  • Patent number: 9823518
    Abstract: A display device and an electronic device including the same are provided. The electronic device includes a display, a window, and a bonding member. The display includes a plurality of sides. The window includes an internal area of an inside coupled with the plurality of sides and an external area of an outside of the internal area. The bonding member includes an air path formed in the plurality of sides and at least a partial area of the external area, and adapted to a flow of air between the internal area and an external area of the display in at least a part coupled with the plurality of sides.
    Type: Grant

  • Patent number: 9036111
    Abstract: A Liquid Crystal Display (LCD) module for preventing a hot spot that deteriorates an external appearance quality using existing components is provided. The LCD module includes an optical sheet disposed at an upper surface of a light guide plate, a Light Emitting Diode Flexible Printed Circuit Board (LED FPCB) on which an LED for emitting light to the light guide plate is mounted, and a double-sided tape having a portion protruding toward the optical sheet further than the LED FPCB and adhered to a mounting surface of the LED FPCB. Therefore, occurrence of a hot spot can be reduced without increasing components. Further, because a thickness increase of a local portion is unnecessary, a second failure such as panel lifting is not caused.

  • Patent number: 8666061
    Abstract: A mobile device is provided. The mobile device includes a panel assembly, a cover window and an adhesive tape. The panel assembly displays images and the cover window is mounted onto the panel assembly. The cover window protects the panel assembly and detects touches that occur thereon. The adhesive tape forms an open hole at the central portion to separate the cover window and the panel assembly. The adhesive tape adheres the cover window to the edge portion of the panel assembly. The adhesive tape further includes an air path part that provides an air passage for communicating an air chamber with the open hole. The air chamber fills with air. The mobile device can display images without a pooling phenomenon, and reduce the chance of malfunction when the user touches the panel assembly via the cover window.
