Today, there are several kinds of display technologies used in the automobile. Of these technologies, the Vacuum Fluorescent Display has the following advantages:
-
1.
Excellent readability under high ambient light conditions
-
2.
High reliability under severe environmental conditions
-
3.
Multicolor capability
-
4.
Large glass size
-
5.
Graphics flexibility
As a result, the Vacuum Fluorescent Display technology is the major type of display technology used in the automobile application.
A design trend in the industry is toward the use of graphic displays because of the need to display more information, and to reduce the cost and space factor.
Until recently, vacuum fluorescent graphic displays of large area and high resolution had been limited by the lower brightness due to the low duty factor driving condition.
The development of the triple anode dot matrix display has solved the problem of the small duty factor, and has made it possible to satisfy the brightness requirements for the graphics display.
