Described Multifunctional demonstration two panels TD62M8600F drives the anode of 16 layers, 512 pins of corresponding 32 MBI5026CP of 256 LED negative electrodes, 512 pins of every one deck absorb cathode current, form the display of one deck, switchable layer between 16 layers, forms the multi-functional broadcasting instrument of stereo display.
As preferably, adopt 4 line-16 line Inverse code output code translator 74HC154, the input being used for connecting TD62M8600F chip realizes switching between layers.
The utility model adopt spread over a whole area from one point, by face to the design philosophy of body to carry out design and verification.It is capable that the manufacture craft of described Multifunctional demonstration first can carry out being welded into a LED 16 dual base color LED, then test, test by after carry out next step again, 16 row LED are carried out welding to form LED face, test again, welded 16 layers of LED face and test completely carrys out into the cubical welding of LED by rear.
The beneficial effects of the utility model:
(1) the utility model adopts the dual base color LED cube display system of 16 × 16 × 16, and can show maximum three kinds of colors, display effect is elegant in appearance.
(2) powerful, by being shown in by figure after model delivery on the dual base color LED cube display module of 16 × 16 × 16, the advantage of the incomparable dynamic three-dimensional display of common display module can be had.
(3) workable, adopt touch-screen as man-machine interaction approach, by touch-screen to user want show model delivery and show in real time, this does not have in LED display model in the past.
(4) the utility model can use infrared remote control mode to carry out the selection of model, only can need be shown by reading model by the mode of infrared remote control when needed; Adopt and seal in and the data mode gone out, dramatically saves on taking of I/O, realize making full use of cpu resource to greatest extent; Employing extends out pin-saving chip, by the code storage of each model on storage chip, reduces CPU EMS memory occupation.When needing to add new model, only need download data in storage chip, or preserve after using the self-defined figure of touch-screen.
