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℃ condition.
4. The maximum operating temperature is based on the test condition that the surface temperature
of display area is less than or equal to 68 ℃ 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
degrade in case of improper thermal management in final product design.

Note 1. All Input levels of LVDS signals are based on the EIA 644 Standard.
2. If tRF isn‟t enough, teff should be meet the range.
3. LVDS Differential Voltage is defined within teff
