doc . no LTA230W1-L02 rev. no. 0.0-041028 page /31 product information (2) lamp frequency may produce interference with horizontal synchronous frequency and this may cause line flow on the display. (3) life time (hr) of a lamp is defined as the time in which it continues to operate under the condition of ta = 252c and il = 7.0marms(max) for a lamp until the brightness becomes 50% or lower than it's original value. (4) if an inverter has shutdown function it should keep its output for more than 1 second even if the lamp connector open. otherwise the lamps may not to be turned on. www.datasheet.net/ datasheet pdf - http://www..co.kr/

(1)the supply voltage of the external system for the module input should be the same as the definition of vdd. (2) 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 become abnormal screen. (3) in case of vdd = off level, please keep the level of input signals on the low or keep a high impedance. (4) t4 should be measured after the module has been fully discharged between power off and on period. (5) interface signal shall not be kept at high impedance when the power is on. 0 doc . no LTA230W1-L02 rev. no. 0.0-041028 page /31 product information 7. outline dimension(front view) www.datasheet.net/ datasheet pdf - http://www..co.kr/

(b) refrain from strong mechanical shock and / or any force to the module. in addition to damage, this may cause improper operation or damage to the module and ccfl back-light. (c) note that polarizers are very fragile and can be easily damaged. do not press or scratch the surface harder than a hb pencil lead. (d) wipe off water droplets or oil immediately. if you leave the droplets for a long time, staining and discoloration may occur. (e) if the surface of the polarizer is dirty, clean it using absorbent cotton or soft cloth. (f) the desirable cleaners are water, ipa(isopropyl alcohol) or hexane. do not use ketone type materials (ex. acetone), ethyl alcohol, t oluene, ethyl acid or methyl chloride. it may cause permanent polarizer da mage due to the chemical reaction. (g) if the liquid crystal material leaks from the panel, it should be kept away from the eyes and mouth. in case of contact with skin or clothes, thoroughly wash it away with soap and water. (h) protect the module from static electricity. it may cause damage to the c-mos gate array ic. (i) use finger-stalls with soft gloves to keep display clean during the incoming inspection and the assembly process. (j) do not disassemble the module. (k) do not pull or fold the lamp wire. (l) do not adjust the variable resistor located on the back side. (m) i/f connector pins should not be touched directly with bare hands. www.datasheet.net/ datasheet pdf - http://www..co.kr/

(b) do not store the tft-lcd module in direct sunlight. the module shall be stored in a dark place. prolonged exposure to sunlight or fluorescent light during the storage will damage the module. 10.3 operation (a) do not connect or disconnect the module in the ? power on ? condition. (b) power supply should always be turned on/off by following item 6.3 ? power on/off sequence ? . (c) the module has high frequency circuits. sufficient suppression to the electromagnetic interference shall be done by system manuf acturers. 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 at the minimum length possible to be connected directly. the longer cable between the back-light and the inverter may cause lower luminance of lamp(ccft) and may require higher startup voltage(vs). operation condition guide (a) the lcd product should to be operated under normal conditions. normal condition is defined as below; -temperature :20 ? 15 ? - humidity : 65 ? 20% - 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. www.datasheet.net/ datasheet pdf - http://www..co.kr/
doc . no LTA230W1-L02 rev. no. 0.0-041028 page /31 product information 10.4 others (a) use ultra-violet light filters if outdoor operation is necessary. (b) avoid water condensation. moisture may penetrate sensitive electrical connections resulting in improper operation. (c) do not exceed the absolute maximum rating values. (supply voltage variation, input voltage variation, variation in part contents and environmental temperature, etc..) otherwise, the module may be damaged. (d) if the module displays the same pattern continuously for a long period of time, it can result in the situation where the image t sticks u (remains) on the screen. we recommend that you should discuss sec when you want the module to be operated in displaying the same pattern for a long time. (e) the module has sensitive pcb circuitry on the back side and should be handled carefully in order prevent stress and possible failure. www.datasheet.net/ datasheet pdf - http://www..co.kr/
