  • Publication number: 20060187680
    Abstract: A system comprising a notebook computer, a back light module and a light guide plate. The notebook computer mainly comprises a host machine and a liquid crystal display hinged to that. The liquid crystal display further comprises a liquid crystal display panel and a back light module disposed underneath that. The back light module mainly comprises a plastic frame and a light guide plate. The plastic frame has a first contact surface and the light guide plate has at least a protruding ear with a second contact surface. The light guide plate is clamped within a plastic frame through the protruding ear. Because the contact between the first contact surface of the plastic frame and the second contact surface of the protruding ear is either a line contact or a point contact, the noise produced by friction between two when the liquid crystal display is lifted or shut is minimized.
