Abstract
The invention discloses a method for sealing an ultra-thin shadow mask plasma display. The method comprises the following steps of: cleaning and drying a shadow mask, first thick glass and second thick glass; positioning the shadow mask between the first and second thick glass and fixing the two sides of the shadow mask by using a first sealing clamp and a second sealing clamp; putting the shadow mask in a vacuum sealing furnace for pre-burning after fixing the shadow mask, wherein the pre-burning comprises an AB phase of raising the temperature, a BC phase of keeping temperature and a CD phase of lowering the temperature; cleaning the shadow mask after the pre-burning; aligning and attaching the front glass substrate of the display, the back glass substrate coated with a sealing frame, and the upper and lower surfaces of the shadow mask, placing the product obtained between the first thick glass and the second thick glass to form a sealing combination and fixing the sealing combination by using the first sealing clamp and the second sealing clamp; putting the sealing composition in the sealing furnace; setting the sintering temperature and the time; sealing the ultra-thin shadow mask plasma display; and filling working gas.
Description
Technical field
The present invention relates to a kind of method for sealing of display screen, especially at the method for sealing of ultra-thin shadow mask plasma display.
Background technology
General shadow mask plasma display manufacturing process comprises header board manufacturing process, back plate manufacturing process and metal shadow mask manufacturing process at present, after above-mentioned three parts are finished, utilize low-melting glass to carry out sealing-in, after carrying out bakeout degassing, charge into working gas, finish the making of display screen.
But be used for ultrathin shadow mask type ion display screen glass substrate thickness very little (less than 1mm), can produce oxidation and contaminating impurity unavoidably in the shadow mask preservation process, form small burr, maximum temperature can reach 450 ℃ in the sealing-in process, the ultra-thin glass substrate can soften, differ bigger with the thermal stress of metal shadow mask, therefore the front and back glass substrate need bear and the local stress that produces, because ultra-thin glass base plate deformation holding capacity is much smaller than common plasma panel glass substrate, thereby make ultra-thin display screen in the sealing-in process, be easy to generate slight crack and depression points, cause ultra-thin display screen sealing-in failure.
Summary of the invention
Technical problem: the objective of the invention is in the method for sealing at existing ultra-thin plasma panel, shadow mask is not carried out special processing, thereby cause the low problem of ultra-thin plasma panel sealing-in success rate, propose a kind of ultra-thin shadow mask plasma display method for sealing that can improve the sealing-in success rate.
Technical scheme:
A kind of method for sealing of ultrathin shadow mask type plasma panel may further comprise the steps:
Step 1 is dried shadow mask, first heavy sheet glass and second heavy sheet glass with ultrasonic waves for cleaning;
Shadow mask after step 2 will be dried places between first heavy sheet glass and second heavy sheet glass and obtains the pre-burning assembly, and with first sealing-in folder and second sealing-in folder pre-burning assembly both sides is fixed;
After the pre-burning-out of step 4, shadow mask is taken out from the pre-burning assembly, use the dust-free paper wiping again, and dry with ultrasonic waves for cleaning;
Beneficial effect: the present invention is directed to ultra-thin plasma display screen substrate stress and bear relatively poorly, after shadow mask cleaned, utilize two blocks of heavy sheet glass to fix, guarantee the smooth of shadow mask; Control temperature and time in the sealing-in stove then, carry out pre-burning, cleaning, drying once more after finishing carries out sealing-in.Through the shadow mask after the pre-burning processing, effectively the place to go impurity and burr, the unstable strong point under hot conditions has been got rid of on the shadow mask in pre-burning simultaneously, improved shadow mask stability at high temperature, make super shadow mask type plasma display screen when sealing-in, front-back baseboard is stressed has evenly avoided the generation of sags and crests and slight crack, has improved the sealing-in success rate.
