Nikon N75 and Nikon F100 has the LEDs in the viewfinder and on a screen.
But you still couldn’t see the numerals next to the LEDs in poor light. So the camera engineers put the LEDs behind the numbers and lit the numerals themselves. I find LED numerals excellent except in extremely brilliant out-door shooting conditions then these LEDs tend to be difficult to see. In such conditions needles are better but if I had to choose one or the other system for all shooting, I’d go LED.
Why limit LEDs to little dots or small individual numerals? Why not form whole numerals or letters out of them? And so the Canon A-1 and Fujica AZ-1 were born with extremely bright digital LED numerals which, unfortunately drained even the camera’s small E-volt button batteries too quickly.
What do do? Just as LED digital wristwatches have been replaced by liquid crystal display (LCD) timepieces, so the camera engineers have provided low battery drain LCD information panels for camera finders. Sometimes there’s even a second LCD panel atop the camera body to handle the overflow of information not needed for immediate picture taking: proper film loading, ISO film speed setting, battery condition, frame number, length of film, type of program exposure.
Everyone satisfied? Of course not. Unlike LEDs, LCDs do not emit light; they’re mirrors that can only reflect light or panels that can be transilluminated by a light source. You couldn’t see the LCD finder information in low light. So the engineers often put LEDs or small bulbs in front or behind the LCDs to light up when needed. And, thanks to the new camera designs with built-in winders powered by big AAA or AA batteries which energize all camera functions, there’s enough electrical juice for viewfinder low light illuminators.
Now behold our finders! The LCD and LED variations in information and types of display seem unending. They range from the fairly simple black on-white shutter speed and aperture plus manual metering (as on the Nikon F3) to multi-colored mind blowers like the panel in the Richo XR-M. If you don’t like numerals and yearn for the good old days of scales and meter needles, presto, LCD panels can duplicate the effect of a scale and indicator. Want to make spot meter readings and average them? Some SLR scales show at just what light level the multi-spot meterings were made.

Canon T70 and T90Nope! It has a strip of LED not the type of LED which actually forms the number.
So far only the Canon A1, The Fujica ST901 and the Contax RTS II have it.
No Nikon has LED digital display. The F2SB and F2AS have + 0 - LED. The FM's are similar but not digital. The F5 or even as old as the F3 has digital display but LCD and not LED.
Please be fair to us, as your title and first post say differently, there is no such restriction to backlit stencils only.but I dont know where the 7 segmen t led requirement came from as that was never part of my inquiry. Im only asking if anybody knows of cameras that have the shutter speed numbers backlit with led instead of just a led light next to the number. I want the actual number to light up with LED light. So just have the stencil backlit with LED is what Im trying to say.
Please be fair to us, as your title and first post say differently, there is no such restriction to backlit stencils only.
You might have not thought of 7segments LEDs as I did not think of backlighting at first.
I just got a textbook from 1983 at hand and it shows in detail a dozen displays. None of it has LED lit stencils. Only swinging needles, open LEDs and 7segment LEDs.
