tft display flickering raspberry pi for sale

I"ve been looking around for a small HDMI LCD screen to use as a seconday screen with Windows and it took a few months of research on and off before deciding on the Elecrow 5" HDMI monitor. For the most part, it took me a while because a lot of reviews here and on other sites were primarily about use and config with Raspberry Pi.

Thanks to reviewer Alan who gave a good review with plenty of photos that convinced me to go for it. Not sure if it"s just how Amazon stores user review videos but the video review was a bit pixelated so it was hard to appreciate the clarity of the screen but it seemed to be what I was looking for.

Having used it for a few months now I still can"t believe how clear and sharp the screen is! There are sadly no controls for brightness, colour, saturation or contrast but everything displayed looks very nice and accurate.

Usually when you see the resolution 800x480 you think how bad that looks when your PC doesn"t have the right drivers installed and it looks blocky. I know it"s all relative and about DPI but once I had it all connected and tested it was sharp and clear, almost HD. I wish I had bought one sooner as it is exactly what I was looking for having tried a Lilliput monitor.

As I"m using this with Windows, I"ve not needed to look through the included driver utility disc and not tried the resistive touchscreen so I can"t comment on those. Windows just detects it as a second display and lets me extend my desktop. No drivers needed. The box contains the LCD screen, a HDMI bridge connector that neatly connects the HDMI socket on the top of the screen to the HDMI socket on the Raspberry Pi when mounted together. Standoffs for mounting are also supplied plus a plastic stylus.

+ I was hoping for an on/off switch but no it only has a backlight switch which I wasn"t sure about to begin with but I"ve since found it very useful and better. I was thinking about buying a micro USB cable designed for Raspberry Pi with an inline power switch built in but for now the brightness switch is fine. As a blessing in disguise, it prevents Windows/DirectShow from blinking all screens when it realises a monitor has been disconnected, that blink would often cause the video on my TV app to freeze. Turning off backlight doesn"t cause DirectShow to have a fit.

+ Small and light enough that I have it attached to a gooseneck arm so can position it how I need. I was going to buy one of those mobile phone gooseneck arms but I kept reading reviews of some not even being able to cope with weight of a smartphone without drooping so I"ve used a photographic gooseneck clamp which is a bit overkill but no droop!

! Just one more thing Columbo! I had originally wanted to buy Revision B of this screen with capacitive touch screen because it has OSD menu buttons. I can"t find any manuals but I"m hoping that OSD buttons allows settings for brightness as that was my other preferred criteria. Having said that, I think it would be even more impossible to find suitable case due to the positions of sockets and extra menu buttons on Revision B screen. Maybe Elecrow could provide some insight on available cases?

The PWR will keep on and the ACT will keep blinking when the Raspberry Pi starts up successfully, in case both of the two LEDs keep on, it is possible that the image was burnt incorrectly OR the TF card was in bad contact.

This is a 5" Raspberry Pi LCD touchscreen with 800*480 resolution and 108×64.8mm display area. The product supports Raspberry Pi DSI display interface and comes with a capacitive touch panel on its screen and supports 5 touch points.

The special holes design on the back of the screen is convenient to directly install the Raspberry Pi in the product. There is no need to provide external power for the touchscreen as the Raspberry Pi power supply is adopted. In addition, the screen supports hardware backlight adjustment. The function can be realized by turning the potentiometer on the back of the display.

Now we have this 5-inch TFT display with a touch screen that can provide a high-resolution picture and a large viewing screen for your Raspberry Pi. The display supports any revision of Raspberry Pi and works perfectly for Raspberry Pi B+/ 2B/ 3B. It is the low power consumption for the backlight of the screen. The high 800 x 480 resolution can give you a full-color experience, the touch screen allows users to play easily.

*When working with Raspberry Pi 4, for the system image of Raspberry Pi after 2021-10-30, for example on Bullseye, please modify "dtoverlay = vc4-kms-v3d" to "dtoverlay = vc4-fkms-v3d" in the config file, otherwise it may fail to start. But on Buster, please comment out "dtoverlay = vc4-fkms-V3D" by adding #.

Physical resolution 320x480 with resistive touch control, can be directly connect Raspberry Pi 3 B+ , No additional Power. (Raspberry Pi is not included)

The screen Display support 125MHz SPI signal input, it can display stable without flicker, the refresh rate is about 50fps, it’s enough to play the video and game.

Match PC Protective Case for your screen and Pi, use split design make it easy to install, also match tweezers to make install more easy. White nylon column can help screen maintain balance.

I"m not sure this will help, but had this similar problem on my Raspberry (old 1 Model B) also yesterday. I had not noticed it before because I only recently started using it with X and a monitor. Every time I scrolled in a browser window or even an lxterminal the screen would go blank for 2 seconds seemingly randomly. Changing resolution or tweaking with hdmi settings in /boot/config.txt had no effect whatsoever. It turned out that the problem was related to insufficient power fed to the display adaptor. I had my raspberry connected to my router"s usb slot and obviously this port is only meant for usb sticks that require far less power, perhaps just a few hundred mAs. Connecting the raspberry to a usb port on my pc solved the problem. No more flashing. So try connecting your unit to a different power supply (one rated for at least 1A, preferably more).

