Touch electronic device capable of changing the operation direction

The invention relates to a touch electronic device, in particular to a touch electronic device capable of changing a direction of a touch operation according to a display direction of a display screen.

Please refer to "Note 1", which is a notebook computer 2 with a touch panel 1 in the prior art. The touch panel 1 can be touched to generate a touch track and transmitted to the system circuit of the notebook computer. After the touch track is processed by the system circuit, an operation direction is generated to move a cursor located on the display screen 3. The touch panel 1 has a touch coordinate system (X, Y), and the display screen 3 has a display coordinate system (X', Y'). The horizontally-written letter "ABCD" shown in "Fig. 1" is arranged in the order of the horizontal direction of the display screen 3, and the arrangement direction of the letter "ABCD" in the horizontal direction is parallel to the horizontal axis X' of the display coordinate. Secondly, the touch coordinate system (X, Y) of the touch panel 1 directly corresponds to the display coordinate system (X', Y'), and is performed on the touch panel 1 along the horizontal axis X of the touch coordinate. The cursor can be moved along the display coordinate horizontal axis X' on the display screen 3, or an operation instruction corresponding to the display coordinate horizontal axis X' can be generated; the movement along the vertical axis Y of the touch coordinate can be performed on the touch panel 1 On the display screen 3, the cursor is moved along the display coordinate vertical axis Y', or an operation command corresponding to the display coordinate vertical axis Y' is generated.

Referring to "Fig. 2", in fact, as the display direction of the display changes, the display direction of the display screen 3 can also be changed to match the display direction of the display, that is, the display direction is changed, so that the bottom edge of the display screen 3 corresponds. On the side of the display facing down. Therefore, the display coordinate system (X', Y') changes accordingly, and the horizontal writing letter "ABCD" changes the direction of display and arrangement as the direction of the display screen 3 changes. The arrangement direction of the writing letter "ABCD" is parallel to the horizontal axis X' of the display coordinate after the turning. For the notebook computer, especially the notebook computer that wants to carry the Microsoft Windows 7 operating system (W7), it can convert the horizontal display screen into a straight display screen through the functions carried in the operating system. At this time, the user of the W7 can change the holding mode of the notebook computer 2, hold the notebook computer 2 in a book-like manner, and let the display screen 3 be displayed in a straight manner like a normal paper. At this time, the display coordinate system (X', Y') is turned by 90 degrees so that the display direction of the display screen 3 can be turned by 90 degrees, such as the turning of the horizontally written letter "ABCD" in the display screen 3. However, the touch coordinate system (X, Y) has not changed or been transposed relative to the notebook. At this time, the touch coordinate horizontal axis X is parallel to the display coordinate vertical axis Y', and the touch coordinate vertical axis Y is parallel to the display coordinate horizontal axis X'. However, the touch coordinate system (X, Y) of the touch panel 1 still directly corresponds to the display coordinate system (X', Y'), and the operation along the horizontal axis X of the touch coordinate still corresponds to the display coordinate horizontal axis X. The operation along the vertical axis Y of the touch coordinate still corresponds to the vertical axis Y' of the display coordinate. If the moving cursor is used as an example, after the touch panel 1 generates a touch operation direction, the actual moving direction of the cursor will be at an angle of 90 degrees from the touch operation direction on the touch panel.

In the state shown in FIG. 2, the user will have a misplaced feeling on the touch panel 1, so that the user cannot intuitively operate the touch panel 1. Therefore, the user cannot use the touch panel 1 to perform complicated input and operating.

In the prior art, after the display direction of the display screen is changed, the user cannot intuitively operate the touch panel. The present invention provides a touch electronic device capable of changing the operation direction, which can be changed in the display direction of the display screen. After that, the operation direction generated by the track signal outputted by the touch panel is also converted, and the operation direction of the touch panel can correspond to the display direction of the display screen, so that the user can intuitively use the touchpad after the display direction is changed. .

