The LED lifetime could be decreased if operating IL is larger than40mA. Note 2: Backlight should be driven in constant current mode. Use a supply voltage of 17 Volts or higher with a series resistor to limit the current to 40 mA (e.g. (17V - (5 x 3.2V) )/0.040 = 25 ohms). Alternatively, the backlight can be driven from lower voltages with a boost LED driver such as the ON Semiconductor CAT4139. 6 DT043BTFT-PTS1 Displaytech Ltd. Rev 0.0 8.

Precautions for Use of LCD Modules 10.1 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. 10.2 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. 10 Displaytech Ltd. DT043BTFT-PTS1 Rev 0.0 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. 10.3 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. 10.4 Storage a. Store the products in a dark place at +25C±10C 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. 10.5 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. 10.6 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 0.5mm 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 0.2 to 0.3mm for the outside dimensions of the touch panel and tail. A gap must be made to absorb the tolerance in the case and connector. 11
