RetinaHD displays have higher contrast, bichromatic pixels and better polarizers.
Higher contrast: better reading and browsing experience, darker and sharper text.
Bicolor domain pixels: wider viewing angle
Better polarizer: Even if you are wearing sunglasses, the RetinaHD monitor can let you see the content on the screen better.
Lcd (short for liquid crystal display) liquid crystal display. The structure of LCD is to place a liquid crystal box between two parallel glass substrates, a TFT (thin film transistor) on the lower substrate glass, and a color filter on the upper substrate glass. The rotation direction of liquid crystal molecules is controlled by the change of signal and voltage on TFT, so as to control whether the polarized light of each pixel is emitted or not, and achieve the purpose of display. LCD has replaced CRT as the mainstream, the price has dropped a lot, and it has been fully popularized.
