TFT Display VS OLED Display

A new form of display technology called Organic Light-Emitting Diode (OLED) is sweeping the display world today. Let’s take a look at what TFT display VS OLED display and how it stacks up to TFTs.

OLED display uses a light-emitting diode (LED) that features an organic compound as its emissive electroluminescent layer. Electric current is applied to the diode, activating the organic compound film and giving off light as a result. The organic compound film is typically situated between two electrodes, one of which is transparent.

OLEDs are mostly used in smartphones and limited releases of high-end smart televisions. It can also be used in computer monitors and handheld game consoles.

Now, here’s a comparison of TFT display vs OLED display:

Light Emission

OLED displays naturally emit light, so using them on a display panel doesn’t require a backlight. Meanwhile, LCDs need backlights because the liquid crystals cannot create light on their own. OLED’s natural light emission also paves the way for creating lighter screen devices than those using TFT LCD display.


LCD displays are brighter than OLED. This is due to the LCD’s use of backlights that can brightly light up the entire screen. While OLEDs emit good brightness levels from their light, they can never match the brightness that LCD backlights have.

Black Levels

OLED wins in the black levels feature. It’s because OLEDs can perfectly turn off a pixel, causing it to become completely black. LCDs can’t create perfect black screens even with their full-array local dimming feature. LCDs are also prone to blooming, where a bright part spoils the darkness of an adjacent black area.

Viewing Angle

OLED screens have better viewing angles than LCDs display. Some LCDs improve their viewing angles by using in-plane switching panels (IPS). However, the clarity of images and videos can’t match that of OLEDs when viewed from extreme side angles. This is because LCDs inherently block light due to their filtering layers, and that creates added depth which makes LCD viewing angles limited.

Energy Consumption

LCD displays are a bit more energy-efficient than OLEDs. Energy consumption in OLED displays depends on the screen brightness. Less brightness used means lower power consumption, but this may not be ideal because the contrast ratio will suffer when brightness is reduced. This is not ideal if, for instance, you’re using an OLED smartphone under bright sunlight.

Meanwhile, the backlights form the bulk of power consumption in TFT displays. Putting the backlight to a lower setting significantly improves the energy efficiency of TFT displays. For instance, reducing the backlight brightness of an LCD TV with a LED backlight won’t affect the picture quality but will draw less power consumption than an OLED TV.

Both OLED and LCD create high-quality images with a wide color gamut on a screen. OLED display wins over TFT display regarding blackness levels and viewing angle. However, the TFT display takes the cake for brightness and energy efficiency.

TFT Display VS AMOLED Display

AMOLED is another emerging display technology lately. It stands for Active Matrix Organic Light-Emitting Diodes. AMOLED is a type of OLED display used in several smartphones, digital cameras, televisions, and media players.

Active Matrix technology is utilized in AMOLED displays. This refers to how the OLEDs in the display panel are controlled and arranged.

Thin film transistors (TFTs) and capacitors are attached to each pixel LED component of the panel. At least two TFTs are attached to one pixel – one to control the capacitor’s charging and another to give a voltage source.

The voltage source allows continuous, constant current to the pixel. Hence, there is a better level of control exerted over pixels, allowing you to quickly dim or turn off and on individual pixels.

Let’s move on to a quick comparison of TFT display vs AMOLED display:

Color Accuracy

AMOLED displays have better color accuracy than LCDs. What makes the color more accurate in AMOLED displays is largely due to the precise pixel control achieved by AMOLED panels.

Whites and blacks appear perfect in AMOLED displays. Whites produced by LCDs may carry a bluish tint due to the backlight. Blacks don’t completely appear dark in LCDs, too.

Color Gamut

AMOLED provides a greater color gamut than LCDs. AMOLEDs (and all OLED displays in general) have additional blue and green saturation. While these hues greatly widen AMOLED’s color options, some people find the resulting colors a bit unnatural to look at.

Meanwhile, LCDs have subdued greens and quite compelling red hues. Its color gamut may not be as wide as AMOLED’s, but many people still find it satisfying. That’s because LCD’s color range closely matches the Standard RBG color gamut profile, the one most utilized in videos and images.

Color Balance

LCD’s backlights help maintain the color balance of the entire screen. The backlights ensure that color balance remains consistent across the display. Meanwhile, AMOLED tends to suffer from very slight color balance drifts because of variances in the diodes’ light-emitting capacity over time.

Contrast Ratio

LCDs often have a lower contrast ratio and are prone to light bleeds. That’s due to the backlights remaining open even if light has been blocked and the pixels are supposed to show black color. This is not a problem with AMOLED displays because the panel can simply switch off the pixel to create a pure black color. AMOLEDs have a better contrast ratio as exhibited by their pure black and white levels.

Component Lifespan

AMOLED’s different RGB components can degrade at different rates. Hence, AMOLED may experience problems and degradation at a faster rate than LCDs.

Suitability for Mobile Devices

Since AMOLED displays do not require filtering layers and backlights, they’re more suited for use in handheld mobile devices such as smartphones and gaming consoles. LCD may be used in mobile devices as well, but the filtering layers and backlights tend to add a slight bulk to the device. Hence, many manufacturers are now switching to thinner and lighter AMOLED displays.

To sum up this part, AMOLED displays fare better than LCDs in terms of color gamut, accuracy, contrast, and mobile device suitability. However, LCDs have the potential for longer lifespans and carry a better color balance across the display device.

Color LCD VS Display P3

Display P3 is an Apple-developed color space heavily used in American films and digital movie projection. It allows devices to display richer, vibrant, and more lifelike colors that are demanded in videos and movies. It’s also created for adapting to computer displays.

Display P3 has a color space based on the DCI-P3 primaries. It uses the D65 white point which is typically used in color spaces for computer displays. Display P3 also utilizes the sRGB transfer curve in place of the DCI-P3’s 1/2.6 pure gamma curve.

If you compare color LCD vs Display P3, you’ll find a significantly wider color range in Display P3 than the typical sRGB used in color LCDs. LCD monitors, especially those used in computers and laptops, are configured to accurately represent the sRGB gamut as precisely as possible. Meanwhile, Display P3 has been consistently used in Apple products since 2015, starting with the iMac desktop.

Display P3 is not limited to Apple devices, though. Several devices have been configured to support Display P3 as well. These include smartphones from Samsung, OnePlus, Google, and HTC. Even Windows-based laptops from Acer and Asus support Display P3 color gamut.


That’s all the basic information you need to know about LCD display screens. And the difference between TFT Display VS OLED Display. Now, you know How LCD Works, its possible lifespan, components, and how it compares to other display technologies.

Armed with this information, you can better appreciate and take care of your LCD display devices. And in case you’re planning to add display devices to your business, the information you’ve learned will help you make educated choices regarding the display technologies you’ll utilize.
