Abstract: 732,234. Colour television tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd April 29, 1952 [May 2, 1951], No. 10758/52. Class 39 (1). A colour television camera has a grid between the accelerating anode and the target plate of the tube which is positive with respect to the cathode and controls by potential variation the direction of the scanning beam between the grid and the target the .beam direction being at an angle to the lines of force between grid and target, and colour filters extending parallel to the grid wires producing colour sequences on the target plate. The grid also exercises a focusing action on the beam. In Fig. 6, an image formed by lenses 34 and a strip colour filter 35 is thrown onto the photo-senstive layer 31 of the target 30 as a series of colour charge images, each aperture of the grid corresponding to three strips of the filter coloured red, green and blue. Scanning by the beam 36 yields a signal across resistor 33, its direction being either parallel or at right angles to the lines of the grid. In the former case, the scanning may be dot-sequential following a zig-zag or sine wave course over the three colour lines. With scanning at right angles to the grid direction, each colour line is a series of dots in a field- or line-sequential system. In the image iconoscope of Fig. 9 (not shown) rotation of the electron image due to the magnetic focusing coil is compensated by arranging the filter elements at an angle to the line of the grid wires, and a grid anode is provided between the deflection grid and the storage target. The angular disposition, curvature and spacing of the grid and the target may be the same as described in Specification 732,235. The camera may be used in stereoscopy.
