![]() ![]() The main function of phosphor is to change the energy from electrical to light. The faceplates within the surface can be covered through phosphor crystals. ![]() This plate can be formed by pushing the molten glass into a shape & then melting it. For larger displays, the CRT screen is curved a little. The CRT front side is known as the faceplate and it is flat for up to 100mm×100mm sized screen. The pair of plates which is mainly utilized for horizontal deflection is called an X plate or horizontal deflection plate. The pair of plates that emits the vertical deflection is known as a Y plate or vertical deflecting plate. Once the electron ray leaves the electron gun, then it supplies throughout the two pairs of the deflecting plates. The cathode-ray oscilloscope works with an electrostatic focusing tube. There are two focusing methods on the electron ray-like electrostatic and electromagnetic. Both the anodes like accelerating and pre-accelerating are connected to 1500 volts whereas the focusing electrode can be connected to 500volts The electron ray is focused on electrodes & supplies throughout the two deflection plates & goes finally on to the fluorescent lamp. ![]() This potential can be given to the accelerating or pre-accelerating nodes. The electron flowing throughout the control grid can speed up a high positive potential. It controls the discharged electron intensity from the cathode. For achieving the high electron emission at the normal temperature, then strontium & barium layers can be deposited on the cathode end.Īfter the electrons discharged from the cathode grid are done, it supplies throughout the control grid which is generally a nickel cylinder through a centrally positioned co-axial and the CRT axis. ![]()
