Abstract: A pixel structure, which may be used in a liquid crystal display panel, includes a plurality of display pixel units and a plurality of control devices. Each of the display pixel units includes a first sub-pixel adapted to provide a first color, a second sub-pixel adapted to provide a second color, a third sub-pixel adapted to provide a third color, a first white sub-pixel, a second white sub-pixel, and a third white sub-pixel. Each of the control devices is employed for respectively controlling each of the sub-pixels. The liquid crystal display panel is normally white when the first sub-pixel, the second sub-pixel, the third sub-pixel, the first white sub-pixel, the second white sub-pixel, and the third white sub-pixel are not driven by the control devices.

Abstract: A display panel, a pixel circuit and a driving method of a differential voltage driving device are disclosed. The driving method includes: respectively supplying an alternating common voltage in a first polarity and a first display data in a second polarity to two terminals of the differential voltage driven device in a first frame; disconnecting the differential voltage driven device from the alternating common voltage, thereby keeping one terminal of the differential voltage driving device at the first polarity of the alternating common voltage; converting the alternating common voltage to the second polarity in a second frame which is consecutive to the first frame; and respectively supplying the alternating common voltage in the second polarity and a second display data in the first polarity to the two terminals of the differential voltage driving device in the second frame, here the first polarity is inverse to the second polarity.

Abstract: A gas water heater device includes a combustion chamber for providing a gas flow, a pipe assembly, and a heat exchanger disposed over the combustion chamber including a plurality of thermal conductors disposed in parallel with each other, each of the plurality of thermal conductors further comprising a base, a plurality of through holes accommodating the pipe assembly therethrough, and a flange for collecting condensed water formed on the base.

Abstract: A gas water heater is disclosed. The gas water heater comprises a combustion chamber, a pipe assembly, a heat exchange device, and a plurality of heat conductors. The combustion chamber provides a gas flow. The heat exchange device is disposed above the combustion chamber. The heat conductors are disposed in parallel in the heat exchange device. Each heat conductor comprises a body, a plurality of trough holes, and a first flange. The body has an oblique side facing the gas flow. The through holes are disposed on the body. The first flange is formed along the oblique side of the body for collecting condensed water.
