Abstract: A display panel driving apparatus includes a data processing circuit, a data driver, and a gate driver. The data processing circuit increases a first gamma value of input image data of which the gamma value is 0, according to a second gamma value of the input image data of which the second gamma value is not 0. The data driving part outputs a data signal based on the output image data to a data line. The gate driving part outputs a gate signal to a gate line.

Abstract: A computer includes a main body having a housing part, a main display unit connected to the main body which displays images, and an auxiliary display apparatus having an auxiliary display unit which displays additional images, wherein the auxiliary display apparatus is insertable into the housing part.

Abstract: The present general inventive concept relates to a computer having a network part to transmit and receive data through a network; a data storage to store downloaded data received through the network part, a mode selector to select one of a first download mode and a second download mode, a first download manager to control the data storage to store the downloaded data received through the network part when the first download mode is selected by the mode selector, and a second download manager to control the data storage to store the downloaded data received through the network part when the second download mode is selected by the mode selector. Thus, a computer capable of switching to a power save mode while the computer downloads data through a network is provided, so that a power consumption is reduced.
