Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with examples, which are only preferred implementations of the present invention, and are not limitations of the present invention.

[0026] figure 1 It is a schematic side view of an existing flexible OLED display device using COG technology. Wherein, the printed circuit board 101 is attached to the display panel 102 , the two ends of the FPC103 are respectively connected to the printed circuit board 101 and the display panel 102 , and the FPC103 needs to be bent for connection, and the driving IC 104 is disposed on the display panel 102 . The components 105 for controlling the connection between the printed circuit board 101 and the display panel 102 and processing signals are welded on the FPC 103 , so that the FPC 103 needs to have a certain thickness and area to carry the components 105 . The display panel 102 includes an array substrate and a packaging substrate that are oppositely arranged. A...

Abstract

The invention discloses a flexible display device. The flexible display device comprises a display panel, a flexible circuit board, a driving IC and a printing circuit board, wherein the display panelis electrically connected with the printing circuit board through the flexible circuit board, the display panel is integrated with a first connecting circuit and a first component, the first connecting circuit is used for connecting the driving IC and the first component, and the first component is a component originally arranged on the flexible circuit board and used for controlling the connection between the printing circuit board and the display panel. The flexible display device has the advantages that some components and connecting circuits on a conventional flexible circuit board are integrated on an array substrate of the display panel, the load of the flexible circuit board is reduced, and only one layer of substrate is needed, so that compared with an existing flexible circuit board, the flexible display device is lighter and thinner, the thickness and weight of the display device are reduced, the risk of looseness of a sealant frame on the display panel in the flexible display device is greatly reduced, the risk of separation of the display panel is greatly reduced, and the service life of products is prolonged.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display device. Background technique [0002] Flexible display is an important development direction of display technology. This technology has the characteristics of being bendable, not fragile, ultra-light and ultra-thin, low power consumption, and portable. Application prospects and good development expectations. However, there are still many problems in flexible display technology, such as module assembly process. As we all know, the current panel industry generally uses COG or COF processes to assemble display panels, driver ICs, flexible circuit boards (FPC), and printed circuit boards (PCB). Both COG and COF processes use FPC to control the connection between the display panel and the circuit board, which requires the FPC to have a certain area and thickness to carry some electronic components that control the connection between the two, and for the COF proce...
