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

PURPOSE: An illumination controllable LED device including a tactile sensor, a flat display device including the same, a portable key pad device, a robot eye including the same, a robot nose, and an operating method thereof are provided to supply an analog feeing and convenience by applying a tactile sensor to sense the contact intensity or pressure intensity. CONSTITUTION: At lest one light emitting diode(100) emits light based on an electric field formed between a first electrode and a second electrode. A tactile sensor(200) generates an output signal by sensing the contact intensity and pressure intensity. A controller(300) is connected to the tactile sensor and controls the illumination of light by controlling the variation of the electric field based on the generated output signal.
