A touch sensitive active matrix display device is provided. The invention incorporates polysilicon gates bridging SCR diode junction elements and also bridging between SCR elements and neighboring STI structures. Aerosol particles are deposited on the surface during collection and are subsequently eluted with a microdroplet or a series of microdroplets as a concentrated liquid sample so that the sample can be analyzed in situ or conveyed to a detector for analysis. Even when the block process condition is false, it is determined whether to form a dot in the target block. The flexible member includes an outer portion and an inner extension protruding from the outer portion which vibrates to attenuate low frequency sound energy transmitted from the air conduit. The device comprises: a fluid inlet; a fluid outlet; a flow-through fluid treatment zone having comprising: a radiation source, an adsorbent and a photocatalyst.
