[0065] Figure 1 is a schematic top view of an electronic device according to an embodiment of the present disclosure. Figure 1 , the electronic device 100 includes an integrated chip (IC) 110, a first touch module 120, and a second touch module 130. The integrated chip 110 is electrically connected to the first touch module 120 and the second touch module 130. In this embodiment, the integrated chip 110 is used to drive the first touch module 120 and the second touch module 130. In this embodiment, the electronic device 100 may be, for example, a vehicle display device, and is used to connect other electronic devices in the vehicle to, for example, provide functions such as audio and video, driving assistance, and / or peripheral device control in the vehicle.

[0066] In this embodiment, the electronic device 100 may include a first touch area 101, a second touch area 102, and a circuit configuration area 103. It is worth noting that the circuit configuration area described in this embodiment refers to a non-touch area adjacent to the touch area, and is used to set related driving circuits and / or chips. According to some embodiments, the circuit configuration area may be a non-display area adjacent to the display area. The circuit configuration area described in the present invention may be a different area on the same substrate as the touch area and / or display area, or a different area on different substrates, and the present invention is not limited thereto. For example, in Figure 1 In the embodiment, the circuit configuration area 103 is adjacent to the second touch control area 102 , and the integrated chip 110 is disposed in the circuit configuration area 103 .

[0067] In the present disclosure, the substrate may be a rigid substrate, a flexible substrate, or a rigid-flexible composite material. The substrate may be made of glass, quartz, organic material, inorganic material, polymer, wafer, ceramic, other applicable materials, or a combination thereof.

[0068] In this embodiment, the touch surfaces (and display surfaces) of the first touch area 101 and the second touch area 102 may be parallel to the plane formed by the direction D1 and the direction D2. The direction D1, the direction D2, and the direction D3 are perpendicular to each other. Alternatively, in one embodiment, the touch surfaces (and display surfaces) of the first touch area 101 and / or the second touch area 102 may be curved surfaces. In this embodiment, the electronic device 100 may provide touch and display functions through the first touch area 101, and the electronic device 100 may provide touch functions through the second touch area 102.

[0069] like Figure 1 As shown, in this embodiment, the first touch module 120 can be disposed in the first touch area 101, and includes a plurality of first touch electrodes 121_1 to 121_R, where R is a positive integer. The second touch module 130 can be disposed in the second touch area 102, and includes a plurality of second touch electrodes 131_1 to 131_N, where N is a positive integer. R and N can be equal or unequal, and there is no limitation. R can be greater than or less than N.

[0070] The display layer 122 includes a plurality of display electrodes 122_1 to 122_M, which may be disposed in the first touch area 101 but not disposed in the second touch area 102, where M is a positive integer. In the present disclosure, the display electrode may be a pixel electrode, a common electrode, an anode, a cathode, or a combination thereof. The plurality of display electrodes 122_1 to 122_M are separated from the second touch area 102.

[0071] The relative structural relationship between the first touch module 120 and the display electrode can be in-cell touch, on-cell touch, or out-cell touch.

[0072] like Figure 1As shown, in some embodiments, the first touch module 120 may be an embedded touch and an embedded touch module, which means that the touch electrodes and the display electrodes are arranged in the same panel (that is, a touch display panel) or in the same touch module. In other words, the first touch module 120 may include a display layer 122, the display layer 122 may include a plurality of display modules 122, and the plurality of display modules 122 include a plurality of display electrodes 122_1 to 122_M. For example, in an embedded touch display panel, the first touch module 120 may include a substrate, a plurality of first touch electrodes 121_1 to 121_R, and a plurality of display electrodes 122_1 to 122_M. The plurality of first touch electrodes 121_1 to 121_R and the plurality of display electrodes 122_1 to 122_M are arranged on the same substrate. Taking the display panel as a liquid crystal display panel as an example, the display electrodes 122_1 to 122_M may be pixel electrodes. The first touch electrode and the display electrode may overlap. For example, Figure 1 In the embodiment, the first touch electrodes 121_1 and the display electrodes 122_1 may overlap, and one first touch electrode 121_1 may overlap a plurality of display electrodes 122_1 to 122_M. When the electronic device 100 operates in the display mode, the first touch electrodes 121_1 to 121_R may serve as common electrodes. Furthermore, when the electronic device 100 operates in the touch mode, the first touch electrodes 121_1 to 121_R may serve as sensing electrodes for touch control. That is, the first touch electrodes may be shared as common electrodes.

