cause the display color change abnormally.

 

-

 

LCD panel is made with glass. Any mechanical shock (e.g. 
dropping from high place) will damage the LCD module.

 

-

 

 

-

 

液晶屏由玻璃制作而成,任何机械碰撞

(

如从高处跌落

)

均有可能损坏液晶显示模块。

 

-

 

Protective film is attached on LCD screen. Be careful when 
peeling off  this protective film, since static electricity may 
be generated.

 

-

 

Polarizer on LCD gets scratched easily. If possible, do not 
remove  LCD  protective  film  until  the  last  step  of 
installation.

 

-

 

When  peeling  off  protective  film  from  LCD,  static  charge 
may  cause  abnormal  display  pattern.  The  symptom  is 
normal, and it will turn back to normal in a short while.

 

-

 

LCD panel has sharp edges, please handle with care.

 

-

 

Never attempt to disassemble or rework LCD module.

 

-

 

If  display  panel  is  damaged  and  liquid  crystal  substance 
leaks  out,  be  sure  not  to  get  any  in  your  mouth,  if  the 
substance  comes  into  contact  with  your  skin  or  clothes 
promptly wash it off using soap and water.

 

7 CTP Mounting Instructions 

7.1 Bezel Mounting (Figure 1)

 

-

 

The  bezel  window  should  be  bigger  than  the  CTP  active 

area. It should be≥0.5mm each side.

 

-

 

Gasket should be installed between the bezel and the CTP 
surface.  
The final gap should be about 0.5~1.0mm.

 

-

 

It  is  recommended  to  provide  an  additional  support 
bracket  for  backside  support  when  necessary  (e.g.  slim 
type  TFT  module  without  mounding  structure).  They 
should  only  provide  appropriate  support  and  keep  the 
module in place.

 

-

 

The  mounting  structure  should  be  strong  enough  to 
prevent  external  uneven  force  or  twist  act  onto  the 
module.

液晶屏表面带有保护膜

揭除保护膜时需要注意可能产

生的静电。

 

-

 

 

-

 

因液晶显示屏表面的偏光片极易划伤,安装完成之前请
尽量不要揭下保护膜。

 

-

 

 

-

 

请缓慢揭除保护膜,在此过程中液晶显示屏上可能会产
生静电线,此为正常情况,可在短时间内消失。

 

-

 

 

-

 

请注意避免被液晶显示屏的边缘割伤。

 

-

 

请不要试图拆卸或改造液晶显示模块。

 

-

 

当液晶显示屏出现破裂

内部液晶液体可能流出

相关

液体不可吞吃

绝对不可接触嘴巴

如接触到皮肤或衣

请使用肥皂与清水彻底清洗

电容触摸屏安装指导

 

7.1

面框安装(附图

1

 

-

 

客户面框窗口应大于

CTP

动作区域,各边离动作区应

0.5mm.

 

-

 

面框与

CTP

面板间应垫有胶垫,其最终间隙约为

0.5

1.0mm.

 

-

 

 

-

 

建议必要时在背面提供附加支架

(

例如无安装结构的薄型

TFT

模块

)

,应仅利用适当支撑以保持模块位置

.

 

 
 
 

-

 

安装结构应具有足够的强度,以防止外部不均匀力或扭
曲力作用到模块上

.

7.2 Surface Mounting (Figure 2)

 

-

 

As  the  CTP  assembling  on  the  countersink  area  with 
double side adhesive. 
The  countersink  area  should  be  flat  and  clean  to  ensure 
the double side adhesive installation result.

 

-

 

The  Bezel  is  recommend  to  keep  a  ga

p  (≥0.3mm  each 

side) around the cover lens for tolerance.

 

-

 

It  is  recommended  to  provide  an  additional  support 
bracket  with  gasket  for  backside  support  when  necessary 
(e.g.    TFT  module  without  mounding  structure).  They 
should  only  provide  appropriate  support  and  keep  the 
module in place.

 

-

 

The  mounting  structure  should  be  strong  enough  to 
prevent external uneven force or twist act onto the module

客户面框应具有使用双面胶粘贴

CTP

的结构沉台面,其

粘贴面要求平整且洁净无污以保证粘贴牢靠

考虑到制作误差,建议面框与

CTP

盖板之间四周留有

0.3mm

间隙
