Description

Display substrate, display device Technical Field

[0001] This article relates to but is not limited to the field of display technology, and specifically to a display substrate and a display device. Background Art

[0002] Flexible displays have been a research hotspot in recent years. With the mass production of foldable phones, researchers have begun researching stretchable displays, an upgraded version of foldable displays. Currently, stretchable display substrates use an island-bridge structure, with the display light-emitting units located in the island area and the connecting wires located in the bridge area, enabling the display panel to stretch. Currently, the connecting wires in the bridge area are typically fabricated on a flexible substrate (such as polyimide). Polyimide itself has a stretchability of only around 5%, which limits the ultimate stretchability of the display device.

Note that the embodiments can be implemented in a variety of different forms. A person of ordinary skill in the art can easily understand the fact that the methods and contents can be transformed into various forms without departing from the purpose and scope of the present disclosure. Therefore, the present disclosure should not be interpreted as being limited to the contents described in the following embodiments. In the absence of conflict, the embodiments in the present disclosure and the features in the embodiments can be arbitrarily combined with each other.

[0067] The scales of the figures in this disclosure can be used as a reference for actual processes, but are not limited to such. For example, the width-to-length ratio of the channel, the thickness and spacing of the various film layers, and the width and spacing of the various signal lines can be adjusted according to actual needs. The number of pixels in the display substrate and the number of sub-pixels in each pixel are not limited to the numbers shown in the figures. The figures described in this disclosure are merely schematic structural diagrams, and one embodiment of this disclosure is not limited to the shapes or values ​​shown in the figures.

[0068] In this specification, ordinal numbers such as “first”, “second” and “third” are provided to avoid confusion among constituent elements, and are not intended to limit the number.

[0069] In this specification, for convenience, words and phrases indicating orientation or positional relationships, such as "middle," "upper," "lower," "front," "back," "vertical," "horizontal," "top," "bottom," "inside," and "outside," are used to illustrate the positional relationships of constituent elements with reference to the accompanying drawings. This is merely for the purpose of facilitating the description of this specification and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present disclosure. The positional relationships of constituent elements may be appropriately changed depending on the direction in which each constituent element is described. Therefore, the present disclosure is not limited to the words and phrases described in the specification and may be appropriately replaced according to the circumstances.

[0070] In this specification, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections, indirect connections through intermediaries, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this disclosure.

[0071] In this specification, a transistor refers to a device that includes at least three terminals: a gate electrode, a drain electrode, and a source electrode. A transistor has a channel region between a drain electrode (drain electrode terminal, drain region, or drain electrode) and a source electrode (source electrode terminal, source region, or source electrode), and current can flow through the drain electrode, the channel region, and the source electrode. Note that in this specification, the channel region refers to the region through which current primarily flows.

[0072] In this specification, the first electrode can be a drain electrode and the second electrode can be a source electrode, or vice versa. The functions of "source electrode" and "drain electrode" may be interchanged when using transistors with opposite polarity or when the direction of current changes during circuit operation. Therefore, in this specification, "source electrode" and "drain electrode" can be interchanged, and "source terminal" and "drain terminal" can be interchanged.

[0073] In this specification, "electrically connected" includes components connected together via an element having some electrical function. There are no particular limitations on the "element having some electrical function" as long as it enables the transfer of electrical signals between the connected components. Examples of "element having some electrical function" include not only electrodes and wiring, but also switching elements such as transistors, resistors, inductors, capacitors, and other components with various functions.

[0074] In this specification, "parallel" refers to a state where the angle formed by two straight lines is greater than -10° and less than 10°, and thus also includes a state where the angle is greater than -5° and less than 5°. Furthermore, "perpendicular" refers to a state where the angle formed by two straight lines is greater than 80° and less than 100°, and thus also includes a state where the angle is greater than 85° and less than 95°.

[0075] In this specification, the terms "film" and "layer" may be interchanged. For example, "conductive layer" may be replaced with "conductive film." Similarly, "insulating film" may be replaced with "insulating layer."

