This signal is transmitted from an antenna 41 via a power amplifier 407a, a bandpass filter 408a and a switch 401. Part of this signal sneaks into an antenna 40, which receives it and the received signal is branched by a directional coupler 402a, detected by a sneak signal detector 403a, and the detected signal is outputted to a control section 404a. Then the attenuation of a variable attenuator 405a is controlled in proportion to a beat component rectified voltage to suppress a loop gain, thereby avoiding positive feedback oscillation of a sneaked signal.

Abstract: PROBLEM TO BE SOLVED: To provide an active matrix display device and its driving method capable of preventing the occurrence of horizontal cross talk due to cross capac ity between a video line and a signal line. SOLUTION: In a liquid crystal display panel 1 having three lines of video lines Video 1, Video 2, Video 3, when a drive signal becomes an H level synchronized with an end of a sampling pulse ϕH from an H scanner driving a horizontal switching element HSW by a row, an analog switch shifts a signal supplied to a video line from a video signal Vsig to a black level signal (Vsigc+V1). An AC component ΔV1 is supplied to another signal line Y by the cross capacity between the video line and the signal line, and the potential of another signal line Y is raised to Vsigc+2(V)+ΔV1.  When thin film transistors Tr by one row connected to a gate line X are turned off by a selection pulse ϕV outputted from a V scanner at its potential, a potential difference between liquid crystal pixels LC in areas A and B is eliminated, and the occurrence of the horizontal cross talk is prevented.
