segmented lcd displays free sample

Looking to take your project to the next level in terms of functionality and appearance? A custom LCD display might be the thing that gets you there, at least compared to the dot-matrix or seven-segment displays that anyone and their uncle can buy from the usual sources for pennies. But how does one create such a thing, and what are the costs involved? As is so often the case these days, it’s simpler and cheaper than you think, and [Dave Jones] has a great primer on designing and specifying custom LCDs.

We’re amazed at how low the barrier to entry into custom electronics has become, and even if you don’t need a custom LCD, at these prices it’s tempting to order one just because you can. Of course, you can also build your own LCD display completely from scratch too.

A 7-segment display is commonly used in electronic display devices for decimal numbers from 0 to 9 and in some cases, basic characters. The use of light-emitting diodes (LEDs) in seven-segment displays made it more popular, whereas of late liquid crystal displays (LCD) have also come into use.

Whereas LCD uses liquid crystal properties for displaying and does not emit light directly. These LEDs or LCDs are used to display the required numeral or alphabet.

Custom Segment Liquid Crystal Displays are seen in products that measure the PH level of swimming pools, monitors used to measure specific gases in a mine, or in thermometers used to see if a child is running a fever. They are one of the oldest display technologies, but still one of the most popular.

Segment LCDs, also called static displays or glass-only displays, are constructed of two pieces of ITO (Indium tin oxide) glass with a twisted nematic fluid sandwiched in between. A static display is a segment display with one pin for every one segment.

These displays are still one of the most popular technologies in use and the majority of them are custom. Many people think the process of designing a custom segment liquid crystal display is complicated and too complex to be understood except for a few experienced people. But after designing custom LCDs for over 14 years, it can be said that just about anyone can select the best options for their product.

In other words, you don’t have to be an engineer, or have a PHD from MIT to design a custom LCD for your application. So instead of offering a list of technical terms and equations, these are the different options available.

Although Segment displays are an older technology, it is still one of the most popular. After all, they cannot display all the colors of a TFT or OLED like what can be seen on a cell phone and tablet.

The tooling fee for a custom display is the lowest of all the technologies and allows the customer to receive a LCD that is manufactured to the exact dimensions requested, including custom icons and segments.

Focus LCDs offers a one-time NRE (Non-recurring engineering) or tooling fee. This includes all design, technical support, and samples. A PDF showing an overview of our tooling process can be found by clicking here: Custom LCD flowchart

Segment displays require less power than other display technology such as TFT, OLED, and UWVD. This makes these LCDs ideal for applications that are battery powered or solar powered. They require the lowest power to drive, an estimated 2uA per centimeter squared. Glass only displays (no backlight and no controller) require an estimated 10% of the power that is required for a LED backlight. In other words, a static display without a backlight will draw around 1mA; the same display with a LED backlight will demand from 10mA up to 25mA. Most displays can be driven at 3.3V or 5V since microprocessors can operate at both voltages. 3.3V is becoming more popular since two double ‘AA’ batteries can produce between 3.0V and 3.3V.

A segment is any line, dot or symbol that can be turned on and off independently. The photo below is of a segment LCD that contains numbers, a small clock symbol, the word ‘Jul’, and the letters ‘PM.’

There are four numbers in the above LCD (0 8 4 7) all are seven segments. In other words the ‘0’ has seven segments, the ‘8’ has seven segments and so on. Each number has seven independent segments. Each segment can be turned on and off independently to create other numbers and some letters such as E, F C and others. This is an example of a ‘seven’ segment. But there are some letters that a seven segment cannot display such as the letter ‘M’ or ‘V’. In this case a fourteen segment configuration can be used.

An icon is a small symbol or set of words that is only one segment. In other words, when the segment is ‘on,’ the full word or symbol turns on. When it is “off,” the word or symbol turns off. In the photo above: the clocksymbol is one segment, the word ‘JUL’ is one segment, the letters FOCUSLCDS.COM are one segment and the letters ‘PM’ are one segment.

It is possible to burn a segment into the glass so that it is always “on”. In this case, the ‘FOCUSLCDS.COM’ has been burned into the glass and can always be seen by the customer even when the power is “off”. Some customers will have their company name burned into the glass.

Segment displays earn the name ‘glass only display’ because the majority of them are glass with small metal leads attached to both sides of the display. However, it is possible to add a PCB (Printed Circuit Board) or a controller driver chip (IC). The construction of the display is similar to that of a sandwich. You take two pieces of glass, glue one piece on top of the other, than inject a fluid between the two pieces of glass. In the drawing below you see a side view of a segment display. The glass on top is smaller than the glass on the bottom. This is to allow room for the pins.

Segment LCDs, like all LCD display technologies, operate best between specific temperature ranges. You choose the temperature ranges that it will operate in. There are two standard configurations: normal temperature and wide temperature. The wider the temperature range, the more expensive the display.

The standard operating temperature range for a segment LCD is 0C to 50C. It is possible to build the display with a different fluid that will allow it to operate from -30C to 80C (F). With the addition of a heater, the display can operate down to -50C.

VATN (BTN) – Vertically Aligned Twisted Nematic is only available in negative mode (light colored letters on a dark/black background). VATN displays produce very bright segments and can be easily read.

A 10 digit, with thousand marks ("), digital point, the symbols M, E and (-). Intended to mimic traditional LCD displays found in common calculators from the eighties and after but with all the complexity of the backplanes, segments, duty cycles and polarity handled by a 92 segment LCD driver with I2C interface which memory maps a segment to a bit.

I wanted to create an eighties looking calculator to learn about LCDs, matrix keyboards, fixed point math. I found a library that does the heavy lifting of transforming keypresses into display output and I couldn"t find an off the shelf LCD with:
