A circuit board includes a first body part, a second body part and a connection part. The first body part includes a first contact surface and has a multi-layered structure. The second body part includes a second contact surface, has a multi-layered structure, and includes a first signal line spaced apart from the second contact surface. The connection part includes a third contact surface between the first contact surface and the second contact surface, and connects the first body part and the second body part to each other.

Circuit board and a display device including the same

A circuit board for a display device includes: a signal line to transmit signal, a first metallic layer overlapping the signal line, a first conductive layer spaced apart from the first metallic layer, a base layer insulating the signal line from the first metallic layer and from the first conductive layer, and a first capacitor including a first terminal electrically coupled to the first metallic layer and a second terminal electrically coupled to the first conductive layer.

Circuit board and display device including the same

A display device includes: a display panel to display an image; a signal controller to determine whether an input image signal is a still image signal, and if the input image signal is a still image signal, further determine whether image switching occurs, and if image switching occurs, to compensate image data according to frame data after the image is switched by using data values of two pieces of frame data between which the image switching occurs; and a data driver to generate a data signal based on the image data and to output the data signal to the display panel.

Display device and driving method thereof

A system for compensating for gamma data is provided comprising a display panel including at least one feedback line connected to at least one pixel, a gray voltage generator generating a reference gray voltage based on first gamma data, a data driver generating a data voltage based on the reference gray voltage and applying the generated data voltage to a data line, a multiplexer receiving at least one feedback voltage from the at least one feedback line and selecting a feedback voltage from the received at least one feedback voltage and outputting the selected feedback voltage, an A/D converter converting the selected feedback voltage into feedback data, and a signal controller storing the feedback data as feedback gamma data for the entire grays and compensating for the first gamma data based on the feedback gamma data.
