Note1. 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 65°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 65℃. The range of operating temperature may degraded in case of
improper thermal management in final product design.

Note 1. The Input of HSYNC & VSYNC signal does not have an effect on normal operation(DE Only Mode).
If you use spread spectrum for EMI, add some additional clock to minimum value for clock margin.
2. The performance of the electro-optical characteristics may be influenced by variance of the vertical
refresh rate and the horizontal frequency.
