AMOLED and LCD displays are the two mainstream display technologies currently on the market. They have obvious differences, and these differences largely determine their application scenarios and advantages and disadvantages. Here are the differences between AMOLED and LCD displays.

First, AMOLED and LCD displays work differently. LCD display is a technology that uses the optical properties of liquid crystal materials to display images. With the aid of the backlight, it achieves the display effect by controlling the liquid crystal state of each pixel. AMOLED displays, on the other hand, are a technology that uses organic light-emitting diodes (OLEDs). It realizes the display effect by controlling the light-emitting state of the organic thin film of each pixel without a backlight source. As a result, AMOLED displays have higher contrast ratios and more vibrant colors.

Second, AMOLED and LCD displays differ in terms of energy consumption. Since an AMOLED display consumes power only when displaying black and hardly any other colors, it consumes relatively little power. The LCD display needs to consume energy all the time to maintain the brightness of the backlight, so the energy consumption is relatively high.

Third, AMOLED and LCD displays are also different in display effect. Because the screen of the AMOLED display is very thin, it has better viewing angles and a wider field of view. Although the LCD display also has a good viewing angle and field of view, due to the limitation of the structure of the liquid crystal panel, its thickness and screen distortion will have some influence.

Finally, the application scenarios of AMOLED and LCD displays are also different. Since AMOLED displays have higher contrast and more vivid colors, they are suitable for the display needs of consumer electronics, such as smartphones, tablets, TVs, etc. The LCD display is more suitable for professional fields, such as medical, military, industrial and other fields, because it can manufacture different structures and screen sizes according to specific needs.

In short, there are obvious differences between AMOLED and LCD displays in terms of working principle, energy consumption, display effect and application scenarios. For consumers, when purchasing electronic equipment, they need to choose a more suitable screen technology according to their specific needs and budget.
