Embodiments of the present invention provide a display panel, which is a stretchable display panel, and the display panel is stretchable along at least one direction. The display panel may be an Organic Light-Emitting Diode (OLED) display panel, or may be other types of display panels such as Micro-LEDs (Micro-LEDs) and quantum dots. The present invention is not limited with respect to the type of display panel. The display panel of the embodiments of the present invention may be presented in various forms, some examples of which will be described below.
Fig. 1 is a schematic top view of a display panel according to an embodiment of the invention. The display panel 100 of the embodiment of the invention is stretchable in the first direction Y. The display panel 100 has a display area AA and a circuit arrangement area NA located on the peripheral side of the display area AA. The display panel 100 includes a plurality of sub-pixels 111 arranged in the display area AA, each sub-pixel 111 including a light emitting unit and a pixel circuit electrically connected to the light emitting unit, the plurality of sub-pixels 111 being arranged in a plurality of rows and columns along a first direction Y and a second direction X, wherein the first direction Y and the second direction X cross each other, and only the second direction X is shown perpendicular to the first direction Y. The circuit setting area NA is used for setting a driving circuit, and the driving circuit is connected to the pixel circuit to control each light emitting unit to emit light for display.
The display area AA includes first hard islands 11 arranged in an array and first elastic bridges 12 disposed between the first hard islands 11, at least one sub-pixel 111 is disposed on the first hard island 11, and the first hard island 11 is connected to the adjacent first hard island 11 and the circuit setting area NA through the first elastic bridge 12. The first elastic bridge 12 is made of a stretchable material, so that the display area AA is stretchable, and each sub-pixel 111 is disposed on the first hard island 11, so that when the display area AA is stretched, the performance of the light emitting unit and the pixel circuit can be prevented from being affected.
The circuit setting area NA includes second hard islands 21 arranged at intervals along the first direction Y and second elastic bridges 22 connecting adjacent second hard islands 21, and the second hard islands 21 are provided with driving circuits. The driving circuit is electrically connected to the pixel circuit. The second elastic bridge 22 is made of stretchable material, the circuit setting area NA can be stretched, the driving circuit is arranged on the second hard island NA, and when the circuit setting area NA is stretched, the performance of the driving circuit can be prevented from being affected.
In the first direction Y, the distribution amount of the first hard island is M, that is, the first hard island 21 in the display area AA may be divided into M rows; the distribution amount of the second hard islands 21 is N, that is, the second hard islands 21 in the circuit area NA may be divided into N rows, and M ≠ N. Wherein M is an integer greater than or equal to 2, and N is an integer greater than or equal to 2. The distribution amount herein refers to the number of rows in which the first hard islands 11 and the second hard islands 21 are arranged in the stretchable direction of the display panel 100.
In practical design, the inventors found that when the distribution amounts of the first hard island 11 in the display area AA and the second hard island 21 in the circuit area NA in the stretching direction of the display panel 100 are set to be the same, the stretching performance of the display area AA and the stretching performance of the circuit area NA are not consistent, and the two areas are restricted with each other, which affects the stretching characteristics of the display panel 100 as a whole.
The difference in the shape of the first rigid island 11 in the display area AA and the second rigid island 21 in the circuit area NA, and the difference in the shape of the first elastic bridge 12 connecting the adjacent first rigid islands 11 in the display area AA and the second elastic bridge 22 connecting the adjacent second rigid islands 21 in the circuit area NA cause the tensile properties of both areas to be inconsistent. Therefore, in this embodiment, the distribution amounts of the first hard island 11 and the second hard island 21 in the stretching direction of the display panel 100 are set to be different, so as to adjust the stretching performance of the two regions, ensure that the stretching performance of the two regions is consistent, and further improve the stretching characteristic of the whole display panel 100.
In some embodiments, as shown in fig. 1, the circuit disposing area NA may be disposed at one side of the display area AA in the second direction X, and a plurality of driving circuits are disposed at one side of the display area AA to control the sub-pixels 111 of the display area AA.
In this embodiment, the circuit setting area NA is disposed on one side of the display panel 100, so that the frame of the display panel 100 can be reduced, and the screen occupation ratio of the display panel 100 can be improved.
