Display apparatus

USPTO Application #: 20050285836
Title: Display apparatus
Abstract: A display apparatus including a display panel including a pixel electrode and a plurality of first signal lines transmitting a driving signal to the pixel electrode, a conductive member on the first signal lines, the conductive member having a resin, and a second signal line on the conductive member, the second signal line having an opening through which the resin travels to couple the second signal line with one of the first signal lines.

CROSS REFERENCE TO RELATED APPLICATION

[0001] The present application claims priority from Korean Patent Application No. 2004-46930, filed on Jun. 23, 2004, which is hereby incorporated by reference for all purposes as if fully set forth herein.

BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates to a display apparatus, particularly, the present invention relates to a display apparatus capable of improving an image display quality.

[0004] 2. Description of the Related Art

[0005] A display apparatus displays an image based on data of an electric signal that is processed by an information processing apparatus. The display apparatus may include a liquid crystal display (DCD), an organic light emitting display (OLED), or the like.

[0006] A liquid crystal display (LCD) apparatus displays an image using a liquid crystal, which has electronic and optical characteristics. The LCD apparatus includes a display panel assembly and a backlight assembly. The display panel assembly controls the liquid crystal. The backlight assembly supplies the display panel assembly with a light.

[0007] The display panel assembly includes a display panel, a chip on film (COF), and an anisotropic conductive film (ACF). The display panel has the liquid crystal, and a plurality of signal lines. The COF includes a plurality of signal lines transmitting a driving signal to the display panel. The signal lines of the COF and the signal lines of the display panel are coupled via the ACF film.

[0008] The ACF film includes a resin having conductive particles. The ACF film is provided between the signal lines of the COF and the signal lines of the display panel.

[0009] The ACF film is heated and compressed so that the signal lines of the COF are coupled with the signal lines of the display panel through the conductive particles of the ACF film resin.

[0010] However, when portions of the signal lines increase, the resin may not be sufficiently ejected from a space between the signal lines of the display panel and the signal lines of the COF and the conductive particles may not contact the signal lines. Therefore, the signal lines of the display panel may be disconnected from the signal lines of the COF.

SUMMARY OF THE INVENTION

[0011] The present invention provides a display apparatus capable of improving an image display quality.

[0012] Additional features of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of the invention.

[0013] The present invention discloses a display apparatus including a display panel including a pixel and a plurality of first signal lines transmitting a driving signal to the pixel electrode, a conductive member on the first signal lines, the conductive member having a resin, and a second signal line on the conductive member, the second signal line having an opening through which the resin travels to couple the second signal line with one of the first signal lines.

[0014] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention.

[0016] FIG. 1 is a partially cut out perspective view showing a display apparatus according to an embodiment of the invention.

[0017] FIG. 2 is a cross-sectional view taken along a line I.sub.1-I.sub.2 of FIG. 1.

[0018] FIG. 3 is a plan view showing a portion `A` of FIG. 1.

[0019] FIG. 4 is a plan view showing a display apparatus according to an embodiment of the invention.

[0020] FIG. 5 is a plan view showing timing signal lines, driving signal lines, and gate signal lines of FIG. 4.
