Abstract: A display panel (20), a display device and a debugging method thereof are provided. The display panel (20) includes: a base substrate (1), including a display region (A) and a non-display region (B) surrounding the display region (A). the non-display region (B) including a binding region (C) located on one side of the display region (A); and a plurality of sub-pixels (2), located in the display region (A). Areas of pixel aperture regions of the plurality of sub-pixels (2) tend to increase in a direction from the binding region (C) to the display region (A).

Abstract: The present disclosure provides a lens assembly, including: a lens barrel; a lens group with an optical axis accommodated in the lens barrel; a pressure ring arranged on an image side of the lens group and abutting against the lens group; and an optical filter abutting the pressure ring; where the pressure ring includes a first outer wall and an adhesive storage groove connected to the first outer wall and close to the image side; the lens assembly further comprises an adhering part, where the optical filter and the inner wall are arranged to space apart from each other to form an adhesive filling channel, and the adhering part fills the adhesive filling channel and is connected to the adhesive storage groove, the platform part, the inner wall and the optical filter. Compared with the related art, the above-mentioned lens assembly has a large overall thrust and good reliability.

Abstract: The invention relates to a ultraviolet anti-counterfeiting check verification method which solves subjective defect and time consuming problems of the traditional verification methods, and comprises the following steps: a. collecting ultraviolet gray level image by a ultraviolet scanner; b. extracting a first binary image from the ultraviolet gray level image; c. calculating a tilt angle of the first binary image; d. calculating tilt correction positions of pixels of the ultraviolet gray level image and the first binary image; e. determining a top left corner locating position of a first binary image rectangle; f. extracting a second binary image from the tilt corrected ultraviolet gray level image; g. performing position correction on the second binary image of a check to be verified; and h. calculating the matching degree between the second binary image of the check to be verified and a second binary image of a real check to verify authenticity.

Abstract: The invention relates to an automation technology.
