ABSTRACT:
An active matrix-type display apparatus comprises: pixel circuits arranged in a row and a column directions; a column current control circuit that generates a current signal; an information line that transmits the current signal from the column current control circuit to the pixel circuits arranged in the column direction; and a light emitting element that is supplied with current corresponding to the current signal, from one of the pixel circuits, wherein the column current control circuit has an information storage circuit and compares an information stored in the information storage circuit with an information newly input into the column current control circuit, converts the newly input information to a converted information according to the comparison result and generates the current signal on the basis of the converted information.
