What is vector scan display device?

A vector scan display device is a type of display technology that generates images by drawing lines directly on the screen using an electron beam. Unlike raster scan displays, which create images by illuminating pixels in a grid pattern, vector displays render graphics by moving the beam continuously to form shapes and lines. This method allows for smoother curves and sharper images, making vector displays particularly suitable for applications like oscilloscopes and early computer graphics. However, they are less common today, having been largely replaced by raster-based technologies such as LCD and LED displays.
