Abstract
The utility model discloses an LED display module, which comprises a circuit board with LED chips, a reflective cavity and a surface cover, wherein one side of the circuit board, which is in contact with the reflective cavity, is provided with a black film layer, and both the reflective cavity and the surface cover are black components. The color effect of a display screen comprising the LED display module provided by the utility model is remarkably improved, so that the colors of the whole screen are vivid, and chromatic aberration cannot occur.
Description
Technical field
The utility model relates to a kind of LED display module.
Background technology
Along with the development of LED technology, LED display more and more is applied in the multiple occasions such as indoor, outdoor.LED display is comprised of a plurality of modules, generally is comprised of circuit board, reflection cavity and cover with led chip.The LED display module that prior art provides, its reflection cavity adopts white board structure, and there are a plurality of conical reflection cavities in even branch on it, when this module does not work when the LED lamp, because white substrate produces diffuse reflection, makes whole screen burnt hair; When the LED lamp was bright, when black, Huang and red trichromatism colour mixture, the white of emission cavity made mixed light produce deviation, affects color effect.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned problems of the prior art, proposes a kind of improved LED display module.
The LED display module that the utility model proposes comprises: with circuit board, reflection cavity and the cover of led chip, the side that described circuit board contacts with reflection cavity is provided with a black thin film layer, and reflection cavity and cover are the black member.
Described reflection cavity and cover are made by the black plastic material, and can be one-body molded.
Compared with prior art, the LED display module that the utility model proposes has significantly improvement to the effect of LED screen, and when the LED lamp did not work, whole display screen was black, and when the LED lamp was bright, whole screen color was true to nature, color error ratio can not occur.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in detail, wherein:
Fig. 1 is side sectional view of the present utility model;
Fig. 2 is the front schematic view of cover in the utility model;
Fig. 3 is the schematic rear view of emitter in the utility model.
Embodiment
As shown in Figure 1, the LED display module that the utility model proposes comprises circuit board 1, reflection cavity 2 and the cover 3 that stacks gradually suit.Regularly arranged on the circuit board 1 have a led chip.This module adopts cube structure, and a plurality of module spliced are combined into the display screen of certain size.As shown in Figure 2, evenly be provided with hole 31 corresponding to LED lamp many and on the circuit board 1 on the panel of cover 3, stretch out backward around the cover, form surrounding edge 32, at least 2 register pins 33 that are used for installation are also stretched out at the cover back side.Reflection cavity 2 is sleeved on the inboard of cover 3, also is provided with hole 21 corresponding to LED lamp many and on the circuit board 1 on it, and the aperture 22 that cooperates with register pin on the cover 3.Circular port or polygonal hole can be adopted in hole on cover 3 and the reflection cavity 2, and the bore in the hole on the cover 31 should be greater than the bore in the hole 21 on the reflection cavity 2, in order to form the reflection conical surface of LED lamp after installing.
The side that circuit board 1 contacts with reflection cavity 2 in the utility model is provided with a black thin film layer, and reflection cavity and cover 3 are the member of black.
When the LED display module that the utility model proposes is installed, first reflection cavity 2 is put into cover 3, and utilize the register pin 33 that stretches out on the cover to insert in the pilot hole that arranges on the reflection cavities to position, then will be fixed on the circuit board of LED the back side of reflection cavity 2, and make the LED lamp be arranged in the conical surface hole of reflection cavity and cover restriction.
In an embodiment of the present utility model, reflection cavity can adopt the black plastic material one-body molded, also reflection cavity and cover one can be reinstated the black plastic integrated injection molding.
Through evidence, the display screen structure that the LED display module that the utility model proposes consists of is simple, color effect good.
Claims (3)
