Control method for a display screen with gradation display and display device for carrying out the same

摘要

The display is controlled by placing each display cell in the 'dark' state or the 'bright' state for a succession of sub-intervals (S1 to S8) determined by the level of luminance required for each cell. The sub-intervals vary, depending on the luminance required. The sub-intervals lie within a given cycle time (P1). In addition, for the rows controlling the cells, the order of the distribution of the sub-periods is adjusted to reduce the amplitude of variations of charge (Q1, Q2) applied to the controller.
