Note 1 : The response time will become lower when operated at low temperature. Note 2 : Background color changes slightly depending on ambient temperature.
Note 3:Define “LED Lifetime”: brightness is decreased to 50% of the initial value. LED Lifetime is restricted under normal condition, ambient temperature = 25℃ and LED
lightbar current = 20 mA. Note 4:If it uses larger LED lightbar voltage/ current more than 20mA, it maybe decreases the LED lifetime.

11.2 RGB INTERFACE CHARACTERISTICS (a) Signal AC Characterics Note 1: Signal rise and fall times are equal or less than 20ns. Note 2: Measuring of input signals are 0.30 x VDDI for low state and 0.7 x VDDI for high state. Note 3: Note5: The frame rate is calculated by using default values. FR=Min. 50Hz, Max. 65Hz
11.3 POWER ON/OFF CHARACTERISTICS Recommended Power On / Off Sequence. The LCD adopts high voltage driver IC, so it could be permanently damaged under a wrong power on/off sequence. The suggested LCD power sequence is below:
13.PRECAUTIONS FOR USE 13.1 SAFETY (1) Do not swallow any liquid crystal, even if there is no proof that liquid crystal is poisonous. (2) If the LCD panel breaks, be careful not to get liquid crystal to touch your skin. (3) If skin is exposed to liquid crystal, wash the area thoroughly with alcohol or soap. 13.2 STORAGE CONDITIONS (1) Store the panel or module in a dark place where the temperature is 23±5°C and the humidity is below 50±20%RH. (2) Store in anti-static electricity container. (3) Store in clean environment, free from dust, active gas, and solvent. (4) Do not place the module near organics solvents or corrosive gases. (5) Do not crush, shake, or jolt the module. 13.3 HANDLING PRECAUTIONS (1) Avoid static electricity which can damage the CMOS LSI. (2) The polarizing plate of the display is very fragile. So, please handle it very carefully. (3) Do not give external shock. (4) Do not apply excessive force on the surface. (5) Do not wipe the polarizing plate with a dry cloth, as it may easily scratch the Surface of plate. (6) Do not use ketonics solvent & Aromatic solvent, use with a soft cloth soaked with a cleaning naphtha solvent. (7) Do not operate it above the absolute maximum rating. (8) Do not remove the panel or frame from the module. (9) When the module is assembled, it should be attached to the system firmly,Be careful not to twist and bend the module. (10) Wipe off water droplets or oil immediately . If you leave the droplets for a long time,staining and discoloration may occur. (11) If the liquid crystal material leaks from the panel,it should be kept away from the eyes or mouth.In case of contact with hands,legs or clothes, it must be washed away thoroughly with soap. 13.4 WARRANTY (1)Acceptance inspection period The period is within one month after the arrival of contracted commodity at the buyer’s factory
site. (2) Applicable warrant period The period is within 12 months since the date of shipping out under normal using and storage
