Title:
LIGHT SENSITIVE SCREEN
Document Type and Number:
Japanese Patent JP2010152869
Kind Code:
A
Abstract:

To provide a light sensitive screen for detecting a force applied to the light sensitive screen.

The light sensitive screen includes at least one sensing element (12) each being configured to detect a force applied to a position of the light sensitive screen and generate an electrical signal when the force is detected, and a sensor module (81) 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 sensing element of the at least one sensing element and generate an amplified signal (22), compare the amplified signal with a threshold and generate a comparing result (84), and generate a digital signal based on the comparing result (86). The digital signal includes information as to whether the position of the light sensitive screen is touched.
