What are the reasons and solutions for the white screen when the industrial control LCD screen is turned on?

LCD industrial control LCD screen is now one of the devices that can be seen everywhere. Industrial industries have gradually used industrial control LCD screens, and industrial control LCD screens occasionally have white screens. So, how to solve the white screen failure of industrial control LCD screen? It is a very common phenomenon that the LCD industrial control LCD screen turns on the black screen or blue screen. Black screen and blue screen are problems with the system or hardware, and the white screen failure of the display screen when it turns on is generally a failure of the LCD industrial control LCD screen itself.

Causes of LCD industrial control LCD screen failure:

The white screen failure of LCD industrial control LCD screen may be caused by three aspects: problems with the LCD panel drive circuit, problems with the LCD panel power supply circuit, poor contact of the screen line, and problems with the motherboard control circuit.

If the industrial control LCD screen can be turned on normally, it means that the backlight and high-voltage generation circuit are working properly, indicating that the LCD panel has not received the drive signal; if the screen disappears after shutting down, and then a white screen occurs, it may be a problem with the power board.

This means that no matter whether it is turned on or off, as long as the power is plugged in, the high-voltage generation circuit is in working condition and the backlight source is always lit. That is to say, the high-voltage generating circuit is no longer controlled by the switch, that is, the switching signal sent by the motherboard to the high-voltage generating circuit has lost control. Since the switching signal sent by the motherboard microprocessor is generally controlled by several transistors, the fault may be that the transistor that controls the switching signal is damaged.

LCD industrial control LCD screen fault repair:

1. Remove the shell and check whether the screen line interface is loose or not connected properly.

2. Then turn on the power switch and use a multimeter to measure whether the power supply voltage of the screen line interface is normal. If the power supply voltage is normal, check whether the timing signal and drive signal in the LCD panel drive circuit are normal; if not, then check whether the fuse resistor or fuse inductor near the output end of the screen line is open or damaged. If damaged, replace the damaged components.

3. If the fuse resistor or fuse inductor near the output end of the screen line is normal, then check whether the output voltage of the DC-DC voltage conversion circuit that powers the LCD industrial control LCD screen is normal. If the output voltage is abnormal, check the fuse resistor, PWM controller, switch tube, inductor coil, filter capacitor and other components in this power supply circuit, and then replace the damaged components.

4. If the output voltage of the DC-DC voltage conversion circuit is normal, there are damaged capacitors and other components between the output of the DC-DC voltage conversion circuit and the screen line interface. Check and replace the damaged components. 5. If the power supply voltage of the screen line interface is normal, then check whether the timing signal and drive signal in the LCD panel drive circuit are normal. If not, check the output signal, input signal and power supply voltage of the chip that generates this signal to determine whether the drive chip is damaged. If damaged, replace it.

Newxie prototype testing success 🦃🥧

We just had a turkey nap and are now back to work. These vertical-mount 1.14" IPS TFT displays have 240 x 135 pixels and are 'stackable' horizontally on a breadboard or perfboard. There are just enough pins to control the TFT and backlight, so if you want to individually control each display, just have them share the SPI and DC pins, then have a unique chip select pin for each. These could make for cute 'flip' display simulations or faux nixie bulbs. The prototypes work fine; we just need to adjust the slot size. The panelized PCBs can be booked, and there is pie.

im. so curious to know what the tests would be? (from this post)

Oh my god I love this question!!

Evan is someone deeply curious about the human body. I always think about him having a sketchbook where he just... Draws limbs and hearts and whatever comes to his mind, people he loves and cares about with their guts opened. He's just curious and worried about anything that can happen.

When Barty showed up hurt by his father for the first time he lost his fucking mind. He's not to nurture but he is to protect and own, and for Barty he learns to be all of it.

So All the nine yards: complete blood count (cbc), basic metabolic panel (bmp), comprehensive metabolic panel (cmp), lipid panel, thyroid function tests (tfts), hemoglobin a1c (hba1c), c-reactive protein (crp), vitamin and mineral levels, urinalysis, microalbumin test, chest x-ray, abdominal ultrasound, bone density scan (dexa), electrocardiogram (ecg/ekg), echocardiogram, stress test, prostate-specific antigen (psa) test, colonoscopy, fecal occult blood test (fobt), hiv test, hepatitis panel (a, b, c), sexually transmitted infection (sti) tests, lung function tests (spirometry), vision test, hearing test, electrolyte panel, dental x-rays (bitewing, panoramic, or periapical), oral examination (teeth, gums, and soft tissues), periodontal probing (gum health assessment), plaque and tartar check, tooth decay (cavity) detection, occlusion (bite) analysis, oral cancer screening, salivary testing (bacteria or ph levels), tmj (temporomandibular joint) evaluation, fluoride level testing

