Abstract:
Provided is an apparatus and method of displaying power line communication channel information. The apparatus for displaying power line communication (PLC) channel information includes a channel information determining unit which performs PLC channel estimation and determines channel information including a bandwidth which is available for a user in a power line communication network; and a channel information displaying unit which displays the channel information to the user. Since channel information is determined through channel estimation and displayed to a user, it is possible to easily check whether a channel can be used before installing a power line communication (PLC) device. In an application, information on kinds of a service which can be selected by the user or expected quality of the service can be previously checked. Accordingly, the user can know whether the communication can be performed, without installing a communication device or executing a communication application which requires much time and effort. Accordingly, it is possible to reduce time and effort necessary for finding an adequate communication point.

An organic light emitting diode display for removing a voltage which is charged into a gate electrode of a driving transistor before a current frame is changed to a next frame is disclosed. In the organic light emitting diode display, a display panel has a plurality of pixels that include an organic light emitting diode. A timing controller controls a driving timing of the inputted video data and controls a supply timing of a refresh voltage. A data driver converts a digital data which is outputted from the timing controller for a current frame into an analog data voltage to supply it to the pixels, and then supplies the refresh voltage to pixels which are selected among the pixels in accordance with a control of the timing controller. And a gate driver primarily supplies a scanning pulse for a first horizontal period of a current frame to select the pixels to be supplied with a data, and then secondarily supplies a scanning pulse for a second horizontal period of a current frame to select pixels to be supplied with the refresh voltage among the pixels in accordance with a control of the timing controller.
