Display
Apple's display technology shone brightly with the Retina LTPO OLED screen, known for its vivid color accuracy and deep contrasts. The Series 4 had a 1.78-inch display with a resolution of 448 x 368 pixels, delivering a pixel density of approximately 326 pixels per inch. This ensured clarity and sharpness for reading texts and notifications. The screen's peak brightness level of 1000 nits allowed for exceptional visibility even in direct sunlight, adding to the convenience for outdoor use. The Sapphire crystal glass provided ample protection against scratches and everyday wear and tear.
