Description

Technical Field

[0001] This utility model relates to the field of touch panels, specifically a touch panel. Background Technology

[0002] A touch panel, also known as a "touchscreen," is a sensor-based liquid crystal display device that can receive input signals from touch. Its main applications include mobile phones, tablets, cash registers, and industrial applications. Its working principle is as follows: Resistive touchscreen: When a finger presses on the touchscreen surface, the elastic PET film bends downwards, allowing the upper and lower ITO coatings to contact each other and form a touch point. An ADC (Analog-to-Digital Converter) is used to detect the voltage at this point to calculate the X and Y axis coordinates. Capacitive touchscreen: This type of touchscreen works by sensing the electrical current of the human body. When a finger touches the capacitive screen, the finger's capacitance is added to the screen's capacitance. The capacitive screen then detects the changes in capacitance before and after the touch by using horizontal and vertical electrode arrays to determine the horizontal and vertical coordinates, which are then combined to form the planar touch coordinates.

[0003] The control panel on the touch panel is fixed to the circuit board with screws. When it is necessary to repair the components on the circuit board, external tools are required. Without tools, it is impossible to disassemble. The screw connection is prone to stripping, which further increases the difficulty of disassembling and repairing the touch panel.

At the same time, the cross section of the limiting groove is set as a right trapezoid, and the limiting block is inserted into the inside of the limiting groove.

[0011] Preferably, the operation panel covers the surface of the circuit board and is positioned and installed by positioning grooves, positioning pieces, limiting grooves, and limiting blocks, and the operation panel on the surface of the circuit board has a pull-out structure.
