CAUSE
Due to the nature of LCD's property, afterimage can occur. Afterimage appears when identical frames / images
are displayed continuously. If displayed for prolonged periods of time this can become permanent.
PREVENTION
When you display a freeze frame for a long time, lower the brightness and contrast (Brightness, 70/ Contrast,
80). Also it can be prevented by using moving frame.
COUNTERMEASURES
Temporary afterimage can be alleviated by displaying white or moving frame about 10 hours. (But, permanent
afterimage cannot be disappeared according to the property of LCD) This method is used to remove temporary
afterimage that may occur after displaying a still frame for a certain time.
It can take several minutes or hours to remove afterimage according to the severity. In
the case that your
cannot avoid displaying identical still image continuously, you can
prevent it by displaying moving image
for 2 or 3 minutes in every hour. As the brightness
of still image and time of display are the cause of afterimage,
you are recommended to
lower the brightness in that case.
