VEHICULAR DISPLAY APPARATUS AND OPERATING METHOD THEREOF

A vehicular display apparatus is provided. The vehicular display apparatus includes a driving device installed in a housing, a display module configured to move to an inner portion or an outer portion of the housing, based on a mechanical operation of the driving device, and a controller unit configured to control the mechanical operation of the driving device. The driving device includes a gear configured to move the display module to the inner portion or the outer portion of the housing and a light emitting sensor and a light receiving sensor facing each other with the gear therebetween. The light receiving sensor senses an optical signal of the light emitting sensor passing through a region between gear teeth of the gear, and the controller unit counts the number of gear teeth of the gear passing through a region between the light emitting sensor and the light receiving sensor on a basis of a sensing result of the light receiving sensor and controls movement of the display module, based on the counted number of gear teeth.
