LCD Touch Screen, also known as a touch panel, is an inductive liquid crystal display device that can receive input signals such as contacts. The tactile feedback system on the screen can drive each graphic button when touched. A connecting device can be used to replace the mechanical button panel and generate vibrant audio-visual effects via the liquid crystal display screen. The liquid crystal touch screen has gradually replaced the keyboard as a popular human-computer interaction tool for embedded systems due to its portability, small footprint, convenience, and flexibility. The touch screen, as the most recent computer input device, is currently the simplest, most convenient, and natural method of human-computer interaction. It gives multimedia a new look and is an extremely appealing new multimedia interactive device. According to their technical principles, touch screens are classified into five categories: vector pressure sensing, resistive, capacitive, infrared, and surface acoustic wave. Resistive touch screens are the most commonly used in embedded systems. LCD Touch screen applications have rapidly expanded from small commercial markets such as bank ATMs and industrial computers to mobile phones, GPS (Global Positioning System), MP3, and even tablet computers (UMPC) and other consumer electronics fields.
