Problems solved by technology

[0003] In order to meet the requirements of the wide color gamut mode, technicians have been developing materials that can emit red light with a wavelength of 610 nanometers (Nanometer, nm) to 650nm. In the prior art, materials that can emit red light with a wavelength of 610nm to 650nm They are all organic synthetic materials. The energy conversion rate of this organic synthetic material is relatively low. When the equipment uses this material, there will be color distortion and other phenomena.

Abstract

The invention relates to the technical field of the OLED display and particularly relates to an OLED display module and a display for improving the energy conversion rate while satisfying red light with the wavelength of 610nm to 650nm. In an embodiment of the invention, the OLED display module includes a sub-pixel unit which includes a cathode, an anode and a light emitting layer, wherein the cathode is located on the anode, the light emitting layer is located on the anode, the and the light emitting layer comprises a quantum light emitting material layer when the sub-pixel unit is used for emitting red light. According to the display module, a color distortion phenomenon can be improved while the emission of red light with the wavelength of 610nm to 650nm is satisfied, and the image quality of the display module is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of OLED displays, and in particular, to an OLED display module and a display. Background technique [0002] With the continuous development of organic light-emitting diode (Organic Light-Emitting Diode, OLED) display technology, the DCI-P3 wide color gamut mode has gradually been favored by users. [0003] In order to meet the requirements of the wide color gamut mode, technicians have been developing materials that can emit red light with a wavelength of 610 nm (Nanometer, nm) to 650 nm. In the prior art, materials that can emit red light with a wavelength of 610 nm to 650 nm They are all organic synthetic materials. The energy conversion rate of this organic synthetic material is relatively low. When the equipment uses this material, there will be color distortion and other phenomena. [0004] To sum up, there is an urgent need for an OLED display module that can improve the co...
