Optimum Picture Quality and Afterimage Burn-in Prevention

Optimum Picture Quality

•• Due to the nature of the manufacturing of this product, approximately 1 pixel per million (1ppm) may be brighter or darker on the panel. This does not affect product performance.

––The number of sub-pixels by panel type: 24,883,200

•• Leaving the screen fixed on a stationary image for an extended period of time may cause afterimage burn-in or defective pixels.

––Activate power-saving mode or a dynamic screen saver if you will not be using the product for an extended period of time.

Prevention of Afterimage Burn-in

What is afterimage burn-in?

Afterimage burn-in should not occur when the LCD panel is operating normally. Normal operation refers to a continuously changing video pattern. If the LCD panel displays a fixed pattern for an extended period of time, a slight voltage difference may occur between the electrodes in pixels that control the liquid crystals.

Such a voltage difference between electrodes increases with time and makes the liquid crystals thinner. When this occurs, a previous image can remain on the screen when the pattern changes. To prevent this, the accumulated voltage difference should be reduced.

――Afterimage burn-in should not occur when an LCD panel is operating in proper conditions.
