Background technology
Along with improving constantly of people's living standard, computer has become one of requisite articles for use in people's life, and for easy to carry, the notebook computer that volume is little is used by people especially gradually widely.And compare with desktop computer, although the notebook computer volume is little and easy to carry, but on storage capacity and practicality, or desktop computer is even better, so just cause a lot of people when buying computer, all pacing up and down between desktop computer and notebook computer, is the previous development trend of order with desk type computer integrated therefore.
The utility model content
In order to solve the problems of the technologies described above, the purpose of this utility model provides the computer all-in-one machine of a kind of easy operating and inductive touch control simple in structure.
The technical scheme that the utility model adopts is: a kind of computer all-in-one machine of inductive touch control, comprise shell, the front surface of described shell is provided with LCDs, the inner chamber of described shell is provided with inductive touch control control circuit and host computer module, described inductive touch control control circuit is arranged on the behind of LCDs, and the output terminal of described inductive touch control control circuit is connected by the host computer module and then with the input end of LCDs.
Further, described inductive touch control control circuit comprises the induction dash receiver that is arranged on the LCDs back side, the output terminal of described induction dash receiver is connected with sweep circuit, level comparator, CPU and series bus controller in turn, the output terminal of described series bus controller is connected with the input end of host computer module, another output terminal of described sweep circuit is connected with frequency discriminator, and the output terminal of described frequency discriminator is connected with another input end of CPU.
Further, described LCDs is comprised of TFT glass, display drive circuit and LED-backlit module, and the input end of described display drive circuit is connected with the output terminal of host computer module; Described induction dash receiver is arranged on the back side of LED-backlit module.
The beneficial effects of the utility model are: the utility model is module-integrated with LCDs and host computer, therefore to take volume little for the utility model integral body, need not to take a large amount of placing space, and owing to being provided with the inductive touch control control circuit, therefore need not external keyboard and mouse, easy to carry, and the convenience of operation improves greatly, also have owing to utilizing the inductive touch control control circuit, accuracy and the sensitivity of touch-control control therefore of the present utility model are all improved greatly.
In addition, when writing pencil is stressed when varying in size, when sending the different sensed dash receivers of frequency signal and receiving, the induction dash receiver will produce the oscillating voltage of corresponding frequencies, can determine like this position of writing pencil, and can judge the size of writing strength according to signal frequency, and then realize that the change transitions with hand-written dynamics is the variation of stroke weight, dye-in-the-wood individual character.Also have because the induction dash receiver is installed in the back side of LED-backlit module, thereby overcome the problem of location and displacement, therefore for traditional LCD technology, the color of LED technology of the present utility model is abundanter, and has the advantages such as environmental protection, energy-conservation, the life-span long, product is thinner.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Fig. 1 is the schematic block circuit diagram of the computer all-in-one machine of a kind of inductive touch control of the utility model.
Embodiment
By shown in Figure 1, a kind of computer all-in-one machine of inductive touch control, comprise shell, the front surface of described shell is provided with LCDs, the inner chamber of described shell is provided with inductive touch control control circuit and host computer module, described inductive touch control control circuit is arranged on the behind of LCDs, and the output terminal of described inductive touch control control circuit is connected by the host computer module and then with the input end of LCDs.Described shell is comprised of front frame and bonnet, and described LCDs arranges on the former frame.
Be further used as preferred embodiment, described inductive touch control control circuit comprises the induction dash receiver that is arranged on the LCDs back side, the output terminal of described induction dash receiver is connected with sweep circuit, level comparator, CPU and series bus controller in turn, the output terminal of described series bus controller is connected with the input end of host computer module, another output terminal of described sweep circuit is connected with frequency discriminator, and the output terminal of described frequency discriminator is connected with another input end of CPU.The in the same size of described induction dash receiver and LCDs.
Be further used as preferred embodiment, described LCDs is comprised of TFT glass, display drive circuit and LED-backlit module, and the input end of described display drive circuit is connected with the output terminal of host computer module; Described induction dash receiver is arranged on the back side of LED-backlit module.Described LED-backlit module is arranged on the back side of TFT glass, and in addition, the back side of described induction dash receiver can be provided with the back metal plate.
According to above-mentioned the utility model, its principle of work is: during use, when the writing pencil in the external world in TFT click on glass or when writing, writing pencil can produce the signal of different oscillation frequency because of stressed varying in size, the induction dash receiver receives the signal of this oscillation frequency; Sweep circuit will scan the induction dash receiver by the frequency of 6MHz, to cycle of induction dash receiver run-down be 0.2ms; Level comparator to each scan period interscan to signal and the maximum level signal that has obtained in this cycle carry out level ratio, and then determine that by sweep circuit and level comparator the induction dash receiver receives the position coordinates of signal, and the scan address of its maximum level signal is the position coordinates of writing pencil; With the signal input CPU that receives, the output signal of sweep circuit is also inputted frequency discriminator simultaneously, be converted to the signal of varying level by the signal of the frequency discriminator oscillation frequency that writing pencil is different, carry out analog to digital conversion through CPU, the nib that is about to writing pencil is under pressure and is for conversion into digital signal, CPU inputs the host computer module with the position coordinates signal of input and the digital signal of pressure after series bus controller is converted to the USB serial signal, the host computer module is transported to display drive circuit by the VGA port after the digital signal that receives is processed, and then makes the result behind the TFT glass display touch-control.
