Problems solved by technology

However, in the prior art, since the transmission data is converted into a code sequence using a fixed seed value, there is a problem that a certain pattern that is not completely random is continuously generated
In this way, the EMI reduction effect is halved

Embodiment Construction

[0017] Embodiments disclose a display driving device and a display device including the display driving device, which can improve the effect of reducing electromagnetic interference (EMI) by converting transmission data into a completely random code sequence.

[0018] Embodiments disclose a display driving device and a display device including the display driving device that support high-speed data communication by defining a variable data packet length in a packet header, thereby allowing time for a configuration mode to operate at a low frequency to be reduced.

[0019] Embodiments disclose a display driving device and a display device including the display driving device, and when a communication abnormality occurs due to an unexpected variable during communication between a timing controller and a source driver, a communication abnormal state can be restored to a normal state.

[0020] In an embodiment, a recovery protocol or a recovery mode may be defined as a protocol or ...

Abstract

The present disclosure discloses a display driving device and a display device including the same, which allow transmission data to be converted into a completely random code sequence. The display device may scramble transmission data into a pseudo-random binary sequence (PRBS) using a linear feedback shift register (LFSR), and may change a seed value of the LFSR every time the scrambling is performed.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 2019-0174233 filed on December 24, 2019, the entire disclosure of which is hereby incorporated by reference. technical field [0003] The present invention relates to a display device, and more particularly, to a display driving device capable of improving electromagnetic interference (EMI) and a display device including the same. Background technique [0004] Generally, a display device includes a display panel, a source driver, a timing controller, and the like. [0005] The source driver converts digital image data supplied from the timing controller into data voltages and supplies the data voltages to the display panel. The source driver may be integrated into an integrated circuit chip (IC chip), and may be configured as a plurality of IC chips in consideration of the size and resolution of the display panel. [0006] Meanwhile, a sc...
