Note:
*1. This rating applies to all parts of the module. And should not be exceeded.
*2. The operating temperature only guarantees operation of the circuit. The contrast, response speed,
and the other specification related to electro-optical display quality is determined at the room temperature, T OP =25 ℃
*3. Any Stresses exceeding the Absolute Maximum Ratings may cause substantial damage to the device. Functional
operation of this device at other conditions beyond those listed in the specification is not implied and prolonged
exposure to extreme conditions may affect device reliability.

9 . Assemble Precaution
安装注意事项
1. Customer front panel opening and thickness for
TOPWAY display module should be fit for its assembling
and sealing.
The suggested assemble gap(A) should be about
0.3~0.5mm on each side.
The suggested front panel thickness(B) should be
about 1.5~4.0mm.
客户面板开窗及厚度应适合 TOPWAY 显示模块的安装及
密封 .
2. A silicon sealing ring ships with TOPWAY display
module. It should be in place before assembling to the
front panel.
TOPWAY 显示模块上的硅胶密封圈在安装时确保嵌入到
位 .
3. It should fix the TOPWAY display module into the front
panel with two steps.
Pre-fixing: Slightly tighten the screws on beam clamp
in sequence as picture on the right side.
Final-fixing: Tighten the fixing screws on beam clamp
in sequence as well with twist torque about 4~6kg.cm
(*1) . and put the beam clamp straight.
Note:
*1. Over tightening might damage the shell and cause bad sealing
result.
应分两步将 TOPWAY 显示模块固定在面板上 .
1), 并注意卡扣置正无歪斜 .
注 :
*1. 过度拧紧可能会损坏外壳和影响密封效果 .
4. It is strongly suggested to check the seal balancing of the
four-side of the TOPWAY display module.
The suggested after assemble sealed gap(C) should
be about 0.8~1.2mm.
需注意检查 TOPWAY 显示模块四周在安装后保证平衡密
封 .
5. Others:
Never hot plug the device! Power off the device before connect or disconnect the display
module.
Don't forget to remove the cover protective film for normal operation.
