  FIG. 2 is a schematic diagram illustrating a display zone of the display panel 10 according to the present disclosure. As shown in FIG. 2, the display zone includes a plurality of pixel regions 131. Pixel regions 131 are arranged in an array. Each pixel region 131 includes a plurality of subpixels 132 (subpixels). The sub-pixels 132 in the pixel region 131 correspond to color filters having different colors in the color filter layer 13. After the light beam passes through sub-pixels 132 corresponding to different color filters, the light beam line appears different colors.

  For example, if the pixel region 131 of the display panel 10 includes a red subpixel 132a, a green subpixel 132b, and a blue subpixel 132c, the red subpixel 132a corresponds to a red color filter and the green subpixel 132b is green.

The red sub-pixel 132a, the green sub-pixel 132b, and the blue sub-pixel 132c are repeatedly installed in order in the horizontal direction D1, or are arranged by other appropriate designs.

  When a light beam such as white light emitted by a backlight unit (not shown) passes through the red subpixel 132a, the light beam turns red. When white light passes through the green subpixel 132b, the white light turns green. When the white light passes through the blue subpixel 132c, the white light turns blue. In some embodiments, the pixel region 131 of the display panel 10 includes red, blue, green, and white subpixels, or red, blue, green, and yellow subpixels.

  The second substrate 14 is made of a transparent material such as glass. In some embodiments, the second substrate 14 is a transparent flexible substrate. The second substrate 14 is disposed on the display media layer 12. The second substrate 14 is disposed on the color filter layer 13.

  The touch layer 50 generates a touch signal according to the touch event. For example, the touch event is caused by the touch element A1 touching the protective layer 80. In some embodiments, the touch element A1 is a finger or a touch pen. The touch layer 50 is disposed on the second substrate 14 and below the protective layer 80. The touch layer 50 is disposed on the first substrate 11 or between the first substrate 11 and the second substrate 14. In other embodiments, the touch layer 50 is disposed between the color filter layer 13 and the display media layer 12.

  The first polarizing layer 60 is disposed under the first substrate 11, and the second polarizing layer 70 is disposed on the touch layer 50. The first polarizing layer 60 and the second polarizing layer 70 are configured to polarize the light beam that passes through the first polarizing layer 60 and the second polarizing layer 70. In other words, the display medium layer 12, the color filter layer 13, the second substrate 14, the thin film transistor layer 15, the touch layer 50, and the second polarizing layer 70 are disposed between the first substrate 11 and the protective layer 80. The

  The protective layer 80 is made of a transparent material such as glass, and protects the elements inside the touch display 1. In another embodiment, the second polarizing layer 70 functions as a protective layer because the second polarizing layer 70 has a function such as a scratch prevention function or a dirt prevention function. When the touch element A1 touches the protective layer 80 or the second polarizing layer 70, a touch event is triggered. The touch layer 50 detects touch events and generates touch signals according to the touch events, so that the location of the touch is calculated and identified.

  FIG. 3 is a schematic diagram of a touch layer 50 according to a first embodiment of the present disclosure. The touch layer 50 includes a plurality of transmission electrodes 51, a plurality of detection electrodes 52, a plurality of ground electrodes 53, and a plurality of slits 54. The transmission electrode 51 includes a transmission portion TX and a conductive wire portion W1. The conducting wire portion W1 is configured to connect a signal source (not shown) and the transmitting portion TX.

  In that embodiment, the ground electrode 53 is configured to ground the detection electrode 52. The potential of the ground electrode 53 is about zero. In some embodiments, the ground electrode 53 is excluded from the touch layer 50.

  In some embodiments, the touch layer 50 further includes a dummy electrode (not shown) between the transmission electrode 51 and the detection electrode 52 (or the ground electrode 53). The dummy electrode is not connected to any potential, and the potential of the dummy electrode is floated and not fixed.

  The transmission electrode 51, the detection electrode 52, and the ground electrode 53 are separated by a slit 54. The slit 54 passes through electrode zones having different potentials, such as the transmission electrode 51, the detection electrode 52, and the ground electrode 53. The transmission electrode 51, the detection electrode 52, the ground electrode 53, or a part of each of the above-described electrodes is located between two adjacent slits 54.

  The transmission portion TX and the conductive wire portion W1, the detection electrode 52, and the ground electrode 53 of the transmission electrode 51 are made of a transparent conductive material such as indium tin oxide (ITO) or indium zinc oxide (IZO). The conductive wire portion W1 of the transmission electrode 51 is made of a metal material.

  A plurality of transmission electrodes 51 are adjacent to the detection electrode 52 and extend in the vertical direction D2. The detection electrode 52 and the ground electrode 53 extend in the vertical direction D2. The vertical direction D2 is substantially perpendicular to the horizontal direction D1. The ground electrode 53 is disposed between the two detection electrodes 52. In other embodiments, the ground electrode 53 is excluded from the touch layer 50. Two adjacent detection electrodes 52 in FIG. 3 are integrated into one.

