However, the keyboard input device disclosed in the TW537490 patent does not have a generally recognized touch function 'that is, it cannot be controlled anywhere on the touch panel as the touch device is generally' and its design cannot be changed. Furthermore, electronic devices using the same often require a touch device having a pointer pointing function to perform a mouse input operation, thereby increasing the size and cost of the electronic device. Another prior art, such as the touch device disclosed in US Pat. No. 6,850,220, is determined by the software program to determine that a mouse pointer window and/or a tool window are displayed on the display device, thereby executing the mouse. Input operations and/or keyboard input operations. However, this prior art requires 201020877 to design an extremely complex software program to achieve its functions.

Mouse control signal. The keyboard controller is electrically coupled to the touch controller to receive the touch signal output from the touch controller when the touch signal is a keyboard touch signal, and convert the received touch signal into a corresponding one of the keyboard control signals. . The central processor is electrically coupled to the mouse controller and the keyboard controller to receive the mouse control signal and the keyboard control signal respectively, and generate corresponding control signals according to the mouse control signal or the keyboard control signal. Another embodiment of the present invention provides an electronic device using a touch device, which includes a touch device and a processing device. The touch device includes a touch panel and a light guide plate. The touch panel has a first surface that generates a touch signal when the object approaches the first surface from above the touch panel.

Therefore, the touch device of the embodiment of the present invention has a keyboard input function, and the electronic device of the embodiment of the present invention does not require an additional keyboard input device, which reduces the cost and reduces the volume thereof. In addition, the touch device of the embodiment of the present invention and the 201020877 electronic device have a night vision function by a light source optically combined with the light guide plate, which is convenient for the user to use at night. The above and other objects, features, and advantages of the present invention will become more apparent and understood. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention. The square (four) words mentioned in the following embodiments, for example, up, down, left, right front or back ❹, etc. are merely directions referring to the additional drawings. Therefore, the directional terminology used is not intended to limit the invention. FIG. 1 is a schematic diagram of a touch device according to an embodiment of the invention. Referring to FIG. 1 , the touch device 10 includes a touch panel 110 , a light guide plate 12 , and a processing device 150 . The touch panel no has a first surface I. The light guide plate is disposed on the first surface 111 and is located on the touch panel 10 . Above the panel 110, the light guide plate 12 is provided with at least one button pattern (not shown). The processing device 150 is electrically coupled to the touch panel 110 to process signals generated by the touch panel. Under normal conditions, the user will face the first side U1 during operation, so that the user's finger or the object held by the user will be operated from the top of the touch panel 11A to the first side m. Since the light guide plate 12 is disposed on the first surface m and above the touch panel 110, the user will not be able to directly contact the first side 111. In this case, in order to enable the touch panel 110 to operate correctly, a touch panel capable of generating a signal without requiring the user to directly touch the first surface 1U', such as a capacitive touch panel or a pressure type, is selected. Touch panel. For example, when the capacitive touch panel is used as the touch panel 110 in this embodiment, the user can change the touch panel 110 due to capacitance by pressing the light guide plate 120 or even merely approaching the light guide plate 120. And generate a touch 6 201020877 control signal. In another example, the touch panel 110 of the present embodiment is a pressure touch panel. The pressure applied by the user on the light guide plate 120 can also cause the touch panel 110 to generate a corresponding touch signal. As a result, the touch panel 110 can correctly generate the corresponding touch signal when the object is not directly in contact with the first surface 111. . The light guide plate 120 includes a first surface 121 and a second surface 122. The first surface 121 is adjacent to the touch panel 110 , and the second surface 122 is opposite to the first surface 121 and away from the touch panel 110 . The aforementioned key patterns may be formed on the first surface 121 of the light guide plate 120, respectively. Of course, these button patterns can also be formed on the second surface 122 of the light guide plate 120, respectively. As shown in FIG. 1 , the processing device 150 is electrically coupled to the touch panel 110 to receive the touch signals generated from the touch panel 110 , and detects corresponding contact positions and corresponding controls according to the touch signals. Signal. The processing device 150 and the touch panel 110 can be electrically coupled by a flexible circuit board. Additionally, touch device 10 can further include control switch 140 and/or light source 130. The light source 130 is disposed adjacent to the light guide plate 120 to be optically coupled to the light guide plate 120. The control switch 140 can be disposed on the touch panel no. The control switch 140 is configured to control the touch signal generated by the touch panel 110 to include one of a keyboard touch signal and a mouse touch signal. Specifically, when the control switch 140 is in the first state, the touch signal generated by the touch panel 110 is a keyboard touch signal, that is, when the user presses the light guide plate 120, the touch panel 11 detects the capacitance or pressure change. The corresponding touch signal generated is a keyboard touch signal. At this time, the contact position detected by the touch panel 110 will be used to correspond to the position of the button pattern disposed on the light guide plate 120, thereby implementing the keyboard input function. When the control switch 140 is in the second state, the touch panel 7 generated by the touch panel no is the mouse touch, the signal, that is, when the user presses the light guide plate 120B, the touch panel 110 senses the electric valley or the pressure change. The corresponding touch signal generated by the amount is a mouse touch signal for performing a pointer pointing operation to realize a mouse input function. For example, control switch 140 can be a button. When the button is pressed, the switch 140 is controlled in the first state; when the button is restored, the control switch 140 is in the second state. Of course, the control switch 14A can also be a soft body switch. For example, the software switch may correspond to the first area and the second area of the light guide plate 12, and when the user presses the first area of the light guide plate 120, the control switch 14 is in the first state, when the user presses the light guide plate 120. In the second region, the control switch 14 is at 0 in the second state. The light source 130 is optically coupled to the light guide plate 120. When the user uses the touch control device 10 at night, the light emitted by the light source 130 enters the light guide plate 120 to illuminate the button patterns on the light guide plate 120, so that the touch device 1 has a night vision function, which is convenient for the user to use. Or 'in another design manner, when the control switch 140 is in the first state (ie, the keyboard input mode), the light source π 可以 can be turned on to facilitate the user to confirm the position of the button pattern; and the control switch 14 〇 is in the second state. In the state (ie, the mouse control mode), the light source 13 is turned off to save power. FIG. 2 is a schematic structural view of a touch panel according to an embodiment of the invention. Referring to FIG. 2, in the embodiment, the touch panel ι 10 includes a plurality of touch panels 114, 116, and 118. The touch panels 114, 116, and 118 respectively correspond to different areas of the light guide plate 120 of the keyboard pattern. For example, the touch panel 114 corresponds to a numeric key and a letter key area of the keyboard pattern, and the touch panel 116 corresponds to the left of the keyboard pattern. The function button area corresponds to the right function button area of the keyboard pattern. Therefore, when the user uses the touch device 10 to implement the keyboard input function, the user can simultaneously press two or two of the light guide plates 12 The above key patterns (such as the left Fn button + 2 number keys), thereby achieving multi-touch and simultaneous multi-input 8 201020877 operation. Si is a circuit block diagram of a processing device according to the present invention. As shown in FIG. 3, the processing device 15G includes a touch controller 152, a mouse controller (9), a keyboard controller 156, and a central processing unit 158.
