Both LED and DLP (liquid crystal Mosaic screen) can be used indoors, but is it LED or DLP? Today Xiaobian and you talk about the advantages and disadvantages of LED and DLP.

The advantages of DLP are small pixels and high definition, but the disadvantages are splintered seams. At present, the small splintered seams can reach 0.88mm. The rear-projection type and plasma display screen are suitable for close viewing.

The advantages of the indoor full-color LED display are high brightness, no split-seam, the disadvantage is that the pixel particles are thicker and the definition is lower. At present, the economical models of commercialized indoor full-color LED screens are P5 and P6, and other models include P3 and P4. When we buy indoor full-color LED display, we can consider the following aspects.

I. LED tube core

As with the outdoor full-color LED display, it is generally recommended that the LED of the indoor full-color LED display adopts the Mulinsen package LED, and the tube core of Japan's Nichia and America's CREE is recommended for high-grade products.

Second, packaging form

Table paste package 3528, 2121, 1010 has the advantages of large view Angle, good luminescence consistency, easy to automatic welding processing, is the mainstream of full-color LED display products.

Three, density

Because the indoor full-color LED chip heat, control circuit density is high, so now commercial full-color LED display point density can not be done very high. At present, P3, P4, P5 and P6 are widely used in the market, which are relatively economical and mainly mainstream products in the middle and low end market.

4. Driving mode

The indoor full-color LED display is driven by constant current and adopts dynamic scanning mode (mainly 1/4, 1/8, 1/16 and other scanning modes).

5. Refresh frequency

Increase the refresh frequency, no flicker and trailing when the camera is shooting.
