Embodiment Construction

[0028] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar elements are denoted by the same reference numerals. In the drawings, the thicknesses of some layers and regions are exaggerated for clear understanding and ease of description. That is, the size and thickness of each component shown in the drawings are arbitrarily shown, but the present invention is not limited thereto.

[0029] In one example, see figure 1 , figure 1 A schematic top view structure diagram of a display...

Abstract

The invention provides a display panel and a production method thereof, and a display device. A plurality of first electrodes are arranged on an array substrate of the display panel, a first interval and a second interval are arranged between the first electrodes, each first pixel separation levee is arranged corresponding to the first interval, and each second pixel separation levee is arranged corresponding to the second interval; each second pixel separation levee crosses the first pixel separation levee, the thicknesses of the first pixel separation levee and the second pixel separation levee are both larger than the thickness of the first electrodes, and the thickness of the second pixel separation levee is larger than the thickness of the first pixel separation levee so that light-emitting materials of the same color can be continuously printed between the adjacent second pixel separation levees; and the problem that the printing efficiency is affected due to the fact that an existing SBS type pixel definition layer cannot be continuously printed is solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Compared with liquid crystal display (Liquid Crystal Display, LCD), active matrix organic light emitting diode display (Active Matrix Organic Light Emitting Display, AMOLED) has the advantages of high color gamut, high contrast, flexibility and wearable. According to the OLED preparation process, the preparation of AMOLED can be divided into evaporation type and ink jet printing (Ink jet Print, IJP) type. For the production of large-size display backplanes, the evaporation technology needs to rely on white OLED (WOLED) combined with color filters (Color Filter, CF) to achieve color display, while the CF-free display corresponding to fine masks cannot be applied to large-scale display. Mass production of high-size high-generation lines. The inkjet printing process overcomes the ...
