Abstract: A display panel vacuum suction system includes a control device, a robot arm, and a vacuum device. The robot arm includes two or more retractable rods, and each of the retractable rods is connected with a vacuum plate. Each vacuum chamber is disposed in each of the vacuum plates, and each vacuum hole is disposed on a surface of each of the vacuum plates, wherein each vacuum chamber is connected with the vacuum device by a suction pipe. The control device controls expansion and retraction of the retractable rods of the robot arm, so that the vacuum plates connected with the retractable rods can be combined to pick up a single display panel or pick up two display panels respectively. By combining vacuum plates, and controlling the opening or closing of the vacuum holes of each of the vacuum plates, different sizes of display panels can be sucked.

Abstract: The disclosure provides a display module and an assembling method thereof. A blind hole protective film is attached to a blind hole area of an LCD panel before light-shading adhesives are coated on the blind hole area. Therefore, the light-shading adhesives may be predeterminedly coated on a notch, thereby improving coating accuracy and coating appearance of the light-shading adhesives. By cooperation of the first light-shading layer and the second light-shading layer, a problem that display effect and camera function of products are affected because light in backlight module leaks to the blind hole area is prevented, and the blind hole area is effectively prevented from being interfered by foreign matters.

Abstract: The present disclosure provides an under-screen fingerprint identification device, a display panel, and a display device. In the present disclosure, light control films are added to pixel opening areas to distinguish fingerprint identification light from normal display light, and image sensors are set to only identify invisible light, so invisible light can be transmitted to the image sensors only through pinholes in a pinhole layer, thereby improving a signal-to-noise ratio of a fingerprint identification signal.
