To achieve an on-vehicle display device which is improved in accuracy of temperature measurement and luminance correction of an OLED panel more than before.SOLUTION: A plurality of external temperature sensors 4 are mounted on the other surface 2b on the side opposite to one surface 2a of an OLED panel 2 on which a video is displayed. The temperature sensor 4 is connected to an on-vehicle control part 5, which is different from a display control part 3 for performing driving control of the OLED panel 2, and outputs a signal to the on-vehicle control part 5. The display control part 3 calculates a deterioration amount of each pixel formed of the OLED based on the temperature information on the OLED panel 2 calculated by the on-vehicle control part 5, and performs the driving control of the OLED panel 2 based on the deterioration amount.SELECTED DRAWING: Figure 1

    【課題】従来よりもOLEDパネルの温度測定および輝度補正の精度が向上した車載用表示装置を実現する。【解決手段】OLEDパネル2のうち映像が表示される一面2aとは反対側の他面2bには、複数の外付けの温度センサ4が取り付けられている。温度センサ4は、OLEDパネル2の駆動制御を行う表示制御部3とは異なる、車載制御部5に接続され、信号を車載制御部5に出力する。表示制御部3は、車載制御部5で算出されたOLEDパネル2の温度情報に基づいてOLEDによりなる各画素の劣化量を算出し、当該劣化量に基づいてOLEDパネル2の駆動制御を実行する。【選択図】図1
