Problems solved by technology

During the coating process, the position of the substrate needs to be positioned first, and then the coating starts. Therefore, the positioning of the two half-panels and the state of the Sim will affect the positioning accuracy of the coating. However, in the actual manufacturing process, if the coating Problems with placement accuracy will lead to the scrapping of chips at the edge of the substrate

Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] refer to figure 1 and figure 2 , is the manufacturing method of the organic light-emitting display panel of the present invention, and the manufacturing method mainly includes:

[0032] S1. An array substrate 10 is provided, wherein the edges of the topmost metal layer of the array substrate 10 are etched to form a plurality of scale scales 100 respectively extending around. Each edge of the rectangular area in the middle of the array substrate 10 extends to form a scale scale 100, and the length direction of each scale scale 100 is respectively perpendicular to the corresponding side ...

Abstract

The present invention discloses an organic light -emitting display panel, including the array substrate and the organic light layer and the touch function layer with touch electrode patterns above the array substrate.A number of scales that are extended around each other, and the projection of the touch electrode pattern on the array of the array arrays is at least part of the scale.The present invention also revealed a method of making organic light -emitting display panels.In the light engraving process of the touch electrode pattern of the present invention, the coating process of the light resistance uses the scaled scale on the array substrate to monitor the position of the light resistance coating.The chip of the edge of the substrate caused by the light resistance is scrapped.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light-emitting display panel and a manufacturing method thereof. Background technique [0002] In the production process of Flexible AMOLED (flexible organic light-emitting diode) panels, in order to obtain a thinner substrate design, On-cell (referring to the color filter substrate and polarizer embedded in the touch screen into the display screen) is generally used. The method in between) the process in which the panel is directly made on the substrate. [0003] In the AMOLED process, the organic light-emitting material needs to be evaporated onto the Array (array) substrate through an evaporation machine. Due to the high price of the evaporation machine and the limitations of some characteristics of the equipment itself, it is impossible to produce a large-sized substrate. The existing production method is usually to cut the whole substrate in half after the Array...
