A driving device is used to control pixels of a pixel array. The driving device includes driving circuits. Each driving circuit includes a pulse width modulation circuit, which is used to provide an output pulse signal to at least one of the pixels of the pixel array, and a shift control circuit, which is used to provide a shift pulse signal to the pulse width modulation circuit and the shift control circuit of a next stage. The output pulse signal has an output pulse width. The shift pulse signal has a shift pulse width, which is substantially equal to a first period of a first clock signal or a second period of a second clock signal. The first period is equal to the second period. The pulse width modulation circuit modulates the output pulse width in response to the shift pulse signal, a data signal and a sweep signal.

A decoration panel includes a first substrate, a first transparent conductive element, a transparent structure, a second substrate, a second transparent conductive element, and a first cholesteric liquid crystal layer. The first transparent conductive element is disposed on the first substrate. The transparent structure is disposed on the first substrate. The second substrate is disposed opposite to the first substrate. The second transparent conductive element is disposed on the second substrate. The first cholesteric liquid crystal layer is disposed between the first transparent conductive element and the second transparent conductive element. A display apparatus is adapted to render a decoration pattern, and the decoration pattern corresponds to the transparent structure. Moreover, a display apparatus including the decoration panel is also provided.
