Flashcards

DVST Merits/Demerits

DVST (Direct-View Storage Tube) has advantages in image persistence, high resolution, and cost-effectiveness. However, it has disadvantages related to resolution, refresh rate limitations, and pixel degradation.

Raster vs. Random Scan

Raster displays use a pixel-by-pixel approach to generate images, while random scan displays (vector graphics) generate images based on lines. Raster is for images, random scan is for lines/shapes.

Passive vs. Active Matrix LCD

Passive matrix LCDs use less power but have slower response times. Active matrix LCDs offer faster response times and better image quality but consume more power.

DDA Algorithm Disadvantage

The Digital Differential Analyzer (DDA) line algorithm has an inaccuracy stemming from using floating-point arithmetic, that can accumulate over a line; this means it might generate slight deviations from the intended coordinates along longer or complex lines.
