3. OVERVIEW
is LCD Module is a display unit that uses a liquid crystal panel with a TFT active
Th
matrix method with a display capacity of 1024x3(RGB)x768 dot and screen size of 38cm
(15.0 inch). This LCD module corresponds to the LVDS 1ch interface and can display 260
thousand colors. In addition, this LCD module operates under a non-interlace mode. It has
a backlight of CCFL that is built in and supplies more electric power than the exclusive
inverter places externally. The power supply of this LCD module is +3.3V DC voltage.
C C
4. CONFIGURATION
This LCD module consists of a color TFT LCD panel and a bezel where the panel driver IC
is mounted into the printed substrate, a cold-cathode florescent tube backlight, and a LVDS
interface PBC. These ar e all combined into one str ucture.
The inverter that supplies electric power to the backlight is configured separately from the
D
LCD module.
Figure 4-1 shows a block diagram of this LCD module.

*2) The value is measured 15-20 minutes after the light on.
*3) The power supply condition is VCC=3.3V,fL=50kHz,If=6mA when the optical
specification is mea sured.
