Background technique

When the mobile phone is working, some data needs to be transmitted over a long distance inside the mobile phone. For example, the data from the USB port needs to be transmitted to the motherboard of the mobile phone, and the battery in the mobile phone needs to be crossed in the middle; for example, the information of the display chip is transmitted to The motherboard in the mobile phone needs to pass through the middle frame of the mobile phone, etc. At this time, the intermediate transmission channel needs to be bent.

At present, copper wires are often set in FPC (flexible printed circuit board), and the copper wires are used as intermediate transmission channels for signal transmission. Since the copper wire is easy to bend, the bending treatment of the intermediate transmission channel can be realized. However, to ensure that the copper wire does not break during the folding process of the mobile phone, the copper wire needs to be made thinner and can only be made in a single layer. In this way, when there are many signal channels, the FPC needs to be made wider, which is likely to conflict with the smaller range of the whole machine architecture.

First, referring to FIGS. 1 to 6, the mobile terminal provided by the present application includes a first signal area 2 and a second signal area 3 capable of signal transmission, and the signal of the first signal area 2 can be transmitted to the second signal area 3. The signal of the second signal area 3 may also be transmitted to the first signal area 2. Specifically, the first signal area 2 includes two parts, namely: the first signal aggregation module 201 and the first signal conversion module 202; correspondingly, the second signal area 3 also includes two parts, respectively: Two signal aggregation module 301 and second signal conversion module 302. In addition, the mobile terminal 1 also includes a flexible signal transmission medium 4 that signals the first signal area 2 and the second signal area 3. When the first signal area 2 is specifically set, the first signal aggregation module 201 and the first signal conversion module 202 are connected, and when the second signal area 3 is specifically set, the second signal aggregation module 301 and the second signal conversion module are connected. Group 302 is connected; when the first signal area 2 is connected, the first signal conversion module 202 and the second signal conversion module 302 are connected through the flexible signal transmission medium 4.

In a possible implementation of the present application, the first signal area 2 is a signal sending area, the second signal area 3 is a signal receiving area, and the multiple signal sources 5 of the first signal area 2 (such as high-speed MIPI signals, medium and low speed CLK signal, control signal, etc.) are aggregated into a first aggregate signal through the first signal aggregation module 201, and the first signal conversion module 202 converts the first aggregate signal so that it can be transmitted through the flexible signal transmission medium 4.

By the same principle, when the second signal area 3 is a signal sending area and the first signal area 2 is a signal receiving area, the signal transmission process of the two signal areas is similar to the above process. It can be seen from the above description that when the signals of the two signal areas of the mobile terminal 1 are being transmitted, the signal sources 5 in one of the signal areas are aggregated and converted and then transmitted to the other signal through the flexible signal transmission medium 4. This can effectively reduce the number of signal transmission channels, thereby reducing the occupied space of the flexible signal transmission medium 4; and the first signal conversion module 202 and the second signal conversion module 302 group are connected through the flexible signal transmission medium 4.

Similarly, the second signal can also be converted by the second signal conversion module 302. The signals aggregated by the aggregation module 301 are converted into high-frequency electromagnetic waves, so that the high-frequency electromagnetic waves are used as transmission carriers for signal transmission. Among them, the high-frequency electromagnetic waves can be millimeter waves, terahertz or light waves.

When the high-frequency waves are light waves, the flexible signal transmission The medium 4 may be an optical fiber 402. In a specific embodiment of the present application, the high-frequency electromagnetic wave used as the transmission carrier is millimeter wave. When the first signal area 2 is specifically set, the first signal aggregation module 201 includes the first millimeter wave aggregation chip 2011 and The first millimeter wave transmission chip 2012 and the first signal conversion module 202 are the first millimeter waveguide converter 2021. Correspondingly, when the second signal area 3 is specifically set, the second signal aggregation module 301 includes a second millimeter wave aggregation chip 3011 and a second millimeter wave transmission chip 3012 that are signal-connected, and the second signal conversion module 302 is a second The millimeter waveguide converter 3021, wherein the first millimeter waveguide converter 2021 and the second millimeter waveguide converter 3021 are connected by a dielectric waveguide sheet 401. The dielectric waveguide sheet 401 can be made of materials with uniform texture and good bending resistance, such as PI (polyimide), PE (polyethylene), PC (polycarbonate), PET (Polyethylene terephthalate) or PP (polypropylene).

Taking the first signal area 2 as the signal sending area and the second signal area 3 as the signal receiving area as an example, the signal transmission process between the two signal areas is specifically illustrated. First, the different signal sources 5 in the first signal area 2 are transmitted to the first millimeter wave aggregation chip 2011, and the different signal sources 5 are collected together through the first millimeter wave aggregation chip 2011 and then transmitted to the first millimeter wave transmission Chip 2012; then, the first millimeter wave transmission chip 2012 modulates and amplifies the aggregated signals to form a first aggregate signal; after that, the first millimeter waveguide converter 2021 converts the first aggregate signal into a first transmission signal, In order to realize the conversion of signal from microstrip transmission to waveguide transmission, the first millimeter waveguide converter 2021 is provided between the first millimeter wave transmission chip 2012 and the dielectric waveguide sheet 401, and can be used as an impedance converter to make the signal The transmitted energy is maximized, thereby improving the signal transmission distance and transmission quality; finally, the first transmission signal is transmitted to the second signal area 3 through the dielectric waveguide sheet 401, and then transmitted to the second millimeter through the second millimeter waveguide converter 3021 The second transmission signal is obtained after amplification and demodulation in the wave transmission chip 3012, and the second millimeter wave aggregation chip 3011 disperses the second transmission signal to the corresponding signal processing terminal in the second signal area for processing. In this embodiment, when the second signal area 3 is a signal sending area and the first signal area 2 is a signal receiving area, the signal transmission process is similar to the above process, and will not be repeated here.

The above methods for signal transmission using millimeter waves and terahertz as carrier waves are also applicable to the case of using light waves as carrier waves for signal transmission. When only light waves are used as the carrier wave for signal transmission, the first signal aggregation module 201 and the first signal conversion module 202, the second signal aggregation module 301 and the second signal conversion module 302, and the flexible signal transmission medium 4 are required. Adjust the settings accordingly. As shown in Figures 2, 4 and 6, in a possible embodiment of the present application, the first signal aggregation module 201 is a first optical communication module 2015, and the first signal conversion module 202 is a first photoelectric conversion module.

After the two photoelectric converters 3023 are converted into electrical signals, they are transmitted to the second optical communication module 3015 for amplification and demodulation to obtain the second transmission signal, which is dispersed to the corresponding signal processing terminal in the second signal area for processing. In this embodiment, when the second signal area 3 is a signal sending area and the first signal area 2 is a signal receiving area, the signal transmission process is similar to the above process, and will not be repeated here.

In this embodiment, a plurality of signals in a signal area are aggregated and modulated and converted into light wave transmission to maximize the energy of signal transmission, thereby effectively improving the signal transmission distance and transmission quality, and, The optical fiber 402 has better bending resistance.
