[0019] Please refer to Figure 1 and Figure 2 , the utility model provides a structure for reducing visible foreign matter in transparent products, including a touch panel 1 and a liquid crystal display panel 3;

[0020] The touch panel 1 includes a glass cover plate 11, an upper optical adhesive layer 12, an upper electrode layer 13, a lower optical adhesive layer 14 and a lower electrode layer 15 arranged in sequence from top to bottom;

[0022] In order to solve the problem of low yield of touch LCD screen due to dust particles mentioned in the background technology, one traditional method is to improve the cleanliness of the bonding room. Another solution is to appropriately increase the haze value of the touch panel 1 to reduce the visibility of dust particles through a certain degree of atomization.

[0023] In the embodiment of the utility model, by adding a layer of atomized film 2 to the bonding surface of the touch panel 1 and the liquid crystal display panel 3, this is an economical solution without changing the process. Properly increasing the haze does not affect the transmittance of the product and improves the overall haze of the product. The high haze touch panel 1 can cover some micron-level (<80μm) dust particles in terms of vision and reduce their visibility. In this way, the bonding yield can be greatly improved.

[0024] Preferably, the haze value of the atomized film 2 is greater than or equal to 10% and less than or equal to 30%. In this embodiment, after measurement, the haze value is between 10-30%, which can achieve a balance between display performance and invisibility of dust particles.

[0025] Preferably, the thickness of the atomizing film 2 is greater than or equal to 100 μm and less than or equal to 150 μm.

[0026] Preferably, the atomizing film 2 comprises a transparent substrate layer, and an atomizing layer is disposed on the transparent substrate layer.

[0027] Preferably, diffusion particles are distributed on the atomization layer, and the diffusion particles are organic particles or inorganic particles.

[0028] Preferably, the atomization layer comprises a plurality of convex structures of different sizes, and the convex structures may be hemispherical or conical. In this embodiment, the atomization layer is composed of convex structures of different sizes, and the specific shape may be hemispherical or conical, so as to achieve the atomization effect of light refraction.

[0029] Compared with the prior art, the beneficial effect of the utility model is as follows: the utility model adds a layer of atomizing film on the bonding surface of the touch panel and the liquid crystal display panel to increase the haze, thereby improving the overall haze of the product without affecting the transmittance of the product. The high haze touch panel can visually cover some micron-sized dust particles, reduce the visibility of the dust particles, and can effectively improve the bonding yield.
