Long Life / High Reliability LCD's
LXD specializes in the manufacture of extremely long life LCD's for those applications in which service life and reliable performance outweigh all other considerations. Our long life LCD's, with temperature ranges as low as -55oC and as high as 122oC, are designed for outdoor applications and others where extremes of temperature and humidity are encountered. These include gasoline pumps, marine instruments, oil exploration devices, and many others.
Our processes have been designed to eliminate two major types of display failures. These include "functional" failures that can be traced to defects in
materials or process, and failures that are characteristic of a display's end of life behavior.
The incidence rate of both types of defects in normal manufacturing is not high, but since the cost of replacing a display can be twenty times its
initial cost, and even higher in some outdoor applications, many users prefer an assured longer service life. The higher purchase price usually results
in a lower cost of ownership.
"Functional" field failures, typified by seal failures, shorts, open segments, and ghosting, have been eliminated through manufacturing controls. Each
type of defect was studied independently. Conditions or practices that permitted it to occur have been changed or eliminated. Early
"end-of-life" failures (loss of alignment, bloating, high current) have also been eliminated through the use of state-of-the-art materials and the
development of improved chemical processing and formulations.
