    摘要： A display device has a plurality of display units (D.sub.1, D.sub.2 . . . D.sub.n), each display unit consisting of a number of multiplex-operated display sections, each of which has a plurality of display elements which can be simultaneously but independently switched and each of which has a respective display driver (for example, T.sub.1), and a circuit arrangement for controlling the display device. The circuit arrangement includes a memory (M) in which the information to be output via the display device is stored, a microcontroller (MC) which has at least one synchronous serial interface (2) and a DMA controller (3) for transferring data intended for each time the same display section of the display units (D.sub.1, D.sub.2 . . . D.sub.n) from the memory to the interface, a shift register arrangement (S.sub.1, S.sub.2 . . . S.sub.n) which is connected to the serial interface (2) and which has a parallel output, and storage members (L.sub.1, L.sub.2 . . . L.sub.n) which are connected to the parallel output of the shift register arrangement for periodically taking up the contents of the shift register arrangement and for controlling the display drivers (T.sub.1, T.sub.2 . . . T.sub.n).

    摘要翻译： 显示装置具有多个显示单元（D1，D2 ... Dn），每个显示单元由多个多路复用操作的显示部分组成，每个显示单元具有可同时但独立地切换的多个显示元件， 每个具有各自的显示驱动器（例如，T1）以及用于控制显示装置的电路装置。 该电路装置包括存储有通过显示装置输出的信息的存储器（M），具有至少一个同步串行接口（2）的微控制器（MC）和用于传送数据的DMA控制器（3） 每次从存储器到接口的显示单元（D1，D2 ... Dn）的相同显示部分，连接到串行接口（2）的移位寄存器装置（S1，S2 ... Sn） 并且具有并行输出，以及存储部件（L1，L2 ... Ln），其连接到移位寄存器装置的并行输出端，用于周期性地占用移位寄存器装置的内容并用于控制显示驱动器（T1 ，T2 ... Tn）。
