Abstract

The application also discloses a mask plate for manufacturing the touch substrate and a method for manufacturing the touch substrate.
Description
Technical Field
The present invention relates to the field of display technology, and more particularly, to a touch substrate, a mask plate for manufacturing the touch substrate, and a method of manufacturing the touch substrate.
Background
Touch display panels have found wide application in the display field. The conventional touch display panel includes a plurality of first touch electrodes arranged in columns and a plurality of second touch electrodes arranged in rows, each column forming a plurality of first conductive channels and each row forming a plurality of second conductive channels. Two first touch electrodes adjacent along a column are connected by a first bridge. Two second touch electrodes adjacent along a row are connected by a second bridge. When a finger touches a point on the touch display panel, a capacitor formed by the finger is superimposed on the touch panel capacitor, resulting in a change in capacitance of the touch panel capacitor. In the mutual capacitive touch display panel, the first electrode may be a sensing electrode and the second electrode may be a driving electrode. Upon detection of a touch event, the mutual capacitance touch display panel sequentially inspects the first electrode array and the second electrode array. Based on the change in capacitance caused by the touch event, coordinates of the first and second electrodes being touched may be determined. Touch resolution is related to the distance between adjacent conductive channels. The smaller the distance between adjacent conductive channels, the higher the touch resolution.

