8.1 HANDLING PRECAUTIONS
(1) The module should be assembled into the system firmly by using every mounting hole. Be careful not to twist or bend the module. (2) While assembling or installing modules, it can only be in the clean area. The dust and oil may cause electrical short or damage the polarizer. (3) Use fingerstalls or soft gloves in order to keep display clean during the incoming inspection and assembly process. (4) Do not press or scratch the surface harder than a HB pencil lead on the panel because the polarizer is very soft and easily scratched. (5) If the surface of the polarizer is dirty, please clean it by some absorbent cotton or soft cloth. Do not use Ketone type materials (ex. Acetone), Ethyl alcohol, Toluene, Ethyl acid or Methyl chloride. It might permanently damage the polarizer due to chemical reaction. (6) Wipe off water droplets or oil immediately. Staining and discoloration may occur if they lef t on panel for a long time. (7) If the liquid crystal material leaks from the panel, it should be kept away from the eyes or mouth. In case of contacting with hands, legs or clothes, it must be washed away thoroughly with soap. (8) Protect the module from static electricity, it may cause damage to the C-MOS Gate Array IC. (9) Do not disassemble the module. (10) Do not pull or fold the LED wire. (11) Pins of I/F connector should not be touched directly with bare hands.
8.2 STORAGE PRECAUTIONS
(1) High temperature or humidity may reduce the performance of module. Please store LCD module within the specified storage conditions. (2) It is dangerous that moisture come into or contacted the LCD module, because the moisture may damage LCD module when it is operating. (3) It may reduce the display quality if the ambient temperature is lower than 10 ºC. For example, the response time will become slowly, and the starting voltage of LED will be higher than the room temperature.
8.3 OPERATION PRECAUTIONS
(1) Do not pull the I/F connector in or out while the module is operating. (2) Always follow the correct power on/off sequence when LCD module is connecting and operating. This can prevent the CMOS LSI chips from damage during latch-up. (3) The startup voltage of Backlight is approximately 1000 Volts. It may cause electrical shock while assembling with converter.

Version 0.0 6 November 2014 34 / 47 The copyright belongs to INNOLUX. Any unauthorized use is prohibited. Appendix. SYSTEM COVER DESIGN GUIDANCE 0. Permanent deformation of system cover after reliability test Definition System cover including front and rear cover may deform during reliability test. Permanent deformation of system front and rear cover after reliability test should not interfere with panel. Because it may cause issues such as pooling, abnormal display, white spot, and also cell crack. Note: If the interference can not be avoided, please feel free to contact INX FAE Engineer for collaboration design. We can help to verify and pass risk assessment for customer reference. 1. Design gap A between panel & any components on system rear-cover Definition Gap between panel’s maximum thickness boundary & system’s inner surface components such as wire, cable, extrusion is needed for preventing from backpack or pogo test fail. Because zero gap or interference may cause stress concentration. Issues such as pooling, abnormal display, white spot, and cell crack may occur. Maximum flatness of panel and system rear -cover should be taken into account for gap design. Note: If the interference can not be avoided, please feel free to contact INX FAE Engineer for collaboration design. We can help to verify and pass risk assessment for customer reference.
2 Design gap B1 & B2 between panel & protrusions
Version 0.0 6 November 2014 35 / 47 The copyright belongs to INNOLUX. Any unauthorized use is prohibited. Definition Gap between panel & protrusions is needed t o prevent shock test failure . Because protrusions with small gap may hit panel during the test. Issue such as cell crack, abnormal display may occur. The gap should be large enough to absorb the maximum displacement during the test. Note: If the interference can not be avoided, please feel free to contact INX FAE Engineer for collaboration design. We can help to verify and pass risk assessment for customer reference. 3 Design gap C between system front-cover & panel surface. Definition Gap between system front -cover & panel surface is needed to prevent pooling or glass broken. Zero gap or interference such as burr and warpage from mold frame may cause pooling issue near system font-cover opening edge. This phenomenon is obvious during swing test, hinge test, knock test, or during pooling inspection procedure. To remain sufficient gap, design with system rib higher than maximum panel thickness is recommended. Note: If the inter ference can not be avoided, please feel free to contact INX FAE Engineer for collaboration design. We can help to verify and pass risk assessment for customer reference. 4 Design gap D1 & D2 between system front-cover & PCB Assembly.
Version 0.0 6 November 2014 36 / 47 The copyright belongs to INNOLUX. Any unauthorized use is prohibited. Definition Same as point 2 and 3, but focus on PCBA side.
5 Interference examination of antenna cable and WebCam wire
Antenna cable or WebCam wire should not overlap with panel outline. Because issue such as abnormal display & white spot after backpack test, hinge test, twist test or pogo test may occur. Note: If the interference can not be avoided, please feel free to contact INX FAE Engineer for collaboration design. We can help to verify and pass risk assessment for customer reference.
