Definitions

  • Display units for displaying images are nowadays designed, among other things, with light-emitting diodes (LEDs).
  • LEDs light-emitting diodes
  • a very large number of pixels eg LEDs
  • a correspondingly large number of supply lines is necessary. If the wiring is carried out in the manner of a matrix with row and column leads, z. B. with n leads n 2/4 LEDs (n straight).
  • the invention has for its object to provide a display with LEDs, which is composed of modules and which is wired such that the number of leads required to control the display ge as possible ring is. This object is achieved by the features of the present claim 1.
  • the essence of the invention is that the arrangement according to the invention is composed of two types of modules, that the first type of module is wired according to a certain principle, that the second type of module is wired like a matrix, and that the overall arrangement is again according to the particular one Principle is wired.
  • This principle and the rest of the invention are explained in more detail below using an exemplary embodiment.
  • the six row lines a 1 .... a 6 are used as supply lines.
  • the six column lines b l ..b 6 are present in the first type of module, so that the number of row lines is equal to the number of column lines.
  • the first module type has a matrix-like wiring, in which each row line is connected to one and only one column line, namely a 1 with b l , a 2 with b 2 , a 3 with b 3 , a 4 connected to b 4 , a 5 connected to b 5 and a 6 connected to b 6 .
  • each crossing point of row and column lines at which the crossing row and column lines are not connected to one another ie at all crossing points with the exception of the crossing points K 11 , K 22 ' K 33' K 44 , K 55 and K 66 'each have a light-emitting diode.
  • Figure 2 shows the second module type, which is constructed according to the known principle of the matrix circuit.
  • the second module type has as many row and column lines as the first module type.
  • LEDs are present at each crossing point of row and column lines, one connection of which is connected to the row line present at the crossing point and the other connection of which is connected to the column line existing at the crossing point.
  • the second module type as shown in FIG. 2, generally no row lines are connected to column lines.
  • the second module type of Figure 2 has 6 row and column lines and 36 diodes.
  • the 24 lines led out to the left are used to control this display.
  • the display of Figure 3 is the manner of a square (4 x 4) matrix from the two types of modules assembled such that the four slide g onalelem e n th M 11, M 22 'M 33 and M44 of the array of modules of the first type 1 and the remaining twelve elements of the matrix consist of modules of the second type 2.
  • the module M 11 is connected to its module M 12 adjacent in the row in such a way that each row line a 1 to a 6 is connected to the same row line of the adjacent module.
  • the module M 11 is connected to its module M 21 adjacent in the column in such a way that each column line b 1 to b 6 is connected to the same column line of the adjacent module.
  • all modules of each row are M 11 to M 14 ' M 21 to M 24 , M 31 to M 34 and M 41 to M 44 and all modules of each column M 11 to M 41 , M 12 to M 42 , M 13 to M 43 and M 14 to M 44 connected to each other.
  • any number of modules can be combined to form a display in an analogous manner be switched.
  • the number of leads of the overall display is mn, and the number of diodes that can be controlled with it is mn. (Mn-l), corresponding to the total number of LEDs.
