Abstract

PURPOSE:To save the space of the panel surface of a receiver by dividing a screen on which a turning indication bar is projected according to a tuning voltage applied to an electronic tuning element into three areas, by performing bar display by allotting reception bands to those areas, and then by displaying a tuning channel number at the position where a bar appears. CONSTITUTION:When a tuning indication bar moving according to tuning electric power applied to an electronic tuning element is projected on the screen of CRT, the upper half of the screen is assigned to the VHF band, and the lower half to the UHF band. Further, the screen is divided into two horizontally so that while the low band of the VHF band is displayed on the left hand side, the high band may be displayed on the right hand side. Furthermore, a channel number is displayed at the position where the bar appear. The circuit that separates this bar display into the upper and lower parts is composed of AND and NOR gates 8 and 9 receiving a vertical saw- tooth wave and voltage BV supplied to a VHF tuner during VHF reception, and NOR gate 10 receiving outputs of gates 8 and 9, and displaying the VHF band at the left and right hand sides is performed by selectively applying common potential BU, BVL and BVH to terminals 11-13.
