Abstract

본 발명은 프로젝션 티브이(Projection TV)의 멀티-모드(Multi-Mode) 뿐만 아니라 멀티-싱크(Multi-Sync)에서도 대응 가능한 콘버젼스 조정장치 및 방법에 관한 것이다. 본 발명은 각 디스플레이 모드별로 같은 어드레스를 발생시켜 콘버젼스 조정 데이타를 에스램으로 부터 불러내어 이를 처리한다. 이때, 디스플레이 모드절환시 디스플레이 모드별로 증폭부의 이득이 다르므로 각 모드의 주사선별로 이득을 조정하여 콘버젼스를 출력하여 보내면된다. 본 발명의 콘버젼스 조정장치 및 방법은 귀선신호의 주파수가 크게 차이가 없을때, 주파수대별로 대표되는 이득값을 확보하면, 멀티-싱크에서도 가능하고 모드전환시 주사선별 이득값만 연산하면 되므로 빠른 시간에 대응가능할 뿐만 아니라 메모리의 용량을 낮출 수 있다.The present invention relates to a convergence adjustment device and method that can be used not only in the Multi-Mode of the Projection TV but also in the Multi-Sync. The present invention generates the same address for each display mode and retrieves the convergence adjustment data from SRAM and processes it. In this case, since the gains of the amplifiers are different for each display mode during display mode switching, the gain may be adjusted and output for each scan line in each mode. In the convergence adjusting device and method of the present invention, when the frequency of the retrace signal is not significantly different, if the gain value represented by the frequency bands is secured, it is possible to multi-sync and only the gain value for each scan line needs to be calculated during mode switching. Not only can it cope with time, but it can lower the memory capacity.
