New p2.5 p3 and p4 made to test in duel configuration all ic chips match on all the panels 5166p icn 2012 icn now icn 2038 by chipone marked on panels t1 t2 t3 t4 sop 16 pin to replace sop 8 pin MOSFETs 4096 solve bleeding issues

ICN2038

LED display driver IC

ICN2038

Functional characteristics

1,16 channel current output channel

2, the output current setting range:

    0.5 ~ 45mA × 16@VDD=5V constant current output

3, the current accuracy

    Current accuracy between channels: <± 1.5%

    Current accuracy between chips: <± 2.5%

4, fast output current response (minimum): 40ns @ VDD = 5V

5, I / O Schmitt Trigger Trigger input

6, double latch, 1.5 times the refresh rate

7, with blanking, remove the cross

8, excellent low ash effect, no pitting, no odd even vertical stripes

9, excellent anti-interference ability

Hi you lovely people got some news 

Don't mix panels make sure they have 2012 in one set 

Or 7268 or sm5166p image above and all led lamps are smd2121

The reason the bleeding on the p4 is stm32 discovery

Don't like certain panel chips and need sm5166p

I got a seller giving me a set for a sample testing

https://m.aliexpress.com/store/1186165?trace=store2mobilestoreNew#/ this manufacturer will make these panels if 

You want them to be made he said 1,000 PCs 

New p2.5 and p3 are now been remade and capacitors have been removed as not needed

 

P3  47.00 £ + shipping

P 2.5 62.00 £ + shipping  and below p4  42.69 £ + shipping

 

With the required sm5166p

As I forgot my very first p3 set are sm5166p and they have no problems what so ever so u need p3 p4 p5 just the same

So I'm going to try p2.5/p3 /p4 with the same ic from the same suppliers

Len LI a old Chinese friend of mine said that different chips on

The panels can cause  conflict making ghosting worse and 

Damaging the panel all together if not paired the same to help

The stm output protection

Use  diode a cross r1 r2 g1 g2 b1 b2 outputs to inputs of panels only but need a PDF circuit designed as add on to current shield

Diodes are use for sending current one way and also converting AC current to DC 

Some sellers on Ali express are putting panel in images that 

Look like the top dog b@lllocks but are deceiving customer s

To make the sales and should never bs a Englishmen as I worked with them for 7 years

And know how they tick

Thanks paul

The new P 2.5 testing seems fine and looks good so far

New p4 works 100 percent with sm5166p
