Description

Technical Field

[0001] This utility model relates to the field of displays, and in particular to an ITO component that reduces bridge point shadows. Background Technology

[0002] As living standards improve, consumers are becoming increasingly demanding in terms of product performance and appearance. In TP (transfer permeable) production, the visibility of the background pattern is a major concern. In conventional ITO cross-linking structures, the transmittance of ITO with different film thicknesses is around 80-87%, while that of OC (octane permeable) is generally around 97-98%. Because there is an additional layer of ITO pattern at the cross-linking locations compared to other areas, the pattern marks at the cross-linking points become more noticeable to the naked eye.

[0022] An ITO component 100 for reducing bridge point shadows, comprising a carrier sheet 10, a first ITO layer 11, a first insulating film 12, a second ITO layer 13, a metal trace layer 14, a second insulating film 15, and an interface 20. Detailed Implementation

[0023] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0024] This application proposes an ITO component 100 for reducing bridge point shadows; please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 The assembly comprises: a carrier sheet 10, a first ITO layer 11, a first separator film 12, a second ITO layer 13, a metal trace layer 14, and a second separator film 15, stacked sequentially. The carrier sheet 10 is transparent with good light transmittance. The first ITO layer 11 and the second ITO layer 13 are bonded to both sides of the first separator film 12, which isolates the first ITO layer 11 and the second ITO layer 13, preventing them from being electrically connected and thus avoiding short circuits. The first ITO layer 11 is conductive in a first direction, and the second ITO layer 13 is conductive in a second direction, with the first and second directions perpendicular to each other. In this application, the first ITO layer 11 and the second ITO layer 13 are the same size and are both a single, continuous surface, reducing the shadow under the bridging and improving the light transmittance uniformity of the ITO assembly with reduced bridging shadows. Preferably, the carrier sheet 10 is a glass sheet.

[0025] In one embodiment, the first ITO layer 11 has the same size as the second ITO layer 13, and the length of the first separator 12 is greater than the length of the first ITO layer 11. The width of the first separator 12 is greater than the width of the first ITO layer 11, further ensuring that the first ITO layer 11 and the second ITO layer 13 do not experience a short circuit.

[0026] Please see Figure 3 The metal trace layer 14 has several connectors 20 along its edge for easy and quick electrical connection to the FPC on the display screen to transmit electrical signals. The metal trace layer 14 is the internal wiring of the ITO component to reduce the shadow of the bridge point, and is electrically connected to the first ITO layer 11 and the second ITO layer 13 respectively.

[0027] Furthermore, the first ITO layer 11 and the second ITO layer 13 are arranged in parallel to further improve the light transmission uniformity on the ITO component that reduces the shadow of the bridge point.

[0028] Furthermore, the first ITO layer 11 and the second ITO layer 13 are aligned. If the sizes of the first ITO layer 11 and the second ITO layer 13 are inconsistent, the touch function of some ITO layers will fail, and the ITO material will be wasted.

[0029] In one embodiment, the size of the carrier sheet 10 is larger than the size of the first ITO layer 11, the second ITO layer 13 and the metal wiring layer 14, respectively, so that the carrier sheet 10 can fully support the first ITO layer 11, the second ITO layer 13 and the metal wiring layer 14.

[0030] Furthermore, the support plate 10 is a cuboid, cylinder, or cube.

[0031] Preferably, both the first isolation membrane 12 and the second isolation membrane 15 are OC layers.

[0032] A display screen includes the aforementioned ITO component for reducing bridge point shadows, which reduces the shadow under the bridge and improves the light transmission uniformity on the ITO component for reducing bridge point shadows, thereby improving the display effect of the display screen.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
