- Page 64 OLED Handling of OLED TV 1. Notes of handling the OLED TV The thickness of the OLED TV is much thinner than that of LCD. The minimum thickness of OLED TV is about 7mm. (There is no rear cover at top side.) So the shape of OLED TV(panel) bends or undulates more easily than that of LCD.
- Page 65 Panel Maintenance function-1 OLED 仕様概略 OLED model have Panel Maintenance function to reduce “image retention”. 1. What is Panel Maintenance function? The use of the OLED panel for a long period causes no uniformity of charge in each OLED cell or degeneration of OLED light emission elements, and these are possible causes of "image retention“.
- Page 66 Panel Maintenance function-2 OLED 仕様概略 3. How to activate the Panel Maintenance function 3-1. Flow of Panel Maintenance-1 mode (It takes about 10 min.): The Panel Maintenance-1 mode is automatically activated when the TV is turned off with remote control after watching TV for 3 hours or more.
- Page 67 Panel Maintenance function-3 OLED 仕様概略 3-2. Flow of Panel Maintenance-2 mode (It takes about 80 min.) : There are 2 flows. One is executing manually from Menu. The other is automatically activated when the TV is turned off with remote control after watching TV for 1500 hours or more. If you have customer complaints for “image retention”, please activate the Panel Maintenance in Menu.
