Description

Touch display

The present disclosure relates to a display, and more particularly to a touch display having a touch function.

Due to the advantages of thin size, light weight and low radiation, liquid crystal displays have gradually become the mainstream of the market. Most current displays have touch functions. However, as the size of the display is larger, the signal transmission line inside the display becomes longer. Since the transmission line has a large equivalent impedance, it affects the correctness of the signal on the transmission line.

The present disclosure provides a touch display including a first substrate, a second substrate, and a display medium layer. The display medium layer is disposed between the first and second substrates. The first substrate includes a plurality of pixel units, a first touch electrode, and a plurality of first connecting lines. The pixel units are arranged in an array. The first touch electrode corresponds to at least one pixel unit. Each of the first connecting lines extends in a first direction and is coupled between the first touch electrodes and a touch integrated circuit.

FIG. 1 is a cross-sectional view of a touch display of the present disclosure.

2, 3, 4A~4D, 5A, 5B, and 6-8 are schematic diagrams of the touch element layer of the present disclosure.

FIG. 1 is a possible cross-sectional view of the touch display of the present disclosure. As shown, the touch display 100 includes at least a first substrate 110, a display device layer 120, a touch device layer 130, a display dielectric layer 140, and a second substrate 150. The display element layer 120 is formed over the first substrate 110. In one possible embodiment, display element layer 120 has at least one metal layer (not shown) for forming complex pixel elements 121. The pixel units 121 may be arranged in an array, but are not intended to limit the disclosure. In other embodiments, the pixel units 121 may be arranged in a delta manner.

The touch element layer 130 is disposed on the display element layer 120, but is not intended to limit the disclosure. In other possible embodiments, the touch element layer 130 is disposed between the display element layer 120 and the first substrate 110. When the touch element layer 130 is disposed on the display element layer 120, the arrangement relationship between the display element layer 120 and the touch element layer 130 is referred to as an upper top com architecture. When the display device layer 120 is disposed on the touch device layer 130, the arrangement relationship between the display device layer 120 and the touch device layer 130 is referred to as a top pixel structure.

The touch element layer 130 may have at least one metal layer for forming a plurality of touch electrodes SC and a connection line ML connecting the touch electrodes SC. In a touch detection mode, the touch electrode SC receives the detection signal provided by a touch integrated circuit 131 through the connection line ML. The touch integrated circuit 131 detects the electrical change of the touch electrode SC through the connection line ML to determine whether the user touches the touch display 100. in In a display mode, the touch integrated circuit 131 does not control the voltage level of the touch electrode SC. At this time, the touch electrode SC receives a common voltage and acts as a common electrode.

The display medium layer 140 is disposed between the touch element layer 130 and the second substrate 150. The display medium on which the dielectric layer 140 is displayed may be a liquid crystal or an organic light emitting diode. In this embodiment, since the touch element layer 130 is disposed between the display medium layer 140 and the first substrate 110, the touch display 100 is an in-cell architecture.

The second substrate 150 has a color filter layer 151. The color filter layer 151 has a plurality of color filters for allowing light of a specific color to pass. In a possible embodiment, each color filter element corresponds to a pixel unit 121. In another possible embodiment, the second substrate 150 may also have no color filter layer 151. In another possible embodiment, the first substrate 110 has a color filter layer 151.

FIG. 2 is a possible schematic diagram of the touch element layer 130 of the present disclosure. The touch device layer 130 includes at least a plurality of touch electrodes and a touch integrated circuit. For convenience of description, FIG. 2 only shows the touch electrodes SC 1 to SC 9 , but is not intended to limit the disclosure. In other embodiments, the touch element layer 130 has other numbers of touch electrodes. Each touch electrode corresponds to at least one pixel unit 121. The present invention does not limit the arrangement of the touch electrodes SC 1 to SC 9 . In a possible embodiment, the touch electrodes SC 1 -SC 9 are arranged in an array.

The touch electrodes SC 1 to SC 9 are coupled to the contact control body circuit 210 via the connection lines ML 11 to ML 28 , and the connection lines ML 11 to ML 28 extend in a first direction D1 . In a touch detection mode, the touch integrated circuit 210 provides detection signals to the touch electrodes SC 1 to SC 9 through the connection lines ML 11 to ML 28 , and detects the power of the touch electrodes SC 1 to SC 9 . Sexual change to determine where the touch is. In a display mode, the touch integrated circuit 210 does not control the voltage levels of the touch electrodes SC 1 -SC 9 . In this mode, the touch electrodes SC 1 to SC 9 function as a common electrode and receive a common voltage.

