LCDvsOLEDReddit

Hence, in the low brightness status of the OLED, the screen off time is long, the black field interval become obvious, and the screen on and off (flickers) is noticeable by our naked eyes.

For your quick knowledge, we have recapped the key differences in the following table, then illustrate them in detail point by point.

As shown in the previous structure comparison, due to the existence of the backlight layer and liquid crystal layer, the LCD screen is thicker than the OLED.

Images on OLED will not be distorted from the sides and can maintain their quality and readability from nearly any angle. While the most common LCDs don’t.

The liquid crystal (LC) is placed between two conductive glasses, when power is applied, the electric field is created between two electrodes.

The full form of OLED is organic light-emitting diode, which is an organic self-luminous material that emits light by itself without the need for a separate backlight or color filter. Each OLED pixel can be assigned three colors red, green, and blue.

When the voltage is input, the anode current flows through the device, electron holes are formed. Meanwhile, the cathode injects electrons into the circuit.

The degree of opening (twist) of LC is controlled by adjusting the voltage input. When the opening is large, more light can pass through. Therefore, the amount and brightness of the light are controllable.

Compared with LCD, the OLED screen is a solid-state component, so it can perform better in anti-vibration and low-temperature resistance (normal low operation temperature is -40 ℃).

As to the LCD screen, normally it is hard to eliminate the smear, which is also affected by the temperature. The lower the temperature, the more serious the smear happens.

For the same reason, the flexibility of LCD is limited, it can only be bent to a certain angle. The curved screens of the desktop are LCDs, which are only bent to a small degree.

With the knowledge of how both display technology work and their structures, the differences in features can be easy to explain.

As in OLED, it is PWM (Pulse-Width Modulation) dimming, which means controlling the brightness by continuously switching on and off the screen at a certain high frequency till it is imperceptible by the naked eye.

As the nature of the liquid crystal layer cannot be fully closed, when the LCD panel displays black, some light will pass through the color layer. The black shown on the LCD screen is gray, a combination of white and black.

However, the PMOLED is still facing the problems of high power consumption and short lifespan. Currently, the common size of the display is limited to around 5-inch.

Even though the general cost of OLEDs is almost twice as much as LCD panels,  OLED panels are still popular in high-end TVs or flagship mobile phones, while LCD panels have occupied the largest share in the whole display market.

For example, if the 1080p LCD screen is replaced with an OLED screen, it is obvious to see the graininesses on the screen. But when the resolution reaches above 2k, this phenomenon is not obvious anymore.

Given the OLED screen is self-illuminating, when watching the screen in a dark environment, the light is strong, which causes more damage to the eyes than the light from LCD.

However, a new technology In-Plane Switching (IPS) has compensated for the drawback of LCD, the viewing angle of IPS LCD can even reach 170⁰.

However, due to the pixel arrangement of OLED, even if two screens have the same resolution, the clarity of the OLED screen will be lower than LCD.

At present, AMOLED is widely used in consumer electronics products and is the main OLED technology on the market application.

You may notice when tilting or viewing an LCD monitor from different angles, images become distorted or lose their colors.

OLEDvsLCDpower consumption

In comparison, in addition to light and thin features, OLEDs can be folded almost as freely as origami. The foldable smartphone is supported by OLED technology.

In the electric field effect, the nematic liquid crystal molecules will twist, which can block the light passing through, to control the transmission or shielding of the light source from the backlight.

Each pixel of OLED work individually, the pixels turn off and consume no power at all when displaying black and consume different energy while displaying different colors in different brightness.

According to the data from TrendForce, in 2021, the penetration rate of LCD panels in the smartphone industry is 58%, while AMOLED has caught up and reached 42%, as shown in figure 1.

In fact, in PWM dimming, the screen’s brightness is set and not changed. Instead, the lit time of the screen is changing, for example:

Because in a project, except for the technology features, there are still many things that need to be considered, like budget, supply resources, etc.

In screen brightness control, for LCD, it is usual to control the brightness directly by adjusting the voltage of the backlight (DC dimming).

When both meet in the organic light-emitting layer, they become excitons and release photons. Consequently, colors are displayed on the screen.

According to the data from Frost & Sullivan, in 2020, LCD is the absolute mainstream display panel technology, with shipments accounting for 96% of the global display market share.

In addition to the flicker phenomenon, OLEDs will cause more obvious irritation to the eyes and even the migraine after a long-time of watching.

Unlike LCD, when OLED displays black, the pixels in the black area can be directly turned off to achieve an almost pure black effect. In another word, In theory, OLEDs have an extreme contrast ratio.

If the time takes too long, the pixel will not have time to change from color A to color B when the screen is rapidly sliding. As a result, the image remains and the image smear appears visually.

OLEDvsLCDwhich is better for eyes

Given the assembly structure of the backlight layer to the LCD panel, it is a gap between the screen and the frame to a certain degree.

For example, on OLED TVs, burn-in happens on the blue pixels due to high frequent lighting. However, the white screen of OLED TVs will also change due to blue’s diminishing. If we compare the white screen every month, yellowish will be noticed.

In addition, the organic and self-emitting nature of OLED material is sensitive to humidity and oxygen concentration, resulting in some pixels degrading faster (decay period) than LCDs.

This driving mode is easier to achieve high brightness, high resolution, high color performance, and low energy consumption.

At present, given the technology developed more than 3 decades, LCD technology and supply chain is mature, and new technology and solution are still improving and introduced in the market to keep their advantage.

To adapt to various requirements in the market, different compensatory technologies keep introduced to the market, such as TFT and IPS.

Although the overall share of OLED is not large, due to its unique flexible feature, it can meet the needs of curved and foldable screens and is widely used in fashion and emerging electronic products with a small screen,  such as mobile, smart wearables, and VR devices.

In this article, we are trying to give you a complete guide to their comparison, so that you can understand their differences and then choose your suitable display technology.

Because, in the terminal usage, the working frequency of each pixel for different colors is unequal, in consequence, the diminution rate is inconsistent.

Therefore, the burn-in phenomenon inevitably happens on an OLED screen, more obviously on a big screen, and its average service lifespan is shorter than LCD.

Its simple structure is beneficial to the production process and cost management in manufacturing. With the fast response feature,  It has great development potential in microdevices for simple displays.

However, in 2022 SDI Display Week, Meta introduced their new generation VR headset Quest 2, which uses the fast switch LTPS LCD technology. The image persistence is low and almost not noticeable in VR game playing.

OLED technology is relatively new and in the developing stage, still has a long way to optimize the technology as well as the production processes and yield rate.

The OLED screen has almost no smear in normal usage except that the white text will produce the smear on a pure black background.
