Their main products, including 10.1" TFT LCD display with LED backlight, self-ordering-kiosks, smart card reader, thermal printer, embedded motherboard and all-in-one panel PC, which focus on providing interactive-kiosk solutions..

A large share of our business originates from customers who need our LCD reverse engineering services for a replacement display module. Their current supplier has discontinued the LCD series or no longer supplies Liquid Crystal Displays.

A short time ago a customer contacted our technical engineering support department and asked if we could develop a 40x2 custom character LCD display to replace a module that their previous supplier had discontinued. They required our LCD reverse engineering services to provide a drop-in equivalent including EL backlight and exact pin-out.

This display is much larger than most character LCD displays with a length of 9.8 inches and a width of 1.5 inches. Its character height is a little over ½ inch.

Although the standard display configuration is with an EL (Electro-luminescent) backlight, the character display can be manufactured with a LED (Light Emitting Diode) backlight.

Half-life is the amount of time before the backlight is half (or 50%) as bright as when it was first turned on. This is not the number of hours to when the backlight burns out.

The standard half-life of an EL backlight is 3K hours versus a LED backlight with a half-life of 50K to 90K hours (depending on driving current and desired brightness)

EL backlights are AC (Alternating Current) driven which means there needs to be an inverter on the LCD or on the customers PCB to convert the DC (Direct Current) to AC. This adds cost and requires real estate on the PCB.

EL backlights now have a higher minimum order quantity of 500 displays per build. Focus is able to hold inventory in our Chandler warehouse if necessary.

EL backlights are limited in their size, when a larger backlight is required, a CCFL (Cold Cathode Fluorescent Lamp) is required. The challenge is that CCFL backlights in LCDs have been phased out.

The brightness of the backlight is measured in ‘nits’. As a general rule, one Nit is equal to the light produced by one candle. (It’s a bit more complicated than that, but it works out the same).

LEDs can create hot and cold spots under the LCD glass. Most of the time the light can be ‘smoothed’ out with a diffuser, but the brighter the LED backlight is driven, the greater the chances of hot spots.

Character displays can be built in a variety of background and backlight colors. The photos below present a sampling of different options. Available colors include:

If the display needs to operate to a lower temperature than -30C, it would be necessary to add a heater. Contact Focus Displays for help with your custom LCD heater.

Below are photos of two character displays in both positive and negative mode. Positive mode is standard, but the character LCD can be built as negative mode

The negative mode version requires the backlight to be on for the display to be readable, and is not the best solution for battery and solar powered products.

FSTN monochrome LCD displays contains a retardation film applied to the STN display to produce a black and white display. The film produces a higher contrast and wider viewing angle than STN or TN.

STN monochrome LCDs require less power and are less expensive to manufacture than TFT’s. They produce a sharper contrast then TN but less sharp then FSTN. Basic color options are Gray, Blue and Yellow/Green (most common). Other colors are available through the use of filters.

TN monochrome LCDs is the lowest cost of the three options. Contrast is not as sharp as STN and FSTN. Primary color options are black letters on a gray background. Other colors are available through the use of filters.

As mentioned at the beginning of the article. Focus Displays is able to design and build an equivalent character LCD to take the place of a discontinued display. Sometimes it may require LCD reverse engineering services.

Many times a one-time tooling or NRE (Non-Recurring Engineering) fee is required. This tooling fee is much lower for segment, character and monochrome graphic displays than it is for OLEDs (Organic light emitting diode) and TFT"s (thin-film-transistor).

The first step is for the customer to send Focus Displays the datasheets for the LCD they were using. If the customer does not have a current datasheet or there is a concern that it may not be accurate, Focus may be able to ‘estimate’ a cost from a photo.

Most LCD displays require some type of on-board controller driver processor. There are many companies that manufacture LCD IC’s. The challenge is that a controller from one company may not be 100% compatible with the controller from a second company.

If Focus is not able to locate a source for the current controller, Focus will build the prototype samples with an ‘equivalent’ IC. Chances are that the equivalent will work, but if not, the customer may be forced to modify their firmware (customer written software/code).
