is tft display easier to see in the sun for sale

When display devices are brought outside, oftentimes they face the brightness of sunlight or any other form of high ambient light sources reflecting off of and overwhelming the LED backlight’s image.

With the growth of the LCD panel industry as a whole, it has become more important than ever to prevent the sun’s wash out of displays used outdoors, such as automobile displays, digital signage, and public kiosks. Hence, the sunlight readable display was invented.

One solution would be to increase the luminance of the TFT LCD monitor’s LED backlight to overpower the bright sunlight and eliminate glare. On average, TFT LCD screens have a brightness of about 250 to 450 Nits, but when this is increased to about 800 to 1000 (1000 is the most common) Nits, the device becomes a high bright LCDand a sunlight readable display.

Doing this is an affordable option for enhancement of image quality in the outdoors, including features like contrast ratio and viewing angle, in a common use setting like with phones.

Since many of today’s TFT LCD display devices have shifted to touchscreens, the touch panels on the surface of LCD screens already block a small percentage of backlighting, decreasing the surface brightness and making it so that the sunlight can even more easily wash out the display. Resistive touch panels use two transparent layers above the glass substrate, but the transparent layers can still block up to 5% of the light.

In order to optimize the high brightness of the backlight, a different type of touchscreen can be used: the capacitive touchscreen. Though it is more expensive than the resistive touch screen, this technology is more ideal for sunlight readable displays than the resistive due to its usage of a thinner film or even in-cell technologies rather than two layers above the glass of the display, and therefore, light can pass more efficiently.

However, with this method comes a list of potential problems. Firstly, high brightness displays result in much greater power consumption and shorter battery life. In order to shed more light, more power will be needed which can also consequently result in device overheating which can also shorten battery life. If the backlight’s power is increased, the LED’s half-life may also be reduced.

While in bright exterior light settings, these devices reduce eye strain as the user attempts to view the image on screen, the brightness of the display itself can also cause eye strain, seen as the brightness may overwhelm your eyes. Many devices allow the user to adjust brightness, so this concern is oftentimes not too severe.

A recent technology falling into the sunlight readable display category is the transflective TFT LCD, coming from a combination of the word transmissive and reflective. By using a transflective polarizer, a significant percentage of sunlight is reflected away from the screen to aid in the reduction of wash out. This optical layer is known as the transflector.

In transflective TFT LCDs, sunlight can reflect off the display but can also pass through the TFT cell layer and be reflected back out off a somewhat transparent rear reflector in front of the backlight, illuminating the display without as much demand and power usage from the transmissive nature of the backlight. This addresses both the issues of wash out and the disadvantages of high brightness TFT LCDs in high ambient light environments. Because of its transmissive and reflective modes, this type of device is very useful for devices that will be used outdoors but also indoors.

While it does greatly reduce power consumption, transflective LCDs are much more expensive than high brightness LCDs. In recent years, the cost has decreased, but transflective LCDs continue to be more costly.

In addition to adjustments to the internal mechanics of LCDs, it is possible to make devices more sunlight-readable using surface treatments. The most common are anti-reflective (A/R) films/coatings and anti-glare processing.

Anti-reflective focuses on depositing multiple transparent thin film layers. With the thicknesses, structures, and properties of each individual layer composing the film, reflecting light wavelengths are changed, and thus less light is reflected.

When anti-glare is used, reflected light is fragmented. Using a rough surface as opposed to a smooth one, anti-glare treatments can reduce the reflection’s disruption of the actual image of the display.

Often paired with other methods of creating sunlight readable displays is optical bonding. By gluing the glass of a display to the TFT LCD cells beneath it, optical bonding eliminates the air gap that traditional LCD displays have in them using an optical grade adhesive.

This adhesive reduces the amount of reflection between the glass and LCD cell as well as the reflection of external ambient light. Doing this helps provide a clearer image with an increased contrast ratio, or the difference in the light intensity of the brightest white pixel color and darkest black pixel color.

With this contrast ratio improvement, optical bonding addresses the root issue with unreadable outdoor displays: the contrast. Though an increase in brightness can improve contrast, by fixing the contrast itself, LCD display images in outdoor environments will not be as washed out and will require less power consumption.

Besides the visual display advantages that optical bonding provides, this adhesive improves the display in many other ways. The first being durability, optical bonding eliminates the air gap within the device and replaces it with a hardened adhesive that can act as a shock absorber.

Touch screens with optical bonding gain, accuracy in where the point of contact is between the touch and screen. What is known as parallax, the refraction angle of light, can make it seem that the point of contact and the actual point on the display are different. When the adhesive is used, this refraction is minimized, if not reduced.

The optical bonding adhesive’s elimination of the air gap also protects the LCD from moisture/fogging and dust, as there is no space for impurities to penetrate and remain under the glass layer. This especially helps with maintaining the state of LCDs in transport, storage, and humid environments.

