DRIVING METHOD FOR DISPLAY PANEL, AND PANEL DISPLAY DEVICE

Japanese Patent JP3112820

B2

PROBLEM TO BE SOLVED: To make frecise gradational display irrelevantly to the difference in display load between subframes by weighting a period of display light emission, subframe by subframe, and making it different for the gradational display.
SOLUTION: This device is provided with a data counter 112 as a display load calculating means which calculates the display load of the entire display screen for each subframe and correction period calculating means 110 and 111 which calculates a correction period for the light emission period of a display light emitting means, subframe by subframe, according to the display load of each subframe calculated by the data counter 112 so that the lightness of a display cell by each subframe has a specific ratio between subframes. The display light emitting means emits light for the correction period. The counter 112 is provided with counters as many as the subframes and each counter counts cells where maintained discharging is performed, subframe by subframe, converts the counted value into bit data representing the display load with the ratio to the total number of cells of the entire screen, and outputs the bit data.
