有关本发明的前述及其他技术内容、特点与功效，在以下配合参考附图的一个较佳实施例的详细说明中，将可清楚地呈现。The aforementioned and other technical content, features and effects of the present invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the accompanying drawings.

参阅图1，是本发明具备双显示器的便携式电子装置的一较佳实施例，在本实施例中该便携式电子装置是以一笔记本型计算机100为例。Referring to FIG. 1 , it is a preferred embodiment of a portable electronic device with dual displays according to the present invention. In this embodiment, the portable electronic device is anotebook computer 100 as an example.

笔记本型计算机100具有一主机本体1和一枢设在主机本体1一侧的显示屏本体2。Thenotebook computer 100 has a host body 1 and adisplay screen body 2 pivotally arranged on one side of the host body 1 .

主机本体1包含一主壳体11，一设于主壳体11内的主机(图未示)，一设于主壳体11的上表面并与主机电连接的键盘12，一设于主壳体11上表面并与主机电连接的触控显示器13，以及一设于键盘12下方的触控板14。The host body 1 includes amain housing 11, a host (not shown) located in themain housing 11, akeyboard 12 located on the upper surface of themain housing 11 and electrically connected to the host, and akeyboard 12 located in the main housing. The upper surface of thebody 11 is atouch display 13 electrically connected to the host computer, and atouch panel 14 is arranged under thekeyboard 12 .

显示屏本体2藉由一二维枢转件21枢接于主壳体11的一侧，显示屏本体2朝向主机本体1的一面设有一与主机电连接的平面显示器22，藉由二维枢转件21，显示屏本体2可朝接近主机本体1方向枢转而盖合于主机本体1上，或朝远离主机本体1方向枢转而处于一掀开位置，且显示屏本体2位于掀开位置时，如图2所示，显示屏本体2可藉由二维枢转件21相对主机本体1向左(或向右)枢转，则显示屏本体2相对主机本体1向左(或向右)枢转90度可使平面显示器22面向主机本体的左侧(或右侧)，而显示屏本体2相对主机本体1向后旋转180度则使平面显示器22背对主机本体1。Thedisplay screen body 2 is pivotally connected to one side of themain casing 11 by a two-dimensional pivoting member 21, and the side of thedisplay screen body 2 facing the host body 1 is provided with aflat panel display 22 electrically connected to the host, and the two-dimensionalpivot Rotating member 21, thedisplay screen body 2 can pivot toward the direction of the host body 1 and cover it on the host body 1, or pivot away from the host body 1 to be in an opened position, and thedisplay screen body 2 is in the opened position. position, as shown in Figure 2, thedisplay screen body 2 can pivot to the left (or right) relative to the host body 1 by the two-dimensional pivoting member 21, then thedisplay screen body 2 pivots to the left (or to the right) relative to the host body 1 Right) pivoting 90 degrees can make the plane display 22 face the left side (or right side) of the host body, while thedisplay screen body 2 rotates 180 degrees backward relative to the host body 1 so that the plane display 22 faces away from the host body 1.

如图3所示，笔记本型计算机的主机主要包含一主机板3以及相关周边连接接口(图未示)，在本实施例中，主机板3主要包含一中央处理单元31、一视频存储器(VRAM)32、一视频处理单元(VGA)33、一信号控制器34及一控制单元。As shown in Figure 3, the main frame of the notebook computer mainly includes amotherboard 3 and related peripheral connection interfaces (not shown), in this embodiment, themotherboard 3 mainly includes acentral processing unit 31, a video memory (VRAM ) 32, a video processing unit (VGA) 33, asignal controller 34 and a control unit.

其中控制单元包含一南桥控制器35和一北桥控制器36，且南桥控制器35电连接北桥控制器36和信号控制器34。The control unit includes asouth bridge controller 35 and anorth bridge controller 36 , and thesouth bridge controller 35 is electrically connected to thenorth bridge controller 36 and thesignal controller 34 .

