DETAILED DESCRIPTION

[0031] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the scheme of the embodiments of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the embodiments of the utility model, but the embodiments of the utility model can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the utility model, rather than all of the embodiments.

[0033] The stylus configured for the electronic device can be an electromagnetic pen or a capacitive pen. For the electromagnetic pen, the electromagnetic pen has higher precision and sensitivity, and is particularly suitable for scenes with high precision requirements such as drawing and design. For the capacitive pen, the capacitive pen is more versatile, but the precision is slightly lower, and it is suitable for portable designs such as general-purpose tablets and mobile phones. It can be seen that the capacitive pen and the electromagnetic pen have their own suitable usage scenarios, and the existing electronic devices on the market are designed based on the electromagnetic pen or are designed separately based on the capacitive pen, so they are not compatible with the electromagnetic pen and the capacitive pen, and therefore cannot meet the needs of different usage scenarios.

[0034] To solve the above problems, refer to Figure 1 As shown, this embodiment provides an electronic device, including a housing 1, an electromagnetic induction structure 2, a capacitive induction structure 3, a touch glass 4 and a display glass 5.

[0035] The display glass 5 is disposed on one side of the housing 1 , and the touch glass 4 is embedded in the display glass 5 or located on a side of the display glass 5 away from the housing 1 .

[0036] The electromagnetic induction structure 2 is arranged between the display glass 5 and the shell 1 and is used for electromagnetic induction cooperation with the external electromagnetic pen 6; the capacitive induction structure 3 is arranged on the side of the touch glass 4 close to the shell 1 and is used for capacitive induction cooperation with the external capacitive pen 7.

[0037] When implementing it, refer to Figure 1 In the up-down direction shown, it is assumed that the display glass 5 is located above the housing 1 . In this case, the touch glass 4 can be embedded in the display glass 5 or can also be arranged on the upper surface of the display glass 5 .

[0038] The electromagnetic induction structure 2 is arranged between the display glass 5 and the housing 1, and the electromagnetic induction structure 2 cooperates with the electromagnetic pen 6 to identify the position and movement trajectory of the electromagnetic pen 6, thereby realizing the writing function of the electromagnetic pen 6 on the electronic device. The capacitive sensing structure 3 is arranged below the touch glass 4 and cooperates with the capacitive pen 7 to identify the position and movement trajectory of the capacitive pen 7, thereby realizing the writing function of the capacitive pen 7 on the electronic device.

[0039] Specifically, the writing principle of the electromagnetic pen 6 is briefly described as follows: the electromagnetic induction structure 2 first transmits an electromagnetic signal to the electromagnetic pen 6, and the electromagnetic pen 6 generates a feedback signal after receiving the electromagnetic signal. The electromagnetic induction structure 2 receives the feedback signal and calculates the position and motion trajectory of the electromagnetic pen 6 according to the feedback signal, and then realizes the writing function of the electromagnetic pen 6. The writing principle of the capacitive pen 7 is briefly described as follows: when writing, the capacitive pen 7 contacts the touch glass 4 and generates a capacitance change between the touch glass 4, and the capacitance change is finally converted into a voltage change. The capacitive sensing structure 3 senses the voltage change of the touch glass 4 at this position and can locate the position, and calculate the position coordinates of the position, thereby realizing the recognition of the position and motion trajectory of the capacitive pen 7, and then realizing the writing function of the capacitive pen 7. The specific principles of the writing functions of the electromagnetic pen 6 and the capacitive pen 7 can refer to the description of the relevant technology, and this embodiment will not be described in detail.

[0040] Exemplarily, the touch glass 4 may be a touch layer made of an ITO (Indium Tin Oxides) film. Through different processes, the touch glass 4 may be disposed on the display glass 5 or may be embedded in the display glass 5 .

[0041] Exemplarily, the housing 1 may be a metal housing 1, such as an iron housing 1. Alternatively, the housing 1 may be an alloy housing 1 or the like.

