Referring to fig. 1, a flexible display panel 100 according to an embodiment of the present invention includes a display area 10, a lead area 20, and a driving chip 30.
The display area 10 is provided with a through hole 11, and the display area 10 defines a first bending axis 12 and a second bending axis 13. The first bending axis 12 and the second bending axis 13 both cross the through hole 11 and intersect with the through hole 11; the flexible display 100 is capable of being bent along a first bending axis 12 and a second bending axis 13. Thus, the first bending axis 12 and the second bending axis 13 can divide the display area 10 into four regions, so that the flexible display screen 100 can be folded into a smaller size, and the space occupied by the flexible display screen 100 is reduced.
The lead area 20 is provided with a plurality of leads 21, and the leads 21 are connected to the display area 10. The driving chip 30 is electrically connected to the leads 21. The driving chip 30 is disposed outside the first bending axis 12 and the second bending axis 13.
In the flexible display screen 100, the driving chip 30 is disposed outside the first bending axis 12 and the second bending axis 13, so that interference between the flexible display screen 100 and the driving chip 30 during bending is avoided, and damage to the driving chip 30 during bending of the flexible display screen 100 is avoided.
Specifically, the display area 10 can display text, images and other contents, and since the display area 10 is provided with the through hole 11, the display contents of the display area 10 are partitioned at the through hole 11. The through-hole 11 may be used to mount an operating element or the like to control the operating state of the flexible display screen 100. For example, the operation element is a button, and the button can control the flexible display 100 to be turned on or off. When the flexible display screen 100 is used, the operating elements are mounted in the through holes 11. When the flexible display 100 is not used, the operating elements in the through holes 11 may be detached so that the flexible display 100 may be bent. The flexible display screen 100 can be firstly bent along the first bending axis 12 for the first time, and then bent along the second bending axis 13 for the second time, so that the flexible display screen 100 can be folded for four times, the occupied space of the flexible display screen 100 is reduced, and the flexible display screen 100 is convenient to store. Of course, the flexible display panel 100 can be bent along the first bending axis 12 only, or along the second bending axis 13.
In the present embodiment, the through-hole 11 is a circular through-hole. In other embodiments, the through hole 11 may be a square, rectangular, hexagonal, fan-shaped, or other through hole.
Preferably, the through hole 11 is located at the center of the display area 10. For example, when the outer shape of the display area 10 is a rectangle, the through-hole 11 is located at an intersection position of diagonal lines of the display area 10.
It is to be understood that a plurality of display circuits 14 are provided in the display area 10, and the display circuits 14 are formed with, for example, display pixels that can allow the display area 10 to display contents when the display circuits 14 are operated. As shown in fig. 1, a dotted line with an arrow in fig. 1 represents the display circuit 14 in the display area 10, wherein an indication direction of the arrow of the dotted line may represent a transmission direction of a signal. Each display circuit 14 is electrically connected to a lead 10.
The lead lines 21 may be connected with an external element so that the display region 10 may operate normally. For example, the lead line 21 is connected to an external power source, which can supply power to the display area 10. It should be noted that the lead pad 20 has flexibility, and can be bent.
The driving chip 30 is, for example, a Source Driver chip 30(Source Driver), and the driving chip 30 may provide a Source Signal (Source Signal) for the display area 10 to drive the display area 10 to display text, images, and the like.
The first bending axis 12 and the second bending axis 13 intersect, and it is understood that the first bending axis 12 and the second bending axis 13 intersect in the same plane, or the first bending axis 12 and the second bending axis 13 intersect stereoscopically.
In some embodiments, the display area 10 includes a first edge 15 and a second edge 16. The second edge 16 is perpendicularly connected to the first edge 15. The first bending axis 12 intersects the first edge 15, the second bending axis 13 intersects the second edge 16, and the lead 21 is electrically connected to the display circuit 14 at the location of the first edge 15.
In this way, the display area 10 has a rectangular shape, and the rectangular display area 10 is easy to manufacture and mold, and conforms to the habit of the user to watch the displayed information by using the flexible display screen 100, so that the user experience can be improved.
