Publication number: 20190027088Abstract: A display is provided. The display includes a display panel and a timing controller. The timing controller controls the images displayed on the display panel according to a display driving signal from a host and the display driving configuration of the display panel. The timing controller determines whether there is an error in the display driving signal, and calculates an error count. The timing controller determines whether the error count is lower than a predetermined threshold. If so, the timing controller controls the display panel to display the display images normally according to the display driving signal. If not, the timing controller reports a display error signal to the host, so that the host dynamically updates the display driving configuration.Type: ApplicationFiled: June 13, 2018Publication date: January 24, 2019Inventors: Wen-Hao YU, Chun-Chih KUO
