OLED display device

Abstract

The invention provides an OLED display device, comprising a flexible substrate, wherein the flexible substrate comprises a display region and a non-display region located at one end of the display region; A TFT layer and an OLED light emitting lay are arranged on the flexible substrate, and a part of the TFT layer located in the non-display region is provided with at least two grooves; An encapsulating film layer including a first inorganic layer, an organic layer, and a second inorganic layer which are overlapped, the first inorganic layer and the second inorganic layer extending from the display region to a non-display region, and the first inorganic layer and the second inorganic layer cover the trench.: An OLED display device according to the present invention has beneficial effects that At least two grooves are etched on the TFT layer in the non-display region, which makes water and oxygen permeation more difficult, thereby enhancing the ability of the encapsulation film layer toisolate water and oxygen, reducing the risk of the devices inside the OLED display device being oxidized, and at the same time, relieving the substrate crack propagation stress.

Description

technical field [0001] The invention relates to the technical field of display driving, in particular to an OLED display device. Background technique [0002] At present, organic light-emitting diode (OLED) devices are considered to be ideal substitutes for traditional LCDs because of their advantages such as self-illumination, high color reproduction, flexibility and bendability. However, OLED devices are sensitive to water and oxygen, and the penetration of water and oxygen has a great impact on the life of the device, so strict packaging is required. At present, thin film packaging is mainly used in the industry. [0003] Thin-film packaging generally has a sandwich structure. Two inorganic layers function to isolate water and oxygen, and an organic layer is sandwiched in the middle to function as a flat buffer. If the interface contact between the two inorganic layers in the non-display area and the driving layer is not good, water and oxygen will easily infiltrate alo...

AI Technical Summary

Problems solved by technology

[0005] The invention provides an OLED display device, which can protect the OLED device from oxidation caused by water vapor corrosion, so as to solve the problem of the existing OLED display device, due to poor interface contact between the two inorganic layers of the non-display area packaging layer and the TFT drive layer or the TFT There are cracks on the surface of the driving layer, and water and oxygen can easily penetrate into the OLED device, causing the OLED device to be oxidized and resulting in a technical problem such as a decrease in the life of the OLED device.
