Abstract
A plasma display panel, a white linearity control device and a control method thereof. The white linearity control method includes calculating a load ratio of an image signal, determining an automatic power control level corresponding to the load ratio, and calculating first correction data corresponding to the automatic power control level. In addition, the method includes discriminating vertical and horizontal positions of the image signal, and obtaining a white linearity value for a corresponding region from two white linearity values defining a period in which the discriminated positions are included through interpolation, and producing second correction data by multiplying the first correction data by the obtained white linearity value.
