Embodiments of the present application provide a touch display panel, which includes but is not limited to the following embodiments.
In one embodiment, as shown in fig. 1, the touch display panel 00 includes a touch layer 100 and at least one power generation layer 200, the touch layer 100 is disposed on the at least one power generation layer 200, and the touch layer 100 is used for applying pressure to the at least one power generation layer 200; each of the at least one power generation layer 200 is arranged to detour up and down along a first direction 01, the first direction 01 is parallel to the touch layer 100, and the at least one power generation layer 200 is configured to convert the pressure into electric energy acting on the touch display panel 00, so as to increase the endurance time of the touch display panel 00.
The power generation layer 200 and the touch layer 100 may be disposed in a contact manner or in a non-contact manner.
Specifically, when the at least one power generation layer 200 includes one power generation layer, the one power generation layer 200 may be disposed in a whole layer, that is, the one power generation layer 200 may be completely overlapped with the touch layer 100, so as to ensure that a contact area between the one power generation layer 200 and the touch layer 100 is maximized, and to convert the pressure into the electric energy applied to the touch display panel 00 to the maximum extent. Of course, the one power generation layer 200 may be disposed in a non-integral layer, that is, the one power generation layer 200 may partially overlap with the touch layer 100, for example, the one power generation layer 200 may be disposed opposite to a region with a high probability of being touched, such as a central region or an edge region of the touch layer 100, so as to save cost and maximally improve the probability of converting the pressure into the electric energy applied to the touch display panel 00.
It should be noted that the touch layer 100 is disposed on the at least one power generation layer 200, and each power generation layer 200 of the at least one power generation layer 200 is disposed to detour up and down along the first direction 01, and the surface shape of the touch layer 100 close to the at least one power generation layer 200 may be consistent with the shape of the upper surface of the at least one power generation layer 200, so that the at least one power generation layer 200 and the touch layer 100 are in sufficient contact, so as to improve the stability between the touch layer 100 and the at least one power generation layer 200, and to maximally improve the probability of the pressure being converted into the electric energy acting on the touch display panel 00.
In an embodiment, as shown in fig. 2, the touch display panel 00 further includes a pixel layer 300, the pixel layer 300 is disposed on a side of the power generation layer 200 away from the touch layer 100, the pixel layer 300 includes a plurality of sub-pixels 301, and a gap 02 is formed between two adjacent sub-pixels 301 in the plurality of sub-pixels 301; the at least one power generation layer 200 is disposed opposite to the gap 02.
It is to be understood that since the at least one power generation layer 200 is disposed opposite to the gap 02, that is, the at least one power generation layer 200 includes a plurality of power generation layers 201, each of the plurality of power generation layers 201 may be disposed opposite to the corresponding gap 02.
Specifically, the pixel layer 300 may include a plurality of gaps 02, one power generation layer 201 may be disposed in each gap 02, and the size of the power generation layer 201 is not greater than the size of the corresponding gap 02, so as to avoid affecting the light transmittance of the touch display panel 00. Further, the size of the power generation layer 201 in the different gaps 02 may be large enough, so that the power generation layers 201 in the different gaps 02 may be connected to each other, so that the power generation layers 201 may be integrally formed, and the gaps 02 are fully utilized, so as to improve the probability that the pressure is converted into the electric energy acting on the touch display panel 00 to the maximum extent on the premise that the light transmittance is not affected.
In one embodiment, as shown in fig. 3 to 5, two adjacent rows of sub-pixels 302 in the plurality of sub-pixels 301 have a first gap 03 therebetween, and two adjacent columns of sub-pixels 303 have a second gap 04 therebetween; the at least one power generation layer 200 is disposed opposite to at least one of the first gap 03 and the second gap 04.
