  • Connection structures of wiring board and connection structure of liquid crystal display panel
    Patent number: 7339646
    Abstract: A liquid crystal display device of the present invention comprises a liquid crystal display panel (1) provided with one or more electrode terminals (R1) to (Rn) and a pair of reference markers (N1) on a non-display region (3) thereof, a flexible printed circuit board (FPC1) provided with alignment markers (M2) corresponding to the reference markers, and a printed circuit board (PCB1) having one or more electrode terminals (T1) to (Tn), the reference markers being located inward relative to the alignment markers and the electrode terminals of the liquid crystal display panel and the electrode terminals of the printed circuit board being connected to each other through wiring (P1) to (Pn) of the flexible printed circuit board, wherein the alignment markers are elongated holes having long axes at least in one direction.

  • Liquid crystal display and its inspecting method
    Patent number: 6407795
    Abstract: A liquid crystal panel (1) includes plural signal lines and scanning lines disposed in matrix, and liquid-crystal-driving LSIs (5, 6) having input and output portions directly connected by thermocompression bonding with an anisotropically conductive adhesive (9). The LSIs are mounted on a conductor on a rim of the panel. Film jumper boards (10, 14), the respective numbers of which correspond to the number of the driving LSIs (5, 6), connects between a terminal conductor (21) at the rim of the liquid crystal panel (1) and circuit boards (12, 16). As a result, a liquid crystal display which can be designed freely, can be modified easily, can employs common components, and can have a defective driving LSI specified and repaired readily and accurately is provided. A method of inspecting the display is also provided.