In the present embodiment, the display area 10 has a rectangular shape, the first edge 15 is a short edge of the display area 10, and the second edge 16 is a long edge of the display area 10. Of course, in other embodiments, the display area 10 may be square, with the length of the first edge 15 being equal to the length of the second edge 16.
In some embodiments, the display area 10 includes two first edges 15 that are parallel to each other. The leads 21 on the lead pads 20 are electrically connected to the display circuit 40 at each first edge 15 location, and at least one driver chip 30 is connected to the leads 21 of each lead pad 20. The display area 10 includes at least two sub-display areas 19, each driving chip 30 individually drives one sub-display area 19 to operate, and all the driving chips 30 cooperatively drive the display area 10 to operate.
In the example of fig. 1, one driver chip 30 is connected to the lead 21 on the lead pad 20 at the position of the upper first edge 15, and one driver chip 30 is connected to the lead 21 on the lead pad 20 at the position of the lower first edge 15. The upper driver chip 30 is located at the left outer side of the first bending axis 12, and the lower driver chip 30 is located at the right outer side of the first bending axis 12.
Of course, in other embodiments, the number and the positions of the upper driving chips 30 and the number and the positions of the lower driving chips 30 may have different embodiments.
For example, the upper single driver chip 30 and the lower single driver chip 30 may be located at the left outer side or the right outer side of the first bending axis 12 at the same time; for another example, the upper single driver chip 30 is located at the right outer side of the first bending axis 12, and the lower single driver chip 30 is located at the left outer side of the first bending axis 12; for another example, two driver chips 30 are connected to the lead 21 of the upper first edge 15, one driver chip 30 is connected to the lead 21 of the lower first edge 15, the two upper driver chips 30 are located on both outer sides of the first bending axis 12, and the lower driver chip 30 is located on the left outer side or the right outer side of the first bending axis 12.
As shown in fig. 1, when the single driving chip 30 is connected to the lead 21 at the upper first edge 15 and the single driving chip 30 is connected to the lead 21 at the lower first edge 15, the through hole 11 cannot display, so that the upper driving chip 30 can drive the left sub-display area 19 (e.g., area a) of the display area 10 to operate, and the lower driving chip 30 can drive the right sub-display area 19 (e.g., area B) of the display area 10 to operate, so that part of the sub-display areas 19 of the display area 10 can operate independently to display contents.
Of course, when the driving chip 30 connected to the lead 21 at the upper first edge 15 and the driving chip 30 connected to the lead 21 at the lower first edge 15 drive the left sub-display section 19 and the right sub-display section 19 of the lower display section 10 to operate simultaneously, all the sub-display sections 19 of the display section 10 may operate together, and all the sub-display sections 19 are used for displaying information contents.
Referring to fig. 2, the upper driving chip 30 can drive the upper sub-display area 19 (e.g., area C) of the display area 10 to work, and the lower driving chip 30 can drive the lower sub-display area 19 (e.g., area D) of the display area 10 to work, so that all the sub-display areas 19 of the display area 10 can work completely, thereby displaying the content.
It is understood that when a plurality of driving chips 30 are connected to the leads 21 at the position of each first edge 15, each driving chip 30 can respectively drive different sub-display regions of the display region 10 to operate. For example, the first bending axis 12 and the second bending axis 13 may divide the display area 10 into four sub-display areas, i.e., an upper left sub-display area, an upper right sub-display area, a lower left sub-display area, and a lower right sub-display area. When two driving chips 30 are connected to the lead 21 at each first edge 15, one driving chip 30 located above may drive the upper left sub-display region of the display region 10 to operate, and the other driving chip 30 located above may drive the upper right sub-display region of the display region 10 to operate. One of the driving chips 30 located below may drive the lower left sub-display area of the display area 10 to operate, and the other driving chip 30 located below may drive the lower right sub-display area of the display area 10 to operate.
In some embodiments, at least one sub-display 19 of the at least two sub-display sections 19 of the display section 11 encloses the through-hole 11.
As shown in fig. 1 and 2, there are two sub-display regions 19, and the two sub-display regions 19 surround the through hole 11. Alternatively, the a and B regions may define the via 11 or the C and D regions may define the via 11.
