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.

Abstract: A display apparatus is disclosed. The display apparatus includes a LED module, a driving module and a control module. The driving module is coupled between the LED module and the control module. The LED module includes a plurality of package units. Each package unit includes a plurality of LEDs and at least one functional circuit. The driving module includes a conversion unit for receiving a first signal from the at least one functional circuit and converting it into a second signal. The control module controls the driving module to correspondingly change the operation of the LED module according to the second signal.
