Ocular LCD Displays is the latest LCD supplier to pull out of the display market. Consequently, we have been contacted by people asking us for replacement displays once supplied by Ocular USA Displays.

Ocular LCD Displays has moved towards chapter 7. They were located in Texas and began business in 1986. It looks like they ceased delivering displays in mid-November of 2014.

Focus Displays Solutions has been in the LCD business for over fourteen years, in that time we have focused on custom LCDs and replacement LCDs for Ocular USA, Seiko LCDs and Standish Displays.

We not only sell replacement displays, but offer US-based technical support to provide quick responses and US-based inventory. In many cases we can ship you samples the same day you call.

This is not only true for discontinued Ocular LCD Displays, but for LCD suppliers that are still in business, but have discontinued a specific LCD product line.

Whether the LCD has been discontinued by Ocular LCD Displays, Seiko, Standish or other LCD suppliers, Focus Displays has been carrying inventory and offering reverse engineering support to help customers quickly located inventory for their display.

Our technical support people may be able to offer an off-the-shelf standard display with a short lead-time or even zero lead-time. If your Ocular LCD display was a custom, we are able to design and build a solution from your data sheets or from an actual display module.

Focus Displays holds inventory in our Chandler, AZ warehouse and can offer many equivalent displays from stock. If it is necessary for Focus to build a prototype sample, all the LCD glass is shipped via fed ex air, so lead times for large orders are a few weeks and not a few months.

Discovering that your current LCD display manufacture has discontinued your LCD Display is never a welcome surprise. Without a drop in equivalent LCD module you may have to discontinue manufacturing or re-design your product to integrate a new LCD replacement. This can be a frustrating experience, very expensive and time-consuming.

The first step is for the customer to contact Focus Displays at 480-503-4295 and send the data sheets for the LCD that you were using. If you do not have a current data sheet or there is a concern that it may not be accurate, Focus may be able to ‘estimate’ a cost from a photo.

If you are not able to supply a data sheet from Ocular LCD Displays and we are not able to locate it, then the next option is to reverse engineer the display. This is where you would send us two displays (these can be non-working) units that we can take apart and create a schematic and electrical characteristics

Below is our process flow chart to explain the steps necessary to move from concept to full production. More details on developing a custom LCD can be located at

Once a LCD supplier discontinues a display, they tend to remove any documentation from their web site. This lack of data sheets increase the amount of work and lead-time required to generate a quote and build samples. In some cases the old LCD supplier has been purchased by another company and much of their documentation is missing.

If you find that your current module supplier has discontinued your display, contact us for support to help you locate a replacement LCD display. We may have old documentation to reduce your lead-time of locating an equivalent display.

If your displays are custom Ocular LCD displays or it is not a standard off-the-shelf display that we hold in inventory, a tooling fee may be necessary. The tooling fee, also called a NRE (Non-Recurring Engineering), is one-time cost that can run anywhere from $500 to $5,000 dollars.

If you pay the tooling fee, then you own the design. We will only sell this display to you or to who you authorize. If another customer contacts us for the same display, we would forward that customer to you or Focus will contact you and notify you there is a customer looking for your custom LCD.

In the past we have tooled up replacement displays and then directed future business to that customer. The customer that paid us the tooling fee can then purchase the displays from us and resell them to another customer.

There have been times when a customer required a replacement display and we felt that this would be a popular display for us to hold in our inventory and sell to our LCD customers.

Will I be able to order samples to test before I need to place a large production order? The answer is yes, when you pay the one-time tooling cost for the Ocular replacement display, we offer samples at no cost.

Since Focus Displays is building an equivalent display to fill your shortage, why not make improvements on the design? Improvements in LCD technology allow for upgrades such as: Brighter backlights, wider viewing angle, sharper contrast and even lower operating voltages.

Speak to one of our LCD specialist to determine the best solution for you. If need be, we can sell you a display with the brighter backlight configuration for you to test and show your end customer.

