Problems solved by technology

[0004] Further, after cutting the combination of the thin film transistor array substrate 101 and the cover plate 102, due to the warping of the thin film transistor array substrate 101 or the cover plate 102, the thin film transistor array substrate 101 and the cover plate 102 cannot be fastened, so any one of them Or easily displaced, so that the combination of the thin film transistor array substrate 101 and the cover plate 102 has a low structural strength. When the middle of the cover plate 102 is pressed, the sintered glue located at the edges of the thin film transistor array substrate 101 and the cover plate 102 tends to act as a fulcrum, and the edge of the thin film transistor array substrate 101 or the edge of the cover plate 102 will revolve around this fulcrum. Warpage, which makes the structure of the OLED display panel unstable, and affects the quality of the finished OLED display panel

Abstract

The invention discloses an organic light-emitting diode display panel, which comprises a first thin film transistor array substrate; a first cover plate is arranged on the first thin film transistor array substrate, wherein the first cover plate is provided with first sintering glue and second sintering glue, and an area between the first and the second glue corresponds to the first thin film transistor array substrate; and structural strengthening glue arranged outside the first and the second glue of the first cover plate and contacted with the first thin film transistor array substrate and the first cover plate. The invention further discloses a manufacturing method of the organic light-emitting diode display panel. The invention prevents the phenomenon that the thin film transistor array substrate or the cover plate warps caused by a negative pressure between the thin film transistor array substrate and the cover plate, so that the organic light-emitting diode display panel is more firm and stable in structure.

Description

【Technical Field】 [0001] The present invention relates to the field of organic light emitting diode display technology, in particular to an organic light emitting diode display panel and a manufacturing method thereof. 【Background technique】 [0002] In the manufacturing process of the traditional organic light-emitting diode display panel, a sintering (Frit) glue (1031, 1032, 1033 and 1034) needs to be arranged between the thin film transistor array substrate 101 and the cover plate 102, and the sintering glue is arranged on the thin film transistor array. The edge of the sub-substrates of the substrate 101 (the first thin film transistor array substrate 1011 and the second thin film transistor array substrate 1012), and then the thin film transistor array substrate 101 and the cover plate 102 (the first cover plate 1021 and the second cover plate 1022) The pairing is performed, and then the combination of the thin film transistor array substrate 101 and the cover plate 102 is c...
