  • Patent number: 8253692
    Abstract: A top-emitting OLED display having a transparent touch panel includes a substrate, an upper cover plate, an OLED display device, a capacitive touch device and a sealant layer. The OLED device is stacked on the substrate, the capacitive touch device is stacked on the upper cover plate, and the sealant layer combines the substrate and the upper cover plate such that the OLED device and the capacitive touch device are enclosed between the substrate and the upper cover plate. The capacitive touch device includes a first transparent conductive layer, an isolating layer, a second transparent conductive layer and an electromagnetic shielding layer sequentially formed on the upper cover plate. The electromagnetic shielding layer can effectively reduce the electromagnetic interfering between the OLED device and the capacitive touch device.

  • Publication number: 20070242054
    Abstract: A light transmission touch panel comprises a transparent substrate, a first transparent conductive layer, an insulation layer and a second transparent conductive layer, wherein the first transparent conductive layer, the insulation layer and the second transparent conductive layer are patterned and overlaid on a surface of the substrate. The first transparent conductive layer and the second transparent conductive layer are either on a surface or respectively on two opposite surfaces of the insulation layer. An electrical field having a component along the surface of the substrate occurs between two adjacent portions of the first transparent conductive layer and the second transparent conductive layer once they are electrically charged. When an article touches the touch panel, the intensity of the electrical lines is accordingly changed so that the touch panel can detect where the touch position is.

  • Publication number: 20060156972
    Abstract: An organic light-emitting panel, a process for packaging an organic light-emitting panel and a coating apparatus applied thereto are described. A patterned desiccant with large surface area is formed on a cover plate by an ink-jet printing process. The process for packaging an organic light-emitting panel and the coating process are applied for reducing crosslinking time of the desiccant, increasing the surface area of the desiccant and enhancing the moisture absorption ability of the desiccant.

  • Patent number: 6764369
    Abstract: Mass production encapsulation equipment and method for mass production of organic light emitting display devices, having a transporting system, a panel supply system, multiple dispensing systems, turning/storage system, cover plate supply system, lamination/ultra-violet radiation system, and an ultra-violet radiation system. The above systems are linked via the transmission system. Being supplied by the panel supply system, a panel is transported to the turning/storage system for turning over. The panel is then transported into alternate dispensing systems for resin coating. The panel coated with resin is again transported to the turning/storage system for storage. The first exposure stage is performed by an aligning lamination performed on the panel and a cover plate supplied by the cover plate supply system in the lamination/ultra-violet radiation system. The second exposure stage is further performed to cure the resin in the ultra-violet radiation system.
