LTI320W2-L14 is a color active matrix liquid crystal display (LCD) that uses amorphous
silicon TFT(Thin Film Transistor) as switching components. This model is composed of a
TFT LCD panel, a driver circuit and a back light unit. The resolution of a 32.0“ is
1366 x 768 and this model can display up to 16.7 million colors with wide viewing angle of
89°or higher in all directions. This panel is intended to support applications to provide a
excellent performance for Flat Panel Display such as Home-alone Multimedia TFT-LCD
TV, Display terminals for AV application products, and High Definition TV (HDTV).

2. Application information for I.D. (Information Display)
- Generally large-sized LCD modules are designed for TV applications. Accordingly, a long-term
display like in PID application, can cause uneven display including image retention. To optimize
module's lifetime and function, several operating usages are required.
1. Normal operating condition
- Temperature: 20 ±15℃
- Humidity: 65 ±20 %
- Display pattern: dynamic pattern
Note) Long-term static display can cause image retention.
2. Operating usages under abnormal condition1)
a. Ambient condition
- Well-ventilated place is recommended to set up ID system.
b. Power and screen save
- Periodical power-off or screen save2) is needed after long-term display.
3. Operating usages to protect against image retention due to long-term static display
a. Suitable operating time: under 18 hours a day.
b. Static information display recommended to use with moving image.
- Cycling display between 5 minutes' information display and 10 seconds' moving image.
c. Background and character (image) color change
- Use different colors for background and character, respectively.
- Change colors themselves periodically.
d. Avoid combination of background and character with large different luminance.
1) Abnormal condition just means conditions except normal condition.
2) Black image or moving image is strongly recommended as a screen save.
4. Lifetime in this spec. is guaranteed only when ID is used according to operating usages.

3. Optical Characteristics
The optical characteristics should be measured in a dark room or equivalent.

The measurement should be executed in a stable, windless and dark room between
40min and 60min after lighting the back light at the given temperature for stabilization
of the back light. This should be measured in the center of screen.
