摘要： A method of driving a display panel that includes first and second display-regions includes: determining maximum luminance data among first data including first red data, first green data, and first blue data for the first display-region, calculating a threshold gray-level based on a luminance gain, a gray-level of the maximum luminance data, and a gamma value for the display panel, selecting a smaller value between the threshold gray-level and a maximum gray-level as a gain determination gray-level, calculating a compensation gain obtained by dividing the gain determination gray-level by the gray-level of the maximum luminance data, generating first compensated data by applying the compensation gain to the first data, displaying a first-image in the first display-region based on the first compensated data, and displaying a second-image in the second display-region based on second data including second red data, second green data, and second blue data for the second display-region.

摘要： A display device includes a display panel that includes a first light emitting region and a second light emitting region, each of which emits first color. A first partition wall is disposed on the display panel, which allows the first color light to be transmitted therethrough, and which has a first opening defined therein and that corresponds to the first light emitting region. A first light conversion pattern is disposed inside the first opening and converts the first color light into second color light having different color. A reflection pattern is disposed corresponding to an outer surface of the first partition wall and a top surface of the first partition. An organic material pattern is disposed on the top surface of the first partition wall and overlaps the reflection pattern. A first color filter is disposed on the first light conversion pattern and allows the second color light to be transmitted therethrough.

摘要： A display panel includes a display device layer including first to third light emitting areas and a non-tight emitting area and a light shielding member disposed on the display device laver. The light shielding member overlaps the non-light emitting area and includes light shielding openings corresponding to the first to third light emitting areas. A first portion of the light shielding member disposed between the first light emitting area and the second light emitting area has a first thickness at a first edge adjacent to the first light emitting area and a second thickness that is different from the first thickness at a second edge adjacent to the second light emitting area. A second portion of the light shielding member is disposed between the first light emitting area and the third light emitting area and has a uniform thickness.
