An electronic paper display apparatus including a display driving unit, an electronic paper display panel and a detection circuit unit is provided. The display driving unit generates at least one driving signal. The electronic paper display panel is coupled to the display driving unit. The display driving unit drives the electronic paper display panel to display an image by the at least one driving signal, and the electronic paper display panel outputs the at least one driving signal. The detection circuit unit is coupled to the electronic paper display panel to receive the at least one driving signal outputted by the electronic paper display panel, and detect a display status of the electronic paper display panel according to the at least one driving signal. Besides, a detection method of an electronic paper display apparatus is also provided.

Electronic paper display apparatus and a detection method thereof

A bi-stable display, frame updating method and timing sequence controlling method thereof are disclosed. The frame updating method of the bi-stable display includes the steps of comparing a difference of source driver output voltages of adjacent frames of image updating period with a preset threshold, and determining parameter value of each transitional state of the adjacent frames when the difference equal or greater than the preset threshold for controlling level of source driver output voltage. Accordingly, the effects such as signal interference, reduction of image quality resulted from switching between high voltage levels directly and rapidly and excessive power consumption may be eliminated.
