Abstract: A display device includes first and second light emitting regions; first and second pixel electrodes in the first and second light emitting regions, respectively; a first organic layer in the first light emitting region, including first and second light emitting layers; a second organic layer in the second light emitting region, including a third light emitting layer; a common electrode on the first and second organic layers; a wavelength conversion pattern on the common electrode, overlapping the first organic layer, and wavelength-converting light of a first color into light of a second color, different from the first color; and a light transmitting pattern on the common electrode, overlapping the second organic layer. The third light emitting layer and one of the first and second light emitting layers emit light of the first color, and another one of the first and second light emitting layers emits light of the second color.

Abstract: There is disclosed a posture analysis system using a smart mirror and a camera. The posture analysis system includes a smart mirror configured to reflect a posture of a user, a camera module configured to photograph the posture of the user and generate a posture image, a posture recognition module configured to recognize the posture image generated by the camera module, an image storage control module configured to automatically perform control to store the posture image, an image storage module configured to store the posture image by automatic control of the image storage control module, and a user balance analysis module configured to perform a posture balance analysis of the user using the posture image stored in the image storage module. The posture analysis system described above is configured to photograph and analyze the user's original, uncorrected posture with the eyes closed, and thereby, has an effect of accurately analyzing postures of shoulders, pelvis, arms, legs, and the like of the user.

Abstract: Disclosed is an exercise rehabilitation system using a smart mirror.

Abstract: A content output system according to an embodiment of the present invention includes a web server for providing contents to be output to a web-connected terminal, and devices connected to the web server to output the contents, the devices respectively outputting a predetermined area of each content. The devices may be operated by a WebRTC. The devices may include a master device for generating and providing content synchronization information and a synchronization signal for specifying an output timing of the contents to be output, and at least one slave device for outputting the contents according to the content synchronization information and the synchronization signal provided from the master device. The master device and the slave device are set among the devices constituting the multi-vision so that the synchronization and synchronization between the multiple devices without a separate control terminal, thereby simplifying the system configuration and reducing the cost.

Abstract: A battery charging apparatus for an electric vehicle includes a first converter part configured to convert a first voltage, which is inputted with rectification, into a second voltage; and a second converter part configured to output a third voltage for charging a battery for the electric vehicle by converting the second voltage into a direct current. The output end of the first converter part comprises a first and a second output terminal. The second converter part comprises a first switching element connected with the first output terminal; a second switching element connected with the second output terminal; a first output capacitor serially connected with the first switching element; and a second output capacitor serially connected with the second switching element. The time during which the first switching element is turned on does not overlap the time during which the second switching element is turned on.
