PHOTODIODE (OPD)
TFT MATRIX
The photodiode array
absorbs light photons and
converts them into electric
charges.
Electric charges form an
image on a monitor.
ADVANTAGES OF
A FLEXIBLE X-RAY DETECTOR :
❖ High sensitivity, radiation dose is
3 times lower
❖ Device dimensions and weight
are 2 times less (lightness, mobility)
❖ Flexibility and impact resistance
❖ High performance
❖ Panoramic shot with curved
form factor
❖ Digital color image

OPERATION:
An optical signal (laser beam) is reflected by a mirror array (topology drawing of FLEX ID optical tag), then captured by a camera (at a
short distance) or a detector (at a long distance). The received data is converted into a binary code, impossible to counterfeit. Public part
of information can be read with a regular cell phone.
TENFLECS is the only factory in Russia and Europe capable of providing the necessary high optical resolution for the topology design and
smart FLEX ID tag manufacture.

SMART DIMMING FILM (SMART WINDOW)
- A thin and flexible film. Dimming level depends on the applied voltage.
- In the initial state, at zero voltage on the LC cell, light is maximally absorbed.
- When the voltage is turned on, the film goes into a state in which all dye molecules are oriented vertically, and the
incident light passes freely.
TECHNICAL SPEC:
Thickness ~100 µm
No blue/magenta tone and no hazy effect
Fast transition from transparent to opaque or intermediate state
Continuous dimming tuning is possible
Different spectrum and deep light modulation are possible due
to the variation of LC mixture
For LC cells a regular tech. process is applied
Bending radius of dimming films is ~ 100 mm
LC cells retain their integrity and functionality when bent
Dimming modes (light transmission):
• Light – 50%
• Dark – 10%
PILOT SAMPLE
To control dimming modes, a film prototype was made with an electric control unit: input USB 5V
and output 15V bipolar signal to control GH LC cells.
