Test LCD screen

LCD display inspection can detect potential problems and defects early, thereby improving product reliability and user experience.

Our LCD display inspection process usually includes the following aspects:

(1) Bright spot and dark spot inspection:

By displaying white and black patterns on a black background and carefully observing the bright spots and dark spots on the screen surface, we can determine whether there are bright spot and dark spot defects.

(2) Bad spot inspection:

By displaying a series of color grids and patterns, we can detect whether there are bad spots on the screen.

Bad spots mainly include bright spots, black spots and dark spots, which are judged by comparing the consistency between standard colors and the actual colors of the display.

(3) Color shift inspection:

By displaying a series of red, green, blue and other color blocks, we can detect whether the display has color shift problems. Color shift may cause the image to be unrealistic and look uncomfortable.

(4) Grayscale consistency inspection:

By displaying a series of grayscale images, we can detect whether the display screen performs consistently at different grayscale levels. If the grayscale is inconsistent, it will cause loss of image details and inaccurate colors.

(5) Observation angle inspection:

By adjusting the viewing angle, we can observe the display effect of the display screen at different angles. This test can reveal if there is an issue with restricted viewing angle when viewing the display.
