NoLTM190M2-L31MODEL Approval SpecificationApproval Specification (2) Lamp frequency which may produce interference with horizontal synchronous frequency may cause line flow on the display. Therefore lamp frequency should be detached from the horizontal synchronous frequency and its harmonics as far as possible in order to avoid interference. (3) Life time (Hr) is defined as the time when brightness of a lamp unit itself becomes 50% or less than its original value at the condition of Ta = 252C and IL = 6.5mArms (4) Designing a system inverter intended to have better display performance, power efficiency and lamp reliability. They would help increase the lamp lifetime and reduce leakage current. a. The measurement should be done at typical lamp current. b. The asymmetry rate of the inverter waveform should be less than 10%. c. The distortion rate of the waveform should be ²2 with 10% tolerance. - Inverter output waveform had better be more similar to ideal sine wave. ||II Irms p- p− ×100 Asymmetry rate Distortion rate (5) If an inverter has shutdown function, it should keep its output for over 1 second even if the lamp connector is open.

29/39Page05-000-G-061128Doc. NoLTM190M2-L31MODEL Approval SpecificationApproval Specification To prevent a latch-up or DC operation of the LCD Module, the power on/off sequence should be as the diagram below. T1 : VDD rising time from 10% to 90% T2 : The time from VDD to valid data at power ON. T3 : The time from valid data off to VDD off at power Off. T4 : VDD off time for Windows restart T5 : The time from valid data to B/L enable at power ON. T6 : The time from valid data off to B/L disable at power Off. The supply voltage of the external system for the Module input should be the same as the definition of VDD. Apply the lamp voltage within the LCD operation range. When the back light turns on before the LCD operation or the LCD turns off before the back light turns off, the display may momentarily show abnormal screen. In case of VDD = off level, please keep the level of input signals low or keep a high impedance. T4 should be measured after the Module has been fully discharged between power off and on period. Interface signal should not be kept at high impedance when the power is on. 300ɫT110msec 0T250msec 0T350msec 1secT4 Back-Light (Recommended) 500msecT5 100msecT6

37/39Page05-000-G-061128Doc. NoLTM190M2-L31MODEL Approval SpecificationApproval Specification (a) When the module is assembled, it should be attached to the system firmly using all mounting holes. Be careful not to twist and bend the module. (b) Because the inverter uses high voltages, it should be disconnected from power source before it is assembled or disassembled. (c) Refrain from strong mechanical shock and / or any force to the module. In addition to damage, it may cause improper operation or damage to the module and CCFT back light. (d) Note that polarizer films are very fragile and could be damaged easily. Do not press or scratch the surface harder than a HB pencil lead. (e) Wipe off water droplets or oil immediately. If you leave the droplets for a long time, staining or discoloration may occur. (f) If the surface of the polarizer is dirty, clean it using absorbent cotton or soft cloth. (g) Desirable cleaners are water, IPA (Isopropyl Alcohol) or Hexane. Do not use Ketone type materials (ex. Acetone), Ethyl alcohol, Toluene, Ethyl acid or Methyl chloride. It might cause permanent damage to the polarizer due to chemical reaction. (h) 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 with soap thoroughly. (i) Protect the Module from static, or the CMOS Gate Array IC would be damaged. (j) Use finger-stalls with soft gloves in order to keep display clean during the incoming inspection and assembly process. (k) Do not disassemble the Module. (l) Do not pull or fold the lamp wire. (m) Do not adjust the variable resistor located on the Module. (n) Protection film for polarizer on the Module should be slowly peeled off just before use so that the electrostatic charge can be minimized. (o) Pins of I/F connector should not be touched directly with bare hands. 11. General Precautions
38/39Page05-000-G-061128Doc. NoLTM190M2-L31MODEL Approval SpecificationApproval Specification (a) Do not leave the Module in high temperature, and high humidity for a long time. It is highly recommended to store the Module with temperature from 0 to 35 and relative humidity of less than 70%. (b) Do not store the TFT-LCD Module in direct sunlight. (c) The Module should be stored in a dark place. It is prohibited to apply sunlight or fluorescent light in storing. (a) Do not connect or disconnect the Module in the "Power On" condition. (b) Power supply should always be turned on/off by the item 6.3 "Power on/off sequence" (c) Module has high frequency circuits. Sufficient suppression to the electromagnetic interference should be done by system manufacturers. Grounding and shielding methods may be important to minimize the interference. (d) The cable between the back light connector and its inverter power supply should be connected directly with a minimized length. A longer cable between the back light and the inverter may cause lower luminance of lamp(CCFT) and may require higher startup voltage(Vs).
11.4 Operation Condition Guide
(a) The LCD product should be operated under normal conditions. Normal condition is defined as below; - Temperature : 2015 - Humidity : 6520% - Display pattern : continually changing pattern (Not stationary) (b) If the product will be used in extreme conditions such as high temperature, humidity, display patterns or operation time etc.., It is strongly recommended to contact SEC for Application engineering advice. Otherwise, its reliability and function may not be guaranteed. Extreme conditions are commonly found at Airports, Transit Stations, Banks, Stock market, and Controlling systems.

11.5 Others
(a) Ultra-violet ray filter is necessary for outdoor operation. (b) Avoid condensation of water. It may result in improper operation or disconnection of electrode. (c) Do not exceed the absolute maximum rating value. ( supply voltage variation, input voltage variation, variation in part contents and environmental temperature, and so on) Otherwise the Module may be damaged. (d) If the Module keeps displaying the same pattern for a long period of time, the image may be "sticked" to the screen. To avoid image sticking, it is recommended to use a screen saver. (e) This Module has its circuitry PCB's on the rear side and should be handled carefully in order not to be stressed. (f) Please contact SEC in advance when you display the same pattern for a long time.