It is to be understood that, since the plurality of sub-pixels 301 includes a plurality of row sub-pixels 302 and a plurality of column sub-pixels 303, the pixel layer 300 may include a plurality of the first gaps 03 and a plurality of the second gaps 04, i.e., the at least one power generation layer 200 includes a plurality of power generation layers 201. Of course, the plurality of sub-pixels 301 may be arranged in other directions than rows and columns to form other gaps, and similarly, the plurality of power generation layers 201 may be disposed to face the corresponding other gaps, that is, the plurality of power generation layers 201 may be arranged in parallel and at intervals in other directions.
Specifically, as shown in fig. 3, when the at least one power generation layer 200 is disposed opposite to the first gap 03, each of the plurality of power generation layers 201 may be disposed opposite to the corresponding first gap 03, that is, the plurality of power generation layers 201 are parallel to each other and arranged in a row.

Specifically, as shown in fig. 5, when the at least one power generation layer 200 is disposed opposite to the first gap 03 and the second gap 04, the at least one power generation layer 200 may include a plurality of first power generation layers 202 and a plurality of second power generation layers 203. The plurality of first power generation layers 202 correspond to the plurality of first gaps 03 one by one, and each first power generation layer 202 in the plurality of first power generation layers 202 may be disposed opposite to the corresponding first gap 03, that is, the plurality of first power generation layers 202 are arranged in a row; the plurality of second power generation layers 203 and the plurality of second gaps 04 correspond to each other one by one, and each of the plurality of second power generation layers 203 may be disposed opposite to the corresponding second gap 04, that is, the plurality of second power generation layers 203 are arranged in a column.

It is to be noted that, when the at least one power generation layer 200 includes one power generation layer or a plurality of power generation layers, each of the power generation layers 200 includes a plurality of top portions 204 and a plurality of connection portions 205.
It can be understood that, since the plurality of tops 204 are close to the touch layer 100, that is, the pressure applied by the touch layer 100 to the at least one power generation layer 200 acts on the plurality of tops 204 first, if each top 204 is in a convex shape, the pressure of the plurality of tops 204 can be increased, when other conditions are consistent, the sensitivity of each power generation layer 200 to the pressure can be improved, and even if the pressure is smaller, by reducing the facing area of the plurality of tops 204 and the touch layer 100, the power generation layer 200 can generate a larger reaction to convert the pressure into electric energy acting on the touch display panel. Specifically, the top portion 204 may be a rounded protrusion or a sharp protrusion, or the top portion 204 may include a plurality of protrusion shapes, and the plurality of protrusion shapes may include at least one of a rounded protrusion and a sharp protrusion.
Further, the connecting portions 205 are configured to connect two corresponding adjacent top portions 204, so as to achieve integrity and continuity of each power generation layer 200, and transmit pressure acting on the top portions 204 to multiple regions of the corresponding power generation layer 200, so that the pressure fully acts on the power generation layers 200, each region of each power generation layer 200 generates a corresponding reaction, which contributes to converting the pressure into electric energy acting on the touch display panel, and improves efficiency of converting the pressure into the electric energy acting on the touch display panel. Specifically, the shape of the plurality of connection portions 205 may include at least one of a straight line or a curved line.
Further, as shown in fig. 7, in order to improve the uniformity of each of the power generation layers 200, each of the connection portions 205 may include a bottom portion 2051 and a wiring portion 2052. The bottom portions 2051 are far away from the touch layer 100, the bottom portions 2051 are recessed, that is, the arrangement directions of the bottom portions 2051 and the top portions 204 are opposite, the bottom portions 2051 and the top portions 204 can be alternately arranged along the first direction 01, further, the sizes of the bottom portions 2051 and the top portions 204 can be consistent, two ends of each bottom portion 2051 are respectively provided with one connecting line portion 2052, and each connecting line portion 2052 is used for connecting one end of the corresponding bottom portion 2051 with one section of the corresponding top portion 204, so as to achieve the integrity and the continuity of each power generation layer 200. The connecting line portion 2052 may include at least one of a straight line and a curved line, and further, the connecting line portion 2052 may be configured as a curved line, or the length of the connecting line portion 2052 may be within a preset range, so as to increase the volume of the power generation layer 200 and improve the efficiency of converting the pressure into the electric energy applied to the touch display panel.
