The operation of the conventional adjusting device for the cathode ray tube display device having such a configuration will be described. First, the antenna 3 in the cathode ray tube display device 1 receives a broadcast signal, generates an RF signal, and sends the RF signal to the tuner 4. The tuner 4 demodulates a desired broadcast signal selected under the control of the music selection microcomputer 4a. The video processing circuit section 5 removes, amplifies, and detects interfering waves of the video intermediate frequency circuit signal demodulated by the tuner, and performs analog-to-digital conversion processing and cross-color and dot interference processing by three-dimensional Y / C separation. Is separated into a luminance signal and a carrier color signal, and the adjustment circuit section 6 (VP6a, DA
C6b).

The VP 6a of the adjusting circuit section 6 performs a luminance signal amplification and a chrominance signal amplification, and also performs an operation of converting into R, G and B signals by RY demodulation, BY demodulation and GY matrix processing. . Further, the VP 6a controls the picture and the hue by the control signal from the main microcomputer 7 according to the control format of the I ² CBUS interface, and also adjusts the horizontal and vertical positions, the linearity (S-shaped correction) and the display position such as the pin phase. Fine-tune. Fine adjustment of these deflection circuit systems is performed digitally by a video processor based on digital control data. The DAC 6b of the adjustment circuit unit 6 performs so-called dynamic convergence adjustment including the screen peripheral portion by converting the control data into an analog value and acting on the predetermined adjustment circuit, and follows the function of the VP 6a, for example, V scroll, It controls the sub V size and the lower V linearity. In the screen display IC8, the main microcomputer 7
Predetermined data necessary for screen display sent from the (display microcomputer) is received, shaped as R, G, and B signals for pipe surface display, and output to the VP 6a. The R, G, and B signals for display on the screen are superimposed on the input video signal by the VP 6a and displayed on the screen of the cathode ray tube 9.

In the cathode ray tube 9, an electron beam is emitted from an electron gun (not shown) on the basis of the input video signal, and the electron beam is controlled by a deflection yoke and a neck assembly such as landing and convergence, and the cathode ray tube. A predetermined screen is displayed by horizontally and vertically scanning a phosphor screen formed on the panel portion of No. 9. In the case of a color cathode ray tube,
The electron beam emitted from the electron gun is prepared for each of the three primary colors of red (R), green (G), and blue (B), and corresponds to the three primary colors emitted from the electron gun. The electron beam is focused and just converged using the electron beam passage hole, and the three color phosphors of the phosphor screen are selectively stimulated to display a predetermined image.

In the adjusting device 2, the operator controls the display position and the like by operating the controller 12 connected to the personal computer. The controller 1
