Problems solved by technology

[0002] The signal transmission of the current light-emitting diode driver integrated circuit (LED driver IC) mostly uses single-ended signal or differential signal transmission, but the transmission speed of single-ended signal is limited. However, if you want to use differential signal transmission, you need to connect the signal line double the number

Abstract

The invention discloses a driving device. The driving device comprises a first complementary metal-oxide-semiconductor circuit and a first comparator, the first complementary metal-oxide-semiconductor circuit is used for outputting a power signal or a pull-down signal according to a first input signal. The first comparator comprises a first non-inverting input end and a first inverting input end. The first non-inverted input end is coupled to the first complementary metal-oxide-semiconductor circuit and is used for receiving a power supply signal or a pull-down signal. The first reverse input end is used for receiving a first reference signal. The first comparator is used for comparing one of the power supply signal and the pull-down signal with the first reference signal to provide a first driving signal.

Description

Technical field [0001] This case relates to display devices and, in particular, to a drive device applied to light-emitting diode displays. Background [0002] The signal transmission of the current light-emitting diode drive integrated circuit (LED driver IC) mostly uses single-ended signals or differential signal transmission, but the transmission speed of single-ended signals is limited, however, if you want to use differential signal transmission, you need to double the number of signal lines. Contents of the Invention [0003] The content of the Invention is intended to provide a simplified summary of the contents of this disclosure so that the reader has a basic understanding of the contents of this disclosure. The contents of this invention are not a complete overview of the contents of this disclosure, and they are not intended to identify important / key elements of the embodiments of this case or to define the scope of this case. [0004] A technical sample of the con...
