PDP (PLASMA DISPLAY PANEL) DESCRIPTION
!
CAUTION
Although a PDP is made with highly advanced precis ion, this does not neces sarily mean all of the cells operate correctly.
The PDP inevitably includes c ell that do not light or light constantly.
If the specifications (PDP performance) are unclear at the time of shipment, an adequate description cannot be c onveyed to the customer.
In event of inquiries from c ustomers regarding PDP performance, chec k the following s pecifications in order to offer a suitable reply.

CELL ARRANGEMENT
The PDP is c ons tructed of front and rear glass substrates provided with res pec tive discharge elec trodes. Between thes e, neon for
discharging and xenon for generating ultraviolet rays are enclos ed.
One picture element (pix el) is composed of Red, Green and Blue (RGB) cells. The cell pitch is 0.36mm horizontal (1.08mm per pixel) by
1.08mm vertical.
