摘要： 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.

摘要： A transparent display device includes a transparent display panel which displays an image, a scan driver which provides a scan signal to the transparent display panel, a data driver which converts image data into a data signal based on an application gamma curve, and which provides the data signal to the transparent display panel, a timing controller which controls the scan driver and the data driver, a luminance value compensator which calculates a perception luminance of the transparent display panel based on a luminance of incident light that is incident on the transparent display panel and a transmittance of the transparent display panel, and a gamma curve adjuster which adjusts the application gamma curve based on a reference gamma value of a reference gamma curve and the perception luminance of the transparent display panel.
