The roller body includes a plurality of chambers therein, and the chambers are separated from each other. The die-suction portions are located on the surface of the roller body in columns. The die-suction portions for each column correspond to one of the chambers, and each of the die-suction portions has a die suction region and a gas channel that passes through the die suction region. The gas control device is connected to the chambers and disposed on the roller body. The gas control device selectively sucks the air from a specific chamber, such that each of the die-suction portions on the specific chamber sucks an LED die by the corresponding gas channel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Die-positioning device, die-positioning system having the same, and die-positioning method of LED display board","description":"A die-positioning device includes a roller body, a plurality of die-suction portions, and at least one gas control device.
