Abstract
A display driving device is provided, which can solve the problem of stripes occurring on a display panel when accompanied with a system, such as a notebook computer system, upon booting. The display driving device includes a single-channel pulse width modulation circuit, a boost-lowering voltage circuit, a delay circuit, and a display driver. An operation voltage signal for enabling pixels is provided to the display panel with a delay by the delay circuit, so that it is later than the logic operation voltage signal for powering the display driving device, the voltage signal for enabling the pixels and that for disabling the pixels. Thus, the above 'stripes' phenomenon can be eliminated.
