Abstract
The utility model discloses an LED display module, which comprises a circuit board with an LED chip, a reflection cavity and an upper cover, wherein a black film layer is arranged on one side of the circuit board in contact with the reflection cavity; and both the reflection cavity and the upper cover adopt black components. By adopting the LED display module provided by the utility model, the color effect of the display screen formed by the LED display module is remarkably improved, the color of the integral screen is vivid, and the color cast is avoided.
Description
Technical field
The utility model relates to a kind of LED display module.
Background technology
Along with the continuous development of LED technology, LED display more and more is applied in multiple occasions such as indoor, outdoor.LED display is made up of a plurality of modules, generally is made up of the circuit board that has led chip, reflection cavity and cover.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, influences 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: have 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 be 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 improvement significantly to the effect of LED screen, and when the LED lamp did not work, entire 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 a 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 set up into the display screen of certain size jointly.As shown in Figure 2, evenly be provided with the corresponding hole 31 of 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 that are used to install 33 are also stretched out at the cover back side.Reflection cavity 2 is sleeved on the inboard of cover 3, also is provided with the corresponding hole 21 of 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 on the reflection cavity 2 21, so that the reflection conical surface that the back forms the LED lamp is installed.
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, earlier reflection cavity 2 is put into cover 3, and utilize the register pin that stretches out on the cover 33 to insert in the pilot hole that is provided with on the reflection cavities to position, the circuit board that will have LED then is fixed on the back side of reflection cavity 2, and makes the LED lamp be arranged in the conical surface hole of reflection cavity and cover qualification.
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 constitutes is simple, color effect good.
Claims (3)
1. a LED display module comprises the circuit board, reflection cavity and the cover that have led chip, it is characterized in that: 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.
