psmmacker Posted January 4, 2017 Share Posted January 4, 2017 These are the best panels to use as i got no issues of colour bleeding ps ask seller to send you pictures always look for T1. To T4 chips new panels and my new p 2.5 panel design These also are SM5166p Old panels.examples p4 note no (2121) below Not Chipone ICN 2012 either cheaper chip drivers MP7258B Sm2121 chip one on p3 look like i got to change the chips on the p4 and reflow with a heatgun These are the new chips used on p3 p4.p5 panals and gives better refresh rates also used in 32/1 panels ICN2012 chip built-in 138 decoder, fast and accurate data transmission light lamp beads. Q3 products for the powerful giant circuit design saves a lot of external space, more conducive to improving product stability and overall performance. From the protection circuit, lamp safety to eliminate ghosting, the phenomenon of caterpillars, and then to decode the decoder efficient transmission of data, a small chip integrates so many functions for the powerful giant color Q3 product reliability and display Provides a powerful guarantee. At the same time, high-performance constant-current configuration of the industry-leading double latch, high brush driving record set IC-- north ICN2038, and ICN2012 together to create a superior quality of Q3. At present, ICN2012 as standard should be used in the strong Giant Q2, Q3, Q4 and other indoor high-end display applications; and with the application of the promotion, there will be more products on the use of LED display "beauty camera" - Set the North ICN2012 In the vast LED display "as" sector, low-power, rich forms of communication LED display has quickly occupied the market, has been widely used. The face of the LED display industry at different levels of market demand, set the north to a full range of high school low-end product distribution, firmly occupy the market share of the throne. On the set of the north of the current product planning point of view, the basic section of the main ICN2025, while ensuring the stability can also provide the ultimate cost. ICN2012 is a highly integrated chip that can replace the four 4953. ICN2012 is a highly integrated chip, which can replace the four-chip 4948. The ICN2012 is a highly integrated chip, which can replace four 4953 8 pin mosfets in all RGB panel made before 2014The ghost is a system at different times, respectively drive scan line, in shutdown on 1 Line 1 and drive the next line, 1 on line circuit that remain in the power of the release, only by the LED in the form of the release of the dim bright. The Caterpillar is a phenomenon is the scanning screen. The LED lights on the quality of the leakage or there is a short circuit in the light pipe is punctured so that the lamp of the list of additional light is always is highlighted. General increases the resistance method allows only two phenomena, and cannot be completely resolved, because the smaller distance between points of the Panel body would have on the per unit area more lamp, magnified the LED display picture quality.

Not unless a pindmd firmware was reprogrammed to drive theses panals at half scan But 32/1 the aliexpress sellers have said theses may not work on our controller Example mosfet 8 pin below Link to comment Share on other sites More sharing options...
