0.49 Inch​ OLED Display 64*32 Dots Product Introduction

0.49-inch OLED products are small display screens widely used in various smart devices and instruments due to their ultra-thin, low-power, high contrast, and wide viewing angle characteristics. A 0.49-inch OLED display typically has a 64x32 pixel dot matrix, capable of displaying white fonts, driven by an SSD1315 controller, supports I2C serial interface, and operates at 2.8V voltage. This type of display screen, due to the self luminous characteristics of OLED, does not require backlighting, thus having the advantages of ultra-thin body design and low power consumption. Their working temperature range is wide, from -40 ℃ to 85 ℃, and they are suitable for various environmental conditions. In addition, the 0.49-inch OLED display screen adopts FPC connection method, which facilitates direct soldering to the PCB without the need for connectors.

0.49-inch OLED products are highly suitable for devices with strict space requirements due to their compact size and high resolution. They are widely used in smart watches, health monitoring devices, small display screens for industrial control systems, portable game consoles, and other occasions that require small and efficient display screens. 0.49-inch OLED products have become one of the preferred solutions for modern small displays due to their unique technological advantages and wide application potential. With the maturity of technology and the expansion of the market, we can expect such products to play a more important role in future smart and electronic devices.
