The invention provides a double-sided white-light organic light-emitting diode display device and a manufacturing method thereof. A quantum dot photoluminescence film is arranged between the white-light organic light-emitting diode light-emitting layer and a color film layer, and the quantum dot photoluminescence film is provided with a conversion part which is corresponding to the red color resistance of the color film layer and used for converting blue light into red light and a conversion part which is corresponding to the green color resistance of the color film layer and used for converting blue light into green light. The device can solve the technical problems that in the prior art, the color gamut is low, the energy utilization rate is low, and power consumption is high.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a double-sided white light organic light emitting diode display device and a manufacturing method thereof. Background technique [0002] Organic light emitting diode (OLED) display devices have the advantages of self-illumination, simple structure, light and thin, fast response speed, wide viewing angle, low power consumption, and flexible display. Therefore, OLED display devices have been favored by people in recent years. focus on. [0003] The OLED device used for display is one of the important elements in the OLED display device. In the prior art, the color display of OLED devices is mainly realized through the following two methods. One method is to prepare an OLED device with three sub-pixels of red, green and blue by using a fine metal mask (FineMetal Mask, FMM), but this method is limited by the FMM, resulting in low resolution. Another method is to achieve color dis...
