Description
The YX1784AC63A is a premium 1.78-inch LTPS AMOLED display developed for wearable electronics and portable smart devices that require exceptional image quality, low power consumption, and a compact mechanical design.
Unlike conventional LCD technology, an AMOLED display uses self-emissive pixels that generate their own light without requiring a backlight. This enables true black levels, outstanding contrast, vibrant colors, wider viewing angles, and ultra-fast response times while reducing power consumption, particularly when displaying dark user interfaces.
Featuring a 368 × 448 resolution, RM69090 driver IC, and support for both MIPI and SPI interfaces, the module integrates easily into next-generation wearable products and embedded systems. With a 28.7 × 34.94 mm active area, 30.6 × 37.99 mm LTPS glass outline, and an operating temperature range of -20°C to +70°C, the YX1784AC63A offers an excellent balance of visual performance, reliability, and energy efficiency.
