The HDSP-301E is an alphanumeric organic light emitting diode (OLED) display module designed for embedded use. It has 12 0.56" (14.2 mm) tall characters, two single digits and two 3-segment bars. HDSP-301E operates from a wide 3.3V to 7.0V DC voltage range.

The HDSP-301E is a display module suitable for space-constrained applications where visibility is essential. It features high contrast, wide viewing angle, low power consumption and a long operational life making it ideal for cost-sensitive, single-color applications such as commercial or industrial equipment control and verification.

This OLED module has twelve characters, each 0.56” (14.2 mm) tall, and displays numeric, alphabetic and punctuation symbols in one or two lines. The two 3-segment bars on the side of the display indicate either bar graphs/intervals or simply on/off conditions for two of the 12 characters. The display can be utilized for status or alert messages.

The HDSP-301E display is controlled by a serial communications interface (SCI) and can be daisy-chained to up to two other displays, allowing the use of a single SCI to control the entire display. The SCI protocol is proprietary, but is similar to the I2C protocol and runs at a maximum speed of 100KHz.

The HDSP-301E display has several features which make it attractive to the embedded engineer. These features include: ability to daisy-chain up to three displays, 128-65536 byte display buffer, contrast and brightness control, implemented with software commands, analog dimming control, power-saving sleep/wake feature, and an adaptive algorithm to change display brightness according to ambient light.With its slim-line design, wide voltage range and flexibility, the HDSP-301E is a great choice for embedded projects with tight space requirements and budgetary restrictions.

The HDSP-301E is an alphanumeric OLED display module featuring 12 0.56" (14.2 mm) tall characters, two single digits, and two 3-segment bars. It is suitable for small form-factor applications including cost-sensitive single-color applications such as commercial or industrial equipment control and verification. It has a wide voltage range of 3.3V to 7.0V, is controlled by a serial communications interface (SCI), and can be daisy-chained to up to three displays. The display features a 128-65536 byte display buffer, contrast and brightness control, and power-saving sleep/wake feature.
