In a grid constructed from bright, horizontal and vertical stripes (SH, SV), the vertical stripes (SV) are less bright than the horizontal stripes (SH). The aim of the invention is to eliminate this difference in brightness without appreciably altering the circuit. To this end, the amplitude (AH) of the pulse sequence (V) for the vertical stripes (SV) is increased in relation to the amplitude (AH) of the pulse sequence (H) for the horizontal stripes (SH). Application, in particular, to projection TV sets with large projection surfaces. |
