But Zworykin later abandoned research on the Image Dissector, which at the time required extremely bright illumination of its subjects to be effective, and turned his attention to what would become the Iconoscope.

On April 24, 1936, RCA demonstrated to the press a working iconoscope camera tube and kinescope receiver display tube ( an early cathode ray tube ), two key components of all-electronic television.
33.
In 1933 refines iconoscope made by Kataev . Patents the transfer of " electronic image " with conductive photocathode on dielectric ( copyright certificate dated September 30, 1933 with priority from February 20, 1932 ).
34.
The image iconoscope is essentially identical to the super-Emitron, but the target is constructed of a thin layer of isolating material placed on top of a conductive base, the mosaic of metallic granules is missing.

I put in a search for " Tihanyi + Kalman " and although you do not have an article yet about this, the true inventor of the iconoscope, you do refer the user to Memory of the World.

According to Albert Abramson, Zworykin's experiments started in April 1931, and after the achievement of the first promising experimental transmitters, on October 23, 1931, it was decided that the new camera tube would be named the iconoscope.
37.
As part of this they had developed a miniaturized iconoscope, the 1846, suitable for use in aircraft . In 1941 these were experimentally used to fly drone aircraft and in April 1942 one of these was flown into a ship about away.
38.
While the iconoscope and the intermediate orthicon used capacitance between a multitude of small but discrete light sensitive collectors and an isolated signal plate for reading video information, the image orthicon employed direct charge readings from a continuous " electronically charged " collector.
39.
The bottom line is : what Zworykin invented in 1923 and 1925 was NOT the iconoscope, merely a rudimentary electronic television very much like the television system described by A . A . Campbell Swinton in his historical article published on December 7, 1911 in Nature!

September 24, 1931, six weeks earlier than our compatriots who emigrated to the United States, Vladimir K . Zworykin with his iconoscope made by Kataev, is applying for invention and 30 April 1933 receives the Copyright certificate of the USSR No . 29.865.