In other embodiments, please refer to fig. 2, wherein fig. 2 is a schematic top view of a display panel according to another embodiment of the present invention. The circuit arrangement area NA may be disposed at opposite sides of the second direction X of the display area AA. The circuit arrangement area NA is disposed on two opposite sides of the display panel 100, and a driving signal is provided to the pixel circuit of each sub-pixel 111 through the first connection line 13 in a bilateral driving manner to control the light emitting display of each sub-pixel 111, so that the voltage drop of the first connection line 13 can be reduced, and the display uniformity of the display panel 100 can be improved.
In some embodiments, with continued reference to fig. 1, 3, and 4, fig. 3 is a cross-sectional view a-a of fig. 1, and fig. 4 is a cross-sectional view B-B of fig. 1. The display panel 100 includes a stretchable substrate 30, each of the hard islands and the elastic bridges may be disposed on the stretchable substrate 30, and in particular, the second hard islands 21 and the second elastic bridges 22 located between adjacent second hard islands 21 are disposed in the circuit disposing region NA of the stretchable substrate 30, and the cascade connection between the driving circuits on the adjacent second hard islands 21 is achieved through the elastic bridges 22. First rigid islands 11 and first elastic bridges 12 positioned between adjacent first rigid islands 11 are disposed in the display area AA of the stretchable substrate, and signals of the driving circuit are transmitted to each pixel circuit of the display area AA through the first elastic bridges 12 to control each sub-pixel 111 to emit light for display. Only a partial cross-sectional view of the display area AA is illustrated in fig. 3 and 4, and it is understood that the second hard island 21 and the second elastic bridge 22 of the circuit arrangement area NA are arranged in a manner similar to that of the first hard island 11 and the first elastic bridge 12 of the display area AA.
In other embodiments, the elastic bridge may not be disposed on the stretchable substrate, that is, in a structure obtained by peeling the elastic bridge corresponding to the embodiment in fig. 1 from the stretchable substrate, the first hard island 11 is connected by the first elastic bridge 12, the second hard island 21 is connected by the second elastic bridge 22, and is connected by the first elastic bridge 12 and the second hard island 21, and a region where each hard island and the elastic bridge are not disposed is a hollow region, so as to further enhance the stretching property of the display panel 100.
In still other embodiments, the first elastic bridge 12 includes a first connection line 13, the second elastic bridge 22 includes a second connection line 23, the second connection line 23 can enable cascading between the driving circuits of the adjacent second hard islands 21, and signals of the driving circuits are transmitted to the pixel circuits of the display area AA through the first connection line 13 to control the sub-pixels 111 to emit light for display. The first connection line 13 may include, for example, at least one of a scan line scan, a data line data, a light emission control signal line emit, and a power supply voltage signal line VDD. In an embodiment, the first elastic bridge 12 and the second elastic bridge 23 may be made of a metal material to form the first connection line 13 and the second connection line 23, so as to implement a signal transmission function. In another embodiment, please refer to FIG. 5, wherein FIG. 5 is another B-B cross-sectional view of FIG. 1. The first elastic bridge 12 and the second elastic bridge 22 may be made of an elastic insulating material, and the first connection line 13 is formed on the first elastic bridge 12, and the second connection line 23 is formed on the second elastic bridge 22, so that a signal transmission function is realized through the first connection line 13 and the second connection line 23. In this embodiment, the first elastic bridge 12 and the second elastic bridge 22 can also protect the first connection line 13 and the second connection line 23, respectively. Only a partial sectional view of the display area AA is illustrated in fig. 5, and it is understood that the second hard island 21, the second elastic bridge 22, and the second connection line 23 of the circuit arrangement area NA are arranged in a similar manner to the first hard island 11, the first elastic bridge 12, and the first connection line 13 of the display area AA. In some embodiments, the first elastic bridge 12 comprises a first connection line 13, and the first connection line 13 may be at least one of a curved line, a fold line, and a splice line formed by the curved line and the fold line. The first connecting lines 13 are disposed in the bending structure, so that the stretchable property of the first connecting lines 13 can be increased, and the stretchable property of the display area AA can be further increased, thereby preventing the signal transmission from being affected by the breakage of the first connecting lines 13 when the display panel 100 is stretched, and further affecting the display effect of the display panel 100. It should be noted that the elastic bridge may also be the connection line itself, that is, after the connection line is fabricated on the flexible carrier between the hard islands, the flexible carrier of the connection line is removed, so that only the connection line composed of the signal lines is retained between the hard islands. In other embodiments, the second elastic bridge 22 includes a second connection line 23, and the second connection line 23 may be at least one of a curved line, a fold line, and a splice line formed by the curved line and the fold line. The second connection line 23 is configured as the above-mentioned bending structure, so that the stretchable characteristic of the second connection line 23 can be increased, and the stretchable performance of the circuit configuration area NA can be further increased, so as to prevent the second connection line 23 from being broken when the display panel 100 is stretched, so as to affect the transmission of signals between adjacent driving circuits, and further affect the display effect of the display panel 100.