[0073] Alternatively, in one embodiment, the first touch module 120 may be external, which means that the touch module is externally mounted on the display module. That is, the touch electrodes and the display electrodes are arranged in different panels (or modules). The first touch module 120 includes a plurality of first touch electrodes 121_1 to 121_R, but does not include display electrodes, that is, does not include a display layer 122. The display module is arranged in the first touch area 101, and the display layer 122 may be included in the display module. In detail, the display module includes a display layer 122, the display layer 122 includes a plurality of display electrodes 122_1 to 122_M, and the display module and the first touch module 120 are separate different modules (or panels). For example, the first touch module 120 is a touch panel, the display module is a display panel, and the display panel includes a display layer 122. And the shape and configuration position of the first touch electrodes 121_1 to 121_R are not limited to those shown in the drawings, but may be, for example, a rhombus, a square, or a rectangle. Similarly, the relative structural relationship between the second touch module 130 and the display electrode can be in-cell touch, on-cell touch, or out-cell touch, which can be referred to the relevant content of the first touch module 120 and will not be repeated here.

[0074] In this embodiment, the second touch module 130 is a plug-in type, for example, and can be a virtual touch module to implement virtual buttons (for example Fig.12 Alternatively, the second touch module 130 may also include a physical button, a knob or a slider (eg Fig.12 The physical button 6031 and multiple sliders 6032 are shown).

[0075] like Figure 1As shown, in this embodiment, the integrated chip 110 can drive (or process) at least one of the first touch electrodes 121_1-121_R and at least one of the second touch electrodes 131_1-131_N. The integrated chip 110 can be electrically connected to at least one of the first touch electrodes 121_1-121_R through the first touch signal line 104 to receive the first touch signal TS1 transmitted by at least one of the first touch electrodes 121_1-121_R. The integrated chip 110 can be electrically connected to at least one of the second touch electrodes 131_1-131_N through the second touch signal line 105 to receive the second touch signal TS2 transmitted by at least one of the second touch electrodes 131_1-131_N. The integrated chip 110 can process the first touch signal TS1 transmitted by at least one of the first touch electrodes 121_1-121_R, and can process the second touch signal TS2 transmitted by at least one of the second touch electrodes 131_1-131_N. Furthermore, the integrated chip 110 can be electrically connected to at least one of the display electrodes 122_1 to 122_M through the display signal line 106, and drive at least one of the display electrodes 122_1 to 122_M to achieve a display function. To simplify the drawings, the first touch signal line 104 and the display signal line 106 are represented by one line, but this is not intended to limit the present invention. According to some embodiments, the first touch signal line 104 and the display signal line 106 can be the same signal line or different signal lines. According to some embodiments, the integrated chip 110 can drive a plurality of first touch electrodes 121_1 to 121_R, a plurality of second touch electrodes 131_1 to 131_N, and a plurality of display electrodes 122_1 to 122_M.

[0076] In this embodiment, the first touch electrodes 121_1 to 121_R and the second touch electrodes 131_1 to 131_N can be used to implement the same or different touch mechanisms, and the integrated chip 110 can be controlled separately according to the touch mechanisms of the first touch electrodes 121_1 to 121_R and the second touch electrodes 131_1 to 131_N. For example, the first touch electrodes 121_1 to 121_R can be resistive or capacitive touch electrodes, and the second touch electrodes 131_1 to 131_N can be electrodes of physical buttons, knobs, or sliders, but the present disclosure is not limited thereto.

[0077] The first touch module 120 and the second touch module 130 may be disposed on the same substrate or on different substrates. Figure 1In the embodiment, the second touch area 102 and the circuit configuration area 103 may be continuous areas or separate areas. For example, the second touch area 102 and the circuit configuration area 103 are separate areas, and the second touch area 102 and the circuit configuration area 103 may be in different substrates. For example, the circuit board B1 may include the circuit configuration area 103, and the second touch module 130 may be disposed on a substrate different from the circuit board B1.

[0078] In this embodiment, the first touch module 120 and the second touch module 130 can be disposed on different substrates, and the first touch electrodes 121_1 to 121_R of the first touch module 120 and the second touch electrodes 131_1 to 131_N of the second touch module 130 are respectively disposed in the first touch area 101 and the second touch area 102, and are independently driven by the integrated chip 110. In other words, the first touch module 120 and the second touch module 130 can be formed as separate touch modules, so as to be independently operated to realize the touch functions of their respective corresponding touch areas.

[0079] Specifically, the integrated chip 110 can determine whether the first touch signal TS1 is a real touch signal. When the first touch signal TS1 is a real touch signal, the integrated chip 110 can report the point and store the first image. The integrated chip 110 can determine whether the second touch signal TS2 is a real touch signal. When the second touch signal TS2 is a real touch signal, the integrated chip 110 can report the point and store the second image. The first image and the second image are used to represent the touch coordinate information in the first touch area 101 and the second touch area 102. The integrated chip 110 can send the first image, the second image and the device information content of the human-machine interface of the related module to the back-end host chip (not shown, which can be electrically connected to the integrated chip 110) for use, so as to execute the corresponding function. According to some embodiments, the electronic device can be set in a vehicle, and the host chip can be a vehicle host chip. For example, the electronic device may include a vehicle host chip, and the integrated chip 110 may send the first image, the second image, and device information of the human-machine interface of the related module to the back-end vehicle host chip for use in executing corresponding functions.

