Write The Properties Of Video Display Devices?
Persistence:- The key difference between phosphorus is its consistency. It determines how long they will manage to emit photons after the electric field is withdrawn. Persistence is characterized as the period the emitted light decays from the screen to one-tenth of its initial brightness. Resolution:- Resolution means the minimum number of points that can be shown without overlapping the CRT The resolution depends on the form of phosphorus, the strength to be reflected, and the concentrating and deflection methods used in the CRT system. Aspect Ratio:- The proportion of horizontal points to lateral points is used to establish equal duration lines on the display in both dimensions. The proportion ratio of 4/5 means that the black line labeled with four dots is also the same width as the diagonal line plotted with five stars.