  The transmission portion TX is substantially disposed along the longitudinal direction D2 adjacent to the detection electrode 52. The conductor portion W1 is connected to a part of the transmission portion TX and extends along the vertical direction D2. When the touch element A1 touches the protective layer 80 or the second polarizing layer 70 and is positioned on the transmission portion TX and the detection electrode 52, the transmission electrode 51 generates a drive signal.

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

  As shown in FIG. 3, in the lateral direction D <b> 1, the number of conductive wire portions W <b> 1 increases from one side of the touch layer 50 to the opposite side of the touch layer 50. As shown in FIG. 3, for example, the conductive wire portions W1 and the slits 54 are alternately arranged in the moire zone Z1.

  Since the transmittance of the slit 54 is different from the transmittance of the transmission electrode 51, the detection electrode 52, and the ground electrode 53, the luminance of the light beam that passes through the slit 54 Different from the brightness of the light beam that passes through. In particular, in the moire zone Z1, the conductor portion W1 and the slits 54 are arranged with high density. As the light beam passes through the moire zone Z1, alternating bright and shade lines extending along the longitudinal direction D2 are shown.

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

  In that embodiment, the conductor portion W1 and the slit 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 horizontal direction D1. As shown in FIG. 2, in that embodiment, the red, blue, and green subpixels 132 are disposed in the pixel region 131. In other embodiments, the red, green, blue, and yellow sub-pixels 132 are disposed in the pixel region 131.

  FIG. 4 shows a moiré zone Z1 of the touch layer 50 according to the first embodiment of the present disclosure. The conductor portion W1 has a wire pitch P2 in the lateral direction D1. The slit 54 has a slit pitch P3 in the lateral direction D1. The predetermined pitch P4 is determined as a value obtained by adding the slit pitch P3 of the slit 54 to the wire pitch P2 of the conductor portion W1. In other words, one of the conductive wire portions W1 and the adjacent slit 54 have a predetermined pitch P4 in the lateral direction D1. In one embodiment, the predetermined pitch P4 is defined as one width of the conductor portion W1 plus the width of the adjacent slit 54.

The moire ratio is determined as (predetermined pitch P4 / pixel pitch P1) × 100%. Moire ratio follows the following formula (1):

Formula (1): 25% + (50% × N) −A% ≦ Moire ratio ≦ 25% + (50% × N) + A%

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

  For example, when both N and A are 0, the moire ratio is 25%. When the pixel pitch P1 is 100 μm, the predetermined pitch P4 is 25 μm. Accordingly, since the conductor portion W1 in the moiré zone Z1 is designed according to the moiré ratio of the formula (1), each of the relative overlap positions of the pixel region 131 and the conductor portion W1 in the moiré zone Z1 is the horizontal direction D1. May vary. Therefore, the moire effect is reduced and the moire pattern is reduced or less noticeable. Moreover, 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 74% to 76%.

  When the conductor portion W1 is designed and arranged according to the above-described range of the moire ratio, the moire effect of the touch display 1 is reduced.

  As shown in FIG. 4, in the embodiment, the slit 54 has a waveform. The slit 54 includes a plurality of segments 541 and 542. Segments 541 and 542 may be linear structures. Segments 541 can be substantially parallel to each other and segments 542 can be substantially parallel to each other. The segments 541 and 542 are alternately arranged substantially in the longitudinal direction D2. The segment 541 extends along the first extending direction D3, and the segment 542 extends along the second extending direction D4.

  The conducting wire portion W1 is a conductive layer. The conductive layer is made of a transparent conductive material or metal. The conducting wire portion W1 is disposed between two adjacent slits 54, and the conducting wire portion W1 has a corrugated structure. The moire effect of the touch display 1 is reduced by the corrugated slit 54 and the conductor portion W1.

  The conducting wire portion W1 includes a plurality of linear sections W11 and a plurality of linear sections W12. The linear sections W11 and W12 can be linear structures. The linear sections W11 are substantially parallel to each other, and the linear sections W12 are substantially parallel to each other. The linear sections W11 and W12 are arranged alternately in the longitudinal direction D2. The linear section W11 extends substantially along the first extending direction D3, and the linear section W12 extends substantially along the second extending direction D4. The first acute angle is between the first stretching direction D3 and the longitudinal direction D2. The second acute angle is between the second stretching direction D4 and the longitudinal direction D2. The first acute angle may be the same as or different from the second acute angle.

  An inflection point W13 and an inflection point W14 are disposed at the two ends of the edge of the linear section W11. The linear section W12 is connected to the inflection point W13 and the inflection point W14. The intersection point W15 is disposed at the intersection of the extension of the inflection point W13 in the horizontal direction D1 and the extension of the inflection point W14 in the vertical 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 / lateral distance Lx is in the range of 0.33 to 3.05. In other embodiments, the value of the longitudinal distance Ly / lateral distance Lx is in the range of 0.4 to 2.50 or 0.45 to 2.15. When the value of the vertical distance Ly / the horizontal distance Lx follows the above-described width, the moire effect generated in the moire zone Z1 is reduced.

