A method for obtaining an incident angle θi is provided. The method is used in a panel having at least one icon, wherein the at least one icon has a plurality of protrusions, and a light-emitting source is disposed under the at least one icon. The method includes steps of obtaining a distance W between two centers of two bottoms of two trenches formed at two sides of one of the plurality of protrusions; obtaining a half of the distance W; obtaining a vertical distance H between the light-emitting source and a center of the distance W; and performing an inverse trigonometric function operation for the half of the distance W over the vertical distance H so as to obtain the incident angle θi.
