What is the difference between OLED and LCD screens?
As technology is constantly evolving, so are the screens that we use in our portable devices. Particular technologies such as OLED and LCD are constantly evolving and becoming better. There are many differences and similarities between the two. They both have their advantages and disadvantages, and as a result, they both have their uses. Let‘s now take an in–depth look at the two different types of screens, how they work, and how they compare to one another.
OLED vs LCD technology
One of the most significant differences between OLED and LCD is how the screens work in each of them. LCD screens consist of a backlight that shines through the liquid crystals. This is done by using polarizing filters to control the light, which allows for the screen to be switched off or on. This technology is used in many types of screens including TVs and computer monitors. OLED screens, however, work differently. An OLED screen has pixels that are semi–conductors, meaning that they can conduct electrical charges. The organic light emitting diode (OLED) lights up and can be switched off at will. This makes it easy for the screen to display black pixels, making for an excellent contrast ratio. This is something that is very difficult to achieve with LCD screens, as they require a separate backlight to achieve darkness. When it comes to resolution, OLED screens can go up to 8K, while LCD maxes out at 4K. The amount of pixels on an OLED screen is also much higher than that of an LCD screen. On an OLED screen, the pixels are placed very close to each other, allowing for a much higher resolution. This is because the pixels produce their own light and do not require any backlight. However, while OLED screens can have a higher resolution than LCD screens, they are not as bright. OLED screens are also known to have color banding issues when displaying some darker colors. However, this is something that is constantly improving.
OLED vs LCD displays
When it comes to displays, OLED and LCD displays are very similar. They both have excellent contrast ratios and low response times. For LCD displays, however, the response time is dependent on the refresh rate of the screen. The refresh rate determines how often the image on the screen refreshes on a display with a 60Hz refresh rate. The response time on an LCD display is lower the lower the refresh rate is. On an OLED screen, the response time is dependent on the pixel switching time which is determined by the frame rate of the screen. The higher the frame rate, the lower the response time. In terms of color accuracy, OLED screens are much better than LCD screens. OLED screens are able to produce true pure colors while LCD screens often have a stuck between different colors in an image or video. An example of this is color banding when displaying darker colors. This is due to the fact that an LCD screen has a backlight that shines through its liquid crystals which makes it difficult to produce pure black colors. If you are looking for a screen that can produce high contrast images with true colors and a high resolution with amazing detail, then an OLED screen is perfect for you. If you are looking for a screen that can be viewed under bright sunlight easily then an LCD screen would be better suited for you.
How do they stack up to each other?
The advancements in OLED technology have led to many people thinking that these are superior screens over LCD displays. While this may be true in terms of color accuracy and high resolution, LCD displays are still better in some ways. When it comes to brightness level, especially in sunlight, LCD displays are still at the top of their game with their ultra–bright backlights. They still produce better contrast ratios than OLED displays as well as having lower response times when it comes to refresh rates. LCD displays still have lower color banding issues and better viewing angles compared to OLED displays as well as being thinner in nature compared to OLED displays which are known for being pretty thick due to their use of organic materials. According to reports, both technologies have their pros as well as their cons. However, in terms of durability, LCD displays are still more superior compared to OLED displays which can be broken easily if they are dropped or scratched in some way.
Overall, both LCD and OLED displays have their own advantages and disadvantages but have come leaps in recent years with improvements in technology to improve each other‘s weaknesses. With so much improvement in both OLED and LCD displays over recent years, you really can‘t go wrong with either of these technologies if you‘re looking for a good display for your phone or tablet device.
