The touch layer 50 detects a touch event and generates a touch signal in accordance with the touch event, whereby the position of the touch is calculated and identified.

3 is a schematic view of a touch layer 50 according to a first embodiment of the present disclosure. The touch layer 50 includes a plurality of transfer electrodes 51, a plurality of sensing electrodes 52, a plurality of ground electrodes 53, and a plurality of slits 54. The transfer electrode 51 includes a transfer portion TX and a lead portion W1. The lead wire W1 is configured to connect a signal source (not shown in the figure) and a transfer unit TX.

In an embodiment, the ground electrode 53 is configured to ground the sense electrodes 52. The electric potential of the ground electrode 53 is substantially zero. In some embodiments, the ground electrodes 53 are excluded from the touch layer 50.

In some embodiments, the touch layer 50 further includes dummy electrodes (not shown in the figure) between the transfer electrodes 51 and the sense electrodes 52 (or the ground electrode 53) do. The dummy electrodes are not connected to any electrical potential, and the electrical potential of the dummy electrodes is fluid and not fixed.

The transfer electrode 51, the sensing electrode 52, and the ground electrode 53 are separated by the slits 54. The slits 54 pass through electrode regions having different electrical potentials, such as the transfer electrodes 51, the sensing electrodes 52, and the ground electrodes 53. The transfer electrode 51, the sensing electrode 52, and the ground electrode 53, or a portion of one of these electrodes, are between two adjacent slits 54.

The transfer portion TX of the transfer electrode 51 and the conductive portion W1, the sensing electrode 52 and the ground electrode 53 are formed of indium tin oxide (ITO) or indium zinc oxide (ITO). IZO). &Lt; / RTI &gt; The lead portion W1 of the transfer electrode 51 is formed of a metal material.

The plurality of transfer electrodes 51 are adjacent to the sensing electrode 52 and extend along the longitudinal direction D2. The sensing electrode 52 and the ground electrode 53 extend along the longitudinal direction D2. The longitudinal direction D2 is substantially perpendicular to the lateral direction D1. The ground electrode 53 is disposed between the two sensing electrodes 52. In another embodiment, the ground electrode 53 is excluded from the touch layer 50. The two adjacent sensing electrodes 52 in FIG. 3 are integrated into one.

The transfer parts TX are substantially arranged along the longitudinal direction D2 and are adjacent to the sensing electrode 52. [ The lead wire portion W1 is connected to a part of the transfer portion TX and extends along the longitudinal direction D2. When the touch element A1 contacts the protective layer 80 and is disposed on the transfer part TX and the sensing electrode 52, the transfer electrode 51 generates a driving signal.

In some embodiments, the area of the transmitters TX is the same along the longitudinal direction D2, or gradually decreases, or gradually increases. In the embodiment, as shown in FIG. 3, the area of the transmitters TX is gradually reduced along the longitudinal direction D2. The lead portions W1 are separated from each other and arranged along the lateral direction D1.

In the lateral direction D1, the number of lead portions W1 increases from one side of the touch layer 50 to the opposite side of the touch layer 50, as shown in Fig. The lead portions W1 and the slits 54 are alternately arranged in the moire region Z1, for example, as shown in Fig.

Since the light transmittance of the slits 54 is different from the light transmittance of the transfer electrodes 51, the sensing electrodes 52 and the ground electrodes 53, the brightness of the light rays passing through the slits 54, The brightness of the light rays passing through the electrodes 51, the sensing electrodes 52, and the ground electrodes 53 is different. Particularly, in the moire area Z1, the lead portions W1 and the slits 54 are densely arranged. It is shown that alternating light and dark lines extend along the longitudinal direction D2 when the light passes through the Moire zone Z1.

In addition, since the pixel regions 131 are arranged in an array, the image displayed on the touch display 1 has a moiré pattern due to the moiré effect when the touch layer 50 and the color filter layer 13 overlap each other . If the moiré effect is large, the change in moire pattern seen on the image generated by the touch display 1 is large.

In an embodiment, the lead portions W1 and the slits 54 are arranged in a suitable manner to reduce the Moire effect. As shown in FIG. 2, the pixel region 131 includes a pixel pitch P1 in the lateral direction D1. As shown in FIG. 2, in the embodiment, red, blue, and green subpixels 132 are disposed in the pixel region 131.

