Abstract: PURPOSE:To control stably a scan by performing the scanning control of an electron beam based on an index signal obtained by scanning the electron beam in the main scanning direction while the beam is oscillated minutely in the subscanning direction. CONSTITUTION:The index lines extended in the main scanning direction of the electron beam at the inside face of a screen 21 of a cathode ray tube 20 are arranged and formed in the subscanning direction at a prescribed interval and each fluorescent body line is arranged and formed sequentially one by one line between the index lines. The electron beam is scanned in the main scanning direction while being oscillated minutely in the subscanning direction and luminance modulation is applied to a beam spot from a luminance modulation circuit 14 in synchronizing with this minute oscillation. Further, the index signal obtained from the index line is applied to a synchronizing detecting circuit 17 through a band pass filter 16 so as to obtain a prescribed level of the synchronizing detection output.

Abstract: PURPOSE:To detect easily position information regarding a fluorescent body line, by providing two kinds of index lines so that the upper and lower adjacent positions in the vertical direction are reversed each other by an odd field line and an even field line. CONSTITUTION:Plural color phosphor lines CL are extensively provided in the horizontal direction, on the inside face of a screen of a CRT, and between them, a guard band of no-color is formed. Two kinds of index lines IL1, IL2 which can be detected by being discriminated from each other, with regard to the respective adjacent lines on both sides of an optional line CL are applied and formed on these guard bands, respectively. When said lines IL1, IL2 are provided so that the upper and lower adjacent positions in the vertical direction are reversed each other by an odd field line CLO and an even field line CLE, landing control of an electronic beam to the line CL can be executed very easily by such control as a detecting level difference of the lines IL1, IL2 becomes ''0''.

Abstract: PURPOSE:To prevent double scanning of an electron beam to each fluorescent line, by arranging color fluorescent lines in parallel with the direction of screen main scanning of a cathode ray tube toward the subscanning direction with a prescribed line density. CONSTITUTION:Plural number of color fluorescent lines 3 are arranged successively on a display plane of the cathode ray tube toward the subscanning direction orthogonal to the main scanning direction. A color discriminating marker 6 corresponding to respective illuminated colors is provided at the main scanning start position of the electron beam of the color fluorescent lines 3. The scanning is done by the electron beam and the color of each color video signal is switched based on a color discriminating signal obtained by detecting the color discriminating marker 6. The color discriminating signal precedent one horizontal period is stored at the same time and when the color discriminating signal obtained at the start of scanning is coincident with the color discriminating signal precedent one horizontal period, blanking is applied to a video signal of said scanning period.

Abstract: PURPOSE:To ensure the accurate beam landing of each line and to simplify the circuit constitution despite the inferior vertical deflection linearity, by compensating the beam position from an error of beam position set before a 1H delay when the horizontal scan is started. CONSTITUTION:Plural belt-shaped color fluorescent material lines 3 are extended toward an arrow X, i.e., the main scanning direction of an electron beam on the inner surface of a screen 2 which functions as a display screen of a CRT. At the same time, odd and even numbers of field lines are arrayed alternately with a fixed pitch P toward an arrow Y in the secondary scanning direction orthogonal to the lines 3. Then a guard band 4 having no emission of light is formed between lines 3, and furthermore an index line 5 is formed with every 2nd band 4. A beam position compensation control circuit detects the volume of the electron beam to the line 5 and compensates the electron beam position in the secondary scanning direction. The lines 3 which are contiguous to each other at one side of the line 5 are defined as odd field drives while defining the adjacent lines 3 at the other side of the line 5 as even field drives respectively.

Abstract: PURPOSE:To obtain a circuit which can accurately match the convergence of each part even with difference of the convergence correcting value due to unequal winding of a deflection coil, by splitting a screen into a plurality and performing the convergence at each split part independently. CONSTITUTION:To an input terminal 1, a signal superimposing a parabola wave of vertical period on a horizontal period parabola wave is applied and to an input terminal 2(3), a signal superimposing a vertical period parabola wave on a horizontal period lower right (upper right) saw tooth wave is applied. Vertical and horizontal synchronizing signals are applied to input terminals 4 and 5 respectively and a signal inverted at the center of the vertical and horizontal scanning periods is formed with monostable multivibrators 30 and 31. Thus, a switch 24 turns on at the upper left quadrant of the screen, a signal from the terminals 1 and 2 is adjusted with variable resistors 11 and 19 for convergence. Similarly, switches 25, 26 and 27 are sequentially closed and the convergence is made in the order of upper right, lower left and lower right.

Abstract: PURPOSE:To obtain a circuit which detects a shift in vertical center and compensates fluctuations of a screen, by utilizing an index signal, obtained by scanning a part other than an effective screen horizontally, as information on the position of the vertical center. CONSTITUTION:Stripes of fluorescent materials for obtaining an index signal SI are arranged above or below an effective screen area, and detected by a photodetector 2. The detection output of the index signal obtained by scanning a prescribed position outside of the effective screen with a beam is utilized as information on the position of a vertical center. When the vertical center is at the correct position, the index signal is detected only at the front half of the screen, and a gate circuit 31 gates a multiplier output PI by the 2nd selection pulse PC as the reference signal of the vertical center; and the gate output GC is made into a DC output, which is supplied to a control transistor (TR) Q2. If the vertical center shifts, the control voltage applied to the TRQ2 varies and the compensation voltage applied to a vertical deflecting coil VDY also varies, thereby compensates the vertical center.

Abstract: PURPOSE:To obtain a beam index type color TV picture receiver which is free from the color shift and the hard-to-see screen where the black comes out, by installing the index stripe in addition to the index fluorescent substance stripe. CONSTITUTION:Index stripe IY is provided in addition to index fluorescent substance stripe IX for production of the gate pulse which gates each primary color signal, and the position of stripe IY is detected by optical detector 21Y to obtain mode set pulse PS at the fixed position to the position of IY. And the control is given to the phase of the gate pulse to gate each of primary color signals ER, EG and EB via pulse PS. In such way, such inconvenience can be eliminated as the color shift or the like of the reproduced picture caused by the trouble in which the video signal turns balck in the course of the horizontal scanning period and thus no beam current flows. At the same time, the hard-to-see screen where the black comes out can be avoided.