As I said, ALL the nine yards

At first Barty thinks it's a little over the top, I mean, he wasnt sick, beaten up and with a serious history of child neglect, yes, but he's more than happy to do anything Evie tells him to. He wants him to lay down and stay still? Got it. Run like a lab rat? Consider it done. Get his blood draw? Barty's already rolling his sleeve. But somewhere in the middle of it he just felt so... Looked out for. He's pretty sure no one would care with him as much to lose time doing something like this. And Evie personally is the responsible for all his tests. All of them. He never lets Barty alone and even though it hurts and his bedside manners are the worst, Barty feels his heat warm.

Also, it turn them both on, for different reasons but it does, which might be as well just what they need. And it kind of becomes routine, every few months Evan decides it's time enough and picks some of the tests to re-do.

But I love to imagine Evan laying in bed like a teenage girl writing all the results with drawings and notes, happy like a puppy.

Im not sure if this was what you were looking out for when you asked but I hope I could answer it nicely, loved your profile :))

[crewfu]

Hi ! I'm new around here, do you or anyone else have a crewfu primer to get to know the main people a bit more? Thank you! Xo

this is a big ask but i will do my best:

So we will start with “Crewfu” itself. I think the more used/accepted name for the group is the Morning Lobby. They are a group of streamers/content creators that met through playing Among Us. I'm not 100% on the start date but it was some time in Oct/Nov 2020 - April/May 2021. They had a reunion in June 2022 and continue to play Among Us every Wednesday since. I'll write a short synopsis for each current regular but the otv and friends wiki has a great list of the people who played in the morning lobbies. I also included some links to clips of some of the streamers that I really like.

Crewfu vods/videos I would recommend:

Crewfu panel at twitchcon 2022 edited / full vod

Crewfu plays pico park edited: hafu Dumbdog / full vod (steve)

Hafu’s birthday stream full vod

Hafu: She is the crew’s Mom. She set up the original morning lobbies daily for months. She’s a legend in the gaming community and has been streaming/playing games competitively for over 10 years. Choose any competitive game over this time period and Hafu has probably mastered it. She is married to another streamer called dogdog and they live in Las Vegas with their dog Jubbs.

dakotaz (dk): One of the og members of the morning lobby. He helped set up the lobbies with Hafu at the start due to the frustration of trying to find and play in lobbies at the height of Among Us popularity. Currently streams Fortnite almost daily. He has an alt stream where he sometimes streams Among Us and Valorant and any other games he feels like. He hits those, he's in his 30s, and he's petty all the time. He briefly lived in Vegas but he is a true Florida man and moved back after a short time.

5up: His twitter bio says “rank 1 among us player” He was a rival to Hafu in the og lobbies and was known for his big brain Among Us plays. He also acted as the substitute teacher during the original lobby run and held things together after hafu stopped playing among us in 2021. He commissioned a team to create a custom Among Us map called the submarine map. He plays a lot of competitive games currently like League of Legends, Valorant, TFT as well as MCC. He also travels a lot and he has a lot of friends in many different streaming circles like OTV&F, the minecraft community, etc.

stevesuptic: He was “poached” from a ChilledChaos lobby where he met Hafu and Dumbdog for the first time. He impressed Hafu with not only how funny he was but also with how bad he was at the game. He makes and produces his own music under the artist name "SUGR?" He's been a part of too many youtube channels to list but is probably most well known for Sugar Pine 7. He currently streams valorant and variety content pretty much daily. In May of 2023 he announced that he is roommates with Janet/xChocoBars, another member of the Morning Lobby. In July 2023 he got his own kitten named Olympus or Oly for short.

DumbDog: Despite his name he is generally known for being good at most games. He met Hafu through NorthernLion on the NLSS. He was a semi-regular participant in the original morning lobbies but I think he’s the only person who has been in every single lobby since the reunion. He recently bought a house and adopted a cute husky puppy named Artemis or Artie for short. He is a frequent member of the variety lobbies and plays with Steve and their group almost daily. He is a furry and as part of a sub goal he commissioned a fursuit and it was finished this year. 

xChocoBars or Janet- She is a Canadian variety streamer and a regular in both current and original lobbies.  She plays lots of group games with friends and is often addicted to certain games like APEX and TFT and streams them a lot. She has 2 cats named Hazel and Baton and recently became roommates with Steve.

