Abstract:
Disclosed is a smart tablet (100) with a capacitive touch screen. The smart tablet comprises: a complete machine (10), a capacitive touch screen (20), a liquid crystal display panel (30) and an isolator (40), wherein the liquid crystal display panel (30) is arranged between the complete machine (10) and the capacitive touch screen (20); the complete machine (10) comprises a power source (11), a TV main board (12), a capacitive touch screen control board (13) and a liquid crystal screen drive board (14); the power source (11) is connected to the TV main board (12); the liquid crystal screen drive board (14) is connected to the liquid crystal display panel (30) and the TV main board (12); the capacitive touch screen control board (13) is connected to the capacitive touch screen (20); and the capacitive touch screen control board (13) is provided with a first interface, the TV main board (12) is provided with a second interface, and the first interface is connected to the second interface by means of the isolator (40). By means of adding the isolator (40) to isolate the complete machine (10) from the capacitive touch screen (20), the grounding interference suffered by the complete machine (10) cannot be transferred to the capacitive touch screen (20), thus ensuring stable operation of the capacitive touch screen (20).
