Technical Problem
The present invention related to a LCD (Liquid Crystal Display) getter in which could make possible to handle a high vacuum level by absorbing remaining gases inside of a closed container with chemical reaction in a first vacuum handled by vacuum pump, especially which could make to use exclusively in CCFL (Cold Cathode Fluorescent Lamp) of TFT-LCD (Thin Film Transistor - Liquid Crystal Display) including mercury with structural element of the getter. Also, the getter of the present invention could make not only to handle FFL (Flat Fluorescent Lamp) in a surface back lighting method of TFT- LCD and a high vacuum level including a certain amount of mercury, but also a kind of a inert gas lamp including very small amount of mercury.
In general, a getter after exhaust vacuum pump was having a special quality to be able to absorbing well to get rid of gases chemically, many metal components can be manufactured as a state of mixture, inter-metallic compound and alloy, which is based on a condition of use the getter through lamp manufactured process and a components of remaining gases in a lamp.
Thus, many kinds of getters could be manufactured by the type and organized state (alloy, inter-metallic compound and mixture) of the getter, so the effectiveness of the getter might be differed in components, organized rates and qualities of components. Therefore, there were many developments of the getter depend on different components and organized rates through investment and R&D for making a high quality of the getter. The R&D of the getter might be developed and continuously at present. Meanwhile, there was one of the getter CCFL (Cold Cathode
Fluorescent Lamp) of TFT-LCD (Thin Film Transistor - Liquid Crystal Display).
The lamp was to make possible to apply for the products we might meet daily such as PCs, notebook PCs, LCD TVs, mobile phones, videophones and automobile navigators. However, there was not a proper getter manufactured as being able to use the getter separately for the lamp every time to make the lamp in the prior getter. In another word, the prior getter used to cut the getter in a fixed size each manufacturing the lamp because the prior getter used a manufactured getter to adhere thinly the getter powder on a thin metal sheet surface and used products to put getter powder inside of a groove of square shape as a long wire form. Therefore the getter powder with containing mercury could be separately from the getter when the getter is cut. This was not only harmful cause of working environment but also the getter could not be manufactured as a fixed quality by a declination of the degree of vacuum and the amount of mercury because the amount of inputting getter is not fixed as separation rate of the getter powder with containing mercury. Moreover, the other problem was that a getter might not be inputted smoothly due to sticking when the getter was inputted into a lamp in a manufacturing process because the prior getter was a product to put the getter powder inside of a groove of square shape as a long wire form.
Technical Solution
A getter of the present invention is designed and manufactured by a mixture of metal and mercury chemically as input getter powder in a cylinder container as a cup shape and a piece of cylinder that can make possible not only to input the getter into a lamp simply but also to input a certain amount of mercury inside of a lamp and execution of a role of the getter.
Meanwhile, a getter of the present invention has the functions of
removing chemically remaining gases in backlight to create high vacuum level and of dispensing mercury into it so that no additional process of mercury input is required. That is, this getter can create high vacuum level and dispense mercury as vapor at the same time. Especially, the getter can hit up evenly among all by a high frequency to match productions, qualities of containers and shapes, and the mercury can emit only in the range of temperature at 450~900°C for the getter. In addition, the present invention obviously makes possible to be able to decrease badness of the getter and to increase a function for emitting mercury and degree of vacuum by only high frequency to set the range of activation temperature as the getter is mainly absorbing gases and emitting temperature range of the mercury with emitting a certain amount of mercury.
Advantageous Effects A getter of the present invention can make possible to use any lamp that is used for the use of luminescence, especially it can be used exclusively in CCFL (Cold Cathode Fluorescent Lamp) of TFT-LCD (Thin Film Transistor - Liquid Crystal Display). The CCFL of TFT-LCD uses extensively for products we meet daily such as PCs, notebook PCs, LCD TVs, mobile phones, videophones and automobile navigators, the inside of the lamp is applied a getter for improving the degree of vacuum. Also mercury is put into the inside of the lamp for the use of luminescence.
The getter of the present invention not only increases effect to compare with the prior method to put mercury separately but also is easy to input the getter inside of a lamp as inputting a getter powder in a cylinder container as a cup shape and a piece of cylinder of the getter because the getter is
manufactured to be able to input a certain amount of mercury as always the state of gas from the getter of the state of amalgam inside of the lamp.
Also, the getter of the present invention to input to vaporize mercury as the state of gas is the ideal in the manufacturing lamp as needed mercury because the world absolutely prefer to manufacturing as the use of the smallest amount of mercury due to the problem of an environmental harmfulness of the world.
Especially, the getter of the present invention is not changing the existing process in manufacture to apply the getter to harmonize the production of the getter, the quality of a container, the shape of the container, but the getter makes possible to increase degree of vacuum and mainly emitting mercury to fix only the range of the temperature 450~900°C by once of the high frequency heating.

Mode for the Invention
The following expression as a getter of the present invention through Figure 6 give expression to be used manufacturing process of a lamp based on CCFL (Cold Cathode Fluorescent Lamp) of TFT-LCD (Thin Film Transistor - Liquid Crystal Display). First step of the manufacturing process of a lamp gives form to 1st vacuum to absorb inside air of the lamp in state of heating at about 4000C by a vacuum pump (S100).
Second step of the manufacturing process of a lamp closes up an upper part (120) of the lamp (S200). Third step of the manufacturing process of a lamp is that the lamp gives form to high level of a vacuum as absorbing the remaining air inside of the lamp by a chemical reaction if the getter is activated as heating an inserted getter (100) by high frequency at 450~900°C inside of the lamp. Meanwhile, mercury is emitted from the getter as the mercury is vaporized in which was a state of amalgam inside of the getter if the getter applies heat to by the high frequency, the emitting mercury moves to lower temperature so automatically the mercury moves to inside of the lamp (S300).
Fourth step of the manufacturing process of a lamp is completed to cut and close a concave part (130) with an inserted electrode of the lamp at the same time if mercury moves to inside (140) of the lamp (S140).
As the above-mentioned container of the getter can be used to choose
one of the following materials such as nickel, stainless steel, nickel-plating in stainless steel, iron, nickel-plating in iron, clad of iron and copper, copper, nickel-plating in copper, molybdenum, and titanium material, the size and type of the container is about diameter 07~7mm, heights 0.5~20mm as cylinder container such as shape of a cup, the container as itself can be used an electrode in both sides of the lamp.
The present invention is not limited to the above embodiment. As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are mot limited by any of the details of the foregoing description, unless otherwise specified, but rather should be constructed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
