Abstract
A display device and a display method are provided. The display device includes a board, a sensing circuit, and a feedback control circuit. The board includes a display array formed by a plurality of pixels. The sensing circuit includes a test pixel and a light sensor. The light sensor receives light emitted by the test pixel to generate a corresponding sensing signal. The feedback control circuit receives the sensing signal and generates a pulse width adjusting signal to adjust a pulse width at which the pixels are operated for display.
