BRIGHTNESS CONTROLLABLE LED ILLUMINATION DEVICE WITH TACTILE SENSOR SENSING INTENSITY OF FORCE OR INTENSITY OF PRESSURE, FLAT PANEL DISPLAY HAVING THE SAME, MOBILE TERMINAL KEYPAD HAVING THE SAME, ROBOT EYE, ROBOT NOSE HAVING THE SAME AND METHOD OF OPERATING THE SAME

摘要

The present invention provides a lighting device that can adjust the illuminance using a tactile sensor that detects contact force strength or pressure strength. To this end, in particular, at least one light emitting diode for emitting light based on the electric field formed between the first electrode and the second electrode; A tactile sensor configured to generate a corresponding output signal by sensing a contact force intensity or a pressure intensity received from a predetermined contact; And a control unit connected to the tactile sensor and controlling the illuminance of the light by adjusting an electric field change of the electric field based on the generated output signal. An adjustable light emitting diode illumination device is disclosed.;Light Emitting Diode, Lighting Device, Tactile Sensor, Fluorescent Layer, Display Panel, Keypad
