Introduction:
When selecting a smart display for embedded systems, industrial HMIs, or automation projects, understanding the model number structure is just as important as knowing the screen size or resolution. Each DWIN display model code carries detailed information about its product line, colour depth, resolution, application grade, size, hardware version, temperature range, touch type, and memory configuration.
To simplify this process, DWIN follows a standardised naming convention for its Smart LCM (Liquid Crystal Module) product line. At first glance, a model number may appear complex—but once you understand the logic behind it, selecting the right display becomes fast and error-free.
In this blog, we will decode the DWIN display model numbering system step by step, starting with a real-world example:
DMG80480T070_15WTR
By breaking down this model code, you will learn how to:
Identify the product line and display type
Understand color depth and resolution
Select the right screen size and application grade
Recognize touch panel options and temperature ratings
Differentiate between hardware versions and memory configurations
This structured approach will help engineers, designers, and buyers confidently choose the most suitable DWIN Smart UART LCD module for their application—without confusion or guesswork.
1. Product Line Code – DM (DWIN Smart LCM Product Line)
In the DWIN model numbering system, the first two characters identify the product line. For the model DMG80480T070_15WTRIOT, the prefix “DM” represents the DWIN Smart LCM (Liquid Crystal Module) product line.
DMG80480T070_15WTRIOT
The DM series is designed for intelligent human–machine interface (HMI) applications, where display control, UI rendering, and communication are handled directly by the module. These displays typically integrate:
A built-in GUI engine
UART serial communication (TTL level)
Onboard flash memory for UI resources
Support for DWIN’s DGUS/DGUS II development environment
2. Color Code – T / G (Display Color Depth)
In the DWIN Smart LCM model number, the color code is represented by one character placed immediately after the product line code. This character defines the color depth of the display, which directly affects image quality, color smoothness, and overall user interface appearance.
For example, in the model DMG80480T070_15WTRIOT, the letter “G” indicates a high color-depth display.
DMG80480T070_15WTR
Color Code Definitions
| Color Code | Color Depth | Description |
|---|---|---|
| T | 65K colors (16-bit) | Suitable for basic graphics, icons, and text-based user interfaces |
| G | 16.7M / 262K colors (18-bit / 24-bit) | Ideal for rich graphics, gradients, photos, and modern UI designs |
T – 65K Color (16-bit)
Uses RGB565 color format
Lower memory and bandwidth requirements
Cost-effective solution
Best for industrial HMIs, simple control panels, and data displays
G – 16.7M / 262K Color (18-bit / 24-bit)

How to Choose the Right Color Code
Choose T (65K color) if your application focuses on stability, readability, and cost efficiency
Choose G (16.7M color) if your project requires a premium user experience and detailed graphics
3. Resolution Code (5 Digits)
In the DWIN Smart LCM model number, the resolution is represented by a 5-digit numeric code. This code directly specifies the horizontal × vertical pixel resolution of the display, determining how much information and graphical detail can be shown on the screen.
DMG80480T070_15WTR
For example, in DMG80480T070_15WTRIOT, the code 80480 means the display resolution is 800 × 480 pixels.
Common DWIN Resolution Codes
| Resolution Code | Pixel Resolution |
|---|---|
| 24240 | 240 × 240 |
| 32240 | 320 × 240 |
| 48270 | 480 × 272 |
| 48320 | 480 × 320 |
| 64360 | 640 × 360 |
| 64480 | 640 × 480 |
| 80480 | 800 × 480 |
| 85480 | 854 × 480 |
| 80600 | 800 × 600 |
| 10600 | 1024 × 600 |
| 10768 | 1024 × 768 |

| 19108 | 1920 × 1080 |
| 19480 | 1920 × 480 |
Why Resolution Matters
Lower resolutions are ideal for simple text, icons, and status displays
Medium resolutions provide a balance between clarity and performance
High resolutions enable detailed graphics, images, and advanced HMI layouts
Choosing the correct resolution ensures:
Clear readability
Smooth UI performance
Optimal memory usage
