Lead in the solder used in this product
is a known reproductive toxicant which
may cause birth defects or other reproductive
harm. (California Health and Safety Code
Section 25249.5).
When servicing this or handling circuit
boards and other components which
contain solder, avoid unprotected skin
contact with the solder. Also, when
soldering do not inhale any smoke or
fumes produced.
This technical training guide will address
the disassembly and adjustments of the
Pioneer PDP-503CMX Plasma Display.
This guide was designed as a servicing aid
and is not intended to replace the service
manual. The student should have the
appropriate service manual on hand when
when using this guide. Data in the service
manual for this unit contains specific
information on safety, parts and adjustments.
Safety information
Important safety data for this Pioneer model
is contained in the service manual. Before
returning the unit to the customer, complete
all product safety obligations and tests.
Technicians who bypass safety features or
fail to carry out safety checks may expose
themselves and others to possible injury,
and may be liable for any resulting damages.

DVI-D interface for PDA-5002
There are two types of DVI interface; DVI-D and DVD-I. PDA-5002 has DVI-D input. Which
means this terminal can only accept Digital RGB signal.
Also the cable must be DVI-D cable.
DVI-I cable can not be used for PDA-5002.

Deep Waffle Rib Structure: realises even higher light emission
efficiency
For the PDP-503, Pioneer’s further improved this technology
by making each individual cell deeper.
Deep Waffle Rib Structure
(Deep Encased Cell Structure)
The new cell structure has a greater light emission area, so this results in
even higher light emission efficiency—50% higher than our previous model .
(PDP-502)

[D] Sustaining discharge is made by a pulse of voltage on sustain electrodes. It
generates UV light, which makes phosphor radiate visible light emission.
[E] The electric at electrodes remains so that continuous pulses of AC voltage
can make another light-emitting discharge
PDP basic principles
The PDP screen is 2 glass panels with pixels sandwiched. The pixels consist of tiny
cells with electrodes on the top and bottom. Inert gas (Xenon+Neon) is trapped
between 2 glasses, separated by a gap of just 100-200 microns wide. UV light is
generated by discharging the gas using electrodes. Red, green and blue phosphors
absorb these UV discharges and reradiate the energy as visible light to produce the
colors that appear on the screen.
[F] Address discharge selects the cells
required for emission by clearing the
electric charge from unnecessary cells
with comparatively small voltage

[B-C] Initialization discharge
(Reset) charges the electric at
+/- electrodes, activating

Output/ Brightness
•Linear shaped characteristics of brightness level against input signal of conventional PDP is
poor at gradation in low brightness range
•Allocating comparatively more steps in low range, Characteristics of 503 has a gamma curve
similar to analog CRT, which doesn’t require the artificial process for offsetting gamma curve
of input signal in video processing

CLEAR driving method: the way to increase gradations
Each field (1/60 sec) can have 12 steps. (in case of NTSC)
With using 2 neighboring fields, different grayscales are
assigned. By combining these 2 fields, grayscales in-
between can be generated. As a result of it, another 12
steps can be implemented to get 2 times as many
grayscales as that of 1 field.

Gradation Reproduction in Low Brightness Range
Pioneer’s CLEAR* driving technology has succeeded in eliminating
false contour of poor gradation areas. Details in shadow that were
previously obscured in conventional PDP can now be seen.
(*CLEAR: high-Contrast & Low Energy Address & Reduction of false contour
sequence. We alternatively call it “Continuous Emission Display Technology”)
Pioneer CLEAR drive
Conventional PDPs exhibit rough gradations in the low brightness
range, so image quality in dark areas is inferior. Pioneer’s gradation
slope is much smoother.
Even with dark images, detailed patterns are faithfully reproduced.

Reset
•Only one reset discharge per field
•Continuous light Emission of the needed number of pulse
•No random light emission = No more random gaps without emission
Results :
•Higher Contrast (Lowest brightness less than 1cd/m2)
•Less Addressing power consumption: 1/3 vs 501
•No Dynamic False contour
