==Watch Component, Watch, And Method For Manufacturing Watch Component - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18475287 titled 'Watch Component, Watch, And Method For Manufacturing Watch Component

==Simplified Explanation==

The watch component described in the patent application includes a substrate with a multilayer film covering part of it, along with recesses formed in the substrate. The multilayer film consists of three or more layers of a color absorption film containing Cr, with a brightness value of L* equal to or less than 10 in plan view. 

* Substrate with multilayer film and recesses:
  - Substrate has recesses facing the multilayer film
  - Recesses defined by a first side and a second side tilted with respect to the first side
  - Ratio of length of second side along thickness direction to length along orthogonal direction is greater than ½

* Multilayer film composition:
  - Three or more layers of color absorption film containing Cr
  - Brightness value of L* equal to or less than 10 in plan view

== Potential Applications ==
The technology described in the patent application could be used in the manufacturing of high-quality watch components, electronic displays, or other devices requiring color absorption films with specific brightness values.

== Problems Solved ==
This technology solves the problem of achieving precise color absorption and brightness values in watch components or electronic displays, enhancing the visual quality and performance of the devices.

== Benefits ==
The benefits of this technology include improved color accuracy, brightness control, and overall visual appeal in watch components or electronic displays. It also offers a more efficient and reliable manufacturing process for such devices.

== Potential Commercial Applications ==
The potential commercial applications of this technology could include the production of high-end watches, smartwatches, electronic displays for smartphones or tablets, and other consumer electronic devices requiring color absorption films with specific brightness values.

== Possible Prior Art ==
One possible prior art could be the use of multilayer films in electronic displays or optical devices, but the specific combination of substrate with recesses and color absorption film composition as described in the patent application may be novel.

==Original Abstract Submitted==

A watch component of the present disclosure includes a substrate, and a multilayer film covering at least a part of the substrate. A plurality of recesses is formed in a surface, of the substrate, facing the multilayer film. In a cross-sectional view obtained by cutting the substrate in a thickness direction, the plurality of recesses is defined by a first side, and a second side tilted with respect to the first side and being in contact with the first side at an end portion. In the cross-sectional view, a ratio of a length of the second side along the thickness direction of the substrate with respect to a length of the second side along a direction orthogonal to the thickness direction of the substrate is greater than ½. The multilayer film includes three or more layers of a color absorption film composed of a material including Cr. A value of a brightness L* in a L*a*b* color space is equal to or less than 10 in plan view as viewed from the thickness direction of the substrate.
