An established technology is TFT LCD. OLED is a comparatively new display technology that is increasingly being employed in many applications. A new generation of technology with a bright future is micro LED. The benefits and drawbacks of each display technology are listed below.
These days, TFT liquid crystal displays are commonly utilized. as LCD doesn't produce light on its own. White LED backlight is used by TFT LCD to display content. This describes the operation of a TFT LCD.
Long longevity and low cost: LCD is an established technology. Its life is longer than that of OLED.
White LED lighting on LCD uses DC power, therefore there is no stroboscopic effect. It won't result in a stroboscopic effect.
High pixel density: TFT LCD offers crisper images than OLED at the same resolution.
High power usage: TFT LCD requires backlight. Consequently, it is thicker and uses more energy.
comparatively less contrastPolarizers, color filters, polarizing LCD glasses, and liquid crystal layers all need to let light through. 90% or more is gone. Additionally, LCD cannot show a black screen.
An organic electroluminescent layer that comprises organic compounds that generate light in response to an electric current is the foundation of an organic light-emitting diode. OLEDs come in two varieties: passive matrix (PMOLED) and active matrix (AMOLED). These driving techniques resemble LCDs. PMOLED is progressively controlled using a matrix addressing system; to address a m x n display, m + n control signals are needed. AMOLED employs a TFT backplane that has the ability to turn on and off certain pixels.
OLED is lighter and thinner than LCD due to its ability to emit light.
Low power consumption and flexibility: OLED uses less electricity because it doesn't need a backlight. In essence, OLED is produced on plastic film. It can be processed easily and is flexible.
High contrast and vibrant color: Because OLEDs emit their own light, they may produce images that are both brilliant and colorful. Additionally, OLED may generate pure black since it can be turned off.
OLED's reaction time is faster than LCD's, and turning on and off an LED is quicker than twisting a liquid crystal display.
OLED may experience picture retention (burn-in) issues. After displaying a static image for a while, the pixels gradually deteriorate.
Most OLED screens employ PWM dimming technology, which creates a stroboscopic effect. Some individuals with a sensitivity to stroboscopic frequency may experience eye pain and tears.
Blue light-producing organic substance has a shorter lifespan. OLED color shifting and reduced lifetime are the results of this.
Micro LEDs, often known as "LED is made up of tiny LED," are less than 100 m in size. Another way to look at this is to say that MicroLEDs are just regular LEDs that have been compressed and arranged in an array.
Micro LED provides a much faster reaction time, higher brightness, a wider viewing angle, and a longer lifespan than TFT LCD and OLED.
Inorganic GaN material can take the place of biological material, doing away with the necessity for OLED's polarizing and encapsulating layers. Micro LEDs are thinner and smaller and use less energy.
Costly: The production of micro LEDs, a novel technology, is pricey.
Producing Micro LED is now quite challenging, as is the case with many new technologies.
