20090144641 | LIQUID CRYSTAL DISPLAY AND DISPLAY SYSTEM COMPRISING SAME - A liquid crystal display (LCD) monitor having an LCD screen is provided in a display system where the monitor is coupled to a host device by way of serial data links such as VESA DisplayPort links. The LCD monitor uses a first bi-directional serial channel (e.g., AUX_CH) to send an OSD (on-screen display) image-requesting control signal to the host device. The host device uses a first unidirectional serial channel (e.g., Main link) to return a corresponding OSD video signal to the monitor. The monitor includes a handling portion for providing a user command signal in response to user manipulation of on-monitor inputs, and a timing controller for receiving the user command signal and outputting a corresponding OSD image-requesting control signal through the first bi-directional channel to the host device. The timing controller receives the corresponding OSD video signal from the host and produces a corresponding OSD image on the LCD screen. | 06-04-2009 |
20090174691 | TIMING CONTROLLER, DATA PROCESSING METHOD USING THE SAME AND DISPLAY APPARATUS HAVING THE SAME - A timing controller includes a receiver and a clock generator connected to output terminals of the receiver. The clock generator receives an external clock signal through the receiver and periodically modulates a frequency of the external clock signal to generate a modulation clock signal that is used to process a plurality of pixel data. The clock generator controls a delay time of the modulation clock signal based on a modulation rate of the frequency of the modulation clock signal. According to the timing controller, circuit blocks connected to output terminals of the clock generator are operated by the modulation clock signal. Thus, the circuit blocks operated by the delayed modulation clock signal may be prevented from malfunction due to electromagnetic interference. | 07-09-2009 |

20110148841 | DRIVING CIRCUIT AND DISPLAY APPARATUS HAVING THE SAME - A driving circuit includes; a timing controller, a first gamma reference voltage generating circuit, and a data driver. The timing controller receives an external signal to output an image signal and a control signal for a single frame. The first gamma reference voltage generating circuit outputs first, second, third and fourth gamma reference voltages. The data driver includes a second gamma reference voltage generating circuit, a digital-to-analog converter and a selector. The second gamma reference voltage generating circuit outputs at least one fifth gamma reference voltage and at least one sixth gamma reference voltage based on the control signal. | 06-23-2011 |
20110298768 | APPARATUS AND METHOD FOR DRIVING DISPLAY DEVICE - A driving apparatus of a display device, comprises a signal controller which receives an image signal and an input control signal from an outside, a signal error judgment unit which judges an error of the input control signal, and a data driver and a gate driver which receive a signal output from the signal controller, wherein the signal error judgment unit does not judge an error of the input control signal during a predetermined error judgment holding time after the error of the input control signal is generated and judges the error of the input control signal at the substantially a same time as when the error judgment holding time is terminated when the error of the input control signal is continued after the predetermined error judgment holding time. | 12-08-2011 |
20120249522 | METHOD OF PROCESSING THREE-DIMENSIONAL IMAGE DATA AND A DISPLAY APPARATUS FOR PERFORMING THE SAME - A method of processing three-dimensional image data includes demodulating a first transmission signal into image data which is image data for a left-eye or image data for a right-eye, wherein the first transmission signal is received during an enable period of a frame; demodulating a second transmission signal into identification data, where the second transmission signal is received during a blanking period of the frame, and the identification data identifies the image data of a subsequent frame; identifying whether the image data of the subsequent frame is the image data for the left-eye or the image data for the right-eye based on the identification data; and processing the image data based on an identified result from the identifying whether the image data of the subsequent frame is the image data for the left-eye or the image data for the right-eye. | 10-04-2012 |
20120249605 | LIQUID CRYSTAL DISPLAY DEVICE AND METHOD FOR DRIVING THEREOF - A liquid crystal display includes: a liquid crystal panel including a first region and a second region; a first signal controller which generates a first representative value representing image signals of the first region; a second signal controller which generates a second representative value representing image signals of the second region and transmits the second representative value to the first signal controller; a light source unit which irradiates light to the liquid crystal panel; and a light source driver which controls luminance of the light source unit. The first signal controller transmits a luminance of the light source unit to the light source driver. The luminance of the light source unit is calculated from the first representative value and the second representative value. | 10-04-2012 |
