Abstract
The utility model relates to a light emitting diode (LED) display screen. The display screen comprises a substrate and a cover, wherein the cover is arranged on the surface of the substrate and is provided with elliptical holes; the walls of the holes are black; and the visual angle of the elliptical holes of a module are 160 degrees. In the LED display screen, the circular holes of the conventional module are changed into the elliptical holes, so that the habits of watching of human eyes are met; meanwhile, the horizontal visual angle is increased under the condition of not changing the vertical visual angle of the holes on the original cover; the entire display screen which is formed by splicing the modules has an attractive appearance; and when the display screen is electrified to display a pattern, the contrast of a light region and a dark region is improved, and the visual effect is greatly improved.
Description
Technical field
The utility model relates to a kind of LED display.
Background technology
LED display is the comprehensive product of the sub-technology of current collection, computer technology, infotech, photoelectric technology, can fully be used for the multimedia messages issue, and display screen is to be spliced by display panel module.At present, the external member of display panel module mostly is round hole, and the visual angle of perforate is little, have only 140 degree, and the surface color of module and the color of substrate are inconsistent, cause before display screen energising shows easily to make the display screen outward appearance not attractive in appearance, after energising shows, make low, the poor visual effect of dim pattern, resolution on the display screen.At present, still there is not good method to solve this problem.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of good looking appearance, good visual effect, visual angle, the perforate left and right sides is big, pattern resolution is high LED display.
The utility model is achieved in that
A kind of LED display, it comprises substrate, external member, and external member is installed in substrate surface, and perforate is arranged on the external member, and the hole shape on the external member is an elliptical aperture.
The utility model makes traditional module perforate circular hole into elliptical aperture, meets human eye and watches custom; Simultaneously, keeping former external member perforate up and down under the constant situation of visible angle, strengthen visual angle, the left and right sides, be increased to 160 from 140 original degree, increased the display area proportion, bright dark space ratio was by 1: 1.3 to 1.9: 1; Particularly, change module perforate hole wall into the black background color by original white background color, inner substrate changes the black background color into by original white background color, reach close or consistent with the black of exterior substrate, make the entire display screen appearance looks elegant that module spliced is connected into, when the energising display pattern, also improved light and shade district contrast, greatly improved visual effect.
The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the utility model cut-open view.
Fig. 2 is the utility model structural representation.
Embodiment
See Fig. 1, Fig. 2, a kind of LED display, it comprises substrate 1, external member 2, external member is installed in substrate surface, and oval aperture 3 is arranged on the external member.External member perforate hole wall is a black.Described module oval aperture visual angle is 160 degree.The utility model makes traditional module perforate circular hole into elliptical aperture, meets human eye and watches custom; Simultaneously, keeping former external member perforate up and down under the constant situation of visible angle, strengthen visual angle, the left and right sides, be increased to 160 degree from 140 original degree, increased the display area proportion, bright dark space ratio was by 1: 1.3 to 1.9: 1; Particularly, change the substrate of module perforate inside into the black background color by original white background color, reach consistent with the black of exterior substrate, make the entire display screen appearance looks elegant that module spliced is connected into, when the energising display pattern, also improved light and shade district contrast, greatly improved visual effect.
