Abstract

The invention provides a folding display backboard and a display terminal. The folding display backboard comprises a rigid supporting layer and a heat dissipation layer, the rigid supporting layer comprises a first plane part, a second plane part and a bent part located between the first plane part and the second plane part, and the heat dissipation layer is arranged on the rigid supporting layer. The heat dissipation layer comprises a first heat dissipation part located on the first plane part, a second heat dissipation part located on the second plane part and a bridging part located on the bent part, the bridging part comprises a plurality of first heat conduction pieces arranged at intervals, and the first heat conduction pieces are connected with the first heat dissipation part and the second heat dissipation part. By arranging first heat conduction pieces, which are arranged at intervals, of the bridging part in the heat dissipation layer, the first heat dissipation part and the second heat dissipation part are integrated into a whole, thus, the heat dissipation performance is improved, wrinkles are not easy to generate when the first heat conduction pieces are arranged at intervals, the possibility of abnormal display is reduce, and the high heat dissipation performance and the high display quality are both achieved.

Description

technical field [0001] The present application relates to the display field, in particular to a foldable display backplane and a display terminal. Background technique [0002] At this stage, folding screens are limited by heat dissipation requirements, and graphite materials usually need to be attached behind the rigid support layer as a heat dissipation layer. However, if the graphite heat dissipation layer participates in the folding in the bending area, since the graphite has a multi-layer flake structure, the graphite is easy to delaminate, and the delamination and fracture of the graphite will cause surface wrinkles, and there may be poor display phenomena such as imprints when viewed from the front of the screen. And if the graphite heat dissipation layer is disconnected at the bending area so that it does not participate in the folding, the graphite on both sides of the bending area will not be able to communicate, resulting in a problem of reduced thermal conductivi...
