Abstract: In terms of the two display
effects of surface mount and sub-surface mount, the effect of surface mount will be closer to the effect of flat-screen TV, while the color of sub-surface mount will be relatively worse, but the price will be much cheaper. Years ago, there were only module full-color and surface-mounted full-color, and the price of surface-mounted full-color was surprisingly high. The full-color effect of the module was not good and the maintenance cost was high. The surface-mounted touch display was used as a light-emitting electronic device , The processing technology of its lamp beads has become more and more mature with the development of science and technology. After experiencing the traditional lamp insertion and dot matrix technology, the surface mount technology is now the general trend. Surface mount refers to the direct soldering of the packaged luminous tube to the circuit board. It has good heat dissipation and color uniformity. Because it is directly soldered to the circuit board, it can be directly maintained on the front of the display, greatly reducing The maintenance cost and difficulty are reduced. The sub-surface mount is to encapsulate the light-emitting tube into a rectangular shape, and then put the red, green and blue tubes together to form a pixel and group them into a module. The professional term is also called plug-in real pixels. Sub-surface mounting is a way of LED dot matrix composition in the LED dark display industry. It is different from surface mounting. Surface mounting is a patch technology, but sub-surface mounting inserts the lamp pin into the hole of the PCB, but it can Achieve the effect of surface mount lamp. Surface mount refers to patch technology, while sub-surface mount refers to the LED inserting the lamp pin into the PCB hole, but it can show the effect of the surface mount lamp. In terms of the two display effects of surface mount and sub-surface mount, the effect of surface mount will be closer to the effect of flat-screen TV, while the color of sub-surface mount will be relatively worse, but the price will be much cheaper. There are only module full-color and surface-mounted full-color, and the price of surface-mounted full-color is surprisingly high. The module's full-color effect is not good and the maintenance cost is very high. Therefore, the full-color of sub-surface mount should be in the market. produce. Comparison of sub-surface-mount and surface-mount LED electronic displays: Sub-surface-mount advantages: there are some differences in the display color consistency, viewing angle and other primary indicators and surface-mount solutions, but the cost is lower, the display effect is very good, and the resolution can be theoretically possible Achieve more than 17,200. Disadvantages: The processing is still more complicated, and the antistatic requirements are high. Surface mount advantages: high color consistency, viewing angle and other important indicators, especially the color mixing effect of three-in-one surface mount is very good. Disadvantages: the processing technology is troublesome and the cost is high.
