Abstract: A method for preparing a display panel, a display panel, and an electronic device are provided. In the method for preparing a display panel provided in the embodiments of the present disclosure, a TFT device is prepared on a TFT substrate, the TFT device is then transferred from the TFT substrate to a circuit board in a manner of transfer for twice, and a light-emitting device is transferred on the circuit board, so that a display panel driven by the TFT device is obtained. The production costs are low, and the display panel can achieve better electrical performance.
