Problems solved by technology

Because, in order for the control chip to detect the touch position where the user touches the touch panel, the control chip must be connected to all the touch scanning lines of the touch panel, that is, the signal lines of the touch panel. The chip is set on the circuit board of the electronic device, so the signal line of the touch panel can only be connected to the circuit board through the transmission line, but because the circuit board's circuit cannot be made quite small, it will occupy a large area, so In the case where the circuit board has a certain area limitation, the number of signal lines used by the touch panel to scan the position where the user touches the touch panel is limited, so if the signal lines of the touch panel cannot be increased, That is, the touch accuracy of the touch panel cannot be improved.

Abstract

The invention relates to a modularized touch control panel. The modularized touch control panel comprises a first substrate and a second substrate; the second substrate corresponds to the first substrate; and the touch control panel is integrated with a control chip so as to increase a touch control scanning beam of the touch control panel, reduce the complexity and the occupied area of a signal transmission circuit between an electronic device and the touch control panel and simplify an electronic device circuit. Moreover, the first substrate or the second substrate of the touch control panel is provided with a metal layer so as to reduce impedance and increase signal stability.

Description

technical field [0001] The present invention relates to a touch panel, in particular to a modular touch panel. Background technique [0002] Most of the current electronic devices provide a panel for the user to view the functions provided by the electronic device, so that the user can operate the buttons of the electronic device to execute the functions of the electronic device according to the functions displayed on the panel. In order to make it easier for users to operate electronic devices, electronic device manufacturers now provide touch panels. Touch panels are a typical coordinate input device. Users can use the functions displayed on the simple touch panel, namely The functions provided by the electronic device can be easily executed. [0003] With the increasing speed and efficiency of electronic products, and the emphasis on lightness, thinness, shortness, and smallness, many manufacturers propose modular touch panels to cope with the current development trend. ...
