General Description
* Description
LTM240M2-L01 is a color active matrix TFT (Thin Film Transistor) liquid crystal display
(LCD) that uses amorphous silicon TFTs as switching devices. This model is composed of
a TFT LCD panel, a driver circuit and a back-light system. The resolution of a 24.0" contains
1920 x 1200 pixels and can display up to 16.7 million colors with wide viewing angles of
89° or higher in all directions.(Vertical viewing angle : 178°, Horizontal viewing angle : 178°)
* Features
- High contrast ratio, high aperture structure
- S-PVA (Super Patterned Vertical Alignment) mode
- Wide viewing angle
- High speed response
- WUXGA (1920 x 1200 pixels) resolution
- Low power consumption
- U-type 6 CCFTs (Cold Cathode Fluorescent Tube)
- DE (Data Enable) mode
- LVDS (Low Voltage Differential Signaling) interface (2pixel/clock)
- Pb-free configuration
* Applications
Workstation & desktop monitors
Display terminals for AV application products
Monitors for industrial machine and medical appliances
* If the module is used to other applications besides the above, please contact SEC
in advance.

Note (1) Test Equipment Setup
The measurement should be executed in a stable, windless and dark room betwee n
30min and 40min after lighting the back-light at the given temperature for stabilization
of the back-light. This should be measured in the center of screen.
Single lamp current : 6.0mA ( Refer to the note(1) in the page 12 for more information.)
