ABSTRACT:
In a light emission display drive method, a driver capable of performing control of three or more levels in the output brightness of each light emission element is provided and when the intermediate level is represented, a ΔΣ modulator controls the distribution of the occurrence probability of each level, whereby multi-level gradation representation is conducted. At this time, one channel of ΔΣ modulator is provided and a quantizer with “N-1”-value threshold, N-value output is used and the driver is controlled in response to output of the quantizer or separate ΔΣ modulators are provided for weight multiple outputs and the input values to represent gradation are distributed through a distributor.
