23 Electronic Display Industrial Research Association of Korea
【 제 5회 평판디스플레이 표준화기반구축사업 워크샵 】 TC110/WG4 Meeting (Boston)  Gray scale - PDP module must emit light proportional to input gray scale - For different input grays, if the output of a module is the same or reversed, picture quality will be degraded. - So, the characteristics of input gray to output luminance should be checked.  To evaluate performance and compare with other modules, the standard method for measuring gray scale quality is necessary.  Image streaking - Generally, PDP module shows different luminance when pixels with the same gray level have different line load. The same gray level brighter - For the image streaking, any standard measuring method has not been made yet. - This phenomenon may distort picture information.

【 제 5회 평판디스플레이 표준화기반구축사업 워크샵 】 TC110/WG4 Meeting (Boston)  Flicker - Flicker is one of the most important factors in evaluating picture quality, particularly in 50Hz broadcasting area. - As the screen size of display is larger, the flicker becomes more serious. - PDP is supplied as a display with large screen size.  So, the standard measuring method must be made as soon as possible.  Acoustic noise - In PDP module, there are various acoustic noise sources : (1) generated between the front and the rear glasses. (2) induced by coils for energy recovery. (3) induced by transformers for AC to DC converter. and so on. - The acoustic noise may annoy people, especially in a silent night. - The amount of acoustic noise can be varied depending on measuring position and distance.  So, we need the standard measuring method for the acoustic noise.
