Abstract

The utility model relates to a light-emitting diode (LED) display screen, in particular to a high-contrast LED display screen. The high-contrast LED display screen comprises at least two face masks, wherein a groove is formed between adjacent face masks. The utility model has the advantages that: a phenomenon of uneven adjacent face masks can be reduced through the groove so as to improve the overall flatness of the LED display screen; moreover, a gap value of the adjacent face masks can be unified through the groove so as to improve the overall gap uniformity of the LED display screen, the display contrast is improved, and a display effect is optimized.

Description

A kind of LED display of high-contrast

Technical field

The utility model relates to LED display, relates in particular to a kind of LED display of high-contrast.

Background technology

LED display (LED panel; LED is exactly light emitting diode; The english abbreviation of light emitting diode; Be called for short LED) be a kind of display device through the control semiconductor light-emitting-diode, lean on the light on and off of semiconductor light-emitting-diode to come character display, be used for the display screen of various information such as display text, figure, image, animation, market, video, video signal.

LED display generally includes face shield, and several face shields are spliced to form a display screen, therefore; When the assembled LED display screen, need splice adjacent face shield, existing face mask structure is after splicing; There is the uneven phenomenon in the high end in adjacent face shield, causes the whole flatness of LED display lower, and the gap of the adjacent face shield phenomenon that exists width to differ; Cause the whole gap homogeneity of LED display lower, finally cause the contrast of display degree to compare the end, influence display effect.

Summary of the invention

In order to solve the problems of the prior art, the utility model provides a kind of LED display of high-contrast.

The utility model provides a kind of LED display of high-contrast, comprises at least two face shields, is provided with groove between the adjacent said face shield,, the width of said groove is 0.3 to 0.7 millimeter.

As the further improvement of the utility model, the width of said groove is 0.4 to 0.6 millimeter.

As the further improvement of the utility model, the width of said groove is 0.5 millimeter.

As the further improvement of the utility model, said face shield is grid and distributes.

As the further improvement of the utility model, said face shield is provided with light hole.

As the further improvement of the utility model, the edge of said face shield is provided with depressed part, and said depressed part is the half the of said groove.

As the further improvement of the utility model, the sidewall of said groove is a skew wall.

As the further improvement of the utility model, the pitch angle of the sidewall of said groove is 100 degree.

As the further improvement of the utility model, said face shield is array distribution.

As the further improvement of the utility model, said face shield is a rectangle.

The beneficial effect of the utility model is: through such scheme; Thereby can weaken the uneven phenomenon in the high end of adjacent face shield through groove and improve the whole flatness of LED display; And the gap width that can unify adjacent face shield through groove; To improve the whole gap homogeneity of LED display, improved the contrast of display degree, optimized display effect.

Description of drawings

Fig. 1 is the perspective view of the LED display of a kind of high-contrast of the utility model;

Fig. 2 is the structural representation of looking up direction of the LED display of the said high-contrast of the utility model.

Embodiment

Below in conjunction with description of drawings and embodiment the utility model is further specified.

Drawing reference numeral among Fig. 1 to Fig. 2 is: face shield 1; Groove 11.

To shown in Figure 2, a kind of LED display of high-contrast comprises at least two face shields 1, is provided with groove 11 between the adjacent said face shield 1 like Fig. 1,, the width of said groove 11 is 0.3 to 0.7 millimeter.

To shown in Figure 2, the width of said groove 11 is 0.4 to 0.6 millimeter like Fig. 1.

To shown in Figure 2, the width of said groove 11 is 0.5 millimeter like Fig. 1.

To shown in Figure 2, said face shield 1 is grid and distributes like Fig. 1.

To shown in Figure 2, said face shield 1 is provided with light hole like Fig. 1.

To shown in Figure 2, the edge of said face shield 1 is provided with depressed part like Fig. 1, and said depressed part is the half the of said groove 11.

To shown in Figure 2, the sidewall of said groove 11 is a skew wall like Fig. 1.

To shown in Figure 2, the pitch angle of the sidewall of said groove 11 is 100 degree like Fig. 1.

To shown in Figure 2, said face shield 1 is array distribution like Fig. 1.

To shown in Figure 2, said face shield 1 is a rectangle like Fig. 1.

The LED display of a kind of high-contrast that the utility model provides; Thereby can weaken the uneven phenomenon in the 1 high end of adjacent face shield through groove 11 and improve the whole flatness of LED display; And the gap width that can unify adjacent face shield 1 through groove 11; To improve the whole gap homogeneity of LED display, improved the contrast of display degree, optimized display effect.

Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
