LCD (Liquid Crystal Display) and OLED (Organic Light-Emitting Diode) are two display technologies commonly used today. LCD achieves its display by utilizing liquid crystals to emit light, whereas OLED can emit light on its own when electrically stimulated.

The main distinction between the two lies in their illumination methods. LCD requires a backlight to illuminate the screen, while OLED can generate light autonomously. As a result, OLED displays eliminate the need for external lighting components such as CCFL backlight modules and layers like TFT glass, C/F glass, and polaroid. These characteristics contribute to a simpler, lighter, and more energy-efficient structure compared to LCD displays.

In the full-screen era, OLED displays are more popular. And it also has something to do with the fingerprint recognition technology. For this technology need to penetrate the display, so the thinner display, the better it is. That’s why the OLED display is preferred. In a word, the OLED display is more suitable for smartphones.
