BRIGHTNESS CONTROLLABLE ELECTRO LUMINESCENCE DEVICE WITH TACTILE SENSOR SENSING INTENSITY OF FORCE OR INTENSITY OF PRESSURE, FLAT PANEL DISPLAY HAVING THE SAME, MOBILE TERMINAL KEYPAD HAVING THE SAME

摘要

The present invention relates to an electroluminescent device which is adjustable in illumination through contact force strength or pressure strength. To this end, in particular, the substrate; A first electrode provided on the bottom surface of the substrate; A light emitting layer provided on the lower surface of the first electrode; A second electrode provided on the bottom surface of the light emitting layer; A tactile sensor capable of sensing force strength or pressure strength on a lower surface of the second electrode; And a control unit connected to the tactile sensor and controlling an electric field change between the first electrode and the second electrode based on the output of the tactile sensor. An electroluminescent device capable of adjusting illuminance is disclosed.;Organic electroluminescent device, inorganic electroluminescent device, tactile sensor
