1. Application Object
This standard is applied to the PDP42V6#### PDP Module which is manufactured by the manufacturing
team of PDP promotion department or elsewhere.
2. Notes
(1) Without any special specification, the Module should be at the condition of preliminaries more than 10minutes
before adjusting.
- Service signal: 100% Full White signal
- Service DC voltage: Vcc: 5V, Va: 65V, Vs: 185V
- DC/DC Pack voltage: Vsetup: 200V, Vscw: 115V, -Vy: -75V
- Preliminaries environment: Temp (25
±
5°C), Relative humidity (65
±
10%)
(2) Module should get the Aging for the equilibrium after finish the assembling. Aging condition is shown below.
- Service signal: 100% Full White, Red, Green, Blue pattern signal (Service time of each pattern: within
5minutes/cycle)
- Service DC voltage: Match the voltage with the set up voltage in the first adjustment.
- Aging time: More than 4Hrs
- Aging environment: Temp (60
±
2°C), Relative humidity- Less than 75%
(3) Module adjustment should be followed by below sequence.
- Setting up the initial voltage and adjusting the voltage wave form of Vsetup
- Measuring the Margin of Vs voltage and deciding the voltage
- Adjusting and checking the voltage of DC/DC pack (Vsetup, Vscw, -Vy)
- Adjusting the voltage wave form of Vset-down
- Measuring the Margin of Vset-up voltage and deciding the voltage
- Adjusting the wave form of final voltage
But, these items above can be changed by the consideration of mass production. (When changing the se-
quence, there should be an agreement of the Module development 2Gr./ QA Gr./ Manufacturing Gr.)
(4) Without any special specification, you should adjust the Module in the environment of Temp (25
±
5°C) and Rel-
ative humidity (65
±
10%).
Caution) If you let the still image more than 10 minutes (especially The Digital pattern or Cross Hatch Pat-
tern which has clear gradation), after image can be presented in the black level part of screen.
