Abstract
The utility model concerns a cover plate of LED display panel. The cover plate is provided with a main body, and a plurality of through holes formed on the main body in matrix array for passing light from LED lamp. At least partial inner walls of the through holes close to surface of the main body have outward extending inclined surface, so as to provide larger visual angle for the LED display panel.
Description
[technical field]
The utility model relates to a kind of SMD paster mask plate, particularly a kind of LED screen case mask plate.
[background technology]
The range of application of large LED display screen (hereinafter to be referred as LED screen) more and more widely, it can be applicable to various occasions such as indoor outer advertisement, physical culture, traffic, performance, exhibition, lease, rally.At present, the LED display of SMD (surface mount) paster has become the main product of the medium and high level of indoor LED screen with advantages such as its high resolving power, high brightness.SMD paster LED screen generally is used for indoor or semi-outdoor, because comparatively speaking, indoor viewing distance is less, therefore, mask plate to SMD paster LED screen requires rather strict, need it to have and make the LED screen possess bigger visible angle, and prevent that the light between the different LED from disturbing, and prevent that houselights or sunshine from shielding the reflection of body at LED.
At present, the mask plate of existing SMD paster LED screen mostly just is provided with some rectangular openings on body, and four inwalls of each rectangular opening all are straight wall, LED is installed in each rectangular opening, offer through hole on this body, be arranged in the through hole, mask plate can be fixed on the PCB by screw.Yet the inwall of the through hole of above-mentioned mask plate is straight wall, and it can have influence on the visible angle of LED screen, and the light between the different LED can disturb, and houselights or sunshine can reflect on the screen body, cause glare phenomenon.On the other hand and since on the above-mentioned mask plate for screw locking be through hole, the head of screw can expose, and influence outward appearance that whole LED shields and the divergent views of blocking LED.
[utility model content]
Technical problem to be solved in the utility model is to provide the big LED of a kind of visible angle to shield the case mask plate.
The utility model the technical matters that will further solve be to provide a kind of LED screen case mask plate, it can prevent that the light between the different LED from disturbing, and prevents the reflection at LED screen body of houselights or sunshine.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of LED screen case mask plate is provided, it has body, on described body, offer some through holes that are arranged, are used for supplying LED lamp printing opacity, near on the inwall of body surface, have outward extending dip plane to the small part inwall in each through hole.
Through hole of the present utility model is rectangular.
The left inwall of through hole of the present utility model, right inwall and following inwall are provided with the dip plane.
Also be provided with the dip plane on the last inwall of through hole of the present utility model.
The left inwall of through hole of the present utility model, right inwall and last inwall are provided with the dip plane.
Also be provided with the dip plane on the following inwall of through hole of the present utility model.
The surface etching of body of the present utility model has mute tarry matter sand streak or is sprayed with mute tarry matter sand dirty oil.
Offer the counterbore that wears for screw on the body of the present utility model.
Counterbore of the present utility model is positioned at the intersection of four through holes on the body.
Compared with prior art, because the inwall of through hole of the present utility model is provided with the dip plane, make LED display that bigger visible angle be arranged.In addition, also be provided with mute tarry matter sand streak or mute tarry matter sand dirty oil on the mask plate of the present utility model, can prevent that the light between the different LED from disturbing, and prevent houselights or the reflection of sunshine on the screen body, prevent glare phenomenon.
[description of drawings]
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is the front elevational schematic of the utility model one preferred embodiment.
Fig. 2 is the cross-sectional schematic along A-A line among Fig. 1.
Fig. 3 is the cross-sectional schematic along B-B line among Fig. 1.
Fig. 4 is the enlarged drawing of I part among Fig. 1.
Fig. 5 is the enlarged drawing of II part among Fig. 2.
Fig. 6 is the enlarged drawing of III part among Fig. 3.
Fig. 7 is the cross-sectional schematic along C-C line among Fig. 1.
[embodiment]
Seeing also Fig. 1 to Fig. 7, is a preferred embodiment of the present utility model, and this LED screen case mask plate has body 1, offers some rectangular openings 2 that are arranged on body 1, for LED (not shown) printing opacity.All be provided with outward extending dip plane 22 on four inwalls in the upper and lower, left and right of each rectangular opening 2, these dip plane 22 are positioned near on the inwall on body 1 surface.The SMD paster LED can be positioned in the above-mentioned rectangular opening 2 by rule, thereby can protect LED to avoid foreign object damage, prolongs the serviceable life of LED.Because the inwall of above-mentioned rectangular opening 2 has dip plane 22, it can make the LED screen have bigger visible angle.Certainly,, also can on the part inwall of above-mentioned rectangular opening 2, dip plane 22 be set according to different occasions, for example: left inwall, right inwall and on dip plane 22 is set on the inwall, perhaps at left inwall, right inwall and on the inwall dip plane 22 is set down.In addition, also can offer the through hole of other shape on the body 1 of the present utility model, near on the inwall on body 1 surface, have outward extending dip plane to the small part inwall in each through hole.
Further improvement as above-mentioned embodiment, can like this, can prevent that the light between the different LED from disturbing at mute tarry matter sand streak (not shown) of above-mentioned body 1 surface etching or the mute tarry matter sand dirty oil of spray, and houselights or the reflection of sunshine on the screen body, prevent glare phenomenon.
Above-mentioned LED screen case mask plate can be fixed on the PCB (not shown) by the screw (not shown), it is more reliable on the PCB, smooth that mask plate is fixed on, further impel the LED screen to have bigger visible angle, in the present embodiment, intersection in four rectangular openings 2 of body 1 offers a plurality of counterbores 3, wears for screw.Owing to adopt the design of counterbore 3, the head of screw can be sunken in the counterbore 3 and can not expose, thereby reaches effect elegant in appearance, and can not block the divergent views of LED.
