Abstract
An active-matrix display device employs current-programmed-type pixel circuits and performs the writing data to each of pixels on a line-by-line basis. The active-matrix display device having a matrix of current-programmed-type pixel circuits includes a data line driving circuitformed of m current driving circuits (CD)-to-arranged corresponding to respective data lines-to-. The data line driving circuit (CD)-to-holds image data (luminance data herein) in the form of voltage, and then converts the voltage of the image data into a current signal. The current signal is then fed to the data lines-to-at a time. The image information is thus written on the pixel circuits