Compiling the various methods of improving LCD screens for sunlight readability, these devices can be optimized in high ambient light settings. An anti-glare coating is applied to the surface of the glass and anti-reflective coatings are applied to both the front and back. The transflector is also used in front of the backlight. These features can result in 1000 Nit or more display lighting, without the excessive power consumption and heat production through a high brightness backlight, consequently allowing for a longer lasting and better performing LCD

Unfortunately, the process of building a reflector inside TFT LCD is complicated and transflective TFT LCD is normally several times higher cost compared with normal transmissive TFT LCD.

To further improve and enhance the qualities of the LCD, LED and cold cathode fluorescent lamp (CCFL) backlights are used. Both these create bright displays, but the LED specifically can do so without as much power consumption and heat generation as compared to the CCFL option. Optical bonding is also applied in order to improve display contrast, leading to a more efficient and better quality sunlight readable display.

TFT (Thin Film Transistor) LCD (Liquid Crystal Display) we are talking here is TN (Twisted Nematic) type TFT displays which is align with the term in the TV and computer market. Now, TFT displays have taken over the majority of low-end color display market. They have wide applications in TV, computer monitors, medical, appliance, automotive, kiosk, POS terminals, low end mobile phones, marine, aerospace, industrial meters, smart homes, consumer electronic products etc. For more information about TFT displays, please visit our knowledge base.

Talking about Pros and Cons of TFT displays, we need to clarify which display they are compared to. To some displays, TFT displays might have advantages, but compared with another display, the same character might become the disadvantages of TFT displays. We will try our best to make clear as below.

Less Energy Consumption: Compared with CRT(Cathode-Ray Tube) VFD ( Vacuum Fluorescent Display) and LED (Light Emitting Diode) display, which made laptop possible.

Excellent physical design. TFT displays are very easy to design and integrated with other components, such as resistive and capacitive touch panels (RTP, CTP, PCAP) etc.

Minimum Eye Strain: Because TFT panel itself doesn’t emit light itself like CRT, LED, VFD. The light source is LED backlight which is filtered well with the TFT glass in front for the blue light.

More Energy Consumption: Compared with monochrome displays and OLED (PMOLED and AMOLED) display, which makes TFT displays less attractive in wearable device.

Poor response time and viewing angle: Compared with IPS LCD displays, AMOLED displays and recent micro-LED display. TFT displays still need to note viewing angle of 6 o’clock or 12 o’clock in the datasheet and still have the gray scale inversion issue.

High tooling cost: Depending on which generation production line to produce and also depending on its size. Building a TFT display fab normally need billions of dollars. For a big size display which needs high generation production line to produce. The NRE cost can be millions dollars.

Sunlight Readability: Because it is very expensive to produce transflective TFT LCD displays, in order to be readable under the sunlight, very bright LED backlight (> 1,000 nits) has to be used. The power needed is high and also need to deal with heat management. If used together with touch panel, expensive optical bonding (OCA or OCR) and surface treatment (AR, AF) technologies have to be used.

degrees. So, in this range we are safe, we can go very low with the temperature, and it will not become solid, and we can go very high with the temperature up to 110 degrees and it will not become isotropic.

Maybe you have even seen some displays that were used outdoors and sometimes they become black. We call that the blackening effect. If they become black, that means the crystals become isotropic. You can sometimes see that the part of the display is black or sometimes the whole display becomes black, depending on the temperature. The good thing is that it is not damaging the display, so once the temperature drops it goes back to the nematic phase and the display is working again, but in a high temperature you cannot see anything on the display, it is not working.

On the picture above, we have an example from a data sheet of a display with high temperatures. As we said it’s a liquid crystal from -40 to +110 degrees, and this is the latest technology. But you need to be careful! This is only about the surface of a display, the TFT glass itself. If we have the sunlight going to the display it can increase the temperature of the whole display as a module.

For the whole display module, the operating temperature range can be as low as 0 to +50 degrees or -20 to 70 degrees. We can have two operating temperatures, that means if we use the display outdoors, we are safe from the sunlight, the surface of the display can go very high, but we need to control the ambient temperature inside the display housing to not go too high. +50 or +70 will be maximum, usually we need fans to remove the heat from inside. Typically, in our case we have a computer inside and we have more devices that cannot work at high temperatures like +100 degrees, so we control the temperature anyway. So, the temperature cannot be too high inside and for sure cannot be that high as a liquid crystal itself can withstand, which is +110 degrees.

And that will be all in this article about contrast, brightness, and temperatures. Just one more thing: if you are planning on buying a laptop today, you can find brightness in the specification. Look at this number because this will determine how good your laptop will be outdoors. There are laptops on the market today that will have 1000 candelas or even more. If you are looking for a new device my recommendation also goes for mobile phones. Low brightness mobile phones can have 300, maybe 500 candelas, but nowadays the standard will be around 1000 candelas, but there are phones on the market that already have 1500 or even 1800 candelas. That means if you are in the sunlight you will still be able to see the image clearly. Of course, the battery will be drained faster, but sometimes it is not so important, maybe you just want to check something quickly, to read something and you want to have a clear image just be aware that this number is pretty important when you buy new devices!

Before you get a new monition for your organization, comparing the TFT display vs IPS display is something that you should do. You would want to buy the monitor which is the most advanced in technology. Therefore, understanding which technology is good for your organization is a must. click to view the 7 Best Types Of Display Screens Technology.

Technology is changing and becoming advanced day by day. Therefore, when you are looking to get a new monitor for your organization, LCD advantages, and disadvantage,  you have to be aware of the pros and cons of that monitor. Moreover, you need to understand the type of monitor you are looking to buy.

Now, understanding the technology from the perspective of a tech-savvy person may not be the ideal thing to do unless you are that tech-savvy person. If you struggle to understand technology, then understanding it in a layman’s language would be the ideal thing to do.

That is why it is important to break it down and discuss point by point so that you can understand it in a layman’s language devoid of any technical jargon. Therefore, in this very article, let’s discuss what exactly TFT LCDs and IPS LCDs are, and what are their differences? You will also find out about their pros and cons for your organization.

The word TFT means Thin-Film-Translator. It is the technology that is used in LCD or Liquid Crystal Display. Here you should know that this type of LCD is also categorically referred to as active-matrix LCDs. It tells that these LCDs can hold back some pixels while using other pixels. So, the LCD will be using a very minimum amount of energy to function. TFT LCDs have capacitors and transistors. These are the two elements that play a key part in ensuring that the display monitor functions by using a very small amount of energy without running out of operation.

Now, it is time to take a look at its features that are tailored to improve the experience of the monitor users significantly. Here are some of the features of the TFT monitor;

The display range covers the application range of all displays from 1 inch to 40 inches as well as the large projection plane and is a full-size display terminal.

Display quality from the simplest monochrome character graphics to high resolution, high color fidelity, high brightness, high contrast, the high response speed of a variety of specifications of the video display models.

No radiation, no scintillation, no harm to the user’s health. In particular, the emergence of TFT LCD electronic books and periodicals will bring humans into the era of a paperless office and paperless printing, triggering a revolution in the civilized way of human learning, dissemination, and recording.

It can be normally used in the temperature range from -20℃ to +50℃, and the temperature-hardened TFT LCD can operate at low temperatures up to -80 ℃. It can not only be used as a mobile terminal display, or desktop terminal display but also can be used as a large screen projection TV, which is a full-size video display terminal with excellent performance.

The manufacturing technology has a high degree of automation and good characteristics of large-scale industrial production. TFT LCD industry technology is mature, a mass production rate of more than 90%.

It is a perfect combination of large-scale semiconductor integrated circuit technology and light source technology and has great potential for further development.

TFT LCD screen from the beginning of the use of flat glass plate, its display effect is flat right angles, let a person have a refreshing feeling. And LCDs are easier to achieve high resolution on small screens.

The word IPS refers to In-Plane-Switching which is a technology used to improve the viewing experience of the usual TFT displays. You can say that the IPS display is a more advanced version of the traditional TFT LCD module. However, the features of IPS displays are much more advanced and their applications are very much widespread. You should also know that the basic structure of the IPS LCD is the same as TFT LCD if you compare TFT LCD vs IPS.

As you already know, TFT displays do have a very quick response time which is a plus point for it. But, that does not mean IPS displays a lack of response time. In fact, the response time of an IPS LCD is much more consistent, stable, and quick than the TFT display that everyone used to use in the past. However, you will not be able to gauge the difference apparently by watching TFT and IPS displays separately. But, once you watch the screen side-by-side, the difference will become quite clear to you.

The main drawback of the TFT displays as figured above is the narrow-angle viewing experience. The monitor you buy for your organization should give you an experience of wide-angle viewing. It is very much true if you have to use the screen by staying in motion.

So, as IPS displays are an improved version of TFT displays the viewing angle of IPS LCDs is very much wide. It is a plus point in favor of IPS LCDs when you compare TFT vs IPS. With a TFT screen, you cannot watch an image from various angles without encountering halo effects, blurriness, or grayscale that will cause problems for your viewing.

It is one of the major and remarkable differences between IPS and TFT displays. So, if you don’t want to comprise on the viewing angles and want to have the best experience of viewing the screen from wide angles, the IPS display is what you want. The main reason for such a versatile and wonderful viewing angle of IPS display is the screen configuration which is widely set.

Now, when you want to achieve wide-angle viewing with your display screen, you need to make sure it has a faster level of frequency transmittance. It is where IPS displays overtake TFT displays easily in the comparison because the IPS displays have a much faster and speedier transmittance of frequencies than the TFT displays.

Now the transmittance difference between TFT displays and IPS displays would be around 1ms vs. 25ms. Now, you might think that the difference in milliseconds should not create much of a difference as far as the viewing experience is concerned. Yes, this difference cannot be gauged with a naked eye and you will find it difficult to decipher the difference.

However, when you view and an IPS display from a side-by-side angle and a TFT display from a similar angle, the difference will be quite evident in front of you. That is why those who want to avoid lagging in the screen during information sharing at a high speed; generally go for IPS displays. So, if you are someone who is looking to perform advanced applications on the monitor and want to have a wider viewing angle, then an IPS display is the perfect choice for you.

