kaohsiung hitachi electronics co. , ltd. sheet no. page 12. precautions 12.1 precautions of esd 1) before handling the display, please ensure your body has been connected to ground to avoid any damages by esd. also, do not touch display?s interface directly when assembling. 2) please remove the protection film very slowly before turning on the display to avoid generating esd. 12.2 precautions of handling 1) in order to keep the appearance of display in good condition, please do not rub any surfaces of the displays by sharp tools harder than 3h, especially touch panel, metal frame and polarizer. 2) please do not stack the displays as this may damage the surface. in order to avoid any injuries, please avoid touching the edge of the glass or metal frame and wore gloves during handling. 3) touching the polarizer or terminal pins with bare hand should be avoided to prevent staining and poor electrical contact. 4) do not use any harmful chemicals such as ac etone, toluene, and isopropyl alcohol to clean display?s surfaces. 5) please use soft cloth or absorbent cotton with ethanol to clean the display by gently wiping. moreover, when wiping the display, please wipe it by horizontal or vertical direction instead of circling to prevent leaving scars on the display?s surface, especially polarizer. 6) please wipe any unknown liquids immediately such as saliva, water or dew on the display to avoid color fading or any permanently damages. 7) maximum pressure to the surface of the display must be less than 4 10 x 1,96 pa. if the area of adding pressure is less than 1 2 cm , the maximum pressure must be less than 1.96n. 12.3 precautions of operating 1) please input signals and voltages to the displays according to the values defined in the section of electrical characteristics to obtain the best per formance. any voltages over than absolute maximum rating will cause permanent damages to this display. also, any timing of the signals out of this specification would cause unexpected performance. 2) when the display is operating at significant low temperature, the response time will be slower than it at 25 ? c . in high temperature, the color will be slightly dark and blue compared to original pattern. however, these are temperature-related phenomenon of lcd and it will not cause permanent damages to the display when used within the operating temperature. 3) the use of screen saver or sleep mode is recommended when static images are likely for long periods of time. this is to avoi d the possibility of image sticking. 4) spike noise can cause malfunction of the circuit. the recommended limitation of spike noise is no bigger than ? 100 mv. 7b64ps 2712-TX20D19VM2BAA-3 12-1/2 www.datasheet.co.kr datasheet pdf - http://www..net/
kaohsiung hitachi electronics co. , ltd. sheet no. page 12.4 precautions of storage if the displays are going to be stored for years, please be aware the following notices. 1) please store the displays in a dark room to avoid any damages from sunlight and other sources of uv light. 2) the recommended long term storage temperature is between 10 ? c ~35 ? c and 55%~75% humidity to avoid causing bubbles between polarizer and lcd glasses, and polarizer peeling from lcd glasses. 3) it would be better to keep the displays in the container, which is shipped from hitachi, and do not unpack it. 4) please do not stick any labels on the display surface for a long time, especially on the polarizer. 12.5 mounting precaution 1) when assembling the lcm module, please refer to the below. 2) the use of cushion is recommended in order to protect the module from shock. 7b64ps 2712-TX20D19VM2BAA-3 12-2/2 www.datasheet.co.kr datasheet pdf - http://www..net/
