摘要： A light sensitive screen includes at least one sensing element each being configured to detect a force applied to a position of the light sensitive screen and generate an electrical signal when a force is detected, and a sensor module configured to receive and process the electrical signal from the at least one sensing element. The sensor module may amplify the electrical signal from one of the at least one sensing element and generate an amplified signal, compare the amplified signal with a threshold and generate a comparing result, and generate a digital signal based on the comparing result, the digital signal including information as to whether the position of the light sensitive screen is touched.

摘要： A touch input system including a stylus and a display device is provided. The stylus includes a battery module, a touch portion, a transducer module and a RF transmitting module. When a contact pressure is acted on the touch portion, the touch portion is electrically connected to the battery module by the contact pressure and emits a light signal. The display region receives and reacts to the light signal, and the contact pressure is transformed into an electrical signal by the transducer module. The RF transmitting module is electrically connected to the transducer module and transmitting the electrical signal. The display device includes a display region and a RF receiving module.
