Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to backlight module picture detection equipment. Background Art

[0002] The display panel is an important component for displaying images and text in modern electronic devices. It is composed of a series of electronic components and can display corresponding images according to the input electrical signals. Display panel technology is constantly developing, and new display technologies such as MicroLED and QLED are gradually being introduced to the market. They provide higher performance and more application possibilities. With the advancement of technology, display panels are constantly improving in terms of resolution, color performance, energy consumption and response speed. In the production of these display panels, it is necessary to test the normal operation of the backlight module and evaluate the color and brightness performance of the display panel.

[0003] Traditionally, the normal operation of the backlight module of the display panel product and the evaluation of the color and brightness performance are tested by using two methods, BLU lighting and color brightness detection. Two different sets of detection equipment are required, and the detection cost is relatively high. In addition, the BLU lighting detection part is manually inspected. A few of them are composed of lighting AOI plus separate color brightness detection equipment. However, such equipment is inefficient, costly, occupies a large space, and has a low secondary positioning lighting rate, which cannot meet the current production and detection needs of the backlight module of the display panel product.
