Video display terminals: Overview, definition, and example
What are video display terminals?
A video display terminal (VDT) is an electronic device used to display information from a computer or other data processing systems. Commonly referred to as a "monitor" or "screen," VDTs are used in various industries, such as business, healthcare, and education, for tasks ranging from data entry to graphical analysis. A VDT typically consists of a screen (CRT, LED, or LCD), a keyboard, and a system unit (either integrated or separate), and it serves as the interface through which users interact with the computer system.
Video display terminals are crucial in modern workplaces where employees use computers for tasks such as document creation, data analysis, design, and communication. The term "VDT" was more commonly used in the past but is still relevant in discussions about ergonomics, workplace health, and the effects of prolonged screen exposure.
Why are video display terminals important?
Video display terminals are important because they serve as the primary means of interacting with digital systems. Whether for work, education, or personal use, VDTs allow users to input commands and view outputs from computers, making them essential tools in today's technological landscape.
However, the increased use of VDTs has also raised concerns about potential health effects, such as eye strain, headaches, and musculoskeletal issues caused by poor posture or prolonged use. As a result, understanding proper ergonomics and using VDTs with proper adjustments is critical for maintaining worker health and productivity.
Understanding video display terminals through an example
Imagine an office worker, John, who spends most of his day entering data into a computer system using a VDT. His VDT consists of a flat-screen monitor, keyboard, and mouse. John uses the VDT to access spreadsheets, input data, and generate reports. The monitor displays all the information he needs to complete his tasks, and the keyboard allows him to interact with the computer.
In another example, a graphic designer uses a video display terminal to create digital artwork. The designer's VDT includes a high-resolution monitor, which allows for precise color and detail control while designing. The designer may also use specialized software and accessories like a stylus or tablet to interact with the VDT for a more hands-on creative process.
An example of a video display terminal clause
Here’s how a video display terminal clause might look in an office policy or safety manual:
“Employees who regularly use video display terminals (VDTs) are required to take breaks every [insert number] minutes to prevent eye strain and fatigue. The company will provide ergonomic workstations, including adjustable chairs, proper lighting, and screen positioning, to reduce the risk of musculoskeletal problems. Employees should also ensure that VDTs are set up to avoid glare and ensure comfortable viewing angles.”
Conclusion
Video display terminals are essential tools for interacting with computers and digital systems in today’s workplace. They enable workers to input, process, and view data, making them critical for a wide range of tasks across industries. As the use of VDTs continues to grow, understanding how to use them effectively and ergonomically is important for maintaining both productivity and employee health.
