The third sensor 117 may be a track sensor, disposed corresponding to the third touch area 116 and coupled to the controller 120 , and used for generating a track signal to transmit to the controller 120 according to the received touch gesture. However, in other embodiments, the first sensor 113 , the second sensor 115 and the third sensor 117 may also be other forms of pressure sensors, or may also be capacitive or resistive sensing device, not limited by this.

Therefore, the first sensor 113 can be used to receive a pressed area of a first touch input. The second sensor 115 can be used to receive a second touch input, and the third sensor 117 can be used to receive a third touch input.

It is worth mentioning that, in this embodiment, the first touch area 112 , the second touch area 114 and the third touch area 116 can be activated or deactivated according to different usage states. The method of operation can be referred to the method of FIG. 3 .

The electronic device 100 of this embodiment may adopt the following steps. First, the controller 120 determines the input state of the electronic device 100 . Then, the controller 120 enables the first touch area 112 and disables the second touch area 114 and the third touch area 116 based on the pressure area greater than or equal to a predetermined value. Alternatively, the controller 120 enables the first touch area 112 , the second touch area 114 and the third touch area 116 based on the pressure area being smaller than the predetermined value. In this embodiment, the default value may be 3 square millimeters to distinguish whether the first touch area 112 receives the touch of the stylus pen or the touch of a finger, but the present disclosure is not limited to this.

Specifically, in this embodiment, the first state and the second state are determined by the pressure-receiving area. For example, the pressure-receiving area of the finger touch and the stylus touch are different, and the use state can be distinguished, but the first state The way of judging the state and the second state is not limited by this. In other embodiments, the first state and the second state may also be distinguished by Bluetooth pairing, specific gestures, or other methods.

In detail, FIG. 3 is a schematic diagram of the electronic device of FIG. 1A in a first state. Referring to FIG. 3 , in the first state, for example, the user touches with a finger. If the user touches the first touch area 112 with a finger, the pressure area received by the first sensor 113 will be greater than or equal to a predetermined value because the area pressed by the finger is larger, and the controller 120 determines/identifies for the first state. At this time, the controller 120 enables the first touch area 112 and disables the second touch area 114 and the third touch area 116 .

That is to say, in the first state, the electronic device 100 can only activate the first touch area 112, and the second touch area 114 and the third touch area 116 are not activated. The first touch area 112 is used as a general touch panel. In this way, the user's wrist or palm can be prevented from accidentally touching the second touch area 114 or the third touch area 116 .

4 and 5 are schematic diagrams of the electronic device of FIG. 1A in a second state. Referring to FIG. 4 and FIG. 5 , in the second state, for example, the user uses the touch pen 10 to touch. If the user touches the first touch area 112 with the stylus 10, since the tip of the stylus 10 has a small area, the pressure area received by the first sensor 113 is smaller than the preset value, and the control The controller 120 can determine/recognize the second state.

At this time, the controller 120 enables the first touch area 112 , the second touch area 114 or/and the third touch area 116 . That is to say, the electronic device 100 can activate the first touch area 112, the second touch area 114 and/or the third touch area 116 at the same time, so as to provide a large-area touch area for the user to operate, and similar Large trackpad.

It is worth mentioning that the difference from the conventional external touchpad is that in this embodiment, since the first touch area 112 , the second touch area 114 and the third touch area 116 are respectively controlled by the first sensing The sensor 113 , the second sensor 115 and the third sensor 117 sense, and the user can simultaneously input signals to the first touch area 112 , the second touch area 114 or/and the third touch area 116 . Therefore, when the controller 120 enables the first touch area 112 , the second touch area 114 and the third touch area 116 , the user can simultaneously input multiple commands in the multiple touch areas to provide more functions .

As shown in FIG. 5 , when the first touch area 112 , the second touch area 114 and the third touch area 116 are enabled at the same time, the first touch area 112 and the second touch area 114 can be used to receive the first touch area 112 and the second touch area 114 . For touch input and second touch input, the third touch area 116 can be used to receive a third touch input, wherein the first touch input and the second touch input include a handwriting input from the stylus 10, and the third touch input The three-touch input includes a touch gesture.

Specifically, the user can use the stylus 10 to write information in the second touch area 114 , and at the same time use the fingers of the other hand to input touch gestures in the third touch area 116 . For example, the user can change the distance between the thumb and the index finger on the third touch area 116 to zoom in or zoom out the screen of the screen 152 . Alternatively, the user can move the screen 152 by panning with two or three fingers. In other words, the user can use the stylus 10 to draw a picture, and use gestures to move the picture or zoom in on the picture for more detailed drawing. That is to say, the third touch area 116 can be used exclusively for sensing gestures to perform command operations, but not limited thereto.

