(1) broad angle of view Not only the outdoors entire color pastes the piece type SMD display monitor to have 110 degree broad angles of view in the horizontal direction, also has 110 degree broad angle of view in the vertical direction, this has the superiority specially in some using the place.

(2) distribution of light is good Red, green, blue ellipse LED in the different angle three kind of brightness's match uniformities is a difficulty very high target, but entire color SMD, because the design structure is the method of three-in-one structure, red, green, blue three chips all in a support bowl cup, therefore in the different angle red, green, the blue three kind of brightness's match uniformity is highly consistent,LED Spot Light Manufacturer thus causes the outdoors entire color to paste the piece type SMD display monitor to send the uniformity in random angle brightness to be very good, achieves the better color lifelike effect.

The following chart 1 and Figure 2 respectively pastes the piece type SMD distribution of light diagram of curves and the outdoors entire color ellipse LED distribution of light diagram of curves be the outdoors entire color. May see through the comparison, the SMD distribution of light uniformity has the obvious superiority compared to ellipse LED.

(3) mixes the light to be good Because the design structure is a method of three-in-one, three chips are away from are very near, mixes the light in the identical support bowl cup, but is not three separation ellipse LED, therefore red, green, mixes the light effect well blue in-line ellipse LED screen, especially suits in the short distance onlooking.

(4) high contrast gradient As a result of the method of three-in-one design structure, the entire color SMD size is small, therefore the illumination area is small,LED Flood Light Manufacturer the black area was big, enhanced the LED display monitor's contrast gradient.
(5) automated production Pastes piece type SMD to be able to use the completely automatic to paste the piece machine to carry on the automation to paste the piece, the production efficiency is high. The entire color pastes the piece type SMD display monitor module the line design to be able to realize the lamp board and the actuation board two-in-one, reduced the cost, enhanced the reliability, has promoted the production efficiency. The automation pastes the piece production also to be able to enhance SMD on the line board vertical precision, has overcome in-line type ellipse LED on the line board the vertical precision question, thus guarantees the better optics effect.

Third, the outdoors entire color pastes piece type SMD the main parameter

(1) brightness At present the outdoors entire color pastes piece type SMD the brightness to be able to satisfy spacing 8mm to paste the piece type SMD display monitor's brightness demand to the 16mm outdoors entire color. And green brightness can achieve 1200mcd to 1600mcd,LED Ceiling Light Manufacturer the entire screen brightness can be higher than 5000nits. In order to guarantee the entire screen brightness the uniformity, each kind of color's luminance range should below 1:1.3, and red, green, the blue three kind of color's mean brightness proportion approximately is 3:6:1.

(2) wave length Red, green, the blue three kind of color's wavelength range should not extend in 5nm, and each kind of color's wave length distribution should assume the normal distribution.

(3) weaken The outdoors entire color pastes piece type SMD, because brightness reason use electric current is relatively high, as a result in the outdoors use, to achieve the smallest weaken, therefore to requests and so on chip size, radiation design, waterproofing, anti-ultraviolet ray is high.

At the same time, red, green, the blue three kind of color brightness decay must have the uniformity, then guarantees the SMD display monitor after the work long time, not only brightness drops is small, moreover brightness and the color uniformity maintain good. The quality outstanding outdoors entire color pastes piece type SMD to be able to guarantee generally works for 3000 hours later red, green, the blue weaken average is smaller than 5%, and red, green, the blue weaken is lower than +10% to the divergence.
