Problems solved by technology

[0004] However, there is a problem that there is no bending device for folding or rolling up the flexible display panel, which is the main structural element of the flexible display device according to the design.
[0005] In addition, there is a problem that when an operator manually performs such a display panel bending process, the operator cannot fold the display panel in an accurate shape according to the design value, and the production efficiency decreases due to a decrease in process efficiency.
[0006] Furthermore, there is a problem that the quality of the display panel is uneven depending on the operator's proficiency in the bending process.
[0007] That is, there is a problem that when the flexible substrate is bent manually, it is difficult to bend so that the curved portion of the flexible substrate has a desired radius of curvature.
In particular, there is a problem that excessive force is applied to the flexible substrate, causing physical and electrical damage to the flexible display

Abstract

The invention provides a display device and a bending device making same; the bending device can bend a part of the display device without damaging the display device, and uses a pedestal, a rack and a bending portion so as to bend partial the display device; the pedestal comprises a mounting surface used for configuring the display device; the rack comprises a clamp portion used for clamping a part, connected with the bended portion of the display device, of the display device; the bending portion is used for bending and pressurizing the bended portion.

Description

technical field [0001] The present invention relates to a bending device capable of bending a part of a display device for displaying images, and a display device manufactured by the device. Background technique [0002] Among display devices, attracting attention as next-generation display devices is a flexible display device that realizes pixels on a thin flexible substrate such as plastic and has the ability to be folded or rolled like paper. At the same time, the desired image can also be displayed. [0003] Flexible display devices are not only used in computer monitors and televisions, but are also widely used in personal portable devices. Accordingly, research into a flexible display device having a reduced volume and weight while having a wider display area is being conducted. Especially, since an organic light emitting display (Organic Light Emitting Display; OLED) does not require an additional light source unlike a liquid crystal display (Liquid Crystal Display;...
