Patent ID: 7932878

Claim:
An active matrix-type display apparatus comprising: 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 a latch circuit to store an information, and wherein the column current control circuit compares the stored information in the latch 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; wherein the column current control circuit includes a lookup table for storing a compensation information determined from the newly input information and the information stored in the latch circuit and outputs the converted information such that the compensation information is added to the newly input information; and the operation circuit sets V.sub.n to be V.sub.n=D.sub.n−.alpha. (where, .alpha. is a constant value) if D.sub.n−V.sub.n−1 is equal to or greater than a first setting value, to be V.sub.n=D.sub.n−.beta. (where, .beta. is a constant value) if D.sub.n−V.sub.n−1 is equal to or smaller than a second setting value and to be V.sub.n=D.sub.n if D.sub.n−V.sub.n−1 is smaller than the first setting value and larger than the second setting value, thereby outputting the set V.sub.n, where D.sub.n is the newly input image information, V.sub.n−1 is the converted information stored in the latch circuit and V.sub.n is the converted information output from the operation circuit.
