Discontinued LCD suppliers
We receive calls asking for replacement Seiko LCD displays. Seiko is only one of several LCD display manufactures who have pulled the plug on production of Liquid Crystal Displays. In the last few years, several suppliers of Custom LCD panels have discontinued many of their liquid crystal Display offerings. Some of these display suppliers have gone out of business while others have obsoleted lower profit modules. The list of these suppliers includes, but is not limited to, Seiko LCD Displays, AND LCD Modules, Standish LCDs, Orion LCD manufacture and others.Why are suppliers of custom LCD panels and standard LCD modules pulling the plug?
LCD suppliers, who manufacture both custom LCD panels and standard LCD modules, have only so much capacity to build LCDs. In other words, they can only manufacture a certain amount of LCDs every day. Once they reach that level, they have no choice but to turn away business This forces them to reject low profit LCDs in favor of higher profit displays. Older LCD technology no longer carries the earnings that are now available with newer displays. Another critical factor in the decision to discontinue LCD production is the acute labor shortage in China. This highly populated country now has more available jobs then there are employees to fill them. This produces a smaller work force and therefore a smaller number of displays that can be manufactured. A third reason that LCD’s are being discontinued is that the company simply goes out of business. If the supplier is carrying too much debt or finds that they can make more money in other products, they simply close their doors.Custom LCD panels to replace Seiko
Seiko LCD Displays’ has discontinued many of their Character LCD display modules. Focus Display Solutions is able to supply equivalent Seiko LCD Replacements. Many of these alphanumeric Seiko LCDs are standard off-the-shelf modules that do not require a tooling fee. But others may require a tooling investment to design and build a custom LCD panel that is a direct cross to their discontinued Seiko LCD. We carry sample stock of many of the obsolete Seiko character LCDs and in many cases are able to quote you a cost the same day you contact us. If you do require a non-standard display, lead time for custom Liquid Crystal Displays are between six to seven weeks for prototype samples and an additional six to seven weeks for production quantities.Seiko LCD panel part numbers

What makes us different supplier of Custom LCD panels?
It is becoming increasingly more challenging for US-based manufactures to compete against foreign/off-shore manufactures. They need to daily review their process and look for ways to reduce cost, waste and delays. One of the great challenges they face is the discontinuance of critical components such as an LCD. We have been in the custom LCD business since 2001 and in that time we have learned a great deal of lessons to help our customers reduce cost, shorten time to market and deal with LCD’s that have been discontinued. What makes us different from other LCD suppliers is that we specialize in designing custom LCDs to replace displays that have been discontinued by other suppliers.

Increasing the Sharpness on a Custom LCD Display

Does your custom LCD display need a sharper contrast???
…No Problem
Oftentimes it is possible to improve the sharpness, or contrast, on your current LCD display without having to redesign your current product. Many of these improvements can be realized without the tooling fees necessary to build a custom LCD display module. Before we move forward, I need to clarify that the type of displays we are talking about are monochrome LCDs and not TFT or OLED’s. Monochrome displays include character, graphic and segment displays.
Character Alphanumeric LCD Display
Monochrome Graphic LCD module
Segment LCD Display
Two easy fixes to improve contrast
1. Adjusting contrast voltage
A monochrome LCD display unitizes three different voltages: Ground (zero volts), the displays max voltage (3V, 3.3V or 5 volt) and the contrast-adjust voltage. The contrast-adjust voltage performs the same function as the lens on a camera. By adjusting the lens, the user can bring the image into perfect sharpness. Contrast-adjust voltage performs a similar function by adjusting the voltage to provide a sharper image. The contrast voltage is set before your product is shipped to the customer, but changes in temperature can affect the sharpness requiring the voltage to be modified in the field.2. Switching fluid type
Monochrome LCD displays are built by trapping a Nematic fluid between two layers of glass. Switching the fluid in your monochrome LCD from one fluid to another can increase the sharpness of your display. This nematic fluid is referred to as Twisted Nematic (TN) since it has the ability to twist or rotate when voltage is applied to the LCD. When the display is powered up, the fluid rotates sideways and blocks light from passing through. When the power is turned off, the fluid rotates back to its original state and allows light to pass through. The more the fluid in your LCD display can twist, the sharper the image. There are three common types of TN fluid: Twisted Nematic (TN), Super Twisted Nematic (STN) and Film Super Twisted Nematic (FSTN). TN fluids are similar to the three grade of gasoline for your car; the better the fluid, the more it is able to twist and the higher its cost. LCD Display suppliers are able switch between fluids without a tooling cost or a higher Minimum Order Quantity (MOQ). Twisted Nematic (TN) The fluid with the least twist and lowest cost is Twisted Nematic (TN). TN cannot rotate as much as STN and FSTN and therefore produces a display with the least amount of clarity. TN is not a bad option if you are building a cost sensitive product where clarity is not critical. Products that use TN include pagers, digital watches and many gas pumps. Super Twisted Nematic (STN) STN is the medium grade fluid and is the most popular of the three because if offers a good performance at an affordable cost. Products that use a STN fluid include credit card readers, home alarm systems and scales. Film Super Twisted Nematic (FSTN) FSTN is the high end or ‘premium super unleaded’ fluid. It offers the greatest amount of twist and therefore the greatest sharpness. The cost increase from STN to FSTN ranges from 8% to 12% more expensive. If ultimate sharpness is critical, FSTN is the way to go. Products that incorporate FSTN include medical devices, avionics and high-end audio.

