AI Technical Summary

Problems solved by technology

High voltage noise may be generated periodically when the source driver drives the display panel at horizontal line intervals
[0007] High-voltage noise may affect low-voltage range circuits to cause abnormal operation, and may affect low-voltage input data input during horizontal blank periods, which may affect display panel driving
[0008] As an example, the problem with existing technology is that when data packets such as scrambled reset signals are affected by high-voltage noise, important control data packets may not be received normally, and thus the display panel may not be driven normally

Embodiment Construction

[0019] Embodiments disclose a display driving device capable of avoiding the influence of high-voltage noise in driving a display panel and a display device including the display driving device.

[0020] 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.

[0021] 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.

[0022] 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...

Abstract

The present disclosure discloses a display driving device and a display device including the same, which enable the influence of high voltage noise to be avoided in display panel driving. The display device includes a timing controller configured to transmit a communication signal, which includes a blank pattern and line data, at a horizontal line interval, and a source driver configured to restore the blank pattern and the line data in the communication signal and drive a display panel using the blank pattern and the line data. The timing controller may include a configuration packet in the blank pattern and position the configuration packet in an end period of the blank pattern.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 2019-0174234 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 avoiding the influence of high-voltage noise in driving a display panel 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...
