Abstract: Detecting a multi-path interference component in a time-of-flight (ToF) camera may be performed by generating a confidence map in which a distortion area attributable to a multi-path interference component included in a reflection modulation signals is specified, where the reflection modulation signals is generated when two modulation signals emitted from a light source to a subject return to the ToF camera after being reflected by the subject. Correcting the multi-path interference component corrects distortion attributable to a multi-path interference component, which may include correcting only the distortion area specified in the confidence map. Detecting the multi-path interference component in a ToF camera includes collecting the reflection modulation signal at a plurality of different times, calculating amplitudes and offsets of the collected reflection modulation signals, determining whether a multi-path interference component is included in the reflection modulation signal, and generating the confidence map.

Abstract: An apparatus for inspecting a display panel for defects includes a table which supports the display panel, a laser excitation unit that irradiates a non-display area of the display panel with a point laser beam, a thermal wave detecting unit that generates thermal wave images of irradiated portions of the non-display area, a driving unit, and a control unit. A groove corresponding to an edge of the display panel may be defined in a top surface of the table. A defect, such as a crack, may be detected by comparing a defect pattern obtained from the thermal wave images with a pre-registered defect pattern.

Abstract: A light emitting device is described, which has a first encapsulation film enclosing an outside and a top surface of a light emitting diode. The first encapsulation film comprises an organic thin film of a fluorine-based polymer and an inorganic material infiltrated into a void of the fluorine-based polymer and linked chemically to the fluorine-based polymer. Optionally, a second encapsulation film can be disposed between a substrate and the light emitting diode. The encapsulation film provides a moisture barrier, while being flexible. Since the encapsulation film provides improved barrier properties to moisture and the like, the light emitting device can maintain good current density, luminous efficiency and luminance. The light emitting device can be a display device, a lighting device, a touch screen, etc.
