Abstract

터치 태블릿 혹은 그래픽 태블릿과 같은 전자 장치는 특정 시간 간격 동안 전자기 노이즈를 발생하는 디바아스를 갖춘, LCD와 같은, 디스플레이 수단을 구비한다. LCD의 반복적인 행반전 동작은 전자기 노이즈를 발생한다. 장치는 디스플레이 수단과 공동 작업하기 위해 데이타 처리 전자 회로를 포함한다.Electronic devices, such as touch tablets or graphic tablets, have display means, such as LCDs, with a devias that generate electromagnetic noise during certain time intervals. Repeated inversion operation of the LCD generates electromagnetic noise. The apparatus comprises data processing electronic circuitry for working with the display means.

장치는 전자기 노이즈에 대해 회로의 자화율을 감소시키기 위해 회로에 결합된 보호 수단을 또한 포함한다. 보호 수단은 특정시간 간격에서 회로를 최소한 부분적으로 디스에이블링하는 디스에이블링 수단을 구비한다.The apparatus also includes protection means coupled to the circuit to reduce the susceptibility of the circuit to electromagnetic noise. The protection means comprises disabling means for at least partially disabling the circuit at specific time intervals.
