Definitions
- the present invention relates to illuminated signs in which the display of the information, preferably variable, appears on a support by the selection or by the combination of individual semiconductor elements comprising components suitable for emission. of light, for example light-emitting diodes.
- This so-called luminous display comprises an electronic process in which the characters of the information are formed on a fixed or mobile support, by the selective and / or combined supply of light-emitting diodes ordered in a matrix on said support.
- the originality of this process resides in the fact that the characters of the information scroll from right to left along the length of the rows of the matrix due to a selective supply of diodes, repeated successively column by column.
- This process is implemented by an electronic device, in accordance with the invention and in which the characters of the variable information scroll from right to left on a medium, by selective feeding and / or combined ordinate emitting diodes in a N. matrix with m rows and n columns (M m, n)
- a t el device is characterized in that the aforesaid support consists of horizontal juxtaposition of n / 8 cards diodes ordinate matrices M ' m, 8 ; each of these cards has m shift registers arranged one per matrix line.
- Each of the m inputs of these shift registers receives the same signal which validates the corresponding line of the first column of the previous card and the eight outputs of each of said registers are successively connected to the diodes forming the eight matrix elements of the line which is assigned to him.
- the characters of the variable information are displayed by sub-matrices M "with seven lines and five columns, usable in particular for an alphanumeric display.
- all the time bases of all the shift registers of the same support are supplied by a single clock, adjustable to control the speed of scrolling of the information.
- any information will scroll over said length by successive shifting from one column of diodes supplied to the next, from right to left.
- This display mode therefore makes it possible not to restrict the message of the information whose parameters - are transmitted on the inputs of the shift registers of the first card, by an appropriate control member in the form of '' a keyboard, a memory, etc ...
- the selective supply of the aforesaid diodes is validated by the low state of one of the outputs of the shift registers thus offering a very good contrast to the display of the information scrolling on the support.
- This display is also accompanied by a good viewing angle offered by the three modes of presentation of the matrix elements, in accordance with the invention and adapted to three different heights of character. These three modes are given without limitation and are illustrated by the appended drawings below representing, from front views, three diode cards ordered in matrix M ′ 7,8 .
- the first mode represented in FIG. 1a and which adapts to a minimum height of the characters of the information, consists in symbolizing the matrix element by a single diode D.
- the second mode represented in FIG. 1b and which adapts to a height of the characters 2.5 times greater than that of the preceding ones, consists in symbolizing the matrix element by four diodes D arranged in a diamond shape.
- the third mode shown in Figure lc and which adapts to a height of the characters 4 times greater than that of the characters of the first mode, consists in symbolizing the element of matrix by seven diodes D arranged at the six vertices and in the center of a regular hexagon.
- a preferential characteristic of the invention intended to improve the reading of information consists in directing opposite the point of the diamonds or hexagons drawn by two elements of linear matrix juxtaposed.
- the electronic device of the invention is in the form of a support 10 cut from an insulating material and on which the various components of said device are installed. These components are constituted in particular by light-emitting diodes D projecting from the visible face of the support and ordered according to the first mode of presentation illustrated in FIG. 1a, in a matrix M 7, n ,
- the support 10 is constituted by the juxtaposition of n / 8 diode cards 20 of diodes D ordered in a matrix M ′ 7,8 and is inserted in a rectangular box (not shown) one of the faces is transparent to reveal the luminous display by diodes D.
- This box is connected to a control member (memory keyboard, etc.) intended to program the parameters of the information message.
- Each diode D of the lines of the matrix M ' 7,8 is connected between a voltage supply V and one of the eight outputs (S 1 , S 2 , S 3 , ... S 8 ) of the shift registers R 1 , R 2 , ... R 7 corresponding respectively to lines 1, 2, ... 7.
- the outputs S 8 of the seven shift registers of the card 20 are connected to the seven inputs E 1 , ... E 7 of the shift registers of the following card .
- the information message can be presented on the cards 20 of the support 10 in two different ways.
- the first consists in making the message appear progressively on the support from right to left by setting high the voltage supply V of the diodes D throughout the duration of scrolling of the information.
- the second consists in sending the variable information from the diodes D of the first column of the first card 20 to the last column of the nth card, during a period when the voltage supply V of the diodes is in the low state and where the adjustable clock H is in service, then the aforementioned information appears on the sign for an adjustable period when the voltage supply V of the diodes is in the high state and the adjustable clock H is not in service.
