Description
Technical Field
The utility model relates to the field of electronic technology, it is specific that digital display device based on LED distributes the paster.
Background
In the prior art, most electronic products display simpler numbers and characters through nixie tubes, and the semi-finished nixie tube module shown in fig. 1 is usually purchased and welded on a PCB. The nixie tube module is single in shape, mostly square, fixed and single in volume size and display content, limits the appearance of an electronic product and the ductility of structural design, and increases the design cost of the product to a certain extent.
SUMMERY OF THE UTILITY MODEL
In order to make up for the above-mentioned not enough of prior art, the utility model provides a digital display device based on LED distributes paster, its technical scheme as follows.
Digital display device based on LED distributes paster includes:
a PCB board on which a driving circuit is configured;
the lamp frame support is detachably arranged on the front surface of the PCB, and the bottom surface of the lamp frame support is in contact fit with the surface of the PCB; the lamp frame support is also provided with a plurality of independent hollow parts which are vertically communicated with the PCB, the PCB is provided with a plurality of LED patches which are respectively positioned in the hollow parts, and the LED patches are controlled by a driving circuit;
the display panel is attached to the top surface of the lamp frame support to shield the hollow part, a plurality of image-text units which are matched with the hollow part one by one are arranged on the display panel, and the image-text units are respectively positioned in the light-transmitting areas in the opening range of the hollow part.
Compared with the prior art, the beneficial effects of the utility model reside in that:
(1) the LED patches are divided into mutually independent light sources by the hollow part of the lamp frame support, and are respectively transmitted by corresponding image-text units on the display panel under the control of the driving circuit so as to be combined and displayed as expected patterns and characters on the display panel;
(2) the height of the lamp frame bracket can be designed as required, and more operation space is reserved for structural design;
(3) compared with a nixie tube module in the prior art, the modularized manufacturing cost is reduced, the LED patches are directly mounted on the PCB according to design requirements, subsequent welding procedures are reduced, the cost is reduced, and the quality is improved.
The present invention will be further described with reference to the drawings and the detailed description.
