product specification 13 / 14 LH350Q01-A1 liquid crystal display ver 1.0 aug. 20, 2004 7. precautions please pay attention to the following when you use this tft lcd panel. 7-1. mounting precautions 7-2. operating precautions (1) the spike noise causes the mis-operation of cir cuits. it should be lower than following voltage : v= 200mv(over and under shoot voltage) (2) response time depends on the temperature.(in lo wer temperature, it becomes longer.) (3) brightness depends on the temperature. (in lowe r temperature, it becomes lower.) and in lower temperature, response time(required ti me that brightness is stable after turned on) becomes longer. (4) be careful for condensation at sudden temperatu re change. condensation makes damage to polarizer or electrical contacted parts. and after fading condensation, smear or spot will occur. (5) when fixed patterns are displayed for a long ti me, remnant image is likely to occur. (6) the tft-lcd shall be operated within the temper ature limits specified. when you operate the lcd panel at below(beyond) the limit specified, it may cause damage or image degradation. this phenomenon may not recover. 1) when the surface becomes dusty, please wipe gentl y with absorbent cotton or other soft materials. 2) since a module is composed of electronic circuits , it is not strong to electrostatic discharge. make certain that treatment persons are connected to ground through wrist band etc . 3) do not leave at the high temperature and high humi dity in long time. 4) do not leave the tft-lcd panel from direct sunligh t. 5) do not contact with water to avoid metal corrosio n. 6) the tft-lcd panel shall be installed flat, without twisting or bending since a module is composed of electronic circuits, it is not strong to electrostatic discharge. make certain that treatment persons are connected t o ground through wrist band etc. and dont touch interface pin directly. 7-3. electrostatic discharge control www.datasheet.co.kr datasheet pdf - http://www..net/
product specification 14 / 14 LH350Q01-A1 liquid crystal display ver 1.0 aug. 20, 2004 strong light exposure causes degradation of color f ilter. 7-4. precautions for strong light exposure when storing tft-lcd panel as spares for a long tim e, the following precautions are necessary. (1) store them in a dark place. do not expose to su nlight or fluorescent light. keep the temperature between 5 c and 35 c at normal humidity. (2) the tft-lcd glass surface should not come in co ntact with any other object. it is recommended that they be stored in the contai ner in which they were shipped. (3) as tft-lcd panels are packed in a vacuum with pe bag in nitrogen gas environment , customer should keep them as the way which were shi pped to ensure 3 months warranty for storage. if customer open package in order to do inspection or any purpose , the warranty for storage should be shortened less t han 1 month. 7-5. storage 7-6. handling precautions for tft-lcd glass be careful when tft-lcd panel is broken.(tft-lcd is made of glass) www.datasheet.co.kr datasheet pdf - http://www..net/
