Embodiment 1

[0030] Such as figure 1 As shown, in this embodiment, the display panel 10 of the present invention includes a backplane layer 110 , a heat dissipation layer 120 , an OLED layer 130 , an optical glue 140 , a touch layer 150 and a polarizer layer 160 .

[0031] The backplane layer 110 is made of metal or other materials with good thermal conductivity and heat dissipation, and is attached and contacted with the heating components of the display panel through the heat conduction patch to achieve heat conduction. There are a plurality of radiating holes, so as to make use of the temperature difference effect between the inside and outside of the display panel 10 , so that the internal high-temperature gas and the external low-temperature gas can exchange heat in the form of heat convection through these radiating holes.

[0032] The heat dissipation layer 120 includes a graphite layer 121 , a foam layer 122 and a metal layer 123 .

[0033] Such as figure 2 As shown, the graphit...

Abstract

The invention discloses a display panel and a preparation method thereof, and a display device. The display panel comprises: a back plate layer; and a heat dissipation layer arranged on the back platelayer, wherein a scattering layer comprises a graphite layer, and the graphite layer is attached to the back plate layer. The display panel and the preparation method thereof and the display device have the beneficial effects that the graphite layer is sputtered onto the back plate layer, so that the thickness of the display panel is reduced, the problem that the graphite layer is easy to fall off is solved, and the life of the display panel is improved; and moreover, the graphite layer, a foam layer and a metal layer in the heat dissipation layer are directly attached, the heat dissipation efficiency is greatly improved, the accuracy of fingerprint unlocking under the screen is improved through the groove formed in the heat dissipation layer, and the heat dissipation effect of the heat dissipation layer is not affected.

Description

technical field [0001] The invention relates to the display field, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] The organic light emitting diode display (Organic Light Emitting Diode, OLED) has gradually begun to replace the traditional liquid crystal display (Liquid Crystal Display, LCD) due to its advantages of low energy consumption, low cost, wide viewing angle, and high response speed. The main structure of the OLED display device includes: a TFT (Thin-film transistor, TFT) substrate, a cathode and an anode, and an organic light-emitting layer sandwiched between the cathode and the anode. Among them, the material of the organic light-emitting layer is very expensive, and its service life is directly related to the production cost and application range of the entire OLED device. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a dis...
