Definitions

  • the invention relates to a device for controlling an optoelectronic display device which has dot matrix display elements, according to the preamble of claim 1.
  • the invention also relates to a method for controlling such an opto-electronic display device.
  • Alphanumeric characters can be displayed in a dot matrix or segment representation. Both types of display have basic advantages depending on the type of alphanumeric characters to be displayed, on legibility and on other criteria. It may therefore be desirable to display a first group of data, which is referred to below as input data, with a dot matrix representation and a second group of data (input data) with a segment representation.
  • the first group of input data is date information, such as the days of the week
  • time information i.e. the time.
  • Liquid crystal display elements are particularly suitable for display in segment display. But it also comes Vacuum fluorescent display elements and other types of optoelectronic display elements into consideration.
  • control unit which comprises a character generator and a driver acting on the display elements.
  • the character generator contains in detail a character table in which the character set to be displayed is stored in an addressable manner.
  • the character table in which the characters to be displayed with dot matrix display elements are stored one memory location each contains a matrix point of the character to be displayed.
  • the matrix point data for each character to be displayed are controlled by a sequence control and read out from the character table and fed to the dot matrix display elements via the driver.
  • the dot matrix display elements can be controlled for a 5 x 7 dot matrix with a multiplex rate of 1: 7 in time-division multiplexing.
  • the input data which in the present case are the input data of the second group, are recoded with a program so that the segments are controlled according to the alphanumeric characters to be displayed .
  • the segment display elements can be acted upon by a driver in time-division multiplex operation, which usually includes a multiplex rate of 1: 3, since one back electrode can be assigned to 3 front electrodes.
  • a driver in time-division multiplex operation, which usually includes a multiplex rate of 1: 3, since one back electrode can be assigned to 3 front electrodes.
  • the program must therefore be able to convert the entire alphanumeric character set into a large number of segment data which are to be transferred to the control unit, ie the driver.
  • the segment data and the matrix point data are formed from the input data in fundamentally different ways. This results in a great deal of effort and further operational disadvantages, in particular in the transmission of the recoded data.
  • the usual different multiplex rates with which dot matrix display elements and segment display elements are operated have a disruptive consequence, which can be seen from the outside, that both displays present themselves with different contrasts.
  • the present invention has for its object to improve the processing of the recoded input data for a parallel, practically simultaneous representation of alphanumeric characters with dot matrix display elements and segment display elements, in particular to reduce the technical effort required for this, to simplify the transmission of the recoded input data and a prerequisite to ensure that the alphanumeric characters have the same contrast in dot matrix representation and in segment representation.
  • the essence of the invention is that to control the dot matrix display elements and the segment display elements are not two different principles and systems are used, but that a uniform point matrix controller is assumed, which is modified in such a way that it can also be used to control the segment display elements. There is therefore no need for a separate program for forming the segment data.
  • the segment data are generated in basically the same way as the point matrix data.
  • the expansion of the character table provided for this requires only a small additional effort, all the more since essentially the same sequence control can be used to operate the control unit that contains the character table.
  • the prerequisite is that the part of the character table which should contain the segment data in accordance with the segment character set is programmable.
  • ROM memories can be used for this, in particular PROM or EPROM memories.
  • the segment data like the dot matrix data, are fed to the display device via the same driver which is designed to operate the segment display elements.
  • the same high multiplex rate of, for example, 1: 7 (and higher) can be used for the segment representation with the sequence control as is usually the case for the dot matrix representation.
  • the dot matrix display elements and the segment display elements can thus be read comfortably with the same contrast.
  • the control or addressing of the control unit with the character table can be carried out by means of the input data recoded in the same way for the dot matrix representation and for the segment representation.
  • This data can thus be transmitted by a uniform data telegram, which contains the recoded input data of the first group and the second group. Complex measures for the parallel transmission of this data of the first and second group are eliminated, as are complex means for separating the data.
  • the data telegram with the data for the dot matrix display elements and for the segment display elements can be fed into an input memory of the control unit. From this, the data can be read out serially and displayed with the dot matrix display elements and segment display elements assigned as intended, by activating these elements synchronously with the assigned segment data and matrix point data read out from the character matrix.
  • the character table for the segment data which has been expanded in accordance with the invention, requires a change in the address management compared to the normal dot matrix character table.
  • the memory locations for the segment data can be addressed with addresses that have the same component (e.g. lower bits) as for addressing the point matrix data, but also a different component (higher bits).
  • the memory elements of the character table assigned to a character each contain the segment data assigned to the electrodes for activating the segment display elements to activate the segments that can be activated in columns and lines. Fewer memory elements are used for this than for controlling a 5 x 7-point matrix.
  • Claims 3 and 4 contain the procedural aspect of the invention for controlling the optoelectronic display device of the type mentioned in the preamble of claim 1 if, in addition, segment display elements are to be displayed in parallel as desired.
  • the parallel display means that both the segment display elements and the dot matrix display elements can be read simultaneously.
  • the control of these display elements takes place serially with a high repetition frequency.
  • the input data are recoded in basically the same way to form address data to which the character table of the character generator responds.
  • the dot matrix data and the segment data are thus read out from the character table in the order of the address data, processed in the character generator and increasingly supplied to the display elements via the driver. Similar processes therefore take place both for the segment display and for the dot matrix display, as a result of which the outlay for carrying out the method is low and the operational reliability is high.