6 System rear-cover inner surface examination
Definition Burr at logo edge, step s, protrusions or PCB board may cause stress concentration. White spot or glass broken issue may occur during reliability test.
7 Tape/sponge design on system inner surface
Version 0.0 6 November 2014 37 / 47 The copyright belongs to INNOLUX. Any unauthorized use is prohibited. Definition To prevent abnormal display & white spot after scuffing test, hinge test, pogo test, backpack test, tape/sponge should be w ell covered under panel rear-cover. Because tape/sponge in separate location may act as pressure concentration location.
8 Material used for system rear-cover
Definition System rear-cover material with high rigidity is needed to resist deformation during scuffing test, hinge test, pogo test, or backpack test. Abnormal display, white spot, pooling issue may occur if low rigidity material is used. Pooling issue may occur because screw ’s boss positioning for module’s bracket are deformed during open-close test. Solid structure design of system rear -cover may also influence the rigidity of system rear-cover. The deformation of system rear-cover should not caused interference.
9 System base unit design near keyboard and mouse pad
Definition To prevent abnormal display & white spot after scuffing test, hinge test, pogo test, backpack test, sharp edge design in keyboard surface may damage panel during the test. We suggest to use slope edge design, or to reduce the thickness difference of keyboard/mouse pad from the nearby surface.
10 Screw boss height design
Version 0.0 6 November 2014 38 / 47 The copyright belongs to INNOLUX. Any unauthorized use is prohibited. Definition Screw boss height should be designed with respect to the height of bracket bottom surface to panel bottom surface + flatness change of panel itself. Because gap will exist between screw boss and bracket, if the screw boss height is smaller. As result while fastening screw, bracket will deformed and pooling issue may occur.
11 Assembly SOP examination for system front-cover with Hook design
Definition To prevent panel crack during system front -cover assembly process with hook design, it is not recommended to press panel or any location that related directly to the panel.
12 Assembly SOP examination for system front-cover with Double tape design
Definition To prevent panel crack during system front -cover assembly process with double tape design, it is only allowed to give slight pressure (MAX 3 Kgf/50mm2) with large contact area. This can help to distribute the stress and prevent stress concentration. We a lso suggest putting the system on a flat surface stage to prevent unequal stress distribution during the assembly.
13 System front-cover assembly reference with Double tape design
Version 0.0 6 November 2014 39 / 47 The copyright belongs to INNOLUX. Any unauthorized use is prohibited. Definition To prevent system front -cover peeling at double tape contact area, Height difference between system front -cover assembly reference such as wall or components stack (wire, spacer) and double tape top surface must be less than 0.05mm.
14 Touch Application : TP and LCD Module Combination for White Line Prevention
Polarizer edge to LCD AA distance can be derived by “AA~Outline” – “CF Pol~Outline” with respect to INX 2D Outline Drawing on each side.
Version 0.0 6 November 2014 40 / 47 The copyright belongs to INNOLUX. Any unauthorized use is prohibited. Definition For using in Touch Application: to prevent White Line appears between TP and LCD module combination, the maximum inspection angle location must not fall onto LCD polarizer edge, otherwise light line near edge of polarizer will be appear. Parameters such as TP VA to LCD AA distance, TP assembly tolerance, TP Ink printing tolerance, Sponge thickness and tolerance, and Maximum Inspection/Viewing Angle, must be considered with respect to LCD module ’s Polarizer edge location and to lerance. This consideration must be taken at all four edges separately. The goal is to find parameters combination that allow maximum inspection angle falls inside polarizer black margin area. Note: Information for Polarizer edge location and its toleranc e can be derived from INX 2D Outline Drawing (“AA ~Outline“ - “CF Pol~Outline”). Note: Please feel free to contact INX FAE Engineer. By providing value of parameters above on each side, we can help to verify and pass the white line risk assessment for cust omer reference.
15 Color of system front-cover material
Definition To prevent light leakage is seen at system front -cover due to material transparency, we suggest using dark color material (black) for system front-cover design.
16 Inspection spec of gap E between system front-cover to LCD module surface
Version 0.0 6 November 2014 41 / 47 The copyright belongs to INNOLUX. Any unauthorized use is prohibited. Definition To maintain gap E (gap of system front -cover to LCD module) in its inspection spec, especially at location with maximum LCD deformation (center of LCD length), we recommend adding spacer with design gap A smaller or equal to gap E. The allowable spacer mating location is on module metal frame outside LCD Active-Area. Note: If the interference can not be avoided, please feel free to contact INX FAE Engineer for collaboration design. We can help to verify and pass risk assessment for customer reference.
