Because the power supply equipment and the electric device transmit energy in an inductive coupling mode, the power supply equipment and the electric device are not connected by wires, and no conductive contact is exposed. Therefore, the wireless charging technology improves the charging safety on one hand, and on the other hand, the electric device is not bound by a tangible wire, so that the use convenience of a user is improved.
Currently, wireless charging technology has been widely applied to various electronic display devices (e.g., mobile phones, computers, etc.).

The use of "first," "second," and similar terms in the embodiments of the disclosure is not intended to indicate any order, quantity, or importance, but rather to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items.
At present, a display device with a wireless charging function usually has the problems of large device thickness and complex assembly in a production process because a built-in wireless charging receiving coil needs to occupy a certain space.
Based on this, some embodiments of the present disclosure provide a display substrate 100. Referring to fig. 1, the display substrate 100 has a display area AA and a peripheral area BB disposed on at least one side of the display area. The display substrate 100 includes: a substrate 1, a plurality of first electrodes, and a wireless charging receiving coil 2. The plurality of first electrodes are disposed on one side of the substrate 1 and located in the display area AA, and a space is provided between every two adjacent first electrodes. The wireless charging receiving coil 2 is spirally distributed in the plurality of intervals.
Some implementations of the present disclosure utilize the interval between a plurality of first electrodes each other, with wireless receiving coil 2 that charges be the heliciform and distribute in a plurality of in the interval, can be guaranteeing to charge between receiving coil 2 and a plurality of first electrodes under the condition that overlap each other, do not shelter from each other, rationally improve the space utilization in the display substrate 100.
Illustratively, the display substrate 100 in the above embodiments is an electroluminescent substrate. The electroluminescent substrate further includes a plurality of sub-pixels in one-to-one correspondence with the plurality of first electrodes. Each sub-pixel comprises an electroluminescent device, and each first electrode is an anode of the corresponding electroluminescent device. The electroluminescent device is, for example, an Organic Light-Emitting Diode (OLED).
In the display substrate 100, the arrangement of the plurality of sub-pixels may be various. Optionally, referring to fig. 2, the sub-pixels in the above embodiment include a plurality of first color sub-pixels, a plurality of second color sub-pixels, and a plurality of third color sub-pixels. Wherein two first color sub-pixels, one second color sub-pixel and one third color sub-pixel constitute one pixel PX. In each pixel PX, the second color sub-pixel and the third color sub-pixel are located between the two first color sub-pixels, and the second color sub-pixel and the third color sub-pixel are distributed in a direction perpendicular to the arrangement direction of the two first color sub-pixels.
For example, with continued reference to fig. 2, the first color sub-pixel is a green sub-pixel G, the second color sub-pixel is a red sub-pixel R, and the third color sub-pixel is a blue sub-pixel B. Two green sub-pixels G, one red sub-pixel R, and one blue sub-pixel B are one pixel PX, that is, the display substrate 100 adopts a pixel structure in which the GGRB is arranged. Therefore, each pixel PX is of a symmetrical structure, and the plurality of pixels PV in adjacent rows are arranged in a staggered manner in the column direction, so that the first electrodes corresponding to the pixels PX have communicated intervals, and the wireless charging receiving coil 2 in a spiral arrangement is favorably accommodated.
In each pixel PX, the red subpixel R and the blue subpixel B are located between the two green subpixels G, and the red subpixel and the blue subpixel are distributed in a direction perpendicular to the arrangement direction of the two green subpixels. And, there is interval between two adjacent sub-pixels, that is to say, there is interval between the first electrodes corresponding to each sub-pixel one-to-one, that is to say, the anodes of the active light emitting devices corresponding to each sub-pixel. The wiring of the wireless charging receiving coil 2 is spirally distributed in the plurality of intervals, and the wireless charging receiving coil 2 and the anodes of the active light-emitting devices corresponding to the sub-pixels are not overlapped and shielded. In this way, it can be ensured that the display effect of each sub-pixel is not affected by the wireless charging reception coil 2.
It should be noted that the width of the wireless charging receiving coil 2 needs to be determined according to the size of the gap. Generally, the trace width of the wireless charging reception coil 2 is smaller than the size of the space. Optionally, the interval between the first electrodes respectively corresponding to two adjacent green sub-pixels G is 10 μm to 15 μm, and then the trace width of the wireless charging receiving coil 2 disposed in the interval is 3 μm to 5 μm. Thus, it can be ensured that the setting of the wireless charging receiving coil 2 does not affect the display effect of each pixel PX.
It should be noted that, in the above-mentioned pixel structure provided by the embodiment of the present disclosure, the area of the blue sub-pixel B is larger than that of the red sub-pixel R, and the area of the red sub-pixel R is larger than that of the green sub-pixel G. Since the luminous efficiency of the blue subpixel B is low, the luminous efficiency of the red subpixel R is higher than that of the blue subpixel B and lower than that of the green subpixel G. Therefore, the light emission efficiency of each color sub-pixel in each pixel PX can be effectively equalized by the above arrangement, thereby improving the display quality of the entire display substrate 100.
In some examples, the substrate 1 may be a flexible substrate (e.g., a light-transmitting plastic, an ultra-thin glass, etc.) or a rigid substrate (e.g., a sapphire substrate, a silicon carbide substrate, etc.). The type of the substrate 1 is selected according to actual needs, and is not limited by the embodiment of the present disclosure.
In some examples, the first electrode is a transparent electrode, which may be a transparent single-layer conductive film, or a multi-layer composite film, such as a stack of ITO/Ag/ITO, but not limited thereto.
