Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Referring to fig. 1, fig. 1 is a schematic diagram of a foldable display panel in the prior art. A driving chip (IC) of the display panel is bonded to a lower step of the display panel in the related art, and the data line 310 extends from the display panel to the lower step and is electrically connected to the IC. However, during the folding of the display panel, the data line at the 30 position is deformed as the display panel is folded. In the long-term use process, the data line at 30 is broken due to repeated bending, so that the upper half of the display panel cannot transmit the signal of the data line 310, and the display panel fails.
The application provides a display panel, solves folding display panel and breaks the line easily and leads to the problem of inefficacy.
As shown in fig. 2, fig. 2 shows a schematic view of a display panel in an embodiment of the present application; the display panel comprises a first display area 10 and a second display area 20, wherein a folding shaft 300 is arranged between the first display area 10 and the second display area 20;
the first display area 10 includes a first side 101 disposed to cross the folding axis 300, and a second side 102 disposed to be opposite to the first side; the first driving circuit VSR1 is disposed on the first side 101, and the first driving chip IC1 is disposed on the second side 102; the second display area 20 includes a third side edge 103 disposed to cross the folding axis 300, and a fourth side edge 104 disposed opposite to the third side edge 103; the second driving circuit VSR2 is disposed on the third side 103, and the second driving chip IC2 is disposed on the fourth side 104; the first side 101 is aligned with the fourth side 104 and the second side 102 is aligned with the third side 103.
In the present application, the folding shaft 300 divides the display panel into two display regions, and the respective driving circuit and the driving chip are disposed in the two display regions to realize the disconnection of the signal line near the folding shaft 300 in time, so that the normal display can still be realized. For example, at the folding axis 300, the data line is broken, the gate driving signal is provided by the first driving circuit VSR1 for the pixel located in the first display region in this application, and the data signal provided by the first driving chip IC1 can be displayed normally; the pixels in the second display region are provided with gate driving signals by the second driving circuit VSR2, and the data signals provided by the second driving chip IC2 enable normal display.
In addition, only the left and right sides of the display panel need to be provided with a non-display area to set a driving circuit and bind a driving chip, and the upper and lower sides can implement complete frameless.
With continued reference to fig. 2, in another embodiment of the present application, the second driver chip IC2 is electrically connected to the first driver circuit VSR1 for providing a driving signal to the first driver circuit VSR 1; the second driving chip IC2 supplies data signals to the second display area 20;
the first driving chip IC1 is electrically connected to the second driving circuit VSR2 for providing driving signals to the second driving circuit VSR2, and the first driving chip IC1 provides data signals to the first display region 10;
further, the driving signals include a start signal, a clock control signal, and a power supply signal.
Since the operation of the driving circuit requires signals such as the start signal STV, the clock signals CK and XCK, and the power supply signals VGH and VGL, which are required to be pulled from the driving chip IC to the driving circuit. Since the driving circuit and the driving chip are respectively disposed on both sides of the display panel in the first display region or the second display region, if the first driving chip is wired to the second driving chip, a long signal line is required, which may cause a large voltage drop. And these power lines must be relatively wide to reduce voltage drop, which in turn causes the bezel to widen. Therefore, the length of the signal line is greatly reduced by the second driving chip, the first driving circuit and the second driving chip and by directly pulling the second driving chip to the first driving circuit. The signal line 50 of the driving signal in the folding area can be set to be 1.5 times or more of the width of the driving signal line in the driving circuit area, so that the minimum wiring voltage drop is ensured on one hand, and some stress release spaces can be arranged on the signal line 50 of the driving signal on the other hand, and the risk of wire breakage caused by bending is reduced.
In addition, the second driving chip IC2 provides data signals to the second display area 20, while the driving signals of the second display area 20 are provided by the second driving circuit VSR2, and the driving signals of the VSR2 are provided by the first driving chip IC1, so that signal synchronization of the first driving chip IC1 and the second driving chip IC2 is required to drive the display of the second display area. In this embodiment, it may be that the CPU of the display device has a synchronization function, or a synchronization control signal may be provided in the flexible circuit board.
