When the folding screen of the first folding portion 10 and the folding screen of the second folding portion 20 are disposed opposite to each other, i.e., after being folded, the folding screen of the folding mechanism does not face the user, and the folding screen is turned off at this time. When the folding screen of the first folding portion 10 and the folding screen of the second folding portion 20 are oppositely arranged in the folding state, if the folding screen of the first folding portion 10 faces a user, the folding screen of the first folding portion 10 displays an interface, and the folding screen of the second folding portion 20 is turned off; if the folded screen of the second folding portion 20 faces the user, the folded screen of the second folding portion 20 displays an interface, and the folded screen of the first folding portion 10 is turned off.

Similarly, the induction coil 40 is not limited to be disposed at the second folded portion 20, and may be disposed at the first folded portion 10. That is to say, the transmitting coil 30 and the induction coil 40 are respectively disposed at two different folding portions, and the transmitting coil 30 and the induction coil 40 can rotate along with the two folding portions, so that the transmitting coil 30 and the induction coil 40 can move relatively, and those skilled in the art can flexibly adjust the position according to actual needs without limitation.

By means of electromagnetic induction, the transmitting coil 30 transmits an electromagnetic wave signal, the transmitting coil 30 and the induction coil 40 perform electromagnetic induction, the induction coil 40 generates an induction current, and the induction coil 40 is used for receiving the electromagnetic wave signal transmitted by the transmitting coil 30. When the folding mechanism is in a folding process, when the transmitting coil 30 and the induction coil 40 are close to each other, the induced current generated by the induction coil 40 is larger, that is, the intensity of the received electromagnetic wave signal is larger, whereas when the folding mechanism is in an unfolding process, when the transmitting coil 30 and the induction coil 40 are far away from each other, the intensity of the electromagnetic wave signal received by the induction coil 40 is smaller. The transmitting coil 30 and the induction coil 40 are respectively fixed on the first folding part 10 and the second folding part 20, and the relative position change between the first folding part 10 and the second folding part 20 can be determined according to the relative position change between the transmitting coil 30 and the induction coil 40, so that the state determination of the folding mechanism is realized, for example, the folding mechanism is in the folding process or the unfolding process.

Alternatively, the present application may determine the distance between the transmitting coil 30 and the induction coil 40 according to the strength of the electromagnetic wave signal received by the induction coil 40, determine the relative position relationship between the transmitting coil 30 and the induction coil 40 according to the distance change between the two, and further determine the relative position relationship between the first folding portion 10 and the second folding portion 20.

Alternatively, when the strength of the electromagnetic wave signal received by the induction coil 40 changes and the trend of the change gradually increases, it may be determined that the transmitting coil 30 and the induction coil 40 are close to each other, that is, the first folding portion 10 and the second folding portion 20 are close to each other, and the state of the folding mechanism is switched from the unfolded state to the folded state.

When the intensity of the electromagnetic wave signal received by the induction coil 40 changes and the trend of the change gradually decreases, it can be determined that the transmitting coil 30 and the induction coil 40 are away from each other, that is, the first folding portion 10 and the second folding portion 20 are away from each other, and the state of the folding mechanism is switched from the folding state to the unfolding state.

Optionally, the present application may also determine the distance between the transmitting coil 30 and the induction coil 40 according to the strength of the electromagnetic wave signal received by the induction coil 40 and according to the strength of the electromagnetic wave signal received by the induction coil 40. Meanwhile, according to the distance between the induction coil 40 and the projection of the induction coil 40 formed on the first folding portion 10 and the distance between the transmission coil 30 and the projection of the transmission coil 30 formed on the second folding portion 20, the included angle formed between the first folding portion 10 and the second folding portion 20 is calculated, and the relative position relationship between the first folding portion 10 and the second folding portion 20 is determined.

Alternatively, the smaller the angle formed between the first folding portion 10 and the second folding portion 20, the closer the first folding portion 10 and the second folding portion 20 are to each other, and the state of the folding mechanism is switched from the unfolded state to the folded state. The larger the angle formed between the first folding portion 10 and the second folding portion 20 is, the farther the first folding portion 10 and the second folding portion 20 are from each other, and the state of the folding mechanism is switched from the folded state to the unfolded state.

Based on this, compared with the method of using two acceleration sensors (a + G) to detect and calculate the screen state, the software algorithm is complex in calculation, which easily increases the processing progress of the processor 55, or senses the screen state through the light sensing device (ALPS), the probability of false triggering is high, and optical devices such as the light beam are difficult to debug, or senses the screen state through the combination of the HALL sensor (HALL) device and the magnetic device, so that the problem of the placement position of the magnet exists, and the magnet is generally required to prevent the screen from being directly below and having great damage to the screen. All three detection devices need to be fixed on the main board, so that the installation position is limited and the position is not flexible enough.

The first folding part 10 and the second folding part 20 are arranged, and the first folding part 10 is rotatably connected with the second folding part 20; the state of the folding mechanism is determined by the aid of the transmitting coil 30 and the induction coil 40 by arranging the transmitting coil 30 and the induction coil 40 and respectively arranging the transmitting coil 30 and the induction coil 40 on the first folding part 10 and the second folding part 20; optionally, the state of the folding mechanism comprises a folded state and an unfolded state; the transmitter coil 30 and the induction coil 40 are close to each other when the folding mechanism is in the folding process, and the transmitter coil 30 and the induction coil 40 are far from each other when the folding mechanism is in the unfolding process. Electromagnetic energy emitted by the emitting coil 30 does not generate loss due to factors such as the setting position and the medium, transmission efficiency is high, and the state detection precision and convenience of the folding mechanism are improved. Alternatively, the first folding portion 10 and the second folding portion 20 may be mounted at any position without being affected by the spatial position. In addition, the transmitting coil 30 and the induction coil 40 have simple structures, are easy to implement, and occupy a small space on the folding screen assembly.
