Abstract: The present disclosure provides a display device and a manufacturing method thereof. The display device includes an imaging area and a display area on at least one side of the imaging area. The imaging area includes: a substrate; an image collection device on a side of the substrate, the image collection device including a photosensitive element and an optical element; a light blocking layer on a side of the substrate away from the image collection device, wherein the light blocking layer includes at least one of a light absorbing layer or a diffuse reflection layer, and the light blocking layer is provided with a first gap; and a plurality of first electrodes on a side of the light blocking layer away from the substrate, wherein a second gap is provided between two adjacent first electrodes of the plurality of first electrodes.

Abstract: A radiation therapy system is disclosed. The radiation therapy system includes a gantry, a first radiation source, and a second radiation source. The gantry is configured to have a cavity extending in a direction along a rotation axis, and the cavity is configured to house a target object. The first radiation source is mounted on the gantry, and configured to emit a treatment beam to a treatment area of the target object. The second radiation source is mounted on the gantry, and configured to emit an imaging beam to an imaging area of the target object. The treatment area partially overlaps the imaging area. A rotation plane of the first radiation source and a rotation plane of the second radiation source are distributed in a direction along the rotation axis.

Abstract: A single piece-type bipolar film roll with a mesh cloth support and a manufacturing method therefor. The single piece-type bipolar film roll is supported by a high-strength ultra-high molecular weight polyethylene mesh cloth, one side of the single piece-type bipolar film roll is a cation exchange layer containing a benzenesulfonic acid group, the other side of the single piece-type bipolar roll is an anion exchange layer containing a benzyl dimethyl butyl ammonium quaternary amino group, and the middle is a water dissociation catalyst layer containing a benzyl methyl butyl amine tertiary amino group, and the three layers form the single piece-type bipolar film roll.

Abstract: A multi-directional scrolling wheel for an input device includes a housing and a carrier supported within the housing. The carrier has a wheel can be rotated freely so as to scroll an image on a display in a Y-axis direction. The carrier can be tilted left and right so as to scroll the image on the display in an X-axis direction.

Abstract: It is an object of the present invention to provide a production method of 2,4,5-trialkylbenzaldehyde from 1,2,4-tribenzaldehyde at low cost and safely. The present invention provides a production method of a 2,4,5-trialkylbenzaldehyde which comprises carbonylating a 1,2,4-trialkylbenzene with carbon monoxide in the presence of a catalyst, said catalyst comprising trifluoromethanesulfonic acid.
