Description

Touch panel Technical Field The utility model relates to the field of touch panels, in particular to a touch panel. Background The touch panel is also called a touch screen and a touch panel, and is an induction type liquid crystal display device capable of receiving input signals such as a contact and the like, and the touch panel is mainly applied to mobile phones, tablet computers, cash registers, industrial fields and the like. The resistive touch screen has the following working principle that when a finger of a person presses the surface of the touch screen, the elastic PET film can be bent downwards, so that the upper ITO coating and the lower ITO coating can be contacted with each other to form a touch point, and the voltage of the touch point is detected by an ADC (analog to digital converter) to calculate and calculate X, Y axis coordinate values. And the capacitive touch screen works by utilizing current induction of a human body. When a finger touches the capacitive screen, the capacitance of the finger is superimposed on the capacitance of the screen body, and at the moment, the self-capacitive screen respectively determines a transverse coordinate and a longitudinal coordinate according to the change of the capacitance before and after touching by detecting the transverse electrode array and the longitudinal electrode array, and then the transverse coordinate and the longitudinal coordinate are combined into a planar touch coordinate. The operation panel on the touch panel is fixed on the circuit board through the screw, when the components and parts on the circuit board need to be maintained, the external tool is needed, and when no tool exists, the operation panel can not be disassembled, and the phenomenon of sliding wire easily occurs in the mode of screw connection, so that the difficulty of disassembling and maintaining the touch panel is increased. Disclosure of utility model The utility model aims to provide a touch panel, which solves the defects that when the operation panel in the background technology is maintained, an external tool is needed, and when no tool is available, the operation panel cannot be disassembled, and a thread slipping phenomenon easily occurs in a screwing mode, so that the difficulty of disassembling and maintaining the touch panel is increased.
