With the continuous development and advancement of technology, mobile phone screens are also constantly innovating. Currently, mobile phone screens mainly include TFT-LCD, AMOLED, OLED, IPS, Super AMOLED and other types, among which LCD screens are relatively rare. So why are no current mobile phones suitable for LCD screens?

 

First, we need to understand what an LCD screen is.

 

LCD (liquid crystal display) is a device that uses electronic devices to adjust the transmission and blocking of liquid crystal. It consists of two transparent substrates with a liquid crystal layer sandwiched between them. This kind of liquid crystal molecules can be controlled by an electric field to change color and brightness.

Now let’s take a look at why today’s mobile phones are no longer suitable for LCD screens:

 

1. Screen quality

The display effect of the LCD screen is not as good as that of the OLED and AMOLED screens, and its contrast, display angle, and color reproduction are relatively average. Especially when viewed at low brightness, the black is not pure and is prone to light leakage, which will affect the visual experience.

 

2. Energy consumption

Compared with OLED and AMOLED screens, LCD screens consume higher energy because the light source needs to be reflected and filtered before it can be perceived by the retina. OLED and AMOLED screens illuminate directly through current and consume less energy.

 

3. Dimensions

As consumers have higher and higher requirements for display size, the size of LCD screens is limited. Since the LCD screen needs to reflect light and filter light, if the screen size is to be increased, more light sources are required, and the original display technology cannot be continued.

 

4. Flexibility

Nowadays, personalized customization is popular, and mobile phones with curved screens are also beginning to enter the market. The LCD screen is difficult to bend, which limits its application.

 

The above are the reasons why LCD screens are no longer suitable for modern mobile phones. The emergence of OLED and AMOLED technologies has more satisfied consumers' requirements for screens.

 

OLED technology is also called organic light-emitting diode technology. Unlike LCD, OLED is an organic film like small particles that emits light and does not require a backlight. This special structure allows OLED screens to achieve some advanced functions that existing technologies cannot accomplish, such as flexible and transparent screens and permanent display of lock screen screens. The display effect of the OLED screen is good, the colors are more vivid, the blacks are deeper, and the display effect is more realistic.

 

AMOLED technology is a branch technology of OLED. Its main feature is that the pixels can emit light. Compared with the commonly mentioned OLED screens, AMOLED screens have deeper blacks, higher brightness, lower battery energy consumption and longer life.

 

In addition, the AMOLED screen is very thin and can be bent freely on the device. It is also thinner and lighter, so it is suitable for devices of various sizes.

 

To sum up, OLED and AMOLED screens are more suitable for the needs of the modern mobile phone market than LCD screens. People's requirements for screens are constantly improving, and better technologies are used to meet consumer needs. This is also a manifestation of technological progress.

 

In short, with the continuous development of technology, mobile phone screens are also constantly changing and innovating. Currently, most mobile phone screens using OLED and AMOLED technology can better meet people's requirements for screen quality and viewing experience, so they may continue to have a larger market share in the future market.
