Can the TFT elements and hence the pixels in an LCD display be made in the nanometer range? Say 10nm x 10nm?
TFTs features are made by repetitions of a coat,photoresist,etch process using ordinary ultraviolet light same as PCB manufacture.
Even X-ray photo-lithography is challenging at 10nm (Intel makes chips with 14nm features. that's feature size, actual transistors will be several times larger.
