Problems solved by technology

[0003] An embodiment of the present invention provides an OLED display device, which is used to solve the problem that the arc deformation of the bending area is too large due to the dislocation of the film layer during the dynamic bending of the OLED display device in the prior art, which causes the film layer in the bending area to break and fail. Technical issues causing display exceptions

Abstract

The invention provides an OLED display device. The OLED display device comprises an OLED display panel, a supporting assembly and a cover plate, the OLED display panel comprises a first plane area, a second plane area and a bending area connected with the first plane area and the second plane area, and the bending area comprises an arc-shaped area and a sliding transition area; wherein a supporting plate is arranged on the side, away from the supporting assembly, of the OLED display panel in the second plane area, and the supporting plate and the cover plate act together so that the sliding transition area can be coplanar with the first plane area and/or the second plane area. When the OLED display device is dynamically bent to cause dislocation of a film layer, the arc-shaped area can synchronously slide along with the film layer due to the traction force effect of dislocation, the sliding transition area can synchronously slide and roll along with the film layer due to the bending performance, the curvature of the arc-shaped area is limited through the combined action of the supporting plate and the cover plate, the bending form of the arc-shaped area can be kept, and the situation of poor display caused by film layer fracture due to excessive deformation of the arc-shaped area is avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display device. Background technique [0002] Compared with LCD (Liquid Crystal Display, Liquid Crystal Display) technology, OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display technology has the biggest advantage of being flexible and foldable. At present, pad bending (panel bending) technology is widely used in OLED display panel narrow frame technology, and the bending radius of the bending area of ​​pad bending is about 0.25-0.5 mm. However, at present, when flexible OLED display devices are dynamically bent, especially for outward-curved products and cloud roll screens, the misalignment of the film layer will drive the arc deformation of the bending area. When the arc is pulled too large, it is easy to cause the bending area to deform. The display is abnormal due to the rupture of the film layer. Therefore, it is necessary to improve this def...