As you know, the basic structure of the IPS display and TFT displays are the same. So, it is quite obvious that an IPS display would use the same basic colors to create various shades with the pixels. However, there is a big difference with the way a TFT display would produce the colors and shade to an IPS display.

The major difference is in the way pixels get placed and the way they operate with electrodes. If you take the perspective of the TFT display, its pixels function perpendicularly once the pixels get activated with the help of the electrodes. It does help in creating sharp images.

But the images that IPS displays create are much more pristine and original than that of the TFT screen. IPS displays do this by making the pixels function in a parallel way. Because of such placing, the pixels can reflect light in a better way, and because of that, you get a better image within the display.

As the display screen made with IPS technology is mostly wide-set, it ensures that the aspect ratio of the screen would be wider. This ensures better visibility and a more realistic viewing experience with a stable effect.

As you already know the features of both TFT and IPS displays, it would be easier for you to understand the difference between the two screen-types. Now, let’s divide the matters into three sections and try to understand the basic differences so that you understand the two technologies in a compressive way. So, here are the difference between an IPS display and a TFT display;

Now, before starting the comparison, it is quite fair to say that both IPS and TFT displays have a wonderful and clear color display. You just cannot say that any of these two displays lag significantly when it comes to color clarity.

However, when it comes to choosing the better display on the parameter of clarity of color, then it has to be the IPS display. The reason why IPS displays tend to have better clarity of color than TFT displays is a better crystal oriental arrangement which is an important part.

That is why when you compare the IPS LCD with TFT LCD for the clarity of color, IPS LCD will get the nod because of the better and advanced technology and structure.

IPS displays have a wider aspect ratio because of the wide-set configuration. That is why it will give you a better wide-angle view when it comes to comparison between IPS and TFT displays. After a certain angle, with a TFT display, the colors will start to get a bit distorted.

But, this distortion of color is very much limited in an IPS display and you may see it very seldom after a much wider angle than the TFT displays. That is why for wide-angle viewing, TFT displays will be more preferable.

When you are comparing TFT LCD vs. IPS, energy consumption also becomes an important part of that comparison. Now, IPS technology is a much advanced technology than TFT technology. So, it is quite obvious that IPS takes a bit more energy to function than TFT.

Also, when you are using an IPS monitor, the screen will be much larger. So, as there is a need for much more energy for the IPS display to function, the battery of the device will drain faster. Furthermore, IPS panels cost way more than TFT display panels.

1. The best thing about TFT technology is it uses much less energy to function when it is used from a bigger screen. It ensures that the cost of electricity is reduced which is a wonderful plus point.

2. When it comes to visibility, the TFT technology enhances your experience wonderfully. It creates sharp images that will have no problems for older and tired eyes.

1. One of the major problems of TFT technology is that it fails to create a wider angle of view. As a result, after a certain angle, the images in a TFT screen will distort marring the overall experience of the user.

Although IPS screen technology is very good, it is still a technology based on TFT, the essence of the TFT screen. Whatever the strength of the IPS, it is a TFT-based derivative.

Finally, as you now have a proper understanding of the TFT displays vs IPS displays, it is now easier for you when it comes to choose one for your organization. Technology is advancing at a rapid pace. You should not be surprised if you see more advanced display screens in the near future. However, so far, TFT vs IPS are the two technologies that are marching ahead when it comes to making display screens.

STONE provides a full range of 3.5 inches to 15.1 inches of small and medium-size standard quasi TFT LCD module, LCD display, TFT display module, display industry, industrial LCD screen, under the sunlight visually highlight TFT LCD display, industrial custom TFT screen, TFT LCD screen-wide temperature, industrial TFT LCD screen, touch screen industry. The LCD module is very suitable for industrial control equipment, medical instruments, POS system, electronic consumer products, vehicles, and other products.

This TFT display module includes a vibrant 5" TFT display mounted on an accelerated graphics embedded video engine (EVE) board. The EVE chip simplifies the creation of a beautiful user interface by leveraging FTDI/Bridgetek"s development tools.

The included 5" TFT display is a beauty. It is sunlight readable (1,000 nits), IPS, and 16M colors. That means whatever you want to display will be visible in most lighting conditions and from wide angles.

The board on this TFT module does some heavy lifting. A 30-pin ZIF / FFC connector brings in all the necessary signals for the display. The board boosts up the input voltage (3.3 to 5 volts) to power the backlight, and the included EVE chip can control the backlight, display, and audio. Plus, with six threaded mounts (size 2-56), securing this module in your project is easy.

I have the same question as Pieter. From the ST7282 datasheet, it is not possible to send any commands or change any registers without using the serial interface, and that serial interface is not provided on the 40-pin flex.

Even if this is true, there are still ST7282 registers that users might want to change. For example, on pages 39-40 of the datasheet, I see registers for setting brightness, contrast, and gamma. These will not be accessible.

Is there a demo of this display to prove that it actually works? Because leaving out the serial interface seems like it might have been a mistake made by the designers. I just want to make sure that this module actually functions.

