摘要： The present invention relates to electronic technology field, and more particularly to CRT and projection system. A low power laser CRT based on parallel flow electron gun comprises a vacuum tube, a laser panel provided at one end of the vacuum tube and an electron gun provided at the opposing end. The electron gun adopts a parallel flow electron gun, wherein the parallel flow electron gun comprises a negative electrode, a G1 electrode and a control electrode, wherein the control electrode is connected to an electron beam current control system. The electron gun of the present invention adopts parallel flow electron gun to emit electron beam, so that the laser panel has even current density distribution so as to average the power consumption of laser panel to reduce the energy that is converted to heat.