The slit 54 has a slit pitch P3 in the transverse direction D1. The predetermined pitch P4 is defined as the line pitch P2 of the lead portions W1 plus the slit pitch P3 of the slit 54. [ In other words, the lead portion of one of the lead portions W1 and the slit 54 adjacent thereto has a predetermined pitch P4 in the lateral direction D1. In one embodiment, the predetermined pitch P4 is defined as the width of one of the lead portions W1 plus the width of the slit 54 adjacent thereto.

The moire ratio is defined as (predetermined pitch (P4) / pixel pitch (P1)) X 100%. The moire ratio follows equation (1): &lt; EMI ID =

In the equation (1), N is 0 or a positive integer. In other embodiments, N is in the range of approximately 0 to 8. A is an adjustment value within the range of approximately 0 to 20, or 0 to 15. The range of adjustment values is adjusted according to the tolerance range of the parameters of the manufacturing process.

For example, when both N and A are 0, the moire ratio is 25%. When the pixel pitch P1 is 100 mu m, the predetermined pitch P4 is 25 mu m. Therefore, since the lead portions W1 in the moire region Z1 are designed in accordance with the moire ratios in the equation (1), in the moire region Z1, the pixel regions 131 and the lead portions W1 Each of the relative overlapping portions may be different in the transverse direction D1. Therefore, the moiré effect is lowered, and the moiré pattern is lowered or becomes faint. Also, for example, when N is 1 and A is 0, the moire ratio is 75%. When N is 1 and A is 1, the moire ratio is in the range of 74% to 76%.

When the lead portions W1 are designed and arranged in accordance with the range of the above-mentioned moire ratio, the moire effect of the touch display 1 is degraded.

As shown in Fig. 4, in the embodiment, the slit 54 is wave-shaped. The slit 54 includes a plurality of segments 541, 542. Segments 541 and 542 may be linear structures. The segments 541 may be substantially parallel to each other, and the segments 542 may be substantially parallel to each other. The segments 541 and 542 are arranged substantially orthogonally in the longitudinal direction D2.

The linear section W12 is connected to the inflection point W13 and the inflection point W14. The intersection W15 is disposed at the intersection of the extension of the inflection point W13 in the lateral direction D1 and the extension of the inflection point W14 in the longitudinal direction D2. The lateral distance Lx is defined as the distance between the inflection point W13 and the intersection W15 and the longitudinal distance Ly is defined as the distance between the inflection point W14 and the intersection W15.

The value of the longitudinal distance Ly / the lateral distance Lx is in the range of 0.33 to 3.05. In another embodiment, the value of the longitudinal distance Ly / lateral distance Lx is in the range of 0.4 to 2.50, or in the range of 0.45 to 2.15. When the value of the longitudinal distance Ly / the lateral distance Lx follows the above-described range, the moiré effect occurring in the moire area Z1 is degraded.

The arrangement ratio is defined as (lateral distance Lx / pixel pitch P1) X 100% or (longitudinal distance Ly / pixel pitch P1) X 100%. The value of the array ratio follows equation (2): &lt; RTI ID = 0.0 &gt;

N is 0 or a positive integer. In some embodiments, N is in the range of 0 to 8. B is an adjustment value in the range of 0 to 20, or 0 to 15. The range of the adjustment value (B) can be adjusted according to the tolerance range of the parameters of the manufacturing process. When the lead portions W1 are designed and arranged within the range of the Moire ratio, the Moire effect is degraded.

For example, when N is 1 and B is 0, the alignment ratio is approximately 75%. When N is 1 and B is 1, the alignment ratio is in the range of approximately 74% to 76%. For example, when the pixel pitch P1 is approximately 100 占 퐉, the lateral distance Lx or the longitudinal distance Ly is in the range of approximately 74 占 퐉 to approximately 76 占 퐉.

The moire ratio corresponding to the first zone Z11 follows the equation (1), and the moire ratio corresponding to the second zone Z12 follows the equation (3). Therefore, the predetermined pitches in the moire zone Z1 can be different. In an embodiment, the predetermined pitch P4 of the first zone Z11 is less than the predetermined pitch P5 of the second zone Z12. When the lead portions W1 in the first zone Z11 and the second zone Z12 are designed according to the equation (3), the moire effect of the moire zone Z1 is lowered.
