Display device
By incorporating a heat path alteration section within the organic light-emitting display device, the heat from the connecting wires is dissipated to the cathode electrode, thus resolving the issues of polarizer melting and vertical line contamination caused by overheating of the connecting wires, thereby achieving reduced power consumption and temperature.

AI Technical Summary
Technical Problem
In organic light-emitting display devices, electrical or signal deviations between connecting lines can cause the connecting lines to overheat, potentially leading to polarizer melting and vertical line contamination, while also increasing power consumption.
Method used
By setting a heat path alteration section between the connecting line and the polarizer, and connecting it to the cathode electrode, the heat propagation path is changed and the heat is dissipated to the cathode electrode, preventing the polarizer from melting and dispersing heat through the cathode electrode.
Benefits of technology
It effectively prevents the polarizer from melting, reduces the peak temperature of the display panel, reduces vertical line contamination, and lowers power consumption.
