Abstract

1. 발명이 속하는 기술분야1. Field of invention

모니터monitor

2. 종래의 문제점에 대한 기술적 과제2. Technical problem of conventional problems

종래에는 사용자가 피-시 세트업시 해상도 선택을 피-시에 장착된 비디오 카드 해상도 범위안에서 선택함으로서 실제 모니터에 공급되는 수평주파수나 수직주파수를 사용자가 인식못하는 상황에서 피-시를 세트업 하기 때문에 오버주파수 세팅시 모니터 화면의 홀드가 무너져 마치 모니터 불량으로 인식되어 사용자에게 불쾌감을 줄 뿐만 아니라 장시간 방치시 모니터에 충격을 가하게 되므로 모니터의 수명단축은 물론 신뢰성이 저하되는 등 문제점이 있었다.In the past, the user sets up the PC in a situation where the user does not recognize the horizontal frequency or the vertical frequency supplied to the actual monitor by selecting the resolution setting during the PC setup within the video card resolution range mounted on the PC. When the over frequency is set, the hold of the monitor screen collapses, which is perceived as a bad monitor, which not only causes discomfort to the user but also impacts the monitor when left for a long time, thereby reducing the life of the monitor and reducing reliability.

3. 발명이 해결하려는 기술적 과제3. The technical problem to be solved by the invention

모니터에 오버주파수가 인가되면 인가된 오버주파수를 디-시전압으로 변환시켜 변환된 디-시전압과 기준전압보다 높으면스위칭회로에 하이신호를 인가시켜 버져를 통해 경보음을 발생시켜 주므로서 사용자가 피-시 재 세트업시켜 모니터를 안정되게 사용할 수 있게 하고, 또한 모니터의 수명을 연장시킴과 동시에 신뢰성을 향상시킬 수 있게 한 것이다.When the over frequency is applied to the monitor, the applied over frequency is converted into a de-time voltage, and if it is higher than the converted de-time voltage and the reference voltage, a high signal is applied to the switching circuit to generate an alarm sound through the buzzer. By re-installing the PC, the monitor can be used stably, and the life of the monitor can be extended and reliability can be improved.
