The touch layer 50 includes a plurality of sensing electrodes 51 , a plurality of sensing electrodes 52 , a plurality of ground electrodes 53 , and a plurality of slits 54 . The sensing electrode 51 includes a sensing area TX and a wire area W1. The wire area W1 is generally used to connect the signal source and the sensing area TX. Yu Ben In the embodiment, the ground electrode 53 grounds the electrode and its potential is zero; however, in other embodiments, the ground electrode may not be provided. In other embodiments, a dummy electrode (not shown) may be additionally disposed between the sensing electrodes 51, the sensing electrodes 52 or the ground electrodes 53. At this time, the dummy electrodes are not connected to any potential and the potential is not floating. fixed. The sensing electrode 51, the sensing electrode 52, and the grounding electrode 53 are spaced apart from each other via the slit 54. The slit 54 passes through electrode regions of different potentials, such as the sensing electrode 51, the sensing electrode 52, the grounding electrode 53, and two narrow electrodes. A sensing electrode, a sensing electrode, a grounding electrode or a portion of each of the electrodes is interposed between the slits 54. The sensing region TX of the sensing electrode 51 and the wire region W1, the sensing electrode 52, and the ground electrode 53 may be made of a transparent conductive material, such as indium tin oxide (ITO) or indium zinc oxide. , IZO). The wire region W1 of the sensing electrode 51 may also be composed of a metal material.

The sensing electrode 52 and the ground electrode 53 extend substantially in the longitudinal direction D2, and the longitudinal direction D2 is perpendicular to the lateral direction D1. The ground electrode 53 is located between the two sensing electrodes 52. In another embodiment, the ground electrode 53 may not be included, and the two adjacent sensing electrodes 52 in FIG. 3 are integrated into one sensing electrode 52.

The sensing regions TX are arranged substantially in the longitudinal direction D2 and are respectively adjacent to the sensing electrodes 52. The wire area W1 is connected to one corner of the sensing area TX and extends in the longitudinal direction D2. When the touch element A contacts the protective layer 80 and is located between the at least one sensing region TX and the sensing electrode 52, the sensing electrode 51 generates a driving signal.

In some embodiments, the area of the sensing region TX may be uniformly constant, smaller, or larger or a combination of the foregoing from top to bottom. In the present embodiment, as shown in FIG. 3, the area of the sensing area TX gradually decreases from the top to the bottom in the longitudinal direction D2. Wire area W1 Arranged along the lateral direction D1, and in the lateral direction D1, the number of the wire regions W1 is gradually increased from the top of the touch layer 50 as shown in FIG. 3 toward the bottom of the touch layer 50. The region where the wire region W1 and the slit 54 are alternately arranged forms the corrugated region Z1, but is not limited to the corrugated region Z1 drawn as shown in FIG.

Since the light transmittance of the slit 54 is different from the light transmittance of the sensing electrode 51, the sensing electrode 52, and the ground electrode 53, the slit 54 and the sensing electrode 51 and the sensing electrode are caused when the light penetrates the touch layer 50. The brightness of the ground electrode 53 is different, in particular, the corrugated area Z1 in which the wire area W1 and the slit 54 are densely arranged. When the light penetrates the corrugated area Z1, a line of light and dark staggered along the longitudinal direction D2 is formed.

In addition, since each of the pixels 131 is arranged in an array, when the light penetrates the touch layer 50 and the color filter layer 13, since the touch layer 50 and the color filter layer 13 are stacked on each other, the touch display panel 1 is The displayed picture may have a corrugated ripple pattern. When the ripple effect is strong, the screen displayed on the touch display panel 1 has a large probability of occurrence of a ripple pattern, and the ripple pattern is more obvious.

In the present embodiment, the wire region W1 and the slit 54 can be disposed in an appropriate manner to reduce the ripple effect. As shown in FIG. 3, the pixel 131 has a pixel pitch P1 in the lateral direction D1. In the third figure, a red, blue, and green three-color sub-pixel is used as an example.

The wire region W1 has a wire pitch P2 in the lateral direction D1, and the slit 54 has a slit width P3 in the lateral direction D1. The specified width P4 is defined as the wire width P2 of the wire region W1 plus the slit width P3 of the slit 54 in the adjacent wire region W1 and the slit 54. In other words, the adjacent wire region W1 and the slit 54 have fingers in the lateral direction D1. Set the width P4. A moire ratio is defined as (specified width P4 / pixel width P1) × 100%. The corrugation rate can be in accordance with the following formula (1): 25% + (50% × N) - a% ≦ ripple rate ≦ 25% + (50% × N) + a% formula (1)

In the above formula (1), N is 0 or a positive integer. In other embodiments, N can be between 0 and 8. The above a is an adjustment value, and a is between 0 and 20 or between 0 and 15. The range of the adjustment value a can be adjusted according to the allowable range of the process parameters.

For example, when N is 0 and a is 0, the ripple ratio is 25%. When the pixel width P1 is 100 um, the specified width P4 is 25 um. Therefore, when the wire region W1 in the corrugated region Z1 is set according to the ripple ratio of the formula (1), in the corrugated region Z1, the overlapping relationship between each pixel 131 and the wire region W1 is not completely the same in the lateral direction D1. , in turn, can reduce the ripple effect and reduce or dilute the ripple pattern. When N is 1 and a is 0, the ripple ratio is 75%. When N is 1 and a is 1, the waviness ratio is 74% or more and 76% or less.

When the wire region W1 is arranged and arranged within the range of the above-mentioned corrugation rate, the ripple effect can also be effectively reduced.

When the longitudinal distance Ly/lateral distance Lx satisfies the above range, the ripple effect in the corrugated area Z1 can also be effectively reduced.

An arrangement ratio is defined as (transverse distance Lx / pixel width P1) × 100% or (longitudinal distance Ly / pixel width P1) × 100%. The value of the arrangement ratio can satisfy the range of the following formula (2): 25% + (50% × N) - b% ≦ arrangement ratio ≦ 25% + (50% × N) + b% Formula (2)

The above N is 0 or a positive integer, and in other embodiments, the above N is between 0 and 8. The above b is an adjustment value, and the above b is between 0 and 20 or between 0 and 15. The range of the adjustment value b can be adjusted according to the allowable range of the process parameters.
