The viewfinder in the E-m10 mark II/III/IIIs/IV, Pen-F, and E-m5 mark III is an OLED viewfinder. The viewfinder in the E-m5 mark I/II, E-m1 mark I/II/II, E-m1x, Stylus-1, and the VF-2/VF-3/VF-4 viewfinders is a TFT LCD viewfinder. They have different characteristics:

In general an OLED viewfinder does not have issues if you look at the viewfinder while wearing polarized sunglasses and shooting in horizontal orientation. Most of the TFT LCD viewfinders have horizontal waves alternating between no distortion and heavy distortion (you can select the focus point if you concentrate on the areas where there is no distortion, but you would not be able to manually focus). However, the E-m5 mark II is different that when I"ve tried it, the viewfinder is completely opaque. Note, if you shoot in vertical orientation, there is not degradation.

In general, TFT viewfinders can refresh their images much faster that OLED displays can. I suspect this is the reason Olympus uses TFT viewfinders in the modern pro cameras.

Generally I find that the OLED viewfinder supersaturates the image compared to the TFT LCD viewfinder. This is great, many people like the supersaturation, but the picture that is recorded is not supersatured, and if you wanted the picture you saw in the viewfinder, you will need to bump up the levels somewhat in post processing.

In terms of computer monitors and TVs that use OLED displays compared to TFT LCD display, the OLED displays tend to fail sooner than the TFT displays. A particular failure mode is that often the OLED displays start losing color fidelity (particularly in the blue colors). However, I"m not sure it matters as much for a camera display. Most users probably don"t use their cameras enough for the monitor to fail. Those that do use their cameras day in and day typically replace their cameras every few years.

Also in terms of computer monitors and TVs that use OLED displays compared to TFT LCD displays, you can typically view an OLED screen at a wider angle than a TFT LCD screen. For a camera viewfinder, I suspect this is not an issue.

World wide, the cell phone market tends to consume most of the OLED displays. This leaves very few different displays that camera makers could use. TFT LCD display are older technology and there are likely different sources of the display.

I"m a migraine sufferer and I need to weark polarized sunglasses whenever I"m outdoors in daylight. So I now prefer cameras with OLED viewfinders over TFT LCD viewfinders.

I"ve run into other migraine sufferes that are sensitive to the refresh rate, but don"t need polarized glasses like I do. For them, the cameras with the TFT LCD finders are better because of the faster refresh rate.

TFT LCD is a mature technology. OLED is a relatively new display technology, being used in more and more applications. As for Micro LED, it is a new generation technology with very promising future. Followings are the pros and cons of each display technology.

TFT Liquid Crystal Display is widely used these days. Since LCD itself doesn"t emit light. TFT LCD relies on white LED backlight to show content. This is an explanation of how TFT LCD works.

Relatively lower contrast:Light needs to pass through LCD glasses, liquid crystal layer, polarizers and color filters. Over 90% is lost. Also, LCD can not display pure black.

Organic Light-Emitting Diode is built from an electro-luminescent layer that contains organic compounds, which emit light in response to an electric current. There are two types of OLED, Passive Matrix OLED (PMOLED) and Active Matrix OLED (AMOLED). These driving methods are similar to LCD"s. PMOLED is controlled sequentially using a matrix addressing scheme, m + n control signals are required to address a m x n display. AMOLED uses a TFT backplane that can switch individual pixels on and off.

Low power consumption and flexible: OLED doesn"t rely on backlight and consumes less power. OLED is essentially created on plastic film. It is bendable and easy to process.

High contrast and vivid color: OLED emits light itself, can produce very bright image with beautiful color. And because OLED can be turned off, it can produce true black.

Stroboscopic effect: most OLED screen uses PWM dimming technology. Some people who are easy perceive stroboscopic frequency may have sore eyes and tears.

​Micro LED, sometimes called μLED is made up of tiny LED, measure less than 100μm. Another way of looking at this is that MicroLEDs are simply traditional LEDs shrunk down and placed into an array.

Replacing organic material with inorganic GaN material eliminates the need of polarizing and encapsulation layer, found in OLED. Micro LED is smaller and thinner, consumes less power.

