Electroluminescent display panel, driving method thereof, driving device and display device

A driving device for an electroluminescent display panel, comprising:

• a temperature sensor, a temperature detecting circuit, a controller, and a driving voltage generator;
• wherein the temperature sensor is configured to detect a temperature of the electroluminescent display panel;
• the temperature detecting circuit is configured to determine whether a detected temperature of the electroluminescent display panel is within an operating temperature range, whether the detected temperature of the electroluminescent display panel is higher than a first standard temperature or lower than a second standard temperature;
• the first standard temperature is higher than or equal to the second standard temperature;
• the controller is configured to:
• in response to a detected temperature of the electroluminescent display panel being within the operating temperature range and being higher than the first standard temperature, causing the driving voltage generator to adjust a driving voltage of the electroluminescent display panel to a first driving voltage lower than a standard driving voltage;
• and in response to the detected temperature of the electroluminescent display panel being within the operating temperature range and being lower than the second standard temperature, causing the driving voltage generator to adjust the driving voltage of the electroluminescent display panel to a second driving voltage higher than the standard driving voltage.
