Abstract

The invention provides an organic light emitting diode display panel, a display module and an electronic device. The display panel comprises a substrate base plate; an organic light emitting display layer arranged on the substrate base plate; a first inorganic layer arranged on the organic light-emitting display layer; a first organic layer disposed on the first inorganic layer, wherein the material of the first organic layer is doped with a heat conduction material, and the heat conduction material comprises hexagonal boron nitride nanosheets; and a second inorganic layer arranged on the first organic layer. The organic light emitting diode display panel, the display module and the electronic device can improve the heat dissipation effect of the display panel, so that the service life ofthe display panel is prolonged.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of display technology, in particular to an organic light emitting diode display panel, a display module and an electronic device. [0003] 【Background technique】 [0004] Compared with traditional LCDs, Organic Light-Emitting Diode (OLED) devices have the advantages of light weight, wide viewing angle, fast response time, low temperature resistance, and high luminous efficiency, so they are regarded as the next generation of new display technology . [0005] In order to realize the encapsulation of OLED devices, thin-film encapsulation (TFE) has gradually become the mainstream encapsulation technology of OLEDs. TFE often adopts an inorganic / organic / inorganic overlapping film structure. This airtight encapsulation method greatly protects the OLED panel and effectively prevents The damage of external water and oxygen to OLED devices is prevented. However, the highly airtight packaging structure will make it di...