中央处理单元31在本实施例中主要是提供一影像的视频数据给视频存储器32。视频处理单元33读取视频存储器32中的视频数据并同时输出至触控显示器13及平面显示器22显示。In this embodiment, thecentral processing unit 31 mainly provides video data of an image to thevideo memory 32 . Thevideo processing unit 33 reads the video data in thevideo memory 32 and simultaneously outputs the video data to thetouch display 13 and theflat panel display 22 for display.

由于视频处理单元33读取同一视频存储器32中的视频数据分别送给触控显示器13和平面显示器22，所以，触控显示器13和平面显示器22会同时显示相同的影像内容。Since thevideo processing unit 33 reads the video data in thesame video memory 32 and sends them to thetouch display 13 and theflat panel display 22 respectively, thetouch display 13 and theflat panel display 22 will simultaneously display the same image content.

所以当使用者和另一观看者同时要看笔记本型计算机的显示画面时，可以把显示屏本体转至让平面显示器22面向观看者的位置，让观看者可以清楚地看到显示画面，而使用者也可通过触控显示器清楚看到相同的显示画面，让使用者可以方便地向观看者进行简报或解说。Therefore, when the user and another viewer want to see the display screen of the notebook computer at the same time, the display screen body can be forwarded to the position where the flat panel display 22 faces the viewer, so that the viewer can clearly see the display screen, and use The viewer can also clearly see the same display screen through the touch display, so that the user can conveniently give briefings or explanations to the viewers.

信号控制器34在本实施例中是一键盘控制器，其除了将来自键盘的按键信号通过南桥控制器和北桥控制器送给中央处理单元处理外，并对应键盘上预设的某些热键(可能是单一按键或多个按键的组合)产生对应的控制，例如显示器画面亮度调整或声音控制等外，在本实施例中信号控制器34还与触控显示器13电连接，其可接收来自触控显示器13的一触控信号，并通过南桥控制器35和北桥控制器36将该触控信号送至中央处理单元31，使中央处理单元31根据该触控信号产生对应的影像视频数据并送至视频存储器32。Signal controller 34 is a keyboard controller in the present embodiment, and it is except that the key signal from keyboard is sent to central processing unit by south bridge controller and north bridge controller to process, and some thermal presets on the corresponding keyboard key (may be a single key or a combination of multiple keys) to generate corresponding controls, such as display screen brightness adjustment or sound control, etc. In this embodiment, thesignal controller 34 is also electrically connected to thetouch display 13, which can receive A touch signal from thetouch display 13, and send the touch signal to thecentral processing unit 31 through thesouth bridge controller 35 and thenorth bridge controller 36, so that thecentral processing unit 31 generates a corresponding image and video according to the touch signal The data is sent to thevideo memory 32.

因此，由上述说明可知，中央处理单元31对应使用者在触控显示器13上进行触控操作所产生的影像会被同时送至触控显示器13及平面显示器22显示。Therefore, it can be seen from the above description that the image generated by thecentral processing unit 31 corresponding to the user's touch operation on thetouch display 13 will be simultaneously sent to thetouch display 13 and theflat panel display 22 for display.

所以，当使用者通过笔记本型计算机1的显示内容向另一观看者做简报或解说时，使用者可直接在触控显示器13上进行触控操作，且触控方式可通过键盘上的一预设的热键切换至一般输入模式或手写输入模式。当在一般输入模式时，使用者可在触控显示器13上直接点选显示画面上的选项或执行画面中显示的某些功能，或者以触控手势输入控制指令。而当在手写输入模式时，使用者可在触控显示器13上直接进行手写输入。中央处理单元31则将根据使用者在触控显示器13上的触控操作所产生的触控信号对应产生的相应的影像暂存在视频存储器中，由视频存储器读取并同时输出至触控显示器13和平面显示器22上。Therefore, when the user makes a briefing or explanation to another viewer through the display content of the notebook computer 1, the user can directly perform a touch operation on thetouch display 13, and the touch method can be controlled by a preset button on the keyboard. You can switch to the general input mode or handwriting input mode by using the set hotkey. When in the general input mode, the user can directly click on the options on the display screen on thetouch display 13 or execute certain functions displayed on the screen, or input control commands with touch gestures. While in the handwriting input mode, the user can directly perform handwriting input on thetouch display 13 . Thecentral processing unit 31 temporarily stores the corresponding image corresponding to the touch signal generated by the user's touch operation on thetouch display 13 in the video memory, reads it from the video memory and outputs it to thetouch display 13 at the same time. andflat panel display 22.

