wsvga tft lcd white screen factory

The game will compile and work, I can see it working on the serial monitor.  The issue is the screen stay white.  I can load examples codes and the display screen works perfectly.

No changes made, powered up on the third day, and nothing but a white screen on the ILI9341? So i say, must have blew the t4 some how. Hot air removed the t4, on goes the new one and again a few runs later and i get a white screen again? Checked all my pin assignments, voltages and they are all good.

I picked up the project again today and de-soldered my SAMD51 T4 clone pcb as I need speed! The T4 would have been perfect, so tried a few code changes, got the screen running in the setup function (static text etc), but as soon as it enters the loop(), you guessed it....white screen. Its as if the t4 is too fast on spi or something, but I have changed the clock speeds down to 5mhz and yield the same results...

TFT stands for ‘Thin Film Transistor’ – it is a type of LCD that gives higher resolution and better image quality than standard LCDs. These are usually coloured, but Mono is becoming more popular and therefore more readily available.

Displays are measured using ‘lumens’, which are also known as ‘nits’. The brightness should be measured in 5 different points on the front of the display to give you an average reading. Adding filters, touch screens or lenses will all decrease the overall brightness of a display so it should always be measured after these add-ons. Some displays are now as bright as 1500 nits or lumens.

This depends on the application and what you want to achieve, this is a very subjective question. LCDs can be very cheap – the older green and black ones (think calculators for example) can be extremely cheap, but they are not as colourful or easy to read as newer technologies. TFTs will give you full colour and a higher solution than an LCD, but they are more difficult to drive and tend to be more expensive. OLED is a relatively new technology. OLEDs are lower power than TFT and offer very good viewing, but have lifetime issues and are only available in smaller sizes.

Capacitive touch is most commonly used in products such as smartphones. It’s used in all sorts of applications currently but it’s difficult to get working. Capacitive is a lot more expensive than resistive but it does enable nice gesture features and has the ability to have a cover lens. Resistive touch screens are much cheaper and easier to drive, but do suffer from a mottled effect over the display and can be damaged easily as there is no cover lens.

For LCD and TFT displays, most power is consumed by the backlight. If you turn the backlight off on a standard LCD, the display itself can run from batteries for many days.

Nearly all TFTs need to have their backlight on to be able to work, which is why your tablet or phone shuts down the backlight quickly when it detects you are not using it. There are some TFTs that can work with no backlight, but they are unique and expensive.

An LCD will work very well in direct sunlight. We actually use the sunlight as the backlight, as it bounces off the rear and becomes part of the display.

We can also achieve this in TFT by adding special films - it does decrease the overall brightness of the display but enables it to be run in direct sunlight.

We all use and handle TFTs in our daily lives with phones, monitors, laptops etc. All of these use TFT displays, but they are very different to TFTs we may use in industrial applications. Why is this?

Consumer electronics have a different specification requirement to those of us in the industrial world. From the outside, they may well look the same with the same TFT cell and white LED backlights, but the differences then start to show. Laptop screens for example are designed to be as thin and lightweight as possible – often just 3mm thick and very susceptible to physical damage, not something you would want in an industrial application.

Consumer TFTs are also designed for typically one product, and when the next one is launched their specification will change to meet the requirements of that next generation, often meaning things like mounting holes and connector positions have changed in the space of a few months.

Industrial displays have been designed and developed to overcome all of these issues. They use fixed rigid mounting holes, the interfaces are industry standard and most importantly they have a guaranteed lifetime of at least 5 years, so you can guarantee you will not have to redesign your own product due to TFT changes.

Intelligent Display Solutions (IDS) has recently introduced a whole family of industrial TFTs into RS Components, all incorporating the latest technology and all available for 5 years minimum.

Integrated cap touch screens and controllers, mean integration into your software platform is seamless with easy recognition for Windows, Linux and embedded platforms.

If you want to buy a new monitor, you might wonder what kind of display technologies I should choose. In today’s market, there are two main types of computer monitors: TFT LCD monitors & IPS monitors.

The word TFT means Thin Film Transistor. It is the technology that is used in LCD displays.  We have additional resources if you would like to learn more about what is a TFT Display. This type of LCDs is also categorically referred to as an active-matrix LCD.

These LCDs can hold back some pixels while using other pixels so the LCD screen will be using a very minimum amount of energy to function (to modify the liquid crystal molecules between two electrodes). TFT LCDs have capacitors and transistors. These two elements play a key part in ensuring that the TFT display monitor functions by using a very small amount of energy while still generating vibrant, consistent images.

Industry nomenclature: TFT LCD panels or TFT screens can also be referred to as TN (Twisted Nematic) Type TFT displays or TN panels, or TN screen technology.

IPS (in-plane-switching) technology is like an improvement on the traditional TFT LCD display module in the sense that it has the same basic structure, but has more enhanced features and more widespread usability.

These LCD screens offer vibrant color, high contrast, and clear images at wide viewing angles. At a premium price. This technology is often used in high definition screens such as in gaming or entertainment.

Both TFT display and IPS display are active-matrix displays, neither can’t emit light on their own like OLED displays and have to be used with a back-light of white bright light to generate the picture. Newer panels utilize LED backlight (light-emitting diodes) to generate their light hence utilizing less power and requiring less depth by design. Neither TFT display nor IPS display can produce color, there is a layer of RGB (red, green, blue) color filter in each LCD pixels to produce the color consumers see. If you use a magnifier to inspect your monitor, you will see RGB color in each pixel. With an on/off switch and different level of brightness RGB, we can get many colors.

Wider viewing angles are not always welcome or needed. Image you work on the airplane. The person sitting next to you always looking at your screen, it can be very uncomfortable. There are more expensive technologies to narrow the viewing angle on purpose to protect the privacy.

Winner. IPS TFT screens have around 0.3 milliseconds response time while TN TFT screens responds around 10 milliseconds which makes the latter unsuitable for gaming

Winner. 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.

Winner. While the TFT LCD has around 15% more power consumption vs IPS LCD, IPS has a lower transmittance which forces IPS displays to consume more power via backlights. TFT LCD helps battery life.

Normally, high-end products, such as Apple Mac computer monitors and Samsung mobile phones, generally use IPS panels. Some high-end TV and mobile phones even use AMOLED (Active Matrix Organic Light Emitting Diodes) displays. This cutting edge technology provides even better color reproduction, clear image quality, better color gamut, less power consumption when compared to LCD technology.

What you need to choose is AMOLED for your TV and mobile phones instead of PMOLED. If you have budget leftover, you can also add touch screen functionality as most of the touch nowadays uses PCAP (Projective Capacitive) touch panel.

This kind of touch technology was first introduced by Steve Jobs in the first-generation iPhone. Of course, a TFT LCD display can always meet the basic needs at the most efficient price. An IPS display can make your monitor standing out.
