摘要： An image signal processing method adapted to an AFE device, which respectively generates first and second colors of digital signals according to first and second colors of analog signals. First, the first color of odd and even signals and the second color of odd and even signals are generated according to the first and second colors of analog signals, respectively. In a single channel mode, the first color of odd or even signal serves as the first color of digital signal for output, and the second color of odd or even signal serves as the second color of digital signal for output. In a dual channel mode, the first color of odd signal and second color of even signal are synchronously outputted, and the first color of even signal and second color of odd signal are also synchronously outputted. The first color of odd and even signals are combined to form the first color of digital signal, and the second color of odd and even signals are combined to form the second color of digital signal.

摘要： The present disclosure relates to a touch device, and more particularly to a pattern of a capacitive touch device and a manufacturing method thereof. The pattern of the capacitive touch device comprises of a substrate, two adjacent first axial electrodes, a first axial conductive wire, and a pair of metal jumpers. The first axial conductive wire is disposed between the two adjacent first axial electrodes for connecting the two adjacent first axial electrodes. The pair of metallic metal jumpers is disposed on the connecting points of the two first axial electrodes and the first axial conductive wire. Accordingly, resistance caused by the connecting points of the two adjacent first axial electrodes and the first axial conductive wire can be reduced such that response speed of the pattern of the capacitive touch control device is increased.
