Generally, a liquid crystal touch device (hereinafter, referred to as a liquid crystal touch device) with a touch function includes a system, a liquid crystal display panel, a touch panel and a light source.

In an embodiment of the invention, an uncompounded signal transmission device is provided, as shown in fig. 3, including a first flexible printed circuit board 110 and a second flexible printed circuit board 120. The first flexible printed circuit board 110 can be electrically connected to the display module 100 and a system (not shown), and the first flexible printed circuit board 110 is provided with a plurality of port portions 202. The port portion 202 is electrically connected to the circuit of the first flexible printed circuit board 110, so that other components can be electrically connected to the first flexible printed circuit board 102 through the port portion 202. The second flexible printed circuit board 120 is electrically connected to the display module 100 and is provided with a port connector 201. The port connector 201 is electrically connected to the circuit of the second flexible printed circuit board 120, so that other components can be electrically connected to the first flexible printed circuit board 110 through the port portion 202. The port connector 201 is coupled to the port portion 202, and can be fixed or detachable according to the requirement. The port connector 201 can be inserted, embedded, or connected to the port portion 202 by any known method such as spring plate, tenon, etc., and is in an electrical connection state during connection, so that the second flexible printed circuit board 120 with the port connector 201 is electrically connected to the first flexible printed circuit board 110 with the port portion 202.
In the above embodiments, the port portion 202 may be single or plural, and may be disposed on any side of the first flexible printed circuit board 110. For example, the port 202 may be disposed on the upper surface, the lower surface, the peripheral edge or other locations of the first flexible printed circuit board 110. However, the above arrangement at least ensures that the port 202 can be electrically connected to the circuit of the first flexible printed circuit board 110, so that the signal can be input or output to the first flexible printed circuit board 110 through the port 202.
On the other hand, the port connector 201 may be single or plural, and may be disposed on any side of the second flexible printed circuit board 120. For example, the port 202 may be disposed on the upper surface, the lower surface, the peripheral edge or other locations of the second flexible printed circuit board 120. However, the above arrangement at least needs to ensure that the port connector 201 can be electrically connected to the circuit of the second flexible printed circuit board 120, so that the signal can be input or output to the first flexible printed circuit board 110 through the port connector 201.
The first flexible printed circuit board 110 can be electrically connected to the second flexible printed circuit board 120 by connecting the port connector 201 and the port portion 202. The first flexible printed circuit board 110 and the second flexible printed circuit board 120 can be configured differently according to the positions of the port connector 201 and the port portion 202. For example, the first flexible printed circuit board 110 and the second flexible printed circuit board 120 may be located on the same plane and adjacent to each other; or the first FPC 110 and the second FPC 120 may be located on different planes; or the first flexible printed circuit board 110 and the second flexible printed circuit board 120 may partially overlap. However, the actual configuration is not limited thereto, but at least the effect of electrically connecting the first flexible printed circuit board 110 and the second flexible printed circuit board 120 is achieved.
In the embodiment of the invention, the first flexible printed circuit board 110 may be directly connected to the display module 100, or may not be directly connected to the display module 100. In the case of direct connection with the display module 100, the first flexible printed circuit board 110 can directly receive signals from the display module 100; without being directly connected to the display module 100, the first flexible printed circuit board 110 can be electrically connected to the display module 10 through the second flexible printed circuit board 120, the port connector 201 and the port portion 202 to receive signals from the display module 100. The first flexible printed circuit board 110 may further include a connecting portion 500 for electrically connecting to a system. And transmitted to the system through the connection 500.
The second flexible printed circuit board 120 may be electrically connected to a light source of the display module 100 or a touch panel (not shown), and transmits a light source signal provided by the light source and/or transmits a touch signal provided by the touch panel. The second flexible printed circuit board 120 may be disposed on a different side of the display module 100 from the first flexible printed circuit board 110, or may be disposed on the same side of the display module 100 as the first flexible printed circuit board 110.
