Abstract

The invention provides a display device, a display panel and a display device, the display device comprises an anode layer, a hole injection layer, a hole transmission layer, a light-emitting layer, an electron transmission layer, an electron injection layer and a cathode layer which are stacked, a groove structure is arranged on the cathode layer, and the groove structure is filled with a conductive material with higher specific heat capacity than that of a cathode layer material. The specific heat capacity of the conductive material filled in the groove structure is relatively high; under post-absorption of equivalent heat, the self rising temperature is lower. According to the invention, the problem of material degradation caused by heat accumulation at the periphery of an OLED device during working of the OLED device in the prior art is solved. According to the OLED device, the problem that the efficiency of the OLED device is reduced due to the fact that a conductive material withhigh specific heat capacity can absorb heat generated when the OLED device works, and the working temperature of the OLED device is reduced, so that the temperature of the device is reduced, thermaldecomposition of device materials is reduced, and the service life of the OLED device is prolonged.

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...
