Abstract: The present invention is a novel touch screen concept of a liquid crystal display of an electrical device, which combines a replaceable wireless sensing chip with an electrical device circuit chip to form a double-layer chip power supply sensing structure. The electrical device circuit chip supplies electrical power to the wireless sensing chip for operation through the double-layer chip power supply sensing structure. The wireless sensing chip can be controlled through the double-layer power supply sensing structure to transmit and receive radio waves for wireless touch control, such that liquid crystal display operations of the electrical device does not require a conventional touch apparatus. The present invention is to arrange a wireless sensing chip system in an electrical device. The wireless sensing chip system is provided therein with a central processor circuit and wireless sensing chip, a plurality of large circuit and wireless sensing chip, and a plurality of small circuit and wireless sensing chip. Wherein, the central processor circuit and wireless sensing chip is a double-layer central processor chip power supply sensing structure composed of an upper layer wireless sensing chip and a lower layer central processor circuit chip; the large circuit and wireless sensing chip is a double-layer large chip power supply sensing structure composed of an upper layer wireless sensing chip and a lower layer large circuit chip; and the small circuit and wireless sensing chip is a double-layer small chip power supply sensing structure composed of an upper layer wireless sensing chip and a lower layer small circuit chip. Each of the lower layer circuit chips can receive an external electrical power source for electrical power supply (circuit chip power supply), and the lower layer circuit chip supplies electrical power to the upper layer wireless sensing chip through the double-layer chip power supply sensing structure. Each of the upper layer wireless sensing chips can be controlled by the central processor circuit chip through the double-layer chip power supply sensing structure, so as to transmit and receive radio waves for wireless touch control (the wireless sensing chip transmits and receives radio waves). In addition, the upper layer wireless sensing chip can be mechanically connected and electrically connected with the lower layer circuit chip for supplying power to the wireless sensing chip (the wireless sensing chip transmits and receives radio waves). The upper layer wireless sensing chip can be mechanically separated and electrically separated from the lower layer circuit chip for replacing the wireless sensing chip (the wireless sensing chip is replaceable). As such, by using the replaceable wireless touch control chip system of the present invention, an electrical device can use an internal replaceable wireless sensing chip for wireless touch control of a liquid crystal display. The liquid crystal display operation of the electrical device does not require a conventional touch apparatus.
