[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] The terms "first", "second", etc. of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of one type, and the number of objects is not limited, for example, the first object can be one or more. In addition, "or" in the present application represents at least one of the connected objects. For example, "A or B" covers three schemes, namely, Scheme 1: including A but not including B; Scheme 2: including B but not including A; Scheme 3: including both A and B. The character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0044] In the technical solution of the present disclosure, words such as “connect”, “couple” or “connected” are not limited to physical or mechanical connections, but may include electrical connections.

[0045] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0046] The embodiment of the present invention provides a touch module, see Figure 1 As shown, it includes a touch area 100, and the touch module includes:

[0047] A plurality of first electrodes 10 and a plurality of second electrodes 20 are arranged in the touch control area 100, and the first electrodes 10 and the second electrodes 20 are cross-insulated and arranged; in the extension direction of the first electrodes 10, the touch control area 100 is divided into at least two touch control sub-areas 101, and each of the first electrodes 10 is disconnected in the area between two adjacent touch control sub-areas 101, and is divided into at least two sections;

[0048] There are a plurality of first electrode wires 11 , and each section of each first electrode 10 is connected to the touch control driving chip 30 via one of the first electrode wires 11 .

[0049] In some embodiments of the present invention, optionally, the first electrode 10 is a transmitting electrode (TX) and the second electrode 20 is a sensing electrode (RX). Of course, in some embodiments, optionally, the first electrode 10 may also be a sensing electrode (RX) and the second electrode 20 may be a transmitting electrode (TX). A coupling capacitor is generated at the intersection of the driving electrode and the sensing electrode. When a finger touches the touch device, the coupling capacitor at the touch position changes. The touch position of the finger can be determined by detecting the change in the coupling capacitor through the touch driving chip 30 (i.e., IC).

[0050] In the embodiment of the present invention, the touch area 100 is divided into at least two touch sub-areas 101 in the extension direction of the first electrode 10. The touch function of some touch sub-areas 101 can be turned off, specifically, the electrical connection between the segment of the first electrode 10 in the touch sub-area 101 and the touch driving chip 30 is cut off, thereby turning off the touch function of the touch sub-area 101.

[0051] It should be noted that in some optional embodiments, the touch module is applied to the screen of the vehicle cockpit, and the screen (also called a long strip screen) extends from the main driver's seat to the co-driver's seat along the width direction of the vehicle body.

[0052] In the above embodiment, the touch module of the embodiment of the present invention is used to adjust the touch function of the screen according to different driving modes. Figure 2aAs shown, during the driving process of the vehicle, the driver operates the steering wheel and does not touch the screen. The touch function of the touch sub-area 101 located at the driver's seat can be turned off to reduce the energy consumption of the screen. In particular, for vehicles whose driving force includes electric drive, reducing the energy consumption of the screen is also beneficial to improving the vehicle's cruising range. Correspondingly, during the driving process of the vehicle, the touch function of the touch sub-area 101 located at the co-pilot seat can be turned on to ensure that the passenger in the co-pilot seat can interact with the vehicle through the touch screen, such as turning on or off the air conditioner, playing music, playing videos, etc.

[0053] For example, in some models, the vehicle adopts a retractable steering wheel design to improve the efficiency of space utilization in the vehicle or adapt to the autonomous driving mode. The retractable design means that when the vehicle is in the autonomous driving mode or parked, the steering wheel can be automatically folded or retracted to provide more space for the driver. Figure 2b As shown, when the steering wheel is retracted, the touch functions of the touch sub-area 101 located at the driver's seat and the touch sub-area 101 located at the co-pilot seat are both turned on, which facilitates the driver and the passenger located at the co-pilot seat to interact with the vehicle computer through the touch screen. It should be noted that the solution of retracting the steering wheel when the vehicle is in the automatic driving mode should meet the provisions of laws and regulations on automatic driving and comply with traffic rules.

[0054] In an embodiment of the present invention, the touch module includes: a plurality of first electrodes 10 and a plurality of second electrodes 20, which are arranged in the touch area 100, and the first electrodes 10 and the second electrodes 20 are cross-insulated; in the extension direction of the first electrode 10, the touch area 100 is divided into at least two touch sub-areas 101, and each of the first electrodes 10 is disconnected in the area between two adjacent touch sub-areas 101 and is divided into at least two sections; a plurality of first electrode wirings 11, and each section of each of the first electrodes 10 is connected to the touch driving chip 30 through one of the first electrode wirings 11.

[0057] See also Figure 3 As shown, Figure 3The diagram illustrates the connection relationship between a touch driver chip 30 and two segments of a first electrode 10 located in two touch sub-regions 101 . The touch driver chip 30 can control the connection or disconnection between each segment of the first electrode 10 and the touch driver chip 30 .

[0058] In some embodiments of the present invention, optionally, see Figure 3 As shown, the touch switching circuit 40 includes: a first switch 41 and a diode 42;

The moving end 411 is used to connect to the touch control driving chip 30 .

[0061] It should be noted that see Figure 4 As shown, the curve with arrows illustrates the signal transmission path. When the moving end 411 is connected to the fixed end 412 connected to the input end of the diode 42, the diode 42 is turned on, the touch driving chip 30 and the two sections of the first electrode 10 are both turned on, and the touch functions of the two touch sub-areas 101 are turned on. Figure 5 As shown, the curve with arrows illustrates the signal transmission path. When the moving end 411 is connected to the fixed end 412 connected to the output end of the diode 42, the diode 42 is turned off, and the touch driving chip 30 is connected to the Figure 5 A section of the first electrode 10 on the left side is disconnected, and the touch driver chip 30 is connected to Figure 5 A section of the first electrode 10 on the right side is turned on. Figure 5 The touch function of the touch sub-area 101 on the left side is turned off. Figure 5 The touch function of the touch sub-area 101 on the middle right is turned on.

[0062] In the embodiment of the present invention, the connection or disconnection between each segment of the first electrode 10 and the touch driving chip 30 is controlled by switching the movable end 411 of the first switch 41 between the two fixed ends 412, so that the circuit layout is simple and the reliability is high.

[0067] PIN diode is a special type of diode widely used in photodetectors, radio frequency (RF) and microwave circuits. The name of PIN diode comes from its structure: a combination of P-type (positive) semiconductor, I-type (intrinsic) semiconductor and N-type (negative) semiconductor. PIN diode has the advantages of being able to effectively process high-frequency signals, being highly sensitive to light, being suitable for optoelectronic applications, and having low noise characteristics.
