| Abstract: | The infinite difference method is combined with the neural network technique. It is used to estimate the effects of the electron gun main lens dimension error to the electron beam spots on the screen. Compared with the normal calculation method, this method can save computation time, avoid much complex calculation and save many computer sources. Once the network is well trained, it can predict the effects of the electron gun main lens dimension error to the electron beam spots on the screen in a short time. This method is very useful to the CRT production. |
