Abstract
864,233. Television. SYLVANIA-THORN COLOUR TELEVISION LABORATORIES Ltd. Jan. 15, 1960 [Jan. 19, 1959], No. 1966/59. Class 40(3) The invention relates to a television picture display device comprising a rectangular array of elementary electroluminescent areas 11 to which picture signals are routed in turn by means of switching potentials applied in appropriate sequence to a set of vertical conductors 13(1), 13(2), 13(3) &c. and a set of horizontal conductors 15(1), 15(2), 15(3). In accordance with the invention, the horizontal conductors are arranged in the manner shown so that in operation based on conventional interlacing of horizontal lines the signal is applied to two different alternating sequences of elementary areas, one sequence consisting of the oddnumbered areas of the first line of areas, the even-numbered areas of the second line, the odd-numbered areas of the third line, the even-numbered areas of the fourth line, and so on, and the other sequence consisting of the evennumbered areas of the first line, the oddnumbered areas of the second line, the evennumbered areas of the third line, the oddnumbered areas of the fourth line, and so on. The arrangement corresponds to the dot interlacing described in Specification 850,024 wherein each interlaced raster is constituted by a plurality of small areas arranged at points defining a diamond matrix, the points of one matrix occurring at the centres of the diamonds of the other matrix. An alternative arrangement may be based on Fig. 2 of Specification 850,024 so that the horizontal conductors need not cross each other. The invention may be employed in colour television. Proc. I.R.E. 1958, pages 1,654 and 1,808 is referred to for details of the electroluminescent display and associated switching devices.
