20090273558 | BACKLIGHT DRIVING CIRCUIT AND DRIVING METHOD FOR DRIVING THE SAME - A backlight driving circuit and a method for driving the same, which are capable of preventing a flicker phenomenon and delay of response, are disclosed. The backlight driving circuit includes a selective filtering unit for comparing dimming signals currently supplied for a current frame with dimming signals previously stored for a previous frame, to determine how abruptly an image of the current frame has varied from an image of the previous frame, and outputting the dimming signals for the current frame after modulating duty ratios of the dimming signals for the current frame selectively. | 11-05-2009 |
20100060555 | LIQUID CRYSTAL DISPLAY DEVICE AND DRIVING METHOD THEREOF - An LCD device adapted to apply an optimized luminance in correspondence with a brightness of each divisional region of image is disclosed. The LCD device uses dimming curves, which are provided differently from each other, for divisional regions which are divided from one frame and have different pixel numbers. Therefore, the LCD device can a luminance optimized to a brightness of each divisional region of image, thereby preventing a luminance mismatching phenomenon and a luminance nullity phenomenon. | 03-11-2010 |
20120147063 | LIQUID CRYSTAL DISPLAY DEVICE AND METHOD FOR DRIVING THE SAME - Disclosed is a display device which facilitates to display an image with the same color as an external border (external case) of a liquid crystal display (LCD) device, or to display an image satisfying a user's taste during a no-signal period, and a method for driving the display device, wherein the display device comprises a video controller which outputs interior data in accordance with a preset mode during a no-signal period; a timing controller which arranges the interior data, supplied from the video controller, in a frame unit, and outputs the arranged interior data; a data driver which converts the interior data of the frame unit, supplied from the timing controller, into analog video data, and outputs the analog video data; and a liquid crystal display panel which displays an image by the use of analog video data based on the interior data during the no-signal period. | 06-14-2012 |
20140043317 | DISPLAY DEVICE AND METHOD OF DRIVING THE SAME - A display device including a display panel including gate and data line that cross each other; a first control signal generation unit generating a source output enable signal and a first gate output enable signal in synchronization with a data enable signal modulated according to a spread frequency clock signal; a second control signal generation unit starting to count a number of clocks of a fixed-frequency clock signal based on a point of time at which a first state of the source output enable signal ends, and outputting a second gate output enable signal when the counted number of the clocks becomes equal to a reference value; and a gate driving unit controlling an outputting of a gate signal to the gate lines using the second gate output enable signal. | 02-13-2014 |
20150071284 | APPARATUS FOR TRANSMITTING ENCODED VIDEO STREAM AND METHOD FOR TRANSMITTING THE SAME - Discussed is an apparatus for transmitting an encoded video stream, comprising: a slice generating unit that divides a frame, comprised in a video stream, into at least one or more slice; and a transmitting unit transmitting the slice in units of a packet within a slice deadline, which is a time limit required for transmission of the slice, the transmitting unit that preferentially transmits a header packet that contain a slice header information over other packets, and the slice header that comprises of information necessary for reconstructing the slice, wherein the transmitting unit comprises: a packet transmitter that retransmits the packet when the packet fails to be transmitted within the predetermined retry limit; and a header protector performing control for the header packet to be repeatedly transmitted within the slice deadline even when number of retransmissions of the header packet exceeds the predetermined retry limit. | 03-12-2015 |
20150071355 | APPARATUS AND METHOD FOR RECOVERING SPATIAL MOTION VECTOR - Discussed is an apparatus for recovering a motion vector to perform error concealment on received video stream, including: a first selecting unit selecting a first motion vector from a first slice that is above a lost slice, and selecting a second motion vector from a second slice that is below the lost slice; a second selecting unit determining at least one first orthogonal motion vector that is orthogonal to the first motion vector, and determining at least one second orthogonal motion vector that is orthogonal to the second motion vector; and a recovering unit computing a lost motion vector, comprised in the lost slice, using a weighted average of valid motion vectors, wherein the valid motion vectors include at least one of the first motion vector, the second motion vector, the first orthogonal motion vector, and the second orthogonal motion vector. | 03-12-2015 |