Angelskimi or Kimi (formerly known as plushys): She is an ASMR artist who was a regular in the og lobbies and plays almost weekly now. She is a pretty irregular streamer but does upload on her ASMR youtube channel weekly. Despite her claims of being “so angel” she is an innuendo queen. She lives in LA with her dog Pix and her cat Snowball.

Ellum: He is one half of daft and dafter with Koji being the other half. He is one of the regulars from the UK. He calls himself the smoothest brain on twitch which may or may not be true. He streams variety games on most weekdays. He lives in London with his girlfriend (CaptainPuffy) and they have a corgi named Pudding together.

koji: He is the other half of daft and dafter. He is known for being a very wholesome streamer. His content oscillates from really cozy games to horror with occasional group gaming streams with friends. He is vegan and lives with his longtime girlfriend Abby and their 2 dogs Miso and Bugs.

Smajor / Smajor1995 / dangthatsalongname / Scott: He currently plays quite frequently in the morning lobby but his specialty outside of that is minecraft content. He is on the Empires server, organizes MCC, the life series, etc. I personally watch more of his youtube content than his streams. He lives in England but he is from Scotland.

Junkyard129: He is a new regular to the morning lobbies and has been playing every week for the last several months. He is the oldest person in the lobby and is often the butt of a lot of jokes because of it. He has probably been creating content longer than anyone else in the lobby as youtube says his first video was uploaded 16 years ago!! Currently streams variety gaming solo and with the Chilled group quite often. He also has regular streams from his woodworking shop where he makes cutting boards, coasters, etc to sell. He has a special dance that he performs when he gets raided.

vGumiho: She is a variety v-tuber who currently plays both in the morning lobby and with the Steve variety game group. She started becoming a more frequent regular when the crew started playing Valorant but plays most weeks for the Among Us lobbies currently. She has a dog named Kazu. She organizes ppsat lobbies which used to be weekly but are less frequent now.

Ovilee: She is an esports commentator who currently plays with the morning lobby most weeks. She also streams and she presented the morning lobby panel at twitch con.

A Practical Guide to Customizing TFT LCD Displays for Embedded Projects

When designing an embedded system, picking the right display module is more than a technical choice — it directly shapes how users interact with your product.

From medical devices and HMIs to industrial controllers and smart panels, standard TFT LCD modules may not always be enough. That’s where custom displays come in — offering flexibility in electrical interface, mechanical layout, and visual performance.

This guide covers the five key areas you should consider when customizing a TFT LCD for your embedded project.

1. FPC Layout and Pin Mapping

The Flexible Printed Circuit (FPC) connects your LCD module to the mainboard, and in custom designs, this interface is often the first thing to change.

Ask yourself:

Do you need a uniquely shaped or angled FPC to fit inside your housing?

Are there ICs, resistors, or other components on the backlight or CTP that require mechanical clearance?

Is your SBC’s connector pinout compatible with the LCD’s FPC layout?

A mismatch here can lead to signal errors, mechanical stress, or even damage to components.

2. Backlight Brightness and Color Temperature

Not all embedded devices live under the same lighting.

If your product is used outdoors or in industrial lighting, consider high-brightness backlights (≥800 nits). For environments where aesthetics and color warmth matter (like smart mirrors or indoor kiosks), choose the right LED color temperature:

3000K (Warm White): Soft, suitable for medical or ambient lighting

5000K (Neutral White): Balanced tone, accurate colors

6500K+ (Cool White): Sharper, more industrial feel

A poorly lit display can make a great device feel underwhelming.

3. Touch Panel Shape and Bonding Options

If your display includes a touch interface, customizing the Capacitive Touch Panel (CTP) is critical.

Typical customizations include:

Round corners, logo cutouts, button holes

Bonding methods:

Optical bonding: Improves visibility, reduces reflections, stronger seal

Air bonding: More affordable and easier to assemble

The bonding method directly impacts touch accuracy, display clarity, and long-term reliability.

4. Surface Treatments: AG, AR, and AF

For devices exposed to bright light or frequent finger contact, display surface treatments make a noticeable difference.

AG (Anti-Glare): Scatters reflected light, improving readability

AR (Anti-Reflection): Enhances contrast in sunlight or strong lighting

AF (Anti-Fingerprint): Reduces smudges, improves touch feel

Combining AG+AF is a common choice for public-facing touchscreen displays.
