Description

LA78141 is vertical deflection output IC, Vertical Amp CRT TV Reciever.

A Vertical Deflection Output IC (Integrated Circuit) is an electronic component used in cathode-ray tube (CRT) displays, such as older televisions and computer monitors, to control the vertical movement of the electron beam that draws the images on the screen. These ICs are a vital part of the vertical deflection circuitry, which ensures that the electron beam moves smoothly and accurately from the top to the bottom of the screen to create a complete image.

1. Vertical Deflection: In a CRT display, the electron beam needs to move vertically to scan and draw each line of the image. The Vertical Deflection Output IC is responsible for generating the necessary signals to control the magnetic coils (vertical deflection coils) that move the electron beam vertically.
