20090295768 | DISPLAY DEVICE AND METHOD OF DRIVING THE SAME - A display device with improved display quality and a method of driving the display device set at least one static area in each of a previous frame and a current frame by comparing edge areas of the previous frame and edge areas of the current frame, and create an interpolated frame for display between the previous and current frames. At least one static area of the previous frame is used in an unmodified state as a static area of the interpolated frame. | 12-03-2009 |

20100007648 | DRIVING APPARATUS AND DISPLAY DEVICE INCLUDING THE SAME - The present invention relates to a driving device for a liquid crystal display and a driving method thereof. A signal controller of the driving device generates a data signal according to an input image signal input to the display device, generates a clock signal according to the input control signal, and generates a differential pair image signal by modulating the clock signal to the data signal. Here, a data signal period of the differential pair image signal and a clock signal period are converted with a different level and are output. A data driver of the driving device receives the differential pair image signal, divides the data signal and the clock signal from the differential pair image signal, and generates a data voltage by sampling a data signal by using the clock signal. | 01-14-2010 |
20100039416 | METHOD OF DRIVING DISPLAY APPARATUS AND DRIVING CIRCUIT FOR DISPLAY APPARATUS USING THE SAME - In a driving method of a display apparatus using a driving circuit, when an image signal is a film image signal, first, second, and third original image signals are extracted based on the film image signal. Then, a first compensation image signal is generated based on first and second original image signals, and a second compensation image signal is generated based on second and third original image signals. The first original image signal, the first compensation image signal, the second original image signal, and the second compensation image signal are sequentially output to have a driving frequency higher than an input frequency. In addition, the first original image signal, the first compensation image signal, the second original image signal, and the second compensation image signal are output i, k, j, and k times, respectively. Thus, a trembling phenomenon perceived by a viewer of a film image may be prevented. | 02-18-2010 |
20100149148 | DISPLAY DEVICE AND METHOD OF DRIVING THE SAME - A method of driving a display device includes: sub-sampling an original image signal; generating a sub-image signal; generating a sub-interpolated image signal from the sub-image signal; generating an interpolated frame by realigning the sub-interpolated image signal; and displaying an image having the interpolated frame. | 06-17-2010 |
20100225674 | METHOD OF DRIVING A LIGHT SOURCE, LIGHT SOURCE APPARATUS FOR PERFORMING THE METHOD AND DISPLAY APPARATUS HAVING THE LIGHT SOURCE APPARATUS - A method of driving a light source including a light-emitting block includes generating a luminance representative value based on an average grayscale value and a maximum grayscale value extracted from an image signal corresponding to the light-emitting block. The method further includes detecting a predetermined pattern of the light-emitting block, generating a compensation control signal based on the predetermined pattern, generating a compensated luminance representative value by compensating the luminance representative value based on the compensation control signal, and driving the light-emitting block based on the luminance level of the light-emitting block corresponding to the compensated luminance representative value. | 09-09-2010 |
20100277490 | IMAGE DRIVING APPARATUS AND DISPLAY APPARATUS INCLUDING THE SAME - A wireless and multi-channel re-transmitting link is provided between an image displaying part that is housed in a first housing and an image data processing part that is housed in a segregated second housing. The wireless link allows the image displaying part to be more easily moved around and to be made lighter and slimmer in profile because at least some image data processing can be carried out in the second housing and yet cumbersome cables are not needed for linking the pre-processed image data from the second housing to the first housing. In one embodiment, the data bandwidth. that is to he transmitted through the wireless link is first reduced; for example the frame refresh rate of image frames conveyed through each of the wireless channels is made less than the frame refresh rate of the original image signal. In one embodiment, the reduced number of frames per unit time are further frequency wise and temporally wise spaced apart from one another by alternatingly sending them through different wireless channels at different times. Thus if a burst of noise strikes one of the plural re-transmission channels, the likelihood that it will corrupt a frame is reduced. | 11-04-2010 |
