| 20080238858 | BACKLIGHT UNIT, DISPLAY APPARATUS AND CONTROL METHOD THEREOF - A display apparatus includes: a display panel; a light source unit which comprises a light source and has a plurality of division areas which are separated and independently driven each other, and is located at the back of the display panel; a drive unit which supplies drive power for the light source unit; and a light source controller which controls the drive unit so that the drive power can be supplied sequentially to the division areas which are divided in a first direction, in synchronization with a scanning period for which one frame of an image signal is displayed, and a lighting period of the division areas can be changed according to the kind of the image signal which is displayed on the display panel. | 10-02-2008 |
| 20090141049 | DISPLAY APPARATUS FOR COMPENSATING OPTICAL PARAMETER USING FORWARD VOLTAGE OF LED AND METHOD THEREOF - A display apparatus for compensating an optical parameter, and a display method thereof are disclosed, the display apparatus including a display, an optical source unit, a voltage detection unit which measures the forward voltage of an optical source, and a control unit which controls driving of the optical source unit using a forward voltage of the at least one optical source. Accordingly, the variation of optical parameter is accurately compensated, and the cost for fabricating a temperature sensor and the time for measuring the temperature are reduced. | 06-04-2009 |
| 20090244112 | DISPLAY APPARATUS AND METHOD THEREOF - A display apparatus and method thereof are provided in order to provide a high quality image. The display apparatus includes a driving unit which drives light sources, and a controller which controls the driving unit. Therefore, it is possible to reduce motion blur and flicker and maximize the gray level difference, so that a user may be provided with a clear image. | 10-01-2009 |
| 20090256812 | DISPLAY APPARATUS AND CONTROL METHOD OF THE SAME - A display apparatus includes a display panel having a light emitting device, a sensor which senses an electric current flowing in the light emitting device, and a controller which determines that an external stimulus occurs to the display panel if a change of a sensed current exceeds a preset current change rate, and performs a predetermined operation on the basis of a determination result. | 10-15-2009 |
| 20090268977 | METHOD FOR IMPROVING IMAGE QUALITY AND DISPLAY APPARATUS - A method of improving image quality and the display apparatus thereof are provided. The method includes generating a plurality of sub-frame images using a frame image depending on whether the frame image is a moving image or a still image and displaying the plurality of sub-frame images sequentially for a frame time interval of the frame image. By generating the plurality of sub-frame image which have different pixel values each other and displaying the plurality of sub-frame image sequentially, the sticking phenomenon may be prevented and a life time of the display apparatus may be extended. | 10-29-2009 |
| 20090278775 | DISPLAY APPARATUS AND CONTROL METHOD OF THE SAME - A display apparatus includes: a display unit which displays an image; and a signal controller which generates a first sub-frame having a mean brightness by calculating the mean brightness of an original frame input from an outside, generates at least one second sub-frame for compensating the first sub-frame on the basis of the first sub-frame and the original frame, and outputs the first sub-frame and the second sub-frame to be displayed on the display unit in sequence. | 11-12-2009 |
| 20100309120 | DISPLAY APPARATUS AND METHOD - A display apparatus includes a display panel which include a plurality of areas; a communication unit which receive information about brightness sensed by a pointing device; a backlight unit which includes a plurality of light sources; and a controller which controls the backlight unit to change the brightness of the plural areas by a predetermined unit, and determines a pointing position of the pointing device on the basis of relative variation in the information about the brightness. With this, it is possible to detect a pointing position of a pointing device in a display apparatus having a hold-type display panel. | 12-09-2010 |
| 20100315494 | DISPLAY APPARATUS AND CONTROL METHOD OF THE SAME - Provided are a display apparatus and a control method of the same. The display apparatus includes: an organic light emitting panel which alternately scans a left-eye image and a right-eye image in units of a frame; a signal transmitter which outputs a control signal to external shutter glasses to open or to close a left-eye shutter and a right-eye shutter of the shutter glasses; and a controller which controls the signal transmitter to make open and closed states of the left-eye shutter and the right-eye shutter be opposite to each other, and controls emission of the organic light emitting panel to display an image corresponding to an open shutter and not to display an image opposite to the open shutter when one of the left-eye shutter and the right-eye shutter is open. | 12-16-2010 |
| 20110149054 | 3D GLASSES, METHOD FOR CONTROLLING 3D GLASSES, AND METHOD FOR CONTROLLING POWER APPLIED THERETO - Three-dimensional (3D) glasses, a method for controlling 3D glasses, and a method for controlling an on/off operation of the 3D glasses are provided. The 3D glasses rotate a glass unit based on sensed motion information to maintain a polarization direction of the glass unit in a particular direction. Therefore, a user may view 3D images in various positions. In addition, a user manages the on/off operation of the 3D glasses using the sensed motion information, thereby conveniently viewing 3D images in various positions. | 06-23-2011 |