The invention provides a touch electronic device capable of changing an operation direction, comprising a display screen, a system circuit, a touch panel, an embedded controller and an operation direction conversion software. The display screen is configured to receive an output image and display a display screen; the system circuit is configured to generate an output image, and the system circuit can receive a steering signal, change the output image, change the display direction of the display screen, and issue a system event. The touchpad is used to be contacted to output a touch track; the embedded controller receives the touch track to generate an operation direction of the touchpad for transmission to the system circuit. The operation direction conversion software is executed in the system circuit for detecting system events, and converting the operation direction of the touch panel so that the operation direction corresponds to the display screen.

The invention converts the display direction of the display screen and simultaneously changes the operation direction of the touch panel so that the operation direction corresponds to the display direction. Therefore, the present invention solves the problem that the touch panel cannot be intuitively operated by the user due to the display direction change of the display screen in the touch electronic device.

Please refer to FIG. 3 and FIG. 4 , which illustrate a touch electronic device 100 capable of changing an operation direction according to a first embodiment of the present invention. The touch control device 100 includes a display screen 110, a system circuit 120, a touch panel 130, an embedded controller 140, and an operation direction conversion software 150. The touch electronic device 100 is generally a notebook computer or other electronic device having the operation function of the touch panel 130 and the display screen 110.

Referring to Figure 4, system circuit 120 is used to generate an output image. The system circuit 120 includes a central processing unit 121, a north bridge wafer 122, a display wafer 123, and a south bridge wafer 124. The central processing unit 121, the north bridge wafer 122, the display wafer 123, and the south bridge wafer 124 shown in the figure are separately drawn, but in fact, they can be arbitrarily integrated into a single wafer, for example, the central processing unit 121 and the north bridge wafer 122 are integrated into A single wafer, even further combined with central processor 121, north bridge wafer 122, and display wafer 123. The central processing unit 121 is configured to load the operating system and the program to generate an output image, which is transmitted to the display wafer 123 through the north bridge wafer 122, and an output image is generated by the display wafer 123 to the display screen 110.

Referring to the "Fig. 3" and "Fig. 4", after the display 110 receives the output image generated by the display chip 123 of the system circuit 120, a display screen 111 is displayed on the display screen 110.

Referring to "Figure 5", "Picture 6", "Picture 7" and "Figure 8", a display coordinate system (X', Y') can be defined on the display screen 111 to display the coordinate system (X). ', Y') includes a display coordinate horizontal axis X' and a display coordinate vertical axis Y'. As the display direction of the display screen 110 changes, the system circuit 120 can receive the steering signal, change the output image, cause the display screen 111 to change its display direction, and re-define the display coordinate system (X', Y'). And turn. After the display screen 111 changes its display direction, the system circuit 120 issues a system event to notify each software or hardware to perform the corresponding action.

Referring to "Fig. 3" and "Fig. 4", the touch panel 130 is connected to the embedded controller 140 via a PS/2 (personal system/2) interface. The touch panel 130 is used to be contacted to output a touch track, and is transmitted to the embedded controller 140. Then, the embedded controller 140 generates an operation direction of the touch panel 130 for transmission to the south bridge wafer 124 of the system circuit 120. And then transmitted to the central processing unit 121 for corresponding operations. The surface of the touch panel 130 defines a touch coordinate system (X, Y), and the touch coordinate system (X, Y) includes a touch coordinate horizontal axis X and a touch coordinate vertical axis Y. The embedded controller 140 generates an operation direction according to the touch track, and the operation direction has a correspondence relationship with the touch coordinate system (X, Y).

Referring to "5th", "6th", "7th" and "8th", in order to make the operation direction of the touch panel 130 correspond to the display coordinate system (X' of the display screen 111, Y'), the touch coordinate horizontal axis X needs to be parallel to the display coordinate horizontal axis X', so that the user can normally use the touch panel 130.

The system circuit 120 normally performs the operation direction conversion software 150 so that the operation direction conversion software 150 is resident in the operating system (for example, Microsoft Windows 7 referred to as W7). The operation direction conversion software 150 can be a separate program for further processing the data exchange between the driver of the touch panel 130 and the operating system, and can also be a piece of code among the drivers of the touch panel 130.

