  • SUBSTRATE BONDING APPARATUS AND SUBSTRATE BONDING METHOD
    Publication number: 20130319597
    Abstract: A substrate bonding apparatus includes a vacuum chamber having a bonding space where a first substrate and a second substrates are bonded together, a first pump for sucking air of the bonding space at a first intensity, a second pump for sucking the air of the bonding space at a second intensity greater than the first intensity, a nitrogen supply for supplying nitrogen to the bonding space, a sensor for sensing the pressure of the bonding space; and a controller for controlling the first pump, the second pump, and the nitrogen supply.

  • Display device with reflective surface for reflecting light to edges of display area
    Patent number: 7682061
    Abstract: A display device is provided. The display device includes a display panel comprising a display surface configured to display an image thereon, the display surface having an edge; a light source spaced apart from the display panel to form a space therebetween and configured to emit light to the display panel, wherein the display panel is configured to generate image on the display surface using the light from the light source; and a reflective surface arranged so as to reflect light emitted from the light source and to direct the reflected light to the edge.
