    Abstract: A reading method and a reading device for a two-dimensional code. The method includes: capturing a two-dimensional code image through an image capturing device; detecting an outer frame and a position mark of a two-dimensional code in a skewed state in the two-dimensional code image; restoring the two-dimensional code in the skewed state to a default state; and performing a default operation according to the two-dimensional code in the default state.

    Abstract: A touch control device including a touchpad, a first driving circuit and a system circuit is provided. The first driving circuit is coupled to the touchpad for driving the touchpad to detect a sensed value frame of a touch event on the touchpad. The system circuit is coupled to the first driving circuit for analyzing the sensed value frame provided by the first driving circuit to recognize a first finger position, a second finger position and a third finger position, and defining the first finger position as a left key position of a virtual mouse, the second finger position as a right key position of the virtual mouse according to a position relationship among the first finger position, the second finger position and the third finger position. An operating method of a touch control device is also provided.

    Abstract: An electronic device includes: at least one connection interface, to receive an external signal. A first signal switching multiplexer is connected to the connection interface. A laptop system is connected to the first signal switching multiplexer, to operate in a laptop mode. A drawing board system is connected to the first signal switching multiplexer, to operate in a drawing board mode and an independent screen mode. A switching switch generates a switching signal and transmits it to the first signal switching multiplexer, the laptop system, and the drawing board system, to select the laptop mode, the drawing board mode, or the independent screen mode.
