9. Appearance Standards
9.1 Inspection Conditions
The LCD shall be inspected under 40W white fluorescent light. The distance between the eyes and the sample shall be more than 30cm. All directions for inspecting the sample should be within 45 ?against perpendicular line.
9.2 Definition of Applicable Zones
A Zone : Active display area B Zone : Area from outside of "A Zone" to validity viewing area C Zone : Rest parts A Zone + B Zone = Validity viewing area

Polarizer Scratches Polarizer Dirts Complex Foreign Substance Defects Distance between different Foreign Substance defects
Not to be conspicuous defects. I f the stains are removed easily from LCDP surface, the module is not defective. Black spots, line shaped foreign substance or air bubbles between glass & polarizer should be 5pcs maximum in total. D ≤?0.2 : 20mm or more 0.2 ?D : 40mm or more
10.1 Operation 10.2 Safety
Burn-in sometimes happens when the same character was displayed at along time. Therefore, to prevent Burn-in, it is recommended to set up a Screen-saver function. 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.
a. The LCD module shall be installed flat , without twisting or bending. b. COF or FPC has narrow pattern width, so easily become open circuit by external force. DO NOT apply pressure to COF or FPC especially in bending area. c. To avoid damage in appearance or malfunction, DO NOT subject the module to mechanical shock or to excessive force on its surface.
d. The polarizer attached to the display is very easy to damage, handle it with care to avoid scratching
e. To avoid contamination on the display surface, DO NOT touch the display surface with bare hands. f. Provide a space so that the LCD module does not come into contact with other components components.
g. To protect the LCD panel from external pressure, put covering glass (acrylic board or similar board) to keep appropriate space between them.
h. Be careful for condensation at sudden temperature change. Condensation makes damage to polarizer or electrical contacted parts. And after fading condensation, smear or spot will occur.
i. Property of semiconductor devices may be affected when they are exposed to light possibly resulting in malfunctioning of the ICs. To prevent such malfunctioning of the ICs, your design and mounting layout done are so that the IC is not exposed to light in actual use.
j. Strong light exposure causes degradation of color filter. It may not recover
k. DO NOT contact with water to avoid Metal corrosion. l . When it is not in use, the screen must be turned off or the pattern must be frequently changed by a screen saver. If it displays the same pattern for a long period of time, brightness down/image sticking may develop due to the LCD structure. m. Never disassemble LCD product under any circumstances. If unqualified operators or users assemble the product after disassembling it, it may not function or its operation may be seriously affected.
10.4 Static electricity
Since a module is composed of electronic circuits, it is not strong to electrostatic discharge. a. The LCD module shall be installed flat, without wisting or bending. Ground they operate.soldering iron tips, tools and testers when they operat. b. Ground your body when handling the products. c. DO NOT apply voltage to the input terminal without applying power supply. d. DO NOT apply voltage that exceeds the absolute maximum rating. e. Peel off protect tape, attached to polarizer, slowly to minimize ESD damage f. Store the products in an anti-electrostatic container.
Store the products in a dark place at +5 ~+25℃, low humidity (50%RH or less). DO NOT store the products in an atmosphere containing organic solvents or corrosive gases.
DO NOT wipe the polarizer with dry cloth, as it might cause scratch. Wipe the polarizer with a soft cloth soaked with petroleum IPA, other chemica might damage.
When dispose of LCD module, manage it at the production waste according to the relevant laws and regulations.
