A guide robot can include a travel part to move the guide robot, a touch screen and a camera, a sensor to detect an approach of a user, and a voice reception part to receive a voice. The guide robot further includes a controller to display at least one digital signage while the guide robot is traveling, in response to detecting the approach of the user, stop the traveling of the guide robot and transition the camera from a deactivated state to an activated state, and detect a face and a face angle of the user. Also, in response to determining that the user intends to use the guide robot, the controller can trigger a voice conversation mode by activating the voice reception part, stopping the display of the at least one digital signage and outputting usage guide information for the voice conversation mode.

The embodiment relates to a quantum dot-polymer composite and a method for producing the same, wherein the quantum dot-polymer composite includes: a first phase made of a matrix resin; a second phase dispersed and distributed in the first phase, comprising a quantum dot, and having a spherical shape; and a micro scattering agent distributed in an interface between the first phase and the second phase along a surface of the second phase.

Method for quantum dot-polymer composite, quantum dot-polymer composite, light conversion film comprising same, backlight unit, and display device

A hybrid organic/inorganic quantum dot composite with high reliability is disclosed. The hybrid organic/inorganic quantum dot composite includes quantum dot, polymer resin, and silica, in which the silica is formed in the polymer resin, one end of the polymer resin forms a chemical bond with the quantum dot, and another end of the polymer resin includes a functional group capable of forming an additional chemical bond. The hybrid organic/inorganic quantum dot composite is resistant to moisture and oxygen permeation, and thus, it is not degraded easily by bonding oxygen and moisture to quantum dots even if moisture and oxygen permeate into the composite. The quantum dot composite may be used as a secondary raw material capable of being processed into another form while maintaining physical properties of quantum dots as a primary raw material.

Hybrid organic/inorganic quantum dot composite and method for preparing the same

A quantum dot-polymer complex and a method for preparing the same. The quantum dot-polymer complex includes a first phase formed of a matrix resin, a globular second phase dispersed in the first phase, the second phase including a quantum dot therein, and a third phase disposed along a surface of the second phase between the first and second phases.
