Abstract
A display panel includes: a glass substrate, a plurality of light emitting units, a plurality of first bonding portions, a silicon-based driver substrate, a plurality of deformation layers. Each deformation layer is at least partially disposed between a respective one first bonding electrode and a hole sidewall of a respective one first conductive through hole. In response to a temperature of the deformation layer being lower than a predetermined temperature, the deformation layer is deformed, and a thickness of the deformation layer is less than a spacing between the first bonding electrode and the hole sidewall of the first conductive through hole.
