The present invention relates to an integrated circuit chip, in particular to an integrated integrated circuit chip for an integrated panel.

Figure 1 schematically shows a conventional integrated panel. This panel 10 can integrate touch into a display panel. Touch electrodes (not shown) can be formed on the pixel unit 11, so that display and touch sensing can be realized. Function. The scan lines for displaying RGB sub-pixels extend along the X axis and are connected to display scan drive circuits 13L, 13R. The display scan drive circuits 13R, 13L can be independent drive chips or circuits integrated in the panel, and accept The timing control signal sent from an integrated integrated circuit chip 15. In FIG. 1, the signal line extending along the Y axis has a display data line 121, and the display data line 121 is used to write display data. The three display data lines 121 can be connected to a multiplexer 17 and then to the outer lead bonding pad (OLB pad) 151 of the integrated integrated circuit chip 15.

As shown in FIG. 1, the size of the integrated integrated circuit chip 15 in the X-axis direction is significantly smaller than that of the display active area 101 of the integrated panel 10. Therefore, the display data line 121 of the display active area 101 must be retracted. It is connected to the outer pins 151 of the integrated integrated circuit chip 15, and the size of the area required for the wire take-up is limited by the minimum line width and line spacing of the display panel manufacturing process.

In particular, mobile phone products require a higher screen-to-body ratio to improve the appearance of the product. Therefore, reducing the border area 102 becomes a very important product specification. However, the conventional pin design of the integrated integrated circuit chip 15 is that all the outer pins 151 are arranged on the side of the integrated integrated circuit chip 15 close to the display active area 101. With this pin design, due to the need for wire take-up The area is so large that the boundary area 102 cannot be reduced.

In the above embodiment, the two ends of the outer pin row are respectively arranged on the surface adjacent to the connection of the first short side and the first long side and the surface adjacent to the connection of the second short side and the first long side. However, in In other embodiments, the two ends of the outer pin row can also extend slightly away from the first long side and toward the second long side, so that the area near the two short sides can be effectively used to achieve circuit routing. The required area and the integrated integrated circuit chip overlap to the maximum, so the boundary area can be effectively reduced and narrowed, thereby meeting the demand for high screen-to-body ratio of the display panel.

FIG. 6 schematically shows the mobile device including an integrated integrated circuit chip of the present invention, where the mobile device is, for example, a mobile phone 61.
