Backlight drive conditions :  constant current driving method. 

- The LED driving condition is defined for each LED module (3 LED Serial, 9 LED Parallel). 

- The LED driving condition is defined for total backlight consumption. 

- Forward Voltage adjustment depends on the Forward Current setting. 

- One LED : max IF = 25mA, VF = 3.3V 

- The LED lifetime is estimated data at 25degC operating.

- I defined for whole backlight without driver. F 

- 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.

Contrast ratio (CR) is defined mathematically in Figure 2.<br>Contrast Ratio = Average Surface Luminance with all white pixels (P1, P2, P3, P4, P5)<br>  Average Surface Luminance with all black pixels (P1, P2, P3, P4, P5)<br>      Note 2. Surface luminance is the LCD surface from the surface with all pixels displaying white.<br>      For more information see figure 2.<br>Lv = Average Surface Luminance with all white pixels (P1, P2, P3, P4, P5…)<br>Note 3.

Response time is the time required for the display to transition form white to black (rise time<br>Tr) and from black to white (decay or fall time, Tf). The industry standard test equipment used is the<br>Autronic-Melcher’s Conoscope.<br>Note 5. CIE (x,y) chromaticity. The x,y value is determined by measuring luminance at each test<br>position 1 through 5, then calculating the average value.<br>Note 6. The Viewing angle is the angle at which the contrast ratio is greater than 2. For a TFT<br>module, the contrast ratio is greater than 10. The angles are determined for the horizontal or ‘x’ axis<br>and the vertical or ‘y’ axis with respect to the ‘z’ axis, being the LCD surface reference. Also see<br>figure 3.<br>Note 7. For viewing angle and response time testing, the testing data is based on Autronic-Melcher’s<br>BM-7A.  For the contrast ratio, surface luminance, luminance uniformity and chromaticity (CIE), the<br>test data is based on the industry’s standard SR-3A photo detector.<br>Note 8. For TFT modules, grey scale reversing occurs in the direction of the panel viewing angle.<br>Figure 1.

Notes: 

1. Test samples are applied to one test item. 

2. Sample size for each test item is 2-10pcs. 

3. 

4. (a) In the case of a malfunction caused by ESD damage, if the LCM returns to it’s normal state after resetting, the item is considered to have passed the ESD test. 

   - (b) It is recommended to use an anti-static blower (ioniser) to reduce the electro-static voltage in the working area. 

20/27 

Logic Technologies                  Part Number : LT161010-2NHC                  Issue Date : 02.09.2019 Version : 1.7 

   - (c) When removing the protection film from the LCM panel, peel off the film slowly (more than 1sec) while blowing the ioniser towards the peeling area to minimize ESD. This will reduce the risk of damaging the electrical circuitry. 

5. EL backlights are exempt from the reliability testing with respect to temperature       and humidity. Some defects many occur such as black spots or blemishes due to the inherent chemical reaction of humidity with fluorescent EL. 

6. If it is installed, please use the automatic test mode on the LCM &/or demonstration box when testing. 

##  **INSPECTION CRITERIA** 

This specification is designed to be used as the standard acceptance/rejection criteria for normal LCM products. 

1. Sampling plan. 

The sampling plan according to GB/T 2828.1-2003 / ISO2859-16 1999 and ANSI/ASQC Z1.4 1993, normal level 2 and based on: 

- Major defect: AQL 0.65 

- Minor defect: AQL 1.5 

## 2. Inspection condition 

   - The viewing distance for cosmetic inspection is approximately 30cm with the naked eye, and under an environment of 20-40W light intensity, in all directions, within 45° against a perpendicular line. (Normal temperature 20-25°C and normal humidity 60+/-15 RH.) 

   - Driving voltage - The Vop value from which the most optimal contrast can be obtained near the specified Vop in the specification (within +/-0.5V of the typical value at 25°C.) 

3.   Definition of inspection zone in LCD. Figure 4 

Zone A : active pixel area Zone B : viewing area except Zone A (Zone A + Zone B = Minimum viewing area) Zone C : Outside viewing area (invisible area after assembling A B C into customer’s product. 

Figure 4 inspection zones in an LCD 

Note: As a general rule visual defects in Zone C are permissible when there is no visual effect once assembled into the customer’s product.

## PRECAUTIONS FOR USING LCD MODULES 

## Handing 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 a soft 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 a current flow in a high-humidity environment, accelerate corrosion of the electrodes. 

   - (8) Install the LCD Module by using the mounting holes. When mounting the LCD module ensure it is free of twisting, warping or distortion. In particular, do not forcibly pull or bend the IO cable or the backlight cable. 

   - (9) Do not attempt to disassemble or process 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 other 

- work 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 Precautions 

When storing the LCD modules, avoid exposure to direct sunlight or to the light of fluorescent lamps. Keep the modules in bags (avoid high temperature  high humidity and low temperatures below the stated storage temperature of the LCM specification). 

## 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 when handling the modules.

## USING LCD MODULES 

## Liquid Crystal Display Modules 

LCD is composed of glass and polarizer. Pay attention to the following items when handling. 

(1) Please keep the temperature within specified range for use and storage. Polarization degradation, bubble generation or polarizer peel-off may occur with high temperature and high humidity. 

- (2) Do not touch, push or rub the exposed polarisers with anything harder than an HB pencil lead 

- (glass, tweezers, etc.). 

(3) N-hexane is recommended for cleaning the adhesives used to attach front/rear polarisers and reflectors made of organic substances that may be damaged by chemicals such as acetone, toluene, ethanol and isopropyl alcohol. 

(4) When the display surface becomes dusty, wipe gently with absorbent cotton or other soft material like chamois soaked in petroleum benzene. Do not scrub hard to avoid damaging the display surface. (5) Wipe off saliva or water drops immediately, contact with water over a long period of time may cause deformation or color fading. 

- (6) Avoid contacting oil and fats. 

(7) Condensation on the surface and contact with terminals due to cold will damage, stain or dirty the polarisers. After products are tested at low temperature they must be warmed up in a container before coming is contacting with room temperature air. 

- (8) Do not put or attach anything on the display area to avoid leaving marks on. 

(9) Do not touch the display with bare hands. This will stain the display area and degrade the insulation between the terminals. 

- (10) As glass is fragile. It tends to become chipped during handling especially on the edges. 

- (11) Mounting Method 

The panel of the LCD Module consists of two thin glass plates with polarizes, which easily get damaged. Since the Module is fixed by utilizing fitting holes in the printed circuit board. Extreme care should be taken when handling the LCD Modules. 

- (12) Caution against static charge 

The LCD Module use C-MOS 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. And ground your body, Work/assembly table. And assembly equipment to protect against static electricity.

- (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 your protect the LCD surface with a cover during the soldering process to prevent any damage due to the flux sparks. 

- (2) When soldering a backlight panel and PCB, the panel and PCB should not be detached more than 3 times. The temperature determines this number and time conditions as mentioned in the 

26/27 

Logic Technologies                  Part Number : LT161010-2NHC                  Issue Date : 02.09.2019 Version : 1.7 

above table, although there may be some variance depending on the actual temperature of the soldering iron. 

- (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. 

## Caution for operation 

(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 not mean 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 be abnormally 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 a terminal 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 the liquid 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.
