Abstract: Discussed are a flexible thin film transistor (TFT) substrate, a flexible display panel and a flexible display device. The flexible TFT substrate of the present application can improve bending resistance of the flexible TFT substrate by arranging a concave structure in the bonding region and placing an organic material in the concave structure. When the bonding region is bent, a width of the bonding region can be reduced. Accordingly, a bezel width of the flexible display panel including the flexible TFT substrate is reduced, and a narrow bezel design is realized.

Abstract: A display panel is provided. The display panel includes a substrate, and a plurality of anodes, a pixel definition layer, a light-emitting layer, and a cathode layer that are laminated on the substrate. By collecting the anodes spaced apart from each other in a first direction in a same first pixel opening, number of the first pixel openings in the display area can be reduced, and number of ink droplets that can be sprayed within a single first pixel opening can be increased, so that a risk of bridging between adjacent ones of pixel openings can be lowered.

Abstract: A display panel and a display device are provided. The display panel includes a first optical refraction layer and a second optical refraction layer. The first optical refraction layer includes a plurality of openings. The second refraction layer is filled in the plurality of openings. A refractive index of the second optical refraction layer is greater than a refractive index of the first optical refraction layer. Furthermore, nanoparticles are further disposed in the second optical refraction layer. When light passes through, the first optical refraction layer and the second optical refraction layer can effectively improve transmittance rates of the light. Meanwhile, the nanoparticles can further act on the light, thereby effectively increasing a light extraction rate of the display panel and improving display effect of the display panel.

Abstract: The present invention relates to a display panel and a manufacturing method of the display panel. A charge generation layer of the present invention is produced using a mixture of an n-type organic material, a p-type organic material, and a polar solvent. The n-type organic material and the p-type organic material are mixed to form the charge generation layer, so that a contact area between the n-type organic material and the p-type organic material is increased. Accordingly, the present invention improves the transfer efficiency of charges, improves chances of separation of electrons and holes, and finally improves the charge generation efficiency of the charge generation layer. Therefore, the present invention avoids the use of a fine metal mask (FMM) in an evaporation process. Consequently, the present application reduces production costs and can be used in large-size-screen G8.6 production lines.
