Workshop de Electronic Paper Toys organizado pelo Laboratório de Criação Digital - Audiência Zero e pela Casa do Conhecimento - Câmara de Vila Verde no dia 18 de Abril de 2012. Electronic Paper Toys é um projecto open source dos laboratórios Audiência Zero dedicado à exploração da fusão do papel com electrónica.
This Sharp Aquos 52" LCD on a portable stand provides a great image for Polycom VSX 7000 videoconferencing or for watching the latest Blu-ray Disc movies.
Mi nuevo monitor LCD, no habia razon realmente necesaria por el cual cambiar mi CRT, solamente estaba enamorado de esta tecnologia, unos USD 276 me salio el chiste, y en 6 meses recien dejare de pagarlo!!! Ouch!!
Blogged in The Woodwork: Hoodman woes.
This is a picture of my two Hoodman H-D70 FlipUp LCD caps. The one on the left broke due to my negligence during a hike in Oregon (the left cover and spring disappeared in the water due under regular use, but I had a nervous habit where I open and close the thing constantly). The one on the right failed on it’s first use and was defectively made near the hinge (or assembled incorrectly).
Strangely the areas that were weak/defective areas on one are rock solid on the other.
I used Dave McNally’s low tech product shot setup to take this photo. I dodged the photo to the whiteground using levels but then reduced the opacity it to return a hint of shadow.

Step one, pick up 50d
Step two, grin from ear to ear
Step three, freak out the sales assisstant by fondling and cuddling said 50d
Step four, grin from ear to ear
Step five, jump up and down and do a little dance around Harvey Normans
And I haven't even picked it up yet!!!
Managed to sweet talk HN down $300 bucks to the cheapest price I could find online, so am currently having LCD daydreams, im not shitting you, that LCD is fucking incredible.
Ive never been much of a chimper in the past. All of that will change in just two more sleeps!! I feel giddy, ecstatic, im dancing around my house, and still.. grinning from ear to ear. this has been a long time coming, so forgive me!!! I deserve this!!!!!

I bought a very cheap LCD alarm clock and took it apart, intending to shoehorn it inside the DMM case. The LCD was connected directly to the tiny circuit board via a conductive elastomer strip. There wasn't space to do that in the DMM case, so I realised I'd have to improvise a ribbon cable and press one end against the contacts on the circuit board and the other against the LCD glass. Here you see a test run. The LCD is working. I've also connected the buttons on the DMM's front panel to the appropriate contacts on the clock's circuit board so I can use them to set the time. Some of the switches were "sticky" -- when pressed in they'd stay in, another press would release them into the off position. I found I could remove a small detent wire and make them "momentary" instead.
But I was never very comfortable with the ribbon cable approach, it seemed too fiddly. I also had a hard time coming up with a good way to mount the LCD. So I made no progress.
And that's where it sat for a looong time, in the"too hard" box.
Digital Signage LCD with Integrated Media Player
Sun Group has responded to market demand for affordable high quality Digital Advertising Display SUN-SG8 7Inch, 8Inch, 10.4Inch, 15Inch, 17Inch and 19Inch.
The Sun Group taking into consideration the needs of small and large size digital signage advertising applications. These wall-mountable LCDs are the perfect solution for retail store pos displays. The integrated Media Player gives advertisers the ability to display content without the need of any external devices or signals. It supports CFI, II/MD/SM/MS/MS pro/SD/MMC card formats outputs JPEG images and MPEG videos to the screen and is easy-to-use. When strategically placing these displays throughout a small retail store, an increase of traffic can be driven for specific products. The display can inform customers directly of product availability and promotional opportunities, increasing customer awareness. Using the LCD in a public venue enables advertisers to reach their audience with the latest advertisements, and also can be used to display pertinent information for events. Restaurants can set up a slideshow of entrees, as well as inform customers of the latest specials. Hospitals use the displays in waiting rooms to inform their patients of the latest medical procedures, technologies. The content displayed on screen is easily changed via USB Update function. Built-in real-time clock and calendar. Automatic power on/off time.
a complete stand alone all-in-one signage solution, highlighted by an innovative integation of an LCD display monitor with a full-function digital media player in an elegant yet heavy-duty construction chassis. These fully solid state and highly reliable products were primarily designed for resellers, dealers, and integrators offering Digital Signage solutions in today's modern and contemporary applications.
A liquid crystal display (LCD) is a thin, flat electronic visual display that uses the light modulating properties of liquid crystals (LCs). LCs do not emit light directly.
The earliest discovery leading to the development of LCD technology, the discovery of liquid crystals, dates from 1888.
Each pixel of an LCD typically consists of a layer of molecules aligned between two transparent electrodes, and two polarizing filters, the axes of transmission of which are (in most of the cases) perpendicular to each other. With no actual liquid crystal between the polarizing filters, light passing through the first filter would be blocked by the second (crossed) polarizer. In most of the cases the liquid crystal has double refraction.[citation needed]
The surface of the electrodes that are in contact with the liquid crystal material are treated so as to align the liquid crystal molecules in a particular direction. This treatment typically consists of a thin polymer layer that is unidirectionally rubbed using, for example, a cloth. The direction of the liquid crystal alignment is then defined by the direction of rubbing. Electrodes are made of a transparent conductor called Indium Tin Oxide (ITO).
Before applying an electric field, the orientation of the liquid crystal molecules is determined by the alignment at the surfaces of electrodes. In a twisted nematic device (still the most common liquid crystal device), the surface alignment directions at the two electrodes are perpendicular to each other, and so the molecules arrange themselves in a helical structure, or twist. This reduces the rotation of the polarization of the incident light, and the device appears grey. If the applied voltage is large enough, the liquid crystal molecules in the center of the layer are almost completely untwisted and the polarization of the incident light is not rotated as it passes through the liquid crystal layer. This light will then be mainly polarized perpendicular to the second filter, and thus be blocked and the pixel will appear black. By controlling the voltage applied across the liquid crystal layer in each pixel, light can be allowed to pass through in varying amounts thus constituting different levels of gray. This electric field also controls (reduces) the double refraction properties of the liquid crystal.
The optical effect of a twisted nematic device in the voltage-on state is far less dependent on variations in the device thickness than that in the voltage-off state. Because of this, these devices are usually operated between crossed polarizers such that they appear bright with no voltage (the eye is much more sensitive to variations in the dark state than the bright state). These devices can also be operated between parallel polarizers, in which case the bright and dark states are reversed. The voltage-off dark state in this configuration appears blotchy, however, because of small variations of thickness across the device.
Both the liquid crystal material and the alignment layer material contain ionic compounds. If an electric field of one particular polarity is applied for a long period of time, this ionic material is attracted to the surfaces and degrades the device performance. This is avoided either by applying an alternating current or by reversing the polarity of the electric field as the device is addressed (the response of the liquid crystal layer is identical, regardless of the polarity of the applied field).
