摘要： A color cathode ray tube (CRT) includes a multi-beam electron gun (10) capable of operating in two or more modes for use as either a television receiver display or as a high resolution video monitor. The electron gun (10) directs a plurality of electron beams (60b, 60g, 60r; 62b, 62g, 62r) onto the CRT's display screen with the electron beams arranged in two or more groups. In one group of electron beams (62b, 62g, 62r), the beam forming portion of the electron gun, i.e., its G1 screen (22) and G2 control grids (24), provides small diameter electron beams having reduced spot size on the CRT's display screen for high video image resolution when used as a monitor for graphics and/or character display. In another group of electron beams (60b, 60g, 60r), the beam forming portion of the electron gun (10) provides electron beams having a larger diameter and current for increased video image brightness when used as a television receiver.

摘要： A multi-beam electron gun for a color cathode ray tube (CRT) includes a plurality of vertically spaced, horizontal inline beams, where each inline array of beams provides the three primary colors of red, green and blue and adjacent inline beam arrays simultaneously trace adjacent horizontal scan lines on the color CRT's display screen. The beams in each horizontal inline array of beams are focused on a common spot on the display screen, with the three beams deflected across the screen in unison. Each inline array of beams is modulated in accordance with that portion of the video image which they form allowing adjacent, vertically spaced inline arrays to write different video image information on the screen in simultaneously forming adjacent portions of the color video image. In the beam-forming region of the electron gun, a charged grid includes an array of apertures including at least upper and lower horizontally aligned apertures for passing inline arrays of beams. Vertical spacing between each of the upper and lower apertures is given by S V and horizontal spacing between vertically aligned groups of apertures is given by S H , where ¹/₂₀ S H ≦ S V ≦ ¹/₂ S H . Simultaneously providing color video image information on more than one horizontal scan line allows for a reduction in horizontal scan frequency and associated magnetic deflection yoke operating criteria, and also increases beam dwell time on the screen's phosphor elements allowing for a reduction in individual beam current without sacrificing video image brightness while improving video image resolution.

摘要： An electron gun (51) for a color cathode ray tube (CRT) (50) includes a cathode (KG, KR, KB) a low voltage beam forming region (74) (BFR), and a hig voltage deflection focus lens (G5) disposed in the beam deflection region of the CRT's magnetic deflection yoke (58) for simultaneous and coincident focusing and deflection of the electron beams on the CRT's display screen (54). The deflection lens includes a first focus electrode either in the form of a cylindrical metal grid or a conductive coating disposed on the inner surface of the CRT's neck portion (68b) and extending into the magnetic deflection field. The deflection lens further includes a second focus electrode either in the form of a conductive coating or a frusto-conical metallic grid disposed on or immediately adjacent to the inner surface of the CRT's funnel portion intermediate the magnetic deflection yoke and the CRT's display screen. By positioning the electron gun's deflection focus lens within the deflection field, the deflection center of the electron beams is disposed within the focal point of the focus lens permitting the focus lens to operate as a deflection lens to not only focus the beam, but also increase beam deflection sensitivity.
