MD4 Screen burn-in time without screensaver
How long does a static image need to remain displayed on an MD4-7 screen before image burn-in is noticeable?
Assume worst case. (Worst case being probably full brightness with high contrast graphics??)
What is the recommended time-out for when a screensaver should start? Would just dimming it for the screensaver avoid burn-in? How much should it be dimmed?
The MD4 instruction book (rev 2015-12-02) says:
Burn-in
The IQAN-MD4 TFT display, like other computer screens can have a ghost picture
occur if a static image is left on the display for extended periods of time. For the best
viewing over the life of the product we recommend using the screensaver functionality.
NOTICE
To avoid burn-in, use the screensaver on the display
Standby mode for MD4
Hi everyone,
We want to adding a new feature on MD4 controller. When the system locked function is true, standby mode should be active because of energy-saving.
Best regards.
Freeze of the touch screen on MD4
We are using an MD3 and MD4 as screen on our system.
They print the same info from one CAN BUS
They are on the same system than a generator quite noisy, and when the generator start we loose the touch on the MD4, only the touch.
- The screen still work good
- the Md3 act normal
Did any body experiment the same kind of issue?
I don't have a scope on site I am investigating right now on the issue. I will try to
Power supply the MD4 from an other power source
Isolate the power suply if it doesn't work
I will try to add a capasitor if I have time.
M4 Safe Mode
I have a customer who attempted to move the location of an MD4 and in rewiring has got the wiring wrong! The screen will not now complete its boot up cycle and the diagnostics bus is not available to try to interrogate the machine.
There seems to be a tiny recessed red button alongside one of the screws on the rear of the screen - is this a safe mode button?
Wrong IdTag! Error on MD4
On two separate machines now (with identical systems) we have received customer reports of an issue of the IQAN system stopping functioning during machine operation.
On the MD4, the screen will say STOP System Message: IQAN-Master Wrong IdTag! system
I have been told that power cycling will not fix the issue. The only way to resolve is to unplug the Deutsch connector from the back of the MD4 and then plug it back in.
This is an intermittent issue. The machines can run 100+ hours before the issue repeats.
The customer was advised to check resistance on the ID Tag (resistance was correct) and to check the pins and wiring condition at the MD4 for any anomalies or corrosion (nothing identified).
Do you have any guidance on this issue?
Battery for MD4
I think that inlcuding an internal battery would be interesting in order to maintain RTC values.
Thanks.
fantastic display
MD4 problems when backlight is 70% or above.
If you adjust backlight in the MD4 higher then 70% the screen brightness gets unstable starts vary in brightness up and down.
MD3 and MD4 Operating temperature
