Touch pad with press pressure detection

Abstract

The invention discloses a touch control plate with press pressure detection, especially providing a touch control plate that detecting the different press pressures of finger to find the press motions. It at least comprises: one touch control plate; one piezoelectric ceramic plate and one voltage detecting circuit; said touch control plate can detect the finger touch and move signals, and using one microprocessor of voltage detecting circuit to judge the change of voltage difference that transformed by the press pressure via piezoelectric ceramic plate, to find the press motion of operator, to control the motion of cursor and control the input of key-press.

Description

technical field [0001] A touch panel with pressing pressure detection, especially a touch panel that can detect different pressing pressure paths of fingers to confirm the pressing action, so as to control the movement of the cursor and serve as an input controller for key function buttons. Background technique [0002] The touchpad used in notebook computers to control the screen cursor is used as a cursor controller to drive the movement of the screen cursor because it has the function of detecting finger contact and movement. It has a small size and a small area. Advantages, so it has become the basic equipment of notebook computers, and the touch panel can be roughly divided into capacitive or resistive. After the coordinate calculation, the center position of the finger contact area and its displacement are obtained, and the displacement is converted into the displacement of the screen cursor, which is used to control the movement of the cursor. [0003] Although the t...

Problems solved by technology

[0003] Although the touchpad has the convenience of moving the cursor quickly, when the cursor moves to a certain function button (icon) on the screen, to select or activate the function button, it also needs to be used in conjunction with the touchpad Buttons, because the fingers have to control the cursor on the one hand and watch the buttons to complete the pressing of the buttons, which is still inconvenient in operation; in addition, some touchpad drivers provide users with fast and continuous clicks of touch with fingers. panel to replace additional buttons, although it can improve the convenience of use, but its convenience is still not as convenient as moving the cursor to a certain item and pressing it directly; moreover, if the operation of Windows is unified, the cursor controller It has different functions from the left button and the right button. Continuous and quick clicking can only replace the function of the left button, but cannot replace the function of the right button. There are still gaps in use.
