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. 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.

Control and Draw Engine
- TML files, Picture files, ICON files are stored inside FLASH memory area.
They are preloaded to HKT050ATA-C for stand alone interface use.
- Those files are preloaded via USB interface as an USB drive.
- All the interface flow and the touch response are based on the preloaded TML files
- VP variables memory is inside RAM area,
it provides real time access via UART by the HOST or display onto the TFT by TML file.
- Custom Memories are inside FLASH memory area
It can be accessed via UART interface by the HOST.
- Control and Draw Engine executes HOST commands and response respectively
- It also reports the real time Touch Key number to the HOST

5 Precautions of using LCD Modules
Please refer to "LCD-Module-Design-Handling-Precaution.pdf".
6 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 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 .
  • 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 4~6kg.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 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 .
  • 建议组装后的密封间隙 (C) 约为 0.8 ~1.2 mm.
