Temperature sensor, method for manufacturing temperature sensor, and display device to which temperature sensor is applied
There are disclosed a temperature sensor and a method for manufacturing the same. The temperature sensor comprises; a sensor unit including an organic light emitting layer including a delayed fluorescent material; a temperature transfer unit located below the sensor unit to transfer an external temperature to the sensor unit; a first electrode located on the sensor unit; a second electrode located below the sensor unit to be spaced apart from the temperature transfer unit; and a light intensity measuring unit located below the second electrode and measuring the intensity of light emitted from the organic light emitting layer. The temperature sensor can measure a temperature by using a change in the intensity of light using delayed fluorescence, thereby providing improved sensitivity.
