Description

Mask frame component for organic deposition and encapsulation, manufacturing method and equipment thereof

technical field

The present invention relates to a mask frame assembly for organic deposition and encapsulation of a white OLED panel in the manufacturing process of a white OLED TV, its manufacturing method and manufacturing equipment, and more specifically relates to a method for combining with an active matrix The organic light-emitting diode panel (AMOLED) and the high-profile white OLED have been enlarged to more than the fourth generation, and the mask frame assembly made by using multiple metal rod masks, its manufacturing method and manufacturing equipment.

Background technique

The reflection speed of OLED (Organic Light Emitting Diode) is much faster than that of Thin Film Transistor Liquid Crystal Display (TFT LCD). In addition, since it can emit light by itself and does not require a backlight, the thickness and weight can be reduced by one-third, and it is a next-generation display with a wide viewing angle and low power consumption structure.

Such OLEDs are classified into AM type (active) and PM type (passive). Compared with the active matrix organic light emitting diode panel (AMOLED), the passive matrix organic light emitting diode panel (PMOLED) has lower production cost, but is limited in power consumption, lifespan and resolution. AMOLED uses TFTs and capacitors in each pixel, and is excellent in terms of power consumption, lifespan, and resolution. Therefore, the disadvantage of high production costs caused by TFT production is ignored, and it is widely developed in various fields at present. And continuous mass production attempts. The biggest advantage of AMOLED lies in its competitiveness in picture quality. Compared with the largest competitor's LCD, its color reproduction rate is 30% higher, and the contrast ratio is even 20 times better. The image afterimage phenomenon, which is the biggest shortcoming of LCD, cannot be found in AMOLED. This is because, contrary to LCD, the backlight uses indirect light sources through liquid crystals, color filters, etc. For complex picture displays, AMOLED directly reproduces natural-color pictures through the organic material's own light emission. In addition, compared with LCD, OLED has a very simple structure, so it is also very advantageous on the side of components.

However, when looking at the original price of OLED materials, driving circuits, and driving IC prices, the depreciation rate of OLED is unexpectedly large, accounting for half of the total cost. This is because OLED has not yet been popularized among consumers, making it difficult to achieve the effect of reducing production costs through mass production.

Because of this practical problem, white light OLED technology has become a recently emerging display technology. A brief description of white OLED is a technology that combines the advantages of LCD panels with the advantages of AMOLED panels.

That is, a white light OLED and TFT with switching function are placed on the R/G/B primary color filter that displays the color, and the self-luminous white light OLED is switched to a TFT to display the display technology of the R/G/B primary color filter.

If this white OLED panel can be enlarged, it can provide a popular high-quality display panel with LCD-level mass production yield comparable to that of AMOLED.

However, the current reality is that there is no technology that can mass-produce white OLED panels of 40 inches or more that appear in popular LCDs or PDPs, or 8th generation or more. Therefore, it is far away to popularize high-quality display panels.

It is true that large-sized coils can be realized in a single sheet, but the reason why it is difficult to increase the size of a mask formed on a single sheet is that the coil supply size of the mask raw material is not produced in the size required for enlargement. That is, because of profitability issues, coil manufacturers will not produce coils of the size required by white light OLED display manufacturers.

In addition, in order to produce a large number of white OLED panels of the fourth generation or above, if the mask frame assembly technology for white OLEDs with high definition and white OLEDs can be deposited at the same time, it can overcome the yield problem and achieve mass production. Most of the fabrication techniques or equipment of mask frame components are for the production of LCD or AMOLED panels, so it is difficult to be directly applied as a mask frame component for white OLED.

The specific reason is that in the manufacturing method or manufacturing equipment of the mask frame assembly for AMOLED that has formed a large-scale LCD or is currently developing a large-scale technology, such as FMM Type OLED, in order to deposit organic substances for R/G/B, it is used in A metal mask (Fine Metal MASK) corresponding to dense grooves is formed in each pixel, and Metal is deposited and packaged using an open mask. But white OLED is different. In order to correspond to R/G/B colors, the color filter used in the LCD manufacturing process is used. Therefore, open masks are used in the White organic deposition, metal deposition and packaging processes. Therefore, there is no need to apply a metal mask. When the open mask is fabricated on multiple sides within a single sheet, it will be difficult to apply due to the limitation of the Mask Coil Size.

In addition, as shown in Figure 11, it is difficult to maintain the tension and place the mask precisely without falling down in the conventional way of making multiple sides inside a single sheet. Therefore, it is difficult to produce a large area of white light. Mask frame assembly for OLED.

That is, if the mask does not have tension, the center of the mask will sag due to insufficient positioning, which will affect the shadow (Shadow) and deposition position. Therefore, it is impossible to provide a high-definition white OLED panel, and there is a problem of lower yield. .
