The invention relates to a magnetorheological-material-based 3D (Three-Dimensional) printing type rapid prototyping method and device. According to the principle of magnetorheological effect, a magnetorheological material is used as a 3D printing raw material; and a 3D solid model is constructed by spraying the magnetorheological material on a workbench with a magnetic field, rapidly solidifying and prototyping the sprayed magnetorheological material, and then depositing the treated material layer by layer. A computer is provided with three control circuits; one circuit is used for controlling the flow of a driving pump, namely the flow at a spray head; another circuit is used for controlling the 3D motion of the spray head through a servo mechanism; and the rest circuit is used for controlling colour mixing and allocating of a colourized ink box. The magnetorheological material is solidified and prototyped by utilizing the magnetic field generated by an electromagnet. According to the magnetorheological effect of the magnetorheological material, a temperature control module in the traditional melting, spraying and rapid prototyping type 3D printing method is replaced by the magnetic field; in addition, the device disclosed by the invention is also different from a high-pressure electric field required by an electrorheological fluid effect, has the advantages of being simple in structure, low in energy consumption and cost, capable of realizing the microminiaturization and the like, and can be applicable to the fields of process design, art and entertainment, prosthesis model and the like.

A sound detecting mechanism capable of forming a diaphragm and a back electrode on a substrate by a simple process includes acoustic holes corresponding to perforations formed on a front surface of a substrate. A second protective film, a sacrificial layer and a metal film are laminated on the front surface in a portion corresponding to the acoustic holes. The substrate is etched from the back surface thereof to a depth reaching the acoustic holes to form an acoustic opening. Subsequently, by effecting an etching from the back surface of the substrate through the acoustic holes, the sacrificial layer is removed and a void area is formed between the diaphragm made of the metal film, the substrate and the formed perforations. The sacrificial layer that remains after the etching is used as a spacer for maintaining a gap between the back electrode and the diaphragm.

An embodiment of the present invention realizes a display device equipped with a self light-emitting type display element driven by a current, by using a pixel circuit having a configuration simpler than a conventional configuration. A pixel circuit includes a driving transistor (T1), an input transistor (T2), a capacitor (Cst), and three organic EL elements (OLED(R), OLED(G), and OLED(B)). Cathode terminals of the organic EL elements (OLED(R), OLED(G), and OLED(B)) are respectively connected to low-level power supply lines (ELVSS(R), ELVSS(G), and ELVSS(B)). In such a configuration, in each sub-frame, only a low-level power supply voltage (ELVSS) corresponding to the sub-frame is set to a relatively low level, and the other low-level power supply voltages (ELVSS) are set to relatively high levels.