See "Figure 4", when the user passes the operating system (for example The built-in function of Microsoft Windows 7) directly causes the central processing unit 121 to change the direction of the output image, so that after the display screen 111 in the display screen 110 is switched to the display direction, the display screen 111 is changed from the original horizontal picture to the straight picture. Thereafter, the display coordinate system (X', Y') can be redefined with the display screen 111. At the same time, the system circuit 120 also issues a system event to notify all executing programs to change with the conversion of the display direction.

At the same time, as shown in Figure 5, Figure 6, Figure 7, and Figure 8, when the operation direction conversion software 150 detects a system event, the operation direction conversion software 150 switches the touch. The operation direction of the board 130 causes the operation direction of the touch panel 130 to be switched in accordance with the display direction of the display screen 110. After the operation direction conversion software 150 obtains the conversion angle of the display direction of the display screen 110 in the system event (right turn 90 degrees, left turn 90 degrees or turn 180 degrees), the operation direction conversion software 150 switches according to the conversion angle of the display direction. The operation direction of the control board 130 is such that the converted operation direction corresponds to the new display direction. The steering direction of the touchpad 130 is such that the touch coordinate system (X, Y) can be redefined, corresponding to the display coordinate system (X', Y'), so the touch coordinate horizontal axis X is again parallel to The display coordinate axis X of the display screen 111 allows the user to intuitively use the touch panel 130.

Referring to FIG. 3 and FIG. 4, an embodiment of the present invention further provides a setting button 160 that is directly electrically connected to the system circuit 120 or indirectly connected to the system circuit 120 through the embedded controller 140. The setting button 160 can be a single independently set button and a hot key set on the keyboard. The setting button 160 is used to be pressed to generate the steering signal to the system circuit 120, so that the operating system is triggered, and the system circuit 120 is converted by the built-in function of the operating system (for example, Microsoft Windows 7) or the driver of the display chip 123. The display direction of the screen 111 is displayed. According to the setting of the operating system or the driver, the steering signal sent by the setting button 160 can be defined by a specific rotation direction and a rotation angle. For example, the setting button 160 is pressed once to make the display of the display screen 111. The direction is changed according to the existing display direction. Turn right 90 Turn 90 degrees to the left to allow the user to select the angle to be converted. The user can press the set button 160 once, twice or three times according to the angle of rotation required to turn right (or left) by 90 degrees, 180 degrees, 270 degrees. After accepting the steering signal of the setting button 160, the system circuit 120 transmits a system event in addition to the display direction of the display screen 111, so that the operation direction switching software 150 switches the operation direction of the touch panel 130.

In addition to using the setting button 160, a program interface menu may be provided in the driver of the display chip 123 or in the operating system, and displayed on the display screen 111 after being opened for the user to select the display screen 111. Show direction. Each time the setting button 160 is pressed, the display direction of the display screen 111 can be rotated toward a specific direction and angle (for example, left/right rotated by 90 degrees), and the program interface menu can list multiple conversion options, each of which has a plurality of conversion options. It has a rotation direction and a rotation angle, for example, right turn 90 degrees, left turn 90 degrees, turn 180 degrees, right turn 270 degrees, left turn 270 degrees. After the user selects one of the plurality of conversion options, the operating system issues the steering signal (including the rotation direction and the rotation angle) to the system circuit 120 according to the conversion option, so that the system circuit 120 converts the display direction of the display screen 111. And issue the system event.

Referring to "figure 5", "figure 6", "figure 7" and "8th", regardless of how the display screen 111 changes its display direction, the operation direction switching software 150 changes the touch panel 130 accordingly. The operation direction is such that the horizontal axis X of the touch coordinate in the touch coordinate system (X, Y) is again parallel to the horizontal axis X' of the display coordinate. At this time, the operation direction corresponding to the touch track generated by the touch panel 130 can be corresponding to the setting direction of the display screen 111, so that after the display screen 110 and the touch panel 130 are simultaneously changed in the setting direction, the user still The touchpad 130 can be operated intuitively.

