All input terminals LCD panel must be ground while measuring the center area of the panel. 2. Contrast measurements shall be made at viewing angle of Θ= 0 and at the center of the LCD surface. Luminance shall be measured with all pixels in the view field set first to white, then to the dark (black) state. (see Figure 4) Luminance Contrast Ratio (CR) is defined mathematically Note (2) Definition of Response Time (TR, TF): AZ DISPLAYS 10 ATM0700L26(AZ DISPLAYS) TFT MIDULE V1.0 Note (3) Definition of viewing Angle: Viewing angle is the angle at which the contrast ratio is greater than 10. The viewing angles are determined for the horizontal or 3, 9 o‟ clock direction and the vertical or 6, 12 o‟ clock direction with respect to the optical axis which is normal to the LCD surface. Note (4) Definition of optical measurement system. The optical characteristics should be measured in dark room. The optical properties are measured at the center point of the LCD screen,(Response time is measured by Photo detector TOPCON BM-7, other items are measured by BM-5A/Field of view :1 ° /Height 500mm.) AZ DISPLAYS 11 ATM0700L26(AZ DISPLAYS) TFT MIDULE V1.0 Note (5) Definition of Transmittance Where LMOD defined as measured luminance at center point of MOD with ” White” state LBL defined as measured luminance at center point of Backlight Unit with same MOD. The Backlight Unit has composite optical films, except “gain” characteristic optical films. Tr% = (LMOD / LBL )*100% 6 Reliability Test Items NO.

If the liquid crystal contacts with your skin, mouse or clothes, use soap to wash it off immediately. 7.2 Handling i. The LCD panel is made by thin glass. Prevent the panel from mechanical shock or putting excessive force on its surface. ii. The polarizer attached on the display is very easy to be damaged, handle it with special attention. iii. To avoid contamination on the display surface, do not touch the display surface with bare hands. iv. The transparent electrodes may be disconnected if you use the LCD panel under dew-condensing environment. v. The characteristics of the semiconductor devices may be affected when they are exposed to light, possibly resulting in malfunctioning of the ICs. To prevent such malfunctioning of the ICs, make sure the application and the mounting of the panel are designed so that the IC is not exposed to light. 7.3 Static Electricity Ground soldering iron tips, tools and testers when you operate. Also ground your body when handling the products and store the products in an anti-electrostatic container. 7.4 Storage Store the products in a dark place where the temperature is within the range of 25±10 and with low humidity (65%RH or less). Do not store the LCD product in an atmosphere containing organic solvents or corrosive gases. 7.5 Cleaning Do not wipe the polarizer with dry cloth, as it might cause scratching. Wipe the polarizer with a soft cloth soaked with petroleum IPA. Other chemical might damage the panel.
