IS01BFRGB Version (1) DISTINCTIVE CHARACTERISTICS Enhanced LED Illumination with: • Broad and even light distribution • Consistent bright backlighting • Lower energy consumption Programmable to display graphics, alphanumeric characters and animated sequences. SMARTDISPLAY can be used alone or in conjunction with electromechanical switches. Integrated liquid crystal display provides wide viewing angle with high contrast and clarity. Viewing area 13.9mm x 10.6mm (horizontal x vertical) at 36 x 24 pixels. Epoxy sealed terminals prevent entry of solder flux and other contaminants. Optional accessories available to enhance panel design and simplify production process. Built-in RGB LED backlighting enhances display and provides numerous color variations. PRECAUTIONS FOR HANDLING & STORAGE Handling 1. 2. 3. 4. 5. 6. 7. The VLC voltage should not be applied before logic voltage. If VLC voltage is present before logic voltage, it may cause the driver logic to freeze and damage the LCD, and the driver logic itself may become damaged. The IS Series devices are electrostatic sensitive. ATTENTION ELECTROSTATIC Recommended soldering time and temperature limits are 5 seconds maximum @ 270°C maximum. SENSITIVE DEVICES Do not exceed 60°C at the LCD level. The IS series devices are not process sealed. If the LCD is accidentally broken, avoid contact with the liquid and wash off any liquid spills to the skin or clothing. Clean cap surface with dry cloth. If further cleaning is needed, wipe with dampened cloth using neutral cleanser and dry with clean cloth. Do not use organic solvent. Storage 1. Store away from direct sunlight. 2. Keep away from static electricity. 3. Avoid extreme temperatures, high humidity, gaseous substances, and all forms of chemical contamination.
