Problems solved by technology

At present, for the structure of curved surface devices, in order to increase the three-dimensional design aesthetics and consumer demand, the curvature of the cover plate is limited as much as possible to achieve a more three-dimensional appearance, but the visual deformation caused by the limited curvature has certain standards.
However, there is currently no comprehensive evaluation method for evaluating whether the curvature radius of curved surface devices meets the optical distortion standard

Embodiment Construction

[0022] see figure 1 , figure 1 It is a flowchart of a method for evaluating the radius of curvature of a curved surface device provided by an embodiment of the present invention. The evaluation method includes the following steps S1-S4:

[0023] Step S1: Provide a picture with a planar pattern, the picture is in grayscale format, use optical modeling software to process and analyze it, and obtain the optical visual deformation of the pattern under the set brightness, set viewing angle and set curvature radius Image.

[0024] In this embodiment, the optical modeling software used is LightTools. LightTools provides a variety of methods for simulating light sources, including: the simulation of the entire light source model, the construction of apodized light sources and the use of light data files. If you want to use the image as a light source and inject it into the system to observe the changes of the image after passing through the system, you can use the apodized light s...

Abstract

A method for evaluating the radius of curvature of a curved surface device, the evaluation method comprising the following steps: providing a gray-scale format image with a plane pattern, using optical modeling software to process and analyze it, and obtaining a set brightness and a set viewing angle and the image of the optical visual deformation of the pattern under the set radius of curvature; respectively measure the maximum optical deformation in the first direction and the maximum optical deformation in the second direction in the image; change the set radius of curvature to obtain different settings The maximum optical deformation in the first direction and the maximum optical deformation in the second direction under the radius of curvature; respectively establish the regression curve equation of the curvature radius and the maximum optical deformation in the first direction and the second direction, and use the regression curve equation As an equation for evaluating whether the radius of curvature of a curved device meets the optical distortion criteria. This evaluation method can achieve optimal ex-ante evaluation.

Description

technical field [0001] The invention relates to the field of curved surface display, in particular to a method for evaluating the radius of curvature of a curved surface device. Background technique [0002] In response to the design trend of the consumer end of the curved surface device, the curvature design of the curved surface device needs to consider the actual visual effect. At present, for the structure of curved surface devices, in order to increase the three-dimensional design aesthetics and consumer demand, the curvature of the cover plate is limited as much as possible to achieve a more three-dimensional appearance, but the visual deformation caused by the limited curvature has certain standards. However, there is currently no overall evaluation method for evaluating whether the radius of curvature of a curved surface device meets the optical distortion standard. Contents of the invention [0003] A method for evaluating the radius of curvature of a curved surf...
