All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 and fig. 2, the present embodiment provides a terminal device, where the terminal device at least includes: first lid 1, second lid 2, MIPI camera module 3, integrated DSP function's CPU 4, connecting wire 5.

The MIPI camera module 3 is arranged on the first cover body 1 and used for collecting original video or image signals and outputting the signals according to the MIPI format.

The CPU 4 integrating the DSP function is installed in the second lid 2, and serves as a final execution unit for information processing and program operation of the terminal device.

MIPI camera module 3 is connected to the one end electricity of connecting wire 5, and CPU 4 is connected to the other end electricity for realize the signal transmission between MIPI camera module 3 and CPU 4.

In the operation process of the terminal equipment, the MIPI camera module 3 outputs an original video or image signal in an MIPI format and transmits the original video or image signal to the CPU 4 through the connecting wire 5, and the CPU 4 carries out image debugging processing and then outputs the image signal.

Specifically, the MIPI camera module 3 includes a PCB or a flexible board, a camera body, a connector or a pad. The camera body and the connector or the bonding pad are attached to the PCB or the soft board, and the connector or the bonding pad is used for being electrically connected with the camera body and the connecting wire 5 to realize signal transmission between the camera body and the connecting wire. Among them, the connector may be specifically a BTB (board to board) connector and a ZIF (zero insertion force) connector.

Compared with a USB camera module, the MIPI camera module 3 omits a DSP chip, and meanwhile, the CPU 4 integrating the DSP function is used for realizing the image debugging processing function. Therefore, by using the existing resource to realize the signal processing function, the production cost of the camera module can be effectively reduced on the basis of ensuring normal work, and the restriction of a DSP chip on the production and the manufacture of the camera module is eliminated; in addition, because the MIPI camera module 3 supports higher pixels, the image quality of the terminal equipment can be improved, and the high-quality use requirement of a terminal user is met.

The connecting wire 5 can adopt a single wiring mode or a combined wiring mode:

in the single wiring mode: as shown in fig. 3, the CPU 4 is electrically connected to the MIPI camera module 3 through an FPC, an FFC, or an electronic wire;

in the combined wiring mode:

as shown in fig. 4, the CPU 4 is electrically connected to the MIPI camera module 3 sequentially through the FPC, the electronic wire, and the FPC;

or, as shown in fig. 5, the CPU 4 is electrically connected to the MIPI camera module 3 sequentially through the FPC, the FFC, the electronic wire, the FFC, and the FPC;

or, as shown in fig. 6, the CPU 4 is electrically connected to the MIPI camera module 3 sequentially through the FPC, the electronic wire, and the FFC;

or, as shown in fig. 8, the CPU 4 is electrically connected to the MIPI camera module 3 sequentially through the FPC, the FFC, the electronic wire, and the FFC;

or, as shown in fig. 9, the CPU 4 is electrically connected to the MIPI camera module 3 sequentially through the FFC, the electronic wire, the FFC, and the FPC;

when the combined wiring mode is adopted, two adjacent sections of the connecting wires 5 are electrically connected in a welding mode.

In order to control the impedance of the MIPI signal, as shown in fig. 10, the FFC and the FPC are wired by using differential signals, and an aluminum foil is attached to the outer layer of the FFC; the conventional material of the electronic wire is PE (polyethylene), PP (polypropylene), FEP (perfluoroethylene propylene copolymer), coaxial line and the like, and other electronic wires except the coaxial line need to adopt a pair-twisting wiring mode to ensure that MIPI signal wires are twisted in pairs, as shown in figure 11, MDP and MDN, MCP and MCN are twisted in pairs.

It should be noted that the FFC is a novel data cable formed by laminating a PET insulating material and an extremely thin tinned flat copper wire through a high-tech automatic equipment production line, and has the advantages of softness, random bending and folding, thin thickness, small volume, simple connection, convenience in disassembly, easiness in solving electromagnetic shielding and the like.

The FPC is a flexible printed circuit board which is made of polyimide or polyester film as a base material and has high reliability and excellent performance, and has the characteristics of high wiring density, light weight, thin thickness and good bending property.

The bending resistance of the electronic wire is better than that of FFC and FPC.

In practical application, a suitable wiring mode of the connecting wire 5 can be selected according to the whole structure of the terminal device (for example, the type of the connector of the MIPI camera module 3) and the customized requirements of customers.

Based on the wiring manner, the connecting wire 5 of the embodiment of the invention can be matched with the current terminal equipment, and long-distance output is realized by combining and utilizing the advantages of the connecting wires 5 of different types.

In an alternative embodiment, the opening and closing mechanism for opening and closing the first cover 1 and the second cover 2 may include a rotating shaft 6, and the two covers may be opened or closed through the rotating shaft 6. It is understood that the opening and closing mechanism may further include other limiting members to limit the opening angle of the two covers. Of course, the opening and closing structure may also adopt any other structure, and the embodiment of the present invention is not limited thereto. When the rotating shaft 6 is used, the connecting wire 5 passes through the rotating shaft 6 for assembly. When a single FFC or FPC wire is adopted, the position of the over-rotation shaft 6 of the FFC or FPC can be bundled or laminated. When other combined wiring modes including the electronic wire are adopted, the electronic wire can pass through the rotating shaft 6 so as to utilize the excellent bending resistance of the electronic wire.

To sum up, the terminal device provided by the embodiment of the invention adopts the MIPI camera module 3, and simultaneously utilizes the superior connecting wire 5 structure to perform long-distance output, thereby realizing low cost and high performance.

It should be noted that the terminal device may be implemented in various forms. For example, the terminal device described in the present invention may include various electronic devices having a camera function, such as a flip phone, a notebook computer, a palm top computer, a Personal Digital Assistant (PDA), a Portable Media Player (PMP), and the like.

The first cover body 1 and the second cover body 2 are connected through a rotating shaft 6.

Wherein, display screen 7 and MIPI camera module 3 are installed in first lid 1, and MIPI camera module 3 arranges in the upper frame region of display screen 7 to make things convenient for the user to use. And the case is arranged in the second cover body 2.

In this embodiment, the MIPI camera module 3 outputs an original video or image signal in the MIPI format and transmits the original video or image signal to the CPU 4 through the connecting line 5, and the original video or image signal is output to the display screen 7 for display after being subjected to image debugging processing by the CPU 4. The connecting wire 5 realizes the signal transmission of a longer distance between the MIPI camera module 3 positioned at the frame position and the CPU 4 positioned at the lower cover. Optionally, the length of the connecting line 5 is 400mm to 630 mm.

Because the notebook computer adopts the MIPI camera module 3, the MIPI camera module 3 omits a DSP chip, and simultaneously, the CPU 4 integrating the DSP function is utilized to realize the image debugging processing function. Therefore, the mode of realizing the signal processing function by utilizing the existing resources effectively reduces the production cost of the camera module, gets rid of the restriction of a DSP chip and can also improve the image quality of the notebook computer.
