tft display failure price
Whilst riding recently my TFT screen just went of, completely blank/black. The screen height adjuster worked (it was set on this option) so I figured it was nothing too serious. I"d not jolted it or gone over a pot hole or anything. After 15 to 20 minutes it came back on. When I got home I stopped and turned everything off, and re started the bike. as I did, the screen just showed a series of grey/black lines, then went creamy colour and slowly came back to normal. I"ve shown it to my local dealer, and have a couple of videos of the issue. They have put a warranty claim in to Triumph UK. lets see what happens.
The TFT glass cell makers such as Tianma,Hanstar,BOE,CPT,Innolux has reduced or stopped the production of small and medium-sized tft glass cell for months due to the low profit and focus on the size of LCD TV,Tablet PC and Smart Phone .It results the glass cell price in the market is extremely high. We deeply regret that rapidly rising costs for tft glass cell necessitate our raising the price of tft display module.We have made every attempt to avoid the increase, we could accept no profit from the beginning,but the price is going up frequently ,we"re now losing a lot of money. We have no choice if we want to survive.
The screen on my FT9000D has failed. It"s either blank or displays colored vertical lines. I did speak with Tim Factor at Yaesu just before the national lockdown and sent him a picture of the screen, but haven"t heard anything since. I assume the service dept. is closed. I"d like to know if anyone else has experienced the same problem and found a solution (short of shipping the radio back to Yaesu) .
If it were an Icom 7800, resolving the problem would include reseating the ribbon cables attached to the front panel and retesting the display. This might be the way to go with your 9000 too.

I had an issue twice losing the display. It was caused by up plugging the radio power cord . The previous owner told me always keep the power cord plugged in with power on if plugged into a power strip. I’ve done that and never had an issue again. It’s been a year since. Hope you resolve your issue.

John, to be clear: Do you mean that simply replugging in the 9000 and leaving it on (rear power switch) cured your display problem, with no other action? Unplugging the set will cause the oven to lose power and the reference oscillator to be off frequency initially when later turned on.

Ron, the previous owner told me not to take power off from the rear switch. This could cause things to happen to the display. I just use the power switch in front of the radio to turn the power off. I haven’t had an incident in over a year now.

If you accidentally lose AC. Like Unplugging the wrong plug, power strip switch or utility failure. Turn off the Rear switch. Then apply power to the cord. Turn on the rear switch. (Or external supply. )

That"s right Andy. I"m 99% certain that the external monitor had no display when the TFT failed. I"ll plug it in and recheck it over the next few days to be sure. If it was working I could use the radio.

If there is no display on the monitor then the DMU computer is likely the failure. The DMU PC module has an interface between it and the radio’s TFT. But the PC module has a direct VGA output. That is what is connected to the monitor port.

I just connected an external monitor to my 9000. No display. I did speak to Tim Factor this afternoon; the consensus is that the DMU has failed. With shipping, parts and labor, it"s about a $2000 repair. Tim told me that too much instrumentation is needed for me to install a new DMU myself. Looks like I"ll be buying a new radio !

