Abstract
A display may include a color filter layer, a liquid crystal layer, and a thin-film transistor layer. A camera window may be formed in the display to accommodate a camera. The camera window may be formed by creating a notch in the thin-film transistor layer that extends inwardly from the edge of the thin-film transistor layer. The notch may be formed by scribing the thin-film transistor layer around the notch location and breaking away a portion of the thin-film transistor layer. A camera window may also be formed by grinding a hole in the display. The hole may penetrate partway into the thin-film transistor layer, may penetrate through the transistor layer but not into the color filter layer, or may pass through the thin-film transistor layer and partly into the color filter layer.
