OLED and LCD TVs are famous for displaying design screens. Yet, the OLED vs. LCD display comparison discusses numerous weaknesses and strengths when picking the appropriate display for your project. This comprehensive comparison article unravels the pros and cons of OLED vs. LCD to help you decide.
1. What is OLED and LCD?
OLED (organic light-emitting diode) screen describes an LED display option with an organic compound layer for emissive electroluminescent light. In general, the organic layer appears between two transparent electrodes, creating digital displays. OLED is common in smartphones, monitors, TVs, and game consoles.
LCD (liquid-crystal display) is an electric-modulated optical device that uses polarizers and liquid crystals. It doesn’t have light but uses a backlight to create images in monochrome color. LCDs display fixed images like clocks, digits, and preset words.
2. OLED Vs. LCD Specs Complete Comparison
OLED TVs create images using electric currents and an organic layer, while LCD screens pass light via a liquid crystal. In other words, the difference in images results in various OLED vs. LCD display differences in specs, such as image burn-in and lifespan. Other features include the viewing angle, brightness level, and contrast ratio.
Viewing Angles
Viewing angles impact image quality as you move away from your screen’s center and front view. Thus, you need a screen with a broader view angle to clean out the shadowy appearance. Organic light-emitting diodes feature a wider viewing angle since they are thinner, have no backlight, and have pixels closer to the surface.
Although OLED screens maintain readability and image quality from diverse angles, LCDs feature a smaller viewing angle. In other words, LCD images lose color from tilted viewing, but manufacturers install In-Plane Switching to improve results.
Brightness
OLED TV vs. LCD screens feature different brightness levels. Liquid-crystal displays feature LED backlight, while organic light-emitting diode TVs do not. OLEDs have better brightness since each pixel illuminates independently. Thus, OLEDs produce more brightness at the pixel level since they don’t rely on backlight.
Meanwhile, LCDs feature stable backlights illuminating the display to attain brighter images. Liquid-crystal displays produce more overall brightness than OLEDs. Yet, the backlight on LCD screens consumes more energy to produce fewer pixels.
Contrast
Contrast is the difference between an image’s darkest and lightest parts. Overall, high contrast generates more readable text and sharper images. LCD screens feature backlights to improve image and graphic visibility. Thus, liquid-crystal displays produce light even when the image is dark.
The organic light-emitting diode suits images with intricate details since it features higher contrast for more precise information. Each pixel shuts down completely where the image is black, rendering a higher contrast than LCD screens for better quality.
Lifespan
LCD lifespan extends to about 2,500 operation days, delivering quality images for up to seven years. Yet, you might observe dimming backlight over the period. On the other hand, organic light-emitting diode TVs have newer tech. They last up to 100,000 hours, running 10 hours daily for ten years.
Color Accuracy
LCD and OLED screens deliver excellent saturation and color accuracy. Yet, the organic light-emitting diode delivers better results. It can attain precise control of light emission for each image pixel. Hence, it can achieve deeper blacks and more vibrant colors. LCDs use the quantum dot tech to match OLEDs in color accuracy.
Energy Efficiency
Many reviews indicate that LCD TVs consume less energy overall than OLED screens when displaying white backgrounds and bright colors. Nonetheless, applications with black and dark images imply more energy consumption for the LCD as it lights the backlight. OLEDs require less energy to illuminate each pixel.
Working Principle
The organic light-emitting diode lies between a cathode and an anode on a substrate. Thus, the organic molecules can conjugate, resulting in pi electrons delocalization to conduct electricity. The organic semiconductor features LUMO and HOMO, the lowest and highest unoccupied molecular orbital that lights when in a complete circuit.
In the meantime, each LCD screen’s pixel features a molecule layer between transparent electrodes featuring polarizing filters and indium tin oxide. The liquid crystal lets light pass from the first filter to the second polarizer to light in an electric field.
3. OLED Display Advantages
OLED screens can be an excellent tech that generates precise and detailed images. The advantages of organic light-emitting diode screens include lower costs, lightweight structure, higher image quality, and response.
Response Time
OLED displays feature a faster response time than light crystal displays. Thus, they offer better refresh frequencies, faster color transition, and quick response time. However, modern LCD users can install response time compensation techs to improve speed.
Picture Quality
OLEDs feature a wider viewing angle and higher contrast ratio than LCDs since each pixel generates light independently. Hence, they can attain deeper black levels, ensuring perfect color with a viewing angle as high as 90° from the front.
Lightweight
The organic light-emitting diode has flexible plastic substrates or polyethylene terephthalate for reduced production costs and lower weight. Thus, it is a better option than LCD screens, which are prone to shattering because they use glass.
Lower Cost
OLED screens use cheaper materials than plasma and LCDs. The screens line up numerous substrate layers to ensure perfect image quality and detail accuracy. In addition, LCD screens can consume more energy due to their backlight feature.
4. LCD Display Advantages
Liquid-crystal displays (LCDs) are typical in automobiles, manufacturing, schools, offices, and homes. They are common in diverse industries since they are durable, have LED backlighting, experience no screen burn-in, and are suitable for small-size use.
Small Size Use
Liquid-crystal displays feature diverse sizes and shapes, including low-profile, narrow, small, and large screens. Thus, they deliver excellent results in devices such as tablets and smartphones. In addition, it enables manufacturers to attain complex small designs.
No Screen Burn-In
LCD screens do not grapple with screen burn-in since it happens to screens with phosphor-based pixels alone. LCDs generally use organic material pixels that do not struggle with burn-in. Thus, LCD can display a static image longer without burn-in.
LED Backlighting
The liquid-crystal display features LED backlighting, which manufacturers prefer because it is energy-efficient and more reliable. In other words, it comes with internal LED bulbs to illuminate the TV’s pixel back.
Long-Lasting
LCD TVs are long-lasting because they offer more durability than other screens. They can last up to 60,000 hours but vary depending on the application frequency. Thus, effective and regular service can help deliver results for up to 20 years.
5. OLED Display Disadvantages
The organic light-emitting diode can be a strategic investment for intricate museum design displays and video production. However, it has several drawbacks, such as a limited lifespan and poor color balance in some uses.
Color Balance
The material that generates blue light in OLED TVs degrades faster than materials for other colors. Thus, the blue light strength decreases over time, impacting other colors. This degradation reduces the overall screen’s light and impacts color output. Hence, the deterred color output impacts the overall color balance, reducing image quality.
Lifespan
The organic light-emitting diode degrades its luminance by 8% for green, 7% for red, and 12% for blue light within 1,000 hours. In other words, the blue shed delivers quality images for barely 14,000 hours. This degradation reduces the screen’s lifespan by half. Besides, the organic material develops dark spots due to moisture and oxygen ingress.
6. LCD Display Disadvantages
Liquid-crystal displays can be an excellent option for durability, LED backlighting, and no screen burn-in. However, the screen has several drawbacks, such as bad pixels and interference that deter performance. Here are more details.
Interference
LCD screens use analog light inputs that demand adjustments to pixel tracking to eliminate digital image noise. The automatic pixel control in LCDs delivers low-quality images. Thus, you must ensure careful adjustments for the timing drift and jitter during use. Some LCD screens do not eliminate all digital image noise.
Bad Pixel
Liquid-crystal screens feature stuck and weaker pixels that remain off or on throughout. Meanwhile, the pixels may be improperly connected to the columns, rows, and pixels. This improper installation may result in uneven shading and light intensity.
