Abstract: An air conditioner includes a cabinet including an inlet port and a frame including an outlet port and coupled to the cabinet. A heat exchanger is disposed between the cabinet and the frame to exchange heat with air introduced into the inlet port and discharged to the outlet port. A blocking member is configured to connect the frame and the heat exchanger to prevent air heat-exchanged with the heat exchanger from leaking into the cabinet. This structure inhibits dew from being generated on the cabinet.

Abstract: An image display device comprises a pixel circuit including a display element; a first transistor for controlling a current output to a third electrode according to a voltage applied between the first and second electrodes; a first switch for diode-connecting the first transistor in response to a select signal; a first capacitor; a second switch for coupling a first electrode of the first capacitor to a power in response to the select signal; a second capacitor; a third switch for transmitting the data voltage to a second electrode of the second capacitor in response to the select signal; and a fourth switch for intercepting the first electrode of the first capacitor and the second electrode of the second capacitor in response to the select signal.

Abstract: A display panel of an image display device including data lines for transmitting data voltages representing image signals, scan lines for transmitting select signals, and pixel circuits coupled to the data and scan lines. The pixel circuit includes a driver for outputting a current corresponding to a data voltage applied from the data line, and a display element for displaying an image corresponding to an amount of the current outputted by the driver. A first switch transmits the data voltage to the driver in response to a select signal, and a second switch transmits a precharge voltage to the driver in response to a first control signal. The value of the precharge voltage during a period in which the first control signal is applied to the second switch is different from the value of the precharge voltage during other periods.