With the continual development of LCD technologies, TFTs have become widely available at a lower price point. The manufacturing process of TFTs has been standardized which has changed the industry for display applications, making TFTs a feasible replacement option for graphic LCDs. This application note will discuss the options for replacing a graphic LCD with a TFT LCD. Considerations of price, size, features and functions will be analyzed to evaluate the options for TFT displays in place of a graphic LCD.
The two displays that will be reviewed in this application are described in the table below. These displays are similar in size and cost but vary in features and technical specifications.
Graphic LCDs are common for industrial applications where the features of TFTs are not justified by price. In recent years, TFT manufacturing has broadened its standard manufacturing process, making TFTs a competitor in typical graphic LCD applications.
TFTs offer additional features that graphic LCDs cannot provide. Such features consist of high color and resolution. TFTs also have the benefit of integrating capacitive and resistive touch functions to the display. If you are considering replacing a current graphic LCD, it may be time to switch to a TFT.
Graphic LCDs are a common display for industrial applications where vivid and high-resolution graphics are not essential to the application. Graphic displays typically have an 8-bit parallel interface which does not require a high frequency clock to communicate with the display. The graphic display in this example has 128 x 64 dots of resolution. This means the memory requirement of the frame buffer for this display is small and is provided by the IC on the display. Graphic LCDs do not offer RGB pixel color and display pixels as either on or off.
Significant limiting factors for graphic LCDs include the resolution and color depth of the display. The options for what can be displayed is restricted to a small area, in this example 128x64 pixels. This means that the image must be very low resolution and text must be very small. Typical graphic LCD applications display text or small user interface option.
The dimensions of G12864B-BW-LW63 are reviewed below. This graphic LCD is close in size to E30RA-FW400-N, the main differences being the mounting of the backlight and the depth of the displays. This graphic LCD is transmissive, STN blue, with a white LED backlight. The demo images will be displayed with white pixels and a blue background.
An example application for this graphic LCD will be reviewed in comparison with the TFT. The graphic LCD is interfaced over an 8-bit parallel connection. The display controller IC, ST7565, provides 8 pages of display RAM, an internal oscillator, and power regulation functions. This makes it easy to control a graphic LCD with a simple 8-bit controller because the main functions are provided internally.
The graphic LCD will display a menu followed by a temperature measurement screen. This is to provide an example of a typical graphic LCD application. Below is an example of the menu and the temperature measurement screen before they are uploaded onto the display.
Pixel size is limited for graphic LCDs. The full page consists of 128x64 pixels so the images must be low resolution and small. The amount of RAM provided by the embedded IC of the display will support 8 full pages of display data. The images must be black and white but will appear as white and blue once uploaded to the display. Below are the images of the display with these example applications uploaded.
The individual pixels can be seen on the graphic LCD and can be altered to project a monochrome image. STN blue graphic LCDs will display white pixels over a blue background. The amount that can be displayed in one page is restricted to 128x64 pixels. Simple icons and characters are common options for graphic display applications.
The design for graphic displays must be simplified to low resolution texts and icons. When you get down to a low resolution, such as 128x64 pixels, every pixel counts in creating a coherent image. This is why there is a standard set of icons used, and you will see them across graphic display applications. These icons are reminiscent of an early Windows computer era, 1980’s/1990’s. Most of these applications have already transferred to higher resolution and colored TFTs.
TFTs have begun to replace graphic LCDs in many applications. This is largely due to the price decrease of the displays and the electronics required to support them. The price of microprocessors and memory chips has substantially decreased, making TFTs a competitive alternative to graphic LCDs. TFT displays have the benefit of higher graphics quality, color, and speed for no extra cost.
The TFT used in this application is close in size to the graphic display. The display can be used both vertically and horizontally by changing the scan direction register. This can also be done by changing the page and column addresses before writing to RAM. The dimensions of the TFT are reviewed below from a vertical reference.
TFT displays offer a higher resolution and color depth. The TFT in this application has a resolution of 480x854 and can display up to 16.7 million colors. The combinations of color and the number of available pixels drastically increases the options for what can be displayed.
The TFT’s size is similar to the graphic LCD, but the resolution area is over six times larger. This makes a significant difference in image quality and available area. Below are the two graphic LCD demos displayed on the TFT.
Both graphic LCD demos can fit in the TFT display resolution and only take up a fraction of the total area available. The resolution of the TFT is highlighted by the amount of data that can be stored in one frame of the display area. Each pixel makes up only a small part of the image which means high resolution images can be portrayed. The same image is uploaded on both the graphic LCD and the TFT below.
TFTs also differ from graphic LCDs because they can display colors. This display supports 24-bits of color data for each pixel. This mean there are 16.7 million colors to select from. The graphic LCD writes to each pixel as on or off. The TFT assigns each pixel 24-bits of color data which means there are 16.7M unique colors that can be displayed.
TFTs have become increasingly standard for most display applications. Even if the application does not require high definition for its intended function, the comparable price for each display type makes the graphics quality an added bonus.
E30RA-FW400-N uses a 24-bit parallel interface and renders 24-bpp of color data for each pixel. This interface is fast enough to support this resolution and color depth to maintain a frame rate of 60 Hz. The only draw-back to this interface is the number of data pins that must be connected to a controller. TFTs come with many different interfaces depending on the resolution.
The graphic LCD demo can be recreated for the TFT to display more complex elements and colors. The addition of color and an increased pixel area gives the display more flexibility on what can be displayed and the quality of the image. TFT displays also have the benefit of touch interface options which can incorporate the user interface on the screen. Below is the example displayed on the TFT.
Some considerations should be made when switching from a graphic LCD to a TFT. A higher resolution means more pixels per frame. An increase in color depth means there is more data assigned to each of the pixels. The memory cost for one page of data can add up quickly depending on size and color depth chosen. The TFT in this example needs a minimum of 1.23MB if using the 24-bpp color depth. A lower color depth can be chosen through commands if you want to reduce memory costs.
The display also requires a higher speed interface to support its resolution and color depth. This display can be interfaced over a 16, 18 or 24-bit parallel interface with a clock cycle of 24.5MHz. This is the minimum speed required to maintain a frame rate of 60Hz. A high-speed controller is also required for this. Since high-speed controllers are becoming more affordable, these constraints are not as significant of a factor as they used to be.
TFT stands for thin-film transistor, which means that each pixel in the device has a thin-film transistor attached to it. Transistors are activated by electrical currents that make contact with the pixels to produce impeccable image quality on the screen. Here are some important features of TFT displays.Excellent Colour Display.Top notch colour contrast, clarity, and brightness settings that can be adjusted to accommodate specific application requirements.Extended Half-Life.TFT displays boast a much higher half-life than their LED counterparts and they also come in a variety of size configurations that can impact the device’s half-life depending on usage and other factors.TFT displays can have either resistive or capacitive touch panels.Resistive is usually the standard because it comes at a lower price point, but you can also opt for capacitive which is compatible with most modern smartphones and other devices.TFT displays offer exceptional aspect ratio control.Aspect ratio control contributes to better image clarity and quality by mapping out the number of pixels that are in the source image compared to the resolution pixels on the screen.Monitor ghosting doesn’t occur on TFT displays.This is when a moving image or object has blurry pixels following it across the screen, resembling a ghost.
TFT displays are incredibly versatile.The offer a number of different interface options that are compatible with various devices and accommodate the technical capabilities of all users.
There are two main types of TFT LCD displays:· Twisted nematic TFT LCDs are an older model. They have limited colour options and use 6 bits per each blue, red, and green channel.
In-plane switching TFT LCDs are a newer model. Originally introduced in the 1990s by Hitachi, in-plane switching TFT LCDs consist of moving liquid pixels that move in contrast or opposite the plane of the display, rather than alongside it.
The type of TFT LCD monitor or industrial display you choose to purchase will depend on the specifications of your application or project. Here are a few important factors to consider when selecting an appropriate TFT LCD display technology:Life expectancy/battery life.Depending on the length of ongoing use and the duration of your project, you’re going to want to choose a device that can last a long time while maintaining quality usage.
Image clarity.Some TFT displays feature infrared touchscreens, while others are layered. The former is preferable, especially in poor lighting conditions or for outdoor and industrial applications, because there’s no overlay and therefore no obstructions to light emittance.
The environmental conditions make a difference in operation and image clarity. When choosing a TFT for outdoor or industrial applications, be sure to choose one that can withstand various environmental elements like dust, wind, moisture, dirt, and even sunlight.

