Color change response time detection method and device of color change device and computer readable storage medium

Abstract

The invention provides a color change response time detection method and device of a color change device and a computer readable storage medium. The detection method comprises the following steps: performing video shooting on a color changing process of a color changing device; comparing the color in the color changing process of the color changing device in the video with a standard color; and obtaining the time interval of the color corresponding to the first standard color and the second standard color in the color changing process of the color changing device as the color changing response time of the color changing device. According to the detection method, on one hand, the test difficulty of light-proof and non-uniform light-transmitting color-changing devices is solved, and no test is needed in a semi-finished product stage, so that the production efficiency and the product quality are improved; on the other hand, the situation that large deviation exists between a measured value and an actual value due to the problem of color change response time standard definition can be avoided. The detection method provided by the invention has the characteristics of simple process and high detection accuracy and reliability.

Description

technical field [0001] The invention relates to the technical field of detecting the color change response time of a color changing device, in particular to a detection method, a detection device and a computer-readable storage medium for the color change response time of a color changing device. Background technique [0002] Color-changing devices (such as devices based on electrochromic principles, photochromic principles, etc.) have begun to be used more and more, such as exterior glass of buildings, color-changing housings of electronic equipment, and color-changing clothing. Among them, several most important index tests of color-changing devices, such as color-changing response time and color-changing efficiency, are mainly tested and analyzed by the change of transmittance of the device in academia and industry. Taking the color change response time as an example, the color change response time of the color change device is roughly defined by the difference between th...

Problems solved by technology

[0003] The test scheme based on the change of transmittance can only be used for transparent devices, and it is not applicable if there are other opaque films or light passes through inhomogeneous media, such as color-changing devices with textured films as substrates, frosted glass, etc. Composite structure

In this case, the performance of the product can only be monitored in the middle of the process. The performance test of the semi-finished product is done before the color-changing device is attached to other film layers, and there is nothing to be done for the test of the finished product.

[0004] In addition, due to the fixed and single definition standard in conventional technology, the test results cannot reflect the actual situation of the sample.

Generally, 90% of the time ΔT for a color-changing device to change color from one color state (such as a transparent state) to another color state (such as a red colored state) is used as the color-changing response time, but this test method does not accurately reflect human the actual senses of the eye
