■ General specifications
2. LCD UNIT
■ Color TFT LCD module LK520D3LZ19
This module is an active matrix, transmission-type, LCD display which
uses the amorphous silicon thin-film transistor (TFT: Thin-Film Transis-
tor) and enables color display.
The circuit is composed of the color TFT - LCD panel, the driver IC, the
The circuit is composed of the color TFT - LCD panel, the driver IC, the
control circuit, the power circuit, the inverter circuit, the backlight unit,
etc. As an interface, the LVDS (Low Voltage Differential Signaling) is
used to supply

1080 dots. This module also includes the DC/AC inverter which is
used to drive the lamp.
The backlight is of direct under system and is composed of 24 CCFT’s
(Cold Cathode Fluorescent Tubes).
• Screen size
: 132.174 cm (52 type) opposing corner
• Drive display area
: 1152.0 mm (H)
×
648.0 mm (V)
• Max. brightness
: 450 cd/m2 (Typ.)
• Backlight life
: 60,000 hour
*
* When the lamp is lighted continuously at Ta=25°C and the center
brightness reaches 50% of the initial value, it is judged as the life is
expired.