Referring to fig. 6 and 7, fig. 6 is a schematic top view of a display panel according to another embodiment of the present invention; FIG. 7 is a schematic diagram of local interconnects between a first hard island and a second hard island according to an embodiment of the present invention. The second elastic bridge 22 comprises a second connection line 23 and the first elastic bridge 12 comprises a first connection line 13. The second connection line 23 may be used to connect the driving circuits on the connected second hard island 21, the second connection line 23 is generally wider, and the line width of the second connection line 23 is greater than the line width of the first connection line 13. In some embodiments, the distribution amount M of the second hard island 21 and the distribution amount N of the first hard island 11 satisfy the relationship M > N. For the example of the display panel shown, the number of rows of the second hard island 21 is greater than the number of rows of the first hard island 11.
In this embodiment, the distribution amount M of the second hard island 21 is greater than the distribution frame N of the first hard island 11, so that the circuit arrangement area NA has more second elastic bridges 22 between the adjacent second hard islands 21, when the display panel 100 is stretched, the second elastic bridges 22 of the circuit arrangement area NA have smaller stretching amount, which can realize that the circuit arrangement area NA has larger stretching amount as a whole, and at this time, the deformation amount of the second connection lines 23 on the second elastic bridges 22 is smaller and is not easy to break. Therefore, in this embodiment, the distribution amount M of the second hard island 21 is greater than the distribution amount N of the first hard island 11, so that the tensile characteristic of the circuit arrangement area NA can be increased, and the protection of the second connection line 23 is facilitated.
In an embodiment, the distribution amount M of the second hard islands 21 and the distribution amount N of the first hard islands 11 satisfy a relation M ═ a × N, where a is an integer greater than or equal to 2.
In this embodiment, the distribution amount M of the second hard island 21 and the distribution amount N of the first hard island 11 are in an integral multiple relationship, which is beneficial to the regular arrangement of the first hard island 11 and the second hard island 21 on the display panel 100, so as to simplify the preparation difficulty. Furthermore, the sub-pixels 111 of the first hard island 11 can be controlled by the same number of driving circuits of the second hard island 21, so as to simplify the connection mode.
For example, the distribution amount M of the second hard island 21 and the distribution amount N of the first hard island 11 satisfy the relation M-2 × N. With continued reference to FIGS. 6 and 7, the number of rows of the second hard islands 21 is 2 times the number of rows of the first hard islands 11.
In this embodiment, the distribution amount M of the second hard island 21 is 2 times of the distribution amount N of the first hard island 11, which can meet the requirement of the circuit setting area NA for stretching property, and meanwhile, the number of the second hard islands 21 is not too many, which does not increase the difficulty of process preparation, and the space occupied by the second hard island 21 is relatively small, which does not increase the frame area of the display panel 100.
Further, as shown in fig. 6 and 7, the first hard islands 11 are arranged along the second direction X to form a plurality of first hard island rows 10, and each first hard island row 10 is correspondingly connected to two second hard islands 21. That is, the sub-pixels 111 of each first hard island row 10 are controlled by the driving circuits on the corresponding two second hard islands 21.
In this embodiment, each first hard island row 10 is correspondingly connected to two second hard islands 21, and specifically, each first hard island row 10 may be connected to two adjacent second hard islands 21 according to the arrangement sequence of the first hard island row 10 and the second hard island 21 along the first direction Y. The arrangement of the first connecting lines 13 connecting the first hard island 11 and the second hard island 21 is facilitated, the first connecting lines 13 and/or the second connecting lines 23 can be prevented from being dense and too many crossing through reasonable layout, the product yield can be improved, and the reliability of the display panel 100 can be improved.