If you’re designing a display application or deciding what type of TV to get, you’ll probably have to choose between an OLED or LCD as your display type.

Not sure which one will be best for you? Don’t worry! We’re here to help you figure out the right display for your project or application. In this post we’ll break down the pros and cons of these display types so you can decide which one is right for you.

LCDs utilize liquid crystals that produce an image when light is passed through the display. OLED displays generate images by applying electricity to organic materials inside the display.OLED and LCD Main Difference:

These different technological approaches to display technology have big impact in some features including contrast, brightness, viewing angles, lifespan, black levels, image burn-in, and price.

Everything from the environment your display will be used in, your budget, to the lighting conditions and the required durability will play a part in this decision.

Contrast refers to the difference between the lightest and darkest parts of an image. High contrast will produce sharper images and more easily readable text. It’s a crucial quality for high fidelity graphics and images or to make sure that a message on a display is very visible.

graphics and images visible. This is the reason you’re still able to see light coming through on images that are meant to be dark on an LCD monitor, display, or television.

OLEDs by comparison, deliver a drastically higher contrast by dynamically managing their individual pixels. When an image on an OLED display uses the color black, the pixel shuts off completely and renders a much higher contrast than that of LCDs.OLED vs LCD - Who is better at contrast?

Having a high brightness level is important if your display is going to be used in direct sunlight or somewhere with high ambient brightness. The display"s brightness level isn"t as important if it’s going to be used indoors or in a low light setting.OLED vs LCD - Who is better at Brightness?

This means the display is much thinner than LCD displays and their pixels are much closer to the surface of the display, giving them an inherently wider viewing angle.

LCDs with IPS are significantly brighter than standard LCDs and offer viewing angles that are on-par with OLEDs.OLED vs LCD - Who is better at Viewing Angles?

LCDs have been on the market much longer than OLEDs, so there is more data to support their longevity. On average LCDs have proven to perform for around 60,000 hours (2,500) days of operation.

With most LCDs you can expect about 7 years of consistent performance. Some dimming of the backlight has been observed but it is not significant to the quality of the display.

OLEDs are a newer technology in the display market, which makes them harder to fully review. Not only does OLED technology continue to improve at a rapid pace, but there also hasn’t been enough time to thoroughly observe their performance.

You must also consider OLED’s vulnerability to image burn-in. The organic material in these displays can leave a permanent afterimage on the display if a static image is displayed for too long.

So depending on how your OLED is used, this can greatly affect its lifespan. An OLED being used to show static images for long periods of time will not have the same longevity as one displaying dynamic, constantly moving images.OLED vs LCD - Which one last longer?

There is not yet a clear winner when it comes to lifespans between LCD and OLED displays. Each have their advantages depending on their use-cases. It’s a tie!

For a display application requiring the best colors, contrast, and viewing angles – especially for small and lightweight wearable devices – we would suggest an OLED display.

Displays are a standard component of almost any device, application or machine. From the simple monochrome LCD character display used in portable testing equipment, to full colour graphic TFT screens used for infotainment, we have become well accustomed to the visual display of information and messages. Each area of application has specific requirements for its displays, and Telerex has a range of display technologies and product lines from trusted suppliers.

Both character and graphic LCD displays use only a moderate amount of electricity and take up only a moderate amount of space, and are therefore very suited to mobile applications on batteries. In TFT displays every pixel is directed by a tiny semiconductor that controls the amount of light that is allowed to pass through, which results in better resolution, contrast, and speed. With OLED displays a major step has been taken thanks to their very clear resolution, high contrast, wide viewing angle, and significantly lower power consumption. Finally, e-Paper displays provide the ideal solution for applications such as e-readers, interactive billboards, and interactive price tags in supermarkets, for which power consumption is critical and the display must remain static for a long period of time.

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.

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.

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.

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.

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.

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.

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.

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.

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 gamutmay 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.

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.

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.

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.

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.

Choosing a display is a crucial thing. If you consider 5 important display parameters in your selection and take the basic advantages and disadvantages of both technologies into account, you can easily choose the most suitable display for your application. This is an archive article published 04/01/2020. Some information may no longer be up to date and in line with the current state. Please contact us in case of interest.

