FIELD: physics, computer engineering. ^ SUBSTANCE: invention is related to automatics and computer engineering, namely, to devices for information indication on matrix screen, and may be used in devices of visual indication with matrix screens, which demonstrate varying information. Screen module of visual indication comprises multiple indication cells (IC), which are arranged in certain order, at that every IC generates single pixel (or segment) of image with required gradation of required colour depending on supplied data of image; - multiple facilities for control of brightness and colour (BCCF) by IC number, at that each BCCF is connected to appropriate IC; - multiple units for data distribution by IC number (UDDIC), every of which is connected to appropriate BCCF and performs function of extraction of signals required for this BCCF from common flow of coming signals; - multiple units for reception of power supply and signals (URSS), which receive power supply and signals coming from outside, and every of which is connected to appropriate functional composite parts of visual indication screen module; at that signals coming from outside represent control signals and image data, i.e. data on address of every pixel; - bearing structure (BS) for fixation of composite parts of visual indication screen module, every IC is structurally combined with the following components related to it: appropriate BCCF, UDDIC and URSS into signle sealed structural unit, which is called "standard indication element" (SIE), which realises function of information reception on gradation of image pixel colour and storage of this information - if required and function of this pixel indication (or segment), at that all these structural units (SIE) are fully identical to each other in all parametres; - every SIE additionally comprises programmable address unit (PAU), which is connected to UDDIC of this SIE, and in which, in process of visual indication screen module installation, previously identified information is introduced about address of this SIE. Indication element of visual indication screen module is also described. ^ EFFECT: unification of visual indication screen module units to simplify its design and provide for possibility of large-scale production of these units. ^ 23 cl, 14 dwg |
