LOW-POWER CONSUMPTION LASER CRT BASED ON LAMINAR GUN AND PROJECTION SYSTEM

摘要

A CRT and a projection system. The CRT is a low-power consumption laser CRT based on a laminar gun, including a vacuum tube. One end of the vacuum tube is provided with a laser panel, and another end of the vacuum tube is provided with an electron gun. The electron gun employs a laminar gun. The laminar gun includes a cathode, a G1 electrode, and a control electrode. The control electrode is connected to an electron beam current control system. Since the electron gun employs a laminar gun to emit an electron beam, the current density of the laser panel has relatively uniform distribution, which evens the power consumption of the laser panel and reduces the energy converted to heat.
