Description

a color analyzer

Technical field

The utility model relates to the technical field of color analysis, in particular to a color analyzer.

Background technique

A color analyzer is an industrial machine that can measure the brightness and chromaticity of LCD monitors and various other display devices at a speed of up to 20 times/second. Color accuracy, also known as color reproduction accuracy, is a measure of display performance. One of the important parameters is used to characterize the color reproduction capability of the screen, which also means the degree to which the display screen can truly display each color on the screen. Moreover, due to the limitations of the screen's voltage drop and manufacturing process, the color of the screen is usually uneven. Therefore, when an electronic device equipped with a screen leaves the factory (or the screen is repaired), the color of the screen needs to be detected. However, With existing color analyzers, the operator can only pick up the probe and point it at the device display that needs to be measured to test the brightness and chromaticity of the device. However, when performing color testing on the device display, it is usually necessary to adjust the probe and The distance between device monitors can more accurately analyze the brightness and chromaticity of device monitors based on different distances. Existing color analyzers cannot accurately adjust the distance between the probe and device monitors, resulting in inaccurate color analysis results. At the same time, , in order to improve the accuracy, it is necessary to detect different areas of the display screen to improve the color fidelity of the display screen. When the existing color analyzer detects different areas of the display screen, it requires a hand-held probe to detect different areas of the display screen. If detected, the position of the display screen will be inaccurate, which will affect the accuracy of the color analysis results.

Therefore, providing a color analyzer that moves the display under test in the horizontal plane and moves the probe in the vertical direction and can perform color analysis on different areas of the display is a problem worthy of study.
