Ultra-Compact, High-Performance TFT LCD for Space-Constrained Embedded Designs
Saef Technology Limited introduces the SFTO114JY-7422AN, a 1.14-inch TFT LCD module engineered for applications where size, power efficiency, and visual clarity are critical. With a 135×240 resolution, 400 cd/m² brightness, and an ultra-compact footprint of 17.6mm × 31.0mm, this display is ideal for wearable devices, portable medical monitors, IoT dashboards, handheld instruments, and smart home interfaces.
Optimized for Low-Power & High-Integration Designs:
Efficient SPI Interface: The 4-line SPI interface minimizes pin count and simplifies PCB layout, making it ideal for microcontroller-based systems with limited I/O.
High Brightness & Contrast: At 400 cd/m² and 800:1 contrast ratio, this display ensures excellent readability in both indoor and outdoor-adjacent environments.
Wide Temperature Operation: Certified for -20°C to +70°C operation, suitable for devices exposed to varying environmental conditions.
Low Power Profile: Consumes only 8mA typical during operation and as low as 15µA in sleep mode, extending battery life in portable applications.
Technical Specifications for Engineering Evaluation:
Active Area: 14.864mm × 24.912mm
Pixel Pitch: 0.1101mm (H) × 0.1038mm (V)
Supply Voltage: VDD = 2.4V–3.3V, VDDIO = 1.65V–3.3V
Backlight Voltage: 2.9V–3.1V (typical 3.0V)
Operating Life: 30,000 hours typical
Compliance: RoHS, REACH, ISO9001:2015, ISO14001:2015
