Should this range is exceeded, the operation cannot be guaranteed even if the values may be without the absolute maximum ratings. Note 3: If LED is driven by high current, high ambient temperature & humidity condition. The life time of LED will be reduced. Operating life means brightness goes down to 50% initial brightness. Typical operating life time is estimated data. www.rocktech.com.hk RK043FN02H-CT 3.3 Driving CTP Item Value Working Voltage DC 2.8-3.3V Insulation Resistance >20M Working Current 12.5mA Response Time 1MΩ) should be used. In case of malfunction defect caused by ESD damage, if it would be recovered to normal state after resetting, it would be judged as a good part. EL evaluation should be excepted from reliability test with humidity and temperature: Some defects such as black spot/blemish can happen by natural chemical reaction with humidity and fluorescence EL has. After the reliability test, the test samples should be inspected after 2 hours at least. Functional test is OK. Missing segment, shorts, unclear segment, non display, display abnormally, liquid crystal leak are not allowed. After testing, the current Idd should be within initial value ±20%. No low temperature bubbles ,end seal loose and fall, frame rainbow, ACF bubble growing are allowable in the appearance test. www.rocktech.com.hk RK043FN02H-CT 10.PRECAUTIONS FOR USING LCD MODULES Handing Precautions (1) The display panel is made of glass and polarizer. As glass is fragile, it tends to become or chipped during handling especially on the edges. Please avoid dropping or jarring. Do not subject it to a mechanical shock by dropping it or impact. (2) If the display panel is damaged and the liquid crystal substance leaks out, be sure not to get any in your mouth. If the substance contacts your skin or clothes, wash it off using soap and water. (3) Do not apply excessive force to the display surface or the adjoining areas since this may cause the color tone to vary. Do not touch the display with bare hands. This will stain the display area and degraded insulation between terminals (some cosmetics are determined to the polarizer). (4) The polarizer covering the display surface of the LCD module is soft and easily scratched. Handle this polarizer carefully. Do not touch, push or rub the exposed polarizers with anything harder than an HB pencil lead (glass, tweezers, etc.). Do not put or attach anything on the display area to avoid leaving marks on. Condensation on the surface and contact with terminals due to cold will damage, stain or dirty the polarizer. After products are tested at low temperature they must be warmed up in a container before coming is contacting with room temperature air. (5) If the display surface becomes contaminated, breathe on the surface and gently wipe it with a soft dry cloth. If it is heavily contaminated, moisten cloth with one of the following solvents - Isopropyl alcohol - Ethyl alcohol Do not scrub hard to avoid damaging the display surface. (6) Solvents other than those above-mentioned may damage the polarizer. Especially, do not use the following. - Water - Ketone - Aromatic solvents Wipe off saliva or water drops immediately, contact with water over a long period of time may cause deformation or color fading. Avoid contacting oil and fats. (7) Exercise care to minimize corrosion of the electrode. Corrosion of the electrodes is accelerated by water droplets, moisture condensation or a current flow in a highhumidity environment. (8) Install the LCD Module by using the mounting holes. When mounting the LCD module make sure it is free of twisting, warping and distortion. In particular, do not forcibly pull or bend the I/O cable or the backlight cable. (9) Do not attempt to disassemble or process the LCD module. (10) NC terminal should be open. Do not connect anything. (11) If the logic circuit power is off, do not apply the input signals. (12) Since LCM has been assembled and adjusted with a high degree of precision, avoid applying excessive shocks to the module or making any alterations or modifications to it. - Do not alter, modify or change the shape of the tab on the metal frame. - Do not make extra holes on the printed circuit board, modify its shape or change the positions of components to be attached. - Do not damage or modify the pattern writing on the printed circuit board. - Absolutely do not modify the zebra rubber strip (conductive rubber) or heat seal www.rocktech.com.hk RK043FN02H-CT connector. - Except for soldering the interface, do not make any alterations or modifications with a soldering iron. - Do not drop, bend or twist LCM. Storage Precautions When storing the LCD modules, the following precaution is necessary. (1) Store them in a sealed polyethylene bag. If properly sealed, there is no need for the dessicant. (2) Store them in a dark place. Do not expose to sunlight or fluorescent light, keep the temperature between 0°C and 35°C. (3) The polarizer surface should not come in contact with any other objects. (We advise you to store them in the container in which they were shipped). Others Liquid crystals solidify under low temperature (below the storage temperature range) leading to defective orientation or the generation of air bubbles (black or white). Air bubbles may also be generated if the module is subject to a low temperature. If the LCD modules have been operating for a long time showing the same display patterns, the display patterns may remain on the screen as ghost images and a slight contrast irregularity may also appear. A normal operating status can be regained by suspending use for some time. It should be noted that this phenomenon does not adversely affect performance reliability. To minimize the performance degradation of the LCD modules resulting from destruction caused by static electricity etc., exercise care to avoid holding the following sections when handling the modules. - Exposed area of the printed circuit board. -Terminal electrode sections. www.rocktech.com.hk
