Are you familiar with mobile phone LCDs and organic light-emitting diodes?

Which component of a mobile phone holds the most value? While some may argue it’s the chip or memory, others believe it’s the camera. oled panels manufacturer However, contrary to popular belief, the most expensive part of a mobile phone is actually its screen. Since the launch of the iPhone X, Apple has been using OLED screens manufactured by Samsung in China. Each screen costs approximately 81 US dollars, thanks to the bulk discount provided to Apple. The two main types of mobile phone screens are LCD and OLED. But what are the pros and cons of each technology?

Liquid crystal displays are short for liquid crystal displays. To display LCDs, a backlight is needed, as the principle uses white light to produce different colors, the current controls the speed of light of each pixel to change the color of the pixels. As a result of years of development, this technology has become relatively mature. For example, TFT, IPS, and SLCD screens are basically LCD screens, but they are processed differently.

LCD screen operation

OLEDs are organic self-luminous materials that emit light without the need for a separate backlight technology or color filters. flexible OLED They are referred to as "Organic Light-Emitting Diodes" (Organic Light-Emitting Diodes). There are three colors to each OLED pixel information, red, green, and blue. Manufacturers are now adding yellow, but the principle remains the same.

Active OLEDs (AMOLEDs) and passive OLEDs (PMOLEDs) can be distinguished from OLED screens. The OLED screen we are discussing today is basically an AMOLED screen, and AMOLED itself is an OLED. With 95% of global production capacity accounted for by Samsung and LG, Samsung controls nearly all AMOLED technology.

An explanation of how OLED screens work

LCD screens have several advantages

The biggest advantage of LCD screens compared with OLED screens is low cost; LCD screen imaging effects are more natural, color restoration degree is higher; china oled LCD screen stroboscopic situation is better than OLED screen, the same resolution LCD display effect is more delicate; LCD screens last longer than OLED screens.

LCD screens have some disadvantages

It is a very difficult thing to achieve a full effect of white light display black, there will always be some leakage phenomenon more or less. LCD needs to be illuminated by the backlight for display.

Light leakage from LCD screens

LCD screen power consumption is higher, especially in the black background and OLED gap is larger, because the backlight is a whole, and even if there is just one light point in the entire black background, the backplane is completely bright, but the black part is blocked.

Having a backlight layer and a liquid crystal layer makes the LCD thicker than an organic light-emitting diode, so a thinner mobile phone is possible, which is consistent with modern people's desire for ultra-thin mobile phones.

Because the light from the fingerprint sensor penetrates the screen, some of the latest dark technologies, such as off-screen fingerprint recognition, can only be used on thinner OLED screens.

OLED screens have many advantages

When it comes to displaying black, organic light-emitting diode (OLED) screens have the unique ability to emit absolutely no light, resulting in a pure and true black color. Compared to LCD screens, OLED screens also have a wider color gamut and infinite contrast, making images appear brighter and more captivating. Additionally, OLED screens have a larger viewing angle and faster response speed than LCD screens.

Comparison of LCD and OLED screens

OLED pixels work independently of light, dark, extinguish, and LCD display no matter what color backlight is used, so the number of light screens can be greatly reduced, so OLED power consumption is much lower than LCD. OLED screens are therefore the only ones that can display the time under the breath screen.

The material of the OLED screen and cable is relatively soft and flexible, and the screen cable and IC chip can be bent behind the screen with the cof or cop process, so that the phone can get the effect of narrow chin. In addition to the now popular curved screen, organic light-emitting diodes have a unique feature as well.

Its self-luminous characteristics can easily identify fingerprints since OLED screens can achieve black technology such as fingerprint recognition under the screen.
