Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.

Embodiment 1

As shown in Figure 1, present embodiment provides a kind of LED display 101, and described LED display 101 comprises a panel or a plurality of panel, and plurality of LED light-emitting 103.

Wherein, described panel is set to grid-shaped PCB panel, and is promptly one-body molded by orthogonal horizontal PCB bar 102 and perpendicular PCB bar 104; For example, can be understood as on the large-scale pcb board of a monoblock, be provided with an array, the component of this array is square emptying aperture; Distance between the two adjacent horizontal PCB bars is 5 centimetres to 500 centimetres; Perhaps, the two adjacent distances of erecting between the PCB bars are 5 centimetres to 500 centimetres; Perhaps, the distance between the two adjacent horizontal PCB bars is 5 centimetres to 500 centimetres, and the distance between the two adjacent perpendicular PCB bars also is 5 centimetres to 500 centimetres.

For example, for each horizontal PCB bar, the spacing of adjacent horizontal PCB bar is identical, and for each perpendicular PCB bar, the spacing of adjacent perpendicular PCB bar is identical.

For example, a range of definition is set, comprise following numerical value: 5,8,9,10,12,15,18,20,23,24,25,30,33,36,40,43,45,49,55,60,64,70,72,75,80,81,82,90,99,111,125,138,149,167,186,200,225,256,268,292,303,337,339,353,369,382,406,433,442,451,460,499,500 or the like, unit is centimetre.For each horizontal PCB bar, the spacing of adjacent horizontal PCB bar is a numerical value unit of the above-mentioned range of definition, for example 8 centimetres; The spacing of perhaps adjacent horizontal PCB bar is arbitrary numerical value unit of the above-mentioned range of definition; For each perpendicular PCB bar, the spacing of adjacent perpendicular PCB bar is a numerical value unit of the above-mentioned range of definition, for example 60 centimetres; The spacing of perhaps adjacent perpendicular PCB bar is arbitrary numerical value unit of the above-mentioned range of definition.

Because the dot spacing of common LED display screen between being generally all is set to P5 to P25, promptly 0.5 centimetre to 2.5 centimetres, therefore, in the saturating abortive haul screen of making, maximum spacing between adjacent horizontal PCB bar or the adjacent perpendicular PCB bar is 2.5 centimetres, be installed in the exterior wall of building, shelter from the part visual field of people in the building easily, make the transparency of LED display 101 can not satisfy the requirement of vision, and, because the spacing between the PCB bar is too small, radiating effect is also good inadequately, is difficult to bear the huge temperature difference and hurricane.

For example, spacing between the adjacent two horizontal PCB bars 102 is set to 5 centimetres, and, distance between the two adjacent perpendicular PCB bars 104 also is 5 centimetres, the space that then has 5 centimetres=25 square centimeters of 5 cm x between the PCB bar, can be when enough satisfying people's vision needs, reduce the energy consumption of LED display 101, and, because the spacing between the PCB bar increases, the dot spacing that then is arranged between the LED luminescence unit 103 on the pcb board also increases, therefore, good heat dissipation effect can be born the bigger temperature difference and hurricane.Need to prove that the spacing of adjacent two horizontal PCB bars, and the spacing of adjacent two perpendicular PCB bars can be the distances between the PCB bar edge, also can be the distances between the PCB bar center; PCB bar center, i.e. the PCB bar of a rectangle or similar rectangle, any point on its center line or the class symmedian; Two center lines of adjacent two PCB bars, parallel or approximate parallel.

And for example, spacing between the adjacent two horizontal PCB bars 102 is set to 500 centimetres, be 5 meters, and, distance between the two adjacent perpendicular PCB bars 104 also is 500 centimetres, the space that then has 500 centimetres=250,000 square centimeters of 500 cm x between the PCB bar, can satisfy the application of extra-large LED display screen 101 in high buildings and large mansions, the installation of this LED display 101, can not hinder people's vision needs fully, and,, can make the energy consumption of LED display 101 drop to minimum because the electronic devices and components of LED display reduce in the unit area.And the radiating effect of described LED display is best, can bear the huge temperature difference and hurricane.
