Abstract
A display device includes a display panel configured to display an image, the display panel including a first non-folding area; a second non-folding area; and a folding area disposed between the first non-folding area and the second non-folding area; and a window disposed on the display panel and including a folding portion overlapping the folding area of the display panel. The folding portion of the window includes a first substantially curved surface, a substantially flat surface extending from the first substantially curved surface; and a second substantially curved surface extending from the substantially flat surface.
Claims15
A method of manufacturing a window, comprising:
- providing a source substrate;
- forming a first preliminary substrate by etching the source substrate;
- and
- forming a second preliminary substrate by etching a portion of the first preliminary substrate, wherein
- the forming of the second preliminary substrate comprises:
- forming an etching paste on the portion of the first preliminary substrate;
- radiating heat having an uneven temperature gradient to the etching paste by using a lamp;
- and
- forming a first substantially curved surface, a substantially flat surface extending from the first substantially curved surface, and a second substantially curved surface extending from the substantially flat surface by etching the portion of the first preliminary substrate, wherein
- the lamp comprises multiple lamps that provide different temperatures from each other to produce the uneven gradient.
A method of manufacturing a display device, comprising:
- forming a display panel which includes a first non-folding area, a second non-folding area, and a folding area disposed between the first non-folding area and the second non-folding area, wherein the first non-folding area, the second non-folding area, and the folding area each include pixels;
- forming a window which include a folding portion comprising a first substantially curved surface, a substantially flat surface extending from the first substantially curved surface, and a second substantially curved surface extending from the substantially flat surface;
- and
- disposing the window on the display panel such that the folding portion of the window overlaps the folding area of the display panel, wherein
- the window includes a top surface and a bottom surface opposing the top surface, the window being disposed on the display panel such that the top surface faces away from the display panel, and
- the first substantially curved surface, the substantially flat surface, and the second substantially cured surface are etched in the top surface.
