In one embodiment, the touch circuit 140 and the power circuit 150 are disposed parallel to each other, that is, the touch circuit 140 and the power circuit 150 are formed on the board body 100 in a parallel manner, so that the distance between the touch circuit 140 and the power circuit 150 is always greater than zero, so that the touch circuit 140 and the power circuit 150 keep a state of being separated from each other, and the cross probability between the touch circuit 140 and the power circuit 150 is reduced.

Because the first side and the second side are adjacent sides of the control module 200, that is, the first side and the second side are adjacent to each other, the portion of the touch circuit 140, which is far away from the first bonding area 110, is connected to the touch end on the first side of the control module 200, and the portion of the power circuit 150, which is far away from the first bonding area 110, is connected to the power supply end on the second side of the control module 200, so that the portion of the touch circuit 140, which is near the control module 200, and the portion of the power circuit 150, which is near the control module 200, are located on the adjacent sides of the control module 200, and therefore, a space exists between the portion of the touch circuit 140, which is near the control module 200, and the portion of the power circuit 150, which is near the control module 200, is further separated from each other, so that the cross probability that the portion of the touch circuit 140, which is near the control module 200, and the portion of the power circuit 150, which is near the control module 200, is reduced.

The first power supply end corresponding to the first power line 152 and the second power supply end corresponding to the second power line 154 are shorted inside the control module 200, so that the first power line 152 and the second power line 154 are electrically connected, and the current output by the external power supply sequentially passes through the second power line 154, the control module 200 and the first power line 152, and finally supplies power to the display panel, so that the power line 150 is connected with the display panel through the internal wiring of the control module 200, the touch control line 140 is avoided, and the cross probability between the power line 150 and the touch control line 140 is reduced. In one embodiment, the first power line 152 and the second power line 154 are respectively located at two sides of the control module 200, the first power line 152 is located between the control module 200 and the touch panel, and the second power line 154 is located between the control module 200 and the main screen circuit board.
