Product Description
The TOPWAY LMT070DAMFWA-NFD is a 7-inch TFT LCD display module featuring a 1024 × 600 pixel resolution and 16.7 million colors. Designed for embedded systems, industrial equipment, monitoring devices, and custom display applications, it provides convenient video connectivity through both HDMI and VGA interfaces.
The display uses transmissive TFT technology with an RGB vertical stripe pixel configuration and an integrated white LED backlight. Its 1024 × 600 resolution provides a clear graphical display for operating interfaces, system monitoring, multimedia content, and other visual applications.
Unlike conventional TFT modules that require direct connection to a display controller through RGB or SPI signals, this module accepts standard HDMI and VGA video signals from compatible host devices. The manufacturer specifies support for 800 × 600, 1024 × 600, and 1024 × 768 at 60Hz from a PC.
The module also includes a dedicated touch-panel controller connection with USB D+ and D- signals, allowing connection to a compatible touch-panel assembly. The datasheet includes mounting instructions for both capacitive and resistive touch panels; the touch-panel configuration supplied with the product should be verified separately.
Operating from a 12V DC main supply, the LMT070DAMFWA-NFD is suitable for embedded computers, industrial control systems, electronic instruments, and projects requiring a larger display with standard video connectivity.

The 1024 × 600 resolution provides sufficient screen space for graphical interfaces, measurement readings, menus, system status, and multimedia content.
2. HDMI Video Interface
The module includes a standard HDMI input through the K2 terminal.
The HDMI interface receives digital video signals through TMDS data channels and a clock channel. It also includes the necessary DDC communication signals and Hot Plug Detect connection.
The manufacturer specifies support for the following standard HDMI input resolutions from a PC:
| Resolution | Refresh Rate |
|---|---|
| 800 × 600 | 60Hz |
| 1024 × 600 | 60Hz |
| 1024 × 768 | 60Hz |
The HDMI connector also provides a +5V output for the DDC memory.
Important: The manufacturer explicitly states that the HDMI terminal must be properly connected before powering on. Hot-plugging is not allowed according to the datasheet.
3. VGA Video Interface
The module also provides an analog VGA input through the K3 terminal.
The VGA interface includes:
- Red video signal input.
- Green video signal input.
- Blue video signal input.
- Horizontal synchronization (HS).
- Vertical synchronization (VS).
- Signal ground.
- SDA and SCL signals.
Supported VGA resolutions from a PC are:
| Resolution | Refresh Rate |
|---|---|
| 800 × 600 | 60Hz |
| 1024 × 600 | 60Hz |
| 1024 × 768 | 60Hz |
Like the HDMI connection, the VGA terminal must be properly connected before powering on. The datasheet does not allow hot-plugging.
4. Touch Panel Controller Interface
The module provides a dedicated K4 terminal for the touch-panel controller.
| Pin | Signal | Description |
|---|---|---|
| 1 | GND | Ground |
| 2 | VCC | 5V DC supply |
| 3 | GND | Ground |
| 4 | D+ | USB Data Positive |
| 5 | D- | USB Data Negative |
| 6–10 | NC | No Connection |
The USB D+ and D- signals provide the touch-controller connection to a compatible host device.
The datasheet includes mounting instructions for:
- CTP: Capacitive Touch Panel.
- RTP: Resistive Touch Panel.
Note: The existence of the touch-controller terminal and mounting instructions does not, by itself, confirm which touch-panel type is fitted to every supplied unit. Verify the actual product configuration before selecting a touch driver or advertising a specific touch technology.
5. Electrical Characteristics
The display uses a 12V DC main supply.
| Parameter | Minimum | Typical | Maximum |
