Problems solved by technology

[0003] For the current flexible OLED screen bending fixture, because the thickness of different flexible OLED screens is different, and the bending angle and bending radius required by different flexible OLED screens are also different, in order to be compatible with different thicknesses, bending radii and bending The flexible OLED screen with a bending angle can be bent. Most of the bending fixtures do not sufficiently restrict the flexible OLED screen during the bending process, resulting in some areas of the flexible OLED screen after bending, especially at the junction of the bend. The phenomenon of uneven coverage greatly affects the bending quality and yield of flexible OLED screens

Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] see figure 1 The bending jig 100 includes a bracket 10, a die 20, a punch 30 and a pressure handle 40, the bracket 10 cooperates with the die 20, the punch 30 cooperates with the pressure handle 40, and the flexible OLED The screen 200 is bent and shaped through the cooperation and pressing of the concave mold 20 and the convex mold 30 . Wherein, the bracket 10 includes a base 11, a left side plate 12 and a right side plate 13, and the ba...

Abstract

The invention relates to the field of display screen manufacturing, and discloses a bending fixture of a flexible OLED screen. The bending fixture comprises a bracket, concave dies, convex dies and apressing handle, and the bracket and the pressing handle are used for fixing the concave dies and the convex dies respectively so that the concave dies and the convex dies can be fitted to press the flexible OLED screen. Since grooves in the concave dies and protrusions on the convex dies are arranged opposite to each other, and particularly in an arrangement mode of linear sections every two of which are matched with each other, a bent area, a non-bent area and an overlapping area of the bent area and the non-bent area of the flexible OLED screen can be tightly supported in the bending process. While the bending operation is completed accurately, the fitting consistency of the flexible OLED screen is ensured, the bending quality of the bending process is improved, and the qualified product rate is increased.

Description

technical field [0001] The invention relates to the field of display screen manufacturing, in particular to a bending process of a flexible OLED screen. Background technique [0002] Flexible OLED screens are widely used due to their features such as no need for backlights, large viewing angles, and light and thin power. In particular, their flexibility allows the screen to be bent, and its plasticity is much higher than that of LCD and other previous-generation display products. . [0003] For the current flexible OLED screen bending fixture, because the thickness of different flexible OLED screens is different, and the bending angle and bending radius required by different flexible OLED screens are also different, in order to be compatible with different thicknesses, bending radii and bending The flexible OLED screen with a bending angle can be bent. Most of the bending fixtures do not sufficiently restrict the flexible OLED screen during the bending process, resulting in...
