Definitions

  • the invention relates to a method for adjusting optical data reproduction in electronic paper and to an optical data reproducing apparatus for carrying out the method.
  • Control circuits integrated into the electronic paper which comprise transistors for defining pixels, send control signals from a control device to the individual pixels which, in the case of a black-and-white representation, align electronic ink particles such that a desired white or black side of the pixels Particles facing a viewer of the film.
  • the electronic paper is housed in a receiving housing, which also contains the electronic control device for driving the pixels.
  • the electronic paper sheet is to be rolled out of the receiving housing to provide an optical display surface for data to be displayed.
  • the present invention seeks to provide a method for adjusting an optical data reproduction in electronic paper and to present an optical data reproducing apparatus, with which the method is feasible.
  • step c A particularly important feature of this method is laid down in step c), according to which, starting from the detected dimensions of a currently available display surface, data processing takes place which is designed such that the data can be reproduced essentially completely on the display surface.
  • a required, to be determined Auslaufer the electronic paper is detected in step a).
  • a preferred embodiment of the method provides, in the event that the data contains text data, that a character font adapted to the currently available display area is selected.
  • a font size can be adapted in this way to the playback area.
  • step c) is performed at the request of the user of the electronic paper.
  • This has the advantage that the method which requires computing capacity of the control device is only performed if the user considers this necessary.
  • the method is automatically executed repeatedly, so that the optical data reproduction can be continuously adapted.
  • an optical reproducing apparatus having a receptacle housing from which electronic paper can be unrolled, and a memory for storing data to be optically reproduced on the electronic paper and a controller for controlling the optical data reproduction on the electronic paper, characterized in that a detection device for detecting dimensions of a The control device for processing the data due to the detected dimensions of the display surface in such a way that the data on the currently available display area are substantially completely displayed, is formed and the display surface for Playback of the processed data drives.
  • the detection device can be designed as a displacement transducer, which measures in a suitable manner the uncovered when unrolling the electronic paper path. This is based on the fact that one of the two dimensions of the electronic paper is typically fixed from the outset, namely that dimension which is limited by an exit gap for the electronic paper of the receiving housing.
  • FIG. 1 shows an optical reproduction apparatus with a receiving housing 1 in which a film of optical paper 2 can be accommodated.
  • a roller 3 shown in dashed lines in Figure 1 is provided, from which the optical paper 2 is unrolled.
  • a control device 4 For driving individual pixels of the electronic paper 2 is a control device 4, which is housed together with a memory, not shown for displayed on the optical paper 2 data on a control board.
  • Figure 1 shows the electronic paper 2 with solid lines in a partially unrolled state, while dashed lines represent a position of the electronic paper 2 in fully unrolled state.
  • a query is made as to whether a user of the optical reproduction device wants to make an adaptation of the data that is to be displayed on the display surface 6 to current dimensions of the display surface 6. This query can be confirmed by means of an input interface 7.
  • the query itself can be displayed on the display surface 6 be, for example, always on the remote edge, based on the receiving housing. 1
  • step S3 it is queried whether the control device 4 should be used to access the transducer 5 to adapt the data to the current display surface 6. If this is not the case, there is the possibility that the user makes his own settings via the input interface 7, on the basis of which, independently of the displacement transducer 5, an adaptation of the data is to be undertaken (S5). Regardless of whether step S4 is performed, processing of the data takes place in a step S5 in such a way that they can be displayed substantially completely on the current display area 6. In the case of text data as constituents of the data as a whole, a character font suitable for the current display area size is selected in this connection. Various available character fonts can for example be stored in the memory.
  • step S5 The result of step S5 is that the original data is converted in such a way that, in principle, it can be displayed substantially completely on the display surface 6.
  • step S6 it is checked whether an alignment of the optical data reproduction on the electronic paper 2 is possibly to be adapted to the currently available display area 6. This means in practice that a 90 ° rotated optical reproduction of the data can be selected if, unlike completely unrolled optical paper 2, the value for the height H is greater than the value for the length L.
  • step S6 the data is reprocessed with the aid of the control device 4, so that the optical data reproduction is now determined in terms of size and orientation.
  • step S7 the actual optical data reproduction then takes place.
