Abstract:
1. A display system comprising: a plurality of pixels, each of said plurality of pixels comprising at least a transistor and an EL (electro-luminescent) element having a first electrode and a second electrode; a sensor for obtaining an information signal of an environment; a CPU (central processing unit) for converting said information signal of the environment supplied from said sensor into a correction signal; an EL driving power source; and a voltage changer connected to receive the correction signal and an output of the EL driving power source, and configured to produce an output potential that varies based on the correction signal, wherein the output potential of the voltage changer is electrically connected to the second electrode of the EL element via a switch, wherein the first electrode of the EL element is electrically connected to a power supply line via the transistor of the pixel including the EL element, and wherein the switch is provided external to the pixels.
