EN Purpose: The aim of this work is to perform the review of the recent most important results of experimental and theoretical investigations connected with the organic light emitting devices (OLEDs). Design/methodology/approach: The recent achievements in the field of designing, fabricating and clarification of the OLEDs operation have been presented. The possibilities of numerous, present and future applications of these devices have been pointed out. Findings: We show that fundamental differences among organic and inorganic devices result from differences between inorganic and molecular semiconductor materials. No charges are present in OLED devices without charge injection. Emission is due to radiative transitions from the neutral excited states to the ground states. We pointed out the important role that the OLEDs play in display design (even the flexible ones). Research limitations/implications: The main disadvantage of OLEDs is reported to be short their lives (particularly the blue OLED) and weak resistivity to moist but improvements are advancing. Originality/value: Our review concerns the most recent experimental and theoretical publications in the OLED investigation. We also show some recent examples of OLEDs application.