由于上述触控显示器对于一般输入或手写输入的触控判断技术为公知，且非本案重点，在此不加详述。Since the above-mentioned touch detection technology for general input or handwriting input is well known, and is not the focus of this case, it will not be described in detail here.

此外，为了让使用者在使用键盘12时，不致误触触控显示器13，可在键盘12上设置一开/关触控显示器的触控功能的热键，在触控显示器13的触控功能开启状态下，热键被按压会发出一第一热键信号给信号控制器34，使根据第一热键信号暂时关闭触控显示器13的触控功能(或关闭触控显示器13的电源)；反之，在触控显示器13的触控功能关闭状态下，热键被按压时会发出一第二热键信号给信号控制器34，使根据第二热键信号开启触控显示器的触控功能(或重新供电给触控显示器13)。In addition, in order to prevent the user from touching thetouch display 13 by mistake when using thekeyboard 12, a hot key for turning on/off the touch function of the touch display can be set on thekeyboard 12, and the touch function of thetouch display 13 In the open state, when the hotkey is pressed, a first hotkey signal will be sent to thesignal controller 34, so that the touch function of thetouch display 13 is temporarily closed (or the power supply of thetouch display 13 is turned off) according to the first hotkey signal; Conversely, when the touch function of thetouch display 13 is off, when the hot key is pressed, a second hot key signal will be sent to thesignal controller 34, so that the touch function of the touch display can be turned on according to the second hot key signal ( Or re-power the touch display 13).

另外，除了上述做法外，信号控制器34亦可将收到的第一热键信号或第二热键信号通过南桥控制器35和北桥控制器36送给中央处理单元31，中央处理单元31对应第一热键信号或第二热键信号产生一禁用信号或使能信号送给信号控制器34，使信号控制器34根据禁用信号或使能信号来关闭或开启触控显示器的触控功能。In addition, in addition to the above-mentioned approach, thesignal controller 34 can also send the received first hotkey signal or the second hotkey signal to thecentral processing unit 31 through thesouth bridge controller 35 and thenorth bridge controller 36, and thecentral processing unit 31 Corresponding to the first hotkey signal or the second hotkey signal, a disabling signal or an enabling signal is generated and sent to thesignal controller 34, so that thesignal controller 34 turns off or turns on the touch function of the touch display according to the disabling signal or the enabling signal .

再者，本实施例的平面显示器22也可以是一触控显示器，但是当平面显示器22被枢转至面对另一观看者时，为了避免观看者自行触控平面显示器22，笔记本型计算机100上还可以设置一用以检测显示屏本体2是否相对主机本体1枢转至例如大于60度的枢转检测组件37。Moreover, theflat display 22 of this embodiment can also be a touch display, but when theflat display 22 is pivoted to face another viewer, in order to prevent the viewer from touching theflat display 22 by himself, the notebook computer 100 Apivot detection component 37 for detecting whether thedisplay screen body 2 is pivoted to, for example, greater than 60 degrees relative to the host body 1 can also be provided on the screen.

