SAFETY The toxicity of liquid crystal fluid is very low, but wash it off immediately with soap and water if fluid touches the skin or clothing. HANDLING Do not touch display area with bare hands. Do not touch exposed polarizer with hard objects. Do not expose the CMOS IC s to static electricity. Avoid exposing the module to excessive shock or pressure.

It is recommended that the product be designed so that the EL back light is not left on continuously. This will greatly extend the lifo of the back light element. 2. Usable lifetime of the back light is reached when the light output reaches 5% of the original brightness. POWER SUPPLY SEQUENCING (Graphics Modules Only) The power supply voltages should be sequenced according to the following timing diagram. This will insure that the internal electronics have time to begin operation before the negative voltage is applied. The sequence of events should be as follows: Apply V DD first. When V DD is stable at 5v, apply the input signals and then apply V L /V EE. The shut down sequence is exactly the opposite. Failure to follow this procedure may result in permanent damage to the LCD fluid or to the CMOS electronics on the module. 1 second min 1second min V DD 5v v INPUT SIGNALS to 5mS 5v v - 5mS V L /V EE v Minus v sec min sec min NOTICE: Specifications in this catalog are subject to change without notice.
