Abstract (en)
The electron gun assembly (64) of a color cathode ray tube apparatus (50) comprises a cathode, and a group of electrodes which jointly form at least one electron lens. The power of this electron lens changes in synchronism with the deflection of electron beams at different change rates during one scanning period.
