Abstract: A display system is provided, which may include a processor, a controller, a content checker and a display panel. The controller receives an input signal, and generates a video data according to the input signal and a plurality of timing signals according to the input signal. The content checker includes a first look-up table. The content checker compares the video data with the first look-up table, and transmits a report to the controller or the processer according to a comparison result. The display panel displays the video data according to the timing signals.

Abstract: A display system is provided, which may include a processor, a controller, a video combiner and a display panel. The controller receives a first input signal and a second input signal, generates a first control instruction and a second control instruction according to the first input signal and the second input signal respectively, and generates a first video data, a second video data, and a plurality of timing signals respectively according to the first control instruction and the second control instruction. The video combiner combines the first video data with the second video data to generate a combined video data. The display panel displays the combined video data according to the timing signals.

Abstract: A display system is provided, which may include a processor, a controller, a video combiner and a display panel. The controller can receive a first input signal and a second input signal from the processor, and can generate a first video data, a second video data and a plurality of timing signals according to the first input signal and the second input signal. The video combiner can combine the first video data and the second video data to generate a combined video data. The display panel can display the combined video data according to the timing signals.
