The second panel 11, 13 is electrically conductively connected to the control unit 4G, and generates an electric field that acts positively on the electronic ink 12, and the first panel 11 is a soft transparent panel. The electronic ink layer I2 is made of a coffee slab with an optical bistable 1300190, which can be changed by the seam force and the electric field side, thereby changing the optical characteristics. The second panel 13 is coated with a dark color ^ The tiring (four) plate is also susceptible to partial pressure and is deformed accordingly. When the water layer 12 has a permeable layer, the electronic board displays the color of the pigment applied by the second panel 13. = stylus 2G It does not have electrical and ink pigments, and its nib portion is a two-dimensional writing head 21, - Figure reference, the optical characteristics of the (4) sub-ink layer 12 can be changed on the first panel n, thereby writing the electronic board, and the electronic board is not damaged due to excessive pressure. The detecting unit 30 is disposed under the electronic board 10 and has an inductive circuit. The sensing circuit 31 is disposed corresponding to the second panel 13 and is formed by using material properties of the panel. A conventional resistive touch screen 'When the second panel 13 is under pressure, the sensing circuit should generate 15 electrical nicknames for delivery to the control unit 40. • The control unit 40 has an input The group 41, a control circuit 42 and an output group 43 are electrically connected to the control circuit 42. The input group 41 is for the user to operate. The input interface includes a function interface for displaying or clearing the written message, and a force month b; i surface for outputting or storing the coordinate signal generated by the writing terminal from the output terminal group, the control circuit 42 receives all the coming from The input group 41 operates privately and can Supplying a voltage having a high and low potential difference to the two panels 11, 13 and controlling the electrical actuation of the detecting unit 30, and converting the electrical nickname transmitted by the sensing circuit 31 into the coordinate signal; the output terminal group 43 It is a USB transmission interface that can be connected to a storage device or a computer device. Therefore, the coordinate signal can be stored by connecting a USB disk, or by connecting a computer such as a PDA. The touch panel 1 is used as an input interface for the document processing. Therefore, when the user sets the touch panel to operate in the writing mode through the input terminal group 41, the control circuit 42 first sends a short voltage to the second panel γ. 13. Rearranging the liquid crystal molecular structure of the electronic ink layer 12 so as to return to no light transmission (4) clearing the electronic board 1G ± unnecessary noise is displayed, when the stylus 20 is pressed on the electronic board 10 When writing, since the optical characteristics of the electronic ink layer 12 are changed to be translucent, the part of the writing can reflect the color of the pigment of the second panel 13 and clearly show the imperfection of writing; second The panel 13 senses the pressure of the stylus pen 2, and thus touches the detecting unit 30, so that the sensing circuit 31 correspondingly generates a writing partial electrical signal and is received and processed by the control unit 4; 15 ^ In the input group setting, the written message is singularly outputted from the output group, and the control circuit 42 processes the sensor according to the instruction: the conversion is processed into a coordinate signal, and is stored according to the instruction. Or straight out, if the user clears the written message in the input group 41, the circuit: 1 circuit 42 sends a voltage according to the operation command to the second panel n, work,: in addition to the written message on the electronic board 10 .