DISADVANTAGES OF EL BACKLIGHTS INCLUDEEL backlights require an AC (Alternating current) signal. To generate an AC signal, an inverter must be installed either on the customers board or on the LCD itself.

The popularity of EL Backlights has decreased in the last few years. Over 95% of new product designs no longer incorporate an EL backlight, but instead choose a LED backlight or LED edge-lit configuration. Many products needing a replacement display were manufactured several years ago when EL backlights were common. Your Ocular LCD displays may contain an EL backlight. Many LCD suppliers no longer support EL backlight technology. Focus Displays is able to supply EL backlights, although the MOQ at this time is between 500 and 1K units.

In the past, older LCD technology was limited to a smaller operating temperate range. New types of Nematic fluids and ITO (Indium tin oxide) glass now allow many displays to operate as low as -30C. We are able to offer these wider temperature ranges with minimal cost increase. In many cases, the LCDs we sell are the wide temperature range. There is no extra NRE cost to convert from a standard temperature display to a wide temperature. If your Ocular LCD displays were used in a product that operates outside, we recommend a wide temp. If the product is used indoors, it is possible to use normal temperature. If you do not know where the product operates, we recommend a wide temperature version.

Older LCD technologies were limited in backlight color to yellow/green. Now there is a much wider selection. You can choose a new backlight color to be integrated into your display with minimal or no extra cost. Below are photos showing the different backlight colors. The two most popular colors are Blue/White and Black/White. Additional colors include: yellow/green, grey, blue, white, red, orange, pure green, amber and others.

Focus Displays is able to help reduce or remove hotspots on your older discontinued LCD module by using new diffuser technology, or decreasing the brightness and increasing the quantity of LEDs.

The majority of LCD technologies require an onboard controller driver to be attached to the display. The exception to this is a segmented display that is interfaced with a 4:1 multiplex or direct drive.

Our goal in working to replace your Ocular LCD displays, or any discontinued LCD, is to provide you the same controller driver chip. If the chip on the replacement display is the same as the chip used on your discontinued display, your firmware (aka the customer’s software) will run fine and the characters and fonts will display correctly.

If the new controller is different than the controller used on your Ocular LCD displays, you may need to modify your firmware. When designing the replacement display, we ask the customer to contact their current supplier to clarify which controller chip was used, but if your supplier has discontinued manufacturing of displays, this will not be possible.In this case, send us two of the displays and we will be able to identify which controller was used. If the new controller chip does not work and you are in need of assistance to modify your software, contact Focus Displays and we can put you in touch with a design house that specializes in this type of work.

Focus Display Solutions specializes in supplying replacement LCD Displays for discontinued and obsoleted LCD Display modules. Many times we will have an equivalent display in stock and can sell it to you that day. Other times, we will need to dig deeper to design a custom solution. In either case, our technical support people will work to sell you a display that will meet your needs.

Liquid crystal displays (LCD) are currently replacing the previously dominant cathode ray tubes (CRT) in most vision science applications. While the properties of the CRT technology are widely known among vision scientists, the photometric and temporal properties of LCDs are unfamiliar to many practitioners. We provide the essential theory, present measurements to assess the temporal properties of different LCD panel types, and identify the main determinants of the photometric output. Our measurements demonstrate that the specifications of the manufacturers are insufficient for proper display selection and control for most purposes. Furthermore, we show how several novel display technologies developed to improve fast transitions or the appearance of moving objects may be accompanied by side-effects in some areas of vision research. Finally, we unveil a number of surprising technical deficiencies. The use of LCDs may cause problems in several areas in vision science. Aside from the well-known issue of motion blur, the main problems are the lack of reliable and precise onsets and offsets of displayed stimuli, several undesirable and uncontrolled components of the photometric output, and input lags which make LCDs problematic for real-time applications. As a result, LCDs require extensive individual measurements prior to applications in vision science.

Liquid crystal display (LCD) is a flat panel display that uses the light modulating properties of liquid crystals. Liquid crystals do not produce light directly, instead using a backlight or reflector to produce images in colour or monochrome.
