Embodiment 1

[0046] see Figure 4 , as a modified design of the insulating member 13, the insulating member 23 provided is different from the insulating member 13 in that, compared with the traditional insulating member 13, the insulating member 23 is made of a material with a higher refractive index. Preferably, the refractive index of the insulating member 23 is greater than or equal to 1.67 and less than or equal to 1.85, so that the refractive index of the insulating member 23 is close to the refractive index of the patterned electrode layer 12 . It can be known from the principle of optics that the closer the refractive index of the two media is, the smaller the reflectivity is, and the greater the transmittance of light is. Therefore, by providing the insulating member 23 and the patterned electrode layer 12 with similar refractive indices, after the light enters the insulating member 23 and the patterned electrode layer 12, more light passes through the insulating member 23 and the ...

Embodiment 2

[0048] see Figure 5 with Image 6 , as another modified design of the insulating member 13, the insulating member 33 provided is different from the insulating member 13 in that the insulating member 33 is designed to have a smaller area. It is defined that the direction of the insulating member 33 on the X-axis is the direction of the width W of the insulating member 33 , and the direction of the insulating member 33 on the Y-axis is the direction of the length L of the insulating member 33 . Preferably, the length L of the insulating member 33 is less than 210 um, and the width W is less than 70 um. The structural design of the insulating member 33 with a smaller area makes it difficult for human eyes to distinguish the insulating member 33 , thereby effectively improving the visual effect of the touch panel 10 . Further, since the insulator 33 is provided with a smaller area, the contact area between the insulator 33 and the patterned electrode layer 12 is reduced, which i...

Embodiment 3

[0051] see Figure 7 , as another modified design of the insulating member 13, the insulating member 43 provided is different from the insulating member 13 in that the insulating member 43 with an appropriate chromaticity is used. Specifically, the chromaticity of the insulating member 43 is adjusted so that the chromaticity of the insulating member 43 is close to the chromaticity of the patterned electrode layer 12 . In this design, by controlling the chromaticity of the insulating member 43 so that it is consistent or substantially consistent with the chromaticity of the bridge 14 and the patterned electrode layer 12, it is not easy for human eyes to distinguish the insulating member 43 from the bridge 14 Therefore, the visual effect of the touch panel 10 can be effectively improved.

Abstract

The invention relates to a touch panel comprising a substrate and a patterned electrode layer arranged on the substrate, the patterned electrode layer includes a plurality of first direction electrodes and a plurality of second direction electrodes, the first direction electrodes and the second direction electrodes are staggered. The touch panel further includes a plurality of insulators disposedbetween the first direction electrodes and the second direction electrodes to electrically insulate the first direction electrodes and the second direction electrodes. The refractive index of the insulator is greater than or equal to 1.67 and less than or equal to 1.85. The touch panel provided by the invention has the insulators with a higher refractive index, so that the light reflectance of theinsulator is same or substantially same to that of the patterned electrode layer, so that the human eye is not easy to distinguish the insulators, and the visibility problem of the insulators is effectively improved.

Description

【Technical field】 [0001] The invention relates to the field of touch control, in particular to a touch panel. 【Background technique】 [0002] The touch sensing circuit of the current touch panel is generally manufactured by single-layer indium tin oxide (Single ITO, SITO) technology. Specifically, the X-axis sensing electrodes and the Y-axis conductive units in the touch sensing circuit are fabricated on a substrate, and are separated through another transparent conductive layer (such as indium tin oxide ITO). A bridge frame bridging the Y-axis is made, and the bridge is electrically connected to the conductive units in the Y-axis to form the Y-axis sensing electrodes. At the same time, the overlapping area between the traces and the X-axis sensing electrodes is electrically insulated from the X-axis and Y-axis sensing electrodes by arranging an insulator. [0003] However, when the insulating layer provided on the existing touch panel is not turned on, the human eyes can ...
