Abstract: A display apparatus is provided. The display apparatus includes a display panel, a first layer, a signal applying unit, and a controller. The display panel displays an image. The first layer is formed on a first surface of the display panel. A shape of the first layer is changed when a first signal is applied to the first layer. The signal applying unit applies the first signal to the first layer. The controller controls the display panel to display the image.

Abstract: A display device includes a display panel that emits light in response to a panel driving signal, a panel driver that provides the panel driving signal to the display panel, and a driving controller that receives an image signal at a current frame rate and controls driving of the panel driver based on the image signal and a control signal. The driving controller includes a comparing unit that compares a reference frame rate and the current frame rate and outputs a duty control signal when the current frame rate is less than the reference frame rate, a duty control unit that controls a current duty ratio of a current emission period of the display panel based on the duty control signal, and a luminance control unit that controls luminance of each of the pixels based on the current duty ratio.

Abstract: A display device includes: a display panel including a plurality of pixels; and a panel driver that drives the display panel at a target refresh rate different from a previous refresh rate. The panel driver includes: a comparator which compares a difference value between the previous refresh rate and the target refresh rate with a reference value generated by multiplying the previous refresh rate by a predetermined reference percentage; and a determiner which determines a final count of at least one compensation frame to be inserted between a previous driving frame operating at the previous refresh rate and a target driving frame operating at the target refresh rate when the difference value is not less than the reference value, where the final count is a total number of the at least one compensation frame, and a natural number.
