AI Technical Summary

Benefits of technology

The single FPC board design streamlines the assembly process, reduces manufacturing waste, and lowers production costs by eliminating the need for a second FPC board, while maintaining the thinness and flexibility required for touch sensitive display modules.

Problems solved by technology

Since two FPC boards are used, more cost will be incurred and more wastes will be generated in the manufacturing process.

first embodiment

[0022]Referring to FIGS. 3A-3C and 4. FIGS. 3A-3C show assembly structural diagrams of a touch sensitive display module according to one embodiment of the invention. FIG. 4 shows a schematic diagram of a single FPC board for connecting multiple modules according to one embodiment of the invention. The touch sensitive display module 200 includes a first module 210, a second module 220, a third module 230 and a single FPC board 240. The single FPC board 240 connects the first module 210, the second module 220 and the third module 230. The first module 210 is such as a display panel. The second module 220, such as a touch panel, is disposed on the first module 210. The third module 230, such as a motherboard, is adjacent to the first module 210. Preferably, the first module 210 is disposed between the second module 220 and the third module 230. In one embodiment, the touch panel can be pasted on a lower surface (as indicated in FIG. 3A) of the cover 250 according to an out cell solutio...

second embodiment

[0027]Referring to FIGS. 6A-6C and 7A-7B. FIGS. 6A-6C respectively show assembly structural diagrams of a touch sensitive display module according to one embodiment of the invention. FIGS. 7A and 7B respectively show schematic diagram of a single FPC board for connecting multiple modules according to one embodiment of the invention. The touch sensitive display module 300 includes a first module 310, a second module 320, a third module 330 and a single FPC board 340. The first module 310 is such as a display panel. The second module 320 is such as a touch panel. The third module 330 is such as a motherboard. In one embodiment, the touch panel can be pasted on a lower surface (as indicated in FIG. 6A) of the cover 350 according to an out cell solution; a touch-sensitive transparent conductive layer 322 (as indicated in FIG. 6B) can be formed on the cover 250 according to a one glass solution; or the touch-sensitive transparent conductive layer 322 can be integrated onto the display pa...

third embodiment

[0033]FIGS. 9A-9B respectively show schematic diagrams of a single FPC board for connecting multiple modules according to one embodiment of the invention. The single FPC board 440 has a single thin film 441. The thin film 441 has a first module connecting portion 442, a second module connecting portion 444, a third module connecting portion 446, a first slot S1 and a second slot S2. The present embodiment is similar to the second embodiment, and the main differences are as follows: the first slot S1 and the second slot S2 are located on the same side of the thin film 441, and the second module connecting portion 444 is located between the first slot S1 and the second slot S2.

[0034]Based on the source of the signal, the first module connecting portion 442 is divided into a first signal connecting portion 442a and a second signal connecting portion 442b according to the source of the signal. The first slot S1 separates the first signal connecting portion 442a and the second module con...

Abstract

A single flexible printed circuit (FPC) board for connecting multiple modules including a thin film is provided. The thin film has a first module connecting portion, a second module connecting portion and a third module connecting portion. The first module connecting portion is located on a first side of the thin film. The second module connecting portion and the third module connecting portion are located on a second side of the thin film. The first side is opposite to the second side. At least one first line is disposed between the first module connecting portion and the second module connecting portion. At least one second line is disposed between the first module connecting portion and the third module connecting portion.

Description

[0001]This application is a continuation of U.S. patent application Ser. No. 13 / 438,636, filed Apr. 3, 2012. This application claims the benefits of U.S. provisional application Ser. No. 61 / 497,505, filed Jun. 15, 2011 and Taiwan application Serial No. 100129439, filed Aug. 17, 2011, the subject matters of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates in general to a flexible printed circuit (FPC) board, and more particularly to a single FPC board for connecting multiple modules and a touch sensitive display module using the same.[0004]2. Description of the Related Art[0005]Touch panels have now been widely used in various electronic products. Particularly, most display panels are equipped with a touch panel for allowing users to click or press the screen with a finger or a stylus. For example, the resistive touch panel detects the coordinates of the touch point by sensing voltage drop, and the capaci...
