Description

Touch electronic devices that change the direction of operation

technical field

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

Background technique

Please refer to FIG. 1 , which is a notebook computer 2 equipped with a touch panel 1 in the prior art. The touch panel 1 can be touched to generate a touch track, which is sent 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 on the display screen 3 . The touch panel 1 has a touch coordinate (X, Y), and the display screen 3 has a display coordinate (X', Y'). As shown in FIG. 1 , the horizontal writing letters "ABCD" are arranged sequentially along the horizontal direction of the display screen 3, and the arrangement direction of the horizontal writing letters "ABCD" is parallel to the display coordinate horizontal axis X'. Secondly, the touch coordinates of the touch panel 1 are (X, Y) directly corresponding to the display coordinates (X', Y'), so the movement along the horizontal axis X of the touch coordinates on the touch panel 1, The cursor can be moved along the horizontal axis X' of the display coordinates on the display screen 3, or an operation command corresponding to the movement of the horizontal axis X' of the display coordinates can be generated; the movement along the vertical axis Y of the touch coordinates on the touch panel 1 can be performed on the Move the cursor on the display screen 3 along the vertical axis Y' of the display coordinates, or generate an operation instruction for moving corresponding to the vertical axis Y' of the display coordinates. the

Referring to "Figure 2", in fact, as the orientation of the display changes, the display orientation of the display screen 3 can also be changed to match the orientation of the display, that is, the display orientation is changed so that the bottom edge of the display screen 3 corresponds to The side on which the monitor is set facing down. Therefore, the display coordinates (X', Y') change accordingly, and the above-mentioned horizontal writing letters "ABCD" just follow the change of the direction of the display screen 3, and change the direction of its display and arrangement. The arrangement direction of the written letters "ABCD" is parallel to the horizontal axis X' of the display coordinates after turning. For a notebook computer, especially a notebook computer intended to carry the Microsoft Windows 7 operating system (W7 for short), the horizontal display screen can be converted into a vertical display screen through the built-in function of the operating system. At this time, the user of the W7 can change the holding method of the notebook computer 2 to hold the notebook computer 2 in a manner similar to a book, and make the display screen 3 present a vertical display like ordinary paper. At this time, the display coordinates (X', Y') are rotated by 90 degrees, so that the display direction of the display screen 3 can be rotated by 90 degrees, such as the horizontal writing letter "ABCD" in the display screen 3. However, the touch coordinates (X, Y) are not changed or transposed relative to the notebook computer. At this time, the horizontal axis X of the touch coordinates is parallel to the vertical axis Y' of the display coordinates, and the vertical axis Y of the touch coordinates is parallel to the horizontal axis X' of the display coordinates. However, the touch coordinates of the touch panel 1 (X, Y) are still directly corresponding to the display coordinates (X', Y'), and the operation along the horizontal axis X of the touch coordinates still corresponds to the horizontal axis X of the display coordinates. '; The operation along the vertical axis Y of the touch coordinates still corresponds to the vertical axis Y' of the display coordinates. Taking moving the cursor 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. the

In the state shown in "Figure 2", the user will have a sense of misplacement for the touchpad 1, making the user unable to intuitively operate the touchpad 1, so the user will not be able to use the touchpad 1 for complex input and operations . the

Contents of the invention

In view of the known technology, after the display direction of the display screen is changed, the user cannot intuitively operate the touch panel. Afterwards, an operation direction generated according to the track signal output by the touch panel is also converted. The operation direction of the touch panel can correspond to the display direction of the display screen, so that the user can still use the touch panel intuitively after the display direction is changed. . the

The invention proposes a touch electronic device capable of changing the direction of operation, which includes a display screen, a system circuit, a touch panel, and an embedded controller. The display screen is used to receive an output image and display a display screen; the system circuit is used to generate the output image, and the system circuit can change the output image after receiving a turn signal to make the display screen change its display direction and send a system event. The touch panel is used to output a touch track when being touched; the embedded controller receives the touch track to generate an operation direction of the touch panel and send it to the system circuit. The system circuit is used for detecting system events and converting the operation direction of the touch panel so that the operation direction corresponds to the display screen. the

In the invention, along with the display direction of the display screen, the operation direction of the touch panel is simultaneously converted, so that the operation direction corresponds to the display direction. Therefore, the present invention solves the problem that the user cannot intuitively operate the touch panel due to the change of the display direction of the display screen in the touch electronic device. the

Detailed ways

Please refer to “ FIG. 3 ” and “ FIG. 4 ”, which are a touch electronic device 100 capable of changing the operating direction disclosed in the first embodiment of the present invention. The touch electronic device 100 includes a display screen 110 , a system circuit 120 , a touch panel 130 , an embedded controller 140 and an operation direction switching software 150 . The touch electronic device 100 is generally a notebook computer, or other electronic devices having both the operation function of the touch panel 130 and the display screen 110 . the

