A method for manufacturing an electrode for a display apparatus includes printing and drying a conductive paste on a substrate, and printing a glass paste on the dried conductive paste, followed by patterning. The method includes receiving vector values for an interrupt; determining if an interrupt request is pending; comparing the received vector value with a vector value of the pending interrupt; and replacing a previous vector value with the received vector value if the received vector value has higher priority. The electric signal as a picture signal is supplied to an amplifying circuit. One of the complementary transistors in each pair has a gate coupled to the first and second differential output terminals, respectively.
