Abstract
A technology is provided for suppressing the occurrence of problems due to positional shift caused by temperature increase of a panel and a chassis, in a structure for mounting a driver IC chip and a driver module in a flat display device. The plasma display device is provided with a chassis section (63) arranged close to a panel (PDP) (64) and a rear surface side thereof; and a WB-ADM (address driver module) (61) having a flexible substrate (41) whereupon the driver IC chip (in a sealing resin (45)) for driving an electrode of the panel (64) is mounted by WB (wire bonding) method. The plasma display device is also provided with a buffer member (62) attached to the chassis section (63) to have a sliding mechanism and for fixing the WB-ADM (61).
Claims20
A flat display device comprising:
- a flat display panel having an electrode;
- a driver module having a driver IC chip connected to the electrode of the flat display panel to drive the electrode and a flexible substrate having the driver IC chip mounted thereon;
- a chassis section provided near a rear surface side of the flat display panel;
- and
- a buffer member attached so as to be movable with respect to the chassis section,
- wherein the driver module is fixed to the buffer member.
A flat display device comprising:
- a flat display panel having an electrode;
- a driver module having a driver IC chip connected to the electrode of the flat display panel to drive the electrode and a flexible substrate having the driver IC chip mounted thereon;
- a chassis section provided near a rear surface side of the flat display panel;
- a holding plate holding the driver module by applying a pressing force to the driver module by a direct or indirect combination with the chassis section;
- and
- a buffer member formed separately from the chassis section and the holding plate,
- wherein the buffer member is disposed near a non-circuit-formation surface of the driver IC chip.
