Abstract
Description
本發明係關於一種可撓式顯示面板及其封裝方法，尤指一種利用多次封裝形成之可撓式顯示面板及其封裝方法。The present invention relates to a flexible display panel and a packaging method thereof, and more particularly to a flexible display panel formed by using multiple packages and a packaging method thereof.
顯示面板對於阻水氧能力具有一定的要求，例如有機發光二極體(OLED)顯示面板的水氣穿透率(WVTR)必須達到10-6g/m2-day。對於硬式有機發光二極體顯示面板而言，由於其係利用兩片玻璃基板進行封裝，因此可輕易達到水氣穿透率的規格要求。然而，對於可撓式有機發光二極體顯示面板而言，由於其係使用可撓式薄膜材料來進行封裝，因此常面臨無法達到水氣穿透率的規格要求的難題，而造成可撓式顯示面板在發展上的一大限制。The display panel has certain requirements for water-blocking oxygen resistance. For example, the water vapor transmission rate (WVTR) of an organic light-emitting diode (OLED) display panel must reach 10 -6 g/m 2 -day. For the hard organic light-emitting diode display panel, since it is packaged by using two glass substrates, the specification of water vapor permeability can be easily achieved. However, for a flexible organic light-emitting diode display panel, since it is packaged using a flexible film material, it is often faced with a problem that the specification of water vapor transmission rate cannot be achieved, and the flexible type is caused. A major limitation in the development of display panels.

請參考第10圖。第10圖繪示了本發明之第五較佳實施例之一變化實施例之可撓式顯示面板的封裝示意圖。如第10圖所示，本變化實施例之可撓式顯示面板的封裝方法另包括於第一黏著層18、第一阻水氧薄膜16、顯示陣列14、可撓式基板12與第二黏著層22之側邊形成一封膠層28，以製作出一可撓式顯示面板5’。不同於第五較佳實施例之處在於，在本變化實施例中，第二阻水氧薄膜20大體上係切齊或內縮於第一黏著層18、第一阻水氧薄膜16、顯示陣列14、可撓式基板12與第二黏著層22。例如，第二阻水氧薄膜20可切齊第一黏著層18，而可相對於第一阻水氧薄膜16、顯示陣列14、可撓式基板12與第二黏著層22內縮，但不以此為限。此外，第三阻水氧薄膜24則係大體上突出於第二阻水氧薄膜20、第一黏著層18、第一阻水氧薄膜16、顯示陣列14、可撓式基板12與第二黏著層22。封膠層28係位於第二阻水氧薄膜20、第一黏著層18、第一阻水氧薄膜16、顯示陣列14、可撓式基板12與第二黏著層22之側邊，且封裝層28係位於第三阻水氧薄膜24上。Please refer to Figure 10. FIG. 10 is a schematic diagram showing the packaging of a flexible display panel according to a variation of the fifth preferred embodiment of the present invention. As shown in FIG. 10, the packaging method of the flexible display panel of the modified embodiment further includes a first adhesive layer 18, a first water-blocking oxygen film 16, a display array 14, a flexible substrate 12 and a second adhesive. A layer of glue 28 is formed on the side of the layer 22 to form a flexible display panel 5'. Different from the fifth preferred embodiment, in the modified embodiment, the second water-blocking oxygen film 20 is substantially cut or contracted to the first adhesive layer 18, the first water-blocking oxygen film 16, and the display. The array 14, the flexible substrate 12 and the second adhesive layer 22. For example, the second water blocking oxygen film 20 can be aligned with the first adhesive layer 18, and can be retracted relative to the first water blocking oxygen film 16, the display array 14, the flexible substrate 12 and the second adhesive layer 22, but not This is limited to this. In addition, the third water blocking oxygen film 24 is substantially protruded from the second water blocking oxygen film 20, the first adhesive layer 18, the first water blocking oxygen film 16, the display array 14, the flexible substrate 12 and the second adhesive. Layer 22. The sealing layer 28 is located on the side of the second water blocking oxygen film 20, the first adhesive layer 18, the first water blocking oxygen film 16, the display array 14, the flexible substrate 12 and the second adhesive layer 22, and the encapsulation layer The 28 series is located on the third water blocking oxygen film 24.
綜上所述，本發明之可撓式顯示面板的封裝方法利用多次封裝形成多層阻水氧薄膜，可有效將可撓式顯示面板的阻水氧能力提升，以符合可撓式顯示面板的水氧穿透率的規格，例如達到10-6g/m2-day。此外，由於本發明之可撓式顯示面板的阻水氧能力係由至少兩層阻水氧薄膜提供，對於任一層阻水氧薄膜而言，其僅需提供部分的阻水氧能力，因此技術瓶頸較低而可大量生產。In summary, the packaging method of the flexible display panel of the present invention utilizes multiple packages to form a multi-layer water blocking oxygen film, which can effectively improve the water blocking oxygen resistance of the flexible display panel to conform to the flexible display panel. The specification of the water oxygen permeability is, for example, 10 -6 g/m 2 -day. In addition, since the water-blocking oxygen resistance of the flexible display panel of the present invention is provided by at least two layers of water-blocking oxygen film, for any layer of water-blocking oxygen film, it only needs to provide partial water-blocking oxygen capability, so the technology The bottleneck is low and can be mass produced.
