The technology inputted more than existing Digital Drawing and the touch liquid crystal display equipment of writing with electromagnetic induction, it is such
Device, is made up of electromagnetic touch-control screen, LCDs, electromagnetic touch-control system board.Processing and making process, is needed first by liquid crystal
Liquid crystal cells, the backlight module of display screen are unloaded from back-cover, enter to be disassembled with back-cover, by electromagnetic touch-control tablet after disassembling
Load and re-assemblied between backlight module and new back-cover, then in place whether, whether signal transacting is accurate for test position sensing
Really.Due to being interfered between backlight module, back-cover, electromagnetic touch-control tablet, therefore multiple disassembling is needed to assemble and test
The making of electromagnetic touch-control screen could be completed after adjustment.A kind of electromagnetic touch-control equipment as shown in Figure 2, including electromagnetic type are touched
Screen（8）, liquid crystal cells（10）, backlight module（11）, back-cover（12）, touch-control system plate（13）With electromagnetic touch-control tablet（9）.
Needed when making first by liquid crystal cells（10）, backlight module（11）And back-cover（12）Take apart, back-cover is damaged to be needed to make the new back of the body after block
Lid, then by electromagnetic touch-control tablet（9）Load backlight module（11）With new back-cover（12）In, reposition touch-control system
Plate（13）, matching test is carried out with adjustment until precision reaches standard requirement.
And existing capacitance digital is drawn and the touch liquid crystal display of writing, because touch-control glass capacitance sensing pad is set
Meter is not enough, and the line sensing in drawing or writing is not good, it is impossible to the state of nature pen is presented.
The content of the invention
The invention is intended to provide a kind of capacitance digital to draw and book apparatus, existing touch liquid crystal display device processing procedure is solved
Complex process, shortens processing time and reduces cost.
In order to solve the above problems, the present invention proposes that capacitance digital is drawn and writing device, including active capacitance pen,
Touch-screen, LCDs and Trackpad, the touch-screen are in projected capacitive multipoint capacitive touch screen, the touch-screen
Provided with transparent etched circuit, set below touch-screen and set Trackpad, the Trackpad below LCDs, the LCDs
For capacitive touch control plate, the transparent etched circuit electrically connects and integrated chip is provided with the Trackpad, the Trackpad, described
Transparent etched circuit includes the capacitance sensing pad horizontal line group for sending signal and the capacitance sensing pad for receiving signal
Vertical line group.
Further, a kind of capacitance digital is drawn and writing device, and the written place of the active capacitance pen is provided with
Pressure sensor device.
Further, a kind of capacitance digital is drawn and writing device, the projected capacitive multi-point capacitive touch screen
For P-CAP multiple spot capacitance type touch control screens.
Further, a kind of capacitance plate Digital Drawing and writing device, the capacitance sensing pad horizontal line group and electric capacity
It is averagely to be equally spaced to sense vertical line group.
The present invention solves electromagnetic touch-control liquid crystal display processing procedure complexity, and processing is inconvenient, and production efficiency is low and cost is high
The problem of.
