Patent number: 6507373Abstract: In a video stabilizing circuit for a display apparatus, the clamp levels of R, G and B chromatic signals are controlled by feeding back the output currents of respective R, G and B terminals so that real time responses can be made, as against the fluctuations of video output load, thereby obtaining high brightness displays. The circuit according to the present invention is characterized in that output currents of R, G and B terminals are fed back from video output sections to clamp level control sections. The potential of a cut-off control terminal of the video pre-amplifier is then varied in such a manner that, if the beam current sensed by the clamp level control section is large, the bias voltage of the chromatic signals is made small. If the beam current sensed by the clamp level control section is small, the bias voltage of the chromatic signals is made large. Therefore, during a high brightness display, fluctuations in the brightness of the high beams and low beams is reduced and display is improved.Type: GrantFiled: March 17, 1999Date of Patent: January 14, 2003Assignee: Samsung Electronics Co., Ltd.Inventor: Seung-Taek Lee
