3. Operating Conditions
Item Conditions Temperature Range LCD Module Operating Temperature Range LCD Panel Storage Temperature Range LCD Module w/Backlight LCD Panel Surface Temperature Surface Temperature Surface Temperature -30*85C Note3-3 -40*85C -40*85C w/Backlight Ambient Temperature (Panel Surface) -30*75C *i-30*85C*j Note3-1,3-2 Remark
Note2-1: Operating temperature range defines the operation only and the contrast, response time and other display optical characteristics are set at Ta=+25C. Note2-2: Panel surface temperature indicates the temperature of the backlight panel surface on the five points from the four corners and the center. Also note that the panel temperature of backlight side is 10C (reference value) higher than the other side. Note2-3: Backlight is not activated.

Black sports : Any pixel that is below 50% of maximum luminance when white signal(V sig=0V) is inputted. Luminance irregularities and discoloration spots. Same as stain with more area. Same as stain but in linear shape. Same as stain, but in arc, spirals, or moire shape. Others that are formed from concentration of irregular patterns.

(B) Spot Defect Inspection Standards and Criteria. White spots inspection criteria Include below with the 8.2.1.conditions for common inspection Luminance : 200*250 [lx] Distance : 45*50 [cm] (Perpendicular from panel surface) Time : 5 [S] (After ND filter has been placed) Surface Brightness : 300320*@ [cd/m 2] Standard
Type Level 1 White Spots Level 1-2 White Spots Level 1-3 White Spots Black spots Total Acceptabl e No. O R T U V Criteria Visible through 0.3%ND filter Visible through 1.0%ND filter, and not visible through 0.3%ND filter Visible through 2.5%ND filter, and not visible through 1.0%ND filter Any visible black spots on Vsig=1V(All white cluster) Total white and black spots in level 1-3
Any spots that are not visible through 2.5% ND filters and not within level 1-3 is disregarded. ** Density: Only up to 2(white or black) are allowed for diameter withinO 10mm. If it is continuos, then continuos spot is applied. Continuos spot : Any spot that continues for more then 3 pixels is not acceptable. For 2 continuos white spots, treat as one spot for the table above. For 2 continuos black spots, treat as two spots for the table above. For 2 continuos white and black spot, treat as one each. White & black spot: If the pixel holds both white and black spot (level 1-3), treat as white spot for the table above. Foreign Substance(within Cell): Foreign substance shall not be more then 3-pixel size. If the size of substance is 2 to 3-pixel, then count as 2 in acceptable value. If the size of substance is 1 to 2-pixel, then count as 2 in acceptable value. If the size of substance is smaller then 1 pixel, then disregard.

12. Precautions Relating Product Handling
The Following precautions will guide you in handling our product correctly. 1) Liquid crystal display devices 1. The liquid crystal display device panel used in the liquid crystal display module is made of plate glass. Avoid any strong mechanical shock. Should the glass break handle it with care. 2. The polarizer adhering to the surface of the LCD is made of a soft material. Guard against scratching it. 2) Care of the liquid crystal display module against static electricity discharge. 1. When working with the module, be sure to ground your body and any electrical equipment you may be using. We strongly recommend the use of anti static mats ( made of rubber ), to protect work tables against the hazards of electrical shock. 2. Avoid the use of work clothing made of synthetic fibers. We recommend cotton clothing or other conductivity-treated fibers. 3. Slowly and carefully remove the protective film from the LCD module, since this operation can generate static electricity. 3) When the LCD module alone must be stored for long periods of time: 1. Protect the modules from high temperature and humidity. 2. Keep the modules out of direct sunlight or direct exposure to ultraviolet rays. 3. Protect the modules from excessive external forces. 4) Use the module with a power supply that is equipped with an overcurrent protector circuit,since the module is not provided with this protective feature. 5) Do not ingest the LCD fluid itself should it leak out of a damaged LCD module. Should hands or clothing come in contact with LCD fluid, wash immediately with soap. 6) Conductivity is not guaranteed for models that use metal holders where solder connections between the metal holder and the PCB are not used. Please contact us to discuss appropriate ways to assure conductivity. 7) For models which use CFL: 1. High voltage of 1000V or greater is applied to the CFL cable connector area. Care should be taken not to touch connection areas to avoid burns. 2. Protect CFL cables from rubbing against the unit and thus causing the wire jacket to become worn. 3. The use of CFLs for extended periods of time at low temperatures will significantly shorten their service life. 8) For models which use touch panels: 1. Do not stack up modules since they can be damaged by components on neighboring modules. 2. Do not place heavy objects on top of the product. This could cause glass breakage. 9) For models which use COG,TAB,or COF: 1. The mechanical strength of the product is low since the IC chip faces out unprotected from the rear. Be sure to protect the rear of the IC chip from external forces. 2. Given the fact that the rear of the IC chip is left exposed, in order to protect the unit from electrical damage, avoid installation configurations in which the rear of the IC chip runs the risk of making any electrical contact.

10) Models which use flexible cable, heat seal, or TAB: 1. In order to maintain reliability, do not touch or hold by the connector area. 2. Avoid any bending, pulling, or other excessive force, which can result in broken connections. 11) In case of buffer material such as cushion / gasket is assembled into LCD module, it may have an adverse effect on connecting parts ( LCD panel-TCP / HEAT SEAL / FPC / etc., PCB-TCP / HEAT SEAL / FPC etc., TCP-HEAT SEAL, TCP-FPC, HEAT SEAL-FPC, etc.,) depending on its materials. Please check and evaluate these materials carefully before use. 12) In case of acrylic plate is attached to front side of LCD panel, cloudiness ( very small cracks ) can occur on acrylic plate, being influenced by some components generated from polarizer film.. Please check and evaluate those acrylic materials carefully before use.
