摘要： A video display apparatus (10) includes a cathode ray tube (12) having an ultor terminal for developing an ultor voltage at the ultor terminal to produce a beam current. The ultor voltage has voltage fluctuations in a presence of changes in the beam. A resistive voltage divider (28) is coupled to a source of a first high voltage and to a focus terminal (220) of the cathode ray tube for producing at the focus terminal (220) a second high voltage including voltage fluctuations. The voltage fluctuations are indicative of the voltage fluctuations of the ultor voltage to provide for focus voltage tracking. An amplifier (22) responsive to a periodic correction signal is capacitively coupled via a capacitor (302) having a value of 33 picofarad to the focus terminal. A dynamic focus voltage that varies, in accordance with a variation of a beam landing location, is produced at the focus terminal (220).

摘要： Disclosed is a photographic printer with bi-directional sweeping of a color CRT (116) to expose a photosensitive medium (120). Image data from a host system is received by the printer and stored in a data drive system (112). The data drive system (112) converts the data into a series of rows of dot row data to produce the appropriate image desired. Linear deflection amplifiers sweep the CRT's electron beam across the color phosphor areas on the face of the CRT (116) to expose the medium (120) utilizing the dot row data. The present invention sweeps and writes data bi-directionally, eliminating the retrace period associated with sweeping and writing in one direction, and without any hold periods once printing starts. The data in every other dot row is processed in reverse order so that the dot row data utilized in the reverse writing sweep will be exposed onto the medium (120) in proper relationship to the rows written before and after it.

摘要： The horizontal and vertical deflection factors for a split anode beam penetration color CRT are compensated for changes and remain constant as trace color is varied. In an electro-statically deflected tube a correction lens (17) near an expansion mesh (21) and electrically connected to the split anode faceplate alters the radial velocities of electrons leaving the mesh such that their point of impact upon the faceplate is unaffected by changes in axial velocity induced to change trace color. In a magnetically deflected tube a correction lens (55) in the neck near the entrance to the deflection yoke is supplied with a voltage that varies in conjunction with that of the faceplate. The axial velocity of the electrons in the region of magnetic deflection is adjusted to produce amounts of deflection that remain constant despite changes in the faceplate voltage.

摘要： There is disclosed a cathode-ray tube which employs an electron gun assembly of the laminar flow (LF) type (20, 21, 22). The beam emanating from the LF electron gun assembly is directed through a three-electrode einzel lens assembly (30, 31, 32) where the center electrode of the einzel lens assembly is subjected to a modulation voltage. Positioned after the einzel lens assembly are magnetic deflection circuits which include a horizontal (41) and vertical (42) coil enabling the beam to deflect in the horizontal and vertical directions and which circuits are positioned internally within the CRT. A convergence assembly is also built within the neck of the CRT. Thus, the CRT provides the advantages of the laminar flow gun while enabling modulation of the electron beam to provide an extremely small spot size to enable the CRT to operate with small spot size and to provide more efficient deflection at higher modulation rates.
