystal, contact oil film etc., and the pollution source of mineral-type has inorganic oxide layer, metallic impurity, and atomic pollution source has dust, chips of glass that cuts or particle etc., therefore at the separate sources pollutant, can use suitable method to clean.

Though in liquid crystal panel manufacture process, quite pay attention to cleaning, but still can not guarantee the existence of panel contamination-free when attaching polaroid, especially when UV glue seals the step of back frictioning, unnecessary UV glue can remain in panel surface, if thoroughly do not remove clean, as shown in Figure 5, after treating curing schedule, the easy-clear more not of the UV glue stain thing 8 on the panel that remains in 7, thus, pollutant 8 is stained with to stick in the attaching face of panel 7 before attaching polaroid 9 and is not removed, and attaches 9 of polaroids this moment and easily produces the situation that bubbles etc. influence display quality, as shown in Figure 6, and the quality and the yield of reduction processing procedure, moreover attach the back segment step that polaroid belongs to the back processing procedure, if fail because of the pollutant between polaroid and panel makes processing procedure, then leading portion multiple tracks processing procedure is all wasted, and causes the cost of processing procedure to increase relatively.

The utility model content

Technical problem underlying to be solved in the utility model is, overcome the above-mentioned defective that prior art exists, and provide a kind of panel construction that is used to make display, make liquid crystal panel when attaching polaroid, the attaching face that can guarantee panel can not produce the pollutant that makes polaroid attach failure, significantly promote attaching the yield of polaroid processing procedure, and then reduce the cost of processing procedure.

The technical scheme that its technical matters that solves the utility model adopts is:

A kind of panel construction that is used to make display; it is characterized in that; one side of its panel is a predetermined attaching face that attaches polaroid; this attaching face is set several spaced diaphragm areas of going up; diaphragm area is provided with a strippable diaphragm respectively on each; this diaphragm has light transmission, and this diaphragm has heatproof 120～150 degree Celsius and has the character of rotten property of chemically-resistant and acid-alkali-corrosive-resisting.

The aforesaid panel construction that is used to make display, the attaching face of panel described diaphragm area gap at interval on each wherein is then for making the reserved area of panel cutting in the display processing procedure.

The beneficial effects of the utility model are, make liquid crystal panel when attaching polaroid, can guarantee that the attaching face of panel can not produce the pollutant that makes polaroid attach failure, significantly promoting the yield that attaches the polaroid processing procedure, and then reduce the cost of processing procedure.
