Description

Notebook computer with handwriting input device

technical field

The invention relates to a computer, especially a notebook computer with a handwriting input device.

Background technique

At present, personal computers are becoming more and more popular, and have become a necessity for work or life. Users have higher and higher requirements for the convenience of computer use. The input device, whether it is a notebook computer that is becoming lighter, thinner, shorter, or smaller, or an input method that is more and more convenient, is an inevitable development trend of personal computers. At present, the general input method needs to memorize its root before using it. The root and its splitting principle of each input method are different. The difficulty and complexity of memorizing the root and splitting principle make it very difficult for beginners to learn. , and handwriting input does not need to memorize the root and the principle of splitting characters, so it is very easy for beginners to get started, and the next generation of operating systems can already support handwriting recognition, officially announcing the advent of the era of handwriting input. The following is a brief description of the current situation.

As shown in FIG. 1 , it is a three-dimensional schematic view of a notebook computer equipped with a handwriting input device. These notebook computers may include a computer host 100 and a sensing device 101, which are connected to each other and have a foldable joint (not shown). As shown), it can be folded into a suitcase-like device when not in use for easy portability. The surface of the sensing device 101 can be used as the sensing platform 102. When adopting handwriting input, the notebook computer needs to be unfolded into the state shown in FIG. 102, so that the sensing device 101 can generate a sensing signal corresponding to the running track of the stylus 103 according to the pressure change on the sensing platform 102, so as to know the handwriting written by the user. Then, the computer can convert the sensing signal into storable data, and store it in the hard disk or memory, to complete the operation of handwriting input. Of course, in order to conform to the writing habits of ordinary people, the user can also place ordinary paper on the sensing platform 102, and use a customary pen (such as a pencil, ball pen or ball pen, etc.) that can draw on the paper to write on the paper, so that The user can clearly know what the other party has written. Since the general paper is quite thin and the sensing platform is highly sensitive to pressure changes, these methods will not affect the sensing effect of the sensing device 101 .

From the above description, we can see that although the current handwriting input device can successfully complete the handwriting input, it is a burden for the user due to the large size of the sensing device. This situation is very obvious. If you want to use the handwriting input function of a notebook computer in a narrow environment, such as on an airplane, in a conference room, etc., you must unfold it. In addition, the user does not need the function of handwriting input every time he uses a notebook computer, so when the user does not need handwriting input, he still has to endure the bulkiness of the handwriting input device The inconvenience caused by the volume is just because of the various problems mentioned above, although the handwriting input technology has gradually matured, it still cannot be used as a mainstream input method.

Detailed ways

As shown in FIG. 2A, it is a schematic diagram of a liquid crystal display module with a built-in sensing board and a sensing pen, wherein the liquid crystal display module may include a housing 210, a sensing board 220, a liquid crystal display panel 230 and a display screen 240, During assembly, the sensing board 220 can be disposed between the casing 210 and the liquid crystal display panel 230 . On the other hand, the sensing pen 201 may include a pen holder 202 and a pen core 203 . On the other hand, the sensing pen 201 can include a pen holder 202 and a refill 203, wherein the pen holder 202 further includes an electromagnetic coil (not shown). After the pen holder 202 and the refill 203 are combined, it can be used as an input tool for handwriting input , can also write on general paper, for the convenience of writing on general paper, this refill 203 can be ink tube, such as atomic pen refill etc. It should be noted that the sensing board 220 and the sensing pen 201 are assembled in the form of electromagnetic induction, that is, in design, the polarity of the sensing pen 201 can be opposite to that of the sensing board 220. For example, the sensing pen 201 has a positive electromagnetic signal, and the sensing plate 220 has a negative electromagnetic signal. Therefore, when the sensing pen 201 is close to the sensing plate 220, the two electromagnetic signals of different polarities will be They will be coupled with each other to generate sensing signals; if the position of the sensing pen changes, the shape of the sensing signal will also change accordingly, so as long as the sensing signals are processed, the running track of the sensing pen 201 can be known. Moreover, since there is electromagnetic induction between the sensing board 220 and the sensing pen 201, the sensing board 220 can still detect the handwriting written by the sensing pen 201; A sensing area 211 for writing by the sensing pen 201 is approximately equal to the area of the sensing plate 220. When the sensing pen 201 writes in the sensing area 211, the sensing plate 220 can know all written handwriting. Of course, if both the front and back sides of the sensing board 220 have sensing functions, the user can also write on the display screen 240 to achieve the purpose of handwriting input. In terms of power management, the switch 221 can be arranged on the side of the sensing board 220, and can be connected to the system power supply of the notebook computer through a power cord. At the same time, a power switch jack 212 and a power switch are also arranged on the side of the casing 210. Button 213, when the power switch button 213 is pressed, the power switch 221 can be touched to control the opening or closing of the handwriting input device. Therefore, even if the notebook computer is not powered on, it can still directly obtain power from the system power supply of the notebook computer supply, so it can work when the notebook computer is not powered on. Of course, if the handwriting input device has a power supply system independent of the notebook computer, this purpose can also be achieved.

As shown in FIG. 2B , it is the position where the sensor board 220 is built into the liquid crystal display module. Taking this figure as an example, the sensing board 220 is disposed between the casing 210 and the liquid crystal display panel 230. It should be noted that this figure only illustrates the position of the sensing board 220 and cannot be used to limit the manufacture of this liquid crystal display module. sequence or method.

As shown in FIG. 3A , it is a schematic diagram of the relationship between the handwriting input device 301 and the notebook computer. The handwriting input device 301 can include a main function device 300 and a switch 221. When the switch 221 is turned on, the system power supply 302 of the notebook computer can provide the power required for the handwriting input device 301 to work. No matter whether the notebook computer is turned on or not, the handwriting input device All can work normally (in another embodiment, the handwriting input device has an independent power supply system). During handwriting input, the sensing pen 201 can be used to write on the sensing area 211, and the main function device 300 is used to convert the sensing signal into recognizable data, which is stored in the storage device 304 through the system bus 303 (handwriting input device It is electrically connected to the notebook computer through RS-232 or USB port) to facilitate subsequent data processing. Wherein, the storage device 304 may be a hard disk, a random access memory (RAM), a dynamic random access memory (DRAM), and the like. The main functional device 300 will be described below with reference to the accompanying drawings.

As shown in FIG. 3B , it shows a circuit block diagram of the main functional device 300 in FIG. 3A . The main functional device 300 may include a sensor board 220 and a control module 310 , wherein the control module 310 includes a controller 311 and a memory 312 . As mentioned above, when the sensing pen 201 writes in the sensing area 211, the sensing board 220 can generate the sensing signal 313 corresponding to the writing, and then the sensing board 220 sends the sensing signal 313 to the controller 311, if so When the notebook computer is not turned on, the controller 311 converts the sensing signal 313 into identifiable data 314, and then feeds it into the memory 312 for temporary storage, and then reads out the identifiable data 314 in the memory 312 when the notebook computer is turned on. sent to the system bus 303 and fed into the storage device 304 for storage. If the sensing signal 313 is measured from the back of the sensing board 220 , the sensing signal 313 needs to be processed by a chip (not shown) in the notebook computer to convert the signal into an inverted signal. It should be noted that the memory 312 can be any non-volatile memory, such as flash memory or electrically erasable programmable read-only memory (EEPROM), to avoid data loss after the handwriting input device is turned off.

The invention is applied to the built-in liquid crystal display module of the handwriting input device, which not only saves space, but also makes it easier to use because it can be written on both sides. Compared with the existing practice, it has obvious progress.
