Abstract

The application discloses a display panel and a driving method, which includes a timing controller and at least one driver IC; the PWM data between the timing controller and the driver IC is transmitted in a decoded form, and the PAM data is transmitted in an undecoded form. The transmission reduces the transmission rate between the timing controller and the driver IC, thereby reducing or eliminating the risk of EMI; and the transmission in this way can reduce the number of latches used in the driver IC.

Description

technical field [0001] The present application relates to the field of display technology, in particular to the field of active matrix Mini-LED technology, and in particular to a display panel and a driving method. Background technique [0002] In AM (Active Matrix, Active Matrix / Active Matrix) Mini-LED PWM+PAM driving mode, the timing controller (Tcon) transmits corresponding data to Driver IC (driver IC) through the Mini-LVDS protocol. If Tcon If the corresponding data is decoded and then transmitted, the transmission line based on the Mini-LVDS protocol will bear a higher transmission rate, which leads to a serious EMI (Electromagnetic Interference, electromagnetic interference) risk. [0003] Moreover, to transmit the corresponding data through the above situation, the Driver IC needs to decode more data and configure more storage devices to buffer the decoded data. Contents of the invention [0004] The present application provides a display panel and a driving metho...
