Abstract: A receiving circuit includes a first capacitor connected to a first signal line, a second capacitor connected to a second signal line. A first bias control circuit may convert a common mode voltage of a first received signal provided through the first capacitor to a first voltage level to output a first biased signal. A second bias control circuit may convert a common mode voltage of a second received signal provided through the second capacitor to a second voltage level to output a second biased signal. A balance compensation circuit may receive the first biased signal and the second biased signal, compensate for an offset voltage of the first biased signal based on the second biased signal, and compensate for an offset voltage of the second biased signal based on the first biased signal to output a first differential signal and a second differential signal.

Abstract: A display device includes a display panel which includes gate lines and data lines, a gate driver electrically connected to the gate lines, a temperature sensor which includes at least three temperature sensing circuits which are disposed adjacent to the gate driver, and a voltage generating circuit which outputs a test voltage to each of the temperature sensing circuits and outputs a clock signal, which is compensated based on a result voltage having a lowest voltage level among result voltages provided from the temperature sensing circuits, to the gate driver.

Abstract: A display device includes a display panel including gate lines, data lines, and pixels individually connected to a corresponding gate line and data line, a gate driver driving the gate lines, a data driver driving the data lines, and a driving controller. The driving controller receives, from an external source, first image signals and a variable frequency signal indicating an operation frequency (frame rate) for the display device. The driving controller converts the first image signals to second image signals by adding a compensation value corresponding to the operation frequency to the first image signals, and outputs the second image signals to the data driver. Embodiments may compensate for luminance reduction/variation and reduce image artifacts that otherwise occur due to variable frequency operation. An alternative embodiment dynamically controls an amount of light output from a backlight according to the variable frequency signal.

Abstract: There is provided a display apparatus comprising: a backlight configured to output a first and a second light having a first and second color during a first and second field of a frame; a mapper configured to map an input image signal into a first and a second mapping data corresponding to the first and second light; a compensator configured to compensate a first and a second color mapping data on a basis of a first and a second DCC compensation data so as to generate a first and second color output image data; and a liquid crystal panel comprising a transmissive sub pixel configured to modulate the first and second light on a basis of the first and second color output data to display a first image having the first color and a second image having the second color.
