Abstract
In a multi-panel display device in which plural individual display devices are joined, it is possible to guarantee image continuity in panel junction areas of the multi-panel display device by disposing a frame-type optical member, which includes a frame section having plural optical fibers and a central light-transmitting area, on the front surface of the multi-panel display device and optimizing structures of an inner inclined surface of the frame section of the frame-type optical member and optical fibers included in the frame section.
Claims20
A multi-panel display device, comprising:
- a plurality of adjoining individual display devices;
- and
- an optical member on the plurality of individual display devices, the optical member comprising:
- a frame section covering junction areas of the individual display devices where images are not displayed and portions of display areas of the individual display devices adjacent to the junction areas, the frame section comprising a plurality of light conduits, and the frame section comprising:
- a bottom surface facing a display area of an individual display device, and
- a top surface facing away from the display area of the individual display device, the top surface parallel to the bottom surface;
- and
- a viewing angle increasing plate on the frame section of the optical member at a side of the frame section opposite to the plurality of adjoining individual display devices, the viewing angle increasing plate configured to receive first light with a first viewing angle from the light conduits at a first side facing the light conduits and transmit second light of a second viewing angle larger than the first viewing angle from a second side facing away from the light conduits, the viewing angle increasing plate comprising a plurality of light conduits, wherein a diameter of the light conduits of the viewing angle increasing plate is different from a diameter of the light conduits of the frame section.
An optical member for multi-panel display device, comprising:
- a first frame section covering junction areas of first and second individual display devices where images are not displayed and portions of display areas of the first and second individual display devices adjacent to the junction areas, the first frame section comprising a plurality of light conduits, and the frame section comprising:
- a bottom surface facing a display area of the first individual display device, and
- a top surface facing away from the display area of the first individual display device, the top surface parallel to the bottom surface;
- and
- a viewing angle increasing plate on the frame section of the optical member at a side of the frame section opposite to the plurality of adjoining individual display devices, the viewing angle increasing plate configured to receive first light with a first viewing angle from the light conduits at a first side facing the light conduits and transmit second light of a second viewing angle larger than the first viewing angle from a second side facing away from the light conduits, the viewing angle increasing plate comprising a plurality of light conduits, wherein a diameter of the light conduits of the viewing angle increasing plate is different from a diameter of the light conduits of the frame section.