> Regarding the software part,there is no need to make the setting for any registers as all of them are default value and doesn"t support to change, you just need to make the setting for VSYNC,HSYNC,DCLK Period, DCLK Frequency in your initialization code and you could get the parameters from ST7282 datasheet page 60.

IPS (In-Plane Switching) lcd is still a type of TFT LCD, IPS TFT is also called SFT LCD (supper fine tft ),different to regular tft in TN (Twisted Nematic) mode, theIPS LCD liquid crystal elements inside the tft lcd cell, they are arrayed in plane inside the lcd cell when power off, so the light can not transmit it via theIPS lcdwhen power off, When power on, the liquid crystal elements inside the IPS tft would switch in a small angle, then the light would go through the IPS lcd display, then the display on since light go through the IPS display, the switching angle is related to the input power, the switch angle is related to the input power value of IPS LCD, the more switch angle, the more light would transmit the IPS LCD, we call it negative display mode.

The regular tft lcd, it is a-si TN (Twisted Nematic) tft lcd, its liquid crystal elements are arrayed in vertical type, the light could transmit the regularTFT LCDwhen power off. When power on, the liquid crystal twist in some angle, then it block the light transmit the tft lcd, then make the display elements display on by this way, the liquid crystal twist angle is also related to the input power, the more twist angle, the more light would be blocked by the tft lcd, it is tft lcd working mode.

A TFT lcd display is vivid and colorful than a common monochrome lcd display. TFT refreshes more quickly response than a monochrome LCD display and shows motion more smoothly. TFT displays use more electricity in driving than monochrome LCD screens, so they not only cost more in the first place, but they are also more expensive to drive tft lcd screen.The two most common types of TFT LCDs are IPS and TN displays.

I"m not really building a carputer though, I"ve built a carputer before many years ago (I think around 2004/2005!) which worked really well for many years. It was a windows XP computer in small aluminium case connected to a 8" touch screen TFT display which I fibre glassed into a replacement dash panel that I got from the scrap yard. I ran some carputer software that booted directly without showing windows, and used a serial port pin raised and lowered by a startup script to trigger my audio amplifiers to come on after the computer had booted. It had GPS, wifi, 3G internet and a 1500w sound system wired up to it so it worked as an internet radio, had a all of my music in an easy to use touch jukebox and worked really nicely!

The TFT wasn"t a major problem but then again it was a tin-top car so not so much light around. You can buy lots of different displays which are good for in-car use from carputer component websites (you even could back then!)

What I"m doing is slightly different. I"m building an integrated dash pod to incorporate an analogue looking rev counter, speedo, fuel and temp gauge (I like mechanical things

There are more and more TFT displays used in outdoor applications, such as automobile display, digital signage and kiosks. High ambient light in outdoor environment often causes wash-out image and renders the screen not readable. Readability & sustainability of TFT  display under direct sunlight is becoming vital. Topway Display has been developing sunlight readable LCD display solution for years. The company understands the ins and outs of sunlight readable TFT LCD.

Visibility is the ease with which a viewer can detect an object, or in more scientific term: the relationship between luminance contrast and human eye’s threshold. Therefore, the higher an object’s contrast is, the better is its visibility.

For an LCD to be readable in outdoor environment with very bright ambient light, the LCD screen’s brightness needs to exceed the intensity of light that is reflected from the display surface. To be comfortably viewed by human eyes, the LCD’s brightness needs to exceed its reflected light by a factor of 2.5 at minimum. Naturally, to make an LCD sunlight readable, we can work on two areas, increasing brightness or reducing reflectance.

On a clear day in direct sunlight, the ambient brightness is about 6000 cd/m2. And a typical TFT LCD with touch screen reflects about 14% of ambient light, which is around 840 cd/m2. These days, most LCD displays use LED backlight as light source. It is not too difficult to increase an LCD’s brightness to 800 ~ 1000 Nits, to overpower the bright reflected sunlight. Thus, you have a sunlight readable TFT LCD.

However, this method requires more backlight LEDs and/or higher driving current. The drawbacks are high power consumption, more heat dissipation, increased product size and shorter LED backlight lifespan. Apparently, increasing backlight to make TFT LCD sunlight-readable is not a very good solution.

Transflective TFT LCD is a TFT LCD with both transmissive and reflective characteristics. A partially reflective mirror layer is added between LCD and backlight. This change turns part of the reflected ambient light into LCD’s light source, increasing the TFT display’s brightness. However, transflective TFT LCD is more expensive than transmissive one. At the same time, the partially reflective mirror layer will block some of the backlight, making it not ideal in indoor or low ambient light environment.

What causes light reflection? When light traveling in one transparent medium encounters a boundary with another transparent medium, a portion of the light bounces off the border. Through the simplest version of Fresnel’s equation, we can calculate the amount of reflected light.

