Description

Display device and electronic device including the same The present invention relates to a display device and an electronic device including the same. The display panel includes a transmissive display panel that selectively transmits source light generated from a light source, and an emissive display panel that generates source light within the display panel itself. The display panel may include different types of light control patterns depending on the pixels to generate a color image. The light control patterns may transmit only a portion of the wavelength range of the source light or change the color of the source light. Some light control patterns may change the characteristics of the light without changing the color of the source light. FIG. 1 is a perspective view of a display device of one embodiment. FIG. 2 is an exploded perspective view of an electronic device of one embodiment. Figure 3 is a block diagram of the electronic device shown in Figure 2.

For example, without departing from the scope of the present invention, the first component may be named the second component, and similarly, the second component may be named the first component. A singular expression may include a plural expression unless the context clearly indicates otherwise. Additionally, terms such as "below," "lower side," "above," and "upper side" are used to describe the relationships between the components depicted in the drawings. These terms are relative concepts and are described based on the directions indicated in the drawings. Terms such as "include" or "have" are intended to specify the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.
