Description

Mask frame assembly for organic evaporation and encapsulation for fabrication of ｗｈｉｔｅ ＯＬＥＤ panel during manufacturing process, manufacturing method and apparatus for manufacturing the same.

The present invention relates to a mask frame assembly for organic deposition and encapsulation, a manufacturing method and a manufacturing apparatus for producing a white OLED panel in a TV manufacturing process for white OLED, in detail, more than four generations of white OLED that is in the spotlight with AMOLED. The present invention relates to a mask frame assembly manufactured by using a plurality of metal stick masks, a method for manufacturing the same, and an apparatus for manufacturing the same.

OLEDs (organic light emitting diodes) have a much faster reaction rate than thin film transistor liquid crystal displays (TFT LCDs). The self-illumination reduces thickness and weight by one third without backlight, and is a next-generation display with a wide viewing angle and low power consumption.

These OLEDs are divided into AM type (active) and PM type (passive). PMOLED has lower manufacturing cost than AMOLED and has limitations in power consumption, lifespan and resolution. Since AMOLED has TFT and capacitor in each pixel and is excellent in terms of power consumption, lifespan, and resolution, the manufacturing cost is increased due to the manufacture of TFT. Most of all, AMOLED's strength is image quality competitiveness. Compared to LCD, the biggest competitor, the color reproduction rate is 30 percentage points higher and the contrast ratio is 20 times better. Afterimage of video, the biggest weakness of LCD, is not found in AMOLED. This is because LCD creates a somewhat complicated screen by passing an indirect light source called backlight through liquid crystal, color filter, etc., while AMOLED reproduces natural color screen by emitting organic material by itself. Moreover, OLED has a simple structure compared to LCD, which is very advantageous in terms of components in manufacturing.

However, in terms of OLED material cost, driver circuit, and driver IC, OLED depreciation accounts for half of the total cost. This is because OLED is not yet popularized to consumers and it is difficult to see the cost effect of manufacturing by mass production.

Because of this reality, the display technology that is emerging recently is White OLED technology. To easily explain the White OLED technology, the merits of LCD panel and AMOLED panel are hybridization technology.

That is, it is a technology to display the color of the RGB color filter by arranging the white OLED and the TFT having a switching function on the RGB color filter representing the color to switch the self-emitting white OLED to the TFT.

If the white OLED panel can be enlarged, it will be able to provide high-quality display panels comparable to LCD-level mass production yields and AMOLED.

However, it is still difficult to provide high-quality display panels because the technology for mass production of LCD or PDP-class 40 inch or more or 8 generation or more white OLED panels is not provided.

Of course, a large size coil is provided and implemented in the ledger method, but it is difficult to enlarge the size by using a mask made of one ledger because the supply size of the coil, which is a raw material of the mask, is not produced in the size required for large size. . In other words, due to profitability, coil producers do not produce coils of the size required by white OLED display companies.

In addition, in order to manufacture large quantities of white OLED panels of 4th generation or more, if a mask frame assembly manufacturing technology for white OLEDs capable of depositing white OLEDs is supported, it can be mass-produced while overcoming yield problems, but most mask frame assemblies are manufactured. This is because the manufacturing technology and devices are used to manufacture LCD or AMOLED panels, so it is difficult to apply them directly to the mask frame assembly for white OLED.

The specific reason is that in order to cope with each pixel for the deposition of organic material for R, G, and B in the case of FMM Type OLED among the manufacturing method or manufacturing apparatus of mask frame assembly for AMOLED, which is being developed in large-scale LCD or large-sized technology. Fine Metal Mask with dense holes is used, and metal deposition and encapsulation are using OPEN Mask, whereas White OLED uses Color Filter glass used in LCD manufacturing process to cope with R, G, and B colors. Open mask is used in both white organic material deposition and metal deposition and encapsulation processes. Therefore, it is not necessary to apply Fine Metal Mask, and in case of making Open Mask, it is difficult to apply due to the limitation of Mask Coil Size in case of manufacturing by multiplying the inside of the ledger.

In addition, in the conventional method of manufacturing the multi-sided inside the ledger as shown in FIG. 11, since it is difficult to precisely position it while maintaining the tension without sagging of the mask, it is difficult to manufacture a mask frame assembly for a large area white OLED. to be.

In other words, if the mask does not have tension and the position is not precise, mask center deflection occurs, which is detrimental to shadow and deposition position, and thus a high-definition white OLED panel cannot be provided, resulting in a drop in yield.

An object of the present invention for solving the above problems is to move and position the stick mask to be divided into holes of the area that needs a large frame to mass-produce 4 or more generations of white OLED panels, the mask used during the division is sagging in the center, etc. The present invention provides a fabrication method, a fabrication apparatus, and a mask frame assembly manufactured therefrom which are subjected to tension after welding so as not to occur.
