A kind of static icon's buffer
touchpad, install on control device, the installation chamber is opened on the control device, the buffer
touchpad can be detachably installed in the installation chamber, the buffer
touchpad includes circuit substrate, support plate is also installed on the circuit substrate by connecting column, composite frame is arranged on the support plate, touch component is installed in the composite frame, the touch component is transparent layer structure, five
layers of transparent touch layer are glued in the multistage step of composite frame in the scheme, and are installed layer by layer, structure is more compact;Wherein protective layer can reduce touch damage, buffer layer uses the double shock-absorbing design of spring and
silica gel support column, solve the pain point that traditional resistance touch screen is easily damaged, icon layer can show different static icons under the action of backlight layer, finally
diamond grid
on resistance sensing layer can directly locate touch point coordinates by resistance change, and information is transmitted to circuit substrate, realizes touch control.
