Abstract: A display substrate includes an underlaying substrate, a display structure layer arranged on the underlaying substrate, and a light regulation layer arranged at a light exiting side of the display structure layer. The display structure layer includes multiple sub-pixels. An orthographic projection of the light regulation layer on the underlaying substrate does not overlap with opening regions of the multiple sub-pixels. The light regulation layer is configured to adjust an emergent direction of light of at least one color emitted from the display structure layer.

Abstract: Provided is a method for manufacturing a display panel. First, the method includes sequentially preparing an anode layer and a first pixel define layer on a side of a substrate layer, then coating an organic light-induced material on a first surface, distal from the anode layer, of the first pixel define layer, and forming a polymer film layer by reacting the first pixel define layer with the organic light-induced material under a predetermined condition, and then preparing an organic functional layer and a cathode layer on a surface, distal from the first pixel define layer, of the organic light-induced material. The organic light-induced material at least contains a hydroxyl group and an unsaturated carbon-carbon double bond.

Abstract: A substrate cleaning device includes: a housing having a cleaning chamber therein; a plurality of spray pipelines pivotally mounted at the housing and distributed side by side along a moving direction of a substrate, each of the spray pipelines is provided with several spray ports configured to direct liquid in the spray pipeline towards a surface to be cleaned of the substrate, and one end of each of the spray pipelines is provided with a transmission gear coaxially fixed thereto; a driving system (4) coupled with the transmission gear and thus configured to drive the spray pipeline, through the transmission gear, to rotate reciprocally at the same frequency, wherein a portion of spray pipelines have a reciprocal rotation direction opposite to that of the other portion of spray pipelines. This substrate cleaning device enables a better cleaning effect for the substrate surface with minimum influence on the traveling speed of the substrate.
