Samsung patents display driver that checks signal quality in real time
Samsung has filed a patent for a display device that uses its source driver to run an "eye margin test" on the data signals sent to the screen. This process checks how clean and reliable the data is as it travels to the pixels, allowing the system to verify signal quality and adjust display settings on the fly.
In the filing’s own words
An example display device includes a display panel having a plurality of pixels and data lines, a timing controller for providing image data and an eye margin test signal, and a source driver for performing an eye margin test on the received data to generate and output data signals. The source driver generates eye margin test result data and corresponding data signals based on the test. Accordingly, the display device can visually verify interface signal integrity and optimize display driving characteristics in real time.
What exactly they claim (claim 1)
1. A display device comprising: a display panel including a plurality of pixels and a plurality of data lines connected to the plurality of pixels; a timing controller configured to receive image data, and output data generated based on the image data and an eye margin test signal, wherein the eye margin test signal is configured to instruct testing of an eye margin; and a source driver connected to corresponding data lines among the plurality of data lines, wherein the source driver is configured to receive first data among the data output from the timing controller and the eye margin test signal, wherein the first data corresponds to pixels connected to the data lines, perform the eye margin test on the first data to generate an eye margin test result data, generate a plurality of data signals corresponding to the eye margin test result data, and output the plurality of data signals to the data lines.