[0079] FIG1 is a schematic diagram of the structure of a display device according to an embodiment of the present disclosure. As shown in FIG1 , the display device may include a timing controller, a data driver, a scan driver, a light-emitting driver, and a pixel array. The timing controller is respectively connected to the data driver, the scan driver, and the light-emitting driver. The data driver is respectively connected to a plurality of data signal lines (D1 to Dn). The scan driver is respectively connected to a plurality of scan signal lines (S1 to Sm). The light-emitting driver is respectively connected to a plurality of light-emitting signal lines (E1 to Eo). The pixel array may include a plurality of sub-pixels Pxij, where i and j may be natural numbers. At least one sub-pixel Pxij may include a circuit unit and a light-emitting unit. The circuit unit may include at least a pixel driving circuit, which is respectively connected to the scan signal lines, the light-emitting signal lines, and the data signal lines. The light-emitting unit may include a light-emitting device, which is connected to the pixel driving circuit of the circuit unit. In an exemplary embodiment, the timing controller may provide grayscale values ​​and control signals suitable for the specifications of the data driver to the data driver, may provide clock signals, scan start signals, etc. suitable for the specifications of the scan driver to the scan driver, and may provide clock signals, emission stop signals, etc. suitable for the specifications of the light-emitting driver to the light-emitting driver. The data driver can generate data voltages to be supplied to data signal lines D1, D2, D3, ..., and Dn using grayscale values ​​and control signals received from a timing controller. For example, the data driver can sample grayscale values ​​using a clock signal and apply data voltages corresponding to the grayscale values ​​to data signal lines D1 to Dn on a per-pixel basis, where n can be a natural number. The scan driver can generate scan signals to be supplied to scan signal lines S1, S2, S3, ..., and Sm by receiving clock signals, scan start signals, and the like from the timing controller. For example, the scan driver can sequentially supply scan signals having on-level pulses to scan signal lines S1 to Sm. For example, the scan driver can be configured as a shift register and can sequentially transmit scan start signals provided in the form of on-level pulses to the next-stage circuit under the control of a clock signal, where m can be a natural number. The light driver can generate emission signals to be supplied to light signal lines E1, E2, E3, ..., and Eo by receiving clock signals, emission stop signals, and the like from the timing controller. For example, the light emitting driver may sequentially provide emission signals having off-level pulses to the light emitting signal lines E1 to Eo. For example, the light emitting driver may be configured as a shift register and may generate emission signals by sequentially transmitting emission stop signals provided in the form of off-level pulses to the next stage circuit under the control of a clock signal. o may be a natural number. In an exemplary embodiment, the pixel array may be provided on a display substrate.

[0080] In an exemplary embodiment, the display substrate may employ a stretchable structure, comprising a plurality of island regions separated from each other and disposed on a flexible substrate, a hollow region between adjacent island regions, and a bridge region connecting adjacent island regions. Each island region may include one or more pixel units, each pixel unit including three (e.g., red, green, and blue) or four (e.g., red, green, blue, and white) light-emitting units emitting light of different colors. The hollow region is used to provide deformation space during stretching, and the hollow region only includes the flexible substrate, with the film layer on the flexible substrate in the hollow region removed. The bridge region is used for routing, and the bridge region includes leads that connect adjacent island regions.

[0081] Figure 2 is a schematic diagram of a planar structure of a display substrate according to an embodiment of the present disclosure. In an exemplary embodiment, as shown in Figure 2, the display substrate may include a first stretching region 400 and a second stretching region 500 located to one side of the first stretching region 400 in a second direction D2. The stretching rate of the first stretching region 400 is greater than the stretching rate of the second stretching region 500.

[0082] FIG3 is a schematic diagram of a planar structure of a display substrate according to an embodiment of the present disclosure. In an exemplary embodiment, as shown in FIG3 , the display substrate may include a display area 100 and a non-display area located around the display area. The non-display area of ​​the display substrate may include an electrical signal input area 200 located on one side of the display area 100 in the second direction D2 and a frame area 300 located on the other side of the display area 100. The first stretching area of ​​the display substrate includes the display area 100 and the frame area 300, and the second stretching area of ​​the display substrate includes the electrical signal input area 200. The stretching ratios of the display area 100 and the frame area 300 are greater than the stretching ratio of the electrical signal input area 200.

