Note 1: Definition of optical measurement system Temperature = 25 (±3 ); LED back-light: ON, Environment brightness < 150 lx Note 2: Contrast ratio is defined as follow: Contrast Ratio = Surface Surface Luminance Luminance with with all white all black pixels pixels Note 3: Response time is defined as follow: Response time is the time required for the display to transition from black to white (Rise Time, Tr) and from white to black(decay Time, Tf) Page 16 of 20
Note 4: Viewing angle range is defined as follow: Viewing angle is measured at the center point of the LCD Note 5: Color chromaticity is defined as follow: (CIE1931) Color coordinates measured at center point of LCD area of RGB triangle S 100% area of NTSC triangle Note 6: Luminance is defined as follow: Luminance is defined as the brightness of all pixels White at the center of display area on optimum contrast Page 17 of 20
Note 7: Reflectance measurement system is defined as follow: Note 8: Luminance Uniformity is defined as follow: Active area is divided into 9 measuring areas (Refer Fig 2) Every measuring point is placed at the center of each measuring area Uniformity (U) = Minimum Luminance( brightness ) in 9 points Maximum Luminance( brightness ) in 9 points Fig 2 Definition of uniformity Page 18 of 20

11 Precautions for Use of LCD Modules 101 Safety The liquid crystal in the LCD is poisonous Do not put it in your mouth If the liquid crystal touches your skin or clothes, wash it off immediately using soap and water 102 Handling A The LCD and touch panel is made of plate glass Do not subject the panel to mechanical shock or to excessive force on its surface B Do not handle the product by holding the flexible pattern portion in order to assure the reliability C Transparency is an important factor for the touch panel Please wear clear finger sacks, gloves and mask to protect the touch panel from finger print or stain and also hold the portion outside the view area when handling the touch panel D Provide a space so that the panel does not come into contact with other components E To protect the product from external force, put a covering lens (acrylic board or similar board) and keep an appropriate gap between them F Transparent electrodes may be disconnected if the panel is used under environmental conditions where dew condensation occurs G Property of semiconductor devices may be affected when they are exposed to light, possibly resulting in IC malfunctions H To prevent such IC malfunctions, your design and mounting layout shall be done in the way that the IC is not exposed to light in actual use 103 Static Electricity A Ground soldering iron tips, tools and testers when they are in operation B Ground your body when handling the products C Power on the LCD module before applying the voltage to the input terminals D Do not apply voltage which exceeds the absolute maximum rating E Store the products in an anti-electrostatic bag or container 104Storage A Store the products in a dark place at +25 ±10 with low humidity (40% RH to 60% RH) Don't expose to sunlight or fluorescent light B Storage in a clean environment, free from dust, active gas, and solvent 105 Cleaning A Do not wipe the touch panel with dry cloth, as it may cause scratch B Wipe off the stain on the product by using soft cloth moistened with ethanol Do not allow ethanol to get in between the upper film and the bottom glass It may cause peeling issue or defective operation Do not use any organic solvent or detergent other than ethanol 106 Cautions for installing and assembling Bezel edge must be positioned in the area between the Active area and View area The bezel may press the touch screen and cause activation if the edge touches the active area A gap of approximately 05mm is needed between the bezel and the top electrode It may cause unexpected activation if the gap is too narrow There is a tolerance of 02 to 03mm for the outside dimensions of the touch panel and tail A gap must be made to absorb the tolerance in the case and connector Page 20 of 20
