Description

Technical Field

[0001] The present invention relates to the technical field of organic electroluminescent elements, and in particular to an intelligent driving system and method for organic electroluminescent elements. Background Art

[0002] With the rapid development of optoelectronic technology, organic electroluminescent elements have achieved remarkable application results in the display field due to their advantages such as self-luminescence, no viewing angle limitation, fast response, power saving, simple process and full color. However, in practical applications, the voltage driving value of organic electroluminescent elements has a crucial influence on their luminous performance. When the voltage driving value is too low, it cannot provide enough energy, resulting in low brightness of the element. When the voltage driving value is too high, it accelerates the aging and degradation of organic materials, affecting the stability and life of the element.

[0003] Traditionally, voltage driving values ​​are set by experienced staff. When a light-emitting instruction is received at a certain moment, the relevant staff sets the voltage driving value to drive and control the organic electroluminescent element. After the control is completed, if it is detected that the brightness of the organic electroluminescent element is lower than the light-emitting instruction, the driving voltage value is increased. If it is detected that the brightness of the organic electroluminescent element is higher than the light-emitting instruction, the driving voltage value is reduced. This driving method requires repeated adjustment of the voltage driving value, and it is often difficult to achieve precise control, resulting in large fluctuations in the light-emitting performance of the organic electroluminescent element, reducing the light-emitting efficiency of the organic electroluminescent element, and affecting its display effect and application life.
