Shenzhen Brownopto Technology’s newly launched 4.39-inch AMOLED display module (Model BR439102-A1) is designed for compact smart devices, combining high contrast, ultra-thin body, and low power consumption. It serves as an ideal solution for smart voice recorders, portable audio devices, and small home appliance displays.
Core Advantages
1.Outstanding Display Performance
High Definition Resolution: 1210×568 pixels, with a pixel pitch of 83.4μm, delivering clear and sharp details.
100,000:1 ultra-high contrast ratio & 100% NTSC color gamut (measured values), remaining clearly visible under strong light.
600 nits typical brightness, supports full viewing angle (85°×4 directions), with no blind spots.
2.Ultra-Low Power Consumption Design
MIPI 2 Lane interface + LTPS low-temperature polysilicon technology, reduces power consumption by 30% compared to traditional LCDs, extending battery life.
Wide voltage support (VDDIO: 1.65~1.98V | VCI: 2.65~3.6V), compatible with various low-power master controls.
3.Compact and Robust Structure
Ultra-thin design: Module thickness of only 0.75mm, saving internal space in devices.
Industrial-grade reliability: Passes high and low temperature storage tests (-40℃~80℃) and continuous operation tests (70℃/-30℃) according to IEC60068 standards, resistant to vibration and impact.
Integrated Touch Functionality
On-Cell touch control (Touch IC: CST3530), supports 10Tx/20Rx channels, responsive and tailored to smart interaction needs.
Technical Certification
Compliant with RoHS 2.0 environmental standards, ESD protection up to ±8kV (air discharge) / ±4kV (contact discharge).
Provides complete optical/electrical/mechanical specification books (including 3D drawings), supporting rapid integration and development.
