Abstract:
A display device has centers of three sub-pixels arranged to form a triangle together and one side of the triangle is orientated in the same direction as a vertical direction of a displayed image. When a black or white vertical line is displayed, image signal data of left and right pixels adjacent to the black or white vertical line are converted into cyan-biased or magenta-biased image signal data, thereby enhancing the visibility and readability of displayed characters.

Abstract:
A plasma display includes a plurality of discharge cells, and is driven with one frame divided into a plurality of subfields having respective weight values. Light emitting cells are selected through address discharge during an address period of each subfield, and sustain discharge is performed on the light emitting cells for a number of times corresponding to a weight value of the corresponding subfield during a sustain period of each subfield to display images. The plasma display provides a sensing period for identifying an external contact with the plasma display prior to the address period in at least one subfield of the plurality of subfields, and discharges the plurality of discharge cells during a sensing period. The plasma display identifies the external contact based on light generated from the discharge cells during the sensing period.
Abstract:
A plasma display panel and a method thereof is described. A frequency of a sustain pulse varies according to a screen load ratio in each subfield or frame. The frequency of the sustain pulse is determined such that power consumption of the plasma display panel, which is a function of the active power and the reactive power of the sustain pulse, is minimized. When the screen load ratio is increased, the frequency of the sustain pulse is increased since the decrease of the active power is increased and the reactive power is maintained.