In some embodiments, the second hard island 21 may further include first sub-second hard islands 211 and second sub-second hard islands 212, and the first sub-second hard islands 211 and the second sub-second hard islands 212 are alternately arranged along the first direction Y. A gate driving circuit is disposed on the first sub-second hard island 211 to be electrically connected to the gate line of the display area AA, and provide a signal for controlling the gate of the thin film transistor to the pixel circuit; the second sub second hard island 212 is provided with a light emitting control circuit electrically connected to the light emitting control signal line of the display area AA to control the light emitting duration of the light emitting unit of the sub-pixel 111. In this embodiment, at least one gate driving circuit may be disposed on the first sub-second hard island 211, and at least one light emitting control circuit may be disposed on the second sub-second hard island 212.
In this embodiment, each sub-pixel 111 may be electrically connected to a corresponding gate driving circuit and a corresponding light emitting control circuit, and the first sub-second hard islands 211 and the second sub-second hard islands 212 are alternately arranged in the first direction Y, so that the connection manner between the gate driving circuit, the light emitting control circuit, and the pixel circuit of the sub-pixel 111 may be simplified.
In an embodiment, four sub-pixels 111 may be disposed on each first hard island, and the four sub-pixels 111 are divided into two rows and two columns of sub-pixels 111. Two gate driving circuits may be disposed in each first sub-second hard island 211, two light emitting control circuits may be disposed in each second sub-second hard island 212, and one first sub-hard island 211 and one second sub-hard island 212 are correspondingly connected to each first hard island row 10.
In another embodiment, please refer to fig. 8, which illustrates a local connection between a first hard island and a second hard island according to another embodiment of the present invention. Each first hard island 11 may be provided with four sub-pixels 111, and the four sub-pixels 111 are divided into two rows and two columns of sub-pixels 111. One gate driving circuit may be disposed in each first sub-second hard island 211, one light emitting control circuit may be disposed in each second sub-second hard island 212, and each first hard island row 10 correspondingly connects two first sub-hard islands 211 and two second sub-hard islands 212.
The sizes of the first hard islands 11 in the display area AA may be equal or may not be equal. The sizes of the second hard islands 21 in the circuit arrangement area NA may be equal or different. In some embodiments, the sizes of the first hard islands 11 and the second hard islands 21 of the display panel 100 are all equal to each other, so as to simplify the manufacturing difficulty.
In some embodiments, referring to fig. 7, the width W2 of the second hard island 21 in the first direction Y is less than the width W1 of the first hard island 11 in the first direction Y. In this embodiment, when the length of the display panel 100 along the first direction Y is constant, a large number of second hard islands 21 may be disposed in the circuit disposing area NA along the first direction Y.
Further, in some embodiments, please refer to fig. 9, in which fig. 9 is a schematic structural diagram of a circuit configuration area according to an embodiment of the present invention. The second hard islands 21 may be arranged in a single row in the first direction Y, that is, the second hard islands 21 are arranged in the first direction Y to form a second hard island row 20, which may reduce the frame width of the display panel 100, facilitate the realization of a narrow frame, and improve the screen occupation ratio.
In some embodiments, the orthographic projection of the second elastic bridge 22 along the first direction Y is located within the orthographic projection of the second rigid island 21 along the first direction Y. The second elastic bridge 22 can be prevented from occupying an area outside the space occupied by the second hard 21 island along the first direction Y, which is beneficial to realizing a narrow frame and improving the screen occupation ratio of the display panel 100. Taking the circuit layout area NA shown in fig. 9 as an example, the circuit layout area NA includes the display panel 100 having the second hard island 20, and the second elastic bridge 22 is located in the area defined between the two dotted lines in the figure.
In other embodiments, please refer to fig. 10 and 11, fig. 10 is a schematic top view illustrating a display panel according to still another embodiment of the present invention; fig. 11 is a schematic structural diagram of a circuit layout area according to another embodiment of the present invention. The second hard islands 21 may be arranged along the first direction Y to form at least two second hard island columns 20, and the second hard islands 21 included in adjacent second hard island columns 20 partially overlap in the second direction X. The circuit layout area NA is illustrated as having two second hard island rows 20. The second hard islands 21 in the adjacent second hard island rows 20 are partially overlapped in the second direction X, the length of the circuit setting area NA in the first direction Y can be reduced, and each second hard island 21 is arranged in a "Z" shape in the first direction, and the second elastic bridges 22 between the second hard islands 21 of each adjacent second hard island row 20 are also distributed in a "Z" shape, so that the setting areas of the second elastic bridges 22 are more dispersed, which is beneficial to the dispersion of tensile stress when the circuit setting area NA is stretched, and the stretching reliability of the circuit setting area NA is improved.
