Embodiment Construction

[0030] An embodiment of the present invention will be described below with reference to the drawings.

[0031] Such as figure 1 As shown, a color cathode ray tube device as an example of a cathode ray tube device has a vacuum envelope 30 . The vacuum envelope 30 has a glass panel 20 and a funnel 21 integrally sealed with the glass panel 20 . The glass screen 20 has a fluorescent screen 22 formed by three-color fluorescent layers emitting blue, green, and red light on its inner surface. The shadow mask 23 is arranged at a position facing the fluorescent screen 22, and has many electron beam passing holes inside.

[0032] The electron gun member 26 is arranged in the neck 24 of the funnel 21 . The electron gun unit 26 emits three electron beams 25B, 25G and 25R toward the fluorescent screen 22 along the tube axis direction, ie, the Z-axis direction. The three electron beams emitted from the electron gun member 26 are composed of a center beam 25G and a pair of side beams 25B...

Abstract

A resistor (32) for an electron gun member for applying a voltage divided by resistance to an electrode of the electron gun member of the present invention has: an insulating substrate (40, 50, 60) arranged at a predetermined position on the insulating substrate A plurality of first resistance elements (41, 51, 61), and a second resistance element (44, 54, 64) having a predetermined pattern electrically connecting the first resistance elements, further comprising: the first A structure in which the effective wiring length of the second resistive element between one resistive element varies depending on the arrangement position of the second resistive element relative to the first resistive element (43, 54A, 54B, 54C, 71A, 71B , 72A, 72B).

Description

technical field [0001] The present invention relates to a resistor for an electron gun member included in a cathode ray tube and a method for manufacturing the resistor, and more particularly to a resistor for applying a voltage divided by resistance to electrodes included in an electron gun member and a method for manufacturing the resistor. Background technique [0002] In color cathode ray tube devices, in recent years, in order to improve the image quality thereof, a high voltage is increasingly required. Then there is a danger of damage to circuit components due to spark current or discharge noise generated by the discharge in the tube. In such a high-voltage usage environment, resistors for resistively dividing the high voltage supplied to electrodes of the electron gun member are arranged inside the cathode ray tube device in order to prevent discharge and improve image quality. [0003] The conditions required for such resistors for electron gun components are, for ...