With continued reference to fig. 2, the foldable display panel of the present application includes pixel circuits 40 arranged in an array; the first display region 10 includes a first data line 110 extending in a first direction and a first data link line 111 extending in a second direction; the first data line 110 is connected to the corresponding pixel circuit 40, and the first data connection line 111 is used for connecting the first data line 110 and the first driver chip IC 1; the second display area 20 includes a second data line 210 extending in a first direction and a second data link line 211 extending in a second direction; the second data line 210 is connected with the corresponding pixel circuit 40, and the second data connection line 211 is used for connecting the second data line 210 and the second driving chip IC 2;
in a display panel, in order to realize progressive scanning, a row of scanning lines are usually opened, and all data lines transmit signals at the same time, so that the data lines are usually required to be arranged perpendicular to the scanning lines. The driving chip is arranged on the opposite side of the driving circuit, the data lines and the scanning lines are arranged in a normal mode, and the data lines and the driving chip are connected through the data connecting lines to complete the mode of realizing progressive scanning.
Referring to fig. 3 in an embodiment of the present application, fig. 3 is a schematic view of a display panel according to another embodiment of the present application.
In the present embodiment, in the first display region 10, k first data lines 110 are included in a direction pointing from the first driving circuit VSR1 to the first driving chip IC 1;
in the second display area 20, k second data lines 210 are included in a direction pointing from the second driving circuit VSR2 to the second driving chip IC 2; the ith first data line is correspondingly connected with the (k-i + 1) th second data line, wherein i is a positive integer and is less than or equal to k. The data lines of the first display area and the second display area are correspondingly connected, and are driven by the two driving chips IC1 and IC2, so that the driving capability is greatly enhanced. Also, if the data line is broken in the vicinity of the folding axis 300 due to repeated bending once, the first driving chip IC1 thereof can still drive the first display region pixels, and the second driving chip IC2 can still drive the pixels of the second display region 20. Thereby avoiding the problem of display panel failure caused by repeated bending. The reliability of the foldable display panel is greatly increased.
Further, the length of the first data link line 111 connecting the mth first data line 110 and the first driver chip IC1 is L1, and the length of the second data link line 211 connecting the (k-m + 1) th second data line 210 and the second driver chip IC2 is L2;
the length of the first data link line 111 connecting the nth data line 110 and the first driver IC1 is L3, and the length of the second data link line 211 connecting the (k-n + 1) th data line 210 and the second driver IC2 is L4; l1+ L2 ═ L3+ L4, where m and n are positive integers, and m and n are not more than k.
In this embodiment, each data line is driven by two ICs together, and according to the setting mode of this application, make the total length of the data link line that each data line and IC are connected the same, make the parasitic capacitance and the voltage drop condition of each data line the same, and then make the demonstration of whole folding display panel be homogeneous.
Furthermore, along the first direction, the lengths of the first data connecting lines are distributed in an arithmetic progression; and the lengths of the second connecting data lines are distributed in an arithmetic progression along the first direction.
In another embodiment of the present application, the data line 110 of the first display region 10 and the data line 210 of the second display region 20 may be disposed in an insulated manner. Referring to fig. 4, fig. 4 is a schematic view of a display panel according to another embodiment of the present application. In the first display region 10, k first data lines are included in a direction pointing from the first driving circuit VSR1 to the first driving chip IC 1; in the second display area 20, k second data lines are included in a direction pointing from the second driving circuit VSR2 to the second driving chip IC 2; each first data line is insulated from each second data line.
The display panel according to the present application may be disposed in the vicinity of the folding axis 300, and the first data line 110 and the second data line 210 are insulated from each other, and there is no direct connection but a gap therebetween, so that the gap may release stress when the display panel is folded, thereby ensuring that the data lines are not broken.
In addition, the two ICs of the present application can be driven simultaneously to increase the refresh rate of the display panel. In the conventional display panel, as shown in fig. 1, when refreshing a frame, the driving circuit needs to be turned on in sequence from the first row until the last row is finished. In the present application, the first driver IC1 controls the second driver circuit VSR2 to complete half of the refresh cycle, and the second driver IC1 controls the first driver circuit VSR1 to complete half of the refresh cycle, so that only half of the refresh time is needed for one frame, and therefore, the present application can achieve the effects of shortening the refresh time and increasing the refresh rate by the insulated arrangement of the first data line 110 and the second data line 210. High refresh rate (high frame rate) display panels play a crucial role in electronic competition devices.
Furthermore, the display panel may have uneven display due to the different lengths of the signal connection lines corresponding to each data line. In this embodiment, each first data connection line 111 extends from the 1 st first data line 110 to the kth first data line 110; each first data connection line 111 is connected with the corresponding first data line 110 through a via hole; each second data link line 211 extends from the 1 st data line 210 to the kth data line 210; and each second data link line 211 is connected to the corresponding second data line 210 through a via hole. In this embodiment, the data connection lines have the same length, and thus the parasitic capacitances of the pixels in the display panel are consistent across the entire display panel, thereby increasing the display uniformity of the display panel.
