T6 0.1 -- 100 ms
T7 1000 -- -- ms
Note (1) The supply voltage of the external system for the module input should be the same as the definition
of Vcc.
Note (2) When the backlight turns on before the LCD operation of the LCD turns off, the display may
momentarily become abnormal screen.
Note (3) In case of VCC = off level, please keep the level of input signals on the low or keep a high
impedance.
Note (4) T7 should be measured after the module has been fully discharged between power off and on
period.
Min Typ. Max
Values
Units
Note (5) Interface signal shall not be kept at high impedance when the power is on.
Note (6) CMI won’t take any responsibility for the products which are damaged by the customers not
following the Power Sequence.
Note (7) There might be slight electronic noise when LCD is turned off (even backlight unit is also off). To
avoid this symptom, we suggest "Vcc falling timing" to follow "t6 spec".

PRODUCT SPECIFICATION
Note (2) Definition of Contrast Ratio (CR):
The contrast ratio can be calculated by the following expression.
Contrast Ratio (CR) = L255 / L0
L255: Luminance of gray level 255
L 0: Luminance of gray level 0
CR = CR (5)
CR (X) is corresponding to the Contrast Ratio of the point X at Figure in Note (6).

Note (4) Definition of Luminance of White (LC):
PRODUCT SPECIFICATION
Measure the luminance of gray level 255 at center point
LC = L (5)
L (x) is corresponding to the luminance of the point X at Figure in Note (6).
Note (5) Measurement Setup:
The LCD module should be stabilized at given temperature for 40 minutes to avoid abrupt
temperature change during measuring. In order to stabilize the luminance, the measurement should
be executed after lighting Backlight for 40 minutes in a windless room.
Note (6) Definition of White Variation (δW):
Measure the luminance of gray level 255 at 9 points
δW = ( Minimum [L (1) ~ L (9)] / Maximum [L (1) ~ L (9)] ) *100%

7.3 Definition of Test Points
Measure the minimum force of test points at 128th Gray pattern. The test points at back
side of module area is showing as below (except PCBA).
Version 2.0 7 March 2013 23 / 33
The copyright belongs to InnoLux. Any unauthorized use is prohibited.
(1) Do not apply rough force such as bending or twisting to the module during assembly.
(2) To assemble or install module into user’s system can be only in clean working areas. The dust and oil
may cause electrical short or worsen the polarizer.
(3) It’s not permitted to have pressure or impulse on the module because the LCD panel and Backlight will
be damaged.
CANO
(4) Always follow the correct power sequence when LCD module is connecting and operating. This can
prevent damage to the CMOS LSI chips during latch-up.
(5) Do not pull the I/F connector in or out while the module is operating.
(6) Do not disassemble the module.
(7) Use a soft dry cloth without chemicals for cleaning, because the surface of polarizer is very soft and
easily scratched.
(8) It is dangerous that moisture come into or contacted the LCD module, because moisture may damage
LCD module when it is operating.
(9) High temperature or humidity may reduce the performance of module. Please store LCD module within
the specified storage conditions.
(10)When ambient temperature is lower than 10ºC may reduce the display quality. For example, the
response time will become slowly.
10.2 STORAGE PRECAUTIONS
(1) Do not leave the module in high temperature, and high humidity for a long time. It is highly recommended
to store the module with temperature from 0℃ to 35℃ and relative humidity of less than 70%
(2) Do not store the TFT – LCD module in direct sunlight
(3) The module should be stored in dark place. It is prohibited to apply sunlight or fluorescent light in storing
10.3 OPERATION PRECAUTIONS
(1) The LCD product should be operated under normal condition.
Normal condition is defined as below :
Temperature : 20±15℃

PRODUCT SPECIFICATION
(2) If the product will be used in extreme conditions such as high temperature,high humidity,high
altitude ,display pattern or operation time etc…It is strongly recommended to contact CMI for application
engineering advice . Otherwise , Its reliability and function may not be guaranteed.
10.4 SAFETY PRECAUTIONS
(1) If the liquid crystal material leaks from the panel, it should be kept away from the eyes or mouth. In case
of contact with hands, skin or clothes, it has to be washed away thoroughly with soap.
(2) After the module’s end of life, it is not harmful in case of normal operation and storage.
10.5 SAFETY STANDARDS
The LCD module should be certified with safety regulations as follows:
(1) UL60950-1 or updated standard.
(2) IEC60950-1 or updated standard.
10.6 OTHER
When fixed patterns are displayed for a long time, remnant image is likely to occur.
Appendix 1. SYSTEM COVER DESIGN NOTICE
1. Set Chassis and MNT Module touching Mode
a) To prevent from abnormal display & white spot after Mechanical test, it is not recommended to
used spring type chassis.
Definition
b) We suggest the contact mode between Chassis and Module rear cover is Tape/Sponge,
sencond is Flat sheetmetal type chassis (Don’t interference from flat sheetmeter of chassis to
rear cover of Module ).

2 Tape/sponge design on system inner surface
Definition
a) To prevent from abnormal display & white spot after Mechanical test, We suggest using
Tape/Sponge as medium between chassis and Module rear cover could reduce the
occurrence of white spot.
b) When using the Tape/Sponge, suggest it be lay over between set chassis and module rear
cover. it is not recommended to add tape/sponge in separate location. Since each
tape/sponge may act as pressure concentration location.

3 System inner surface examination
Definition
a). Burr at logo edge, step, protrusion or PCB board will easily cause white spot.
b). Keeping flat surface underneath module is recommended.
c). The area ( ) on Module PCBA and Light bar connector should keep at least 1mm gap to
any structure with System cover inner surface.

5 System cover’s ventilation outlet structure
The overlapping part on System’s Chassis and electric wire (FPCFFC and wire) needs gap
structure to avoid display of white spot by pressing overlapping part cause interference.
Definition
To prevent from abnormal display of light leakage, We suggest to set ventilation outlet
structure on side of Module Light bar in system cover inner surface.
