🔹Welcome to Lecturelia! In this video — Vector Scan Display (Random Scan Display) | বাংলা টিউটোরিয়াল — we’ll learn how Vector Scan Displays work, how they differ from raster displays, and why they’re also known as Random Scan Displays. Everything is explained clearly in Bangla for easy understanding. 🎯 What you will learn in this video: 0:00 – Introduction 0:28 – Why We Need Vector Scan Display? 3:48 – Architecture 8:23 – Other Name of Vector Scan Display 8:32 – Refreshing Process (How the Screen Maintains the Glow) 10:25 – Advantages 11:08 – Disadvantages 11:18 – Conclusion This lesson is ideal for CSE students, graphics learners, and beginners who want to understand the core concepts of display systems in Computer Graphics. 👉 Watch the previous parts of the series to build a solid foundation: Part-2.1: Cathode Ray Tube (CRT) Part-1.3: Hardware and Software of Computer Graphics 📢 Subscribe for more: 👉    / @lecturelia   👇 Follow us for updates: 📘 Facebook:   / lecturelia   📷 Instagram:   / nomaneeium   🔗 Website: Not available right now 👉 Our completed courses ► Artificial Intelligence -    • Artificial Intelligence (AI) Bangla Tutori...   ► Operating System -    • Operating System (OS) Bangla Tutorial (কমপ...   ► Algorithms -    • Algorithms Bangla Tutorial (কমপ্লিট কোর্স)   ► Compiler Design -    • Compiler Design Bangla Tutorial (কমপ্লিট ক...   ► Computer Graphics -    • Computer Graphics Bangla Tutorial   ► Microprocessor 8085 -    • Microprocessor Bangla Tutorial (কমপ্লিট কো...   ► Theory of Computing -    • Automata Theory Bangla Tutorial (কমপ্লিট ক...   ► Software Engineering -    • Software Engineering Bangla Tutorial   ► Data Communication -    • Data Communication Bangla Tutorial (Behrou...   ► Artificial Neural Network -    • Artificial Neural Network Bangla Tutorial   ► Evolutionary Computation -    • Genetic Algorithm Bangla Tutorial  (কমপ্লি...   Vector Scan Display In previous post we saw how CRT works, but now question arises that how can we print/display point, line and character on screen. This can be answered using vector scan display. To plot/print/display a point, line and character we need to deflect and move the beam of electrons in a desired part of screen, that’s what we do in vector scan display using Display controller unit and Display buffer memory mentioned in above diagram. In vector scan display we do not scan the entire screen instead we just focus on the part/portion of screen where the points and lines need to be displayed. Display Buffer Memory contains very important information which is that commands. Commands to plot a point, line and character’s on screen. For example, if we want to plot a point, then coordinates of that point would be mentioned. Similarly for a line the coordinates of end points of line will be mentioned. Now as Display controller is in contact to display buffer memory, So the controller try to read and interpret the commands mentioned in buffer and accordingly sends signal to the deflection circuitry of CRT to display/print the things on screen. What ever you display will not remain there forever, its glow degrades. Hence we need to again execute the same sequence of commands in order to maintain the displayed points and lines. The rate at which it should be performed is 30-60 times per sec. #ComputerGraphics #BanglaTutorial #Lecturelia #CSETutorial #ComputerGraphicsBangla #VectorScanDisplay #RandomScanDisplay #DisplayDevices #GraphicsLecture #ComputerScienceBangla #EngineeringStudents #BanglaLearning
