Abstract
A tape circuit substrate includes a base film with first wiring and second wiring disposed on the base film. The first wiring extends into a chip mount portion through a first side and bends within the chip mount portion toward a second side. The second wiring extends into the chip mount portion through a third side and bends within the chip mount portion toward the second side. The first, second, and third sides are different sides of the chip mount portion. Thus, size and in turn cost of the base film are minimized by arranging wirings within the chip mount portion for further miniaturization of electronic devices, such as a display panel assembly, using the tape circuit substrate.
Claims9
A semiconductor chip package comprising:
- a tape circuit substrate with an integrated circuit mounted over a chip mount portion, the tape circuit substrate including:
- a base film;
- a first wiring, disposed on the base film, that extends into the chip mount portion through a first side and that bends within the chip mount portion toward a second side, wherein the first wiring ends at a first pad of the integrated circuit, and wherein the first pad is disposed toward the second side within the chip mount portion;
- a second wiring, disposed on the base film, that extends into the chip mount portion through a third side and that bends within the chip mount portion toward the second side, wherein the second wiring ends at a second pad of the integrated circuit, and wherein the second pad is disposed toward the second side within the chip mount portion,
- wherein the first, second, and third sides are different sides of the chip mount portion;
- and
- bypass wiring, disposed on the base film, that extends parallel to the second side when the bypass wiring is disposed in one of outside of or within the chip mount portion;
- and
- a semiconductor chip mounted over the chip mount portion and having electrode pads coupled to the first and second wirings, wherein the first and second wirings and the semiconductor chip are formed above a same surface of the base film, and wherein the integrated circuit is mounted directly on the base film without another base film being disposed between the integrated circuit and said base film having the integrated circuit directly mounted thereon;
- wherein the bypass wiring is disconnected from the semiconductor chip.
The semiconductor chip package 1, wherein the semiconductor chip is a display panel driver chip, and wherein the first and second wirings couple the display panel driver chip to electrode terminals of a display panel.
A display panel assembly comprising:
- a display panel having electrode terminals along an edge, and displaying information by receiving driving signals via the electrode terminals;
- and
- a semiconductor chip package comprising:
- a tape circuit substrate with an integrated circuit mounted over a chip mount portion, the tape circuit substrate including:
- a base film;
- a first wiring, disposed on the base film, that extends into the chip mount portion through a first side and that bends within the chip mount portion toward a second side, wherein the first wiring ends at a first pad of the integrated circuit, and wherein the first pad is disposed toward the second side within the chip mount portion;
- a second wiring, disposed on the base film, that extends into the chip mount portion through a third side and that bends within the chip mount portion toward the second side, wherein the first wiring ends at a first pad of the integrated circuit, and wherein the first pad is disposed toward the second side within the chip mount portion, and wherein the first, second, and third sides are different sides of the chip mount portion;
- and
- bypass wiring, disposed on the base film, that extends parallel to the second side when the bypass wiring is disposed in one of outside of or within the chip mount portion;
- and
- a display panel driver chip mounted over the chip mount portion for generating the driving signals,
- wherein the first and second wirings couple electrode pads of the display panel driver chip to the electrode terminals of the display panel;
- and wherein the first and second wirings and the integrated circuit are formed above a same surface of the base film;
- and wherein the integrated circuit is mounted directly on the base film without another base film being disposed between the integrated circuit and said base film having the integrated circuit directly mounted thereon;
- and wherein the bypass wiring is disconnected from the display panel driver chip.
