Description
Technical Field
The utility model relates to a display device, in particular to a flexible display screen.
Background
The conventional flexible display screen generally comprises a flexible substrate, an LED array arranged on the flexible substrate and a flexible protective layer arranged on the LED array, when the flexible display screen is bent, the surface of the flexible substrate and the flexible protective layer can generate large tension, and the LED is easy to loosen due to repeated bending.
SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned shortcomings, the present invention provides a flexible display screen, which has a small bending tension and can not cause the LED light emitting diode to loose after repeated bending.
In order to achieve the above purpose, the embodiment of the utility model adopts the following technical scheme:
a flexible display screen comprises a flexible transparent substrate and an LED array arranged on the flexible transparent substrate, wherein the LED array comprises a plurality of LED array units which are arranged in an array manner, and the LED array units comprise a plurality of LED light-emitting diodes; a groove is formed in the flexible transparent substrate at the junction of the adjacent LED array units; transparent protective films are arranged above the LED array units, and the transparent protective films above the adjacent LED array units are not connected with each other.
According to an aspect of the present invention, the material of the transparent protective film is selected from one of PET, PU and PDMS.
According to one aspect of the utility model, the LED light emitting diode is an OLED organic light emitting diode.
According to one aspect of the utility model, the flexible transparent substrate is connected with the LED through welding pads in a welding mode, and electrode wires for conducting the welding pads are arranged inside the flexible transparent substrate.
According to one aspect of the utility model, the flexible transparent substrate is made of one of PET, PU and PDMS.
The implementation of the utility model has the advantages that: the flexible display screen comprises a flexible transparent substrate and an LED array arranged on the flexible transparent substrate, wherein the LED array comprises a plurality of LED array units which are arranged in an array manner, and the LED array units comprise a plurality of LED light-emitting diodes; a groove is formed in the flexible transparent substrate at the junction of the adjacent LED array units; the transparent protective films are arranged above the LED array units, and the transparent protective films above the adjacent LED array units are not connected with each other, so that when the flexible display screen is bent, the flexible transparent substrate can generate larger deformation at the groove and smaller deformation at the position of the LED array units, and a large acting force cannot be generated between the LED lamp tube and the flexible transparent substrate; transparent protection film above adjacent LED array unit is not continuous for separate each other when buckling between the protection film, protection film itself can not be deformed hardly, just can not produce very big effort with between the LED lamp yet. Therefore, the LED lamp has the effects of small bending tension and no looseness of the LED caused by repeated bending.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic structural diagram of a flexible display screen according to the present invention;
fig. 2 is a schematic structural diagram of an LED array of a flexible display panel according to the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 and fig. 2, a flexible display screen includes a flexible transparent substrate 1 and an LED array disposed on the flexible transparent substrate, where the LED array includes a plurality of LED array units arranged in an array, and the LED array unit includes a plurality of LED light emitting diodes 2; a groove 3 is formed in the flexible transparent substrate at the junction of the adjacent LED array units; transparent protective films 4 are arranged above the LED array units, and the transparent protective films above the adjacent LED array units are not connected with each other. The protective film 4 is connected with the LED through an OCA optical adhesive layer 5.
In the present embodiment, each LED array unit includes 9 LED light emitting diodes arranged in a rectangular square matrix. The LED array units are arranged in a rectangular array. On the flexible transparent substrate, a plurality of grooves are longitudinally and transversely arranged and are arranged at the junction of the adjacent LED array units.
It should be noted that the LED array unit in this embodiment includes 9 LED light emitting diodes, and the number of the LED array units and the arrangement shape of the LED light emitting diodes in practical application depend on practical requirements.
The LED array units in this embodiment are arranged in a rectangular array, and in other embodiments, may take other forms of array arrangements.
The material of the transparent protective film is selected from one of PET (Polyethylene terephthalate), PU (Polyurethane) and PDMS (Polydimethylsiloxane). PET, PU and PDMS are all flexible transparent polymer materials. Theoretically, the transparent protective films are mutually separated, and have no mechanical action when the flexible display screen is bent, and the bending performance of the flexible display screen is not influenced because the transparent protective films are rigid films. However, in practical situations, the transparent protective film is easily collided together in consideration of repeated bending of the flexible display screen, and therefore, the material of the transparent protective film is preferably selected from flexible materials.
The LED is an OLED organic light emitting diode. After the flexible display screen is bent, the observation visual angle of a user can be in a wide range, the image quality of the traditional liquid crystal LED can be obviously reduced when the deviation of the observation visual angle is large, the display quality of the OLED is influenced by the observation visual angle to be small, and the OLED is more adaptive to the flexible display screen.
The flexible transparent substrate is connected with the LED through a bonding pad 6 in a welding mode, and an electrode wire 7 for conducting the bonding pad is arranged inside the flexible transparent substrate.
It should be noted that the specific arrangement of the electrode wires in fig. 1 is only a schematic diagram, and in practical application, the electrode wires include a positive electrode wire and a negative electrode wire, both of which are disposed inside the flexible transparent substrate and are communicated with the bonding pads. In practical application, the bonding pad is divided into two mutually insulated parts, and the anode and the cathode of the LED are respectively welded.
The flexible transparent substrate is made of one of PET, PU and PDMS.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention disclosed herein are intended to be covered by the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
