摘要: A ghost key detecting circuit includes at least first and second scan lines, return a plurality of switch elements, level circuit. The is used for performing detection upon measured voltage values the lines. When value line greater than or equal to reference value, generates logic signal indicating that element corresponding current turned off. smaller on.