The arrangement ratio is determined as (lateral distance Lx / pixel pitch P1) × 100% or (vertical distance Ly / pixel pitch P1) × 100%. Sequence ratio values follow the following formula (2):

Formula (2): 25% + (50% × N) −B% ≦ sequence ratio ≦ 25% + (50% × N) + B%

  In the formula (2), N is 0 or a positive integer. In some embodiments, N is in the range of 0-8. B is an adjustment value in the range of 0-20 or 0-15. The width of the adjustment value B can be adjusted according to the tolerance range of the manufacturing process parameters. When the conductor portion W1 is designed and arranged within the range of the moire ratio, the moire effect is reduced.

  For example, when N is 1 and B is 0, the sequence ratio is about 75%. When N is 1 and B is 1, the sequence ratio is in the range of about 74% to 76%. For example, when the pixel pitch P1 is about 100 μm, the horizontal distance Lx or the vertical distance Ly is in the range of about 74 μm to 76 μm.

  FIG. 5 is a schematic diagram of the moiré zone Z1 of the touch layer 50 according to the second embodiment of the present disclosure. The moire zone Z1 further includes a first zone Z11 and a second zone Z12 adjacent to the first zone Z11. In some embodiments, the moire zone Z1 includes at least three zones.

The first zone Z11 and the second zone Z12 are arranged along the lateral direction D1. The arrangement of the conductor portion W1 in the first zone Z11 is designed according to the formula (1). The arrangement of the conductor part W1 in the second zone Z12 is designed according to the following formula (3):

Formula (3): 25% + (50% × (N + 1) ) − A% ≦ Moire ratio ≦ 25% + (50% × (N + 1)) + A%

  In the formula (3), N is 0 or a positive integer. In some embodiments, N is in the range of 0-8. A is an adjustment value. The range of the adjustment value A can be adjusted according to the tolerance range of the manufacturing process parameters. A is in the range of 0-20 or 0-15. The moire ratio corresponding to the first zone Z11 follows formula (1), and the moire ratio corresponding to the second zone Z12 follows formula (3). Therefore, the predetermined pitch in the moire zone Z1 can be different. In the embodiment, the predetermined pitch P4 of the first zone Z11 is smaller than the predetermined pitch P5 of the second zone Z12. When the conductor portion W1 in the first zone Z11 and the second zone Z12 is designed according to the formula (3), the moire effect of the moire zone Z1 is reduced.

  FIG. 6 is a schematic diagram of a touch layer 50 according to a second embodiment of the present disclosure. In that embodiment, a plurality of dummy slits may be disposed in the transmission portion TX, the detection electrode 52, and the ground electrode 53 in order to further reduce the moire effect. One of the electrodes E2 is disposed between two adjacent dummy slits E1.

  The dummy slit E1 has a corrugated structure extending along the vertical direction D2. In the embodiment, the shape of the dummy slit E <b> 1 corresponds to the shape of the slit 54. However, in some embodiments, the shape of the dummy slit E1 may not correspond to the shape of the slit 54. The dummy slits can have different shapes according to the design specifications of the touch display 1. In that embodiment, the two ends of the dummy slit E1 are not connected to the slit 54 at the same time. In other words, the dummy slit E1 is distributed to one electrode zone having the same potential. In other words, the electrodes around the dummy slit E1 have the same potential. For the arrangement of a part of the dummy slit E1, the arrangement of the slit 54 can be referred to.

  One of the electrodes E2 is disposed between the slit 54 and the adjacent dummy slit E1. The electrode E2 has a corrugated structure extending along the vertical direction D2. The design of the electrode E2 can refer to the conductor portion W1. The electrode E2 may be a part of the conductive wire portion W1 and the transmission portion TX of the transmission electrode 51. The electrode E2 can be part of the detection electrode 52, the ground electrode 53, or a dummy electrode.

  FIG. 7 is a schematic diagram showing a moire thorn Z2 of the touch layer 50 according to the third embodiment of the present invention. As shown in FIG. 7, the dummy slit E1 and the electrode E2 are in the moire zone Z2. Each dummy slit and its adjacent electrode E2 have a predetermined dummy pitch P6 in the lateral direction D1. In other words, the predetermined pitch P6 of the dummy in the lateral direction D1 is determined as one width of the dummy slit plus the width of the adjacent electrode E2. The moire ratio is determined as (dummy predetermined pitch P6 / pixel pitch P1) × 100%. Therefore, in that embodiment, the dummy predetermined pitch P6 corresponding to the electrode E2 corresponds to the predetermined pitch P4 determined according to the formula (1). In other words, the moire ratio follows formula (1).

  The value of the longitudinal distance Ey / lateral distance Ex of the electrode E2 is in the range of 0.33 to 3.05. In other embodiments, the value of longitudinal distance Ey / lateral distance Ex is in the range of 0.4 to 2.50 or 0.45 to 2.15.