In the example of fig. 8, three sub-display sections 19 of the display section 10 are provided, i.e., an E region, an F region, and a G region. Wherein the region F and the region G enclose the through hole 11.
In some embodiments, the lead 21 is connected to only one driving chip 30, the display circuits 14 are disposed around the through holes 11 at the positions of the through holes 11, and the driving chips 30 drive all the display circuits 14 of the display screen 100.
In one example, as shown in fig. 3, a single driving chip 30 is connected to the lead 21 at one first edge 15, and the single driving chip 30 drives the whole display area 10 to work. Since the through hole 11 cannot be provided with the circuit 14, part of the display circuit 14 is disposed around the through hole 11, and the driving chip 30 drives the entire display circuit 14 to operate the display region 10.
Alternatively, the display circuit 14 around the through hole 11 surrounds the through hole 11 in a curved or broken line manner, so that the area around the through hole 11 can display the content. When only a single driving chip 30 is disposed in the flexible display 100, the number of components of the flexible display 100 can be reduced, thereby reducing the cost of the flexible display 100.
Referring to fig. 5, the lead 21 connects the two driving chips 30, the display circuit 14 is disposed around the through hole 11 at the position of the through hole 11, and each driving chip 30 is respectively located at one side of the first bending axis 12 and respectively drives the display circuit 14 located at one side of the first bending axis 12.
Referring to fig. 5-7, in some embodiments, the lead 21 includes two bending portions 22 in a bending shape, the bending portions 22 are tapered along a bending direction R of the bending portions 22, each bending portion 22 is connected to a single driving chip 30, and the first bending axis 12 is located between the two bending portions 22.
So, the portion of bending 22 that is the form of bending can reduce the frame of flexible display screen 100 to, the portion of bending 22 is the convergent shape and makes flexible display screen 100 bend along first axis of bending 12, thereby makes flexible display screen 100 can compromise the narrow frame simultaneously and show and have the bending nature.
Specifically, in the direction in which the bent portion 22 is bent, the plurality of leads 21 are gathered so that the arrangement shape of the leads 21 matches the bent portion 22. It will be appreciated that the display area 10 includes a display surface 17 and a back surface 18. The display surface 17 and the back surface 18 are disposed opposite each other. The display surface 17 is used for displaying information such as characters and images.
In one example, when manufacturing the flexible display screen 100, a whole display screen may be cut to form the display area 10 and the lead area 20, and the bending portion 22 is made to be a tapered shape along the direction of the first edge 15 away from the display area 10 when being tiled, then the lead 21 gathered together is formed on the lead area 20, and finally the bending portion 22 with the lead 21 is bent to the back 18 of the display area 10, so that the ratio of the area of the display area 10 to the front profile area of the flexible display screen 100 may be made larger, and the flexible display screen 100 may have a narrow-frame display.
Referring to fig. 1 again, in some embodiments, the display region 10 includes two second edges 16 parallel to each other, and each second edge 16 is connected to a first gate driving circuit 40.
In this way, the first Gate driving circuit 40 may provide a Gate Signal (Gate Signal) to the display area 10 to drive the display area 10 to display contents. The first gate driving circuit 40 may drive the display region 10 to operate together with the driving chip 30. It should be noted that the first gate driving circuit 40 has certain flexibility, so that when the flexible display panel 100 is bent, the first gate driving circuit 40 can also be bent without being damaged.
In some embodiments, a second gate driving circuit 50 is connected to each second edge 16, and the second gate driving circuit 50 and the first gate driving circuit 40 are respectively used for providing different driving signals.
Thus, the second gate driving circuit 50 and the first gate driving circuit 40 cooperate to meet the requirement of the display area 10 for different driving signals at the same time, and the applicability of the flexible display screen 100 can be improved, so that the flexible display screen 100 has a wide application prospect.
Referring to fig. 4, in some embodiments, the driving chip 30 is disposed on the lead region 20 and connected to the leads 21.
