2. A glass-free stereoscopic image display method performed by a processor of a user device, comprising:
-
providing a stereoscopic image by controlling a left-eye image pixel and a right-eye image pixel of a display module of the user device, wherein the providing of a stereoscopic image comprises adjusting a rendering pitch of the display module on the basis of a viewing position of a user and a lens pitch, and controlling the display module on the basis of the rendering pitch so that an image displayed on the display module is converted into a stereoscopic image through a cover, which is provided on a front surface of the user device and including a lenticular lens, and then provided to a user, the rendering pitch indicates a distance between left-eye image pixels of the display module or a distance between right-eye image pixels of the display module, the lens pitch indicates a distance between multiple convex lenses included in the lenticular lens, the viewing position refers to a position where a right eye and a left eye of the user are placed. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12)

13. A glass-free stereoscopic image display device comprising:
-
a display module that displays a stereoscopic image through a cover including a lenticular lens including multiple convex lenses; and a processor that controls the display module, wherein the processor; measures a viewing position of an user for the glass-free stereoscopic image display device through a camera connected with the glass-free stereoscopic image display device, adjusts a distance between left-eye image pixels of the display module or a distance between right-eye image pixels of the display module, based on a lens pitch, which indicates a distance between the multiple convex lenses of the cover positioned at a front surface of the glass-free stereoscopic image display device, and the viewing position, provides a glass-free stereoscopic image by controlling a left-eye image pixel and a right-eye image pixel of the display module on the basis of the distance between left-eye image pixels of the display module or the distance between right-eye image pixels of the display module so that an image which occurs on the display module and passes through the cover is provided as the glass-free stereoscopic image for the user, the viewing position refers to a position where a right eye and a left eye of the user are placed.
