Abstract

The invention discloses a flexible display device and a method of operating the flexible display device. The flexible display device includes a flexible display panel that includes a display region, a gamma data storage that stores entire driving gamma data generated by a first multi-time programming for an entirety of the display region, and partial driving gamma data generated by a second multi-time programming for a portion of the display region, a gamma reference voltage generator that generates a gamma reference voltage based on the entire driving gamma data when the flexible display panel is not deformed, and generates the gamma reference voltage based on the partial driving gamma data when the flexible display panel is deformed, and a data driver that provides data voltages to the flexible display panel based on the gamma reference voltage.

Description

technical field [0001] The present disclosure relates to a display device, and in more detail, to a flexible display device and a driving method of the flexible display device. Background technique [0002] Recently, flexible display devices such as foldable display devices and rollable display devices in which at least a region of the display panel can be deformed have been developed. This kind of flexible display device can be deformed so that a part of the display panel area is seen by the user but the remaining area of ​​the display panel is not seen by the user. At this time, in order to reduce power consumption, the flexible display device may only drive a part of the display panel viewed by the user. However, when the flexible display device drives only a part of the display panel, compared with driving the entire area of ​​the display panel, the load on the display panel is reduced, and the brightness of the display panel may be higher than a desired brightness leve...
