Abstract: A backlight and a display device are provided herein, which is related to the field of display technology and intends to improve visual effect of the image displayed by the display device. The backlight may include a back plate, a light guide plate and a light source. The back plate includes an accommodation groove, and the light guide plate includes a holding groove at a first side surface of the light guide plate. The light source includes at least one light emitting element. The holding groove is configured to hold at least a portion of the at least one light emitting element, and the accommodation groove is configured to accommodate the light guide plate and the light source.

Abstract: A flexible display device and an electronic device are provided. The flexible display device includes a display substrate, a polarizer and a first optical adhesive layer that are sequentially stacked, and is provided with a display area and a first corner area. In the first corner area, an outer contour of the polarizer and/or an outer contour of the first optical adhesive layer extend(s) beyond an outer contour of the display substrate. The display substrate includes an anti-crack base, an anti-crack retaining wall, and a plurality of anti-crack blocks that are at least located in the first corner area. The anti-crack retaining wall is formed on the anti-crack base and located outside of the display area, and the plurality of anti-crack blocks are formed on the anti-crack base and located on the side of the anti-crack retaining wall away from the display area.

Abstract: Disclosed are a method for eliminating self-magnetization of a mask, a method for manufacturing a substrate and a mask testing device. The mask may include a plurality of metal stripes spaced from each other. The method may include a step of: energizing the mask, so as to enable the plurality of metal stripes to carry like charges, thereby separating every metal stripe from other adjacent metal stripes bonded together.