In one embodiment, as shown in fig. 8, each of the power generation layers 200 includes: a functional layer 206, wherein the functional layer 206 is configured to convert the pressure into electric energy applied to the touch display panel 00; a first insulating layer 207, wherein the first insulating layer 207 is disposed on a side of the functional layer 206 close to the touch layer 100, and the first insulating layer 207 is used for insulating the functional layer 206 from the touch layer 100.
In one embodiment, the material of the functional layer 206 comprises a piezoelectric material. The piezoelectric material is a crystalline material that generates a voltage between two end surfaces when subjected to a pressure, that is, when the functional layer 206 is subjected to the pressure applied by the touch layer 100, a voltage difference is generated between two ends of the functional layer 206, that is, the functional layer 206 may be similar to a power supply, and a current may also be generated inside the functional layer 206.
Specifically, the constituent material of the functional layer 206 may include an inorganic piezoelectric material, an organic piezoelectric material, or a composite piezoelectric material, where the inorganic piezoelectric material may include a piezoelectric crystal and a piezoelectric ceramic, the organic piezoelectric material may include polyvinylidene fluoride, and the composite piezoelectric material may include at least two different piezoelectric materials.
It can be understood that, the touch layer 100 is used for converting an external pressure signal into an electrical signal, that is, the touch layer 100 has conductivity and transmits the electrical signal, and the inside of the functional layer 206 is also subjected to the pressure applied by the touch layer 100 to generate a current, that is, the functional layer 206 also has conductivity, that is, the first insulating layer 207 can prevent the current in the functional layer 206 from interfering with the electrical signal in the touch layer 100. The first insulating layer 207 may completely cover the functional layer 206, or the first insulating layer 207 at least completely covers the touch layer 100 to ensure insulation between the functional layer 206 and the touch layer 100, and the first insulating layer 207 may include at least one of silicon nitride, silicon oxide, and resin.
In an embodiment, as shown in fig. 9, when the other film layers 300 on the side of the functional layer 206 away from the touch layer 100 also transmit an electrical signal, each of the power generation layers 200 further includes: the second insulating layer 208 is disposed on a side of the functional layer 206 away from the touch layer 100, the second insulating layer 208 is used for insulating the functional layer 206 from other film layers 300, and the other film layers 300 are disposed on corresponding film layers of the power generation layer 200 away from the touch layer 100.

The second insulating layer 208 may completely cover the functional layer 206, or the second insulating layer 208 at least completely covers the other film layer 300 to ensure insulation between the functional layer 206 and the other film layer 300, and a constituent material of the second insulating layer 208 may include at least one of silicon nitride, silicon oxide, and resin.
In an embodiment, when the other film layer 300 on the side of the functional layer 206 away from the touch layer 100 does not transmit an electrical signal, for example, when the other film layer 300 is a flat layer or a passivation layer or other film layer with insulation properties, the functional layer 206 may be embedded in the other film layer 300, that is, the other film layer 300 may replace the second insulating layer 208 or even the first insulating layer 207 in addition to performing its own function.

It can be understood that the pressure applied by the touch layer 100 on the power generation layer 200 is not constant, but changes irregularly with time, and completely depends on an uncontrollable external factor, so that the voltage or current generated by the power generation layer 200 itself is an alternating current, does not conform to the power required by the touch display panel 00, and cannot directly act on the touch display panel 00.
Specifically, the power generation layer 200 includes a first port 402 and a second port 403, the integration portion 401 includes a third port 404 and a fourth port 405, first wires 05 are connected between the first port 402 and the third port 404 and between the second port 403 and the fourth port 405, a current generated by the power generation layer 200 itself is transmitted to the integration portion 401 through the first wires 05, and the integration portion 401 can convert an alternating current generated by the power generation layer 200 itself into a direct current that can be used by the touch display panel 00, and the direct current serves as the target electric energy.
