  • Patent number: 7119562
    Abstract: A contact-type film probe including a plastic substrate and multiple signal lines arranged on one face of the substrate. A contact conductive layer is disposed at one end of each signal line. A buffer layer is disposed between the contact conductive layer and the substrate. The other section of the signal line free from the contact conductive layer is coated with an insulating layer. By means of the buffer layer, when contacting with the wires of the liquid crystal display, the force is fully evenly exerted onto the contact conductive layers and the direct contact force exerted onto the contact conductive layers is reduced so as to prolong the using life of the contact-type film probe.

  • Patent number: 7113324
    Abstract: An image display apparatus is capable of recycling the “OFF” state light to increase the image brightness and contrast. The image display apparatus includes a light source, a spatial light modulator, a total internal reflection (TIR) prism, a projection lens set, and a reflector. The spatial light modulator selectively modulates a light beam from the light source to a first path to form a first path light beam or to a second path to form a second path light beam. The TIR prism disposed between the light source and the spatial light modulator is configured to allow the light beam to travel therethrough in a first direction and to be incident on the spatial light modulator. The projection lens set disposed between the modulator and a screen is configured to project the first path light beam to form an image on a screen. The reflector is configured to reflect the second path light beam to form a reflected light beam that is incident on the TIR prism in a second direction as a recaptured light beam.
