NOTES:

Backlight drive conditions: constant current driving method.








The LED driving condition is defined for the module (6 dual core LED Serial x 6 Parallel).
The LED driving condition is defined for total backlight consumption and the driver circuit.
Forward Voltage adjustment depends on the Forward Current setting.
One LED : max IF = 50mA, VF = 3.5V
The LED lifetime is typically 20,000 hours at 25degC.

IF =240mA is defined for all channels LEDs.
If the LEDs are driven by high current, high ambient temperature & humidity condition the
lifetime of the LEDs will be reduced.
Operating life means brightness reduces to 50% of initial brightness and typical operating life
time is estimated data.

Test Conditions: DVDD=3.3V, IL=480mA (Backlight current), the ambient temperature is 25℃.
Optical performance should be evaluated at Ta=25℃ only.
NOTES
1. Contrast ratio (CR) is defined mathematically in Figure 2.
Contrast Ratio = Average Surface Luminance with all white pixels (P1, P2, P3, P4, P5)
Average Surface Luminance with all black pixels (P1, P2, P3, P4, P5)
Note 2. Surface luminance is the LCD surface from the surface with all pixels displaying white.
For more information see figure 2.
Lv = Average Surface Luminance with all white pixels (P1, P2, P3, P4, P5…)
Note 3. Uniformity of surface luminance,  White, is defined mathematically in figure 2.
 White = Minimum Surface Luminance with all white pixels (P1, P2, P3, P4, P5)
Maximum Surface Luminance with all white pixels (P1, P2, P3, P4, P5)
Note 4. Response time is the time required for the display to transition form white to black (rise timeTr) and from black to white (decay or fall time, Tf). The industry standard test equipment used is theAutronic-Melcher’s Conoscope.

Note 5. CIE (x,y) chromaticity. The x,y value is determined by measuring luminance at each test
position 1 through 5, then calculating the average value.
Note 6. The Viewing angle is the angle at which the contrast ratio is greater than 2. For a TFT
module, 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, being the LCD surface reference. Also see
figure 3.
Note 7. For viewing angle and response time testing, the testing data is based on Autronic-Melcher’s
BM-7A. For the contrast ratio, surface luminance, luminance uniformity and chromaticity (CIE), thetest data is based on the industry’s standard SR-3A photo detector.
Note 8. For TFT modules, grey scale reversing occurs in the direction of the panel viewing angle.

PRECAUTIONS FOR USING LCD MODULES
 HANDLING PRECAUTIONS(1) The display panel is made of glass. Do not subject it to a mechanical shock by dropping it or
impact.
(2) If the display panel is damaged and the liquid crystal substance leaks out, be sure not to get any
in your mouth. If the substance contacts your skin or clothes, wash it off using soap and water.
(3) Do not apply excessive force to the display surface or the adjoining areas since this may cause
the color tone to vary.
(4) The polarizer covering the display surface of the LCD module is soft and easily scratched.
Handle this polarizer carefully.
(5) If the display surface becomes contaminated, breathe on the surface and gently wipe it with asoft dry cloth. If it is heavily contaminated, moisten cloth with one of the following solvents:- Isopropyl alcohol- Ethyl alcohol(6) Solvents other than those above-mentioned may damage the polarizer. Especially, do not use
the following.
- Water- Ketone- Aromatic solvents(7) Exercise care to minimize corrosion of the electrode. Water droplets, moisture condensation or
current flow in a high-humidity environment, accelerate corrosion of the electrodes.
25/27

Logic Technologies

Part Number : LT170410-2WHC

Issue Date : 31.07.2019

Version : 1.1(8) Install the LCD Module by using the mounting holes. When mounting the LCD module ensure itis free of twisting, warping or distortion.
(9) Do not attempt to disassemble the LCD module.
(10) NC terminal should be open. Do not connect anything.
(11) If the logic circuit power is off, do not apply the input signals.
(12) To prevent destruction of the elements by static electricity, be careful to maintain an optimum
work environment.
- Be sure to ground the body when handling the LCD modules.
- Tools required for assembling, such as soldering irons, must be properly grounded.
- To reduce the amount of static electricity generated, do not conduct assembling and otherwork under dry conditions.
- The LCD module is coated with a film to protect the display surface. Exercise care when
peeling off this protective film since static electricity may be generated.



STORAGE PRECAUTIONSWhen storing the LCD modules, the following precaution is necessary.
(1) Store them in a sealed polyethylene bag. If properly sealed, there is no need for the dessicant.
(2) Store them in a dark place. Do not expose to sunlight or fluorescent light, keep the temperature
between 0°C and 35°C, and keep the relative humidity between 40%RH and 60%RH.
(3) The polarizer surface should not come in contact with any other objects. (We advise you tostore them in the anti-static electricity container in which they were shipped.



OTHERS

Liquid crystals solidify under low temperature (below the storage temperature range) leading
to defective orientation or the generation of air bubbles (black or white). Air bubbles may also be
generated if the module is subject to a low temperature.
If the LCD modules have been operating for a long time showing the same display patterns,
the display patterns may remain on the screen as ghost images and a slight contrast irregularity
may also appear. A normal operating status can be regained by suspending use for some time. It
should be noted that this phenomenon does not adversely affect performance reliability.
To minimize the performance degradation of the LCD modules resulting from destruction
caused by static electricity etc., exercise care to avoid holding the following sections whenhandling the modules.
- Exposed area of the printed circuit board.
- Terminal electrode sections.

(1) If solder flux is used, be sure to remove any remaining flux after finishing the soldering process.
(This does not apply in the case of a non-halogen type of flux.) It is recommended that yourprotect the LCD surface with a cover during the soldering process to prevent any damage due tothe flux sparks.
(2) When soldering a backlight panel and PCB, the panel and PCB should not be detached morethan 3 times. The temperature determines this number and time conditions as mentioned in theabove table, although there may be some variance depending on the actual temperature of thesoldering iron.

Logic Technologies

Part Number : LT170410-2WHC

Issue Date : 31.07.2019

Version : 1.1(3) When removing a backlight panel from the PCB, ensure the solder has completely melted,
otherwise the solder pads on the backlight panel and/or PCB may be damaged.



OPERATION CAUTION(1) It is recommended to drive LCDs within their specified voltage limit since the higher voltage
than the upper limit shortens the LCD life. An electrochemical reaction due to direct current causes the
LCD to deteriorate. Therefore, avoid the use of direct current drive.
(2) Response time will be extremely delayed at lower temperatures than the operating temperature
range. At higher temperatures LCD’s will experience a dark color. However those phenomena do notmean a malfunction or the LCD’s. Once the LCDs are returned to the specified operating temperature
range, the response time and colouration should return to the normal state.
(3) If the display area is physically pressed hard during it’s operation, some pixels may beabnormally displayed, but should return to their normal condition after resetting the LCM.
(4) Moisture sitting on the LCM terminals is a cause for an electro-chemical reaction resulting in aterminal open circuit. Usage under the relative condition of 40 °C, 50%RH or less is therefore required.



SAFETY(1) It is recommended to crush any damaged or unnecessary LCDs into pieces and wash off theliquid crystal by using solvents such as acetone and ethanol, which should then be burned up
later.
(2) When any liquid crystal has leaked out of a damaged glass cell and comes in contact with skin,please wash it off well with soap and water.



RETURNING PRODUCTS UNDER WARRANTY

No warranty can be granted if the precautions stated above have been disregarded. The typicalexamples of violations are:
- Broken LCD glass.
