Abstract: Provided is a display panel. The display panel includes: a display substrate, provided with a display region and a peripheral region surrounding the display region; and a touch layer laminated on the display substrate, wherein the touch layer includes a plurality of touch electrodes and a plurality of traces, orthographic projections of the plurality of touch electrodes on the display substrate being within the display region, and orthographic projections of the plurality of traces on the display substrate being within the peripheral region.

Abstract: The present invention discloses a display defect detection method, apparatus, and device for a display screen. The method includes: identifying a suspected defective pixel from a first image of a front side of a tested display screen, where the first image is shot when the tested display screen is in a solid-color display state; identifying an external smudgy pixel from a second image of the front side of the tested display screen, where the second image is shot when the tested display screen is in a die-out state and the front side is illuminated by a diffuse reflection light source; detecting, for each suspected defective pixel identified from the first image, whether a pixel at a same location in the second image is the external smudgy pixel; and if no, determining the suspected defective pixel as a display defective pixel.
