Patent ID: 7202842

Claim:
A display apparatus comprising: a display unit including a plurality of display elements arranged in a matrix; a drive voltage generating circuit-for generating a drive voltage for driving said plurality of display elements; a dataline drive circuit for generating a signal voltage according to display data, said signal voltage being for controlling the amount of current in each display element; a scanline drive circuit for selecting one or more of said plurality of display elements which is to be applied said signal voltage; a control circuit for controlling a light emission time period in one frame period of each display element according to a distance measured along a supply line on which said drive voltage is supplied from said drive voltage generating circuit to said each display element; wherein each display element comprises an emission element, capacitance element for storing charge corresponding to said signal voltage when said display element is selected by said scanline drive circuit, a drive element for flow through said emission element current according to said charge in said capacitance element, and switch element coupled between said emission element and said drive element, and wherein said switch element switches flowing or not through said emission element said current based on a control signal according to said distance to control said light emission time period in one frame period.