Optionally, the first flexible printed circuit board 110 and the second flexible printed circuit board 120 are further fixed in relative positions by alignment marks. Optionally, in addition to the port connector 201 and the port portion 202, after the first flexible printed circuit board 110 and the second flexible printed circuit board 120 are aligned by the alignment mark, the connection therebetween can be strengthened by a method known in the art to fix the relative position therebetween.
In addition, the signal transmission device of the present invention may further include a third flexible printed circuit board 130. The third flexible printed circuit board 130 may have the same function as the second flexible printed circuit board 120. That is, the third flexible printed circuit board 130 may be electrically connected to a light source of the display module 100 or a touch panel (not shown), and transmits a light source signal provided by the light source and/or transmits a touch signal provided by the touch panel. Similarly, the third flexible printed circuit board 130 may be disposed on a different side of the display module 100 from the first flexible printed circuit board 110, or may be disposed on the same side of the display module 100 as the first flexible printed circuit board 110. The third flexible printed circuit board 130 may also be disposed on a different side of the display module 100 from the second flexible printed circuit board 120, or may be disposed on the same side of the display module 100 as the second flexible printed circuit board 120.
Alternatively, the third flexible printed circuit board 130 and the second flexible printed circuit board 120 may transmit different signals, respectively. For example, the third flexible printed circuit board 130 may be configured to be electrically connected to a light source of the display module 100 for transmitting a light source signal, and the second flexible printed circuit board 120 may be configured to be electrically connected to a touch panel of the display module 100 for transmitting a touch signal.
In another embodiment of the present invention, the signal transmission device described above may be disposed in a liquid crystal display device for transmitting signals, thereby providing an improved liquid crystal display device.
In addition to the above embodiments, several components may be optimized according to actual conditions and requirements, so as to further enhance the advantages of the present invention.
In one embodiment, a composite signal transmission apparatus is provided. The configuration relationship among the first flexible printed circuit board 110, the second flexible printed circuit board 120, and the third flexible printed circuit board 130 is optimized, and the first flexible printed circuit board 110, the second flexible printed circuit board 120, and the third flexible printed circuit board 130 are directly integrated into the composite signal transmission device 700 with a multi-layer structure without using the port connector 201 and the port portion 202. As shown in fig. 4, the fpc equivalent to the first fpc 110, the second fpc 120 and the third fpc 130 are respectively represented by a first fpc 111, a second fpc 121 and a third fpc 131 to separate them from the foregoing embodiments. The composite signal transmission device 700 is formed by overlapping the first flexible printed circuit board 111, the second flexible printed circuit board 121, and the third flexible printed circuit board 131, and disposing a multi-layer structure of the insulating layer 300 therebetween. The insulating layer 300 is provided with a plurality of through holes 310, and the conductive posts 320 are respectively disposed in the through holes 310, so that the separated first flexible printed circuit board 111, the second flexible printed circuit board 121, and the third flexible printed circuit board 131 can be electrically connected. Alternatively, the first flexible printed circuit board 110 can be replaced by a rigid printed circuit board. In addition, an insulating layer 300 may be further disposed under the first flexible printed circuit board 111.
The material of the insulating layer 300 may be, for example: polyimide, polyethylene terephthalate, polyethylene naphthalate, or other insulating materials commonly used in the art. The conductive pillars 320 may be conductive paste, anisotropic conductive film, or other conductive materials commonly used in the art.
For example, the second flexible printed circuit board 121 may be electrically connected to the light source of the display module 100, and the third flexible printed circuit board 131 may be electrically connected to the touch panel of the display module 100. The second flexible printed circuit board 121 and the third flexible printed circuit board 131 are electrically connected to the first flexible printed circuit board 111 through the conductive posts 320 disposed in the through holes 310, and further electrically connected to the system through the connection portion 500. However, the above is merely an example, and the configuration of the actual implementation can be adjusted according to the requirement. For example, the second flexible printed circuit board 121 and the third flexible printed circuit board 131 may be disposed on the same plane of the first flexible printed circuit board 111, and electrically connected to the first flexible printed circuit board 111 by the above-mentioned method.