In some examples, the wireless charging receiving coil 2 is a transparent induction coil, which may be made of the same material as the first electrode or a different transparent conductive material. The wireless charging receiving coil 2 can be disposed on the substrate 1 by laser, sputtering, evaporation, coating, electroplating or etching, for example.
In some embodiments of the present disclosure, the wireless charging receiving coil 2 is disposed on the same layer as the plurality of first electrodes.
Here, "disposed on the same layer" may refer to being formed by the same material and a single patterning process, or being formed by different materials and being located between two layers of the same material, or being formed by different materials and being in direct contact with the same layer. The patterning process includes a photolithography process, or a process including a photolithography process and an etching step. The photolithography process includes processes such as film formation (e.g., Chemical Vapor Deposition (CVD)), exposure, development, and the like, and forms a pattern using a photoresist, a mask, an exposure machine, and the like.
In this way, the wireless charging reception coil 2 can be integrated into the display substrate 100 by being disposed in the same layer as the plurality of first electrodes. Thus, it is not necessary to reserve a space for the wireless charging receiving coil 2 at another position of the display device having the display substrate 100, so that the thickness of the display device can be reduced, and the display device can be made thin and light.
In some embodiments, referring to fig. 1, the display substrate 100 further includes a flexible circuit board 3 located in the peripheral region BB. Wherein, the beginning and the tail end of the wireless charging receiving coil 2 are respectively electrically connected with the flexible circuit board 4. The flexible circuit board 3 is configured to receive a charging current formed by the wireless charging reception coil 3 in the case of wireless charging.
Optionally, referring to fig. 1, the tail end of the wireless charging receiving coil 2 is electrically connected to the flexible circuit board 4 through a first wire 4. The first lead 4 is disposed in the same layer as the plurality of first electrodes.
Here, the material of the first conductive line 4 may be a transparent or opaque conductive line, and the material may be a metal material (e.g., gold, silver, aluminum, nickel, copper, chromium, etc.) or a conductive metal oxide material (e.g., indium tin oxide).
Optionally, referring to fig. 1, the display substrate 100 further includes a plurality of signal lines, and the plurality of signal lines include a plurality of gate lines 5 and a plurality of data lines 7. Among them, a plurality of gate lines 5 extend in a row direction of the pixels PX, and a plurality of data lines 7 extend in a column direction of the pixels PX. The starting end of the wireless charging receiving coil 2 is electrically connected with the flexible circuit board 3 through a second lead 6. In some examples, the second conductive line 6 is disposed at the same layer as the plurality of gate lines 5 and has the same extending direction. In other examples, the second conductive line 6 is disposed in the same layer as the plurality of data lines 7 and has the same extending direction.
Of course, the second conductive line 6 is not limited to be disposed in the display substrate 100, and may be disposed alone or in the same layer as other electrodes or signal lines, so as not to affect the display of the display area AA.
In addition, please refer to fig. 1, the display substrate 100 further includes: a fan-out wiring portion 12 electrically connected to a plurality of signal lines, a shift register circuit portion 13 electrically connected to a plurality of gate lines, low-level voltage lines 8 and high-level voltage lines 9 electrically connected to the flexible circuit board 3, respectively, and a flexible package circuit (Chip On Pi, COP for short) 11. In addition, the end of the fan-out trace portion 12 away from the display area AA is typically further provided with a line detection end 10 and/or an electrostatic shielding end.
In some embodiments, the display substrate 100 is an OLED substrate. Each subpixel includes an OLED and a pixel driving circuit electrically connected to an anode of the OLED. The structure of the pixel driving circuit can be selected according to actual requirements, and is generally formed by connecting a Thin Film Transistor (TFT) and a capacitor in series and parallel. The structure of the thin film transistor can be selected according to actual requirements, for example, the thin film transistor is an N-type transistor or a P-type transistor, for example, the thin film transistor is a top gate structure or a bottom gate structure, and the like. Taking a thin film transistor as an example of a thin film transistor with a top gate structure, the thin film transistor generally includes an active layer, a gate insulating layer, a gate electrode, an interlayer insulating layer, a source electrode, and a drain electrode, wherein the drain electrode and the source electrode are both electrically connected to the active layer, and the drain electrode is electrically connected to an anode of a corresponding OLED.
Here, according to the structure of the display substrate 100, the manufacturing process of the display substrate 100 may be performed by referring to a thin film forming process (e.g., a mask process) in the related art, and will not be described in detail.
In summary, some embodiments of the disclosure combine the pixel arrangement on the display substrate 100 to utilize the interval between the first electrodes in the display area AA to spirally dispose the wireless charging receiving coil 2 in the display substrate 100. And the starting end and the tail end of the wireless charging receiving coil 2 are respectively and electrically connected with the flexible circuit board 3, so that the flexible circuit board 3 receives the charging current formed by the wireless charging receiving coil 2 under the condition of wireless charging. That is, in the embodiment of the present invention, the receiving end of the wireless charging (i.e., the wireless charging receiving coil 2) is integrated in the display substrate 100, so that there is no need to reserve a space for the wireless charging receiving coil 2 at other positions of the display device having the display substrate 100, and thus the thickness of the display device can be reduced, the display device can be thinned, and the assembly process of the display substrate 100 can be simplified.

The display device Crt includes the display substrate 100 as described in the above embodiments, and the energy storage cell 14 electrically connected to the flexible circuit board 3 in the display substrate 100.

For example, the energy storage battery 14 may be a lithium battery, a nickel metal hydride battery, or the like having a function of storing electric energy.
