Description

523716 V. Description of the Invention (1) [Field of the Invention] The present invention relates to a notebook computer, particularly a notebook computer with a handwriting input device built into a liquid crystal display module. [Background of the Invention] At present, personal computers are becoming more and more popular, and it seems to have become a necessity for work or life. Users also have higher and higher requirements for convenience in use of computers. In addition to being small and portable, they also need to be portable. With fast and easy to learn input methods, whether it is getting lighter, thinner, shorter, smaller notebook computers, or more and more convenient input methods, it is an inevitable development trend of personal computers. At present, general input methods need to memorize their radicals before use. Each input method has different radicals and its word splitting principles. The difficulty and complexity of memorizing radicals and word splitting principles makes it very difficult for beginners to get started ^ and Because handwriting input does not need to memorize roots and word-breaking principles, it is very easy for beginners to learn, and the next-generation operating system (Windows XP) already supports handwriting recognition, officially announcing the era of handwriting input. The following is simple for the current practice Instructions. Please refer to FIG. 1, which shows a notebook computer with a handwriting input device. As shown in FIG. 1, these notebook computers may include a notebook computer host 100 and a sensing device 1 0 1 The two are coupled to each other and have a foldable joint (not shown) design, so that when not in use, it can be folded into a suitcase-like appearance for easy carrying. The surface of the sensing device 1 0 1 can be used as a sensing platform 10 2. When handwriting input is used, the notebook computer needs to be expanded to the state shown in FIG. 1, and then the touch pen 1 0 3 is used for sensing. The sensing platform 1 0 2 on the device 1 0 1 writes, so that the sensing device 1 0 1 can be based on

523716 V. Description of the invention (2) The pressure change on the sensing platform 10 2 generates a sensing signal corresponding to the running performance of the touch pen 103 to learn the handwriting written by the user. Then, the computer can convert the sensing signal into a storable data type and store it in the hard disk or memory to complete the handwriting input action. Of course, in order to meet the writing habits of ordinary people, users can also place general paper on the sensing platform 102, and use conventional pens (such as pencils, ball pens, or steel ball pens) to write on the sensing platform. , So that users can clearly know what has been written; since the thickness of general paper is quite thin and the sensitivity of the sensing platform to pressure changes is extremely high, these methods will not affect the operation of the sensing device 101.

From the above description, we can know that although the conventional handwriting input equipment can successfully complete the handwriting input action, because the volume of the sensing device is too large, it is a burden for the user. When using it with a notebook computer, This situation is very obvious. If in a narrow environment, such as on an airplane, in a conference room, etc., you must expand the handwriting input function of the notebook computer to use it in a limited space. It is a very inconvenient design; in addition, users do not need their handwriting input function every time they use a notebook computer, so when users do not need handwriting input, they still have to endure the handwriting input device. Bulky and cumbersome. Because of the blind spots of the current handwriting input equipment mentioned above, although the handwriting input technology has gradually matured, it still cannot become the mainstream input method. [Objective and Summary of the Invention] In view of this, the object of the present invention is to provide a device with handwriting input.

Page 5 523716 V. Description of the invention (3) The notebook computer with the device is more space-saving and more convenient to use than the traditional method.

According to the purpose of the present invention, a notebook computer with a handwriting input device is provided, which includes an LCD module, a system bus, a system power supply, and a handwriting input device. The handwriting input device further includes a sensing board, a sensing pen, and a control module. group. When designing, the sensing board is built into the LCD module, and the surface of the LCD module is used as a sensing platform to save space. When the sensing pen is writing on the sensing platform, the sensing pen can be coupled to the sensing board by means of electromagnetic induction. In this way, the sensing board can generate a corresponding sensing signal according to the operating track of the sensing pen. The sensing signal is converted into identifiable data through the control module for storage; of course, the sensing pen can be designed to have a refill that can trace visible traces when designing, and use ordinary paper on the LCD module during use. , So that users can see the written handwriting, in line with the writing habits of ordinary people. Furthermore, because the handwriting input device of the present invention has an independent memory and a power switch, it can still work normally when the notebook computer is turned off; moreover, both the front and back sides of the sensing board have sensing functions, and The notebook computer contains a chip that can convert the induction signal into an inverted signal, so users can achieve handwriting input regardless of writing on the front or back of the LCD module.

