Describe the advantages and disadvantages of organic LED and LCD screens in detail so you can make a more informed decision.

When comparing organic light-emitting diodes (OLEDS) to traditional liquid crystal displays (LCDs), oled panels manufacturer the former has the ability to self-illuminate without a backlight and produces brighter colors while consuming less power. Advertisements often emphasize these advantages, implying that OLEDs are superior. However, LCDs continue to be available on the market for a reason. Despite its benefits, OLED technology also has significant limitations that prevent it from fully replacing LCDs or even acting as a "bridge" in screen history. It is important to examine these drawbacks in order to fully understand the role of OLED screens.

The advantages of organic LED screens - Introduction

As mentioned previously, OLED has the advantage of vivid colors and low power consumption, but why China?

In this regard, OLED screens are superior to LCD screens since they do not require a backlight

The LCD relies on a backlit LED for illumination, as its RGB pixels do not emit light. flexible OLED In contrast, OLED screens have self-emitting pixels and therefore do not require an LED backlight. This results in reduced power consumption, a thinner design, and darker black levels compared to LCDs (whose black is affected by the LED backlight). Additionally, the use of organic molecules in OLEDs allows for flexibility, unlike the rigid semiconductors used in LCD displays. As a result, many manufacturers prefer to use organic light-emitting diodes.

The disadvantages of organic light-emitting diodes

Branding and color decay:

The OLED screen will brand, due to the limitations of OLED material, OLED pixels have a limited service life, china oled with a long time will produce color decay, branding, such as ASUS Zenfone 3 Zoom that only uses AMOLED screens.

There are several brand areas on the screen, including QR codes and remote logos

The flash screen looks like this:

In organic light-emitting diodes, flickering is a low-frequency flicker. Although flickering is visually invisible, it can cause visual fatigue due to its dimming mode.

There are two types of dimming, which refers to adjusting the brightness of a screen

There are two types of dimming: DC dimming and PWM dimming

PWM dimming technology works by manipulating the pulse frequency or width to create the illusion of a darker or brighter screen for the viewer. However, this can result in a constant flickering effect which can cause fatigue for some individuals. OLED screens use PWM dimming, typically at a frequency of 200HZ, but since this method does not actually change the brightness, the screen may still appear very bright even when viewed directly. This is because our eyes perceive it as darker due to the blinking effect.

When DC dimming is used, the brightness of the screen is controlled by adjusting the voltage, but it has some disadvantages as well:

In order to adjust the brightness of high-grade LCD screens, some of our students use UHF PWM instead of DC dimming.
