Using a Heater to operate an LCD in a cold temperature

Monday, August 16th, 2010

As LCD modules become colder, the fluid reaches a freezing point. The colder the LCD display module becomes the slower the response time.

TN LCD’s will operate to -30 C. STN LCD’s will operate to -20 C. At this temperature it may require 5 seconds or more for the display to respond.

To improve (reduce) response time of a liquid crystal display it may become necessary to add a heater.

Focus Displays does not carry LCD module heaters. One source is http://www.conflux.se/index.html

All Focus Display monochrome LCD modules can be purchased in TN, STN or FSTN.

Have you been Factory swapped?

Friday, June 18th, 2010

The more you order, the lower your cost. This has always been true. The cost of 10K liquid crystal displays (lcd display modules) would be 5% or 7% less expensive than if you ordered 100 displays. This is also true for custom STN displays, FSTN displays and TN numeric displays. But lately we have seen some suppliers offer a price break by as much as 30% to 40%.

One example of this is when one supplier dropped the price by 35% when the customer increased the quantity from 10K to 50K displays. As it turned out the supplier quoted the 10K units to be manufactured in China and the 50K quantity to be manufactured in Cambodia.

A supplier could send you a sample from a factory in one country and then ship you samples from a different factory. This could cause problems later if there are any differences between the sample and production lcd module units.

The next time you receive a quote with a very large price break in character LCD modules, segment displays, and monochrome graphic LCD’s, make sure that the units will be produced by the same manufacture as the sample you receive.
