Definitions

  • the invention relates to a fluorescent segment display, in particular for a stove control, according to claim 1.
  • hearth-related Data such as the temperature of the oven, or setting data, such as. a certain cooking program, or also hearth-neutral data, such as a time that is visually conveyed. It is common to have a separate display field for each display to be provided with a neon segment display.
  • a fluorescent segment display is known from WO-A-96/02904.
  • segment displays execute and / or control differently.
  • Driver blocks or the like used, which also functions take over the pure control of segments go out and in particular protocols for a full screen segment display.
  • a low-cost and nevertheless universally applicable for different segment displays Unit control can be achieved in that the Individual segments of the segment displays depending on the control from a simple slave microcontroller, the one Interface to a master controller with specification of a Interface protocol with the individual segments to be controlled having; the one kept free of additional functions Slave microcontrollers only control the Individual segments of the respective segment display, the necessary information about which segment to head for the interface protocol from the master microcontroller is communicated.
  • the interface protocol points no links in the sense of a full-screen storage only the segments are listed individually and stored with regard to their individual control. Consequently is the slave microcontroller as a simple electronic Control unit universal for all segment displays can be used with comparable MUX and display refresh rates, as far as the maximum controllable number of segments is not is exceeded.
  • FIG. 1 shows a block diagram in the construction of an inventive Control of a neon letter segment display L; the individual segments of the illuminated segment display L are controlled by a slave microcontroller SMC, the via an interface SS from a master microcontroller MMC an interface protocol with the individual control commands for the individually controlled individual segments is conveyed.
  • the segment display L1 shows e.g. the time display an electronic stove control, the individual segments S1 are individually controlled as line segments, such that this results in a full screen with the numbers of the time.
  • FIG. 3 shows a segment display L2 for a temperature display an electronic stove control, whereby again individual segments S2 are controlled in the form of line segments in such a way that it results in a full screen with the numbers of a temperature display results.
  • FIG. 4 shows a segment display L3 with a DOT matrix, at which is controlled as individual segments S3 point segments that there is a clear text for a cooking program results.
  • LEDs are in particular the segment displays L1, L2 and L3 (Light Emission Diode) displays or LCD (Liquid Crystal Display) or VFD (Vacuum Fluorescent Display) intended.
  • L1, L2 and L3 Light Emission Diode
  • LCD Liquid Crystal Display
  • VFD Vauum Fluorescent Display