In this embodiment, since the connection lines ML 11 to ML 28 are independent, the touch integrated circuit 210 can provide different detection signals to the same touch electrode. For example, the touch integrated circuit 210 through a first connection line ML 13 provides signal to detect the touch electrode SC 1, and provides a second detection signal through connection lines ML 14 to touch electrode SC 1. The first detection signal may be the same or different from the second detection signal. In this example, since the touch integrated circuit 210 provides two detection signals to the touch electrodes SC 1 through the independent connection lines ML 13 and ML 14 , the voltage levels of different regions of the touch electrodes SC 1 can be controlled.

In this embodiment, each touch electrode is coupled to the control integrated circuit 210 through a plurality of connection lines. For example, the touch electrode SC 1 is coupled to the ML 14 via the connection line ML 13 and the contact control body circuit 210; the touch electrode SC 4 is coupled to the ML 15 via the connection line ML 12 and the contact control body circuit 210; the touch electrode SC 7 is coupled to the control integrated circuit 210 via the connection line ML 11 and the ML 16 . The invention does not limit the number of connecting lines to which each touch electrode is coupled. In some embodiments, at least one of the touch electrodes SC 1 -SC 9 is coupled to two or more connection lines.

In addition, in this embodiment, each touch electrode is coupled to two connecting lines, but is not intended to limit the present invention. In other embodiments, the number of connection lines to which at least one of the touch electrodes SC 1 -SC 9 is coupled is different from the number of connection lines to which the other of the touch electrodes SC 1 -SC 9 is coupled. For example, the touch electrode SC 1 may be coupled to three connection lines, and the touch electrode SC 4 is coupled to two connection lines.

In this embodiment, each of the touch electrodes SC 1 -SC 9 is coupled to the corresponding connecting line through the five through holes, but is not intended to limit the present invention. In one embodiment, the number of through holes to which at least one of the touch electrodes SC 1 to SC 9 is coupled is different from the number of through holes to which the other of the touch electrodes SC 1 to SC 9 is coupled. In another possible embodiment, each of the touch electrodes SC 1 -SC 9 is coupled to the corresponding connection line through another number of through holes.

Each touch electrode is electrically coupled to the two connecting lines. In this embodiment, the connection line that is closer to the left side boundary of the touch electrode is referred to as the left side connection line, and the connection line that is closer to the right side boundary of the touch electrode is referred to as the right side connection line. For example, the touch electrodes SC 1 connected to the coupled line ML 13 closer to the left border of the touch electrodes SC 1 LE 1, it is called the left side of the connection line. Similarly, the touch electrodes SC 1 connected to the coupled line ML 14 closer to the right edge of the touch electrodes SC 1 1 REs, it is known as the right cable.

The distance between the left connecting line in each touch electrode and the corresponding left side boundary is called the left side distance. The distance between the right connecting line and the right border of the corresponding touch electrode is called the right side distance. For example, the distance LD 21 between the left connecting line ML 13 and the left side border LE 1 in the touch electrode SC 1 in a second direction D2 is referred to as a left side distance. In a possible embodiment, the second direction D2 is substantially perpendicular to the first direction D1. The distance RD 21 between the right connecting line ML 14 and the right side border RE 1 in the second direction D2 is referred to as the right side distance.

For the same touch electrode, the left distance may or may not be equal to the right distance. Taking the touch electrode SC 1 as an example, the left side distance LD 21 is equal to the right side distance RD 21 , but is not intended to limit the present invention. In another possible embodiment, the left side distance LD 21 is smaller or larger than the right side distance RD 21 . In other embodiments, at least one of the left side distances LD 21 LD LD 29 may be equal to or not equal to the other of the left side distances LD 21 LD LD 29 . Likewise, at least one of the right side distances RD 21 ~ RD 29 may or may not be equal to the other of the right side distances RD 21 ~ RD 29 .

In the present embodiment, the left side of the touch electrodes SC 1 2 22 a distance equal to the right side of the touch electrodes SC from the RD LD 21, from the right side of the touch electrodes 2 is equal to the touch electrode 22 the RD SC SC 3 left distance LD 23. Similarly, the left side of the touch electrodes SC 5 LD 25 is equal to a distance from the right side of the touch electrode 4 SC RD 24, the right side of the touch electrodes SC from 5 to RD 25 from the LD 26 is equal to the left side of the touch electrodes SC. 6. The touch electrodes SC. 8 left a distance equal to the LD 28 of the touch electrodes SC from the right side 7 RD 27, right side 28 of the touch electrodes SC. 8 left touch electrodes SC. 9 equal distance from the LD 29 RD. In this example, the left side distance LD 22 of the touch electrode SC 2 may or may not be equal to the right side distance RD 22 . Likewise, the left side distance LD 25 of the touch electrode SC 5 may or may not be equal to the right side distance RD 25 . The left side distance LD 28 of the touch electrode SC 8 may or may not be equal to the right side distance RD 28 .

