Abstract

The invention provides a display panel and a display terminal. The display panel comprises a substrate, a pixel definition layer and a light-emitting layer, the pixel definition layer and the light-emitting layer are arranged on the substrate, the pixel definition layer is provided with a plurality of openings, the light-emitting layer comprises a plurality of light-emitting units arranged in the openings, the pixel definition layer comprises a plurality of pixel dams, and at least part of the pixel dams comprise first parts and second parts. The second part is arranged on the side, away from the substrate, of the first part, the first part and the second part form a step, and the opening size corresponding to the first part is smaller than that corresponding to the second part; according to the display panel, the pixel dam comprises the first part and the second part, and the size of the opening formed by the first part and the second part is reduced along the light emitting direction of the display panel, so that the pixel dam forms a step structure, and an overflow solution can be in secondary contact with the step structure to form a ridge bridge, so that the solution is prevented from further overflowing; the color mixing risk is reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display terminal. Background technique [0002] Traditional OLED devices are produced by evaporation, but due to the high cost of materials, they are gradually replaced by inkjet printing. Inkjet printing mainly sprays the solution on the display area of ​​the display substrate, and then forms a thin film by evaporating the solvent. [0003] However, due to the limitations of printing accuracy and print head stability, some OLED devices are prone to color mixing due to liquid overflow during printing, resulting in abnormal display. Contents of the invention [0004] The present application provides a display panel and a display terminal to improve the technical problem that current OLED devices are prone to color mixing and cause abnormal display. [0005] In order to solve the above technical problems, the technical scheme provided by the appl...
