Description of the Invention: [Technical Field] [0001] The present invention provides a touch panel structure and an input method thereof, and in particular, a combination of two touch layers Touch panel structure. [Prior Art] [0002] In the current society where information is developed, a large amount of information knowledge can be exchanged, organized and stored through digital data; and electronic devices used to read and access digital data become a modern information society. The most important tool of -. In particular, various portable electronic devices (such as notebook computers and '(4) number of assistants & etc.) are small, lightweight and portable, allowing users to view, view and store various digits anytime, anywhere. The data is the best digital data platform...and the information# is dedicated to the focus of research and development. The round portable electronic device - aspect _ volume (four), - in addition to the humanized input interface, so often use the touch panel as the human interface between the user disk portable electronic device. When the user touches the touch panel, the touch panel can sense the position of the pressure (or the pressure of the pressing pressure), and represent different control commands according to the position of the pressure, thereby controlling the electronic device. Furthermore, due to the advancement of handwriting recognition technology, when the user wants to input data into the portable electronic device, the user can directly write and write the data on the touch panel, and the portable electronic device is based on the touch. The user's writing traces sensed by the control panel can identify the data that the user wants to turn in, and then store the data into the portable electronic device. Handwriting input can not only reduce the space occupied by the portable electronic device, so that the portable electronic device does not need to adopt the volume 096115151 Form No. A0101 Page 3 / Total 14 Page 0993202375-0 1328766 ι_, June 08, 2008 The core replaces the large keyboard; on the other hand, it provides a more friendly interface, making it easier for users to intuitively control the portable electronic device through the touch panel. [0004] However, currently, touch panels used in portable electronic devices include a resistive touch panel and a capacitive touch panel. The resistive touch panel needs to apply pressure on the screen to touch, so when the user operates the touch panel, it is difficult to operate with a finger, and the stylus is required to input; and the capacitive touch panel is an application capacitor. When the sensor is touched, it is usually necessary for the user to perform handwriting input. Since the touch panel of the current portable computer fails to display the handwriting of the positive operation, it is often necessary to perform the handwriting input character. While looking up at the computer display screen to know whether the character is being written correctly, it not only affects the convenience of the user's operation, but also affects the speed of the rounded font. When inputting a stroke with more characters, it is often because It is impossible to grasp the relative position of the input strokes and affect the recognition rate. Therefore, under the trend of requiring a human-machine interface, there is still considerable room for improvement in handwriting input on the touch panel. [0005] Please refer to the first figure, which is a schematic diagram of a resistive touch panel of the prior art. The resistive touch panel 10 includes an ITO glass 12, an ITO film 16 and a plurality of spacers 14 sandwiched therebetween. The conductive glass 12 is parallel to the opposite side edges 121 and 122 of the Y-axis direction in the figure, and has different voltage levels to generate a voltage gradient on the conductive glass 12 perpendicular to the TY axis. The conductive film 16 is parallel to the opposite side edges 161 and 162 of the X-axis direction of the figure, and also has different voltage levels to produce 096115151 on the conductive film 16. Form No. A0101 Page 4 / Total 14 Page 0993202375 -0 On June 8, 099, the replacement page is perpendicular to the voltage gradient in the X-axis direction of the figure. When the finger presses the conductive film 16 to bring the conductive film 16 into contact with the conductive glass 12, "the voltage level at the edge of the conductive film 16 and the conductive glass 12 is changed. By detecting the voltage level values of the four corners of the conductive film 16, the pressure contact position of the finger can be inferred. Basically, the resistive touch panel has the advantages of high resolution, thin thickness, low power consumption, low price, convenient operation, etc., but has poor light transmittance, poor durability, low accuracy, and is difficult for the user to carry out with fingers. Operation, but the need to use the stylus to enter and other shortcomings. [0006] ^ _ . Referring to the second figure, a schematic diagram of a capacitive touch panel of the prior art is shown. The capacitive touch panel 2 is mainly composed of a glass substrate 22, and a conductive plating layer 24 and a scratch-resistant coating film 26 are sequentially formed on the upper surface of the glass substrate 22, and the glass substrate 22 is under the glass substrate 22. The surface is made of - an electromagnetic shielding layer 28. The conductive plating layer 24 is applied with a uniform electric field, and when the finger touches the surface of the touch panel 2, a coupling capacitor is formed between the finger and the conductive plating layer 24 to generate a current. By detecting the magnitude and direction of this current, the finger's pressure contact position can be determined. The advantages of capacitive type are dustproof, fireproof, scratch-resistant, and high resolution, but they are expensive, easy to generate money due to static electricity or fishing. The average user touches the input with a finger, so it is not easy to make a more enteric input. And so on. To solve the problems of the above-mentioned resistive or capacitive touch panel. The inventor has been engaged in research and many practical experiences for many years, and has been researched and designed by a plurality of parties. The present invention proposes that the touch panel structure and the input method thereof are the aforementioned implementation and basis.
