Embodiment Construction

[0049]In order to further illustrate the flexible display device provided by the embodiments of the present invention and the manufacturing method thereof, a detailed description will be given below in conjunction with the accompanying drawings.

[0050] see Figure 1a ~ Figure 1e , the manufacturing method of the flexible display device provided by the embodiment of the present invention includes:

[0051] Step 101, fabricate multiple flexible display devices on the carrier 3, and remove the film layer in the cutting area 1 between adjacent flexible display devices by using an etching process, exposing the carrier 3 in the cutting area 1, as Figure 1d shown;

[0052] Specifically, multiple display devices can be fabricated simultaneously on the glass carrier 3 in an arrangement with high utilization rate. During the process of manufacturing the display devices, the cutting area 1 between adjacent flexible display devices is cut The film layer is removed, so that the carrier...

Abstract

The invention discloses a flexible display device and a manufacturing method thereof, and relates to the field of display technology, in order to solve the problem that the existing cutting method for manufacturing a display device cannot realize the product design of an ultra-narrow frame while ensuring the quality of the device. The manufacturing method of the flexible display device includes: manufacturing a plurality of flexible display devices on a carrier board, and removing the film layer located in the cutting area between the adjacent flexible display devices by using an etching process, exposing the film layer located in the cutting area. The carrier plate in the area: the plurality of flexible display devices are peeled off from the carrier plate by using laser lift-off technology to form a plurality of independent flexible display devices. The manufacturing method of the flexible display device provided by the invention is used for manufacturing the flexible display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display device and a manufacturing method thereof. Background technique [0002] At present, in order to improve the production efficiency of the display device and reduce the production cost, whether the display device is a thin film transistor liquid crystal display (English: Thin Film Transistor Liquid Crystal Display, TFT-LCD for short), or an organic electroluminescent diode display device (English: : Organic Light Emitting Diode, referred to as: OLED), etc., are all processed on the motherboard and then cut and separated to further complete the back-end module process. [0003] Taking the production of a flexible display substrate including a flexible substrate as an example, a flexible substrate is first formed on a carrier plate, and then multiple display devices are simultaneously fabricated on the flexible substrate in a high-utility arrangement to form a fl...
