Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Example 1:
as shown in fig. 2 to 7, the present embodiment provides a touch substrate, which includes a plurality of touch electrodes 1 and touch lines 2 correspondingly connected to the touch electrodes 1, the touch substrate includes: the touch panel comprises a first conductive layer and a second conductive layer which are arranged on a substrate, wherein the first conductive layer comprises a plurality of touch electrodes 1; the second conductive layer comprises a plurality of touch control lines 2 corresponding to the touch control electrodes 1; the touch control lines 2 are electrically connected with the corresponding touch control electrodes 1; and the orthographic projection of the touch control lines 2 on the substrate is overlapped with the orthographic projection of part of the touch control electrodes 1 on the substrate.
As shown in fig. 2, in the present embodiment, the touch substrate may include a frame area where the amount of the touch area is located at the periphery of the touch area. The touch area comprises a plurality of sub-touch areas for arranging the touch electrodes 1. The touch electrode 1 is connected to the touch line 2 to transmit a touch signal to a processor (e.g., a chip) through the touch line 2, so as to process the touch signal.
In the touch substrate provided by this embodiment, the touch lines 2 are disposed in the touch area, so as to avoid occupying the frame area, thereby facilitating the realization of the narrow frame or the frameless frame of the touch substrate. In addition, in the touch area of the touch substrate, the touch electrode 1 and the touch line 2 are respectively disposed on two conductive layers in this embodiment, so that the orthographic projections of the touch line 2 and the touch electrode 1 on the substrate can be overlapped, thereby avoiding the touch line 2 from occupying an extra area, ensuring the effective touch area of the touch substrate, and avoiding the influence on occupying the display area and avoiding the occurrence of a blind area on the touch display panel when the touch substrate is applied to the touch display panel.
Optionally, the touch substrate provided in this embodiment includes a self-contained touch substrate.
Optionally, the touch substrate may further include: a dielectric layer 3 between the first conductive layer and the second conductive layer; the dielectric layer 3 has an opening, and the touch electrode 1 is connected to the touch line 2 through the opening. The material of the dielectric layer 3 may include: polyimide, and the like. As shown in fig. 6, in the touch substrate provided in this embodiment, two conductive layers may be disposed on the substrate, and the two conductive layers are separated by a dielectric layer 3. One of the conductive layers is a touch electrode layer, the other conductive layer is a touch line layer, and the openings are formed in the dielectric layer 3, so that the touch electrodes 1 can be connected with the touch lines 2, and the touch electrodes 1 and the corresponding touch lines 2 can be connected in an overlapping manner to transmit touch signals. It can be understood that, in the touch substrate provided in this embodiment, the projection of the touch line 2 on the base preferably falls within the projection of the touch electrode 1 on the base, in this case, the layer where the touch line 2 is located and the layer where the touch electrode 1 is located do not need to be distinguished from each other in terms of the vertical position relationship, either of them may be above or below, and the vertical position relationship between the touch electrode 1 and the touch line 2 in fig. 6 is only an illustration.
Optionally, in this embodiment, the material of the touch electrode 1 may include metal, such as conductive metal, e.g., copper, silver, and the like. Meanwhile, the material of the touch line 2 may also include a conductive metal. In this embodiment, the structures of the touch electrode 1 and the touch line 2 can be formed through a patterning process.
Optionally, in this embodiment, the sub-touch areas are arranged in an array, each sub-touch area is correspondingly provided with one touch electrode 1, and the touch lines 2 extend along the column direction. As shown in fig. 3 and 4, the touch substrate includes a plurality of sub-touch areas arranged in an array, and each sub-touch area is provided with a touch electrode 1; the touch lines 2 extend in the column direction. The touch electrodes 1 need to transmit a touch signal to the chip through the touch lines 2, and the touch lines 2 need to extend from the corresponding touch electrodes 1 to the IC terminal of the touch substrate (the lower end of the touch substrate in fig. 2 and 3) to be connected to the chip. In order to shorten the length of the touch lines 2 as much as possible, in the embodiment, the touch lines 2 preferably extend along the column direction and directly extend to the IC end of the touch substrate, so as to reduce the transmission impedance and ensure the touch effect.
