Problems solved by technology

Moreover, since this method requires a multiplier for multiplying the current value and the voltage value to calculate the power value, and as Figure 5 As in the shown method, the amount of discharge sustaining voltage applied to the plasma display panel drive unit 60 is controlled based on the result of this calculation, so the characteristics of high-speed response are degraded, and a separate complicated hardware is required.

Abstract

A plasma display apparatus with low power consumption and high speed response is disclosed. The plasma display apparatus includes: a plasma display panel driven by discharge sustain voltage in the form of pulses; an analog-digital converter digitizing image signal inputted from the external; a plasma display panel drive unit converting the digitized image signal into scanning pulses and data pulses driving the plasma display panel and outputting these pulses to the plasma display panel; a power supply unit supplying the discharge sustain voltage to the plasma display panel drive unit; and a controlling unit adjusting the output gain of the analog-digital converter in response to the variation of the output voltage of the power supply unit. With this plasma display apparatus, it is possible to quickly respond and reduce the power consumption occurring when the plasma display panel displays the high luminance of image signal.

Description

technical field [0001] The invention mainly relates to a plasma display and a method, in particular to a plasma display with low power consumption and high response speed. Background technique [0002] A plasma display is a display that restores image data by arranging a plurality of discharge cells (display cells) in a matrix and selectively making these discharge cells emit light. Each discharge cell constituting this plasma display requires a discharge sustaining voltage to maintain the discharge. Thus, each discharge element constituting the plasma display is provided with a high discharge sustaining voltage, thus resulting in higher power consumption compared to other types of displays (eg, cathode ray tubes, liquid crystal displays). [0003] figure 1 is a vertical sectional view of one discharge element constituting the plasma display. [0004] The discharge element shown is an AC discharge element having two opposite glass substrates 10 and 11 , the upper substrat...