[0042] The electronic device provided in this embodiment includes a shell 1, an electromagnetic induction structure 2, a capacitive induction structure 3, a touch glass 4 and a display glass 5. The display glass 5 is arranged on one side of the shell 1, and the touch glass 4 is embedded in the display glass 5 or arranged on the side of the display glass 5 away from the shell 1. An electromagnetic induction structure 2 for electromagnetic induction cooperation with an external electromagnetic pen 6 is arranged between the display glass 5 and the shell 1, and a capacitive induction structure 3 for capacitive induction cooperation with an external capacitive pen 7 is arranged on the side of the touch glass 4 close to the shell 1, so that the electromagnetic induction structure 2 can be used to perform electromagnetic induction cooperation with the electromagnetic pen 6, and the capacitive induction structure 3 can be used to perform capacitive induction cooperation with the capacitive pen 7, so as to realize the writing operation of the electromagnetic pen 6 and the writing operation of the electromagnetic pen 6, that is, the electronic device can be adapted to the electromagnetic pen 6 and the capacitive pen 7 at the same time, thereby improving its compatibility to meet the diverse choices of users.

[0043] Reference Figure 1 As shown, in some embodiments, the capacitive sensing structure 3 includes a capacitive sensing chip 31 and a capacitive sensing plate assembly 32 .

[0044] The capacitive sensing board assembly 32 is disposed on a side of the touch glass 4 close to the housing 1 , and the capacitive sensing chip 31 is disposed on the capacitive sensing board assembly 32 and cooperates with the capacitive stylus 7 for capacitive sensing.

[0045] In specific implementation, the capacitive sensing circuit substrate can be arranged below the touch glass 4 and the capacitive sensing chip 31 can be arranged on the capacitive sensing board assembly 32. When the capacitive pen 7 contacts the touch glass 4, a capacitance change occurs between the capacitive pen 7 and the touch glass 4 and the capacitance change is finally converted into a voltage change. After sensing the voltage change of the touch glass 4 at the position, the capacitive sensing chip 31 can locate the position and calculate the position coordinates of the position, thereby realizing the recognition of the position and motion trajectory of the capacitive pen 7, and then realizing the writing function of the capacitive pen 7.

[0046] Reference Figure 1 As shown, in some embodiments, the capacitive sensing board assembly 32 includes a first circuit substrate 321 and a capacitive touch circuit board 322 connected to the first circuit substrate 321 .

[0047] The first circuit substrate 321 is disposed on a side of the touch glass 4 close to the housing 1 , and the capacitive sensing chip 31 is disposed on the capacitive touch circuit board 322 .

[0048] That is to say, the capacitive sensing chip 31 can be electrically connected to the first circuit substrate 321 through the capacitive touch circuit board 322. The first circuit substrate 321 can be specifically set on the lower surface of the touch glass 4. Therefore, when the capacitive pen 7 contacts the touch glass 4 and generates a capacitance change with the touch glass 4 and finally converts it into a voltage change, the voltage change can be transmitted to the capacitive sensing chip 31 through the first circuit substrate 321 and the capacitive touch circuit board 322, so that the capacitive sensing chip 31 receives the voltage change and calculates it to locate the position of the capacitive pen 7, thereby realizing the recognition of the position and movement trajectory of the capacitive pen 7, and then realizing the writing function of the capacitive pen 7.

[0049] Reference Figure 1 As shown, in some embodiments, the electromagnetic induction structure 2 includes an electromagnetic induction member 21 and an electromagnetic induction component 22 .

[0050] The electromagnetic induction element 21 is disposed between the display glass 5 and the housing 1 and cooperates with the electromagnetic pen 6 by electromagnetic induction. The electromagnetic induction component 22 is disposed on a side of the electromagnetic induction element 21 close to the housing 1 and is electrically connected to the electromagnetic induction element 21 .

