9. Reliability Test Conditions And Methods



10.Inspection Standard

This standard apply to C-STN/TFT module

1. Spot check plan：

According to spot check level Ⅱ,MIL-STD-105D Level Ⅱ,the rank of accept or reject

is below:

3A level、2A level：major non-conformance：AQL 0.25 minor non-conformance：AQL 0.4

A level：major non-conformance： AQL 0.65 minor non-conformance： AQL 1.

2. Inspection condition：

Under daylight lamp 20～40W，product distance inspector’eye 30cm,incline degree30°。

3. LCD area define：

Area A：display area

Area B：VA area

Area C：out of VA area,not in sight after assemby

Remark：non-conformance at area C,but is OK that isn’t influence raliability of product &assembly by customer.

11. Handling Precautions

11.1 Mounting method

easily be damaged. And since the module in so constructed as to be fixed by utilizing fitting holes in theprinted circuit board.

Extreme care should be needed when handling the LCD modules.

11.2 Caution of LCD handling and cleaning

When cleaning the display surface, Use soft cloth with solvent[recommended below] and wipe lightly

Isopropyl alcohol Ethyl alcohol

Do not wipe the display surface with dry or hard materials that will damage the polarizer surface.Do not use the following solvent: Water Aromatics

Do not wipe ITO pad area with the dry or hard materials that will damage the ITO patternsDo not use the following solvent on the pad or prevent it from being contaminated: Soldering flux Chlorine (Cl) , Salfur (S)

If goods were sent without being sili8con coated on the pad, ITO patterns could be damaged dueto the corrosion as time goes on.

If ITO corrosion happen by miss-handling or using some materials such as Chlorine (CI), Salfur (S)from customer, Responsibility is on customer.

11.3 Caution against static charge

The LCD module use C-MOS LSI drivers, so we recommended that you:Connect any unused input terminal to Vdd or Vss, do not input any signals before power is turned

on, and ground your body, work/assembly areas, assembly equipment to protect against staticelectricity.

11.4 packing

Module employ LCD elements and must be treated as such. Avoid intense shock and falls from a height. To prevent modules from degradation, do not operate or store them exposed direct to sunshine or

high temperature/humidity

11.5 Caution for operation

It is an indispensable condition to drive LCD’s within the specified voltage limit since the highervoltage then the limit cause the shorter LCD life.

An electrochemical reaction due to direct current causes LCD’s undesirable deterioration, so thatthe use of direct current drive should be avoided.

Response time will be extremely delayed at lower temperature then the operating temperaturerange and on the other hand at higher temperature LCD’s how dark color in them. Howeverthose phenomena do not mean malfunction or out of order with LCD’s, which will come back inthe specified operation temperature.

If the display area is pushed hard during operation, some font will be abnormally displayed but itresumes normal condition after turning off once.

A slight dew depositing on terminals is a cause for electro-chemical reaction resulting in terminalopen circuit.

Usage under the maximum operating temperature, 50%Rh or less is required.

The LCD panel of Co.,ltd module consists of two thin glass plates with polarizes which

11.6 storage

In the case of storing for a long period of time for instance, for years for the purpose or replacementuse, the following ways are recommended. Storage in a polyethylene bag with the opening sealed so as not to enter fresh air outside in it .

And with no desiccant. Placing in a dark place where neither exposure to direct sunlight nor light’s keeping the storage

temperature range. Storing with no touch on polarizer surface by the anything else.

[It is recommended to store them as they have been contained in the inner container at the timeof delivery from us

11.7 Safety It is recommendable to crash damaged or unnecessary LCD’s into pieces and wash off liquid

crystal by either of solvents such as acetone and ethanol, which should be burned up later.When any liquid leaked out of a damaged glass cell comes in contact with your hands, please

wash it off well with soap and water

12. Precaution For Fse12.1

A limit sample should be provided by the both parties on an occasion when the both parties agreedits necessity. Judgment by a limit sample shall take effect after the limit sample has been establishedand confirmed by the both parties.

12.2On the following occasions, the handing of problem should be decided through discussion and

agreement between responsible of the both parties. When a question is arisen in this specification When a new problem is arisen which is not specified in this specifications When an inspection specifications change or operating condition change in customer is reported

sen in this specification due to the changeWhen a new problem is arisen at the customer’s operating set for sample evaluation in the

customer site.
