[0065] Figure 9A ~ Figure 9B Schematic diagrams of single-chip flexible circuit boards connected to multiple modules according to two embodiments of the present invention are respectively shown. The one-piece flexible circuit board 440 has a single film 441 . The 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 . These two embodiments are similar to the second embodiment, the main difference is that the first slot S1 and the second slot S2 are located on the same side of the film 441, and the second module connecting portion 444 is located between the first slot S1 and the second slot. between slots S2.

[0066] In these two embodiments, the first module connection part 442 is divided into a first signal connection part 442 a and a second signal connection part 442 b according to different signal sources. Wherein, the first slot S1 is separated between th...

Abstract

The invention discloses a single flexible printed circuit (FPC) board for connecting multiple modules and a touch sensitive display module using the same. The single flexible printed circuit (FPC) board for connecting multiple modules includes a thin film which 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

technical field [0001] The present invention relates to a flexible printed circuit board (FPC board), and in particular to a single-chip flexible printed circuit board connected to multiple modules and a touch display module using the same. Background technique [0002] Touch panels are now widely used in various electronic products, especially many display panels are equipped with touch panels, allowing users to directly click and press the screen with their fingers or stylus. For example, the driving principle of the resistive touch panel is to use the voltage drop to sense the coordinate point of the pressed position; while the capacitive touch panel forms a uniform electric field on the panel and senses the current of the pressed position to calculate its coordinates. Afterwards, data processing can be performed according to the coordinate points through the flexible circuit board and the control circuit, and an image can be generated on the display panel to provide use...
