Abstract

The present invention provides a display device, a display panel and a display device, wherein the display device comprises: a stacked anode layer, a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer and a cathode layer, The cathode layer is provided with a groove structure, and the inside of the groove structure is filled with a conductive material with a specific heat capacity higher than that of the cathode layer material. Due to the high specific heat capacity of the conductive material filled in the groove structure, the rising temperature of itself is lower after the same amount of heat is absorbed, and the present invention solves the problem that the heat generated by the OLED device in the prior art accumulates around the OLED device and causes the material Degradation leads to the problem of attenuation of OLED device efficiency. Conductive materials with higher specific heat capacity can absorb the heat generated when OLED devices work, reduce the operating temperature of OLED devices, thereby reducing device temperature, reducing thermal decomposition of device materials, and improving OLED devices. service life.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device, a display panel and a display device. Background technique [0002] The application prospects of organic light-emitting diodes (Organic Light-Emitting Diode, referred to as OLED) in flat panel display, lighting and backlight gradually arouse people's widespread attention. [0003] The attenuation of OLED efficiency is inseparable from the material degradation caused by self-luminescence and heat generation. Joule heat during OLED device operation separates the interface, resulting in device failure. Therefore, how to effectively reduce the thermal decomposition caused by the heating of the OLED device is very important to improve the life of the device. Contents of the invention [0004] In view of this, an embodiment of the present invention provides a display device, a display panel, and a display device to solve the problem in the prior art that t...