Today, more and more applications are using the display. Whether as a means to display the desired information or as an interactive element (HMI- human-machine interface) with a touch panel.

1. Display demands on the performance of the host processor and application developmentClassic character displays with some of the standard controllers are the least demanding because the required content is displayed only on the basis of the codes sent - we do not care about the content of individual pixels. This also implies that the development of character display applications is the least difficult.

Monochrome graphical displaysare considerably more demanding on the host processor, but thanks to the integrated controller the control is relatively easy and modern controllers (together with the firmware from the manufacturer) make it possible to simplify application development significantly.

Previous statements about the demands on the host (master) controller as well as on the development/complexity of the application apply only to standard displays without added intelligence.

However, there are already a variety of display module families on the market that incorporate a powerful graphics processor and firmware, which along with the development software (that is almost always available for free) can significantly simplify the development of graphics applications. The performance of the used processors is in many cases also sufficient to control the surrounding components, so that the entire application can be built on the basis of the display module, without the need for an additional microcontroller.

Almost every display can now be fitted with a touch panel - resistive or capacitive. Even OLED industrial displays are already becoming available with touch panels.

Although the ease of control and perhaps the habit from smartphones tempts us to use a capacitive display, it is not optimal everywhere. The ability to operate the resistive panel even with normal gloves is still a big advantage. Still, the touch panel slightly worsens the contrast and brightness of the display, so if the brightness of the display is a priority, it is better to use the display without the touch panel.

The LCD display can be with or without backlight. The vast majority of available displays now have a backlight, allowing the display to be readable in darkness or dark environments.

However, under strong ambient light, and particularly in direct sunlight, the backlight is usually relatively dim, and the readability of the displays in the sun is significantly impaired. However, there are also exceptions where it is possible to maintain fair readability of the displays even in direct sunlight thanks to the technology used and the relatively powerful backlight.

OLED displays also suffer from significantly reduced contrast in direct sunlight, but some types provide acceptable readability even under such conditions.

It can be stated that there are several display technologies on the market, but the absolute majority of display types use some analogue of LCD (STN, FSTN, TFT, IPS ..) or OLED. Some advanced technologies - such as VFDs (vacuum fluorescent display) are still available but are only beneficial for some specific cases, like operation in frosts with low power consumption at the same time.

So, knowing that even a modern IPS TFT panel is still a liquid-crystal display in its essence, it implies one fundamental fact - its reaction times and usually the contrast and viewing angles have a significant effect on temperature changes. However, even in LCD technology, we can find types capable of working in the range of -30 ... + 85°C, but it should be taken in mind that the characteristics of the display at the limit temperatures will no longer be optimal.

When selecting a display, it is therefore important to consider the temperatures at which the display will work, and in addition to allowing the extraordinary temperature conditions that may occur in the application environment. To learn more about the effect of temperature on display life, see our article Check the limits of your display.

Although it may seem that OLED technology is a winner, let"s take a look at the current market situation for OLED displays suitable for industrial applications:

The price of OLED display is about 1.5-4x higher than the LCD alternative.Types available for industrial applications are almost exclusivelyPMOLED(passive matrix)OLED alternatives are already available for many classic character displays(2x16, 4x20, etc.), with characters of the same size and identical or very similar mechanical dimensions and pin layoutIn the vast majority of cases, only monochromatic OLEDs are available. Full-colour RGB versions are available only in small sizes - approx. 1.4 "-1.7".Larger sizes of RGB OLEDs (as we know them from today"s smartphones) are available only exceptionally and usually have a very short availability, so they are not suitable for devices manufactured for many yearsThe best readability and lifetime(electric) have yellow OLED; white colour is also quite good. This is also reflected in the market offer where green, blue and red are available on a significantly smaller scalePower consumption of a fully lit (all pixels) OLED display may be comparable or even higher than that of an LCD with backlight, but in practice, the entire display is rarely used, and so the OLED alternative consumption is usually lowerThe contrast and viewing angles are of course excellent, as we have already described in several of our articlesReadabilityof OLED in the sun is noticeably deteriorating and, although relatively acceptable, specialized LCDs (particularly transflective) can achieve better contrast in direct sunlight

The display market and manufacturers" offerings are evolving very quickly, but we can supply any display upon request, either in sample quantities or in mass quantities. Therefore, if you have not found a display suitable for your application in our range, do not hesitate to contact us.