In this way, the driving chip 30 is directly disposed on the lead pad 20, so that the structure of the flexible display screen 100 is simpler. Specifically, the driving chip 30 may be disposed On the lead region 20 by a cog (chip On glass) technology, so that the lead region 20 of the driving chip 30 may be bent to the back surface 18 of the display region 10, so as to improve the screen occupation ratio of the flexible display screen 100.
Of course, in some embodiments, the driving chip 30 is disposed on the flexible circuit board 60, and the driving chip 30 is connected to the leads 21 through the flexible circuit board 60, as shown in fig. 1.
Specifically, the driving chip 30 may be disposed On the flexible circuit board 60 by cof (chip On flex) technology, and the flexible circuit board 60 may be connected to an external power supply to supply power to the display region 10.
In some embodiments, the first bending axis 12 is perpendicular to the second bending axis 13.
Thus, the space occupied by the flexible display screen 100 after being bent along the first bending axis 12 and the second bending axis 13 is small, which is beneficial to storage and transportation of the flexible display screen 100. In this embodiment, the first bending axis 12 is perpendicular to the first edge 15, and the second bending axis 13 is perpendicular to the second edge 16, so that the layout of the driving chip 30 is more convenient, and the manufacturing difficulty of the flexible display panel 100 is reduced.
In some embodiments, the display area 10 includes an OLED (Organic Light-Emitting Diode).
The OLED has advantages of low power consumption, low manufacturing cost, self-luminescence, and the like, so that the cost of the flexible display screen 100 can be reduced.
Referring to fig. 9, a display device 200 according to an embodiment of the present invention includes the flexible display screen 100 according to any one of the above embodiments.
In the display device, the driving chip 30 is disposed outside the first bending axis 12 and the second bending axis 13, so that interference between the flexible display screen 100 and the driving chip 30 during bending is avoided, and the flexible display screen 100 is prevented from being damaged during the bending process.
The display device 200 is an electronic device such as a television, a mobile phone, and a tablet computer having the flexible display screen 100.
In some embodiments, the display device 200 includes a housing 210 surrounding the flexible display 100, the housing 210 is formed with a first rotation axis 211 and a second rotation axis 212, the first rotation axis 211 coincides with the first bending axis 12, the second rotation axis 212 coincides with the second bending axis 13, and the housing 210 is capable of rotating around the first rotation axis 211 when the flexible display 100 is bent along the first bending axis 12 and capable of rotating along the second rotation axis 212 when the flexible display 100 is bent along the second bending axis 13.
In this way, the housing 210 may reduce the impact on the flexible display screen 100 to protect the flexible display screen 100, and in addition, the housing 210 may rotate when the flexible display screen 100 is bent, so as to prevent the housing 210 from being damaged.
Referring to fig. 10, in some embodiments, the housing 210 includes at least four sub-housings 213 connected in sequence along a circumferential direction of the housing 210, the sub-housings 213 on two sides of the first rotation axis 211 are rotatably connected together by a first rotating member (not shown), a center line of the first rotating member coincides with the first rotation axis 211, the sub-housings 213 on two sides of the second rotation axis 212 are rotatably connected together by a second rotating member 214, and a center line 2141 of the second rotating member 214 coincides with the second rotation axis 212.
In this way, the first rotating member and the second rotating member 214 can realize that all the sub-housings 213 of the display screen 100 are rotatably connected.
In the present embodiment, the number of the sub-housings 213 is four, and the number of the sub-housings 213 is the first sub-housing 213A, the second sub-housing 213B, the third sub-housing 213C, and the fourth sub-housing 213D.
In the example of fig. 10, when the upper and lower sub-housings 213 are connected, the center line 2141 of the second rotating member 214 coincides with the second rotation axis 212 so that the upper and lower sub-housings 213 can rotate relatively around the second rotating member 214. It should be noted that, as the connection structure of the two left and right sub-housings 213, reference may be made to the connection structure of the two upper and lower sub-housings 213. Therefore, it can be understood that when the left and right sub-housings 213 are connected, the center line of the first rotating member coincides with the first rotating axis 211 so that the left and right sub-housings 213 can relatively rotate around the first rotating member.