枢转检测组件37邻近二维枢转件设置并电连接信号控制器34，当显示屏本体2被相对主机本体1枢转至大于60度时，枢转检测组件会发出一第一检测信号给信号控制器34，信号控制器34根据该第一检测信号产生一触控禁用信号通过南桥控制器35和北桥控制器36送给中央处理单元31，中央处理单元31根据此触控禁用信号将平面显示器22的触控电路220的触控输入功能暂时禁用，直到显示屏本体2再枢转至相对主机本体小于60度时，枢转检测组件37会再发出一第二检测信号给信号控制器34，信号控制器34根据该第二检测信号产生一触控使能信号通过南桥控制器35和北桥控制器36送给中央处理单元31，中央处理单元31根据此触控使能信号令平面显示器22的触控电路220重新接受触控输入。The pivotingdetection component 37 is arranged adjacent to the two-dimensional pivoting member and electrically connected to thesignal controller 34. When thedisplay screen body 2 is pivoted to more than 60 degrees relative to the main body 1, the pivoting detection component will send a first detection signal to the Thesignal controller 34, thesignal controller 34 generates a touch disable signal according to the first detection signal and sends it to thecentral processing unit 31 through thesouth bridge controller 35 and thenorth bridge controller 36, and thecentral processing unit 31 disables the touch according to the signal The touch input function of thetouch circuit 220 of theflat panel display 22 is temporarily disabled until thedisplay screen body 2 is pivoted to less than 60 degrees relative to the host body, and thepivot detection component 37 will send a second detection signal to thesignal controller 34. Thesignal controller 34 generates a touch enable signal according to the second detection signal and sends it to thecentral processing unit 31 through thesouth bridge controller 35 and thenorth bridge controller 36. Thecentral processing unit 31 makes the plane touch according to the touch enable signal. Thetouch circuit 220 of thedisplay 22 accepts touch input again.

当然，上述平面显示器22的触控功能启闭与否，也可通过在键盘上设定上述热键的方式来达成。Of course, whether the touch function of the flat-panel display 22 is turned on or off can also be achieved by setting the hotkeys on the keyboard.

再者，值得一提的是，本实施例的触控显示器13可应用公知的触控检测技术，根据在触控显示器13上进行的触控操作，将平面显示器22显示的画面对应进行适当的放大或缩小。Furthermore, it is worth mentioning that thetouch display 13 of this embodiment can apply known touch detection technology, and according to the touch operation performed on thetouch display 13, the screen displayed on the flat-panel display 22 can be properly matched. Zoom in or out.

例如，当平面显示器22及触控显示器13同时显示同一网页内容时，使用者可通过操控触控显示器13，例如改变触控的手势来控制平面显示器22显示的网页放大或缩小。亦即使用者的触控手势所对应产生的触控信号会经由信号控制器34、南桥控制器35和北桥控制器36送给中央处理单元31，中央处理单元31判断此一触控信号对应一放大画面指令或缩小画面指令时，则通过驱动硬件或软件来实现网页放大或缩小的动作。举例说明可采用的做法如下：For example, when the flat-panel display 22 and the touch-sensitive display 13 simultaneously display the same webpage content, the user can control the webpage displayed on the flat-panel display 22 to zoom in or out by manipulating the touch-sensitive display 13 , such as changing the touch gesture. That is, the touch signal generated corresponding to the user's touch gesture will be sent to thecentral processing unit 31 through thesignal controller 34, thesouth bridge controller 35 and thenorth bridge controller 36, and thecentral processing unit 31 judges that the touch signal corresponds to When there is an instruction to zoom in or zoom out the screen, the action of zooming in or zooming out the webpage is realized by driving hardware or software. Examples of possible approaches are as follows:

一、以视频处理单元33直接缩放画面内容：1. Use thevideo processing unit 33 to directly scale the picture content:

在正常显示情况下，视频处理单元33会直接从视频存储器32读取视频数据并同时分别输出至平面显示器22和触控显示器13(假若两者的分辨率皆为1024×768)，而当中央处理单元31收到一放大画面指令时，中央处理单元31通知视频处理单元33进行画面放大处理，此时，如图4所示，视频处理单元33中的一图形处理单元(GPU，图未示)抓取视频存储器32(其中存有一个全屏幕画面，即1024×768分辨率的视频数据)中对应于画面中间区域的局部影像数据40(例如800×600分辨率的视频数据)，且将之放大(scalingup)至可填满整个平面显示器22的1024×768分辨率的视频数据41并输出至平面显示器22，如此，平面显示器22即显示原画面中间区域的放大影像。Under normal display conditions, thevideo processing unit 33 will directly read the video data from thevideo memory 32 and simultaneously output the video data to theflat panel display 22 and the touch display 13 (if the resolutions of both are 1024×768), and when the central When theprocessing unit 31 received an enlarged picture instruction, thecentral processing unit 31 notified thevideo processing unit 33 to carry out picture enlargement processing. At this moment, as shown in FIG. 4 , a graphics processing unit (GPU, not shown in the figure) ) captures the local image data 40 (such as video data of 800 * 600 resolution) corresponding to the middle area of the picture in the video memory 32 (wherein a full-screen picture is stored, i.e. video data of 1024 * 768 resolution), and will Thevideo data 41 with a resolution of 1024×768 that can be scaled up to fill the entire flat-panel display 22 is output to the flat-panel display 22. In this way, the flat-panel display 22 promptly displays the enlarged image of the middle area of the original picture.

