As the core component of a smartphone, the RGB (red, green and blue) display performance of a cell phone screen directly affects the user's visual experience. In order to ensure the high quality display of cell phone screen, refined inspection technology is crucial. As a high-precision inspection technology, the application of laser autofocus microscope system in the RGB inspection of cell phone screen is getting more and more attention.

Cell Phone Screen RGB Detection

Microscope system to detect cell phone screen RGB principle
 

The laser autofocus microscope system utilizes the self-focusing property of the laser beam, combined with a precision optical system and image processing technology, to achieve accurate detection of RGB pixel points on the cell phone screen. The laser beam passes through a specially designed illumination system to form a high-resolution point light source that scans the surface of the cell phone screen. The system automatically adjusts the focus by monitoring the intensity and phase changes of the reflected light in real time to ensure that a clear and accurate image of the RGB pixels is acquired.
 

Application of laser autofocus microscope system in RGB inspection of cell phone screen

 

1, RGB pixel point analysis: The laser autofocus microscope system is able to observe the RGB pixel points on the cell phone screen in high resolution and analyze their distribution, arrangement and color performance. This helps to assess the display effect and color reproduction ability of the screen, and provides a basis for optimizing the screen manufacturing process.

2, defect detection: using laser autofocus microscopy system, it can accurately detect defects in the RGB pixel points of cell phone screens, such as bad dots, bright dots, dark dots and so on. These defects may lead to a decrease in the screen display effect and affect the user experience. By finding and dealing with these defects in time, it helps to improve the quality of the cell phone screen.

3. Uniformity assessment: The brightness and chromaticity uniformity of the RGB pixel points of the cell phone screen is crucial to the overall display effect. The laser autofocus microscope system can comprehensively detect the uniformity of the screen and provide data support for improving screen performance.
