#lcd clock

[kalikai]

I repaired this sick ass digital clock I got from a thrift store very cheaply a few years ago. It's just a floating LCD panel and I think it looks so frigging amazing. (Really makes me think of that cool Dutch YouTuber, Posy, and his love of LCD panels. (And I'm like "hell yeah!! There's so much beauty in the mundane!!! Just look how frigging cool this clock is!!"))

Anyhoo, it wasn't working when I got it. Probably why it was so cheap.

It has a little on/off switch on the back, but nothing would happen when you flipped it, but sometimes if you held its solar panel under a very bright light the clock would turn on

...for one second

before turning off again

and then back on again.

Very rhythmically.

So there was still some life left in the old girl... somewhere... 🤔

Unscrew the back of it and have a look see.

Discover a pair of circuit boards, one of which has a cr2032 coin cell clamped onto it. Hooray, a Vital Clue!

Fortunately, I have one of those batteries lying around. A second spare from when I replaced the batteries in some Digimon v-pets.

So I replace it.

Aaaaand nothing happens...

:(

Next step: fully disassemble the clock to look for More Clues.

Discover that its LCD panel isn't wired in to anything. There's just a row of teeny tiny contacts along its base which press up against a matching row of teeny tiny contacts along its control board, held together by the frame of the clock and a kind of thin pink foam buffer ring around the contacts. Very cool!

(Like two mouths kissing but only one of them has any lips. 😆)

Examine the two circuit boards under a loup. Maybe there's a visibly-broken component!

(I hope there's a visibly-broken component, else I have to dig out my multimeter and start systematically testing them one by one)

(I hope there aren't any visibly-broken components. If it's the quartz crystal or one of the two capacitors, then I might be able to replace it, because those are regular-sized, through-hole, components; but if it's one of the surface-mount resistors then I'd have to scrap the whole clock, because I just don't have the tools, experience, or know-how to deal with those microscopic little guys... :/ )

There aren't any visibly-broken components. Phew, but also consternation, because now what?

But hmm, there are some teeeeny tiny white flecks of crusty residue here and there over the circuit boards... I guess the old battery must have leaked at some point?

I gently scrape them off with the tip of a very fine pair of tweezers and then reassemble the clock enough to test it.

(LCD panel & solar panel back into front-frame, control board back over them to hold them into place and make contact with the LCD; everything else [coin-cell daughterboard, piezo buzzer, and the user-input buttons] dangling free in the breeze Winnie-The-Pooh-style)

It turns on! It chirps out a happy little song of high-pitched beeps!! It blinks "12:00" at me!!!

I fully reassemble the clock with a song in my heart and set its time and date.

Goddamn this clock looks so cool. 🥰

Achieving Sunlight Readability in Industrial LCD Screens

A common challenge in outdoor and brightly lit industrial settings is display washout. Standard screens become unreadable under direct sunlight, hindering productivity and safety. A sunlight readable display is specifically engineered to solve this problem. Achieving this clarity involves a combination of high-powered backlighting and advanced optical treatments.

The Core Metric: High Brightness (Luminance)

The most critical factor is brightness, measured in nits (candelas per square meter). A typical office monitor has 250-350 nits. A sunlight readable display starts at 1000 nits and can exceed 2500 nits for direct sunlight applications. This intense luminance overpowers ambient light, ensuring the image remains visible. However, high brightness alone is not a complete solution and must be paired with other technologies to be effective and efficient.

Combating Glare: Anti-Reflective and Anti-Glare Coatings

Glare from the sun or bright indoor lights can render a screen useless. High brightness LCD screens employ special coatings on the glass surface:

Anti-Glare (AG): Etches the glass with a fine haze to diffuse reflected light, breaking up direct reflections.

Anti-Reflective (AR): Applies a microscopic coating to the glass to reduce the amount of light that reflects off the surface.

These coatings are often used together to maximize clarity and minimize eye strain for operators.

The Game Changer: Optical Bonding

As mentioned in the previous article, optical bonding is a paramount technology for sunlight readability. By filling the air gap between the touch panel and the LCD with resin, internal reflections are drastically reduced. This allows more of the screen's native light to pass through to the viewer's eyes, making the image appear significantly brighter and more vibrant, even without increasing power consumption. For any industrial monitor used in variable lighting, optical bonding is a key differentiator.

Technology in Action

Sunlight readable industrial monitors are essential for:

Outdoor Kiosks: Ticket vending, information booths.

Transportation: Fleet management, railway control systems.

Agriculture: In-cab displays for heavy machinery.

Construction: Equipment operating terminals.

Conclusion: Clarity in Any Environment

Specifying a sunlight readable display requires careful consideration of brightness, coatings, and bonding technology. By understanding these elements, you can select an industrial LCD screen that guarantees clear, actionable information for operators, regardless of the lighting conditions, thereby enhancing both efficiency and safety.

i keep thinking about a digital (segmented) clock with this as the case

it would look so stupid but i would love it
