Abstract

A display device comprises a substrate including a subpixel including a light-emitting layer and a light-sensing pixel including a light-receiving layer, a first light-receiving meta-lens disposed on the light-receiving layer, and a second light-receiving meta-lens disposed on the first light-receiving meta-lens, wherein light incident on the first light-receiving meta-lens is emitted at a first light-receiving angle with respect to the normal of the substrate, and light incident on the second light-receiving meta-lens is emitted at a second light-receiving angle with respect to the normal of the substrate, and the first light-receiving angle is greater than the second light-receiving angle.

Description

Display device and electronic device including the same The present invention relates to a display device and an electronic device including the same. With the recent rise in interest in information displays, research and development on display devices is continuously being carried out. FIG. 1 is a block diagram schematically showing an embodiment of a display device. FIG. 2 is a block diagram schematically showing an example of a subpixel. FIG. 3 is a plan view schematically showing an example of a display panel. Figure 4 is a plan view schematically showing an example of a pixel. Figures 5 and 6 are cross-sectional views along the line AA' of Figure 4. Figure 7 is a cross-sectional view schematically showing a light-sensing pixel. Figure 8 is a cross-sectional view schematically showing the second pixel. FIG. 9 is a cross-sectional view schematically showing the first pixel. FIG. 10 is a perspective view schematically showing an example of an application of a display device. Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings. It should be noted that in the following description, only the parts necessary for understanding the operation according to the present invention are described, and the description of other parts is omitted to avoid obscuring the gist of the present invention. The present invention is not limited to the embodiments described herein and may be embodied in other forms. However, the embodiments described herein are provided merely to explain in detail sufficient for a person skilled in the art to easily implement the technical concept of the present invention. Throughout the specification, when a part is described as being "connected" to another part, this includes not only cases where they are "directly connected," but also cases where they are "indirectly connected" with other elements interposed between them. The terms used herein are intended to describe specific embodiments and are not intended to limit the invention. Throughout the specification, when a part is described as "comprising" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. "At least one of X, Y, and Z" and "at least one selected from the group consisting of X, Y, and Z" may be interpreted as one X, one Y, one Z, or any combination of two or more of X, Y, and Z (e.g., XYZ, XYY, YZ, ZZ). Here, "and/or" includes all combinations of one or more of such components. Herein, terms such as first, second, etc. may be used to describe various components, but these components are not limited to these terms. These terms are used to distinguish one component from another. Accordingly, the first component may refer to the second component to the extent that it does not depart from what is disclosed herein. Spatially relative terms, such as "below" and "above," may be used for descriptive purposes to explain the relationship between one element or feature and other element(s) or feature(s) as depicted in the drawings. Spatially relative terms are intended to include different directions during use, operation, and/or manufacturing in addition to the directions depicted in the drawings. For example, if the device depicted in the drawings is inverted, elements described as being located "below" other elements or features are located in the direction "above" of other elements or features. Thus, in one embodiment, the term "below" may include both directions of up and down. Furthermore, the device may face other directions (e.g., rotated 90 degrees or in other directions), and accordingly, the spatially relative terms used herein are interpreted accordingly. Various embodiments are described with reference to drawings illustrating ideal embodiments. Accordingly, it will be expected that the shapes may vary, for example, depending on tolerances and/or manufacturing techniques. Therefore, the embodiments disclosed herein should not be interpreted as being limited to the specific shapes depicted, but should be interpreted to include, for example, variations in shapes resulting from manufacturing. As such, the shapes depicted in the drawings may not depict the actual shapes of the regions of the device, and the embodiments are not limited thereto.