The total reflectance on a TFT LCD with touch panel is the sum of reflected light on any interface where two materials meet. As an example, between polarizer and display glass, the difference in index of refractions for the two materials is very small, around 0.1. So the reflected light on this interface is only 0.1%. As Fresnel’s equation points out, we should focus reflection reduction on air interfaces. For air, its index of refraction is 1; for glass, it is 1.5. And that results in a reflectance of 4.5%. Therefore, the three air interfaces contribute majority of TFT LCD’s reflectance, at about 13%.

The quick and easiest thing we can do to reduce air-glass interface reflectance is to use an Anti-Reflection and Anti-Glare film or apply AR coating. An external film with AR properties not only reduces reflected light, but also brings other benefits.

For food industry application, shattered glass is a serious problem. An LCD screen with external film solves this issue nicely. As for automotive applications, in an accident, broken LCD with top AR film won’t produce sharp edge glass that could harms auto occupant. Nevertheless, a top film always reduces TFT LCD’s surface hardness. And it is susceptible to scratches. On the other hand, AR coating retains LCD’s hardness and touch performance. But it comes with a bigger price tag.

Another quick and easy way to tackle reflectance is to affix a linear polarizer on the top of TFT screen. When ambient light gets to the top polarizer, only half of the light passes through. Which results in reflection light cutting to half. This is a very low cost way to increase TFT LCD’s contrast, such that making it more sunlight readable.

Laminating a circular polarizer in TFT LCD will get rid of a lot of reflectance. That is because when ambient light passes through circular polarizer it gets circularly polarized. And when it is reflected, the polarization direction flips by 180 degrees. So when reflected light comes back to the circular polarizer, nothing goes through to viewer’s eyes.

This method is very effective for an LCD display with resistive touch panel. We know resistive touch LCD has two air gaps: air gap between two ITO layers and air gap between touch panel and LCD display. Reflectance caused by the two air gaps is very high. Applying circular polarizer blocks off most of the reflected light, and makes the LCD display sunlight readable.

The disadvantage of such solution is its cost. Since we need not only a circular polarizer, but also a retarder film on the top of LCD display, making sure light originates from within LCD is not blocked by external circular polarizer.

Add AR films on both interfaces of internal air gap. The add-ons can reduce this area’s reflection from 8.5% to 2%. And since the AR films are not outside facing, they are much cheaper than the one used outside. Keeping the air gap also retains the ease of service, in case either touch panel or LCD display needs to be repaired.

The most effective way is to eliminate air gap totally, by using optical bonding. In plain language, we fill air gap with special optical adhesive, to smooth out the area’s refraction index differences. Such that reflectance caused by internal air gap drops from 8.5% to 0.5%. Optical bonding is expensive but effective way to improve TFT LCD sunlight readability. It enhances durability and resistance to impact. Moreover, no air gap means no moisture condensation and fogging.

There are many ways to make TFT LCDsunlight readable. They all have their own pros and cons. With 20+ years" LCD design and manufacturing experience, Topway knows how to create the best sunlight readable TFT LCD for challenging environments. Leave us a message and let"s start the conversation of creating suitable sunlight readable TFT LCD for your project.

When your embedded device needs a display, that product becomes one of the most important parts of the device. I have helped build hundreds of embedded devices with screens in my career. I share expert tips and my insights for what to consider when choosing one.

An embedded display is a screen that connects to an embedded device. The screen provides information about how the device is working and allows users to interact with it.

Sometimes called embedded touch, these displays allow users to interact with the device by touching the screen"s surface. Smartphones, including the iPhone, were among the first products to use this technology. Retail displays increasingly use embedded touch screens.

The basic standard screens for embedded systems might include a liquid crystal display (LCD). Embedded systems use two types of LCD modules: character LCD and Graphic LCD. A character LCD only shows characters and is the simplest and cheapest LCD technology. A graphic LCD is more advanced and displays images.

Engineers who want to include a display with an embedded system can design and create a custom model. Or they can use a pre-built model—or "off-the-shelf" display—in their embedded systems.

Provides a custom look: You can design a display to fit the design of the embedded device. This option can be crucial if your device needs physical buttons along with the digital or touch screen buttons. A custom screen also means users have a more integrated and satisfying experience with the device.

Doesn’t include features you don"t want: A custom model won"t have unnecessary extras (casework and cameras) that an off-the-shelf display might not offer.

The display won"t go off the market: When you create a display, you can make arrangements with your manufacturer to continue making it while continually improving it. That partnership can last the life of your embedded device, which might be longer than that of some off-the-shelf displays.

Can be less expensive: Upfront costs to design a display can be high and cost-prohibitive if you"re not producing a large number of devices. But per-unit production costs substantially decrease when manufacturing a large number of devices.

Slow to market: Designing a display takes more time and can delay the point at which you can produce your embedded device for the market. You"ll need to create drivers for the display controller. You"ll also need to do the work to ensure the display can provide basic graphic functions like drawing lines and boxes. Then everything must be tested and debugged. The entire process might add five or six months or more to production time.

Mechanical design challenges: Developing the mechanical design of the bezel and glass for the embedded display can be challenging. This part takes significant work and precision to produce a product that looks and feels like the best off-the-shelf displays.

