The video above you can see our TFT LCD display even in bright sunlight, the screen content remains clearly visible—whether it's data from instruments or the user interface of portable devices, everything is instantly readable. Combined with an IPS full-viewing angle and a 720×1280 resolution, the colors are accurate and the image is clear. Plus, its 8KV anti-static durability ensures consistent brightness, making it suitable for both outdoor work and everyday portable use.

 | Project DevelopmentThe TFT-H040B34 Series represents a defined TFT LCD module development project rather than a generic display category. The project documentation establishes the product model, display size, resolution and engineering specification as the foundation for customer confirmation and production evaluation. |
A compact TFT LCD module must balance display area, resolution and physical integration.
For this project, the defined display format is:
4.0 Inch
with:
480 × 800 Pixels
This configuration provides a portrait-oriented display format for embedded equipment requiring a compact but relatively high-resolution display area.
The project specification is organized around the requirements needed to evaluate a TFT LCD module before production.
These requirements may include:
Display dimensions
Active area
Viewing characteristics
Electrical interface
Driver IC
Backlight
Operating conditions
FPC configuration
Mechanical integration
The final engineering configuration should always be evaluated against the latest project specification.
The published project document contains a customer confirmation section with options for:
Trial Production
and
Mass Production
This is important because it shows the project documentation is structured for product development and production confirmation rather than functioning only as a general catalogue specification.
Hotdisplay can support customized TFT LCD development when a standard display does not directly match the customer's product requirements.
Customization can involve:
Display size
Resolution
FPC
Connector
Interface
Touch panel
Cover glass
Optical bonding
Mechanical integration
Hotdisplay combines engineering with LCD manufacturing and assembly capabilities.
Its published factory information covers processes including COG bonding, FOG bonding, LCD processing, lamination and product testing.
This provides a production path for TFT LCD projects moving from specification and engineering evaluation toward manufacturing.
For OEM and ODM display projects, the technical specification is the foundation for communication between the display manufacturer and the product engineering team.
A structured project document helps define:
What is being developed
Which display configuration is required
Which dimensions must be controlled
Which electrical interface is required
How the module will be evaluated
Whether the project moves to trial or mass production
