Abstract: A display device includes a display panel including a plurality of pixels; a gate driver for applying a gate-on signal through a plurality of gate lines of the display panel; a data driver for applying a data signal through a plurality of data lines of the display panel; and a timing controller for controlling the gate driver and the data driver to display an image frame at a first frame frequency. The display panel is driven at a second frame frequency that is higher than the first frame frequency. The timing controller controls the gate-on signal to be applied to the plurality of gate lines for a time determined on the basis of the second frame frequency, and controls the data driver to apply an over driven data signal to the plurality of data lines.

Abstract: Disclosed are an electronic device and a controlling method of an electronic device. In particular, electronic device includes: a display panel divided into a plurality of regions; a panel driver configured to control driving of the display panel; a plurality of timing controllers configured to control the panel driver, each including two ports disposed in opposite directions, connected to each other through the two ports, and each corresponding to each of the plurality of regions; and a first processor configured to transmit a signal in a first direction through the plurality of timing controllers, wherein the plurality of timing controllers are configured to identify input/output directions of the two ports included in each of the plurality of timing controllers that correspond to the first direction in case of receiving a first signal including image data and a control instruction for transmitting the image data in the first direction from the first processor; and transmit the first signal in the first direction through the two ports included in each of the plurality of timing controllers and having the input/output directions identified as corresponding to the first direction. Various other embodiments are possible.
