Abstract: 1,068,591. Television. SCOPE Inc. April 23, 1964 [June 18, 1963], No. 16909/64. Heading H4F. Field sequential colour television display apparatus adaptable for viewing black and white pictures comprises a cathode-ray tube with a display screen, scanning means to scan the screen successively and cyclicly, a colour filter mask, Fig. 2 (not shown), placed'in front of the display screen, and comprising, in order of distance from the display screen, a first rigid member 7, having a plurality of transparent stripe triplets, each comprising two coloured stripes (14) and (16) and a colourless stripe (41), arranged in consistent succession, a second flexible member 8 having alternate opaque and transparent stripes (13) and (12) respectively, and a third rigid transparent member 19, Fig. 4, fixed relative to the first member, and driving means to cause cyclic movement of the second member 8 in the space between the first and third members in synchronism with the field scanning, mechanical restrictive means limiting the cyclic movement to that required to bring the transparent stripes of the second member successively and alternately into register with the coloured stripes of the first member. The colour stripes (14) and (16) transmit light at wavelengths 605 and 500 millimicrons, but, due to the rapid changes from one colour to another, appear to transmit light at wavelengths shifted from those given towards the blue, to give a range of combination colours which occur very frequently in nature. The driving means, Fig. 4, comprises a solenoid 18, energized with A.C. via contacts 20. The second member 8 is attached to an armature 23 which vibrates within the solenoid. The mechanical restrictive means comprises a felt pad 28, and a felt pad 27 stopping the movement of shoulder 29. The vibration resistance of the armature is controlled by a spring 25 adjustable in compression by means of nut 26. The length of vibration of the armature is controlled by varying the position of the solenoid, along base 31, such that the distance between pads 28 and 27 is varied. The centre of vibration of member 8 is adjusted by movement of base 31 on chassis 34 by means of knob 32. contacts 20 are fixed on chassis 34 and are closed when base 31 is moved to the left and opened when it is moved to the right. In the right-hand position of base 31, solenoid 18 is unenergized and member 8 is stationary such that its transparent stripes are aligned with the colourless stripes in member 7. This allows a black and white picture to be viewed. In the left-hand position of base 31, solenoid 18 is energized and causes the transparent stripes in member 8 to be alternately aligned with the coloured stripes in member 7. This allows a two-colour picture to be viewed. The movement of base 31 is restricted by stop 38 and screws 36 and 37.