同理，以硬件来进行画面缩小时，视频处理单元33中的图形处理单元(GPU)只间隔地读取视频存储器32中的部分视频数据并输出至平面显示器22。例如图5所示，视频存储器32中存一个全屏幕画面，即1024×768分辨率的视频数据，若要将原画面缩小至只占屏幕中间部分的例如800×600空间，则视频处理单元33中的图形处理单元(GPU)只从视频存储器32中间隔地读取800×600分辨率的视频数据50并输出至平面显示器22的屏幕中间区域，而其他区域则显示全白或全黑画面，如此即可将平面显示器22原先显示的1024×768大小的全屏幕画面缩小至800×600的缩小画面。Similarly, when the image is reduced by hardware, the graphics processing unit (GPU) in thevideo processing unit 33 only reads part of the video data in thevideo memory 32 at intervals and outputs it to theflat panel display 22 . For example as shown in Figure 5, a full-screen picture is stored in thevideo memory 32, i.e. the video data of 1024*768 resolution, if the original picture is to be reduced to such as 800*600 space that only accounts for the middle part of the screen, then thevideo processing unit 33 The graphic processing unit (GPU) in only reads thevideo data 50 of 800 * 600 resolution at intervals from thevideo memory 32 and outputs to the middle area of the screen of theflat panel display 22, while other areas then display full white or full black pictures, In this way, the original full-screen image of 1024×768 displayed on the flat-panel display 22 can be reduced to a reduced image of 800×600.

二、以中央处理单元31配合软件来缩放画面内容：2. Use thecentral processing unit 31 to cooperate with software to zoom the picture content:

前提是，如图6所示，视频存储器32中需预先配置两个可暂存一个全屏幕画面的存储空间，例如暂存1024×768分辨率视频数据的第一存储区321及第二存储区322，第一存储区321主要暂存全屏幕画面的视频数据(即1024×768分辨率的视频数据)。第二存储区322供暂存经过缩放的视频数据。The premise is that, as shown in Figure 6, two storage spaces that can temporarily store a full-screen picture need to be pre-configured in thevideo memory 32, such as thefirst storage area 321 and the second storage area for temporarily storing 1024*768 resolution video data. 322. Thefirst storage area 321 mainly temporarily stores video data of a full-screen image (that is, video data with a resolution of 1024×768). Thesecond storage area 322 is used for temporarily storing the scaled video data.

因此，当平面显示器22在正常显示状态时，视频处理单元33会从第一存储区321读取视频数据并同时分别送至平面显示器22及触控显示器13。而当中央处理单元31收到一放大画面指令时，中央处理单元31通过驱动器(driver)读取第一存储区321中对应于画面中间区域的局部视频数据60，例如800×600分辨率，并放大成1024×768分辨率的视频数据61后存入第二存储区322，中央处理单元31则控制视频处理单元33读取第一存储区321的视频数据输出至触控显示器13，但读取第二存储区322的视频数据输出至平面显示器22，如此，则可使平面显示器22显示原画面中间区域的放大影像。Therefore, when the flat-panel display 22 is in a normal display state, thevideo processing unit 33 reads video data from thefirst storage area 321 and simultaneously sends them to the flat-panel display 22 and thetouch display 13 respectively. And when thecentral processing unit 31 received an instruction to enlarge the picture, thecentral processing unit 31 read thepartial video data 60 corresponding to the middle area of the picture in thefirst storage area 321 through the driver (driver), such as 800 * 600 resolution, and Thevideo data 61 enlarged to 1024×768 resolution is stored in thesecond storage area 322, and thecentral processing unit 31 controls thevideo processing unit 33 to read the video data in thefirst storage area 321 and output it to thetouch display 13. The video data in thesecond storage area 322 is output to the flat-panel display 22, so that the flat-panel display 22 can display the enlarged image of the middle area of the original frame.