Certainly, the form, manner and position of the input command of the first sensor 113 , the second sensor 115 and the third sensor 117 are not limited to the above. In other embodiments, a left-handed user can also use the stylus 10 to write information in the third touch area 116 or/and the first touch area 112 while using a finger in the second touch area 114 to enter the command.

In addition, in other embodiments, the user can also input different commands to the first touch area 112 and the second touch area 114 at the same time, or input different commands to the first touch area 112 and the third touch area 116 at the same time . If multiple people operate, a first command can also be input to the first touch area 112 , a second command can be input to the second touch area 114 , and a third command can be input to the third touch area 116 at the same time. For example, multiple people use multiple stylus 10 to draw pictures in different touch areas at the same time, and these operations can be displayed on the screen at the same time.

It should be noted that the method of judging the first state and the second state is not limited by the pressure area. In other embodiments, since the tip area of the stylus 10 is small, the pressure at a single point is relatively large. The magnitude of the pressure value is judged to distinguish whether it is the finger or the stylus 10 touching.

In another embodiment, the electronic device 100 may also display on the screen 152 of the second body 150 to execute the normal touch mode or the drawing mode of the stylus 10 for the user to select, and the controller 120 may The current state is identified as the first state or the second state according to the content selected by the user.

As shown in FIG. 4 , in this embodiment, the electronic device 100 may optionally include a Bluetooth module 130 that is electrically connected to the controller 120 . The stylus 10 (electronic component) includes a Bluetooth component 12 . In one embodiment, the electronic device 100 detects the pairing signal sent by the Bluetooth component 12 through the Bluetooth module 130 , and when the controller 120 determines that the pairing signal matches the electronic device 100 , the controller 120 can determine the second state , and the first touch area 112 and the second touch area 114 or/and the third touch area 116 are enabled. In one embodiment, the first state may also be that the Bluetooth module 130 does not receive the pairing signal, and the second state may also be that the Bluetooth module 130 has received the pairing signal. That is to say, the controller 120 of the electronic device 100 can determine whether the stylus 10 is approaching through wireless pairing such as Bluetooth, so as to disable or enable the second touch area 114 and/or the third touch area 116 . Of course, in other embodiments, the types of electronic components are not limited thereto.

In this embodiment, the light source assembly 140 is, for example, a combination of a light emitting diode and a light bar. The shape and range of the light bar correspond to the ranges of the first touch area 112 , the second touch area 114 and the third touch area 116 .

In one embodiment, the light source component 140 may also include a plurality of light emitting diodes, which are arranged on the boundary of the first touch area 112 , the second touch area 114 and the third touch area 116 , and the form of the light source component 140 is different. This is the limit.

In the present embodiment, the setting area of the light source element 140 corresponding to the first touch area 112 and the second touch area 114 is a light-transmitting area. That is to say, a casing 118 corresponding to the first touch area 112 and the second touch area 114 (the upper casing 118 of the first body 110 , commonly referred to as the C piece) is transparent. For example, light-colored pressure gram plates, transparent pressure gram plates or glass plates. As shown in FIG. 4 , when the electronic device 100 is activated and only the first touch area 112 is enabled, the controller 120 can instruct the light source assembly 140 to cause the light emitted by the light source assembly 140 to be defined on the casing 118 The range of the first touch area 112 . Therefore, the user can know the range of the first touch area 112 through the range of the light.

When the controller 120 determines the second state, the controller 120 enables the first touch area 112 , the second touch area 114 or/and the third touch area 116 , and the controller 120 can instruct the light source component 140 to enable the The light emitted by the light source assembly 140 simultaneously defines a range surrounding the first touch area 112 , the second touch area 114 or/and the third touch area 116 on the casing 118 . In this way, the user can conveniently know in which range different commands are to be input.

Of course, in other embodiments, the casing 118 can also be divided into the range of the first touch area 112 , the second touch area 114 and the third touch area 116 by printing. The identification methods of the ranges of the first touch area 112 , the second touch area 114 and the third touch area 116 are not limited to the above.

To sum up, the electronic device of the present disclosure can have a larger touch area by arranging the first touch area and the second touch area. In addition, when a pressure area received by the first sensor is greater than or equal to a predetermined value, such as a finger touch, the controller determines the first state. In order to avoid accidentally touching other touch areas, the controller The first touch area is enabled and the second touch area is disabled. When the pressure-receiving area received by the first sensor is smaller than the preset value, such as operating with a stylus, the controller determines that it is in the second state, which means that a larger touch area is required, and the controller enables the first A touch area and a second touch area receive touch input with a larger area of the touch area.