Referring to FIG. 4 , the system circuit 120 is used to generate an output image. The system circuit 120 includes a central processing unit 121 , a north bridge chip 122 , a display chip 123 and a south bridge chip 124 . Although the central processing unit 121, north bridge chip 122, display chip 123 and a south bridge chip 124 shown in the figure are drawn separately, they can be arbitrarily integrated into a single chip, for example, the central processing unit 121 and the north bridge chip 122 are integrated It is a single chip, and it is even further combined with a central processing unit 121 , a north bridge chip 122 and a display chip 123 . The central processing unit 121 is used to generate an output image after loading the operating system and programs, and transmit it to the display chip 123 through the north bridge chip 122 , and then the display chip 123 generates an output image to the display screen 110 . the

Referring to FIG. 3 and FIG. 4 , after the display screen 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 . the

Referring to "Fig. 5", "Fig. 6", "Fig. 7" and "Fig. 8", it can be defined on the display screen 111 that a display coordinate is (X', Y'), and a display coordinate is (X', Y' ) includes a display coordinate horizontal axis X' and a display coordinate vertical axis Y'. As the orientation of the display screen 110 changes, the system circuit 120 can change the output image after receiving a turn signal, so that the display screen 111 can change its display orientation, and the display coordinates (X', Y') can be redefined And turn. After the display screen 111 changes its display direction, the system circuit 120 sends a system event to notify various software or hardware to perform corresponding actions. the

Referring to FIG. 3 and FIG. 4 , the touch panel 130 is connected to the embedded controller 140 through an interface such as PS/2 (personal system/2). The touch panel 130 is used to be touched to output a touch track, which is sent to the embedded controller 140, and then the embedded controller 140 generates an operation direction of the touch panel 130 to be sent to the south bridge chip of the system circuit 120 124, and then send it to the central processing unit 121 for corresponding operations. The surface of the touch panel 130 can define a touch coordinate (X, Y), and the touch coordinate (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 there is a correspondence between the operation direction and the touch coordinates (X, Y). the

Referring to "Fig. 5", "Fig. 6", "Fig. 7" and "Fig. 8", in order to make the operation direction of the touch panel 130 correspond to the display coordinates of the display screen 111 being (X', Y'), touch The horizontal axis X of the control coordinates must be parallel to the horizontal axis X′ of the display coordinates so that the user can use the touch panel 130 normally. the

The system circuit 120 normally executes the operation direction conversion software 150, so that the operation direction conversion software 150 is resident in the operating system (such as Microsoft Windows 7 for short W7). The operating direction switching software 150 can be an independent program for further processing the data exchange between the driver program of the touch panel 130 and the operating system, or can be a piece of program code in the driver program of the touch panel 130 . the

Referring to "Figure 4", when the user uses the built-in function of the operating system (such as Microsoft Windows 7), the central processing unit 121 directly changes the direction of the output image, so that the display screen 111 in the display screen 110 changes the display direction Afterwards, after the display frame 111 changes from the original horizontal frame to the vertical frame, the display coordinates (X′, Y′) can be redefined along with the display frame 111 . At the same time, the system circuit 120 will also send out a unified event to notify all the programs in execution to change with the conversion of the display direction. the

Also refer to “ FIG. 5 ”, “ FIG. 6 ”, “ FIG. 7 ” and “ FIG. 8 ”, when the operation direction conversion software 150 detects a system event, the operation direction conversion software 150 will convert the operation of the touch panel 130 direction, so that the operating direction of the touchpad 130 is switched along 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 (90 degrees to the right, 90 degrees to the left, or 180 degrees), the operation direction conversion software 150 converts the touch screen according to the conversion angle of the display direction. The operation direction of the control panel 130 is such that the converted operation direction corresponds to the new display direction. The steering of the operating direction of the touch panel 130 makes the touch coordinates (X, Y) can be redefined, and corresponds to the display coordinates (X', Y'), so the horizontal axis X of the touch coordinates is again parallel to The horizontal axis X of the display coordinates of the display screen 111 allows the user to use the touchpad 130 intuitively. the

Referring to FIG. 3 and FIG. 4 , the embodiment of the present invention further provides a setting button 160 electrically connected to the system circuit 120 directly, or indirectly electrically connected to the system circuit 120 through the embedded controller 140 . The setting button 160 can be a single independently set button, or a hot key (HotKey) 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, so that the circuit system 120 uses the built-in function of the operating system (such as Microsoft Windows 7) or the driver of the display chip 123 The display direction of the display screen 111 is switched. According to the setting of the operating system or the driver program, the turn signal sent by the setting button 160 every time it is pressed can be defined as a specific rotation direction and rotation angle. For example, every time the setting button 160 is pressed, the display screen will The display direction of 111 is changed to 90 degrees to the right or 90 degrees to the left according to the existing display direction, so that the user can choose the angle to be converted conveniently. The user can press the setting button 160 once, twice or three times according to the desired rotation angle, which is 90 degrees right (or left) rotation, 180 degrees, 270 degrees. After receiving the turn signal of the setting button 160 , the circuit system 120 not only switches the display direction of the display screen 111 , but also sends a system event, so that the operation direction switching software 150 switches the operation direction of the touchpad 130 . the

