The present disclosure provides a display panel and a display device. The display panel includes: a base substrate including a display unit and a bendable unit, the bendable unit being connected to the display unit and bendable to a back of the display unit; a multiplexer on the bendable unit; and a metal shielding portion on a side of the multiplexer away from the base substrate, wherein an orthographic projection of the metal shielding portion on the base substrate covers an orthographic projection of the multiplexer on the base substrate, and the metal shielding portion is connected to a fixed voltage signal to shield signal interference caused by the multiplexer.

The present invention provides a display panel and a display device. The first enable sub-signal and the second enable sub-signal output by the timing controller are modulated by the logic controller to generate a plurality of enable signals with sequentially changing phases, which can control data signals in a source driver chip to time-sharingly output by multiple sets. This reduces a load capacity of the source driver chip, which is beneficial to reducing costs of the source driver chip. The time-sharing output of the source driver chip can reduce a peak current of each output channel, thus reducing power consumption and lowering the risk of electromagnetic interference (EMI).

A display panel and a driving method thereof are provided, including a time schedule controller and at least one driver integrated circuit (driver IC). Pulse width modulation (PCM) data between the time schedule controller and the driver IC is transmitted in a decoded manner, and pulse amplitude modulation (PAM) data is transmitted in an undecoded manner, reducing a transmission rate between the time schedule controller and the driver IC, and thereby reducing or eliminating risks of electromagnetic interference (EMI). Furthermore, using this transmission method can reduce the number of latches used in the driver IC.

Common noise generated when display data is supplied to a light-emitting element, for example, may affect a first light-receiving signal output by the first pixel and a second light-receiving signal output by the second pixel. A first current is generated using the first light-receiving signal and a ramp signal, and a second current is generated using the second light-receiving signal and a first potential. The differential input circuit is controlled so that the first current and the second current have the same current value, whereby common noise can be removed from the first light-receiving signal.
