User Manual
21 / 35
The analog signal level is derived either from the inverted or from the non-inverted PWM
signal. (The PWM signal is integrated and then limited to the selected peak voltage of the
backlight inverter).
The peak level of the brightness signal can be selected with a jumper on X803 to be either
3.3V or 5V. The maximum brightness (with 0V or with 3.3V/5V) will depend on the Inverter or
LED backlight type used.
See section 3.3.4 for LVDS Panel Jumper settings.

LVDS EEPROM
To store configuration data for the display, a serial EEPROM is connected to the LVDS I2C
bus -signals LVDS_I2C_CK and LVDS_I2C_DAT.
To avoid conflicts with a configuration EEPROM on the connected display, this EEPROM can
be mapped to an unused address space. The address can be configured with a jumper on
See section 3.3.4 for Jumper settings.
LVDS panel jumper settings (X803, X804, X805)
The settings for the LCD panel are configurable using the row of jumpers
. In the following we use the name
for this row and the pin numbers are increased
seamless between this parts as shown in Figure 5:

3.3.4.1 Display power jumper
The power supply voltage for the LCD panel (NOT the backlight) is selected with a jumper on
the jumper block
. The software control of the LCD panel enable signal can be
bypassed by inserting a jumper on pins 1-2.
