DRIVER IC AND IMAGE DISPLAY DEVICE

摘要

The driver IC used to activate a display panel has a free region which is proactively provided therein so as to separate its external connection terminals from an edge side thereof by a distance representing at least one row of the terminals. In mounting the driver IC on a display panel by COG technique, the driver IC may be COG-mounted so that bent parts of lead-out lines led out from the display panel and bent at a midway along their lengths to have a narrowed pitch are in position to overlie the free region. The same effect as achieved by reducing the size of the short side of the driver IC by the size of the free region can be obtained. According to the invention, the reduction in frame size of an image-display panel can be readily realized without the need for reducing the chip size of a driver IC.

主权项

1. An image display device comprising:
an image-display panel having a TFT array substrate with TFTs and pixel electrodes arranged like a matrix; and a driver IC mounted on the TFT array substrate of the image-display panel according to COG technique, wherein drive-side mount lines and host-side mount lines are each led to where the driver IC is COG-mounted on the TFT array substrate and bent at a midway along their lengths, whereby their line pitches are reduced, the driver IC has, in plane view, an appearance of a rectangular form, and has a row of first external connection terminals close to a first edge side corresponding to one of a pair of long sides of the rectangular form extending along a longitudinal direction thereof, and which are connected with the drive-side mount lines, and a row of second external connection terminals close to a second edge side corresponding to the other long side of the rectangular form, and connected with the host-side mount lines, and bent parts where the drive-side mount lines are bent are formed in position so as to partially overlie a free region between the first edge side and the row of first external connection terminals.