Detailed Description
The present disclosure will be described in more detail with reference to the following examples. It should be noted that the following description of some embodiments presented herein is for the purposes of illustration and description only. It is not intended to be exhaustive or to be limited to the precise form disclosed.
Fig. 1A to 1C are diagrams illustrating conventional touch electrode patterns. Referring to fig. 1A to 1C, a conventional touch electrode has a pattern composed of straight lines connected by sharp edges. Static charge tends to accumulate around these sharp edges, resulting in electrostatic breakdown in the touch panel. For example, static charge accumulation around sharp edges can result in a relatively high product value (ADC) of capacitance and resistance around sharp edges. When ADC is too high, the charge time of the touch panel increases, the report rate (report rate) of the touch panel decreases, and it is more difficult to adjust F/W of the touch integrated circuit, all of which adversely affect the performance of the touch screen. Electrostatic breakdown can cause shorting between touch electrodes (e.g., sense electrodes and drive electrodes) and cause the touch display panel to malfunction. In addition, for example, in an add-on (add-on) touch display panel, such as a monolithic glass-scheme touch display panel, touch electrodes having a straight line pattern may be associated with serious Mura defects and poor blanking effects (blanking).
In addition, the present disclosure provides a novel touch substrate, a mask blank for manufacturing the same, and a method of manufacturing the same, which substantially obviate one or more problems due to limitations and disadvantages of the related art. In one aspect, the present disclosure provides a touch substrate. In some embodiments, the touch substrate includes a plurality of touch electrodes having rounded corners, e.g., substantially all corners of substantially all boundaries of the plurality of touch electrodes are substantially rounded corners. In some embodiments, the touch substrate includes a plurality of touch electrodes having continuously smoothly curved boundaries, e.g., substantially all of the boundaries of the plurality of touch electrodes are continuously smoothly curved. In some embodiments, the touch substrate includes a plurality of touch electrodes having rounded corners and continuously smoothly curved boundaries, e.g., substantially all corners of substantially all boundaries of the plurality of touch electrodes are substantially rounded corners; and substantially all of the boundaries of the plurality of touch electrodes are continuously smoothly curved.
As used herein, the term "rounded" in the context of an electrode boundary means that the corners of the boundary have been smoothed into a substantially circular shape, e.g., the corners transition smoothly, stepwise, from a first direction to a second direction. The substantially circular shape may be, for example, in the form of a substantially circular shape (e.g., a semicircle, a quarter circle), a substantially arc, a substantially parabolic shape, or any combination thereof, so long as any sharp edges can be avoided. Optionally, the angle is a lobe. Alternatively, the angle is a reentrant angle. Optionally, the corner is a corner of a protruding portion. Optionally, the corner is a corner of a recessed portion. Optionally, the rounded corners are rounded corner protrusions. Optionally, the rounded corners are rounded concave portions.
As used herein, the term "continuous smooth curve" in the context of an electrode boundary means that the boundary has substantially no straight portions. The boundary may be comprised of a single continuous smooth curve, or may include a plurality of continuous smooth curves connected by one or more rounded corners (e.g., rounded corner protrusions, rounded corner depressions, or a combination thereof). Optionally, the boundary substantially comprises a plurality of continuous smooth curves connected adjacently by rounded corners. For example, the boundary may have a circular shape (e.g., a semicircle, a quarter circle), a sinusoidal shape, an elliptical shape, a parabolic shape, an arc shape, or any combination thereof.
In one aspect, the present disclosure provides a plurality of touch electrodes having rounded corners. Fig. 2A to 2D are diagrams illustrating touch electrode patterns in some embodiments. Referring to fig. 2A, in an embodiment, a touch substrate includes a first touch electrode layer having a plurality of rows of first touch electrodes 1 and a second touch electrode layer having a plurality of columns of second touch electrodes 2. The plurality of rows of first touch electrodes 1 and the plurality of columns of second touch electrodes 2 cross each other to form a plurality of crossing points IS. Adjacent first touch electrodes 1 are electrically connected at each of the crossing points IS by a plurality of first bridges 4, and adjacent second touch electrodes 2 are electrically connected at each of the crossing points IS by a plurality of second bridges 5. The first bridge 4 and the second bridge 5 are electrically insulated by an insulating layer 6. For example, the first touch electrode 1 may be a touch scan electrode (Tx), and the second touch electrode 2 may be a touch sense electrode (Rx). Each row of transparent first touch electrodes 1 may be connected to a touch scan line, and each column of transparent second touch electrodes 2 may be connected to a touch sense line. Near each intersection IS, a mutual capacitance IS generated between each row of first touch electrodes 1 and each column of second touch electrodes 2. When a finger or object touches near the intersection IS, some of the mutual capacitance between the rows and columns couples to the finger or object, reducing the capacitance at that intersection. The touch location may be detected based on a change in mutual capacitance.
Referring to fig. 2A, adjacent two rows of first touch electrodes 1 are insulated from each other at an insulation intersection B in a column direction, and adjacent two columns of second touch electrodes 2 are insulated from each other at the insulation intersection B in a row direction.
Referring to fig. 2A, in an embodiment, the touch substrate further includes a fill pattern layer having a plurality of fill patterns 3 (e.g., a plurality of dummy electrodes). The boundaries of the plurality of fill patterns 3 are substantially complementary to the corresponding portions of the adjacent touch electrodes. For example, the boundaries of the plurality of filling patterns 3 are substantially complementary to the corresponding portions of the adjacent first touch electrode 1 and second touch electrode 2. The first touch electrode 1, the second touch electrode 2, and the filling pattern 3 are electrically insulated from each other.
In some embodiments, the touch substrate includes a plurality of touch electrodes having rounded corners, e.g., substantially all corners of substantially all boundaries of all touch electrodes are substantially rounded corners. Fig. 2B is a diagram showing a structure of a touch substrate corresponding to the region "a" in fig. 2A. As shown in fig. 2A and 2B, the corners of the first touch electrode 1 are substantially rounded. The angle may be a convex rounded angle P1 (e.g., a rounded protruding portion P1) or a concave rounded angle R1 (e.g., a rounded recessed portion R1). As shown in fig. 2A, all corners of the boundary of the first touch electrode 1 are rounded so that there is no sharp edge in the boundary.
Fig. 2C is a diagram showing the structure of a touch substrate corresponding to the region "B" in fig. 2A in some touch substrates. The region "B" corresponds to an insulation intersection at which adjacent two rows of the first touch electrodes 1 are insulated from each other along the column direction, and adjacent two columns of the second touch electrodes 2 are insulated from each other along the row direction. As shown in fig. 2A and 2C, any protruding portions of the adjacent two rows of the first touch electrodes 1 and the adjacent two columns of the second touch electrodes 2 are rounded at the insulating intersection B. The corners may be convex or concave. For example, in fig. 2C, the two lobes P3 and P4 of the second touch electrode 2 are substantially rounded. The two convex rounded corners P3 and P4 have a substantially semicircular shape. As shown in fig. 2A, all corners of the boundary of the second touch electrode 2 are rounded so that there is no sharp edge in the boundary.
Fig. 2D is a diagram showing the structure of a touch substrate corresponding to the region "B" in fig. 2A in some touch substrates. In fig. 2D, the four lobes C1, C2, C3, and C4 of the second touch electrode 2 are substantially rounded. The rounded corners C1, C2, C3 and C4 have a substantially quarter-round shape.
In some embodiments, substantially all corners of substantially all boundaries of the plurality of fill patterns are substantially rounded. Referring to fig. 2A and 2B, the filling pattern 3 of the touch substrate has two rounded corners P2 and P2'. The two lobes P2 and P2' have a substantially semicircular shape. As shown in fig. 2A, all corners of the boundary of the filling pattern 3 are rounded so that there is no sharp edge in the boundary.
Fig. 3A to 3B are diagrams illustrating structures of filling patterns in some embodiments. Referring to fig. 3A, the filling pattern 3 is a filling pattern corresponding to the filling pattern inside the region a in fig. 2A. As shown in fig. 2A and 3A, the filling pattern 3 is located between the first electrode 1 and the second electrode 2. In this embodiment, the filling pattern 3 is a complete filling pattern, all corners in its boundaries being rounded.
In some embodiments, the filler pattern may be a mosaic pattern including at least two sub-patterns to obtain a better blanking effect. Referring to fig. 3B, in some embodiments, the fill pattern includes six sub-patterns 3' insulated from each other and from adjacent first and second touch electrodes. All corners in the edges of all sub-patterns 3' are rounded.
In another aspect, the present disclosure provides a plurality of touch electrodes having continuously smoothly curved boundaries, e.g., substantially all of the boundaries of the plurality of touch electrodes are continuously smoothly curved. The touch electrode can be fabricated using a variety of suitable boundary shapes. Examples of suitable shapes include, but are not limited to, circular (including semicircle, quarter circle, etc.), sinusoidal, elliptical, parabolic, arcuate, and any combination thereof. For example, the touch electrode may have a substantially circular boundary (e.g., the boundary of the first touch electrode 1 in fig. 2A). The touch electrode may have a substantially arc-shaped boundary (e.g., the boundary of the second touch electrode 2 having four arcs in fig. 2A). Fig. 4A to 4C are diagrams illustrating touch electrode patterns in some embodiments. Referring to fig. 4A, the touch electrode may have a substantially four-leaf ornamental shape with all corners (including convex and concave corners) rounded. Referring to fig. 4B, the touch electrode may have a substantially trilobal shape with all corners (including lobes and valleys) rounded.