LCD displays have been around for years, and changed the TV world to what we know now. Going back a few years, OLED panels were introduced and offered a better quality picture.

Here at AsTech Repairs, we want our customers to know what they are buying, we understand people these days really need to watch their spending, but at the same time, we believe the customer needs to know what they"re getting for their money. So here are the types of Displays typically avaliable for device repairs:

Cheaper / Older style technology. Quality of the image will be less than OLED. Uses a backlight panel which illuminates the full display, including content that is black. This differs from OLED.

With LCD, due to the construction, would be slightly thicker, so these types of displays would sit slightly higher than your OLED display (if your phone has OLED) and would be more prone to breaking.

Much better picture quality, but unfortunatley comes with a higher price tag. Due to the construction of OLED, each individual pixel is lit, so when viewing material with alot of black, thos "black pixels" are not actaully lit up, so should in return give you your optimum battery life. Picture quality is also much better, and this is where we also come across different types of OLED:

SOFT - Close to original as you can get for an aftermarket display, price - performance - quality, this would normally be one of the most popular choices. ( We prefer Soft OLED to Hard OLED screens and offer this when we quote for aftermarket)

HARD - Same quality, but the actual display behind the glass is not as flexible as the soft, so in turn, if these are dropped, the inner display can break without the top layer of glass breaking, even something as simple as knocking your phone while in your pocket could cause damage. ( We tend to not offer these screen types)

REFURBISHED - This is where a screen has been damaged on the top layer (glass only) so the glass is cut away, and the display is cleaned up with a new layer of glass applied. With this method, the original Apple display is kept, giving you one of the best quality after a brand new full genuine display replacement.

PULLED - Taken off another device. These displays are normally taken from devices that are stripped down due to other faults, so everything on the pulled display is 100% genuine, but would typically be one of the most expensive repairs. ​

In market, LCD means passive matrix LCDs which increase TN (Twisted Nematic), STN (Super Twisted Nematic), or FSTN (Film Compensated STN) LCD Displays. It is a kind of earliest and lowest cost display technology.

LCD screens are still found in the market of low cost watches, calculators, clocks, utility meters etc. because of its advantages of low cost, fast response time (speed), wide temperature range,  low power consumption, sunlight readable with transflective or reflective polarizers etc.  Most of them are monochrome LCD display and belong to passive-matrix LCDs.

TFT LCDs have capacitors and transistors. These are the two elements that play a key part in ensuring that the TFT display monitor functions by using a very small amount of energy without running out of operation.

Normally, we say TFT LCD panels or TFT screens, we mean they are TN (Twisted Nematic) Type TFT displays or TN panels, or TN screen technology. TFT is active-matrix LCDs, it is a kind of LCD technologies.

TFT has wider viewing angles, better contrast ratio than TN displays. TFT display technologies have been widely used for computer monitors, laptops, medical monitors, industrial monitors, ATM, point of sales etc.

Actually, IPS technology is a kind of TFT display with thin film transistors for individual pixels. But IPS displays have superior high contrast, wide viewing angle, color reproduction, image quality etc. IPS screens have been found in high-end applications, like Apple iPhones, iPads, Samsung mobile phones, more expensive LCD monitors etc.

Both TFT LCD displays and IPS LCD displays are active matrix displays, neither of them can produce color, there is a layer of RGB (red, green, blue) color filter in each LCD pixels to make LCD showing colors. If you use a magnifier to see your monitor, you will see RGB color. With switch on/off and different level of brightness RGB, we can get many colors.

Neither of them can’t release color themselves, they have relied on extra light source in order to display. LED backlights are usually be together with them in the display modules as the light sources. Besides, both TFT screens and IPS screens are transmissive, it will need more power or more expensive than passive matrix LCD screens to be seen under sunlight.  IPS screens transmittance is lower than TFT screens, more power is needed for IPS LCD display.
