What are LCD and OLED mobile phone screens? What's the difference between the two?

As technology continues to advance, every amazing breakthrough will seem a little backward after a few years. boe 2023 Just like our mobile phone screens today, how could we think of a phone operating on a screen more than a decade ago may seem like a very normal thing now, but in addition to the continuous capability of the chip inside the phone, the screen is actually constantly evolving.

If LCD(liquid crystal display) is the surprising invention of flat panel display, then organic light-emitting diode (organic light-emitting diode) is the milestone of new technology. If you are a mobile phone lover, you must pay attention to the difference between LCD and organic light-emitting diode mobile phone screens.

When it comes to mobile phone screens, we have to introduce two kinds of screens, in addition to the LCD and OLED mobile phone screens mentioned above, BOE displays there is also a screen called "AMOLED", but AMOLED is OLED, the two are actually the same thing.

The general class of mobile phone screens

The difference between LCD and OLED screens

1. Different screen features

There is no doubt that LCD screens are more real, while organic light-emitting diode screens are more vivid, oled manufacturer and the two have a big difference in color performance.

2. The luminous principle is different

Liquid crystal displays produce light under the action of liquid crystal voltage, OLED is its own luminous characteristics.

3. Different screen materials

The LCD screen is made of inorganic materials, and the organic light-emitting diode screen is made of organic materials. They are made of different materials and have different life spans. In general, OLED screens have a shorter life.

The difference between LCD and OLED screens

What is LCD?

An LCD screen is a liquid crystal sandwiched between two pieces of glass. A colored fluorescent layer is arranged on the upper substrate, and a thin film fixed crystal is arranged on the lower substrate. The liquid crystal in the middle produces different light characteristics under the action of voltage, and finally produces different colors through the color light layer.

What is OLED?

A panel consisting of an organic light-emitting diode device, an organic light-emitting diode that emits light on its own, a thin coating of organic materials, and a glass substrate can emit light when an electric current passes through it, and the light can do the same in response to the current.

LCD screen advantages and disadvantages

LCD advantages

Longevity: lcds takes a long time to develop, so you don't have to worry about screen crashes. Chances are your other parts are broken, but the LCD is not, because it has a long life.

No flicker: The backlight of the LCD is a separate white LED backlight panel that does not flicker, so it protects the eyes.

Cheap: Because LCDS have been around for a while and costs have been kept under control, even better LCDS are not too expensive, especially compared to older displays.

LCD defects

Power consumption: Compared with OLED, LCD power consumption is much larger, may be OLED power consumption is too low, but compared with LCD this disadvantage is obvious.

Fingerprint recognition: Liquid crystal displays can not be fingerprint recognition, so it is easy to be eliminated by technology, because the fingerprint recognition function is very basic.

The thickness can not be too thick: mobile phones will be thinner and thinner, but the LCD screen is not thin, so it is really difficult for us to continue to see the LCD screen in the future of new technology.

OLED screen advantages and disadvantages

OLED advantages

Curved screen: OLED is the technology for foldable phones of the future.

Very thin and light: OLED because of its own luminous body, so we do not need to like LCD because of the use of two layers of glass, the natural material thickness is also very thin and light.

Brightness: The luminous mode of the organic light-emitting diode is that each pixel is independent, so it can be partially lit, rather than fully lit or fully lit like LCD.

More power saving: Also because of such a luminous way, so the power consumption is more advantageous.

Bright colors: The picture is much more delicate than the LCD screen, and the photos will be more beautiful.

OLED disadvantages

Flash: Due to the dimming mode of OLED, it is easy to produce visual fatigue.

Branding, color decay: OLED because of the relationship between the material, so there are life limits between Chinese pixels, think about whether the TV at home is used for a long time will have branding, that is one of the shortcomings of OLED screens.
