Display device and preparation method thereof

Abstract

Embodiments of the invention disclose a display device and a preparation method thereof. The display device comprises a screen body and a first supporting layer, wherein the screen body comprises a display area and a non-display area outside the display area; the non-display area comprises a bent part and a bent extension part; the first support layer is located above the display area and is located between the display area and the bent extension part; the first supporting layer is provided with a first part overlapped with the display area and a part of the non-display area and a second partoverlapped with the bent part; and the second part is bent or a part is cut off from the side, close to the bent part, of the second part. The first supporting layer is improved, so that interferencebetween the screen body and the edge of the first supporting layerduring bending of the screen body is avoided, the stress concentration is relieved, the open circuit risk of the screen body is lowered, and the display effect of the screen body is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display device and a preparation method thereof. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode), as a current-type light-emitting device, is widely used in the field of high-performance display due to its characteristics of self-luminescence, fast response, wide viewing angle and can be fabricated on flexible substrates. middle. At present, achieving a "true full screen" is one of the important goals of various mobile phone manufacturers (narrower borders, especially the lower border), and OLED flexible screens are considered to be the best solution to achieve "true full screen". However, at present, the flexible screen is prone to stress concentration during bending, and the organic layer is easy to fall off, resulting in abnormal display. How to prevent the open circuit when the flexible screen body is bent is th...

At present, achieving "true full screen" is one of the important goals of various mobile phone manufacturers (narrower borders, especially the lower bezel), and OLED flexible screens are considered to be the best solution to achieve "true full screen". However, at present, flexible screens are prone to stress concentration when they are bent, and the organic layer is easy to fall off, resulting in abnormal display. How to prevent circuit breakage when the flexible screen is bent is the key technical challenge for the development of full screens at present.
