Abstract: A spray nozzle for providing a high efficient atomization and a uniform fluid flow pattern, includes an internal fluid channel, sealing and a spray nozzle, on which two of spray orifices are designed close to each other. The fluid flow is guided in the internal fluid channel smoothly and separated to two fluid flows inside of spray nozzle. These two fluid flows are pressed out from the spray orifices and interfered with each other right after flow out from the spray orifices. The fluid is being atomized efficiently because the spray nozzle is designed to fully utilize both flow velocity energy and flow pressure potential energy, which is well known as “Potential Core” or “Potential Zone” and will disappear in a very short distance right after fluids flow out from the spray orifices. During the fluid flows collide with each other by using the flow velocity right after flow out from the orifices, the fluid flows explode within the potential core by using the flow pressure potential energy.

Abstract: A switching transistor is controlled to turn on or off depending on a turn-on voltage or a turn-off voltage applied to a gate signal line. A driver transistor is supplied with an image signal applied to a source signal line through a switching transistor. A voltage based on the supplied image signal is retained by a capacitor. The driver transistor supplies a light-emitting current to an EL element based on the voltage retained in the capacitor. A capacitor is formed between one terminal of the capacitor (that is, a gate terminal of the driver transistor) and a gate signal line. The capacitor causes the gate terminal voltage of the driver transistor to be varied depending on variation of the potential on the gate signal line.

Abstract: A precharge voltage Vp is applied in period A. The precharge voltage Vp is generated by applying a constant current Iw to a pixel driving transistor of a display panel and using gate terminal voltage of the driving transistor which passes the constant current Iw. The gate terminal potential is held in memory. When displaying images on a display panel, the gate terminal potential is read out of memory, and used as the precharge voltage Vp after arithmetic processing. By the application of the precharge voltage Vp, a source signal line is charged and discharged quickly so that an almost target tone current will flow through the driving transistor. Furthermore, a more accurate program current is written into the pixel during period B.
