Problems solved by technology

[0008] Because the voltage is supplied to many electrodes at the same time, the above addressing method produces EMI, and because the discharge delays of the discharge cells representing red, green and blue are different, the discharge cells are not discharged at the same time, therefore, the red, green and blue light are not simultaneously emitted so that it is difficult to display natural colors on the pixel

Embodiment Construction

[0035] figure 1 is a view of an electrode arrangement diagram of a PDP.

[0036] Such as figure 1 As shown, the electrodes of the PDP are in the form of an m×n matrix, and specifically, the PDP has address electrodes A1 to Am in the column direction, and scan electrodes (Y electrodes) Y1 to Yn and sustain electrodes ( X electrodes) X1 to Xn. Discharge spaces at points where the A electrodes (A1-Am) cross the X and Y electrodes (X1-Xn, Y1-Yn) form discharge cells 110 .

[0037] The PDP described above is driven according to a reset period, an address period, and a sustain period in time. In the reset period, the discharge cells are reset so that an address operation is stably performed on the discharge cells. In the address period, an address voltage is supplied to a discharge cell to be turned on (that is, an addressed discharge cell) so as to accumulate wall charges on the discharge cell, thereby selecting the discharge cell to be turned on and the discharge cell not to b...

Abstract

In a Plasma Display Device (PDP) and driving method thereof to reduce Electro Magnetic Interference (EMI), address electrodes are divided according to colors controlled by the address electrodes in the address period and voltages are supplied to the electrodes at different times to reduce EMI, and red, green, and blue discharge cells are controlled to concurrently emit light to display natural colors clearly.

Description

technical field [0001] The present invention relates to a plasma display panel (PDP) and a driving method thereof, and particularly to a PDP and a driving method thereof, which discriminate address electrodes by color and differentially start supplying voltages during address periods to reduce Electromagnetic Interference (EMI). Background technique [0002] Recently, flat panel displays, such as liquid crystal displays (LCDs), field emission displays (FEDs), and PDPs, have been actively developed. PDP has advantages over other flat panel displays in terms of high brightness, high luminous efficiency and wide viewing angle. Therefore, the PDP has been highly regarded as a substitute for the conventional cathode ray tube for large-screen displays exceeding 40 inches. [0003] Electrodes of the PDP are in a matrix form, and specifically, the PDP has address electrodes in a column direction, and scan electrodes and sustain electrodes in a row direction. Discharge spaces at p...
