Problems solved by technology

[0014] Although the fourteen-segment coded VFD can provide good support for standard ASCII characters such as numbers and English letters, it still cannot achieve good display for non-standard ASCII characters, such as Latin, German, French, etc.
[0015] In order for VFD to support the display of non-standard ASCII characters in languages ​​such as German and French, some manufacturers often need to add more digital tubes to support more complex characters, and need to develop more complex display codes to support these non-standard ASCII characters. Will result in huge hardware costs and R & D investment

Abstract

An embodiment of the invention discloses a method for displaying characters on a vacuum fluorescent display, which includes: analyzing to obtain a code of a character according to a preset coding method; determining the pre-divided character type of the character according to the character code obtained by analyzing; if the character belonging to display-supporting non-standard ASCII (American standard code for information interchange) characters, converting the display-supporting non-standard ASCII character into a display-supporting standard ASCII character according to a preset converting rule, and displaying the display-supporting standard ASCII character on the vacuum fluorescent display; and if the character belonging to the display-supporting standard ASCII characters, directly displaying the display-supporting standard ASCII character on the vacuum fluorescent display. The embodiment of the invention further discloses a device for displaying characters on the vacuum fluorescent display. Using the method and the device for displaying characters on the vacuum fluorescent display can display the non-standard ASCII characters on the vacuum fluorescent display in a current ASCII character displaying way.

Description

technical field [0001] The invention relates to the field of digital display, in particular to a method and device for displaying characters on a vacuum fluorescent display. Background technique [0002] VFD (Vacuum Fluorescent Display, vacuum fluorescent display) uses electrons to hit the phosphor on the glass substrate to emit light, and the bright spots on the VFD are combined in various ways to display characters, numbers and specific icons. Because when VFD is used as a display, not only the displayed characters are clear and bright, but also the power consumption is low, so VFD is widely used in electronic equipment such as household appliances, instruments and automation equipment to display digital information (such as temperature), Character information (such as name) and some markup indication information. On set-top boxes, VFD has also become an increasingly mainstream display output method. [0003] Existing VFD usually adopts two segmented coding methods: eigh...
