The present invention relates to a tip tube for a surface light source panel and a method for manufacturing a surface light source panel using the same, and more particularly, in the manufacturing process of the surface light source panel, the surface light source panel such as an exhaust pipe and a getter tube while maintaining a working temperature at a constant temperature. By allowing tip off to the tip tube, the reliability of the surface light source panel can be improved, and the defect rate of the product is minimized during the manufacturing of the surface light source panel, and the unnecessary waiting time due to the rise and fall of the working temperature. By reducing the number, the surface light source panel manufacturing process can be shortened.

In addition, the present invention by minimizing the remaining tip of the surface light source panel, to prevent damage, defects, etc. of the surface light source panel generated due to the remaining tip during the surface light source panel manufacturing process, as well as the display of the surface light source panel By minimizing the thickness of the device, it is to improve the competitiveness of the product comprising the surface light source panel of the present invention.

In particular, by allowing one surface light source panel tip tube to perform exhaust and getter treatment, the uniformity of luminance of the surface light source panel can be further improved.

Recently, a display device widely used and used is a plasma display panel (PDP) or a liquid crystal display (LCD). Since the LCD does not produce a light source by itself by using the transmittance of the internal liquid crystal, it uses a light source having self-luminous properties such as a backlight, and recently, uses a flat fluorescent lamp to obtain uniform luminance. The PDP has self-luminous property by generating visible light from fluorescent material by gas ionization.

Accordingly, the surface light source panel of the present invention in the technical field of the present invention is a surface shape of a self-luminous light source that emits light, which is electromagnetic waves in the visible light region, such as a backlight of a LCD, a PDP, a flat panel indoor lighting lamp, or the like. It is what is collectively comprised in the form of a panel.

Meanwhile, looking at the general manufacturing process of the surface light source panel as described above, the bonding / sealing process of the upper and lower plate alignment, clipping, heating, de-clipping, and exhaust gas (Ont Gassing) ), Exhaust pipe primary tip-off, exhaust pipe secondary tip-off, getter treatment, getter tip-off exhaust and getter treatment, and diffusion process.

In the bonding / sealing process, the components of the surface light source panel such as the upper plate and the lower plate, the exhaust pipe and the getter tube are aligned and bonded at room temperature, and then the components and the exhaust pipe of the surface light source panel bonded by heating up at 420 ° C. to 480 ° C. And the getter tube is sealed, the work temperature is lowered to room temperature (25 ℃) when the bonding and sealing is completed.

The exhaust and getter treatment process is to increase the working temperature from room temperature to 340 ℃ ~ 380 ℃, remove the impurity gas inside the bonded and sealed surface light source panel, lowering the working temperature to room temperature when the exhaust is completed exhaust pipe 1 Second tip off, and after getter treatment tip off getter tube.

In the diffusion process, mercury injected into the surface light source panel by the getter treatment is diffused into the surface light source panel. The temperature is raised from room temperature to 340 ° C. to 380 ° C. to diffuse mercury. Upon completion, the working temperature is lowered to room temperature.

In the manufacturing process of the surface light source panel as described above, if the increase and decrease of the working temperature occurs repeatedly, cracks or stresses are generated in each component (top plate, bottom plate, etc.) constituting the surface light source panel, the surface light source There was a problem of causing a defect of the panel and lowering the productivity.

Despite the above problems, the reason why the surface light source panel was manufactured while repeating the increase and decrease of the working temperature was because of the tip-off of the exhaust pipe for vacuuming the inside of the surface light source panel and mercury into the surface light source panel. This is due to the tip off of the getter tube used in the getter process for injection.

In order to tip off the exhaust pipe and the getter pipe, while the working temperature is lowered to room temperature, the tip off portion is locally heated to partially melt the exhaust pipe and the getter pipe, and the partially melted part is sealed, thereby This is because tip off is made.

In addition, when the tip of the exhaust pipe and the getter pipe is turned off, the torch-type heating means is used, which causes the surface light source panel to be heated as well as the molten portion of the exhaust pipe and the getter pipe, thereby causing damage to the surface light source panel. .

Therefore, the tip-off position of the exhaust pipe and the getter pipe requires a sufficient distance such that the surface light source panel is not heated, and for this reason, after the manufacturing process of the surface light source panel is completed, the exhaust pipe and the getter pipe have a considerable length. Has left the tip.

The remaining tip of the exhaust pipe and the getter tube not only increases the overall thickness of the display device, but also frequently causes breakage of the remaining tip itself, which lowers the productivity of the product, and increases the internal space of the remaining tip. As the length increases, the internal space thereof increases, which further lowers the uniformity of luminance with respect to light emitted from the display device.

In order to solve the above problems, the present invention is a surface light source panel in the manufacturing process, while maintaining the working temperature at a constant temperature to the tip surface for the surface light source panel tip tube such as exhaust pipe and getter pipe can be made An object of the present invention is to provide a tip tube for a light source panel and a method for manufacturing a surface light source panel using the same.

In addition, an object of the present invention is to provide a tip tube for a surface light source panel that can minimize the remaining tip of the surface light source panel and a method of manufacturing a surface light source panel using the same.

Meanwhile, in manufacturing the surface light source panel, it is very important to form a light source to have a uniform brightness, but there is a problem that the brightness of the surface light source panel is further lowered due to two different remaining tips of the exhaust pipe and the getter pipe. To solve this problem, a method is required.

An object of the present invention as described above is to provide a surface light source panel tip tube that can perform the exhaust and getter treatment using one surface light source panel tip tube, and a method of manufacturing a surface light source panel using the same.

In order to achieve the above object, the surface light source panel tip tube using the surface light source panel tip tube according to the present invention has a space hole formed to be opened in one direction is formed therein, one side formed by opening the space hole A main body tube fixedly attached to one side of the surface light source panel, and a second sealing member fixedly installed in one side of the main body tube and having a first through hole penetrating in a direction corresponding to the space hole.

The exhaust process (S200) is an out-gassing process of removing the moisture and residual impurity gas inside the surface light source panel through the exhaust tip tube among the surface light source panel tip tubes to vacuum the inside of the surface light source panel (S210). And injecting a discharge gas such as argon or neon into the inside of the surface light source panel through the exhaust tip tube (S220), and sealing (S230) to seal the exhaust tip tube.

In the bonding / sealing process (S100), as shown in FIG. 2, after the bonding process is performed at room temperature, the sealing process is performed by raising the working temperature to a first set temperature (for example, 450 ° C. to 500 ° C.). The exhaust process (S200) and the diffusion process (S300) process each process using a second set temperature (for example, 340 ° C to 400 ° C) as a working temperature, and for exhausting the exhaust process (S200). Tip tube sealing process (S230) and the tip tube sealing process (S320) for the getter of the diffusion process (S300) is processed by locally applying a heat corresponding to the third set temperature (for example, 500 ℃ ~ 600 ℃).