同理，以软件驱动器来进行画面缩小时，如图7所示，中央处理单元31通过驱动器间隔地读取第一存储区321中的部分数据，例如从1024×768分辨率的视频数据中读取800×600分辨率的视频数据70并填入第二存储区322中对应于屏幕画面中间区域的存储位置，第二存储区322中的其他存储位置则填入0。如此当视频处理单元33读取第二存储区322中的视频数据输出至平面显示器22时，平面显示器22的屏幕中间即显示原画面缩小至800×600分辨率的缩小画面。Similarly, when using a software driver to reduce the image size, as shown in Figure 7, thecentral processing unit 31 reads part of the data in thefirst storage area 321 through the driver at intervals, for example, from video data with a resolution of 1024*768. Thevideo data 70 with a resolution of 800×600 is taken and filled into the storage location corresponding to the middle area of the screen image in thesecond storage area 322 , and 0 is filled in other storage locations in thesecond storage area 322 . In this way, when thevideo processing unit 33 reads the video data in thesecond storage area 322 and outputs it to the flat-panel display 22 , the center of the screen of the flat-panel display 22 displays a reduced image of the original image reduced to a resolution of 800×600.

由上述说明可知，由于触控显示器13的视频数据来源一直都是同一个存储区(视频存储器32或第一存储区321)，因此，当平面显示器22显示的画面被放大或缩小时，触控显示器13的显示画面不会随之被放大或缩小而仍维持原来的全屏幕画面，可方便使用者进行编辑操作。As can be seen from the above description, since the video data source of thetouch display 13 is always the same storage area (video memory 32 or first storage area 321), therefore, when the picture displayed on the flat-panel display 22 is enlarged or reduced, the touch The display image of thedisplay 13 will not be enlarged or reduced accordingly, but still maintains the original full-screen image, which is convenient for users to perform editing operations.

当然，上述放大画面或缩小画面的指令也可以由键盘上预设的两个热键来产生，并通过信号控制器34、南桥控制器和北桥控制器36送给中央处理单元31。Certainly, the above-mentioned command to zoom in or zoom out can also be generated by two preset hotkeys on the keyboard, and sent to thecentral processing unit 31 through thesignal controller 34 , the south bridge controller and thenorth bridge controller 36 .

综上所述，本实施例藉由在主机本体1的键盘12旁边设置一触控显示器13，并使显示屏本体2可以相对主机本体1枢转，使得当显示屏本体2枢转至使显示屏本体2上的平面显示器13面向另一观看者时，使用者仍可通过主机本体1上的触控显示器13看到和平面显示器13相同的显示画面，并可直接在触控显示器13上进行触控操作，增加笔记本型计算机使用上及展示显示内容上的方便性。此外，通过触控显示器13或键盘12上的热键控制平面显示器22显示画面的缩放，使笔记本型计算机的显示应用更具灵活性。To sum up, in this embodiment, atouch display 13 is arranged next to thekeyboard 12 of the main body 1, and thedisplay screen body 2 can pivot relative to the main body 1, so that when thedisplay screen body 2 pivots to make the display When theflat display 13 on thescreen body 2 faces another viewer, the user can still see the same display screen as theflat display 13 through thetouch display 13 on the main body 1, and can directly perform The touch operation increases the convenience of using the notebook computer and displaying the displayed content. In addition, the scaling of the display screen of the flat-panel display 22 is controlled by the hot keys on thetouch display 13 or thekeyboard 12, so that the display application of the notebook computer is more flexible.

惟以上所述的内容，仅为本发明的较佳实施例而已，应当不能以此限定本发明实施的范围，即凡是依本发明权利要求书范围及发明说明内容所作的简单的等同变化与修饰，皆仍属本发明专利涵盖的范围内。However, the above-mentioned content is only a preferred embodiment of the present invention, and should not limit the implementation scope of the present invention, that is, any simple equivalent changes and modifications made according to the scope of the claims of the present invention and the contents of the description of the invention , all still belong to the scope covered by the patent of the present invention.
