Embodiment Construction

[0036] After long-term research, the inventor believes that the flexible display device in the prior art is prone to circuit breakage, mainly because the strain generated by the long line accumulates through the distance, which will cause a large stress in a certain position, thereby forming cracks. Therefore, the inventor changed the circuit into a combination of multiple small sections, that is, at least two layers of metal layers and plugs are used to make the required circuit. In this broken line, the total deformation within a certain distance can be divided into several parts. On a small line segment, the strain accumulation over a longer distance is eliminated and the risk of cracking is reduced.

[0037] The preferred embodiments of the flexible display device are listed below to clearly illustrate the content of the present invention. It should be clear that the content of the present invention is not limited to the following embodiments, and other conventional technic...

Abstract

The invention discloses a flexible displaying device which comprises a plurality of gate lines and a plurality of data lines crossed with the gate lines. The gate lines comprise gate line first parts and gate line second parts placed in at least an upper metal layer and a lower metal layer respectively. The gate line first parts and the gate line second parts are electrically connected through plugs. The data lines comprise data line first parts and data line second parts placed in at least an upper metal layer and a lower metal layer respectively. The data line first parts and the data line second parts are electrically connected through plugs. The invention further provides a manufacturing method of the flexible displaying device. According to the flexible displaying device, a line is made into a plurality of small sections, a broken line shape is formed, stress accumulation is effectively removed, and line breaking is avoided.

Description

technical field [0001] The invention relates to the display field, in particular to a flexible display device and a manufacturing method thereof. Background technique [0002] Among light-emitting type flat panel display devices, organic light-emitting display devices have excellent characteristics such as wide viewing angle, high contrast ratio, and short response time. Therefore, organic light-emitting display devices are widely used in products such as digital cameras, video cameras, notebook computers, tablets, and mobile phones. [0003] With the further development of display devices and consumers' increasingly demanding experience, flexible display devices emerge as the times require. An important indicator of a flexible display device is the degree of bendability (folding). At present, this factor has been restricting the development of flexible display technology. Such as figure 1 As shown, the film layer circuit layout of the conventional conventional flexible ...
