HDSP-H3G3 Application Field and Working Principle

HDSP-H3G3 is a LED character and numeric display module developed by Hewlett-Packard Co. The module, which was released in 1983, was designed to provide LCD and LED display features to computers and other electronic devices. It uses a single board design which integrates all the components needed to create a complete display panel. The HDSP-H3G3 consists of four rows and five columns of LEDs with a red, green, and blue (RGB) color. With this combination of LEDs, the user can create a wide range of colors and tones. The display module also has a 4 row by 16 column multiplexer that allows for the creation of complex patterns and designs. The HDSP-H3G3 has the ability to control the voltage and current of the LEDs, allowing for precise dimming and color control. Additionally, the module has a current-scaling feature which enables it to reduce the brightness and power consumption of the display when desired. The module is connected to the main computer system via a parallel port interface and can be programmed to display a variety of items such as text and graphics. The HDSP-H3G3 supports a range of communication systems including USART (Universal Serial Asynchronous Receiver Transmitter), SPI (Serial Peripheral Interface), and EPP (Enhanced Parallel Port) protocols. The working principle of the HDSP-H3G3 can be broken down into the two separate components of illumination and control. The illumination component is responsible for the generation of light that illuminates the LEDs. This is achieved by providing a current to the WSAN (White, Red, Green and Blue) transistor array that is connected to the display module. The control component of the module is responsible for the processing and interpretation of the data that is sent to the module. It is also capable of providing support functions such as error detection and recovery, time synchronization, and multiplexing of the WSAN signals. The HDSP-H3G3 is ideally suited for applications where a low power consumption and high display resolution are necessary. As a result, it is commonly used in handheld devices such as mobile phones, personal digital assistants, and calculators. It is also used in many other industries including medical applications, military applications, and point-of-sale display systems. In conclusion, the HDSP-H3G3 provides an efficient and cost-effective solution for many applications that require a low power consumption and high resolution display. Its versatility makes it suitable for a wide range of applications, from small handheld devices to large scale displays.
