Flexible display module and preparation method thereof

Abstract

The embodiment of the invention discloses a flexible display module and a preparation method thereof. The flexible display module comprises a flexible display screen, a driving chip and a circuit board, the flexible display screen comprises a display area and a bonding area, and the driving chip and the circuit board are respectively arranged on the bonding area; the circuit board comprises a first flexible circuit board and a first printed circuit board provided with an electronic device, the first printed circuit board is connected with one end of the first flexible circuit board, and the first flexible circuit board is provided with a bonding part in bonding connection with the bonding area of the flexible display screen; the first printed circuit board is bent through the first flexible circuit board, so that the first flexible circuit board, the first printed circuit board and the flexible display screen form a first space, and the electronic device is located in the first space. According to the flexible display module, the space ratio of the circuit board can be effectively reduced, so that the available space of the whole device of the flexible display module is increased, the overall performance of the flexible display device is improved, and the product competitiveness is improved.

Description

technical field [0001] The present application relates to the field of display technology. More specifically, it relates to a flexible display module and a preparation method thereof. Background technique [0002] With the increasing development of display technology, various new technologies are emerging, among which, with the development of flexible display technology, flexible display screens emerge as the times require. The advent of flexible screens has met people's new demands for displays. At present, flexible displays have been widely used in smart wearables and smartphones. Consumers are interested in flexible display electronics with smaller size, narrower frame and better performance. There is a strong demand for the product. [0003] The circuit board in the flexible screen electronic product is an important part for the flexible screen to be lit and driven and controlled, and it is an important information transmission channel connecting the whole machine stru...

Problems solved by technology

The circuit boards used in smart wearables and smart phones in the prior art all use flexible printed circuit boards (Flexible Printed Circuit, FPC). The flexible display module structure 100 in the prior art is as follows: Figure 1-3 As shown, it includes a cover plate 110, a flexible display 120, a flexible circuit board 130 and a driver chip 140 located on the back of the flexible display 120. The flexible circuit board 130 occupies a large space, and the upper surface of the flexible circuit board 130 is provided with The capacitive inductive device 150, so that when the structural devices required for the overall structure are arranged above the flexible circuit board 130, there are relatively large limitations: first, the capacitive inductive device 150 located on the upper surface of the flexible circuit board 130 is easy to be located on the capacitive inductive device 150. The structure of the whole machine above the inductance device 150 interferes and collides, causing the capacitive inductance device 150 to be damaged; at the same time, the occupied space of the flexible circuit board 130 is large, thereby reducing the utilization space of the whole machine device (such as figure 1 The slashed area shown in the figure), it will cause great difficulty in the assembly and placement of the whole device (such as battery and motherboard), reduce the overall performance of the flexible display module, and reduce the acceptance of consumers
