摘要:
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.

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.

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.

A method of driving a display device includes sub-sampling an original image signal. The method further includes generating a sub-image signal, generating a sub-interpolated image signal from the sub-image signal, and generating an interpolated frame by realigning the sub-interpolated image signal. An image having the interpolated frame is then displayed.

A display device and a driving method thereof are disclosed. The display device includes a plurality of pixels arranged in a matrix with each pixel including first and second subpixels. First gate lines are connected to the first subpixel and transmit a first gate-on voltage, second gate lines are connected to the second subpixel and transmit a second gate-on voltage, and data lines are connected to the first and second subpixels and transmit first and second data voltages. The respective first and second data voltages that are applied to the first and second subpixels are obtained from the same image information, the first data voltage is not higher than the second data voltage, and the second data voltage is precharged in the data lines before applying the first data voltage to the first subpixel.

Driving apparatus for a display panel having a plurality of pixels includes a plurality of gate line sets connected to the pixels and transmitting a gate-on voltage to the pixels, a plurality of data lines connected to the pixels and transmitting a normal data voltage and an impulsive data voltage to the pixels, a signal controller for converting an input image data of a first gray to an output image data of a second gray and outputting the converted data, a data driver connected to the data line and applying the normal data voltage and the impulsive data voltage corresponding to the output image data to the data line, and a gate driver connected to the gate line and applying the gate-on voltage to the gate line according to a control of the signal controller. The normal data voltage is sequentially applied to a first gate line set among the plurality of gate line sets, and the impulsive data voltage is sequentially applied to a second gate line set among the plurality of gate line sets. The output image data of the second gray is determined in consideration of luminance display time of a pixel charged by the normal data voltage. Accordingly, luminance deterioration by different luminance display times for respective pixel rows connected to respective gate lines in the gate line set can be prevented.
