20110193844 | POWER SOURCE CIRCUIT AND DISPLAY APPARATUS HAVING THE SAME - A power source circuit of a display apparatus includes a voltage divider, an operational amplifier, a first switch, a second switch, and a protector. The voltage divider generates a divided voltage between a first driving voltage and a ground voltage. The operational amplifier receives the divided voltage and outputs the divided voltage as a second driving voltage. The first switch is connected between a first supply voltage terminal to receive the first driving voltage and a common node. The second switch is connected between the common node and a second supply voltage terminal to receive the ground voltage. The protector is connected to the common node to limit a voltage output of the first supply voltage terminal in response to a voltage of the common node. | 08-11-2011 |
20130342590 | THREE-DIMENSIONAL IMAGE DISPLAY APPARATUS AND METHOD OF DRIVING THE SAME - A display apparatus includes a display panel including left-eye pixels and right-eye pixels, a three-dimensional controller which separates a first image signal into left-eye and right-eye image signals, outputs a second image signal such that the left-eye image signal is applied to the left-eye pixels during a left-eye frame, a black image signal corresponding to a black data is applied to the right-eye pixels during the left-eye frame, the black image signal is applied to the left-eye pixels during a right-eye frame, and the right-eye image signal is applied to the right-eye pixels during the right-eye frame, and an image display controller which controls the second image signal in response to a control signal, where the left-eye pixels are alternately arranged with the right-eye pixels in the unit of two pixels in a first direction and in the unit of a predetermined number of pixels in the second direction. | 12-26-2013 |
20140368562 | DISPLAY DEVICE HAVING IMPROVED CONTRAST RATIO - A display device includes a display panel, a gray-scale voltage generator, and a data driver. The data driver includes a first amplifier. The first amplifier includes a first voltage input terminal configured to receive a first voltage, a second voltage input terminal configured to receive a second voltage lower than both the first voltage and a common voltage to be applied to a pixel included in the display panel, an input terminal configured to receive a gray-scale voltage having a gray-scale level corresponding to image data, and an output terminal configured to output the data voltage as a buffered voltage corresponding to the gray-scale voltage. | 12-18-2014 |
