Abstract:
1. A signal transmission circuit, including: a plurality of signal paths which respectively transmit signals outputted from a plurality of different circuit elements; and an output path formed by connecting the plurality of signal paths, wherein each of the plurality of signal paths includes a buffer element and a switching element which receives an output from the buffer element, the output path is formed by connecting output lines of the switching elements, there is disposed a buffer element in the output path, and wherein any of the switching elements in the plurality of signal paths is turned on according to an operational mode, and then a target signal is selected and outputted to the output path, and wherein each of the different circuit elements is one corresponding only to a final-stage circuit element in a block which sequentially drives a plurality of pixel circuits, when the pixel circuits are driven in a forward or reverse direction, and the operational mode is switched corresponding to the forward or reverse direction of driving the pixel circuits.
