Description

Display device The present application claims priority and ownership rights obtained from korean patent application No. 10-2020-0096230 filed on 7/31/2020, the contents of which are incorporated herein by reference in their entirety. Technical Field Embodiments of the present invention relate to a display device. Background With the development of information technology, importance of a display device as a connection medium between a user and information has been attracting attention. In response to this, the use of display devices such as liquid crystal display devices and organic light emitting display devices is increasing. When the display device displays a moving image, it can display the image at a high frequency so as to smoothly represent the movement. In contrast, when the display device displays a still image, there is no motion, and thus no problem may occur even if the image is displayed at a low frequency. In addition, when the display device displays an image at a low frequency, it is advantageous in terms of power consumption. Disclosure of Invention However, when the display frequency of the display device is switched from a high frequency to a low frequency, flicker can be visually recognized because the period of the brightness decrease changes. In addition, when the display device is driven at a low frequency, flickering may occur when a specific pattern is displayed. The technical problem to be solved is to provide a display device capable of preventing visual recognition of flicker when a display frequency is switched from a high frequency to a low frequency. In addition, the technical problem to be solved is to provide a display device capable of preventing flicker from occurring when a specific pattern is displayed during low frequency driving.
