In a method of manufacturing an image display apparatus, a first member having an electron-emitting device and a second member having a phosphor which is irradiated with an electron emitted from the electron-emitting device to emit light are seal-bonded in a seal bonding chamber in which a vacuum atmosphere is realized. An aging step for the electron-emitting device is performed before the step of seal-bonding.

In a flat panel display containing a getter material, the getter material is activated during the sealing step, and is partially consumed, if the getter activation temperature is lower than the sealing temperature. On the other hand, a very small part of the getter material is activated if the getter activation temperature is higher than the sealing temperature. The problems are solved by a process comprising the steps of: providing front and rear glass plates of a flat panel display, both supporting the functional elements which are required for the final display; disposing a flat getter device on one of the glass plates at the position determined in the final display; sealingly joining the two glass plates by means of a sealing material which, upon solidification at a temperature T1, gives rise to a solid having a melting temperature higher than T1; baking the thus-produced flat panel display at a temperature higher than T1 while evacuating its inner space through a glass tube left in one of the two glass plates; activating the getter material at a temperature higher than T1; and closing the inner space of the display by nulltipping-offnull the glass tube.

A flat-panel display device having a transparent first plate and a second plate which are disposed in parallel with each other and cooperate to define therebetween an air-tight space in which light is generated for emission through the first plate, the display device including a sealing material for air-tightly sealing the air-tight space along a periphery of the first and second plates, and metallic thin sheets bonded with the sealing material to end faces of the first and second plates such that the metallic thin sheets cover the end faces. The display device is manufactured by applying the sealing material to the end faces such that a peripheral portion of the air-tight space is filled with a mass of the sealing material, forcing the metallic thin sheets onto the end faces such that the metallic thin sheets cover the end faces, and heating the sheets and the sealing material firing the sealing material for air-tightly bonding together the two plates while bonding the metallic thin sheets to the end faces through the sealing material.

A manufacturing method for a gas discharge panel according to the invention can reduce the amount of water and gaseous molecules, which are absorbed into the first and the second substrates, to a minimum by keeping the both substrates under a reduced pressure, and therefore can prevent a degradation of a discharge gas filling the finished panel. As a result, problems in the finished panel such as increase in a discharge starting voltage and generation of an abnormal discharge can be suppressed.

A bonding machine for fabrication of a large size LCD having an upper stage and a lower stage provided in a bonding chamber to face each other, for adsorbing the first and second substrates carried in the bonding chamber, and bonding the substrates together. The bonding machine having supporting means in the bonding chamber, lifting means, and process supplementing means fitted in the bonding chamber so as to be rotatable and movable up/down. The method including loading the first and second substrates on respective stages, driving the supporting means to support the second substrate loaded on the upper stage, and evacuating the bonding chamber, the upper stage adsorbing the second substrate and bonding the first and second substrates together, and lifting the bonded first and second substrates from the lower stage by using the lifting means, and unloading the first and second substrates.
摘要:
A front substrate and a rear substrate are laid on each other with a sealing frit therebetween. The front substrate, the rear substrate and the sealing frit are heated in a chamber and impurity gas is exhausted from both of the substrates by lowering internal pressure of the chamber. The sealing frit is melted in the chamber by further heating the front substrate, the rear substrate and the sealing frit. The sealing frit is solidified in the chamber and sealing up the front substrate and the rear substrate.

In a method for manufacturing a discharge tube including a discharge part, a sealing part formed at an end of the discharge part, and an electrode provided in the discharge part, the method includes inserting an electrode body having the electrode into a portion to be the sealing part that is adjacent to a portion to be the discharge part of a transparent insulating tube serving as a material for the discharge tube, and then sealing the portion to be the sealing part by heating and softening with a combination of a laser beam and a gas burner, thus forming the sealing part. Heat sources are selected suitably according to each region in the portion to be the sealing part, whereby a high-quality discharge tube that is highly resistant to pressure can be manufactured at high production efficiency and low cost.
摘要:
A method for producing a plasma display panel that has a front substrate and a back substrate disposed to face each other. A pre-baking phosphor layer containing a phosphor and an organic binder is formed on at least one of surfaces of the front substrate and the back substrate that are to face each other. A sealing material that softens with heat is applied to the peripheral region of at least one of the surfaces of the front and back substrates that are to face each other. The front and back substrates are disposed to face each other in a stack. The front and back substrates are heated to burn out the organic binder while supplying a dry gas containing oxygen to an internal space that is formed between the front and back substrates.
