The sensor 12 can be one of a resistive sensor, a capacitive sensor, or an optical sensor, and can also be an image sensor. The sensor 12 is arranged on the screen 11 to sense gestures. When the sensor 12 is a resistive sensor, a capacitive sensor or an optical sensor, it is arranged inside the screen 11 to sense the finger position of the gesture and simultaneously capture To capture the position of the finger of the gesture, when the sensor 12 is an image sensor, such as a camera lens, it is arranged around the screen 11 to sense the image of the gesture and capture the image of the gesture at the same time.

The controller 13 is electrically connected to the sensor 12. The controller 13 also includes an arithmetic logic unit 131, an identification unit 132, and a memory 133. The arithmetic logic unit 131 is used to perform binary arithmetic operations. The memory 133 stores finger positions or images of gesture samples. , the controller 13 receives the finger position or image of the gesture from the sensor 12 to use the arithmetic logic unit 131 and the recognition unit 132 to judge the gesture and the gesture sample, and compare the finger positions or images of the two, if the two are the same Then an interrupt signal is output. The finger position or image of the gesture sample can be transmitted to the memory 133 via a Universal Serial Bus (USB) transmission line for storage. Wherein, the memory 133 can be a read-only memory (Read Only Memory, ROM), a programmable read-only memory (Programmable Read Only Memory, PROM), an erasable programmable read-only memory (Erasable Programmable Read Only Memory, EPROM), an electronic One of Electrically Erasable Programmable Read Only Memory (EEPROM) or Flash ROM.

The image processor (Scaler) 14 is electrically connected to the controller 13. After the image processor receives an interrupt signal from the controller 13, it outputs a switch signal to the screen 11 to control the power supply of the screen 11, and then controls the screen 11 to switch.
