4.4 inch AMOLED Display Module BR440102-A1 with Touch | 568×1210 MIPI Interface

The 4.40-inch AMOLED module (Model: BR440102-A1) from Shenzhen Brownopto Technology Co., Ltd. is a high-resolution display designed for smart devices, industrial HMIs, and advanced user interfaces. With a sharp resolution of 568 × 1210 pixels and driven by the SD5207 driver IC, this LTPS-based AMOLED panel delivers stunning image quality, deep blacks, and ultra-high contrast. It features a MIPI 2-Lane interface, ensuring fast data transmission and seamless integration with modern SoCs. The module achieves a typical brightness of 600 nit, supports 16.7 million colors, and offers excellent viewing angles (80° in all directions). Built with an integrated touch panel (On-Cell Touch), it's ideal for compact yet powerful interactive applications. Operating reliably from -30°C to +80°C, this display combines performance, durability, and sleek design.
