Note (2) If the PWM control duty ratio is less than 10%, it is difficult to control the brightness linearity

Note (3) If PWM control frequency is applied in the range less than 1KHz, the “waterfall” phenomenon on

the screen may be found. To avoid the issue, it’s a suggestion that PWM control frequency should

follow the criterion as below.

acoustic noise test. The test condition refers to ISO-7779 and is shown as the following figure.

8. PRECAUTIONS

8.1 HANDLING PRECAUTIONS

(1) The module should be assembled into the system firmly by using every mounting hole. Be careful

not to twist or bend the module.

(2) While assembling or installing modules, it can only be in the clean area. The dust and oil may cause

electrical short or damage the polarizer.

(3) Use fingerstalls or soft gloves in order to keep display clean during the incoming inspection and

assembly process.

(4) Do not press or scratch the surface harder than a HB pencil lead on the panel because the polarizer

is very soft and easily scratched.

(5) If the surface of the polarizer is dirty, please clean it by some absorbent cotton or soft cloth. Do not

www.panelook.com

PRODUCT SPECIFICATION

use Ketone type materials (ex. Acetone), Ethyl alcohol, Toluene, Ethyl acid or Methyl chloride. It

might permanently damage the polarizer due to chemical reaction.

(6) Wipe off water droplets or oil immediately. Staining and discoloration may occur if they left on panel

for a long time.

(7) If the liquid crystal material leaks from the panel, it should be kept away from the eyes or mouth. In

case of contacting with hands, legs or clothes, it must be washed away thoroughly with soap.

(8) Protect the module from static electricity, it may cause damage to the C-MOS Gate Array IC.

(9) Do not disassemble the module.

(10) Do not pull or fold the LED wire.

(11) Pins of I/F connector should not be touched directly with bare hands.

8.2 STORAGE PRECAUTIONS

(1) High temperature or humidity may reduce the performance of module. Please store LCD module

within the specified storage conditions.

(2) It is dangerous that moisture come into or contacted the LCD module, because the moisture may

damage LCD module when it is operating.

(3) It may reduce the display quality if the ambient temperature is lower than 10 ºC. For example, the

response time will become slowly, and the starting voltage of LED will be higher than the room

temperature.

8.3 OPERATION PRECAUTIONS

(1) Do not pull the I/F connector in or out while the module is operating.

(2) Always follow the correct power on/off sequence when LCD module is connecting and operating.

This can prevent the CMOS LSI chips from damage during latch-up.

(3) The startup voltage of Backlight is approximately 1000 Volts. It may cause electrical shock while

assembling with converter. Do not disassemble the module or insert anything into the Backlight unit.

Appendix. LCD MODULE INSPECTION SPECIFICATION

A. Description

These inspection standards shall be applied to LCD Module supplied by CHI MEI Optoelectronics

Corporation.

B. The environmental condition of inspection

The environmental condition and visual inspection shall be conducted as below.

(1) Ambient temperature : 15~25℃

(2) Humidity: 25~75 %RH

(3) External appearance inspection shall be conducted by using a single 20W fluorescent lamp or equivalent

illumination.

(4) Panel visual inspection on the operation condition for cosmetic shall be conducted at the distance 30cm

between the LCD module and eyes of inspector.

(5) Using method for ND Filter

When using ND Filter for judging Mura, placing ND Filter near Mura defect and get close to the

surface of LCD Panel (its distance shall be 1~2cm between the surface of Panel and ND Filter).

Don’t touch the surface of polarizer to avoid scratching polarizer, and then move to the defect

position to judge mura by view angel 90 degree (The viewing angle shall be 90 degree to the right top

of Mura defect with panel)

C. Classification of defects

Defects are classified two types, major defect and minor defect according to the defect. And, the definition of

defects is classified as below.

(1) Major defect

Any defect may result in functional failure, or reduce the usability of product for its purpose. For example,

electrical failure, deformation and etc..

(2) Minor defect

A defect that is not to reduce the usability of product for its intended purpose and un-uniformity, dot defect and

etc..

The criteria on major and/or minor judgement will be according with the classification of defects.

D. Inspection Criteria

(1) Definition of dot defect