[0080] Figure 2 is a circuit diagram of an electronic device according to an embodiment of the present disclosure. Figure 2In this embodiment, the electronic device 100 includes an integrated chip 110, a first touch module 120 and a second touch module 130. The integrated chip 110 may include a processing circuit 111, a microcontroller unit (MCU) 112 and a timing controller (TCON) 113. The processing circuit 111 is electrically connected to the microcontroller 112 and the timing controller 113. The processing circuit 111 may include a first processing unit 1111 and a second processing unit 1112. The first processing unit 1111 is electrically connected to the first touch module 120. The second processing unit 1112 is electrically connected to the second touch module 130. In this embodiment, the first processing unit 1111 may be a touch and display driver integration (TDDI). The second processing unit 1112 may be a touch sensing chip. The processing circuit 111 can communicate with the microcontroller 112 and the timing controller 113 via a serial peripheral interface (SPI) or a general-purpose input / output (GPIO) pin.

[0081] In this embodiment, the timing controller 113 is used to provide a timing signal CS to the processing circuit 111. The processing circuit 111 can obtain the timing signal CS from the timing controller 113, so that the first processing unit 1111 and the second processing unit 1112 can drive the first touch module 120 and the second touch module 130 according to the timing signal CS. The first processing unit 1111 and the second processing unit 1112 can respectively handshake with the microcontroller 112 by transmitting a synchronization signal. The first processing unit 1111 can be used to drive the first touch module 120 and a plurality of display electrodes disposed in the same touch area as the first touch module 120. For example, referring to Figure 1 and Figure 4 The first processing unit 1111 can be used to drive the first touch control electrodes 121_1 to 121_R of the first touch control module 120 and the display electrodes 122_1 to 122_M disposed in the same first touch control area 101 as the first touch control module 120 . The second processing unit 1112 can be used to drive the second touch control module 130 .

[0082] like Figure 2As shown, specifically, the first processing unit 1111 can obtain the first touch coordinates according to the first touch signal TS1 provided by the first touch module 120, and the second processing unit 1112 can obtain the second touch coordinates according to the second touch signal TS2 provided by the second touch module 130. The first processing unit 1111 can send the first raw data with the first touch coordinates to the microcontroller 112, and the second processing unit 1112 can send the second raw data with the second touch coordinates to the microcontroller 112. The microcontroller 112 can synthesize the first raw data with the first touch coordinates and the second raw data with the second touch coordinates, and generate unified touch sensing data to report to the vehicle host chip (not shown, which can be electrically connected to the integrated chip 110), so that the vehicle host chip can execute or trigger the corresponding function according to the touch result. In addition, the electronic device 100 of this embodiment can effectively save chip space by driving multiple touch modules (i.e., the first touch module 120 and the second touch module 130) through the integrated chip 110.

[0083] Figure 3 is a circuit diagram of an electronic device according to an embodiment of the present disclosure. Figure 3 The circuit configuration of the electronic device 100 disclosed in the present invention can also be implemented as follows Figure 3 Compared to Figure 2 In this embodiment, the first processing unit 1111 can also be externally provided outside the integrated chip 110, implemented in the form of an independent chip, and electrically connected between the first touch module 120 and the integrated chip 110, and drive the first touch module 120 and a plurality of display electrodes disposed in the same touch area as the first touch module 120, so as to obtain the first touch signal TS1 provided by the first touch module 120. In addition, in this embodiment, the second processing unit 1112 can also be externally provided outside the integrated chip 110, implemented in the form of an independent chip, and electrically connected between the second touch module 130 and the integrated chip 110, and drive the second touch module 130, so as to obtain the second touch signal TS2 provided by the second touch module 130. Therefore, the electronic device 100 of this embodiment can drive different touch modules respectively through different processing units.

[0084] Figure 4 is a circuit diagram of an electronic device according to an embodiment of the present disclosure. Figure 4 The circuit configuration of the electronic device 100 disclosed in the present invention can also be implemented as follows Figure 4 In this embodiment, the electronic device 100 includes an integrated chip 110, a first touch module 120, and a second touch module 130. In this embodiment, the integrated chip 110 may include Figure 2The first processing unit 1111 and the second processing unit 1112 described in the embodiment are used to respectively drive the first touch module 120 and the second touch module 130. The integrated chip 110 is electrically connected between the vehicle host chip 140 and the first touch module 120, and is also electrically connected between the vehicle host chip 140 and the second touch module 130.

[0085] However, unlike Figure 2 In the embodiment, the vehicle host chip 140 of the embodiment includes a microcontroller 112 and a timing controller 113. Specifically, the integrated chip 110 can obtain the first touch coordinates according to the first touch signal TS1 provided by the first touch module 120, and can obtain the second touch coordinates according to the second touch signal TS2 provided by the second touch module 130.
