The present disclosure relates to a physically pretreated biomass composition, which enables chemical treatment in a biomass composition comprising a high concentration of a biomass substrate, and a preparation method thereof. Through specific physical pretreatment (attrition milling) of herbaceous biomass, the physically pretreated biomass composition has fluidity/flowability at a substrate concentration of biomass of 20% (w/w) (biomass:solvent=1:4) or above, and thus the pretreatment cost may be reduced, and it is very useful in biomass treatment processes.

Physically pretreated biomass composition comprising a high concentration of biomass

A digital signage including a display panel configured to display content; a controller configured to: display first content in a first area of the display panel, obtain display panel control data for preventing an afterimage, based on received afterimage-related data, and move the display panel a predetermined amount and display the first content in a second area of the display panel based on the display panel control data.

Digital signage and operating method thereof

A digital signage including a memory; a display; and a controller configured to display content on the display, capture a plurality of images of the displaced content, store the plurality of captured images in the memory, and display the stored images on the display in response to an error event signal.