Moreover, the second hard islands 21 are arranged in a plurality of rows in a cross manner, and one second hard island row 20 is split into two or more second hard island rows 20, so that more second hard islands 21 are distributed in a unit size, and the hard islands distributed in a staggered manner can reduce the size of the circuit setting area NA along the first direction Y. By arranging the second elastic bridge 22 between adjacent second hard islands 21 in different columns, the length and width of the second elastic bridge 22 are not compressed, the circuit characteristics of the driving circuit are not affected, and the elastic characteristics of the second elastic bridge 22 can be maintained. Referring to fig. 9 and fig. 11, the circuit setting area NA in fig. 9 is provided with a single row of second hard islands 21, assuming that the number of the second hard islands 21 in fig. 9 and fig. 11 is 2n, the width of the second hard islands 21 is W1, the width between adjacent second hard islands 21 in fig. 9 is H1, and the width between adjacent second hard islands 21 in the same row in fig. 11 is H2, then in fig. 9, the length L1 occupied by a single second hard island column 20 in the first direction Y is 2n W1+ (2n-1) H1, in fig. 11, the length L2 occupied by two second hard island columns 20 in the first direction Y is n W1+ (n-1) H2+ H3, and since the second hard islands 21 in different columns in fig. 11 overlap in the second direction X, then the width of one hard island in fig. 11 is less than the width of the adjacent second hard island 3621 in the second hard island 9 and the second hard island 1 in the second direction X, therefore, L2 is much smaller than L1. As can be seen from the above analysis, in the embodiment in which the plurality of second hard island rows 20 are disposed in the circuit arrangement area NA, the size of the circuit arrangement area NA in the first direction Y can be effectively reduced.
In some embodiments, please continue to refer to fig. 11, the circuit layout area NA includes the display panel 100 having a plurality of second hard island columns 20, the layout position of the second connection lines 23 may be relatively large, and the second elastic bridges 22 may be located in a space occupied by an area between all the second hard island columns 20 and the adjacent hard island columns 20 along the first direction Y, that is, an area defined between two vertical dotted lines in the drawing. The second elastic bridge 22 can be prevented from occupying an area outside the space occupied by the second hard 21 island along the first direction Y, which is beneficial to realizing a narrow frame and improving the screen occupation ratio of the display panel 100.
In some embodiments, please refer to fig. 12, in which fig. 12 is a schematic structural diagram of a circuit layout area according to still another embodiment of the present invention. In the circuit arrangement region NA, the adjacent second hard islands 21 are connected to each other by at least two second connection lines 23. In this embodiment, the connecting lines connecting the adjacent second hard islands 21 are divided into a plurality of second connecting lines 23, so that the overall tensile properties of the second connecting lines 23 between the adjacent second hard islands 21 can be improved.
In the above embodiment, the shapes of the first hard island 11 and the second hard island 21 are not limited. In some embodiments, the first hard island 11 and the second hard island 21 may be arranged in a rectangle. The second hard island 21 may be provided with a Vertical Shift Register (VSR), the driving circuit may be specifically provided in the VSR, and since the VSR has a generally rectangular structure, in order to provide more second hard islands 21 in the circuit arrangement area NA, the short side of the VSR on the second hard island 21 extends in the first direction Y.
In some embodiments, the display panel 100 may be further stretchable along the second direction X, in this embodiment, the display panel 100 is stretchable along the second direction X by the display area AA being stretchable along the second direction X, while the circuit arrangement area NA may be stretchable only along the first direction Y and may not be stretchable along the second direction X, such that when the display panel 100 is stretched along the second direction Y, only the length of the display area AA along the second direction X is increased, and the width of the circuit arrangement area NA of the display panel 100 is not increased, so as to improve the screen ratio of the display panel 100. Moreover, the distribution amount M of the second hard islands 21 of the circuit arrangement area NA of the display panel 100 is greater than the distribution amount N of the first hard islands 11 of the display area AA, and when the display panel 100 is stretched along the first direction Y, the circuit arrangement area NA does not limit the stretching capability of the display panel 100.
