Abstract
A display device includes a signal detector for detecting gradation pixel data input to a display having multiple pixels, a current detector for detecting currents supplied to at least part of the pixels included in the multiple pixels, and an output part for outputting current data corresponding to currents supplied to the part of the pixels and signal data corresponding to gradation pixel data used for the part of the pixels. Accordingly, it is possible to compare current data with signal data, and therefore, it is possible to confirm whether or not video signals are correctly displayed on a screen.
Claims14
A video monitoring method comprising:
- detecting gradation pixel data input to a display having a plurality of pixels;
- detecting a current supplied to part of pixels among the plurality of pixels;
- and
- outputting current data corresponding to the current supplied to the part of pixels and signal data corresponding to the gradation pixel data used for the part of pixels,
- wherein the signal data comprises addition data produced by adding the gradation pixel data and the gradation pixel data being delayed by one frame.
A display device comprising:
- a signal detector configured to detect gradation pixel data input to a display having a plurality of pixels;
- a current detector configured to detect a current supplied to part of pixels among the plurality of pixels;
- and
- an output part configured to output current data corresponding to the current supplied to the part of pixels and signal data corresponding to the gradation pixel data used for the part of pixels,
- wherein the signal data comprises addition data produced by adding the gradation pixel data and the gradation pixel data being delayed by one frame.
A display system comprising:
- a video transmission part configured to output a video signal;
- a signal detector configured to detect gradation pixel data included in the video signal input to a display having a plurality of pixels;
- a current detector configured to detect a current supplied to part of pixels among the plurality of pixels;
- and
- an output part configured to output current data corresponding to the current supplied to the part of pixels and signal data corresponding to the gradation pixel data used for the part of pixels,
- wherein the signal data comprises addition data produced by adding the gradation pixel data and the gradation pixel data being delayed by one frame.