In the conventional touch display substrate, in order to ensure a touch effect, the layer where the touch electrode 1 is located is usually located on one side of the display device (i.e., the light emitting side and the display side of the display device) away from the substrate, in order to avoid the influence of the touch electrode 1 on the normal display function of the touch display substrate and ensure the touch effect, optionally, as shown in fig. 4 and 5, the touch electrode 1 has a grid 11-shaped structure, and a hollow area of the grid 11 is used for corresponding to a pixel unit, so that light emitted by the display device of the pixel unit can pass through the pixel electrode to be displayed.
Optionally, in this embodiment, the shape of the touch electrode 1 includes a rectangular, a diamond, or a special-shaped pattern. In this embodiment, the shape of the touch electrode 1 refers to the overall contour of the touch electrode 1, and does not conflict with the structure of the touch electrode 1, which is a front structure or a hollow structure. As shown in fig. 3 and 4, the touch electrode 1 in the present embodiment may have a diamond shape, and may specifically have a diamond-shaped metal mesh 11 structure. Alternatively, as shown in fig. 7, the shape of the touch electrode 1 in this embodiment may be irregular. The shape of the touch electrode 1 is only required to meet the touch requirement, and is not particularly limited in this embodiment.
In this embodiment, as shown in fig. 3 to 5, the touch lines 2 can directly extend from the corresponding touch electrodes 1 to the IC end of the touch substrate. The projections of the touch lines 2 and the corresponding touch electrodes 1 on the substrate have a certain overlapping area, so that the touch lines 2 and the touch electrodes 1 can be directly overlapped by opening in the dielectric layer 3, and the structure and the preparation process of the touch substrate are simplified.
Further optionally, the orthographic projection of the touch line 2 in the sub-touch area and the orthographic projection of the touch electrode 1 falling into the same sub-touch area. As shown in fig. 4 and 5, in the embodiment, the touch electrodes 1 are hollow patterns and are uniformly arranged in the touch area of the touch substrate, the touch lines 2 are also arranged in the touch area, and the touch electrodes 1 are hollow patterns. In order to avoid the configuration of the touch line 2 from blocking the hollow area of the touch electrode 1 as much as possible, it is preferable in this embodiment that the projection of the touch line 2 on the substrate overlaps the projection of the touch electrode 1 on the touch substrate. It can be understood that, in the touch substrate provided in the present embodiment, the touch electrodes 1 are distributed in each word touch region, a certain gap is formed between the touch electrodes 1, and the touch lines 2 at least extend from the positions corresponding to the touch electrodes 1 to the IC end of the touch substrate to be connected to the chip. Therefore, most of the touch lines 2 need to pass through one or more sub-touch areas where the touch electrodes 1 corresponding to the touch lines are located to reach the IC terminal. Optionally, in this embodiment, when the touch line 2 passes through any one of the sub-touch areas, the orthographic projection of the touch line 2 in the sub-touch area overlaps with the orthographic projection of the touch electrode 1 located in the touch area, or is covered by the orthographic projection of the touch electrode 1 located in the touch area, so that when the touch line 2 is applied to the display substrate, the influence on the light emission of the pixel unit is avoided as much as possible.
Specifically, as shown in fig. 2 and 3, the touch line 2 may directly extend in only one direction, or the touch line 2 may extend in more than one direction within an allowable range, as long as its projection in the sub-touch region falls within the projection of the touch electrode 1 in the touch region.
