An OSD circuit for displaying advertising picture data on the screen of a television receiver is disclosed, and the circuit includes: an oscillator, a first counter, a second counter, a third counter, an F/F circuit, a ROM, and automatic color adjusting circuitry. The oscillator supplies clock signals to the first counter, and the first and second counters supplies horizontal and vertical scanning addresses to the ROM so as for the advertising picture data to be outputted from the ROM. The third counter, supplies a delay signal for displaying of an advertising picture data of a picture scene at a time, thereby inhibiting the output of the ROM for a certain period of time. The F/F circuit prevents a dual display of the advertising picture on the screen, and the ROM stores the advertising picture data separately for main color data, first sub-color data, second sub-color data and brightness data. The automatic color adjusting circuitry receives the advertising data consisting of the main color data, the first sub-color data and the second sub-color data from the ROM, and supplies an advertising picture having a color definitely contrasting to the color of the picture of the currently broadcasting program. If the OSD circuit of the present invention is applied to television receivers, not only advertising picture data can be continuously displayed for a certain period of time in a successive manner, but also a clear and harmonized picture color can be obtained.
