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.

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.

## **Structure and Area Definition, RTP housing design guide** 

**Area-(A): Active area.** The area guarantees a touch  panel operation with the following characteristics when pressed. 

( I ) Operation Force      ( II ) Electrical    ( III ) Pen Hitting Durability   ( IV ) Pen  Sliding Durability 

**Area-(B): Operation Non-Guaranteed Area.** The area does not guarantee the operation of touch panel and its function. When this area is pressed, touch panel shows degradation of its performance and durability such as a pen sliding durability becomes about one-tenth compared with the active area (Area- (A) as guaranteed area) and its operation force requires about double. This area is defined about 0.5 mm outside the boundary of active area.

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

**Area-(C): Pressing Prohibited Area** . The area is prohibited pressing because the excessive load will damage transparent electrode and touch panel function. This area is about 0.5mm outside from the boundary of Area-(B)” the operation non-guaranteed area” 

**Area-(D) : Non-Active area (Frame).** The area does not activate even if pressed. 

Note: In order to prevent unusual performance degradation and malfunction of touch panel, please check the design of bezel and  touch panel installation methods after surely confirming the Installing and Assembling as below: 

- 1) Do not give excessive strain to the product 

- 2) Tail cable is connected to the body by heat-seal (thermal pressure) method. So, do not apply excessive forces to the cable. 

   - 【Inhibition】 

Do not add an excessive force to a FPC (Flex tail) that makes peeling off of the FPC from the product as the manner shown in the following figures: 

Do not adhere or mount any additional film or plate on the FPC as shown in below, because such additional goods apply a stress on the tip of FPC and it may tear off the root of FPC from touch panel. 

- 3) The transparent touch panel has air groove. Therefore please design the bezel structure to prevent any liquid or any fine particles. 

- 4) Please provide 0.2mm-0.5mm gap between touch panel and bezel when design the case in order to prevent the any force on the surface of the touch panel.

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

- 5) We recommend that bezel’s opening edge covers the boundary of the active area when design the case in order to prevent an operation at outside of the active area and may cause serious damage to the transparent electrode. 

- 6) a. When design assembly unit, please add  the gasket/cushion (C) outside area of portion (A) as shown in below to avoid any pressing on the portion (A). The area (B) shall be free from burr. The gasket/cushion material at the part (C) should not be exceeded to inside of the boundary of portion (A). 

Please do not make the following mistake:

b. Since ITO film and glass are not eliminated at the edge, therefore please don’t design any conductive material touching the edge of touch panel. 

【Inhibition】 

To prevent giving distortion to the ITO film of the product and peeling off of the film from the product, do not put any adhesive on the film adhered to the case. 

- 7) When designing the case to mount touch panel, a clearance of 0.2-0.3mm between touch panel and inside boundary of case should be considered. 

Meanwhile, in order to avoid touch panel any  failure for extra wrap tail, please take care of keeping clearance of 2.0min.between tail portion and inside boundary of case when the touch panel is built into case. 

- 8) Please keep your case flat in order to prevent touching with T/P directly, which may seriously damage the transparent electrode. 

- 9) Wipe off the stains on the product by using soft cloth moistened with ethanol. Be careful do not to allow ethanol soaking into the joint of upper film and bottom glass. It may otherwise cause peeling off and defective operation. 

   - 【Inhibition】 

Do not use any organic solvent or detergent other than ethanol. 

- 10) The corners of the product are not chamfered. When positioning or fixing the product on the case, we suggest that you would provide an R part on the corner of the case so that no load will apply to the corners of the touch panel.

## 【Inhibition】 

Do not press the film of the product when this product is built into a set. 

- 11) When customer asks to put protection film on the touch panel, please confirm it will not affect the performance of touch panel. Some changes may arise in the characteristics of this product by adding such protection film such as operation, cosmetic, etc.. However, those changes are out of our guarantee. 

   - Even when adding a protection film with adhesion material by company based on the request from customer, it may affect the performance of touch panel such as operation, cosmetic, etc. However, those changes are out of our guarantee. 

- 12) When this product is mounted on the LCD or other display by using a double-sided tape etc., put an enough pressure onto the non-active area (Frame) of a touch panel so that neither exfoliation nor gap may take place between a touch panel and LCD or other target. When assembling, please apply pressure equally onto the corner part and four sides of a touch panel. 

**Area-(B) + Area-(C)** ： **Sensitive area.** Area–(B) and area-(C) are both sensitive areas. There is 

a clearance between top and bottom contact side in these areas. Hard pressing will cause transparent electrode crack and malfunction of touch panel. Please take fully consideration about this sensitive area when designing the case to prevent user touch this area. 

Note: Please apply a layer of gasket cushion around bezel before assembling touch panel. The gasket cushion should be out side of viewable area at least 0.2mm from the boundary of viewable area: 

① If bezel’s opening is bigger than active area’s size, the user could touch sensitive area and may damage the touch panel; 

② If bezel’s opening is smaller than active area’s size, ITO transparent electrode will not be damaged when sliding on the edge of bezel’s opening because sensitive area is covered by bezel around. But gasket’s thickness will be applied when bezel’s edge  enters the active area. The gasket’s thickness should keep 0.2~0.3mm gap between bezel and panel.

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. 

   - (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.

## 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.

- Exposed area of the printed circuit board. 

- Terminal electrode sections. 

## 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 

32/33 

Logic Technologies                  Part Number : LT161010-2NHR                  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.