[0051] In a specific implementation, the electromagnetic induction element 21 is arranged between the display glass 5 and the housing 1, and the electromagnetic induction component 22 is arranged below the electromagnetic induction element 21. When the electromagnetic pen 6 needs to be used for writing, since the electromagnetic pen 6 is a passive component, the electromagnetic induction element 21 first transmits an electromagnetic signal to the electromagnetic pen 6, and the electromagnetic pen 6 generates a feedback signal after receiving the electromagnetic signal. The electromagnetic induction element 21 receives the feedback signal and transmits the feedback signal to the electromagnetic induction component 22, and the electromagnetic induction component 22 calculates and obtains the position and motion trajectory of the electromagnetic pen 6 according to the feedback signal, and then realizes the writing function of the electromagnetic pen 6.

[0052] Exemplarily, the electromagnetic induction element 21 may be an electromagnetic film, or an electromagnetic induction plate, etc.

[0053] Reference Figure 1 As shown, in some embodiments, the electromagnetic induction component 22 includes an electromagnetic induction chip 221 and an electromagnetic induction plate member 222 .

[0054] The electromagnetic induction plate member 222 is disposed on a side of the electromagnetic induction component 21 close to the housing 1 and is electrically connected to the electromagnetic induction component 21 . The electromagnetic induction chip 221 is disposed on the electromagnetic induction plate member 222 .

[0055] In specific implementation, when the electromagnetic pen 6 is needed to write, the electromagnetic induction component 21 first transmits an electromagnetic signal to the electromagnetic pen 6. After the electromagnetic pen 6 receives the electromagnetic signal, it generates a feedback signal. The electromagnetic induction component 21 receives the feedback signal and transmits the feedback signal to the electromagnetic induction chip 221 through the electromagnetic induction plate component 222. The electromagnetic induction chip 221 calculates the position and motion trajectory of the electromagnetic pen 6 according to the feedback signal, and then realizes the writing function of the electromagnetic pen 6.

[0056] Reference Figure 1 As shown, in some embodiments, the electromagnetic induction plate component 222 includes a second circuit substrate 223 and an electromagnetic touch circuit board 224 connected to the second circuit substrate 223 .

[0057] The second circuit substrate 223 is disposed on a side of the electromagnetic induction component 21 close to the housing 1 and is electrically connected to the electromagnetic induction component 21 . The electromagnetic induction chip 221 is disposed on the electromagnetic touch control circuit board 224 .

[0058] That is to say, the electromagnetic induction chip 221 can be electrically connected to the second circuit substrate through the electromagnetic touch circuit board 224. The second circuit substrate can be specifically arranged below the electromagnetic induction component 21. Therefore, when the electromagnetic pen 6 is needed, the electromagnetic induction component 21 transmits an electromagnetic signal to the electromagnetic pen 6. The electromagnetic pen 6 receives the electromagnetic signal and generates a feedback signal. The electromagnetic induction component 21 receives the feedback signal and feeds back to the capacitive sensing chip 31 through the second circuit substrate and the electromagnetic touch circuit board 224. The capacitive sensing chip 31 receives the voltage change and calculates it to locate the position of the capacitive pen 7, thereby realizing the recognition of the position and motion trajectory of the capacitive pen 7, and then realizing the writing function of the capacitive pen 7.

[0059] Reference Figure 1 As shown, in some embodiments, the electronic device further includes a backlight layer 8, which is disposed between the display glass 5 and the electromagnetic induction structure 2 to achieve a uniform light effect. Alternatively, when the display glass 5 is an OLED (organic Light-Emitting Diode) glass, the backlight layer 8 may not be disposed.

[0060] In some embodiments, the electronic device includes a learning tablet. Alternatively, in other implementations, the electronic device may also be a mobile terminal with a touch function, such as a touch notebook.

[0061] Reference Figure 1 to Figure 2 As shown, this embodiment also provides an electronic device assembly, including a stylus pen 9 and the above-mentioned electronic device.

[0062] The specific structure and implementation principle of the electronic device in this embodiment are the same as the structure of the electronic device provided in the above embodiment, and can bring the same or similar technical effects, which will not be described one by one here, and the details can be referred to the description of the above embodiment.
