Cutting method and cutting tool of glass substrate of flexible organic light-emitting diode display

Abstract

The invention discloses a cutting method and a cutting tool of a glass substrate of a flexible organic light-emitting diode display. The cutting tool comprises a pair of blade knives, a scraper knife and a cutter wheel. The scraper knife is positioned between the blade knives and the cutter wheel. The method comprises the following steps: the cutting tool is positioned above a flexible material; along a cutting direction, the pair of blade knives arranged side by side are positioned on the front, wherein the blades of the blade knives have acute angles; the cutting tools are started, and the two blade knives cut the flexible material along the cutting direction from one end of the flexible material; the scraper knife arranged behind the blade knives peels the cut flexible material between the two blade knives from the glass substrate; with the action of the scraper knife, a gap with width equal to the spacing between the two blade knives is cut on the flexible material; the cutter wheel behind the scraper knife performs a scoring process on the glass substrate exposed after the peeling of the flexible material; and a splitting process is carried out, such that the glass substrate is completely separated. According to the invention, the cutting of the flexible material and the glass substrate is completed in one step with the combined cutting tool and necessary accessories.

Description

technical field [0001] The present invention relates to a glass substrate cutting method and a cutting tool, in particular to a method for cutting a flexible organic light emitting display (OLED, Organic Light Emitting Diode) glass / organic film composite substrate covered with a flexible material and the method for realizing the method cutting knives. Background technique [0002] Organic light-emitting display device (OLED) is an active light-emitting device. Compared with the current mainstream flat-panel display technology thin-film transistor liquid crystal display (TFT-LCD), OLED has the advantages of high contrast, wide viewing angle, low power consumption, and thinner volume. It is expected to become The next-generation flat-panel display technology after LCD is one of the most concerned technologies in flat-panel display technology. [0003] In particular, active matrix organic light emitting display (AMOLED, Active Matrix Organic Light Emitting Diode) has the adva...

AI Technical Summary

Problems solved by technology

Therefore, the edge of the cutter wheel is usually obtuse (such as figure 1 shown in the middle angle), but in the case of cutting covered flexible material substrates, this blade cannot effectively cut the flexible material, that is, it cannot form a score on the glass substrate

Even if a score is cut from one side of the back glass substrate (such as figure 1 and figure 2 shown), in the process of splitting, due to the adhesion of flexible materials, it cannot be separated normally