Can initially be more expensive: The work to design and build a custom display will make the display—and the embedded device—more expensive at the outset.

They"ve been proven to work well: Off-the-shelf display modules come with components, graphical interface functions, and other components that are already tested and work well.

Faster to market: Since off-the-shelf displays have been tested and improved and work well, you can usually get your embedded device finished and ready for the market faster.

Reduced cost: If you are producing a large number of your embedded device, per-unit costs for a custom display might become low enough for them to be more economical. In any other situation, your cost-per-unit is likely to be less expensive with an off-the-shelf display.Advantages of an Off-the-shelf Embedded Display:

"The lower the volume, the less likely it is that you"ll do a custom design—that you design yourself," says Burkhard Stubert, an independent software developer and consultant specializing the embedded systems."

Consumer perception of your product: An off-the-shelf display that looks different than or otherwise doesn"t fit well with your device can be a negative. Consumers can see your product as less finished or professional.

Display support: An off-the-shelf display may need support from its manufacturer to continue to perform well. The product may also undergo continual changes and development. Those changes, or lack of support, can cause problems when integrating the display into your embedded device.

Becoming obsolete: Many off-the-shelf displays will have a life of only a few years before consumers expect to replace them with new and better units. That can be a significant problem if you expect your embedded devices to last much longer than that.

Poor Consumer Perception:An off-the-shelf display that doesn"t seem to fit with the device will make consumers think less of the product and your company.

Obsolescence:Some off-the-shelf displays will have a life of only a few years; that could be a problem if you expect the life of your device will be longer.

You"ll want to consider several factors as you think about building or buying an embedded display. Those factors include safety, how the user will interact with the device, and the device"s working environment.

Some embedded devices may only need a basic display that the user doesn"t interact with at all—a display showing the level of battery power for the device, for example. Other embedded devices will have a screen that has more user interaction.

"When looking at how a user interacting with the display determines the sophistication of the model I"m choosing. How big does it need to be? What is the type of information it will display? It starts that use caseof analyzing how the user is interacting with the system," says Brent Horine, Ph.D., a senior embedded software developer with Hypergiant, which offersfor ModelOps.

Many displays operate within embedded systems that are critical for safety. Devices include medical equipment, automotive components, and parts in other critical infrastructure. All aspects of your system, including the display, will need to meet certain safety requirements. Be sure to consider safety in all aspects of choosing or building the display for these types of embedded devices.

You might choose to have users interact with the screen mainly through physical buttons rather than through a touch screen. Using buttons will be cheaper; touch screens are much more expensive than a simple display. However, physical buttons can wear down and stop working, and most users expect touch screens with devices these days.

"People are just used to touchscreens from their phones," Stubert says. “If users don"t have that, they become very impatient. They want to know why the product doesn"t work like their phone."

Touch screens also allow engineers to reprogram the display interactions later if they want to change or add features, explains Horine. "Whereas it"s hard to add a (physical) button to a system after it"s been deployed," he adds.

Some embedded devices may need more than one screen. You can learn more about howfor your device. You can also see a Qt demonstration of the future of embedded displays thatto provide an exceptional user experience.

Off-the-shelf or custom?Probably the most important early decision you"ll make is whether to build a custom display or buy an off-the-shelf model that will work with your device.

Horine says some devices may need a simple LCD that"s two inches by one inch. "I can find someone who manufactures that. Then it"s just a function of building and doing the interface that"s necessary to make it work," he shares.

A primary consideration, of course, will be cost. You"ll want to evaluate the cost of creating a custom display compared to buying one off-the-shelf. You"ll also want to look at longer-term costs that come with either option.

With certain devices and situations, such as vehicles and agricultural and construction machines, you"ll want to ensure your device"s display is not distracting, explains Stubert.

Some displays in those machines and vehicles may have rotary knobs or joysticks that allow users to control the device. "You have a second method of input, which is important because a touchscreen always means that you have to look where you touch. So, you are distracted, which is not good in vehicles," says Stubert.

Embedded systems within specific devices will experience environments that affect the display. Engineers will want to consider these environments. Might the device and the display get wet often? Will the device experience significant vibrations, like in many machines or vehicles?

For an embedded device within a vehicle with large, vibrating components, Stubert advises, "You need a display that you can screw in tight, or which clicks into place and it"s so tight that you can hardly get it out again."

Displays require resources from the microcontroller or microprocessor in the embedded system. They will need additional memory for example. The microcontroller will have limited memory but must have enough to run the display.

Many embedded devices have limited power they can consume. You need to ensure that the display can do its job while operating within those limits on power?

The working conditions of the embedded device might quickly wear out a display that isn"t durable. You"ll also want to consider how people will use the screen and how often they might be touching or using it in general. If users will touch the display often, it needs to be able to handle that interaction.

If you"re buying a display off-the-shelf, you"ll want to know how long the manufacturer expects it to last. You"ll also want to understand the technical support the manufacturer offers if there are operational problems.

Custom or off-the-shelf displays will have software within them. You"ll want to make sure you can access development tools and other resources to maintain that software.

