Abstract

A flexible circuit film including a first flexible film, a second flexible film facing the first flexible film, and a plurality of wirings arranged between the first flexible film and the second flexible film. Each of the wirings has a first portion extending in a second direction from a first terminal portion to a first connection part, a second portion extending in a first direction different from the second direction from the first connection part to a second connection part, and a third portion extending in a direction opposite to the second direction from the second connection part to a second terminal portion.

Claims (29)

1. A display apparatus, comprising:

a display panel; and

a driver comprising a plurality of printed circuit boards and a flexible circuit film electrically connecting the printed circuit boards, the driver being configured to apply electrical signals to the display panel,

wherein:

the flexible circuit film comprises:

a first flexible film;

a second flexible film facing the first flexible film; and

a plurality of wirings arranged between the first flexible film and the second flexible film; and

each of the wirings has a first portion extending in a second direction from a first terminal portion to a first connection part, a second portion extending in a first direction different from the second direction from the first connection part to a second connection part, and a third portion extending in a direction opposite to the second direction from the second connection part to a second terminal portion.

2. The display apparatus of claim 1 , wherein the second flexible film further comprises a protective portion extending in an arranging direction of the wirings and partially covering the one of the first and second terminal portions of the wirings.

3. The display apparatus of claim 1 , wherein the first and second flexible films have a U-shape that includes a base portion that corresponds to the second portions of the wirings that extend in the first direction and two branches extending from opposite ends of the base portion and corresponding to the first and third portions of the wirings extending in the second direction and the direction opposite to the first direction, respectively, the first and second flexible films comprising an inner edge having two inner corners that correspond to an inner portion of the U-shape where the branches meet the base portion.

4. The display apparatus of claim 1 , wherein each of the wirings comprises a straight line portion.

5. The display apparatus of claim 1 , each of the wirings comprises a curved line portion.

6. The display apparatus of claim 1 , wherein:

the printed circuit boards comprises a first printed circuit board and a second printed circuit board disposed adjacent to each other in the second direction;

the driver further comprises a host line connected to a center portion of the second printed circuit board configured to transfer externally provided electrical signals to the second printed circuit board; and

the flexible circuit film is connected to edge portions of the first and second printed circuit boards.

7. A display apparatus, comprising:

a display panel; and

a driver comprising a plurality of printed circuit boards and a flexible circuit film electrically connecting the printed circuit boards, the driver being configured to apply electrical signals to the display panel,

wherein the flexible circuit film has a substantially U-shape and comprises:

a first flexible film;

a second flexible film facing the first flexible film; and

a plurality of wirings arranged between the first flexible film and the second flexible film.

8. The display apparatus of claim 7 , wherein each of the wirings comprises a straight line portion.

9. The display apparatus of claim 7 , wherein:

the printed circuit boards comprises a first printed circuit board and a second printed circuit board disposed adjacent to each other along a side of the display panel;

the driver further comprises a host line connected to a center portion of the second printed circuit board configured to transfer externally provided electrical signals to the second printed circuit board; and

the flexible circuit film is connected to edge portions of the first and second printed circuit boards.