In an exemplary embodiment of the present invention, a thin composite signal transmission device is provided. Similarly, the configuration relationship among the first flexible printed circuit board 110, the second flexible printed circuit board 120 and the third flexible printed circuit board 130 is optimized. A composite flexible printed circuit board similar to the multi-layer structure in the previous embodiment is integrated and applied on the first flexible printed circuit board 110, the second flexible printed circuit board 120 and the third flexible printed circuit board 130 to form a thin composite signal transmission device 800, which has the structure shown in fig. 5. In fig. 5, the thin composite signal transmission device 800 includes a first conductive pattern 112 equivalent to the circuit of the first flexible printed circuit board 110, a second conductive pattern 122 equivalent to the circuit of the second flexible printed circuit board 120, and a third conductive pattern 132 equivalent to the circuit of the third flexible printed circuit board 130. The first conductive pattern 112 may be disposed on any insulating substrate (not shown), and the insulating substrate is disposed with a conductive portion 500 electrically connected to the above structure.
The insulating layer 400 is disposed at the bottom of the thin composite signal transmission device 800 and between the first conductive pattern 112, the second conductive pattern 122, and the third conductive pattern 132, and the interlayer conductive structure 410 is disposed therein, such that the first conductive pattern 112, the second conductive pattern 122, and the third conductive pattern 132 are electrically connected through the interlayer conductive structure 410. The formation of the inter-layer via structure 410 includes forming at least one through hole in the insulating layer 400, and the wall of the through hole is plated through a chemical and electroplating process to form a conductive layer. The material of the plating layer can be metal or conductive plastic, or other materials with conductivity. The plating layer is electrically connected with the conductive patterns on the upper layer and the lower layer of the interlayer conduction structure, so that the conductive patterns are electrically connected with each other.
The difference between the thin composite signal transmission device 800 and the composite signal transmission device 700 of the previous embodiment is that the first conductive pattern 112, the second conductive pattern 122, and the third conductive pattern 132 are formed by stamping copper foils, and the thicknesses thereof are much smaller than those of the first flexible printed circuit board 111, the second flexible printed circuit board 121, and the third flexible printed circuit board 131. Therefore, the overall thickness of the thin composite signal transmission device 800 can be smaller than that of the composite signal transmission device 700.
In addition, although the insulating layer 400 of the thin composite signal transmission device 800 may be made of a single material, the insulating layer is divided into two parts, namely, an insulating layer that is originally in a solid state and a liquid insulating layer before curing, wherein the insulating layer 400 may be made of polyimide. The insulating layer 400 is disposed between the first conductive pattern 112, the second conductive pattern 122, and the third conductive pattern 132. An uncured liquid polyimide precursor solution, i.e., a material before the insulating layer 400 is cured, is applied between the insulating layer 400 and the three conductive patterns, and the organic solvent in the solution is removed through a heating step, so that the insulating layer 400 is cured. The insulating layer 400 configured in the above manner not only has an insulating effect, but also can be used as an adhesive material for assisting in adhering the first conductive pattern 112, the second conductive pattern 122 and the third conductive pattern 132, so that the structure of the thin composite signal transmission device 800 is more stable. In summary, the signal transmission device of the present embodiment can be manufactured by the process shown in fig. 6, wherein the steps S11 to S17 are briefly described above, and are only exemplary steps, which can be modified as required.
Similarly, the present invention also provides a liquid crystal display device by disposing the signal transmission device described above in a liquid crystal display device for transmitting signals, and the liquid crystal display device can have the benefits and effects of the embodiments of the signal transmission device. The arrangement mode of the circuit board is changed while the signal transmission effect of the circuit board is not influenced, and the larger process of the change factor of the welding step is avoided by reducing the ports connected with the system, so that the error probability can be reduced, and the product yield is improved.
The signal transmission device described above may be provided in other electronic devices, and is not limited to a display device, and when applied to a display device, the display device may be an LCD display device, an OLED display device, a QLED display device, a curved display device, or another display device.
The above-described contents are only detailed descriptions of preferred embodiments according to the present invention, and do not limit the scope of the right of the present invention. It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the principles and spirit of the invention. The scope of the invention is therefore intended to be indicated by the appended claims.
