Screen Burning - Pioneer PDP-507CMX Technical Manual

5.6 Screen Burning

When the same image is reproduced for a long period (still image, telop, etc.), the image is burned into to screen. It may
be difficult to remove this image. Burning should be managed by making necessary changes in the video software,
projection method, system configuration etc.
This display has a function that reduces this kind of burning.
[Example of still screens]
1. When displaying a PC screen
• Examples: Power Point, Excel, Word etc.
2. When displaying a monitor camera image
• Examples: images from an outdoor or in-store monitor camera
3. When the same image is displayed repeatedly
• Exhibit explanation video in an art gallery or museum
4. Images with permanent superimposed letters
• Visual information displayed by games, on karaoke screens, or at public facilities
5. Image with lines permanently
• Facility guidance images etc.
6. Image with a remaining peripheral mask
• 4:3 aspect, squeeze contents etc.
The above are typical examples of contents that easily cause burning.

1 ENERGY SAVE setting (Refer to section 5.3.4, "Adjustment and setting in the Menu Mode 4) Energy Saving
Setting" (pg. 178) and 5.3.7, "Adjustment and setting in the Menu Mode 12) Energy Saving Setting" (pg. 203).)
The screen brightness is controlled according to the input signal and by the brightness of the room.

and 5.3.7, "Adjustment and setting in the Menu Mode 15) Orbiter Setting" (pg. 206).)
This function gradually and randomly moves the image position vertically and/or horizontally after a set amount of
time. Or the edges of the images are restricted by setting soft focus in order to soften images edges.
7 Integrator Mode
1 SCREEN MASK Setting (Refer to section 5.4.3, "Adjustment and setting in the Integrator Mode 9) SCREEN
MASK Setting" (pg. 225).)
An inverse or full mask signal appears on the screen.
When a full mask is prepared beforehand, it becomes more difficult for the screen to become burned.
Using an inverse signal may be an emergency measure when the screen is burned from displaying a still image.
However, completely removing the burn is not possible.
2 SIDE MASK Setting (Refer to section 5.4.3, "Adjustment and setting in the Integrator Mode 10) SIDE MASK
Setting" (pg. 226).)
This setting adjusts the method of displaying the SIDE MASK signal and adjusts the signal level of the SIDE
MASK signal.

1 PROGRAM TIMER Setting (Refer to section 5.3.4, "Adjustment and setting in the Menu Mode 6) Program/Repeat
Timer Setting" (pg. 180) and 5.3.7, "Adjustment and setting in the Menu Mode 14) Program/Repeat Timer Setting"
(pg. 205), "5.4.3, "Adjustment and setting in the Integrator Mode 8) Program Timer Setting" (pg. 223).)
