The touchpad provides a simple, lightweight, and inexpensive pointing device, such as a mouse that is applied to the touchpad of a notebook. The fifth figure provides a schematic diagram of the operation of the capacitive touch panel, which includes an insulating plate 48, a ground plate 36, a gamma axis trace 38, and a layer of χ axis traces 4〇, all of which are connected to the control circuit 46. There is an equivalent capacitance 42 between the gamma axis trace 38 and the ground plane 36, and an equivalent capacitance 44 exists between the X-axis trace 4 and the ground plane 36. When the finger or conductor touches the insulating plate 48, the latching circuit 46 can ride the finger or conductor contact by the change in capacitance and further perform appropriate processing. Known touch panels are resistive, electromagnetic, and capacitive, and U! 7 % valley touch screens have been used in public telephones or navigation systems such as Internet access, but without graphical input and handwriting input. Resistive touch; the screen has been applied to, for example, a personal digital assistant (pDA) or an electronic dictionary. However, the user enters by touching the user's finger. Currently, Tablet PCs or e-books, etc., are equipped with touch panels that integrate handwriting recognition and key input functions, but they are either resistive or electromagnetic. When the touchpad of the resistor is operated, the pressure point needs to be concentrated and the volume (4) is damaged, and the electromagnetic touch panel 5 M297026 control board needs to be input with a battery input pen. In terms of performance and cost, capacitive touch panels clearly outperform resistive and electromagnetic touch panels. The working principle of the capacitive touch panel is to use the user's hand or the contact of the conductor to the touchpad to create a capacitive effect, so that the position of the finger or conductor can be determined by the change of the capacitance value. Therefore, the capacitive j touchpad does not have to rely on an input pen that consumes power as the electromagnetic touchpad does, and the use of the capacitive touchpad does not require the use of a resistive touchpad, and thus has a longer service life. Furthermore, the capacitive touch panel has a simple composition, a small number of 7L parts, and a high product yield, which makes the capacitive touch panel low in mass production. On the other hand, in the current electronic devices, graphics input has become an emerging trend and the demand has become increasingly popular and increased. For example, the communication of mobile phone newsletters has evolved from text transmission to text-combined graphics transmission, thus providing a more compact form. The touchpad, which is small, cheaper, and integrates the input and output functions. [New Content] The purpose of this creation is to propose a capacitive touch panel that integrates graphics input functions. According to the present invention, a capacitive touch panel integrated with a graphic input function can provide various operation modes such as a graphic input, a button, a handwriting input, a mouse, and the like, and the panel of the touch panel is defined with a plurality of regions. There are a plurality of patterns on the upper print corresponding to the provided operation modes, and the patterns include a switch switch for the selected operation mode. In the graphics input mode, the zone ^ M297026 includes - the graphics input area provides graphical input. In the button mode...Hai et al. The pattern contains a button pattern that simulates a keyboard. In handwriting input mode: these areas contain - handwriting recognition area to provide handwriting input. Under the mouse (four), the areas include the cursor motion area and the horizontal and vertical scrolling: force [embodiment] The first figure is a schematic diagram of the present embodiment, and the touch panel 1 includes a training head for a finger or a conductor. Touching the input, the mode switching switch pattern 14 is on the panel 12 for touching to switch the capacitive touch panel into a graphic input, a button, a handwriting input or a mouse mode, and the virtual button areas 16, 18 and 20 is defined on the panel 12, respectively, and a display 22 displays the data entered by the virtual button zones 16, 18 and 20 or the current fall mode. When the user switches the touchpad 10 to the graphic input mode, the virtual key zones 16 and 20 become the graphic input area 24, and cooperate with the virtual button: the input, cancel, style and storage function keys of the area 18, such as As shown in Figure A, a graphical input can be provided. The user can draw a graphic with the finger or conductor in the graphic input area 24, and the graphic will be directly displayed on the display 22 and can be graphically edited and then sent out. The user touches the touch panel 10 to the button mode, the numeric button, the #-key and the *-key pattern of the virtual button area 16, the dialing, canceling, and the upper and lower directions of the virtual button area 18 And the function key pattern of the recovery, redial and retention of the virtual button area 20 is as shown in the first figure b M297026, and can be provided as a keyboard of the telephone. The user can enter the telephone number to be dialed, and the entered telephone number is displayed on the display 22 after being processed by the corresponding software or hardware. Once the user switches the touchpad 10 to the handwriting input mode, the virtual button zones 16 and 20 become the handwriting recognition area 26, and the function keys such as input, cancel, font, and word selection of the virtual button zone 18 are matched. The pattern, as shown in the first figure C, can provide a handwriting input operation. The user can write in the handwriting recognition area 26 with a finger or a conductor, and after processing through a corresponding software or hardware (for example, a handwriting input recognition module), display the result of handwriting input, such as a track or a character, a symbol, and the like. On display 22. There is a significant difference between the handwriting input mode and the graphic input mode. In the handwriting input mode, when the user's input stops for a response time, the handwriting input recognition module in the touchpad actively recognizes the user's input, and in the graphic input mode, It is dependent on the user to issue an instruction to indicate the completion of the graphic input, and the • reaction time can be adjusted according to the user's needs. The user switches the touchpad 1 to the mouse mode, and the virtual button area 16 becomes a cursor (cur.) action area 28, in which the user can control the motion of the cursor, and the virtual button area 18 becomes a vertical scroll. The function area, and the virtual button area 20 becomes a horizontal scroll function area, as shown in the first figure, wherein the vertical and horizontal scroll function areas provided by the virtual button areas 18 and 20 simulate the mouse vertically or horizontally. The function of the scrolling function is similar to, for example, the vertical and horizontal reels in the icecr〇s〇f 士Off ice document processing software. M297026 In addition, a finger recognition area 2 "(4) number can be added, and according to the instruction of touching the cursor action, for example, when the finger recognition module determines that there are two different boards, the simulation clicks the left mouse button.