In order to make the above-mentioned objects, features, and advantages of the present invention more comprehensible, a preferred embodiment is given below and described in detail with the accompanying drawings. [Preferred Embodiment] To improve the shortcomings of the traditional handwriting input device, its built-in

Page 6 523716 V. Description of the invention (4) It is a feasible method in the notebook computer. The present invention builds it in a liquid crystal display (L i qu id Crys ta 1 D i sp 1 ay, hereinafter referred to as LCD) mode. In the group, in addition to reducing the space occupied, both the front and back of the LCD module are smooth surfaces, and can also serve as a writing platform. Please refer to FIG. 2A, which shows a schematic diagram of an LCD module and a sensing pen with a built-in sensing board. Using this figure as an example, the LCD module may include a housing 210, a sensing board 220, and an LCD panel 2. 3 0 and display screen 240, the sensor board 22 0 can be arranged between the housing 2 10 and the LCD panel 230 during assembly. On the other hand, the sensing pen 201 may include a pen shaft 202 and a pen core 203. The pen shaft 2 02 further includes an electromagnetic coil (not shown). After the pen shaft 202 is combined with the pen core 203 In addition to being used as an input tool for handwriting input, it can also be written on general paper. In order to facilitate writing on general paper, this refill 2 03 can be an ink tube, such as a ballpoint pen. It should be noted that the sensing board 2 2 0 and the sensing pen 2 0 1 are coupled in an electromagnetic induction manner, that is, in design, the polarity of the sensing pen 2 0 1 and the sensing board 2 The polarity of 2 0 is opposite. For example, the sensing pen 2 01 has a positive electromagnetic signal, and the sensing plate 2 2 0 has a negative electromagnetic signal. Therefore, when the sensing pen 201 is close to the sensing plate 2 2 0 When the two electromagnetic signals of different polarities are coupled to each other to generate an induction signal; if the position of the sensing pen is changed, the type of the induction signal will also be changed accordingly, so as long as the induction signal is processed, it can be obtained The operation of the sensory pen 2 01 is performed. In addition, since the sensing board 2 2 0 and the sensing pen 2 〇1 are connected by electromagnetic induction, even when the handwriting input is performed, the sensing pen 2 〇1 is written on the housing 210 and is not connected with the sensing. The board 220 is in direct contact, but through electromagnetic induction, the writing on the sensing board 2 2 0 can still detect the handwriting written by the sensing pen 2 01;

523716 V. Description of the invention (5) means that the user can regard the housing 210 as having a sensing area 2 11 for writing by the sensing pen 201, and its size is about the same as the area of the sensing plate 2 2 0. When the sensing pen 201 writes in the sensing area 21 1, the 'sensing board 2 2 0' knows the written handwriting. Of course, if both the front and back sides of the sensing board 2 220 have sensing functions, the user can also write on the display screen 2 40 to achieve the purpose of handwriting input. In terms of power management, the switch 2 2 1 can be configured on the side of the sensor board 2 2 0 during design, and coupled to the system power of the notebook computer through a power cord, and also configured on the side of the housing 2 10 There is a power switch jack 2 1 2 and a power switch button 2 1 3. When the power switch button 2 1 3 is pressed, the power switch 2 2 1 can be touched to control the handwriting input device to be turned on or off. Therefore, even a notebook computer If the computer is not turned on, you can still get power directly from the system power of the notebook computer, so you can work without the notebook computer. Of course, if the handwriting input device has a power supply system independent of the notebook computer, this purpose can also be achieved. Then refer to Figure 2B, which shows the position where the sensing board 2 2 0 is built in the L c D module. Taking this figure as an example, the θ I between the sensing board 22 and the LCD panel 230 is called “* / V and μ 邴 罟”.
