INSTRUCTIONS: 1. Field of the Invention The present invention relates to a wireless transmitter, and more particularly to a wireless transmitter that is mounted on a touch screen to form a two-way signal transmission. ° [Prior Art] Computer systems are widely used in the calculation and storage of digital data, such as industrial computers, personal computers, and notebook computers. In general, in addition to being used as information computing and library storage, the computer system further includes a display device for the user to read the message, and an input device for inputting the command or signal. In the case of a personal computer, the display device can be an e-panel display, and the input device can be a keyboard or a mouse. Although this type of input device is generally accepted by the public, it is still indirectly moved or selected by the input device to display the indicator displayed on the display device. The user must first familiarize with the operation mode of the input device to improve. The speed or efficiency of operation creates a development in touch screen technology that can operate directly on display devices. Commonly used touch screens include resistive touch screens and capacitive touch screens, with resistive touch screens being the most used. The resistive touch screen is mainly composed of a soft plastic film (such as a pet film) coated with an Indium Tin Oxide (ITO) layer and glass, and is separated by a Space Dot. When the upper flexible plastic film is pressed, the ITO layer on the soft plastic mold contacts the ITO layer on the glass to conduct an electrical signal, and the electrical signal is transmitted to a controller to calculate the pressing coordinate and present Touch on the screen. Traditionally, a computer system equipped with a touch screen must rely on a transmission line, a physical connection port, or even a touch screen directly placed in a computer system to transmit signals between the touch screen and the computer system, such as US 7,327,353, US 20060250975 patent; that is, the user must be in close proximity to the computer system to input signals through the touch screen.
