Embodiment 1

[0030] a. Fabrication of the lower glass substrate 1:

[0031] 1) Use 2g of decontamination powder, analytically pure alcohol, and deionized water to perform ultrasonic cleaning on the glass substrate. There is no strict ratio requirement for alcohol and deionized water. After cleaning, the glass surface does not leave oil stains or stains, and the surface is smooth. The water film is required to be intact.

[0032] 2) On the lower glass substrate 1 glass, coat a layer of photosensitive glue with a thickness of 20 microns to resist the corrosion of glass etching solution, expose and develop through a mask plate, and form an electrode pattern, as shown in the attached image 3 shown;

[0033] 3) Etching the lower substrate glass with a mixture of 40% hydrofluoric acid and pure water in a weight ratio of 4:1, and then peeling off the remaining photosensitive adhesive with a degumming solution, forming a and Groove 2 with consistent electrode pattern, as attached figure 1 show...

Abstract

The invention belongs to the electrovacuum field, and relates to a method for manufacturing a plane surface medium resistance discharging light source. The invention is characterized in that an electrode is printed and sintered in glass groove of an etched lower glass substrate, and then a reflecting layer and a medium layer are printed on the lower glass substrate. Particularly, the method comprises the following steps: a, the manufacture of the lower glass substrate, that is, applying photosensitive glue to the lower substrate glass to form an electrode pattern, subjecting the lower glass substrate to the etching treatment to form a groove which is consistent with the electrode pattern on the lower glass substrate, and subjecting the reflecting layer and the medium layer to printing a plurality of times after the sintering treatment; b, the manufacture of an upper substrate, that is, subjecting the upper glass substrate to ultrasonic cleaning and printing a fluorescent coating on theupper substrate; and c, encapsulating the whole machine, performing the low glass sintering, removing gas and then adding inertia mixed gas including neon and xenon, assembling a drive circuit and aging. The invention has the advantages of reducing the printing frequency of the medium and errors due to contrapostion, and ensuring that the manufacture technology is simple and accurate.

Description

technical field [0001] The invention belongs to the field of electric vacuum and relates to a method for manufacturing a planar dielectric barrier discharge light source. Background technique [0002] (1) In recent years, liquid crystal display LCD technology has achieved rapid development. Liquid crystal displays are generally transmissive, requiring a light source behind the liquid crystal panel to realize luminescent display. Important performance indicators such as brightness, contrast ratio, brightness uniformity and power consumption of LCD have a great relationship with the performance of its backlight source. At present, the backlight commonly used in flat-panel liquid crystal displays is cold-cathode fluorescent lamp CCFL, which has the advantages of high light efficiency and brightness, but its disadvantages are that it takes a long time to reach saturated brightness after lighting, the ignition is greatly affected by the ambient temperature and the life is short....
