Display Screen Core Introduction
The VA liquid crystal molecules in this module are in a vertical alignment state when not powered, and will tilt with the voltage change after being powered, thereby controlling the amount of light passing through to achieve imaging. The low working voltage of 3.5V meets the power supply requirements of most small electronic devices, and the energy consumption control is reasonable.
Key Features
- Negative display mode with dark background and light content
- High contrast ratio (typically above 3000:1) for excellent visibility
- Wide viewing angles with minimal color shift
- Customizable screen size, display area, and interface options
- Includes liquid crystal panels, driving ICs, and FPC flexible circuit boards
- Optional white LED backlight for low-light environments
- Wide operating temperature range (-30℃ to 85℃)
Performance Considerations
Due to the characteristics of VA liquid crystal technology, its response time is slower compared to TN and IPS panels. When displaying high-speed dynamic images, it may cause slight ghosting. Therefore, it is more suitable for static or low-speed changing information display rather than high-dynamic scenes.