For an off-the-shelf display, find out how long the manufacturer will be making this particular unit. If you plan to use the screen in a device that you expect to produce for six years or more, you’ll have issues if the display will only be available for three years.

Industry requirementsYou will want to consider whether the industry in which people will be using the embedded device has specific operating requirements. Will there be lighting conditions, such as darkness or bright sunlight, that might affect the screen?

Be sure to test how easy it is to read the display in various environments. Consider the contrast between the type of the screen and its background and the angle at which the users will view it, and if that affects their experience.

Qt"s Embedded Product Planning and Requirements Guide provides engineers with more details about the top embedded displays. The guide compares key features of the displays to help make your decision easier.

Displays are an important part of many embedded devices and can often be the most expensive element in your design. Choosing the right one is vital for the success of your device. Once you"ve selected a display, you"ll want to learn how to streamline the user interface design for the embedded device.

Qt Design Studiohelps you create beautiful user interfaces once you"ve chosen the right display for your embedded device. Qt Design Studio closes the gap between designers and developers allowing you to work simultaneously with one unifying framework, one common language, fewer feedback loops, and faster iterations.

I need to replace my cracked digitizer/glass on my OnePlus One and it seems changing only the digitizer is kinda hard so next thing is to get the full LCD to replace.

It seems logical that lcd + frame is easier but it seems it requires to move components/motherboard around which for me seems more prone to mistakes and problems then just buying an LCD and putting it into my old frame.

Transflective displays both transmit and reflect light (hence the name), eliminating the need for a backlight under sunlight or ambient light conditions and thus, saving energy. But like advanced technology vehicles and solid-state lighting, transflective displays entail a higher upfront cost for long-term savings.

As explained by Dave Hagan of Sharp, “A transflective display has both a transmissive and reflective mode of operation. Each pixel can generate color/brightness by controlling the amount of light transmitted from a backlight or by controlling the amount of light reflected from an external light source.”

“To have enough brightness in a backlight to overpower bright ambient light would require a specialized backlight with a tremendous amount of output power – and an equally tremendous power draw. The solution is a transflective display, because it can use reflected light to create a readable display,” he said.

“The transflective display remains readable in bright light without requiring a specialized backlight. This reduces thermal issues and power consumption,” says Hagan.

But the enduring popularity of incandescent lightbulbs and plasma TVs proves that consumers are willing to trade efficiency for aesthetics (and in some cases, functionality). What they aren’t willing to trade is aesthetics (and a higher upfront cost) for long-term energy savings. And that’s why transflective displays, like hybrid cars, are a tough sell.

The same goes for small electronics – the key is to seize the customer’s attention, like a carnie waving a fancy stick. And no consumer gadget waves a bigger stick than mobile phones. According to a CTIA report, telecoms have achieved 104.6% market penetration in the U.S. Nearly 1/3 of all households don’t even have a landline.

And this is where transflective displays come up short. For one, the cost for fitting color TFT displays with transflective technology is prohibitively expensive. OEMs would inevitably pass this cost on to consumers, and telecom patrons are notoriously finicky (and with good reason).

“Transflective technology is very easy and cost-effective for passive monochrome displays; it is not as easy or inexpensive for color TFT displays,” said Polshak.

And let’s face it – aesthetics do matter. Otherwise, we’d all be toting primitive brick phones and watching giant cathode-ray tubes. So it’s important to consider the point-of-sale issue.

Transflective displays are more efficient than their transmissive cousins, but the power savings is offset by a loss of contrast. If they’re not viewed under direct sunlight or bright ambient light, transflective displays have a tendency to look washed out.

According to Hagan, “If you compare a transflective display to a reflective display, without power applied, the transflective display will have a slight silver tint to it. The transmissive display will appear black. Except in very high ambient light conditions, the transmissive display will look better.”

OEMs know that consumers love their shiny gadgets (this editor has a particular affinity for his shiny iPhone), so companies like Apple are mindful of contrast ratios and brightness levels.

Says Ralph Polshak, “Since cell phones are by far the largest market for small-format color displays, they really drive the industry as a whole. So when cell phones stopped using transflective displays, manufacturers really stopped talking about and developing them.”

A combination of LED backlighting, anti-reflective surface treatment, and even memory LCDs and E-Ink (or other bi-stable technologies) could fit the bill.

In fact, the increased efficiency and reduced cost of new backlighting techniques is partially responsible for the ignominious retirement of transflective displays in the first place.

“As LED backlighting became more and more efficient it became easier to build very high bright displays to compete with direct sunlight. It is much easier and more cost effective to ‘high bright’ an existing transmissive TFT array backlight than re-tool the very expensive TFT array to add the inner reflective mirror that makes it transflective,” said Polshak.

Hagan concurs: “As LED backlights become more efficient, displays are becoming brighter for less power. These displays have the advantage of being brighter, higher contrast, and cheaper than the equivalent transflective display.”

E-Ink – owing to its efficient bi-stable properties – would be a fine replacement for transflective displays, but heat can adversely affect it. And memory LCD is monochrome