In addition to using the setting button 160, a program interface menu can also be set in the driver program 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 display direction. Each time the setting button 160 is pressed, the display direction of the display screen 111 can only be rotated towards a specific direction and angle (such as turning left/right 90 degrees), and the program interface menu can list multiple conversion options, each conversion option All have a rotation direction and a rotation angle, such as turning right 90 degrees, turning left 90 degrees, turning 180 degrees, turning right 270 degrees, and turning left 270 degrees. After the user selects one of the conversion options, the operating system sends the steering signal (including the rotation direction and rotation angle) to the circuit system 120 according to the conversion options, so that the circuit system 120 converts the display direction of the display screen 111, And emit this system event. the

Referring to “FIG. 5”, “FIG. 6”, “FIG. 7” and “FIG. 8”, no matter how the display screen 111 changes its display direction, the operation direction conversion software 150 changes the operation direction of the touch panel 130 accordingly. Make the horizontal axis X of the touch coordinates in (X, Y) parallel to the horizontal axis X′ of the display coordinates again. At this time, the operation direction corresponding to the touch track generated by the touch panel 130 can correspond to the setting direction of the display screen 111, so that after the user changes the setting direction of the display screen 110 and the touch panel 130 at the same time, the The touch panel 130 can be intuitively operated. the

In addition to generating track signals, the touch panel of a general electronic device may also provide the function of pressing a button or scrolling a file. The touch panel 130 of the present invention also has the aforementioned function of pressing a button or scrolling a file, as shown in FIG. 9A ” and “Figure 9B”. The touch panel 130 of the present invention not only generates a track signal to be converted into an operation direction, but also has additional functions such as key mode or scroll mode. These additional functions will also be changed by the operation direction conversion software 150 as the operation direction of the touchpad 130 is changed, so as to change its defined blocks or corresponding outputs. the

As shown in “ FIG. 9A ” and “ FIG. 9B ”, a scrolling 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 is parallel to one of two orthogonal axes whose touch coordinates are (X, Y). Generally speaking, the scrolling area 132 is touched to generate a scrolling direction, scrolling the display area of the document file up and down, so the scrolling area 132 is usually arranged parallel to the vertical axis Y of the touch coordinates, and is located on the touch panel. The right side of 130 (it can also be changed to the left side according to the dominant hand). After the operation direction of the touchpad 130 and the display direction of the display screen 111 are switched, the operation direction conversion software 150 will also dynamically change the definition position of the scrolling area 132, so that the scrolling area 132 is located on the touch panel 130 adjacent to the right side area, and change the scrolling direction on the scrolling area 132 at the same time, so that the scrolling direction corresponds to the display direction. the

In addition, through the function setting of the embedded controller 140 or the system circuit 120, the touch panel 130 can have a button mode. Touch the surface of the touchpad 130 twice, and the central processing unit 121 of the system circuit 120 can regard this quick touch as the function of the left mouse button, so that the touchpad 130 can perform the function of the button 131 . Since the button mode is only judged by whether the surface of the touchpad 130 is quickly placed twice, it has nothing to do with the direction or coordinate changes, so when the operating direction of the touchpad 130 and the display direction of the display screen 111 are switched, the user The button mode can still be used according to the original operation method. the

The conversion of the display direction of the display screen 111 can be manually switched by the user or automatically switched through induction. In manual switching, the user can send a turn signal to the system circuit 120 through the program interface menu presented on the display screen 111 or the operation of the setting button 160 to drive the system circuit 120 to switch the display direction of the display screen 111 . The system circuit 120 then sends a system event, so that the operating direction conversion software 150 converts the operating direction of the touchpad 130 so that the operating direction of the touchpad 130 corresponds to the new display direction. the

Referring to "Fig. 10", a touch electronic device 100 that can change the direction of operation disclosed in the second embodiment of the present invention includes a display screen 110, a system circuit 120, a touch panel 130, an embedded A controller 140 and an operation direction switching software 150 . the

The display screen 110, the system circuit 120, the touch panel 130, the embedded controller 140 and the operating direction conversion software 150 of the second embodiment are roughly the same as those of the first embodiment, the difference is that in the second embodiment, one direction is used to sense The device 170 replaces the setting button or the interface setting menu for automatic switching. The direction sensor 170 such as a gravity sensor (G-sensor) is used to detect the setting direction of the display screen 110 . Taking the gravity sensor as an example, the gravity sensor can detect the direction of gravity, so as to obtain a direction detection result, which can be used by the operating system to determine the current orientation of the display screen 110 and determine the conversion angle required for the display screen of the display screen 111. to issue a turn signal. the

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

After the operating direction switching software 150 receives the system event, it changes the direction according to the display screen

Switch the operating direction of the touchpad 130 . At this time, the operating direction of the touchpad 130 can match the display direction of the display screen 111 . the

The present invention uses the operating direction switching software 150 to continuously monitor whether the system circuit 120 sends a system event after switching the display direction of the display screen 111 to switch the operating direction of the touch panel so that the operating direction corresponds to the display direction. This enables the user to intuitively operate the touchpad 130 after the display direction is changed. the
