The 1.9-inch TFT LCD module is a compact, high-brightness display solution designed for applications that demand clear visibility, responsive performance, and a small footprint. With a resolution of 170(RGB) × 320 pixels and a transmissive TFT structure, it offers sharp image rendering and smooth color transitions ideal for portable devices, wearables, and compact control systems.
Featuring an all-angle viewing capability (All O’Clock), the display maintains excellent readability and consistent image quality from any direction. It boasts a surface luminance of 750 cd/m² and a high contrast ratio of 1200:1, ensuring vivid visuals even in bright environments.
The active area measures 22.70(H) × 42.72(V) mm within a total viewing area of 23.70(H) × 43.72(V) mm, offering a balanced screen size for space-sensitive designs. With an SPI interface and driven by the ST7789T3-G4-1 controller IC, this module supports streamlined integration and efficient data communication.
Its 30ms response time ensures smooth transitions, while LED backlighting provides reliable illumination with low power consumption. Designed to withstand challenging environments, the module operates across a wide temperature range from -20℃ to 70℃ and can be safely stored between -30℃ and 80℃.
Whether for smart wearables, handheld meters, or industrial interfaces, this display delivers performance and durability in a compact form.