When it comes to choosing what to use for your displays, going with the standard can get you farther ahead than thinking outside the box. TFT LCD display gives you an edge for your advertising needs, television screens, or even phone screens.
A thin-film transistor (TFT) is one of the technologies commonly used for building LCDs. With this technology, your LCD is guaranteed a sharp, clear, and full-color display and high-quality performance.
When a signal sent to a pixel also affects the pixels next to it, crosstalk This runs the risk of distorting the quality of your image. With TFT, crosstalk is significantly reduced with the TFT layer integrated into the screen itself. With every pixel corresponding to the signals meant only for them, you are guaranteed the best resolution and image quality.
In the LCD industry, the most popular kinds of displays are manufactured and innovated the most. Unlike other types of LCD technologies, the TFT module is available in different sizes, ranging from cellphone sizes to larger TV sizes, to suit your needs.
All LCD displays have a determined number of hours of use before they become half as bright than when they were turned on for the first time. This is called half-life. Although research is still ongoing regarding half-life, TFT displays are said to have more than 14,000 hours of half-life.
Compared to CRTs, TFT LCD modules have lower heat release. Moreover, they emit lower electromagnetic emissions which significantly decrease visual fatigue. This means that TFTs are ideal for devices and displays that require an audience’s prolonged attention, such as cell phones and television screens.
While the TFT’s power consumption is significantly lower than OLEDs in white displays, there are also emerging TFT displays in the market that integrate smart technologies that can save up to 50% energy on battery-operated devices.
One of the notable disadvantages of TFTs, however, is its cost. The characteristics detailed in the previous section, however, must be considered worthy of investment. Moreover, as the number of TFTs floods the LCD display market, the price for TFTs are decreasing by the day.

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.
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. Click to view: what is TFT LCD, 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%.
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.