  • the assignment of the address data transmitted with the data telegram for the segment data and for the point matrix data to the display elements takes place in a relatively simple manner in that the data telegram - if necessary cached - is read into the address part of the character table synchronously with the activation of the display elements and processed in the character generator .
  • 1 denotes an input for feeding so-called input data into a general data processing system 2, which are to be displayed.
  • the input data can be, for example, binary-coded data of a digital clock module and in this case contain time information that is to be displayed in a segment representation and date information that is to be made visible in a dot matrix representation.
  • the general data processing system can include an organization for reading in the data, for identifying the data, for processing the data, for classifying the data according to the type of representation - segment or point matrix representation - and can be constructed conventionally.
  • the time to be represented in binary form is formed from the time information, for example by integrating time pulses.
  • the current day of the week is derived from the date information.
  • the input data with the date information, which are to be displayed in a dot matrix representation are referred to as input data of the first group and the input data of the time information, which is to be made visible in segment representation, as input data of the second group.
  • a converter 3 is connected to the general data processing system 2 for the processed data of the first group.
  • the converter 3 contains an address table 4 for the supply of the character set to be displayed in a dot matrix representation.
  • the converter 3 converts the code of the processed input data of the first group so that a control unit to be discussed - FIG. 2 - can be addressed with the data. This is where the converted data from first group in an output memory 7, in which a data message is compiled.
  • the code of the processed input data of the second group is converted by means of a converter 5 in basically the same way for addressing the control unit in FIG. 2 as the processed input data of the first group.
  • the converter 5 contains an address board for the character set in segment representation, which is contained in the control unit. With the converter 5, an address is thus selected from the address table 6, which corresponds to processed time information in order to display the time in the usual decimal representation with the downstream means.
  • the addresses which are formed from the first group of the input data and the addresses which are generated from the second group of the input data are combined in a data telegram in the output memory.
  • FIG. 2 connects to the interface 8 and essentially comprises a liquid crystal display (LCD display) 9 and a control unit, generally designated 10, for operating the display.
  • LCD display liquid crystal display
  • control unit 10 for operating the display.
  • the LCD display has four segment display elements 11-14 for displaying the time of day.
  • a dot matrix display element 15 is used to visualize the day of the week.
  • the control unit comprises in particular an input memory 16 for receiving the data telegram with addresses for the point matrix data to be selected for the weekday to be displayed and for the segment data to be selected for visualizing the current time with the LCD display device 9.
  • the supply of the dot matrix data for the characters possible in the dot matrix representation is contained in a conventional dot matrix character table, which forms an essential part of the character table 17.
  • the dot matrix character table is supplemented with an additional, similarly addressable and structured table part with the segment data which form the segment character set which can be represented. Details of the character table 17 result from the figure 3 to be discussed below.
  • the character table 17 forms a character generator with a sequence control, not shown, which generates signals on an output channel 18 which, by means of the respectively activated display elements 11-15, the To make the alphanumeric characters to be displayed visible, the signals on the output channel 18 are amplified in a driver 19, which also belongs to the control unit 10.
  • a driver 19 which also belongs to the control unit 10.
  • each alphanumeric character has an area with 7 memory elements (corresponds to lines to be controlled) and 5 stored information (corresponds to columns to be controlled), see Figure 4.
  • the memory areas of the character table can be addressed with a character word that consists of the Addresses 36-47 and 20-35 are composed.
  • the character table shown in FIG. 3 is conventionally provided with matrix point data with regard to the memory areas which can be addressed with the addresses 36-41 and 45 (partially), 46 and 47. This part of the character table is also referred to as the matrix point character table.
  • the additional part of the character table comprises the columns of memory areas (partially) addressable under the reference numerals 42-44 and 45, in each of which segment data of an alphanumeric character are programmed. At least this additional part must be programmable.
  • the coding of the segment data in a memory area is shown in FIG. 4, specifically with reference to a segment representation element in FIG. 5, which has seven segments in a conventional arrangement.
  • the segment display element in FIG. 5 includes column electrode connections S1, S2 and S3 and row electrode connections Z1, Z2, Z3, Z4 and Z5.
  • the number 1 means segment activated; and the number 0 means segment not activated.
  • the representation in FIG. 4 thus shows the coded information of the segment data for the representation of the number 2.
  • a data telegram in the input memory 16, which contains the addresses for displaying the information of the first group of input data and for displaying the second group of input data, is essentially processed as follows: the addresses are read out serially from the input memory, and the display elements 11 are synchronized with it - 15 activated, ie prepared for display. A representation element is therefore effective for each address word.
  • One of the memory areas of the character table in FIG. 3 that can be addressed in a matrix-like manner is queried with the respective queried address word.
  • the time matrix control converts characters in the dot matrix representation at an address to the dot matrix data that are used to convert the dot matrix display element 15 at a multiplex rate of 1: 7, for example.
  • the alphanumeric characters Mo for "Monday" appear in the dot matrix display element 15.
  • the decimal numbers for the visualization of the time with the segment display elements 11-14 are made in such a way that for each decimal digit a range of the additional part of the table is addressed under one of the addresses 42-44 combined with one of the addresses 20-35.
  • the segment data shown, for example, in FIG. 4 are then read out for each area and converted into signals, which apply the corresponding electrode pairs to voltage via the driver 19, see FIG. 5.
  • the electrodes are also acted upon in multiplex operation at the same multiplex rate as for Operation of the dot matrix display element 15 so that the time, in the example 12.30 p.m., and the day of the week, in the example Mo, are presented as a uniform appearance.