[0083] In an exemplary embodiment, the stretch rate of the hollowed-out area of ​​the first stretch region 400 is greater than the stretch rate of the hollowed-out area of ​​the second stretch region 500, resulting in a greater stretch rate in the first stretch region 400 than in the second stretch region 500. In the display substrate of the disclosed embodiment, by providing hollowed-out areas with different stretch rates in the first stretch region 400 and the second stretch region 500, the stretch rate of the first stretch region 400 is greater than that of the second stretch region 500. As a result, when the display substrate is stretched, the primary stretching deformation occurs in the first stretch region 400, reducing the stretching deformation in the second stretch region 500. This can reduce the risk of fracture of traces located in the second stretch region 500 and extend the life of the display substrate.

[0084] In an exemplary embodiment, the area of ​​the orthographic projection of the hollow area of ​​the first stretching region 400 on the plane of the display substrate is greater than the area of ​​the orthographic projection of the hollow area of ​​the second stretching region 500 on the plane of the display substrate, so that the stretching rate of the hollow area of ​​the first stretching region 400 is greater than the stretching rate of the hollow area of ​​the second stretching region 500, and thus the stretching rate of the first stretching region 400 is greater than the stretching rate of the second stretching region 500.

[0085] In an exemplary embodiment, the shape of the hollow area of ​​the first stretch zone 400 and the shape of the hollow area of ​​the second stretch zone 500 may be the same or different. For example, both may be strips of the same shape.

[0086] In an exemplary embodiment, the display substrate includes a display area 100 having a rectangular shape. In some embodiments, the display area 100 may also have a circular shape, an elliptical shape, or a polygonal shape such as a triangle, a pentagon, or the like.

[0087] Figure 4 is a schematic diagram of the planar structure of a display substrate according to an embodiment of the present disclosure. In an exemplary embodiment, as shown in Figure 4, the first stretching region may further include a buffer zone 600. Buffer zone 600 is a non-display area located on the side of the frame region 300 away from the display region 100. Buffer zone 600 is configured to withstand the tensile force of the display substrate during stretching, reducing tensile deformation of the frame region 300. This can reduce the risk of breakage of traces located in the frame region 300 and extend the life of the display substrate.

[0088] FIG5 is a schematic diagram of a planar structure of a display substrate according to an embodiment of the present disclosure. In an exemplary embodiment, as shown in FIG5 , the display area of ​​the display substrate may include a plurality of first island regions 11 spaced apart from each other, a first hollow region 12 located between adjacent first island regions 11, and a first bridge region 13 connecting adjacent first island regions 11 to each other. The plurality of first island regions 11 are arranged in a rectangular array. In the rectangular array, the plurality of first island regions 11 may be spaced apart along a first direction D1 to form a first island region row, and adjacent first island regions 11 in the first island region row are connected by the first bridge region 13. The plurality of second island regions 31 may be spaced apart along a second direction D2 to form a first island region column, and adjacent first island regions 11 in the first island region column are connected by the first bridge region 13. The first direction D1 and the second direction D2 are both parallel to the plane of the display substrate, and the first direction D1 intersects the second direction D2. For example, the first direction D1 and the second direction D2 are perpendicular to each other.

[0089] In an exemplary embodiment, the first island region 11 includes at least one pixel unit. The at least one pixel unit may include a first sub-pixel emitting a first color light, a second sub-pixel emitting a second color light, and a third sub-pixel emitting a third color light. Each sub-pixel may include a circuit unit and a light-emitting unit. The circuit unit may include at least a pixel driving circuit. The pixel driving circuit is respectively connected to a scan signal line, a data signal line, and a light-emitting signal line. The pixel driving circuit is configured to receive a data voltage transmitted by the data signal line under the control of the scan signal line and the light-emitting signal line and output a corresponding current to the light-emitting device.
