HDSM-281H Application Field and Working Principle
The HDSM-281H is a part of the modular display products from Optoelectronic Inc, which is in the segment of display modules - LED character and numeric. It is a very high performance and general purpose display module which includes inbuilt decimal points, seven dual pointer segments, annunciator and circular multi-purpose electrodes.Features
This module has a real-time display capability with no additional electrical components. It also has an extremely fast scan rate and an optimized power supply voltage range of +6V to +12V.It has an integrated logic circuit which is designed to support parallel mode operation. It also supports two types of shift register modes, shift REG FA and RESET BC. This logic circuit is combined with the driving IC to achieve 4 display functions.The module includes a total of 36 LED segments: 7 circular electrodes, 27 characters composed of 7 dual pointer segments and annunciator, and also has a clear display lens that maximizes contrast and visibility of the display characters.Operating Principle
The operation of the HDSM-281H module is relatively straightforward and relies on logic circuits, LEDs and an IC driver.The logic circuit of the HDSM-281H is designed to support two different modes: parallel mode and shift register mode. In the parallel mode, all LEDs are turned on or off with their corresponding logic levels, while in the shift register mode, all LEDs are turned on or off with their corresponding shift register levels.The LEDs of the HDSM-281H are controlled by its integrated IC driver, which receives data via the logic circuit. The IC drivers convert the logic signal received from the logic circuit into signals compatible with the LEDs. The drivers are able to rapidly scan the logic levels from the logic circuit and instantaneously turn on or off the LEDs accordingly.Depending upon the requirement, the HDSM-281H can easily display characters and numbers, as well as symbols. The annunciator of the module helps to show signs and signals, allowing the user to precisely identify which display was meant to be activated.Applications
The HDSM-281H is suitable for various applications such as temperature, time and motion monitors, and indicators for numerical measurement. The module is also applicable in clocks, vending and pricing machines, as well as control panels.Its compact size, low power and wide operating temperature range make it a suitable choice for systems that need to be small, reliable and fast.The HDSM-281H is a highly versatile LED character and numeric display module that provides real-time display capabilities with no additional electrical components. It is optimized for parallel and shift register modes, requires low power and has an optimized voltage operating range between +6V and +12V. The module has 36 LED segments and can easily display characters and symbols, as well as annunciators for signs and signals. It is suitable for a wide range of applications that require reliable and fast display systems.The specific data is subject to PDF, and the above content is for reference