Examples of boundaries having a single continuous smooth curve include, but are not limited to, substantially circular boundaries, substantially elliptical boundaries, and substantially oval boundaries.

In some embodiments, the boundary of the touch electrode consists essentially of a plurality of continuous smooth curves connected adjacently by rounded corners (e.g., a plurality of rounded corners).

Referring to fig. 2A to 2C, the boundary of the first touch electrode 1 is substantially composed of eight arc curves adjacently connected by eight pairs of convex and concave circular angles P1 and R1. The boundary of the second touch electrode 2 is substantially composed of four arc-shaped curves adjacently connected by a convex rounded corner P3 and a convex rounded corner P4.
In some embodiments, substantially all corners of substantially all boundaries of the plurality of touch electrodes are substantially rounded and the boundaries of the touch electrodes may optionally include straight portions. Fig. 4D is a diagram illustrating a touch electrode pattern in some embodiments. Referring to fig. 4D, the boundary of the touch electrode in this embodiment is substantially composed of four straight line portions connected by four rounded corners (e.g., four semicircles shown in fig. 4D). Optionally, the straight portion is connected to the other portion of the boundary by a rounded corner.
In some embodiments, the straight portions transition smoothly to adjacent portions without rounded corners. For example, as long as the tangent line of the adjacent semicircle or quarter circle at the connection point substantially overlaps the straight line portion, the straight line portion may be smoothly connected to the adjacent semicircle or quarter circle without rounded corners. Referring to fig. 2D, the second touch electrode 2 in the region "B" has a boundary including a first arc-shaped curve connected to the first rounded corner C1, a second arc-shaped curve connected to the second rounded corner C3, and a short straight line portion connecting the first rounded corner C1 and the second rounded corner C3. The straight line portion between the first and second rounded corners C1 and C3 smoothly transitions to the adjacent first and second rounded corners C1 and C3 because tangent lines of the first and second rounded corners C1 and C3 overlap with the straight line portion at connection points thereof, respectively.
In some embodiments, the fill pattern or sub-pattern has continuously smoothly curved boundaries, e.g., substantially all of the boundaries of the fill pattern or sub-pattern thereof are continuously smoothly curved. The touch electrode can be fabricated using a variety of suitable boundary shapes. Examples of suitable shapes include, but are not limited to, circular (including semicircle, quarter circle, etc.), sinusoidal, elliptical, parabolic, arcuate, and any combination thereof.

Similarly, the boundary of each sub-pattern 3' in fig. 3B is substantially composed of two arc-shaped curves connected by two convex corners.
