Whose key points of technical schedule is that it comprises a shell of the digital display screen, a driver IC for LED and a logic circuit display plane of LED, characterized in that the said LED driver IC is tied to the logic circuit display plane of LED to form a module circuit display plane of LED provided in the shell of the digital display screen. It applies for electric devices such as VCD, DVD and so on.
Description
Technical field
The utility model relates to a kind of LED digital display device.
Background technology
Existing LED digital display device comprises digital display screen shell, LED logical circuit display board, LED drive IC and wiring control panel.Wherein, LED logical circuit display board is contained in the digital display screen shell, and the LED drive IC is welded on the wiring control panel, and the circuit of the LED drive IC on the pin of a plurality of LED that comprised on the LED logical circuit display board and the wiring control panel welds mutually.Though such LED digital display device can be realized the function that shows, there is following deficiency: 1, low with a plurality of line work efficient of artificial welding, especially be easy to generate defectives such as rosin joint, dry joint, not prison welding, make product quality be difficult to guarantee.If adopt weldering automatically, then the equipment purchasing expense is very expensive.2, device is compact inadequately, and volume is bigger, so it is big to take up room.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of LED logical circuit display board and LED drive IC the combination after volume-diminished in the digital display screen shell of can packing into, thereby conserve space, and the LED digital display device of simplifying working process, reduce cost, ensuring the quality of products.
Another purpose of the present utility model is except that realizing above-mentioned purpose, can also make LED drive IC perfect heat-dissipating, thereby can guarantee the LED digital display device of long-time operate as normal.
More than first purpose adopt following technical scheme promptly can realize: the technical program is the same with prior art, comprise digital display screen shell, LED drive IC and LED logical circuit display board, its improvement is that said LED drive IC is bundled on the LED logical circuit display board and forms a led module logical circuit display board that can be contained in the LED digital display screen shell.
Second purpose realizes it being on the basis of technique scheme, the position of preparing binding LED drive IC on said LED logical circuit display board is processed with at least one through hole, be fixed with heat conduction copper layer on the hole wall of this through hole, be closely fitted with a conducting copper plate on the logical circuit display board of the following position of through hole.
In order further to increase LED drive IC radiating effect in the course of the work, ground wire that can said LED drive IC is provided with at least one thick lead-in wire and is connected with the side copper material of LED logical circuit display board.
The beneficial effects of the utility model are:
1. for first kind of technical scheme, the LED drive IC is bundled on the LED logical circuit display board and forms the led module logical circuit display board that to adorn in the LED digital display screen shell, saved original wiring control panel, thereby volume and occupation space have been dwindled greatly, reduce cost, improved production efficiency, particularly simplified operation, the quality of connection line is improved greatly, overcome the defective of original rosin joint, dry joint and not prison welding.
2. for second kind of technical scheme, except having above advantage, LED drive IC perfect heat-dissipating can also be made, thereby the long-time operate as normal of the digital display module of LED can be guaranteed.
In order to make the utility model more clear, the utility model is described in further detail below by drawings and Examples.
