ePanel-C3
Version 1.04
Display Configuration
The ePanel C3 offers three display output options: analog CRT, LVDS Interface for LCD panels and an analog
TVOut output. However, only two output options can be used at a time. Example: the use of an LCD panel and
the TVOut output inevitably requires the analog CRT output to be disabled.
OnChip VGA Frame Buffer Size
With this option the size of the Frame Buffer can be defined. By default, this is 16 MByte. If the TVIn-Interface
is being used, the Frame Buffer must be increased to 32 MByte.
Boot CRT Screen
Enables or Disables the analog CRT output (Default: Enabled).
Boot LCD Screen
Enables or Disables the LVDS Interface for LCD panels (Default: Disabled). Upon changing to Enabled, the
five following options appear (Software Panel Type to Backlight Brightness).
Software Panel Type
This option represents the available resolutions (e.g. 800x600 or 1024x768 pixels). This selection must match
the resolution of the LCD panel.
LCD Mode
Expanded displays the screen content always at the maximum size (Default), Centered centers the screen
content (e.g. in DOS mode).
LVDS Width
Single defines Single-Clock (Default), Dual defines Dual-Clock. This setting must be made according to the
specifications of the panel datasheet.
LVDS Bit Order
The term Standard defines FPDI and Shifted LDI. Smaller panels of up to XGA resolution work normally with
FPDI, while LDI is commonly used for larger panels. An incorrect setting results in a rough mismatch of colors.
Backlight Brightness
The Brightness value (0 – 255) can be changed using the <+> und <-> keys. A higher value means higher
voltage. The output is immediate, i.e. you can already see the Brightness adjustments during setup.
