Easyquick 3.97-inch LCD Module is engineered for compact devices that require a balance between visual clarity, power efficiency, and stable system integration. Designed around a 480×800 TFT resolution, this 3.97-inch LCD Module is positioned for LCD division applications where screen size, cost control, and long-term reliability all matter.
Visual Performance and Viewing Experience
The 3.97-inch LCD Module features a TFT display with 16.7 million colors, ensuring smooth color gradation and precise UI display. Such a high level of color depth enables detailed icons, text, and graphics on a small screen.
Main Advantages
- Resolution: 480×800 pixels, ideal for vertical or tight screen formats
- Full viewing angle design maintains image clarity from any direction.
- Adequate contrast and brightness in indoor and semi-controlled lighting conditions
- Uniform backlighting structure to suppress edge shadowing
For handheld and embedded systems, the 3.97-inch form factor enables the design of handheld devices that are more ergonomic and still have a usable display.
Electrical Performance & System Integration
It is controlled by an AXS15260D-S1 controller IC, which is selected due to the stability of signal processing and compatibility with common control systems. The module features an MIPI 2-lane interface, which ensures efficient data transfer at a high speed while maintaining simplicity of wiring.
From the power perspective, the module consumes power of about 0.81W. This is useful in power-saving designs, where power management is a priority.
Integration Features
- Fast and reliable data transfer through the 2-lane interface: MIPI
- Low power consumption, suitable for use in portable and always-on devices
- Consistency in electrical parameters for multiple batches to support long-term projects
Easyquick provides technical documentation and interface guidance to ensure smooth mainboard matching during development.
