摘要： The invention includes an apparatus (40, 140) for developing a latent charge image formed on a photoreceptor (36) disposed on an interior surface of a faceplate panel (12). The apparatus (40, 140) comprises a developer tank (42) having a sidewall (44) closed at one end by a bottom portion (46) and at the other end by a panel support (48) having an opening (50) therethrough to provide access to the faceplate panel (12). The back electrode (52) has a potential applied thereto to establish an electrostatic drift field between the back electrode and the photoreceptor (36), which is grounded. Triboelectrically-charged, dry-powdered, light emitting phosphor material, having a charge of the same polarity as the potential applied to the back electrode (52), is injected into the developer tank (42), between the back electrode (52) and the faceplate panel (12). The triboelectrically charged phosphor material is directed toward the photoreceptor (36) on the faceplate panel (12) by the applied electrostatic drift field. Panel skirt sidewall shields (66, 68) are disposed around a peripheral sidewall (18) of the faceplate panel (12) to repel the triboelectrically-charged phosphor material from the panel sidewall (18).

摘要： A dynamic focus voltage generator (21) is provided for a tensioned focus mask (30) of a cathode ray tube (10) of video display. The tensioned focus mask (30) includes spaced apart strands (44) and spaced apart crosswires (46) separated from the strands (44). A synchronizing signal at a horizontal deflection frequency is used for generating a dynamic focus voltage component that varies in accordance with a position of an electron beam on a screen (28) of the cathode ray tube (10). A synchronizing signal at a vertical deflection frequency is used for generating a dynamic focus voltage component that varies in accordance with the position of the electron beam on the screen (28) of the cathode ray tube (10). The time varying voltage components are combined with a direct current voltage component for producing a dynamic focus voltage between the strands (44) and crosswires (46).

摘要： A cathode ray tube (CRT) (1) having a glass envelope (2) is disclosed. The glass envelope is formed of a rectangular faceplate panel (3) and a tubular neck (4) connected thereto by a funnel (5). An electron gun (13) is positioned in the neck for directing electron beams toward the faceplate panel. A yoke (14) is positioned in the neighborhood of the funnel-to-neck junction. The yoke has windings configured to apply a horizontal deflection yoke field and a vertical deflection yoke field to the beams. At least one magnetic field sensor (17) is located near the glass envelope for sensing an ambient magnetic field environment of the CRT. A controller receives a signal from the magnetic field sensor. Register correction coils are mounted in the vicinity of the neck and are dynamically controlled by the controller to shift the beams. Quadrupole coils (16) are applied to the neck and have adjacent poles of alternating polarity such that the resultant magnetic field being dynamically controlled by the controller based on the magnetic field sensor signal moves outer ones of the beams to correct the misconvergence caused by the register correction.

摘要： A color picture tube (10) has a tensioned mask (24) supported by a support frame (28) mounted within said tube. The mask has a significantly lower coefficient of thermal expansion than the frame. Intermediary members (48) are located between the mask and the frame. The intermediary members are of a material similar to that of the mask. Each of the intermediary members is attached to the frame at a single location (50), and the mask is attached to edges of the intermediary members. Further included are guides (56, 58) for holding the intermediary members to the frame while permitting expansion of the frame relative to the intermediary members.

摘要： A color picture tube (10) has a tensioned mask (24) supported by a support frame (50) mounted within the tube. The mask has a significantly lower coefficient of thermal expansion than the frame. The mask has an active apertured portion (40) formed by a plurality of parallel vertically extending strands (42), through which electron beams pass during operation of the tube, and two opposite side border portions (46, 48) outside the active apertured portion. The two opposite side border portions have tie bars (49) that extend between the vertical strands of the mask. The tie bars accommodate expansion of the frame, while substantially maintaining the positions of the vertical strands in the active portion of the mask.

摘要： The present invention relates to cathode ray tubes (10) and specifically to a cathode ray tube having an improved electrical connector (40). The tube comprises a faceplate panel (18) and a funnel-shaped back section having a neck (14) containing an electron gun. The neck terminates at a closed end stem (36) through which electrical leads (34), of the electron gun, extend and terminate at the outer surface of the stem. An electrical connector is provided for detachably coupling an electrical lead to the electron gun. The connector has a through passage defined by a diameter greater than the diameter of the neck. The neck is inserted in the passage and the connector is secured to the outer surface of the neck. Adjacent the passage is a plurality of integral resilient leaf springs (46) extending toward the stem at a plurality of circumferentially spaced locations. The leaf spring elements include base elements (48) for terminal engagement and tip ends projecting and bias toward the electrical leads of the electron gun to provide electrical connection to the cathode ray tube. The passage of the connector is preferably defined by an opening in a printed circuit board or other electrical terminal contact from which the leaf springs extend.

摘要： The invention includes an apparatus (40) for developing a latent charge image formed on a photoreceptor (36) disposed on an interior surface of a faceplate panel (12). The apparatus (40) comprises a developer tank (42) having a sidewall (44) closed at one end by a bottom portion (46) and at the other end by a panel support (48) having an opening (50) therethrough to provide access to the faceplate panel (12). A back electrode (52) has a potential applied thereto to establish an electrostatic drift field between the back electrode and the photoreceptor (36), which is grounded. Triboelectrically-charged, dry-powdered, light emitting phosphor material, having a charge of the same polarity as the potential applied to the back electrode (52), is sprayed into the developer tank (42), between the back electrode (52) and the faceplate panel (12). The triboelectrically charged phosphor material is directed toward the photoreceptor (36) on the faceplate panel (12) by the applied electrostatic drift field. A bias shield (65) comprising two pairs of insulative shield members (66) and (68) disposed around a peripheral sidewall (18) of the faceplate panel (12). At least one conductive strip (72) is provided on one of the major surfaces of the shield members to repel the triboelectrically charged phosphor material from the panel sidewall (18) and to influence the deposition of the phosphor material on the photoreceptor, at the edge thereof. A method of developing the latent charge image utilizing the bias shield also is described.
