リテイ自動調整方式に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides an in-line color cathode ray tube for color television in which an electron beam emitted from an electron gun illuminates the three-color phosphors of red, green, and blue coated on the front surface of the cathode ray tube. This invention relates to an automatic pilot adjustment method that adjusts the landing of an electron beam so that it emits light accurately.

部ピユリテイ調整と呼んでいる。 Conventional pressure adjustment is performed in the following steps. First, a single-color, full-screen raster signal is applied to an in-line color cathode ray tube (hereinafter abbreviated as CPT) so that the entire screen will display only one color of red, green, or blue. And as shown in Figure 1,
By moving the deflection yoke 2 located at the neck part of the CPT 1 back and forth in the axial direction and intentionally shifting the deflection center of the deflection yoke 2 from the exposure center of the CPT 1,
As shown in FIG. 2, a color belt 5 of the same color as the input signal is created on the screen 7. Next, there is a magnet 3 for adjusting the tightness configured in the neck part of CPT1.
The center of the color belt is made to coincide with the center 6 of the screen. That is, the electron beam is made to accurately hit the phosphor at the center of the screen. This is called central pipulity adjustment.

ユリテイ調整と呼んでいる。 Next, the deflection yoke 2 is moved back and forth from the above position to adjust the entire surface of the cathode ray tube to have the same monochromatic color as the central part, so that the electron beam accurately hits the phosphor even in the peripheral part of the screen. This is called peripheral area adjustment.

イングを起こしやすいという欠点があつた。 However, in the former case of adjusting the central portion, the color belt at the center does not actually become a belt-like 4 with a uniform width, but becomes a belt-like 5 with an uneven width, and the boundary line of the color belt is not clear. It was difficult to accurately match the center of the CPT screen and the center of the color belt through visual adjustment by an adjuster. As a result, variations in adjustment and a decrease in adjustment accuracy are unavoidable, and the beam landing, which was good at the time of adjustment, has no margin, so mislanding is likely to occur depending on the installation direction of the receiver, temperature, and aging. It was hot.

ある。 In addition, as a means of detecting the position of the color belt on the screen, the monochromatic color belt generated on the color cathode ray tube screen is photographed with a black and white television camera through a filter of the same color, and the video signal waveform obtained from this is captured in binary form. One possible method is to use the converted signal to detect the belt width on the screen. However, according to such a method, stable and accurate detection is difficult due to the influence of sensitivity variations (shading characteristics) in the scanning position of the camera.

To provide an automatic adjustment system for a central part pipulity to eliminate variations in adjustment.

のカラーベルトを発生させるのである。 The method of the present invention uses a black-and-white television camera installed on the central axis extension of the CPT screen under test to project the entire CPT screen into view through an optical filter of the same color as the color belt projected onto the CPT screen. Take a photo. Next, we extract the video signal from the black and white television camera that corresponds to the vertical and horizontal center positions of the CRT screen, and adjust the signal brightness level to the CRT to bring it to a predetermined value, thereby adjusting the screen brightness. Set to a given value. Furthermore, two left and right points 1A and 1B, which are at the vertical center of the screen and are almost symmetrical with respect to the horizontal center line, are designated as monitoring points.
Extract the amplitudes V 1A and V 1B of the video signal from the black and white television camera which correspond to the brightness of the colors of the color belt of the screen at points 1A and 1B . and the deflection yoke
From the rear (electron gun side) to the front (CPT
(screen side) while detecting V 1A + V 1B ,
At a point where the detected value moves further forward from the maximum position, the deflection yoke is positioned at a position where the detected value decreases by a certain amount from the maximum value, and the width of the color belt on the CPT screen is set to a predetermined amount. The reason for this is that the collar belt width is maximum at the position where the added value is maximum, and if the deflection yoke 2 is moved forward or backward from this position, the belt width becomes narrower. Here, in a state where the belt width is slightly narrower than the maximum width, the detection accuracy of the belt position is improved. Furthermore, setting the deflection yoke 2 forward will improve the adjustment accuracy after the final peripheral pipulity adjustment, so the deflection yoke 2 is moved forward by a predetermined value from the maximum value to generate a constant color belt. It is.

ある。 Next, set multiple sets of monitoring points similar to the one set of left and right monitoring points on the screen, for example, at the top, center, etc. of the screen.
A magnetic twilling ring is installed at three locations at the bottom to determine the left and right difference (V iA − V iB ) between the video signal extraction values at each of the locations, and the magnetic twilling ring is installed at each monitoring point so that the difference value at each monitoring point becomes zero. The color belt is rotated to accurately set the position of the color belt at the center position in the horizontal direction of the CPT screen, and automatically adjusts the center pipulity.
