LEDS are specular, while the sky is diffuse. It is not the same visually, and it would be much easier to detect a lit object with instrumentation.

Let's pretend the OLEDS were off and assume no plastic lens on the OLED. The planar silicon surface itself would be highly reflective.

Finally, OLED arrays are matrixed. The pulsed LED would be a piece of cake to detect with instrumentation. If the OLEDS are not matrixed, then you would have a huge associated wiring harness which would be easy to detect with radar.

For these panels to be useful, you need to maintain stealth against all technologies.

There are techniques to make panels glow that are diffuse. It is the same problem as designed a backlight for a transmissive LCD. One technique is to use phosphorescent materials that you excite with UV. They could use UV LEDs. This gets back to the use of composites, which could trap the phosphorescent material in the resin.
