Abstract: In a method of operating a light field three-dimensional (3D) display device having an RGBG pixel structure, multi-view image data including RGB data at multiple points of view are received, RGB rearrangement data including R sub-pixel data, G sub-pixel data, and B sub-pixel data are generated from the multi-view image data by extracting two adjacent ones of the R sub-pixel data at a same pixel row at a same point of view, by extracting two adjacent ones of the G sub-pixel data at a same pixel row at different points of view, and by extracting two adjacent ones of the B sub-pixel data at a same pixel row at a same point of view, RGBG data are generated by performing RGB-to-RGBG data conversion on the RGB rearrangement data, and a 3D image is displayed using the RGBG data.

Abstract: A display panel includes a plurality of pixels including a first type pixel, a second type pixel, and a third type pixel, and a lens array disposed on a first surface of the display panel and having an inclination angle. The first type pixel and the second type pixel are disposed adjacent to each other in a second direction. The third type pixel is disposed adjacent to the first type pixel and the second type pixel in a first direction. A pitch of the third type pixel in the second direction is less than or equal to a sum of a pitch of the first type pixel in the second direction and a pitch of the second type pixel in the second direction.

Abstract: A method of manufacturing a meta-optical element includes propagating light with random phase distribution toward a light collecting surface, obtaining a simulation intensity of the light at the light collecting surface through simulation, generating an error function based on an error data which is a difference between the simulation intensity of the light and an ideal intensity of the light, obtaining an optimal phase distribution of the light which outputs a minimum function value of the error function by applying a gradient descent, and forming a meta-optical element that implements the optimal phase distribution.

Abstract: Disclosed is a display device. A display panel outputs a first image in a first mode and outputs a second image in a second mode. A switch lens array is placed on the display panel and outputs the first image as a two-dimensional (2D) image in the first mode and converts the second image into a three-dimensional (3D) image in the second mode. A driving controller receives an image signal, converts the image signal into 2D image data based on a reference gamma value, and converts the image signal into 3D image data based on a correction reference gamma value different from the reference gamma value. A driving controller includes a gamma selection unit that selects one correction gamma value among a plurality of correction gamma values as the correction reference gamma value depending on predetermined depth information of the 3D image.

Abstract: A display device includes a substrate, a first set of light emitting structures, a second set of light emitting structures, a diffraction layer, and a refraction pattern. The substrate includes a first region and a second region. The first set of light emitting structures overlaps the first region. The second set of light emitting structures overlaps the second region. The diffraction layer overlaps the first region without overlapping the second region. The refraction pattern overlaps the diffraction layer. The diffraction layer includes first-refractive-index members and second-refractive-index members that are alternately disposed. A refractive index of each of the first-refractive-index members is lower than a refractive index of each of the second-refractive-index members.
