 So we're here at the SID display week and and hi hey hello how are you so who are you hey my name is Kio and I'm a technology consultant with Illumi Tech it's a new company and what are we looking at here so this is a new fingerprint sensor made by BOE and I say it's based on TFT technology so this is I think the first time a big company showing this kind of fingerprint sensor first time and what is what is special about this maybe you can try to ask yes so they're saying it's based on TFT so some companies have shown optical fingerprint sensor so this is optical fingerprint sensor so some companies are synaptics have shown something that you can use as well as an optical fingerprint sensor but the difference is that they're using their TFT the expertise in making displays now they're using the same kind of expertise to make a sensor so because the TFT is used in the displays they can use the same capability to make large area sensors so this is really interesting so there's there's several ways to do fingerprint behind the OLED right yeah some other way from other company what is that the difference is this sensor is fabricated by TFT technology on glass or flexible substrate without silicon so the full screen sensor could be fabricated if needed full screen yeah typically yeah typically a lot of companies that will use what we call a CMOS sensor so it's based on a CMOS silicon and this is a really expensive technology so the difference here is that by using TFT you can make larger area at the cheaper costs so this is a really big difference that's why this is such an interesting demo that they're showing here because although this is the size of the sensor right now but in the future they could scale it and make it the whole screen maybe what do you think yeah the whole screen sensor could be fabricated the center side can be adjusted according to the requirement does it change anything in terms of performance or price or something else it's low cost low cost maybe lower cost and other solution maybe yeah also what's interesting is I believe this is not the sensor is not made with amorphous silicon yeah so be always saying that the sensor instead of using the standard material like amorphous silicon they have used a different new material which do you know what can you tell us what kind of material it is or cannot maybe is from the flowers but what's interesting is that this is basically a new type of sensors made on with TFT technology and a new materials to make a large area optical sensor and in the future you could have under the display the whole display would be a fingerprint sensor so maybe one application could be like one finger open this app the other finger open the other app two finger open that app use my sister's finger open another app maybe I don't know if that's a good idea for an application maybe and how's accuracy is it good enough for the FBI yeah so they said this is 500 FBI resolution right that means everybody will be able to use it like you could use it for it could be like one of these things where you the immigration but it could also be the phone yes so this will have very similar level of resolution as the scanner you find the airport because it's found at PPI and you can see you could scan the whole the whole all your fingerprints with a large area sensor like this is it possible to fake a finger like you take a copy of a finger and put it on or is there is a way to make sure that it's a real finger we have anti-fake yeah algorithm maybe something right so the thing with optical sensors it's a lot more difficult to fake the fingerprint because with capacity some people have already succeeded right with even have your iPhone you just take it like a photocop or no another you do it like in a copy you can make a copy of your of your fingerprint with capacity but with optical you need a really high-resolution image and so this is also probably more secure than traditional capacitive senses is there some kind of way that maybe the AI and the chip on the smartphone or something can like kind of like see that the finger is real and moving and maybe they can even measure like a heartbeat or something I don't know about it but maybe not so how soon is this available I can't tell it's here right yeah maybe maybe soon the technology is ready then but it only works with OLED yeah it cannot work with other stuff now city is not not possible because you need to have a light behind or something yeah so the light comes through and then then it works yeah right so yeah is the sensor made on plastic or is it made on glass I'm glass or flexible suppressors you can do both yeah yeah so now OLED is made on a lot of OLED is made on plastic so it's flexible OLED and then the this sensor if it's also made on plastic you could easily match with the flexible display and and put the two together so that's really interesting as well and nobody else have this only b.o.e just trying okay okay cool okay thank you very much
