Abstract
The utility model discloses a flat type LED display screen which comprises a heat radiating body. A lower LED circuit board is arranged on the bottom of a heat radiating body mounting groove, a plurality of convex edges are formed on the lower LED circuit board, LED luminous bodies are arranged on the convex edges, an upper LED circuit board is arranged on the top portion of the heat radiating body mounting groove, a plurality of LED luminous bodies arranged in rows are arranged on the upper LED circuit board, long through holes allowing the convex edges of the lower LED circuit board to pass through are formed between the adjacent rows on the upper LED circuit board respectively, and a plurality of heat radiating through holes are formed in the side wall of the heat radiating body. According to the flat type LED display screen, luminance compensation can be carried out, and therefore the problem that the luminance of part of the LED display screen is not enough is solved, and the display effect is improved.
Description
Technical field
The utility model relates to the LED display field, is specially a kind of plate type LED display screen.
Background technology
LED screen is a kind ofly to arrange in order and the novel imaging electronics made with light emitting diode.Because the characteristics such as its brightness is high, visible angle is wide, the life-span is long just are being widely used in the demonstration field.Prior art LED display, its display brightness are determined by the LED luminous body array, are prone to the weak problem of local indivedual local brightness, affect whole display effect.
The utility model content
The purpose of this utility model provides a kind of plate type LED display screen, to solve the problem a little less than the prior art LED display is prone to local luminance.
In order to achieve the above object, the technical scheme that adopts of the utility model is:
A kind of plate type LED display screen, comprise that the top has the radiator of mounting groove, the radiator bottom is shaped to corrugated radiating surface, it is characterized in that: radiator mounting groove bottom land is provided with lower led circuit plate, form the LED luminophor that is respectively arranged with on multiple tracks fin and each fin along the fin word order on the lower led circuit plate, radiator mounting groove top is provided with the led circuit plate, the LED luminophor that a plurality of ranks are arranged is installed on the upper led circuit plate, form respectively the long through-hole that passes through for lower led circuit plate fin on the upper led circuit plate between the adjacent columns, and the LED luminophor on the lower led circuit plate fin flushes with LED luminophor on the upper led circuit plate, also is provided with the heat radiation through hole that a plurality of connection radiators are outer and mounting groove is interior on the described radiator sidewall.
Described a kind of plate type LED display screen is characterized in that: be provided with insulated thermal insulating layer between the described upper and lower led circuit plate.
The utility model is comprised of two-layer led circuit plate, its upper led circuit plate at the middle and upper levels is main display board, the lower led circuit plate of lower floor is auxiliary display board, and auxiliary display panel used in carrying out luminance compensation, main and auxiliary display screen is all worked under the control of LED display control circuit.The utility model can carry out luminance compensation, thereby has solved the inadequate problem of LED display local luminance, has improved display effect.
Description of drawings
Fig. 1 is the utility model structural representation.