It can be understood that the touch substrate provided in the present embodiment may be a touch display substrate, and when the touch substrate is a touch display substrate, the touch lines 2 should be as thin as possible to avoid affecting the visual effect of the display image entering human eyes through the touch layer. Since the touch line 2 provided in this embodiment is disposed in the touch area and also disposed in the corresponding display area, when the touch line 2 and the touch electrode 1 are stacked, the visibility of the pattern of the touch electrode 1 is enhanced to a certain extent, which may affect the display effect.
In order to make the overall display effect of the touch display substrate more uniform, as an embodiment, it is preferable that the shape and the size of each touch line 2 are the same when the condition allows for each touch line 2, so as to avoid the problem of non-uniform display in different areas of the touch display substrate caused by different lengths or difficult thicknesses of the touch lines 2. Specifically, in the touch substrate provided in this embodiment, each touch line 2 may extend from one end of the touch substrate to the other end, for example, from one end away from the IC end of the touch substrate to the IC end. It can be understood that, although the touch lines 2 extend longer and correspond to more touch areas (i.e. overlap with more touch electrodes 1), since the touch lines 2 are uniformly arranged as a whole, when displaying, the display effect can be ensured as long as the whole display brightness is adjusted, and the adverse situation that the user obviously feels different brightness in different areas due to the fact that the touch lines 2 in partial areas are overlapped with the touch electrodes 1 more densely can not occur.
It should be noted that, in this embodiment, the projection of the touch line 2 on the substrate is preferably overlapped with the projection of the touch electrode 1 on the substrate. Since the structure of the touch electrode 1 is preferably a mesh structure as shown in fig. 4 and 5, in this embodiment, the touch lines 2 extend along the column direction or extend along any direction, which means that the overall extending direction of the touch lines 2 extends along the column direction or extends along any direction (as shown in fig. 2 and 3), and in the enlarged view, the touch lines 2 may actually be a bending line pattern corresponding to the mesh structure of the touch electrode 1 as shown in fig. 4 and 5, and are not necessarily straight lines in a strict sense.
Optionally, the overlapping area of each touch electrode 1 is the same as that of the corresponding touch line 2. In the transmission process of the touch signal, the transmission impedance is related to the overlapping area of the touch electrode 1 and the touch line 2, and in this embodiment, in order to keep the transmission impedance of each touch area of the touch substrate consistent, the overlapping area of each touch electrode 1 and the corresponding touch line 2 is preferably the same. It should be noted that the touch signal transmission impedance is also related to the length, material, thickness, and other factors of the touch line 2, and the size of the overlapping area between the touch electrode 1 and the touch line 2 is adjusted according to the specific situation in practical application, which is not limited in this embodiment.
Example 2:
the present embodiment provides a touch display panel, including any one of the touch substrates provided in embodiment 1.
Optionally, the touch substrate further includes a pixel unit, and the pixel unit includes a display device, a driving transistor, and the like. The display device is located on one side of the touch electrode close to the substrate, namely the touch electrode is located on the light emitting side of the display device, and light emitted by the display device penetrates through the touch electrode to be displayed.
The touch display panel provided by the embodiment can be used in any product or component with a display function, such as a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator and the like.
In the touch display panel provided in this embodiment, the touch substrate provided in embodiment 1 is adopted, and the touch lines are disposed in the touch area and overlapped with the touch electrodes, so that the touch lines are prevented from occupying a frame area, which is beneficial to realizing a narrow frame or no frame of the touch substrate. In addition, in the touch area of the touch substrate, the touch electrode and the touch line are respectively arranged on the two conductive layers in the embodiment, so that the orthographic projection of the touch line and the touch electrode on the substrate can be overlapped, the touch line is prevented from occupying an extra area, the effective touch area of the touch substrate is ensured, meanwhile, the occupation of a display area can be avoided, the light emission of a display device cannot be influenced, and the occurrence of a blind area of the touch display panel can be effectively avoided.
It will be understood that the above embodiments are merely exemplary embodiments taken to illustrate the principles of the present invention, which is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
