The input device includes a light source, a force sensor, and a controller. The force sensor is configured to sense a force applied to a tip of the input device and generate a first sensing signal corresponding to the sensed force. The controller is electrically connected to the light source and the force sensor, and configured to receive the first sensing signal and control the light source to generate light pulses in response to the first sensing signal according to a predefined protocol."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Input device and display system having the same","description":"An input device capable of optically communicating with an electronic apparatus is provided.
