Abstract

This invention relates to a method for processing plasma black stripes including manufacturing a printing board in the same width with the non-luminous region-the back stripe of a plasma display, applying a silk screen printing method to print a light sensitive black slurry on the non-luminous region of the upper base plate by the printing board to form a black pattern to be dried then exposed to form an exposed pattern with a mother board of a black stripe pattern by an exposing machine finally to be developed in a developing solution to get the black stripe.

Description

A kind of manufacture method of black strip of plasma display

Technical field

The invention belongs to the gas discharge technical field, be specifically related to a kind of manufacture method of black strip of plasma display.

Background technology

For brightness and the resolution that improves plasma panel, more and more higher to the fineness requirement of lines, the method for traditional silk screen printing making figure can not satisfy the requirement for the resolution more than the XGA.The method of extensive use at present is the method for photoetching making figure, the method not only can be made meticulous figure fast but also also is to realize very easily for the making of some complex figures, be greatly increased with regard to the development that makes plasma display like this, not only can make meticulous linear pattern electrode and barrier figure but also also can satisfy, such as now having made ripe intersecting parallels barrier and T type electrode for the making of the nonlinear type figure of complexity.

In the brightness and resolution raising of display screen, also be determined to carry out sth important equally for the raising of its contrast.The method of making secret note in improving all multi-methods of contrast in front on the plate is effective method, and dark strip part also is absolutely necessary on other display screen of XGA level.Along with the fineness of the raising secret note of electrode pattern resolution also will improve naturally, so the photoetching process main method that become secret note to make.Present photosensitive black stripe slurry adopts the slurry identical with the Bus electrode slurry of black, so the cost of slurry is quite high, and that photolithographic greatest drawback is exactly the waste of material is serious, the cost height.

Summary of the invention

The objective of the invention is to overcome the shortcoming of above-mentioned prior art, provide a kind of and when reducing cost, can produce meticulous figure again, also can form the manufacture method of the black strip of plasma display of nonlinear black strip pattern.

For achieving the above object, the technical solution used in the present invention is: at first make the printed panel identical with the non-light-emitting area width of plasma display, after the Bus electrode completes, adopt silk screen print method that photosensitive black wash material is printed on by printed panel in the non-light-emitting area of upper substrate, form black graphics; Then with the black graphics drying, utilize the motherboard of exposure machine by black strip pattern after the drying to the printed pattern formation exposure figure that exposes; Develop by developer solution more at last and can obtain secret note.

The present invention combines by silk screen print method and photoetching process and makes secret note, black stripe slurry just is coated on non-light-emitting area and is not all to be covered with slurry on whole screen, significantly reduced the use amount of photosensitive pulp, reduce cost, adopted photoetching process to reach the fineness requirement of figure again simultaneously.

Description of drawings

Fig. 1-Fig. 4 is the process chart of making step of the present invention.

Embodiment

Below in conjunction with accompanying drawing preparation method of the present invention is described in further detail.

Referring to Fig. 1, at first make transparent ITO electrode 2 on the upper substrate 1 of plasma panel, and then make Bus electrode 3 by photoetching process on ITO electrode 2, the lower floor of this Bus electrode is a black paste, the upper strata is the Ag slurry of white, and two kinds are photosensitive slurry.The many employings of the slurry of the general secret note photosensitive paste identical with the black wash material of Bus electrode because the cost of photosensitive paste is higher, therefore adopts traditional photoetching process just to increase the cost that secret note is made.Referring to Fig. 2, making with the non-light-emitting area of plasma display then is the identical printed panel of secret note width, adopts silk screen print method that photosensitive black wash material is printed on by printed panel in the non-light-emitting area of upper substrate 1, forms black graphics 4; The figure of this printed panel and the line pattern of non-light-emitting area are in full accord, promptly allow black stripe slurry be covered with whole non-light-emitting area, rather than black stripe slurry is covered with whole screen, use existing silk screen print method that the precision that black stripe slurry is covered with on non-light-emitting area can be reached fully here; Referring to Fig. 3,, utilize the motherboard of exposure machine by black strip pattern printed pattern 4 to be exposed after the drying and form exposure figure 5 according to the secret note preparation technology of routine then with secret note preparation technology's drying of black graphics 4 according to routine; Referring to Fig. 4, the last development by developer solution according to the secret note preparation technology of routine again can obtain secret note 6.

The secret note precision of producing according to preparation method of the present invention can satisfy the requirement of the display screen of XGA rank resolution fully.Here the graphics shape of secret note is not limited to linear pattern completely, with the secret note width of barrier overlapping can be suitable wideer, with further raising contrast.The present invention has saved slurry under the prerequisite that keeps the black strip pattern fineness, reduced cost of manufacture.

Claims

1, a kind of manufacture method of black strip of plasma display is characterized in that:

1) at first makes the printed panel identical, after Bus electrode [3] completes, adopt silk screen print method that photosensitive black wash material is printed on by printed panel in the non-light-emitting area of upper substrate [1], form black graphics [4] with the non-light-emitting area width of plasma display;

2) then with black graphics [4] drying, the motherboard that utilizes exposure machine to pass through black strip pattern after the drying exposes to printed pattern [4] and forms exposure figure [5];

3) develop by developer solution more at last and can obtain secret note [6].
