The small tft lcd display can be drived byRaspberry pi, Arduino, STM32 via SPI interface, or MCU interface, we also have the HDMI small tft display, that it can be drived via HDMI port.

We have small tft display from 0.96" ~7" tft, the display resolutions have 80x160 pixels, 240x320 QVGA, 320X480 HVGA, 640X480 VGA, 800X480 WVGA, 1024x600 resolution, etc....

The 0.96" tft lcd is ideal small lcd display to replace the small oled display 0.96" monochrome, it is 256k colorful, as thinner as the oled screen, but higher resolution than 0.96" mono oled display, the small 0.96" tft lcd backlight is as lower power as OLED screen.This small lcd display only 0.96" in diagonal size, and with full color display, it is as thin as oled display, but with cost competitve than small color oled screen.

The 0.96" small lcd display could be used for wearable device,hand-held equipment, smart home control which requires smalllcd display in high quality and colorful image.such as smart bracelet for the sport and medical application. the 0.96" small lcd display could be used for smart home appliances as well, such as smart door lock, ketch devices, white goods, etc.,

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.

Custom built Tft lcd display, for example, is one of the most accurate sizes. Tft display for the- width, depth, and frame of the displayedftftalcd display, it can be customize into shapes, sizes, and displays. Different sized Tft displays offer different sizes.@@@@@

Larger Tft display, for example, is a for-the-shelf display. Often display larger thanft lcd displays, they may be more suitable. Custom-size Tft display for purposes, such as a display- the function is the same for larger Tft lcd, and they are more suitable for displays. Customer tft display such as a full-sized Tft display may be better for smaller displays, such as a 14-pixel Tft display, 4 larger Tft lcd displays, and 4 larger Tft lcd displays are the options.@@@@@

Customizable Tft display, lcdds offer customization as well. Unlike conventional displays, the custom size Tft display is only one of the key sizes that users can consider. Findors of different sizes are availableftft lcdds, one are the for sizes.@@@@@

We will organize the kinds of display interfaces we offer, and how they differ. You will get to know what kind of external and internal interfaces we have and what are their main applications.

First, let us start with dividing internal and external interfaces in LCD modules. Internal interface of display means it used inside the device. Those are usually the embedded interfaces that are not visible, and we do not have access to them as the users of the device. External interfaces, on the other hand, are connected to the device using a cable. Once we have defined internal and external interfaces, both of these categories come as universal or image transfer interfaces.

Let’s try to get the interfaces right. For internal interfaces, interfaces embedded into the device, we have universal interfaces and image transfer interfaces. Universal display interface can send other data, not only an image. Being universal, they are not perfect for image transfer, because in most of the displays used nowadays, the image transfer is one of the most demanding. The bit rate, the data transfer needed for the image transfer is rather high. Higher that many universal interfaces can offer. If we need to send an image every once in a while, then we don’t need very high bandwidth. If we do not need live video stream, then we can use some of the internal universal interfaces such as SPI, I2C or even slow interfaces as RS232 or UART.

It can be fast but is not fast enough for live video. The baud rate can be 1 MBd, but it can also be 10 MBd or even 50 MBd on the SPI or QSPI. QSPI is a Quad SPI, a kind of modification of SPI that is faster. But still this interface is very universal, we can use it to connect memory or some input and outputs internally in our device. In the display universe the SPI is used for simple displays, for small size displays, where we can transfer the image relatively fast, because the resolution is low. The maximum size for SPI display interface would be 3.5 inch, 320 by 240 pixel TFT displays. If we have higher resolution, image transfer will be too slow to use SPI even with a high-speed SPI.

If, for example, the Master is sending some data, the only thing Slaves can do is to receive it. And then we need to wait a little bit for the Master to finish. We can then respond as Slave to Master. In I2C Slave selection works a little bit different than in SPI, where  we had a Chip Select line (CS line) or SS line to select from. In I2C we first need to send the logical address to the interface that is being written by Slaves. In general, this procedure is slow and universal interface used also to connect the simple memory and some other I2S that we have around our microcontroller on the PCB. It is very useful, but usually not used for image transfer. This interface is very popular in the display world for touchscreens. Most of the embedded touch screens that we use have I2C interface because the touchscreen does not generate many data. We only have coordinates of the finger or few fingers at most, that need to be sent back to the microcontroller, to the device processor. The slow baud rate is good enough for the touchscreen, but not enough for the image.

That is not a case for SPI or I2C, because we have a clock there that gives the speed to every device. Then each device works according to the clock. In UART we do not have a clock. It is rather not used for image transfer. The UART, or SPI, or I2C can be used for low resolution displays. For high resolution displays we need an Intelligent Display, a display that will generate the image internally and through these slow universal interfaces we only send commands, or we send the image once, the image is being stored into the internal memory of the intelligent display, that we will use later sending the commands. You can find Riverdi’s intelligent display line on our website: https://riverdi.com/product-category/intelligent-displays/.

