MG 780F-LR 5.0 Inspection Specifications 5.1 Inspection Level This section specifies failure criteria and failure rate for the LCD Assembly. All series production LCD assembly shall be tested 100% prior to shipment for further processing. The LCD assembly shall be considered a failing unit when it no longer meets any of the requirements stated in this specification. The display assembly shall be considered a failing unit when any one of the following occur : * The back light output drops down to 40% luminance (FOS) of the initial value. * Any screen defects which belong to the failure of the LCD electrical circuitry. * Any lead or wire breaking caused by corrosion and of mechanical/thermal shock. * Wire / cables / connectors / glass plates failure in any manner affecting form, fit function or reliability. * Bad viewing angle in wrong position. * Segment shorts (automatic test). * Unreliable contacts (flickering of entire display or of individual segments). Class Critical Defects Contents No display turn on, inappropriate SEG turn on, AQL (%) 0.25 functional defect Major Defects Electrical, optical, mechanical parameters out of spec. 1.00 without affecting functions. Minor Defects Black spots, foreign substances, pin hole segment, deformation, scratches (polarizer), air bubbles between glass & polarizer, color variations, polarizer dirt, other visual defects. 8 2.50 Optrex America, Inc.

MG 780F-LR 6.0 Precautions For Use Of LCD Module 6.1 Handling Precautions The display panel is made of glass. Do not subject it to a mechanical shock by dropping it from a high place. If the display panel is damaged and the liquid crystal substance inside it leaks out, be sure not to get any in your mouth. If the substance comes into contact with your skin or clothes, please immediately wash it off using soap and water. Do not apply excessive force on the surface of display or the adjoining areas of LCD module since this may cause the color tone or vary. To prevent destruction of the elements by static electricity, be careful to maintain an optimum work environment. * Please be sure to ground human body and electric appliances during work. * It is preferable to use conductive mat on table and wear cotton clothes or conduction processed fiber. * Slowly peel off protective film since static electricity may be generated. 6.2 Storage Precautions When storing the LCD module, avoid exposure to direct sunlight or to the light of fluorescent lamps. Keep the LCD module in bags provided to prevent static electricity charging under low temperature (0C to 25C) / normal humidity conditions (avoid high temperature / high humidity and low temperature below 0 C). If storage condition is not satisfactory, display (especially polarizer) may be deteriorated or soldering I/O terminals may become difficult (some oxide is generated at I/O terminals plating). 6.3 Design Precautions The absolute maximum ratings represent the rated value beyond which LCD module cannot exceed. When LCD module is used in excess conditions, their operating characteristics may be adversely affected. The liquid crystal display exhibits temperature dependency characteristics, be sure to use the LCD module within the specified range. To prevent the occurrence of erroneous operation caused by noise, attention must be paid to satisfy the VIL, VIH specification values. 11 Optrex America, Inc.