LCD Touch Panel Technology of the Future

LCD Touch Panels that identify the user
But what does the future of LCD touch panels hold? One new touch panel technology makes use of a capacitive sensor system with the ability to differentiate between users. A team of researchers working at Disney Research, yes Mickey Mouse, is funding research on Human-Computer Interactions. Developers are making use of a technique called swept frequency capacitive sensing. The basic idea is that the interface measures the impedance of each user, with respect to ground, through a range of AC frequencies. The system is then able to differentiate which user is making contact with the touch panel.Possible applications
Although this technology is not yet in production, the uses of it could be integrated into such industries as access control, time and attendance, multi-player games and even automotive.
One idea would be to integrate the new technology into your company’s software. The program would contain logic able to identify the user through the touch screen. It would then allow each user specific access to specific menus and options. The warehouse person could access shipping and receiving menus only, while accounting would access aging reports, chart of accounts and checking balances. The controller or owner of the company would have full access to all menus. One advantage of this is the elimination of passwords.
The automotive industry could allow user preferences to be unique to each driver. When driver “A” touches the color monitor located on the dashboard; the automobile would automatically adjust radio station selections, dashboard brightness and blue tooth settings that are unique to driver “A”. The automobile’s configuration would change to meet the needs of driver B or C as soon as the touch screen identifies the new driver.
With the release of Windows 8 and its ability to interface with touch panel technology, home computers could be configured to allow limited access to specific programs and web pages for children and full unlimited access for adults.
Although this option is still in the future, there may be applications in your industry that would benefit from the ability to identify which user is accessing the touch panel.
At the current time we offer a variety of different interfaces, including resistive, Q-Touch and multi-touch capacitive touch screens.
Custom LCD’s with custom Touch Panels
It is possible to design and build a custom LCD integrated with a custom touch panel. Possible options would include size of touch screen, type of controller and anti-glare finishes. The OEM (Original Equipment Manufacturers) would also be able to select a protective material to allow users to use alcohol and other cleaning materials.2013 Chinese New Year Creates Longer Lead Time for LCD Displays

Longer lead times to begin in December
Labor shortages at manufacturing facilities will begin as early as December and increase rapidly into January with a complete shut down the first week of February. This is due to the number of employees who will leave their jobs early and travel home for longer periods of time. The reason for this early exodus of employees is that this year they are in a position to take more time away from work. Workers, who need to travel further to get home, could start their leave of absence in December and may not return until late February. As the Chinese’s New Year draws closer, more and more workers will leave their positions. In some cases, factory personnel will be away from production lines for two to three months. Many times these laborers do not return back to their previous job and relocate to employers closer to their home. This requires LCD manufactures to locate and train new workers; an expensive and time consuming expenditure that only adds to the lead time. Adding to this headache is that most manufacturing plants in the US shut down for seven to fourteen days between Christmas and New Year.Labor shortages are already so acute in many Chinese industrial zones that factories struggle to find enough people to operate their assembly lines. Factories often pay fees to agents who try to recruit workers arriving on long-haul buses and trains from distant provinces. – New York Times March 30, 2012 (see article)
What is the Solution?
Don’t procrastinate, order your displays now and don’t wait until your MRP tells you to order. Place your PO now and claim your place in the manufacturing queue. If your worse-case scenario of “committing too soon” is the consequence of your LCD modules arriving in the states thirty or sixty days too early, then no problem, we will hold your inventory in the US and ship when you need it. Unlike the majority of our competitors, all our international shipments, both samples and production quantities, are shipped fed ex air. That means we receive your product within five to seven days after it leaves the factory. Compared to shipping by boat which can add an additional four to eight weeks lead time. Two main reasons for delays in shipments via surface is the time for the boat to travel on water and the delay waiting for the shipping container to be full before it can ship.
