摘要： A display device includes a display panel including gate lines, data lines, and pixels connected to the gate lines and the data lines and a driving circuit which controls the display panel in response to an image signal, a control signal, and a mode signal from an outside to display an image through the display panel. The driving circuit converts the image signal to data voltage signals corresponding to a first gamma curve to apply the data voltage signals to the data lines when the mode signal represents a normal mode and converts the image signal to data voltage signals corresponding to a second gamma curve different from the first gamma curve to apply the data voltage signals to the data lines when the mode signal represents a frequency variable mode.

摘要： A display apparatus includes: a top substrate over a bottom substrate and including a first region; a second-color color filter layer on a bottom surface of the top substrate and having a 2-1st opening exposing the first region; a first-color color filter layer including a portion in the 2-1st opening and a portion on a bottom surface of the second-color color filter layer; a bank between the first-color and the second-color color filter layers and the bottom substrate, the bank having a first opening corresponding to the first region, the first opening including a 1-1st portion overlapping the 2-1st opening and a 1-2nd portion outside the 2-1st opening; a first-color quantum dot layer in the first opening; and a first reflective layer on an inner surface of the first opening and a portion of a top surface of the first-color quantum dot layer.

摘要： A display apparatus including a light emitting device layer emitting a first light having a peak wavelength of 500 nm or less, a color control layer disposed on the light emitting device layer, the color control layer including an emitting element converting the first light, a color filter layer disposed on the color control layer, and an absorptive scattering element provided in or on the color control layer. The absorptive scattering element may include a light absorbing portion, in which absorptivity of a green or red light is greater than absorptivity of the first light. Accordingly, reflectance of the display apparatus to an external light may be reduced.
