7Electro-Optical Characteristics
*Note 1: Definition of contrast ratio
Contrast Ratio (CR) is defined mathematically by the following formula.
CONTRAST RATIO = Luminance measured when LCD on the "White" State
Luminance measured when LCD on the "Black" State
*Note 2: Definition of surface luminance
Surface luminance is the LCD luminance from the surface with all pixels displaying white.
Lv = Average Surface Luminance with all white pixels (P1,P2,P3 …Pn)
*Note 3: Definition of luminance uniformity
The luminance uniformity in surface luminance (Yu) is determined by measuring luminance at each test position 1 through n,
and then dividing the maximum luminance of n point’s luminance by minimum luminance of n points luminance.
Yu = Minimum Surface Luminance with all white pixels (P1,P2,P3 …Pn
Maximum Surface Luminance with all white pixels (P1,P2,P3 …Pn)
*Note 4: Definition of Response time
The response time is defined as the LCD optical switching time interval between “White” state and “Black” state. Rise time
(TON) is the time between photo detector output intensity changed from 90% to 10%. And fall time (TOFF) is the time
between photo detector output intensity changed from 10% to 90%.
*Note 5: Definition of color chromaticity (CIE1931)
CIE (x, y) chromaticity, the x, y value is determined by screen active area center position P5.
*Note 6: Definition of Viewing angle.
Viewing angle is the angle at which the contrast ratio is greater than 10. The angles are determined for the horizontal or x
axis and the vertical or y axis with respect to the z axis which is normal to the LCD surface.
For Viewing angle and response time testing, the testing data is based on Autronic-Melchers’s ConoScope or DMS series
Instruments or compatible. For contrast ratio, Surface Luminance, Luminance uniformity and CIE, the testing data is based on
TOPCON’s BM-7 or BM-5 photo detector or compatible.
*Note 7:For TFT module, Gray scale reverse occurs in the direction of panel viewing angle.

Sampling plan according to GB/T2828.1-2003/ISO 2859-1: 1999 and ANSI/ASQC Z1.4-1993, normal level 2 and
based on:
Major defect: AQL 0.65
Minor defect: AQL 1.5
12.3 Inspection condition
Viewing distance for cosmetic inspection is about 30±5cm with bare eyes, and under a 600~1000lux
environment for visual inspection and 0~200lux for function test. All directions for inspecting the sample
should be within 45°against perpendicular line. (Normal temperature 1828C and normal humidity
6015RH).
During testing, the LCD is driven using the voltage level (Within 0.5V of the typical value at 25C.) that
provides the most optical contrast

Zone A: character/Digit area
Zone B: viewing area except Zone A (Zone A + Zone B=minimum Viewing area)
Zone C: Outside viewing area (invisible area after assembly in customer’s product)
*Note: As a general rule, visual defects in Zone C are permissible, if it does not affect display quality and assembly of
customer’s product.

13 Handling Precautions
13.1 Mounting method
Do not make extra holes in the display or modify its shape. When mounting the display, ensure that the display
does not flex, bend or twist. Extreme care should be used when handling the LCD modules.
13.2 LCD Handling and Cleaning Precaution
To clean the display surface, it is recommended to wipe lightly using a soft cloth with either Isopropyl alcohol or
Ethyl alcohol.
Do not wipe the display surface with dry or hard materials as it may damage the polarizer surface.
Do not use Water or Aromatics to clean the display.
Do not wipe ITO pad area with dry or hard materials that will damage the ITO patterns
Do not use Soldering flux, Chlorine(Cl), and Sulfur(S) on the pad or prevent it from being contaminated.
If the display is sent without applying a silicon coat on the pad, the ITO patterns could be damaged due to
corrosion as time goes on.
If ITO corrosion occurs due to customer miss-handling, or if the customer applies materials such as Chlorine (CI),
Sulfur (S) to the display, the responsibility is placed the customer.
13.3 Static Charge Precaution
The LCD module uses CMOS LSI drivers, so we recommend that you:
Connect any unused input terminal to VDD or VSS
Do not input any signals before power is turned on
Ground your body, work/assembly areas, and assembly equipment to protect against static electricity.
13.4 Packing
The module employs 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
13.5 Precautions during Operation
It is an indispensable condition to drive the LCD module within the specified voltage limits. Applying
voltage higher than the limit will reduce the life span of the LCD.
Using direct drive current should be avoided, as it will induce an electrochemical reaction causing
undesirable deterioration.
The LCD’s response time will be delayed when operating at a temperature lower than the suggested
operating range. When operating at a temperature higher than the suggested range, the LCD will be
noticeably darker. The display will return to normal when it is brought back to the specified operation
temperature.
If the display area is pushed hard during operation, some font may be abnormally drawn but the LCD will
return to normal after it is reset.
Slight dew depositing on terminals can cause an electro-chemical reaction, damaging traces and resulting
in an open circuit.
Usage under the maximum operating temperature, 50%Rh or less is required

MOP-TFT320240-35A-BLM-CTB 16
13.6 Storage Recommendations
When storing the LCD for a prolonged period of time, the following recommendations will help prevent damage or
deterioration
Store the display in an ambient temperature range between 10°C to 30°C, and in a relative humidity of
45% to 75%.
Do not leave the display exposed to sunlight or fluorescent light.
Place the display in a polyethylene bag with the opening sealed.
Ensure that nothing is making contact with the polarizer surface.
It is recommended to store them in the same packaging that was provided upon purchase
13.7 Safety Precautions