These Riverdi products are very advanced Intelligent Displays, made with Bridgetek controllers. The controllers use SPI and QSPI for communication. That means your software, your system, your microcontroller can be simple. You can use SPI interface to drive them, and you can still have high resolution image, even as high as 1280 by 800 pixels in 10.1-inch LCD displays. So, please remember that if you want to use a slow universal interface and have a high-resolution image, you need to use an Intelligent Display.

There are also the internal image transfer interfaces. The image transfer interface allows continuous high speed image transfer. Internal transfer is high enough to refresh the display many times per second. This is called the refresh rate of a display. When you go to a display, monitor, or TV set specification, you will see  refresh rate or maximum refresh rate parameter. If it’s 60 Hertz, that means the display image is refreshed 60 times per second. More advanced displays would have higher values, like 100 Hertz. The refresh rate means we need to send full image 60 times or 100 times in each second. To visualize this amount of data, we need to multiply refresh rate by the resolution of the screen. For example, for a 7-inch Riverdi LVDS display with resolution 1024 by 600 it is roughly 600 thousand pixels.

The most common internal image transfer interface in industrial LCD displays nowadays is LVDS – Low Voltage Differential Signal. A crucial feature of this interface is that it is differential. It means that the signal is immune to interference and we can use a twisted pair of wires to transfer the data. We can send data fast and it will not be corrupt by any noise, interference. This kind of data corruption is quite common in other interfaces.

The next, older image transfer interface is called RGB. Name comes from the colors sent parallelly to the display: red, green and blue. LVDS is a serial interface and the RGB is a parallel interface. The main difference is that RGB is not differential, so it is easier to disturb signal with noise and you configure the speed of this interface too high. Parallel interface means that we send every bit in a separate line. In theory this interface could be fast, but because it is not differential, the transfer speed is limited. Moreover, the RGB display interface will work with rather small screen sizes –  usually up to 7-inch or 10-inch.

12 inch screen size is the total maximum for a LCD display with RGB interface, but the resolution will be lower, like 800 by 600. For this display size it is very low resolution. This is the reason why the 7-inch is size above which the LCD displays are being switched from RGB to LVDS interface. Among Riverdi products (if you go to the Riverdi website and to the IPS display tab), there are displays without the controller, and the small displays like 3.5-inch, 4.3-inch and 5-inch are equipped with RGB interface. But when you go to the 7-inch LCD displays tab on Riverdi website, you will find RGB, LVDS and MIPI displays. But when you go to the 10-inch or bigger displays, you will only find the LVDS displays because our 10-inch LCD displays are high resolution 1280 by 800, and it is impossible to build it with the RGB interface.

MIPI – Mobile Industry Processor Interface – is an internally embedded image transfer interface, getting popular these days. This kind of interface is used in mobile applications, tablets or mobile phones, but it is entering as an option in industrial applications. In Riverdi we offer 7-inch MIPI displays, but please be careful with other MIPI displays on the market. Many come from mobile phones or tablet market. Also, the TFT glass availability may not be stable as the mobile market changes really fast, every six months or every year. When you buy a 7-inch Riverdi MIPI interface display you are safe, because it is an industrial display.

This is why we have a limited number of displays with MIPI interface – we want to be sure that what we sale will be available for a long time. Longevity is one of Riverdi’s core values and we do not want to deliver anything that will not be supported for a minimum 3 to 5 years. It is because many of our customers are making industrial, medical or military devices and they need displays to be available long-term.

Key takeaway: Vx1 is a super-fast interface used for high bandwidth image transfer, with high refresh rate and high-resolution displays, used in 4K screens and above.

The last internal image transfer interface is Embedded DisplayPort (eDP). We call it the new LVDS, because many new industrial displays are equipped with the eDP. If you go through industrial manufacturers of TFT LCD displays, you will notice increasing number of models available with the eDP. eDP is also a native interface in new Intel or AMD based processors.

Key Takeaway: With the embedded DisplayPort as a native display interface you can cut down costs, because you do not need anything extra to connect a display to the processor.

Now, with the processors on the market, we need displays with embedded DisplayPort. Many laptops or monitors already use embedded DisplayPort as an internal interface instead of LVDS. LVDS still is the most popular industrial LCD display interface. All the internal image transfer interfaces like MIPI, Vx1 and eDP are variations of LVDS, where the protocols and the signals are a little bit different. For example, for eDP we can have lower noise and reduced power consumption. All of them have advantages over regular LVDS, but they are all LVDS type.

Now, let’s take a closer look at external interfaces. Those are the ones that we usually have direct access to. It can be TV or monitor connected to your computer with the HDMI . It can be a DVI usually used for monitors. Or VGA which is an outdated image interface for monitors.  The DisplayPort that is a HDMI successor. Finally, an universal USB-C, the most common interface nowadays used to connect devices.

The last external interface that we can find in our devices nowadays is a DisplayPort. DisplayPort is similar to HDMI or DVI. It can also transfer image and sound. It is even faster than the HDMI. Usually, the DisplayPort is used for high resolution displays, for new monitors and TVs with 4K or 8K resolution where it is really hard, or nearly impossible, to achieve such resolution using HDMI interface.