FIG. 3 is a schematic view showing another relationship between the connecting line and the touch electrode of the present invention. As shown in the figure, the left side distance LD 34 of the touch electrode SC 4 is larger than the left side distance LD 31 of the touch electrode SC 1 and smaller than the left side distance LD 37 of the touch electrode SC 7 . In addition, the right side distance RD 34 of the touch electrode SC 4 is larger than the right side distance RD 31 of the touch electrode SC 1 and smaller than the right side distance RD 37 of the touch electrode SC 7 .

In the present embodiment, the left side of the touch electrode SC 2 SC 32 is equal to the right side of the touch electrodes SC. 1 is equal to the touch electrode 32 from the distance RD 31, RD right touch electrode SC 2 of the 3 left a distance from the LD 33 LD. Similarly, the left side of the touch electrodes SC 5 is equal to the right side of the touch electrode 35 is equal to the left. 4 SC SC. 6 touch electrode distance 34 from the LD 36, the right side of the touch electrodes SC RD RD 5 a distance 35 from the LD. SC. 8 left touch electrode 38 is equal to the right side of the touch electrodes SC distance 7 distance LD 39 RD 37, right side 38 of the touch electrodes SC. 8 left touch electrodes SC. 9 equal distance RD distance LD.

4A to 4D are schematic diagrams showing other relationships between the connection line and the touch electrode of the present invention. In FIGS. 4A-4D, there is an intermediate connection line between the left connection line and the right connection line in each touch electrode. Taking the touch electrode SC 1 of FIG. 4A as an example, the left connection line ML 41 and the right connection line ML 49 have an intermediate connection line ML 46 .

The invention does not limit the distance between the intermediate connecting line to the corresponding right connecting line and the left connecting line. Taking the touch electrode SC 1 of FIG. 4A as an example, the intermediate distance MD 1 between the intermediate connection line ML 46 and the left connection line ML 41 in the second direction D2 may be equal to, greater than, or smaller than the intermediate connection line ML 46 to the right. The intermediate distance MD 2 between the connecting lines ML 49 in the second direction D2.

FIG. 5A is another possible schematic diagram of the touch element layer of the present disclosure. In this embodiment, each touch electrode is coupled to a plurality of connection lines, but only one connection line is directly coupled to the contact control body circuit 510. Taking the touch electrode SC 1 as an example, the touch electrode SC 1 is electrically connected to the connection lines ML 51 ML ML 53 , but only the connection line ML 51 is directly coupled to the contact control body circuit 510 . The connection lines ML 52 to ML 53 are not directly coupled to the contact control body circuit 510. In this example, the connection lines ML 52 to ML 53 are electrically connected to the connection line ML 51 through the sub-wires SL 11 to SL 17 .

In FIG. 5A, each touch electrode is coupled to a connecting line through a consistent hole. For example, the touch electrode SC 1 is electrically connected to the connection lines ML 51 to ML 53 through the through holes V 1 to V 3 ; the touch electrode SC 4 is electrically connected to the connection lines ML 54 to ML through the through holes V 4 to V 5 . 55 ; the touch electrode SC 7 is electrically connected to the connection line ML 56 through the through hole V 6 . The disclosure does not limit the number and location of the connecting lines and the through holes to which each touch electrode is connected. In this embodiment, the number of connecting lines connected to the touch electrode SC 1 is different from the connecting line and the through hole of the touch electrodes (such as SC 4 and SC 7 ) that are different from the same row (vertical direction). Quantity, but not intended to limit the disclosure. In other embodiments, for the touch electrodes of the same row, the number of connecting lines and through holes connected to one touch electrode may be the same as the number of connecting lines and through holes connected to the other touch electrodes.

In addition, in this embodiment, the number of connection lines to which the touch electrodes of each column (horizontal direction) are connected is the same. For example, the touch electrodes SC 1 -SC 3 are all coupled to three connecting lines, but are not intended to limit the disclosure. In other embodiments, in the touch electrodes of the same column, the number of connecting lines connected to one touch electrode may be the same or different from the number of connecting lines connected to the other touch electrodes.

