If you have ever wondered what it took to make your own custom graphic LCD from scratch, this video from [Applied Science] is worth a watch. It’s concise and to the point, while still telling you what you need to know should you be interested in rolling your own. There is also a related video which goes into much more detail about experimenting with LCD technology.

[Applied Science] used microscope slides and parts purchased online to make an LCD that displays a custom graphic when activated. The only step that home experimenters might have trouble following is coating the glass slides with a clear conductive layer, which in the video is done via a process called sputtering to deposit a thin film. You don’t need to do this yourself, though. Pre-coated glass is readily available online. (Search for Indium-Tin Oxide or ‘ITO’ coated glass.)

The LCD consists of a layer of liquid crystal suspended between two layers of conductive glass. An electrical field is used to change the orientation of crystals in the suspension, which modulate the light passing through them. Polarizing filters result in a sharp contrast and therefore a visible image. To show a particular shape, some of the conductive coating is removed from one of the layers in the shape of the desired image. The process [Applied Science] uses to do this is nearly identical to etching a custom PCB.

Parts of LCD technology can be quite hackable. Neither of these videos are brand-new, either. Have any of you taken on the challenge of DIY LCD displays? We’ve seen experiments with electrochromatic glass using old LCD displays, as well as experiments in playing with polarized light to hide secret messages on LCD screens.

The process to take your LCD idea from a concept to having prototype samples in hand is simple and requires just the few steps listed below. (Download PDF)

In many cases, FocusLCDs’ lead time for custom LCD samples is as little as 6-7 weeks after you approve our counter drawings and data sheet. This lead time increases by 4-6 weeks between November to early February due to Chinese New year. Standard production orders for custom displays have a lead time of 10-12 weeks, which can increase by 2-4 weeks during Chinese New year.

Focus Display Solutions offers several LCD technologies. The majority of these displays can be customized to fit your need. Below is a short introduction to each type of LCD.

Ultra-Wide Viewing Display (UWVD) is a new technology that is named after one of its most notable characteristics – it is viewable from all angles. In addition to the viewing angle, this technology provides a better contrast than other options and can allow for multiple colors. Call one of our design specialists today to see if UWVD is the right technology for you.

Thin-Film-Transistor Liquid Crystal Displays (TFTs) are perhaps the most encountered display technology we see daily. Often seen in cell phones, tablets, cameras and countless other devices, this technology offers several hundreds of thousands of colors with a high pixel count to offer supreme visual clarity. In addition, all TFTs are available off the shelf with resistive and capacitive touch panel options.

Character LCDs have been around since the 1950s and are still very common. These displays offer 256 selectable characters and are available with several different font tables to show a variety of languages. They are most commonly known for their ease of programming wide variety of sizes, character arrays and colors.

To create an LCD, you take two pieces ofpolarized glass. A special polymer that creates microscopic grooves in the surface is rubbed on the side of the glass that does not have the polarizing film on it. The grooves must be in the same direction as the polarizing film. You then add a coating of nematic liquid crystals to one of the filters. The grooves will cause the first layer of molecules to align with the filter"s orientation. Then add the second piece of glass with the polarizing film at a right angle to the first piece. Each successive layer of TN molecules will gradually twist until the uppermost layer is at a 90-degree angle to the bottom, matching the polarized glass filters.

As light strikes the first filter, it is polarized. The molecules in each layer then guide the light they receive to the next layer. As the light passes through the liquid crystal layers, the molecules also change the light"s plane of vibration to match their own angle. When the light reaches the far side of the liquid crystal substance, it vibrates at the same angle as the final layer of molecules. If the final layer is matched up with the second polarized glass filter, then the light will pass through.

If we apply an electric charge to liquid crystal molecules, they untwist. When they straighten out, they change the angle of the light passing through them so that it no longer matches the angle of the top polarizing filter. Consequently, no light can pass through that area of the LCD, which makes that area darker than the surrounding areas.

Building a simple LCD is easier than you think. Your start with the sandwich of glass and liquid crystals described above and add two transparent electrodes to it. For example, imagine that you want to create the simplest possible LCD with just a single rectangular electrode on it. The layers would look like this:

The LCD needed to do this job is very basic. It has a mirror (A) in back, which makes it reflective. Then, we add a piece of glass (B) with a polarizing film on the bottom side, and a common electrode plane (C) made of indium-tin oxide on top. A common electrode plane covers the entire area of the LCD. Above that is the layer of liquid crystal substance (D). Next comes another piece of glass (E) with an electrode in the shape of the rectangle on the bottom and, on top, another polarizing film (F), at a right angle to the first one.

The electrode is hooked up to a power source like a battery. When there is no current, light entering through the front of the LCD will simply hit the mirror and bounce right back out. But when the battery supplies current to the electrodes, the liquid crystals between the common-plane electrode and the electrode shaped like a rectangle untwist and block the light in that region from passing through. That makes the LCD show the rectangle as a black area.
