Abstract

The invention discloses a heat dissipation composite layer and a preparation method thereof, and a display panel. The heat dissipation composite layer comprises a support layer; a buffer layer which is arranged on the supporting layer, wherein a groove is formed in the upper surface, away from the supporting layer, of the buffer layer; and a heat conduction layer which is arranged in the groove; compared with the prior art, the heat dissipation composite layer provided by the invention has the advantages that the transverse conductivity of heat can be improved, the temperature and temperatureuniformity of the display panel are improved, the problem of screen afterimage of the display panel is further improved, and the display effect is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a heat dissipation composite layer, a preparation method thereof, and a display panel with the heat dissipation composite layer. Background technique [0002] With the continuous development of OLED technology, the performance requirements of customers for the screen are also constantly improving, and the problem of afterimage on the screen has attracted more and more attention from customers. [0003] Screen afterimage refers to lighting the screen under the black and white picture (checkerboard picture) for a period of time, then switching to the white picture, and observing the time required for the afterimage of the previous picture in the white picture to disappear. The faster the afterimage disappears, the faster the afterimage disappears. The better the display performance of the screen, the experiment found that the time for the afterimage to disappear is mainly related ...
