Abstract: A display panel is provided. In the display panel, color resists are disposed in light-emitting regions and correspond to light-emitting pixels, and overlapping color resists are disposed in non-light-emitting regions, so as to replace polarizers. This increases a light transmittance of the display panel, reduces a reflectivity of the display panel, and reduces a thickness of the display panel. Furthermore, because the overlapping color resists are used to replace a black matrix in the non-light-emitting regions, process steps are reduced.

Abstract: The present application provides an OLED display panel and an OLED display panel manufacturing method forming at least one crack-proof recess surrounding a display region on an array substrate. When the OLED display panel performs a laser cutting process to a cutting line region on the array substrate, cracks generated from the cutting line region is interrupted by the crack-proof recess and therefore cannot extend into a deep inside of a non-display region, and cannot further extend into the display region, which prevents a technical issue of a lowered yield rate due to extension of cracks into the display region.

Abstract: A display panel and a mobile terminal are disclosed in the present disclosure. The display panel includes a substrate and a pixel driving circuit layer. The pixel driving circuit layer includes a plurality of pixel driving circuits, and each of the pixel driving circuits at least includes a compensation transistor and a shielding component. An orthogonal projection of the shielding component projected on the substrate at least partially overlaps an orthogonal projection of the compensation transistor projected on the substrate, so that the compensation transistor is not affected by a potential of the substrate, thereby enhancing the reliability of currents of the pixel driving circuits.

Abstract: The present invention provides a display panel and a display device. A first gate electrode and a first polar plate of a first thin film transistor are used to constitute a storage capacitor. At a same time, the first polar plate and a second gate electrode of a second thin film transistor are disposed in a same layer. Therefore, a gate insulation layer used to separate the first polar plate from the first gate electrode and the second gate electrode in layers can be omitted, so as to reduce a number of film layers in the display panel and a thickness of a film laminated structure, thereby reducing a complexity of a process flow of the display panel, and improving bending ability of the display panel.

Abstract: A display module includes a display function layer, a display planar area, and a buffer layer. The display function layer is divided into a display segment, a compression segment, and a bending segment therebetween. The display planar area includes a compression overlapping area. A positive projection of the compression segment on the display segment covers the compression overlapping area. The buffer layer covers the compression overlapping area and is disposed on a side of the display function layer away from an eminent layer of the display function layer. The buffer layer comprises a metal layer. A protective layer is disposed on a side of the buffer layer away from the display function layer. The protective layer covers the compression overlapping area. A hardness of a material for the protective layer is greater than a hardness of a material for the metal layer.