For convenience of explanation, FIG. 5A only shows the connection lines ML 51 to ML 68 . As shown, the connecting lines ML 51 to ML 68 are arranged in parallel with each other and extend in the first direction D1 (vertical direction). In the present embodiment, the connecting lines ML 51 ML ML 68 extend in a straight line, but are not intended to limit the disclosure. In other embodiments, as shown in FIG. 5B, the connecting lines ML 71 to ML 88 extend in a zigzag manner.

Returning to FIG. 5A, when the connecting lines ML 51 ML ML 68 extend in the first direction D1, each connecting line overlaps at least one touch electrode. For example, the line segments 211a to 211c of the connection lines ML 51 to ML 53 overlap the touch electrode SC 1 ; the line segments 212a to 212c of the connection lines ML 51 to ML 53 overlap the touch electrode SC 4 ; the connection line ML 51 ~ ML The line segments 213a to 213c of 53 overlap the touch electrode SC 7 .

In a possible embodiment, the connecting lines ML 51 ML ML 68 extend to the upper boundary TE 1 of the touch electrode SC 1 in the first direction D1. In addition, the connection lines ML 54 ML 55 may extend to the upper boundary TE 4 of the touch electrode SC 4 in the first direction D1. In this example, the connection lines ML 54 ML 55 may extend to the upper boundary TE 1 of the touch electrode SC 1 in the first direction D1. Therefore, the connection lines ML 54 ML 55 overlap the touch electrode SC 1 , but It is electrically connected to the touch electrode SC 1 . Similarly, the connection line ML 56 may extend to the upper boundary TE 7 of the touch electrode SC 7 in the first direction D1, or may extend to the upper boundary TE 4 of the touch electrode SC 4 or extend to the touch electrode. The upper boundary of SC 1 is TE 1 . In this example, the connection lines ML 56 may overlap the touch electrodes SC 1 and SC 4 but are not electrically connected to the touch electrodes SC 1 and SC 4 .

In this embodiment, the widths of all the line segments are the same for the same connecting line. For example, the width of the line segment 211a ~ 213 a are the same, but not to limit the present disclosure. In other embodiments, the width of all line segments is not exactly the same for the same connection line. Referring to FIG. 7, for the connection line ML 81 , the widths of the line segments 401 to 403 are different. As shown, the width of line segment 401 is greater than line segments 402 and 403, and the width of line segment 402 is again greater than line segment 403. In a possible embodiment, the width of the line segment farther away from the touch integrated circuit 510 is larger, but is not intended to limit the disclosure. In other embodiments, at least one of the plurality of line segments in the same connection line may have the same width as the other line segment.

In addition, for a plurality of connecting lines connected to the same touch electrode, the width of one of the connecting lines may be the same or different from the width of the other. Referring to FIG. 7, for the connection lines ML 81 ML ML 83 to which the touch electrodes SC 1 are connected, the width of the connection lines ML 81 may be different from the widths of the connection lines ML 82 and ML 83 . In Fig. 7, the connecting lines ML 82 and ML 83 have the same width, but are not intended to limit the disclosure. In other embodiments, the widths of the plurality of connecting lines connected to the same touch electrode are different.

In other embodiments, the width of the connection line to which one touch electrode is connected may be different from the width of the connection line to which the other touch electrode is connected. Referring to FIG. 7, the width of the connection line ML 81 to which the touch electrode SC 1 is connected is different from the width of the connection line ML 84 to which the touch electrode SC 4 is connected. In FIG. 7 , although the width of the connection line ML 81 to which the touch electrode SC 1 is connected is the same as the width of the connection line ML 87 to which the touch electrode SC 2 is connected, it is not intended to limit the disclosure. In other embodiments, for the touch electrodes in the same column, the width of one connection line connected to one touch electrode may be the same or different from the width of one connection line to which another touch electrode is connected. In addition, in FIG. 8, the width of the connection line ML 91 to which the touch electrode SC 1 is connected remains unchanged, but unlike the width of the connection line ML 92 to which the touch electrode SC 4 is connected, the connection is farther away from the touch product. The wider the width of the connection line of the touch electrode of the body circuit 510, but it is not intended to limit the disclosure.

Returning to FIG. 5A, the secondary wires SL 11 to SL 43 are arranged in parallel with each other and extend in the second direction D2 (horizontal direction). In a possible embodiment, the second direction D2 is substantially perpendicular to the first direction D1. Each wire is coupled to at least two adjacent connecting wires. For example, the secondary wire SL 22 is coupled to the connecting wires ML 57 ML ML 59 , but is not intended to limit the disclosure.
