2.3 TECHNICAL INFORMATION
2.3.1 PDP STRUCTURE AND CHARACTERISTIC
This unit uses the flat type panel PDP (Plasma Display Panel), instead of the conventional CRT (Cathode Ray Tube),
as a display unit.
2.3.1.1 PIXEL (CELL) ARRAY
PDP is constructed by sealing the xenon, which emits neon and ultraviolet rays for discharging purpose, in between the electrodes
lay on the front glass substrate and rear glass substrate.
One pixel is composed of 3 RGB cells, with cell pitch of 0.365mm (1 pixel 1.095mm) [42V MODEL] / 0.307 mm (1 plxel 0.921 mm)
[35V MODEL] horizontally and 1.110mm [42V MODEL] / 0.921 mm [35V MODEL] vertically.
The cell is arrayed in each RGB color as shown in Fig. 1. One pixel is formed by interlacing each RGB color cell.
One cell size is 0.365mm [42V MODEL] / 0.307 mm [35V MODEL] horizontally and 1.110mm [42V MODEL] / 0.921 mm [35V MODEL]
vertically.

2.3.1.2 PIXEL DEFECTS
Though PDP is made by means of ultra precise technology, there are cases whereby not all pixels (cell) will function properly. In
some cases, there may be defective pixels that do not light at all or the ones that always light on.
There are 3 types of Pixel defects, [Bright Dot Defects], [Dark Dot Defects] and [Flicker Dot Defects], as defined respectively in the
following:
(1) Bright Dot Defects
Bright dot defect is a pixel cell that lights though it should not light.
The presence of bright dot defects can be confirmed by inputting a full black signal (pattern).
(2) Dark Dot Defects
Dark dot defect is a pixel cell that does not light, though it should light.
The presence of dark dot defects can be confirmed by inputting a 100% full white signal (pattern).
(3) Flicker Dot Defects
Flicker dot defect is a pixel cell that blinks though it should light or not light.
The presence of flicher dot defects can be confirmed by inputting a full black signal (pattern).