In addition to generating a track signal or providing a button mode or scrolling a file, the touch panel 130 of the present invention also has the aforementioned button mode or scroll file function, such as "9A". Figure "and Figure 9B". In addition to generating a track signal to be converted into an operation direction, the touch panel 130 of the present invention also has additional functions such as a button mode or a scroll mode. These additions The function is also switched with the direction of operation of the trackpad 130, and is changed by the operation direction switching software 150 to change its defined block or corresponding output.

As shown in FIG. 9A and FIG. 9B, a touch area 132 is defined on the touch panel 130 for being touched to output a scrolling direction. The scrolling area 132 is adjacent to one side of the touch panel 130 and parallel to one of two orthogonal axes of the touch coordinate system (X, Y). Generally, the scrolling area 132 is touched to generate a scrolling direction, and the display area of the file file is scrolled up and down. Therefore, the scrolling area 132 is generally disposed parallel to the vertical axis Y of the touch coordinate, and is located on the touchpad. The right side of 130 (can also be changed to the left side according to the dominant hand). After the operation direction of the touch panel 130 and the display direction of the display screen 111 are converted, the operation direction conversion software 150 also dynamically changes the defined position of the scroll area 132 so that the scroll area 132 is located on the touch panel 130 adjacent to the right side. In the region of the side, the direction of scrolling on the scrolling zone 132 is simultaneously changed so that the scrolling direction corresponds to the display direction.

In addition, through the function setting of the embedded controller 140 or the system circuit 120, the touch panel 130 can be provided with a button mode, and when the user touches the surface of the touch panel 130 quickly, for example, the touch panel is quickly touched. The surface of the 130 is used twice, and the central processing unit 121 of the system circuit 120 can regard the action of the quick touch as the function of the left mouse button, so that the touch panel 130 can perform the function of the button 131. Since the button mode is judged only by whether the surface of the touch panel 130 is quickly positioned twice, regardless of the direction or coordinate change, after the operation direction of the touch panel 130 and the display direction of the display screen 111 are converted, the user The button mode can still be used according to the original operation mode.

The conversion of the display direction of the display screen 111 can be automatically switched by the user by manually switching the conversion or sensing. During the manual switching, the user can send a steering signal to the system circuit 120 through the operation of the program interface menu or the setting button 160 displayed on the display screen 111 to drive the system circuit 120 to switch the display direction of the display screen 111. The system circuit 120 then issues a system event, causing the operation direction conversion software 150 to switch the operation direction of the touch panel 130 so that the operation direction of the touch panel 130 corresponds to the new display direction.

As shown in FIG. 10, a touch electronic device 100 that can change the operation direction according to the second embodiment of the present invention includes a display screen 110, a system circuit 120, a touch panel 130, and an embedded The controller 140 and an operation direction conversion software 150.

The display screen 110, the system circuit 120, the touch panel 130, the embedded controller 140, and the operation direction conversion software 150 of the second embodiment are substantially the same as the first embodiment, with the difference that the second embodiment senses in one direction. The device 170 replaces the setting button or the interface setting menu for automatic switching. The direction sensor 170 is, for example, a gravity sensor (G-sensor) for detecting the direction in which the display screen 110 is disposed. Taking the gravity sensor as an example, the gravity sensor can detect the direction of gravity, thereby obtaining a direction detection result for the operating system to determine the current display direction of the display screen 110 to determine the conversion angle required for displaying the display screen 111. And send a turn signal.

The direction sensor 150 is directly electrically connected to the system circuit 120 or indirectly connected to the system circuit 120 through the embedded controller 140 for transmitting the direction detection result to the operating system, and the operating system sends a steering signal according to the result. The system circuit 120 is provided for the system circuit 120 to switch the display direction of the display screen 131 and issue a system event.
