Abstract

An electronic display apparatus comprises a lighting unit, a displacement detecting unit, a storage unit and a data processing unit. The lighting unit includes a plurality of light emitting elements aligned in a first direction. The displacement detecting unit is used for detecting displacement data of the electronic display apparatus in a second direction, where the second direction crosses to the first direction and an array area is defined between the first direction and the second direction. The storage unit is used to store a plurality of array image data. The data processing unit is used for receiving the displacement data forwarded from the displacement detecting unit and obtaining one of the array image data from the storage unit, which power of the light emitted by the light emitting elements is controlled according to the displacement data so as to display the array image data on the array area.
