  • Publication number: 20080311785
    Abstract: A connector that is capable of reducing defects in display apparatuses is presented. The connector includes a body, a plurality of terminals and a cover. The body has a base and a sidewall. The terminals are disposed on the body and arranged to make an electrical connection with the electrical circuit when the electrical circuit is received by the body. The cover includes a rotation axis, a fixing portion extending from the rotation axis such that the fixing portion is substantially parallel to the base of the body, and a protrusion portion protruding from the rotation axis substantially perpendicularly to the base of the body. The connector prevents electrical discharge from the flexible printed circuit board to the electrical circuit and prevents physical damage to the electrical circuit. Therefore, defect rate decreases and a yield of a display apparatus increases.

  • Publication number: 20070157487
    Abstract: An LCD includes a liquid crystal panel, a backlight unit, a rear cover, a mold frame and a front cover that slides down over and couples with the rear cover to form a space within which the liquid crystal panel, mold frame and backlight unit are protectively enclosed. The front cover has a lateral part with a first coupling part and a feature for receiving a lateral projection on the mold frame. The rear cover has a mold frame lateral wall with a second coupling part adapted to slidably engage and couple with the first coupling part when the front cover is slid down on the rear cover, and the mold frame has a lateral projection that is received in the front cover receiving feature when the front and rear covers are fully assembled together. The foregoing features enable deformation of the lower cover to be minimized during assembly of the device.