I may have found something that makes it a little closer to that true plug n’play goal – the 3.5″ TFT screen from NeoSec Solutions. They offer a similar product to the PiTFT however overall I’ve found it a lot easier to set up.

It’s hard to look at any small touch screen for the Pi without comparing it to the ever popular PiTFT – so rather than pretend to not be comparing it – this review will face the boards off against each other and see what’s the best screen in each category. I don’t normally do this, but it just makes sense in this scenario.

The NeoSec 3.5″ TFT is a small touchscreen LCD display that pushes on to your Raspberry Pi (Model A/B) via the GPIO pins. The screen makes use of nearly all available space above the Pi, allowing a decent 480×320 resolution. It comes packaged in a small clip-top box with everything inside.

The image file is the big winner here for me. I put the image on to a blank SD card (8Gb as it didn’t fit my 4Gb), turned on the Pi, and it was ready to go. No messing around, no code – just a working screen out of the box. Compare that to the hassle of some other TFT screens for the Pi and you’ll see why I’m so impressed with this.

The screen itself is nice and bright, with rich blacks, and that 480×320 resolution keeping the font to a nice size to see as much as possible on screen. I love the size of this screen, and the way it covers the Pi completely. There’s also very little blank space on the screen itself.

Whilst I dont normally compare products when writing a review, theres an obvious competitor that you cant help but compare to when you see other small Raspberry Pi screens…so this review will focus on the pros/cons of the NeoSec 3.5″ TFT compared to the 2.8″ PiTFT from Adafruit.

Although these screens are different in features and size, they’re suitable for comparison in terms of “Pi sized touchscreen vs Pi sized touchscreen”.

The PiTFT requires assembly, including GPIO and button soldering, and taping the screen to the PCB. That tape isn’t very sticky at all so you’ll probably need to get your own – I used No Nails tape.

Verdict: I think self-assembly can be a good learning experience, but considering how many people I’ve heard complaining of the difficulty of assembling the PiTFT, NeoSec wins this one.

The NeoSec weighs in at a more comfortable 3.5″ and a clearer 480×320 resolution. The 3.5″ screen covers more of the Pi, which I think looks much smarter. That extra screen space does come at a price, which is the slightly more delicate feel it has, and no mounting holes for support screws like the PiTFT:

The font on the NeoSec screen seems smaller yet clearer, allowing more on screen, but there may be a way to match this on the PiTFT that I haven’t discovered yet:

Verdict: You can’t argue with the bigger screen of the NeoSec, and it does seem to have much better colour and clarity. It seems an easy decision when considering these two as being in the same product market – however the PiTFT certainly feels more sturdy with that PCB surround. I’m going for the NeoSec here – but it is tight.

The PiTFT has holes around it to use nylon screws as a screen support. It also has PCB area around the screen acting as a bit of protection. The PCB covers the entire underside of the screen, ensuring no light comes out of the back.

Verdict: The PiTFT wins this one, it feels much more secure, and I’m pretty sure light bleed from the back isn’t meant to happen – even if it does look cool.

The PiTFT has an optional upside-down connector to attach a belt to breakout to a breadboard. I don’t like the whole belt thing, it feels a bit too 90’s computing for me, and the upside down back to front thing makes it hard to do something different like add a regular GPIO header.

Verdict: Tie – it all depends on what you want the screen for. The PiTFT may be better for breakout projects, whilst breaking off the GPIO tab on the NeoSec may be better for those looking for a simple screen solution.

The PiTFT comes ready to fit 4 tactile buttons to, however these need to be purchased and fitted separately. The blue PCB of the Adafruit board is attractive when compared to traditional colours.

The NeoSec on the other hand, was much easier to get going. I simply installed the image provided on the DVD supplied (no long download required) and it worked straight away. You have to tweak a couple of settings if you’re using a Rev1 board, but with a Model A/B it’s real easy. You also don’t seem to need to push things to the display using code – it picks up everything as default from what I’ve tested.

I thought I’d add a final section on support, as I had a few questions while writing this review, and previously had questions on the PiTFT when I first used it.

The PiTFT benefits from the massive following and fan base that Adafruit command. Their forums are full of information, and generally a lot of people buy their products, so most people have had the issue and written about it on blogs and forums.

It’s important to stress “personal choice” here. Everyone will have different uses for a Pi-sized screen, so a lot of us will probably sway one way or another purely based on the features and functionality we need.

Sure the PiTFT has that sexy blue AdaFruit styling we all love, and the screen feels more secure and has an overall better ‘feel’ to it (plus those optional buttons are very cool), but the setup involved many hours of my life that I’m unlikely to get a refund for.

The other reason is purely the size of the screen – the 3.5″ full-size unit looks so much smarter than a 2.8″ surrounded by PCB – and it’s simply ‘more screen’ – that’s why we bought it in the first place right?

The extra size and resolution gives a much better picture too – the colour and clarity are beautiful. Add to that the extras such as the pen and the touchpad, and for a extra few dollars the NeoSec feels like the better buy.
