Abstract: The present invention relates in general to a cathode ray tube, more particularly, to a structure of an electron gun for enhancing resolution of a cathode ray tube. The structure of an electron gun for a cathode ray tube of the invention is effective for enhancing the resolution of the screen without an application of a dynamic voltage.

Abstract: An electron gun for a cathode ray tube is disclosed, which has a simple structure and can prevent the spot on a screen from being degraded. In the electron gun for a cathode ray tube including a cathode that emits electron beams, a first electrode that controls the electron beams emitted from the cathode, a second electrode that accelerates the electron beams emitted from the first electrode, and third to fifth electrodes sequentially arranged in a screen direction to act as pre-focus lenses, the electron gun is characterized in that the third to fifth electrodes have different sized electron beam through holes.

Abstract: An electron gun for a CRT having a cathode for discharging electron beams, a first electrode for controlling the electron beams discharged from the cathode, and a second electrode for accelerating the electron beams having passed the first electrode, third, fourth and fifth electrodes sequentially installed in the direction of a screen and serving as a pre-focus lens, in which an electron beam passing hole of the third electrode, an electron beam passing hole of the fourth electrode and an electron beam passing hole of the fifth electrode have different sizes By controlling the size of the electron beam passing hole of the third the fourth and the fifth electrodes, the divergence angle and the electron beam size are reduced and the spherical aberration is also reduced Accordingly, a degradation of the spot focussed on the screen can be effectively prevented.