First of all, a happy new 2023! I"ll use this occasion to introduce a new type of Sunday blog post: From now on, every now and then, I"ll publish a collection of FAQ around a specific topic, to compile support requests, forum posts, and questions asked in social media or by email...Whatever you are currently celebrating, Christmas, Hanukkah, Jul, Samhain, Festivus, or any other end-of-the-civil-year festivities, I wish you a good time! This December 25th edition of the Nextion Sunday Blog won"t be loaded with complex mathematical theory or hyper-efficient but difficult to understand code snippets. It"s about news and information. Please read below...After two theory-loaded blog posts about handling data array-like in strings (Strings, arrays, and the less known sp(lit)str(ing) function and Strings & arrays - continued) which you are highly recommended to read before continuing here, if you haven"t already, it"s big time to see how things work in practice! We"ll use a string variable as a lookup lookup table containing data of one single wave period and add this repeatedly to a waveform component until it"s full.A few weeks ago, I wrote this article about using a text variable as an array, either an array of strings or an array of numbers, using the covx conversion function in addition for the latter, to extract single elements with the help of the spstr function. It"s a convenient and almost a "one fits all" solution for most use cases and many of the demo projects or the sample code attached to the Nextion Sunday Blog articles made use of it, sometimes even without mentioning it explicitly since it"s almost self-explaining. Then, I got a message from a reader, writing: "... Why then didn"t you use it for the combined sine / cosine lookup table in the flicker free turbo gauge project?"105 editions of the Nextion Sunday blog in a little over two years - time to look back and forth at the same time. Was all the stuff I wrote about interesting for my readers? Is it possible at all to satisfy everybody - hobbyists, makers, and professionals - at the same time? Are people (re-)using the many many HMI demo projects and code snippets? Is anybody interested in the explanation of all the underlying basics like the algorithms for calculating square roots and trigonometric functions with Nextion"s purely integer based language? Are optimized code snippets which allow to save a few milliseconds here and there helpful to other developers?Looking through the different Nextion user groups on social networks, the Nextion user forum and a few not so official but Nextion related forums can be surprising. Sometimes, Nextion newbies ask questions or have issues although the required function is well (in a condensed manner for the experienced developer, I admit) documented on the Nextion Instruction Set page, accessible through the menu of this website. On top of that, there is for sure one of my more than 100 Sunday blog articles which deals not only with that function, but goes often even beyond the usual usage of it. Apparently, I should sometimes move away from always trying to push the limits and listen to the "back to the roots!" calls by my potential readers...

There’s a lot of interest in these little Pi-shaped screens, but there doesn’t seem to be one that is truly “plug n’ play” working straight out of the box.

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 GPIO is accessible via the extra PCB tab below the screen, allowing you to connect any kind of header you want (or none at all). It looks as though this could be cut/snapped off if required, as there are a number of droll holes creating the break for you. It’s subtle and out of the way:

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.

I guess it’s hard to keep us happy – we all want the biggest screen on our Pi, but to achieve that you need to remove the PCB area. A tough balance to strike.

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 AdaFruit screen rolls up at $34.95 – including the screen only (no buttons). You also have to assemble this screen, including soldering the main GPIO connector and taping down the screen element.

Verdict: NeoSec wins this one. Considering the extras you get with it, I personally think it’s a better deal for a ‘screen on Pi’ solution. (and the basic $25 package is clearly much cheaper)

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.

The NeoSec screen doesnt have any support holes, and has no PCB area around the screen (but its a bigger screen, which is more important in my eyes). I can’t see the NeoSec doing well on a Model A without that Ethernet port holding it up. The NeoSec’s PCB doesn’t cover the rear of the screen either, so light comes out on to your Pi.

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.

The NeoSec is a little more traditional with the GPIO, and simply gives you a mirror of the GPIO next to the screen. This is good if you want a simple prototyping access, but perhaps not as ideal if you just want a screen, as it does stick out. It looks as though it can be removed as drill holes indicate an easy option to cut or snap it off.

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.

The NeoSec screen doesn’t have that massive following that AdaFruit does, so finding information already out there can be difficult. Fortunately NeoSec counteract this by providing excellent personal support by email and also regularly on the Raspberry Pi forum.

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 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.

3.5inch RPi LCD (A) and 3.5inch RPi LCD (B) are hardware compatible with each other (uses different driver), and can be mutually substituted in most cases. (A) for low cost ver. while (B) for IPS ver. with better displaying.

Why the LCD doesn"t work with my Raspbian?To use the LCD with the Raspberry Pi official image, driver (SPI touch interface only) should be installed first. Please refer to the user manual.

The PWR will keep on and the ACT will keep blinking when the Raspberry Pi starts up successfully, in case both of the two LEDs keep on, it is possible that the image was burnt incorrectly OR the TF card was in bad contact.Which power supply should I use?It is recommended to use a 5V/3A power adapter for the Raspberry Pi other than USB connection, otherwise the Pi may failed to start up because the PC"s USB port might have not enough power.

Since the first-generation Raspberry Pi released, Waveshare has been working on designing, developing, and producing various fantastic touch LCDs for the Pi. Unfortunately, there are quite a few pirated/knock-off products in the market. They"re usually some poor copies of our early hardware revisions, and comes with none support service.
