Note:
*1. This rating applies to all parts of the module. And it should be not 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. Ambient temperature when the backlight is lit (reference value)
*4. 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.

8. Precautions for Use of LCD Modules
Please refer to "LCD-Module-Design-Handling-Precaution.pdf".
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 .
  • 建议每边安装间隙 (A) 约为 0.3 ~0.5mm.
  • 建议面板厚度 (B) 约为 1.5~4.0mm.
  • 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 6~8kg.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 .
  • 预紧 : 将卡扣螺钉按右图所示顺序稍加预紧 .
  • 紧定 : 再次按顺序用 6~8kg.cm 扭力拧紧卡扣螺钉 (*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 1.0~1.5mm.
    需注意检查 TOPWAY 显示模块四周在安装后保证平衡密封 .
  • 建议组装后的密封间隙 (C) 约为 1.0 ~1.5 mm.
  • 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.
    其它 :
  • 视频线禁止带电插拔! 在连接或断开显示模块之前先关闭设备电源 .
  • 使用前请揭去保护膜 .
