ABOUT LCD PANEL
Common phenomena of LCD Panel
The following are the common phenomena when operating LCD Panel due to its structural reason.
Please note that they are not malfunctions.
● Defective Spots on Panel
The LCD panel is manufactured with high-precision technology. However, there might be some spots that are not emitted,
brighter than the others, or in different colors, etc.
● Surface on Panel
The LCD panel displays images by blinking the fluorescent lamps internally. This could raise the temperature of the
display surface.
In addition, do not impact strongly on the surface of the panel because LCD panel is made with fine processing glass.
● Residual image
When a still image or menu is displayed on the screen for a short time (about a minute) and then switches to another
image, it may leave an “after-image” on the screen.
The residual image will disappear on its own.
● The Usage under the Low Temperature Environment
Because of the structural characteristics of the LCD panel, the response speed of the LCD panel becomes slower when
the ambient temperature around the television becomes too low. In some cases, it may cause the residual image.
The residual image will disappear on its own as the temperature goes up and back to normal.