In another embodiment of the present application, the first data link line connecting the pth first data line 110 and the first driver IC1 has a length of L5 and a resistance of R1; the length of a first data connecting line connecting the q-th first data line and the first driving chip is L6; resistance R2; l5< L6, and 0.9 ≦ R1/R2 ≦ 1. Because the length of the data line connecting line is different, the resistance is different, and further the delay and the load of the data line correspondingly connected with the data line are different, so that the display is not uniform. In this embodiment, the resistance of the data connection line with a short length is set to be almost the same as the resistance of the data connection line with a long length, so that the load and the delay are approximately the same, and the display is more uniform.
Optionally, the width of the first data link line 111 connecting the pth first data line 110 and the first driver IC1 is D1; the width of the first data link line 111 connecting the q-th first data line 110 and the first driver chip IC1 is D2; d1 < D2. Therefore, the resistors of the two resistors can be close to each other without extra winding, the layout space is saved, and great change is not needed. The same is true for the second display region, and the resistances of the longer second data link lines 211 and the shorter data link lines 211 may be set to be close, thereby achieving display uniformity of the entire display panel.
Optionally, please refer to fig. 6, fig. 6 is a schematic diagram of a display panel according to another embodiment of the present application. The first data connection line 210 connecting the pth first data line 110 and the first driver chip IC1 is electrically connected to the first capacitor; the first data link line 111 connecting the q-th first data line 110 and the first driver chip IC1 is electrically connected to the second capacitor; the capacitance value of the first capacitor is larger than that of the second capacitor. The load of the longer first data connecting line is close to or the same as the load of the shorter first data connecting line by increasing the capacitance load on the first data connecting line, so that the display of the whole display panel is uniform.
In another embodiment of the present application, as shown in fig. 7, fig. 7 is a schematic view of a display panel according to another embodiment of the present application. The first display area 10 includes a first bending region 31 adjacent to the folding axis 300, and the second display area 20 includes a second bending region 32 adjacent to the folding axis 300; the first driving circuit VSR1 does not overlap the first bending region 31, and the second driving circuit VSR2 does not overlap the second bending region 32. Because the driving circuit VSR comprises a large number of transistors and capacitor devices and is connected in a complex mode, the stability of the display panel can be greatly improved by avoiding the driving circuit VSR from being arranged in a display area, and the driving circuit is prevented from being out of work due to bending.
Further, the first display area 10 includes a first edge 11 that is not parallel to the first side; the first driving circuit VSR includes a first shift register unit VSR _ 1; the number of the first shift register units VSR _1 at the first edge 11 is larger than the number of pixel rows at the first edge;
the second display area comprises a second edge 21 which is not parallel to the third side edge; the second driving circuit comprises a second shift register unit VSR _ 2; the number of the second shift register units VSR _2 at the second edge 21 is larger than the number of pixel rows at the second edge; each stage of shift register cells can drive a row of pixels. In this application, no shift register unit is disposed in the first bending area 31 and the second bending area 32, and the length of the first edge of this embodiment is greater than the length along the first side edge when the first edge is not disposed, so that more shift register units can be disposed on the first edge, and the shift register units in the first bending area can be sequentially translated upwards to dispose the first edge. The width of the frame is not required to be increased for placement. Taking fig. 7 as an example, there are 5 rows of pixels in the first edge 11 area, but 7 stages of shift register units are disposed along the first edge 11, and the shift register units of the first bending region 31 are sequentially shifted upward to the first edge. The second edge condition is the same, and is not described herein.
The display device of the present application may be any device including the display panel as described above, including but not limited to a cellular phone 1000, a tablet computer, a display of a computer, a display applied to a smart wearable device, a display applied to a vehicle such as an automobile, and the like as shown in fig. 8. The display device is considered to fall within the scope of protection of the present application as long as the display device includes the driving unit included in the display device disclosed in the present application.
The display panel enables the fan-out section of the second display area to be overlapped with the driving circuit, so that a frame corresponding to the second display area of the frame is narrowed.
It will be appreciated by a person skilled in the art that the scope of the invention as referred to in the present application is not limited to the embodiments with a specific combination of the above-mentioned features, but also covers other embodiments with any combination of the above-mentioned features or their equivalents without departing from the inventive concept.
