Notes 1. Ambient temperature condition (Ta = 25 2 °C )
2. Temperature and relative humidity range are shown in the figure below.
Wet bulb temperature should be Max 39°C, and no condensation of water.
3. Gravity mura can be guaranteed below 40°C condition.
4. The maximum operating temperatures is based on the test condition that the surface temperature
of display area is less than or equal to 68°C with LCD module alone in a temperature controlled chamber.
Thermal management should be considered in final product design to prevent the surface temperature of
display area from being over 68℃. The range of operating temperature may be degraded in case of
improper thermal management in final product design.

※ Please pay attention to the followings when you set Spread Spectrum Rate(SSR) and Modulation
Frequency(FMOD)
1. Please set proper Spread Spectrum Rate(SSR) and Modulation Frequency (FMOD) of TV system
LVDS output.
2. Please check FOS after you set Spread Spectrum Rate(SSR) and Modulation Frequency(FMOD)
to avoid abnormal display. Especially, harmonic noise can appear when you use Spread Spectrum
under FMOD 30 KHz.
