ELECTRON GUN FOR COLOR CATHODE RAY TUBE

摘要

PURPOSE: An electron gun is provided to allow for an early stabilization of the luminance and color coordinates of the back raster of the screen by maintaining the gap formed between the first and second electrodes parallel during the thermal expansion. CONSTITUTION: An electron gun comprises a cathode for emitting electron beams toward a phosphor screen; and a first electrode(13), a second electrode(14), a third electrode and a fourth electrode(18) disposed sequentially from the cathode. The connector for applying a voltage to the electrodes includes a voltage conductor portion(19) for applying a voltage and an electrode connector portion(20) for maintaining gaps between the electrodes. The voltage conductor portion and the electrode connector portion are made of materials having different stiffness and thicknesses. The electrode connector portion has a bent portion(21).
