Display device and driving method applicable thereto

摘要

A driving method applicable to a display device including multiple display driving circuits, includes: the display driving circuits synchronously receiving a start pulse and generating a synchronous timing signal; a previous display driving circuit sending out a first signal to a rear display driving circuit, so that the rear display driving circuit detects and stores a signal reception delay, the display reception delay denoting a delay between the synchronous timing signal and the first signal received by the rear display driving circuit; after storing the display reception delay, the rear display driving circuit temporarily stopping receiving a system clock signal and temporarily stopping generating the synchronous timing signal; and the previous display driving circuit sending a second X signal to the rear display driving circuit to wake up the rear display driving circuit for preparing to receive a display data.

1. A driving method applicable to a display device including a plurality of display driving circuits, including:
synchronously receiving a start pulse and generating a synchronous timing signal by the display driving circuits; delivering a first signal from a previous display driving circuit to a rear display driving circuit, so that the rear display driving circuit accordingly detects and stores a signal reception delay denoting a delay between the synchronous timing signal and the first signal received by the rear display driving circuit; temporarily stopping receiving a system clock signal and temporarily stopping generating the synchronous timing signal by the rear display driving circuit after storing the signal reception delay in the rear display driving circuit; and delivering a second signal from the previous display driving circuit to the rear display driving circuit to wake up the rear display driving circuit for preparing to receive a display data; wherein, the rear display driving circuit receives the first signal from the previous display driving circuit; the rear display driving circuit accordingly detects and stores the signal reception delay according to the received first signal and the synchronous timing signal; after the rear display driving circuit temporarily stops receiving the system clock signal and temporarily stops generating the synchronous timing signal, the rear display driving circuit resumes receiving the system clock signal if the rear display driving circuit receives the second signal; the rear display driving circuit re-generates the synchronous timing signal according to the signal reception delay if the rear display driving circuit receives a third signal from the previous display driving circuit; and the rear display driving circuit receives a fourth signal from the previous display driving circuit for preparing to receive the display data.
