3. PRODUCT NAME AND MODEL NUMBER
x Product name : 42 inch Full Color Plasma Display Module
(abbreviation : PDP Module)
x Model number : S42AX-YD13(M3) (Project name : U2P)
4. FUNCTION OUTLINE
x The plasma display module has an APC(Automatic Power Control) function which
restricts power consumption within the certain value with regard to each display load
ratio.
x The plasma display module is operated by following digital video signals; Vertical
synchronous signal, Horizontal synchronous signal, Enable signal and 8~12bit data
signals of each R, G and B color. All signals are based on LVDS level.
x The plasma display module is operated at 50Hz60Hz frame rate. An external frame rate
conversion is required in order to display the other formats.
x The plasma display module requires several types of input power voltages ; voltage for
logic IC, voltage for Gate Driver, voltage for Sustain and voltage for Address.
x The plasma display module is operated at progressive signal only.
An external progressive scan conversion is required in order to display the other formats.

6.5 Display Cell Defect Specification
In some cases, a panel may have defective cells that cannot be controlled.
These defective cells can be categorized into three types;
(1) Non-lighting cell defect : defect in which the cell is always off
(2) Non-extinguishing cell defect : defect in which the cell is always on.
(3) Flickering cell defect : defect in which the cell is flickering.
(4) High intensity cell defect : defect in which the cell is brighter than other cells
(5) Test Pattern : Full White, Full Red, Full Green and Full Blue with 1024 gray level.
The display cell defect specifications define the allowed limits for display cell defects
and
are used as the criteria in determining whether a panel should be shipped.

6.6 Uniformity Specifications
The color-PDP uses ultraviolet light produced by gas discharge to illuminate phosphor.
Uneven phosphor coating and inconsistent discharge characteristics cause slight difference
in brightness among the sections in a panel.

6.7 Power consumption
6.7.1 APC (Automatic Power Control) Function
The PDP has an APC (Automatic Power Control) function for the panel driver power source.
When the total display load ratio exceeds approximately 10%, total power consumption is
limited within a specified level (=Lower Power Limit) by APC function.
The operation behavior of APC function is called as SLOW-APC. When the display loadratio changes from low to high value, the power-consumption rises instantly to “Upper
Power Limit” and gradually decreases until it reaches to the “Lower Power Limit.”
[Note] Number of steps may Power vary as a function of the load ratio.

6.7.2 Brightness and Power Mode Control
This PDP module offsers two methods for Brightness and Power mode control.
One is APCO(APC Offset) for Peak-Brightness control, and the others are PUG and
PLG
for power mode control. APCO, PUG and PLG are registers controllable through I2C
communication from image B’d. For a detailed address and data bits of these registers ,
refer to the Chapter 11. Address Map.
(1) Peak-Brightness Control( APCO)
- controls the max.sustain number
- APCO variable range : 0010h~01FFh (cf. 00C8h~01F4h @3D Mode)

(5) SAPC_Timer
The module is equipped with the APC Timer function to reduce the amount of image
retention. If the input image is not varying for at least one minutes, the fuction starts to
operate and reduce the intial APC level one step down to a predefined target level in
every three seconds. The fuction is immediately turned off when the input image starts
varying.
