This application claims priority to and benefits of Chinese Patent Application No. 201710342858.X, filed with State Intellectual Property Office on May 12, 2017, the entire content of which is incorporated herein by reference.
The present disclosure relates to a technical field of electronic equipment, and more particularly to a splicing screen, a display device and a mobile terminal.
A flexible screen is obviously superior to a screen, not only in lighter and thinner dimension, but also in lower consumption than an original component, which is conductive to improving endurance of a device. Meanwhile, the flexible screen has much higher durability than previous screens due to its characteristics of bendability and good flexibility, and the probability of accidental damage to the device is reduced.
The present disclosure provides a splicing screen, including: a flexible screen, an LED screen and a flexible circuit board. The flexible screen has an opening running through the flexible screen, and the LED screen is arranged in the opening. A signal line in the LED screen is bonded to the flexible circuit board, and a signal line in the flexible circuit board is bonded to the flexible screen.
The present disclosure further provides a display device. The display device includes a fingerprint identification module and a splicing screen. The splicing screen includes an organic light-emitting diode screen having an opening running through the organic light-emitting diode screen; a light emitting diode screen provided in the opening; a flexible circuit board, a signal line in the light emitting diode screen being bonded to a flexible circuit board, and a signal line in the flexible circuit board being bonded to the organic light-emitting diode screen. The fingerprint identification module is provided on the light emitting diode screen.
The present disclosure further provides a mobile terminal. The mobile terminal includes a display device including a fingerprint identification module and a splicing screen. The splicing screen includes: a flexible screen having an opening running through the flexible screen; an LED screen provided in the opening; a flexible circuit board capable of transferring signal, and a signal line of the LED screen being bonded to the flexible screen through relay of the signal line of the LED screen. The fingerprint identification module is provided on the LED screen.

Referring to
The splicing screen 1 is bendable, and the position of the hard screen 12 enhances rigidity of the splicing screen 1 to a certain extent, such that it is convenient to apply the splicing screen 1 to various devices and mount various components (like the fingerprint identification module) to the splicing screen, thereby improving the reliability of the splicing screen 1. The display device 10 and the mobile terminal 100 adopt the above splicing screen 1, and since the splicing screen 1 is provided with the hard screen 12, the fingerprint identification module can be mounted to the hard screen 12 well, improving the reliability of the display device 10 and the mobile terminal 100.
It could be understood that, referring to
It could be understood that the opening 11c is processed out of the flexible screen 11 by laser cutting. Certainly, in other embodiments, the opening 11c can be processed out of the flexible screen 11 in other manners, for example, through a numerically-controlled machine tool.
The hard screen 12 is a light-emitting diode (LED) screen. The hard screen 12 has a second front surface 12a and a second rear surface 12b arranged opposite to each other; the second front surface 12a is a surface that faces the user and can perform touch and display operations, while the second rear surface 12b is generally located in the interior of the mobile terminal 100. The hard screen 12 is substantially consistent with the opening 11c in terms of size and shape, so the hard screen 12 can be provided in the opening 11c well to ensure the integrity of the splicing screen 1.
Specifically, the flexible screen 11 is electrically coupled with the hard screen 12 in such a way that the signal line in the hard screen 12, i.e. a thin film transistor (TFT) circuit in the hard screen 12, is hot-pressed to the flexible circuit board 13 through a FOG (Flex On Glass FPC) technology, and the signal line is hot-pressed by the flexible circuit board 13 to a TFT circuit of the flexible screen 11 through the FOG technology, such that the hard screen 12 is electrically coupled with the flexible screen 11. The flexible circuit board 13 plays a role of signal transfer, and the signal line in the hard screen 12 is bonded to the flexible screen 11 through the relay of the signal line in the hard screen 12, so as to achieve the electrical coupling between the hard screen 12 and the flexible screen 11. After the flexible circuit board 13 is re-coupled to a motherboard of the mobile terminal 100, the motherboard can control the display of the flexible screen 11 and the hard screen 12.
The first front surface 11a of the flexible screen 11 and the second front surface 12a of the hard screen 12 are flush and spliced into a first surface of the splicing screen 1. The first rear surface 11b of the flexible screen 11 and the second rear surface 12b of the hard screen 12 are spliced into a second surface of the splicing screen 1.
It could be understood that a size of the flexible screen 11 is much larger than a size of the hard screen 12, i.e. the splicing screen 1 is mainly composed of the flexible screen 11, so as to ensure relatively small thickness and good bendability of the splicing screen 1.
It could be understood that the flexible screen 11 has the display area D1 for image display, and the opening 11c is located in the display area D1. By providing the opening 11c in the display area D1 of the display screen, the strength of the position where the opening 11c is provided in the display area D1 is enhanced. Certainly, in other embodiments, the flexible screen 11 can be located in the non-display area D2 of the flexible screen 11.
It could be understood that, referring to
Further, referring to
It could be understood that the size of the hard screen 12 is the same as that of the fingerprint identification module 2, so as to further reduce the proportion of the hard screen 12 in the splicing screen 1 and ensure good bendability of the splicing screen 1.
It could be understood that the fingerprint identification module 2 is an optical fingerprint identification component. Certainly, in other embodiments, the fingerprint identification module 2 can be an infrared fingerprint identification component.
During manufacturing of the mobile terminal 100, the hard screen 12 is first provided in the opening 11c of the flexible screen 11, and then the fingerprint identification module 2 is hot-pressed to the second rear surface 12b of the hard screen 12, so that the fingerprint identification module 2 is accommodated in the mobile terminal 100. The user can perform a fingerprint identification operation by pressing the hard screen 12, and the hard screen 12 can display together with the flexible screen 11 when no fingerprint identification operation is performed.
For the splicing screen 1 according to the present disclosure, by providing the hard screen 12 in the opening 11c of the flexible screen 11, and splicing the flexible screen 11 and the hard screen 12 into the splicing screen 1, this splicing screen 1 is bendable, and the position of the hard screen 12 enhances the rigidity of the splicing screen 1 to a certain extent, such that it is convenient to apply the splicing screen 1 to various devices and mount various components (like the fingerprint identification module) to the splicing screen, thereby improving the reliability of the splicing screen 1.
The display device 10, 20, 30 and the mobile terminal 100 according to the present disclosure adopt the above splicing screen 1, and since the splicing screen 1 is provided with the hard screen 12, the fingerprint identification module can be attached to the hard screen 12 well, improving the reliability of the display device 10 and the mobile terminal 100.
The above are preferred embodiments of the present disclosure, and it should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present disclosure, and these improvements and modifications are also regarded as the protection scope of the present disclosure.
