Abstract
A display driver device (200, 920), a display driver method (900), and a display device (900) relating to the field of display technology. The display driver device (200, 920) comprises a display driver chip (210). The display driver chip (210) includes: a first register (212); a plurality of pins (211); and a processing circuit (213) configured to: write a duration of a first level of a gate trigger signal corresponding to display mode information into the first register (212), wherein the gate trigger signal jumps from the first level to a second level at an end time of the first level; generate the gate trigger signal based on the duration stored in the first register (212); detect a reference voltage corresponding to the duration; and output the gate trigger signal and the reference voltage through the plurality of pins (211).
