[0029] Example 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 a thermally conductive patch to achieve heat conduction, and is additionally provided on the backplane layer 110 There are a plurality of heat dissipation holes, so as to utilize the temperature difference effect between the inside and the outside of the display panel 10, so that the high temperature gas inside and the low temperature outside gas exchange heat through the heat dissipation holes in a convective manner.
[0032] The heat dissipation layer 120 includes a graphite layer 121, a foam layer 122 and a metal l...
