Can the TFT elements and hence the pixels in an LCD display be made in the nanometer range? Say 10nm x 10nm?

  • \$\begingroup\$ What is the use of 10 nm pixels for light with a wavelength between 400 and 800 nm? \$\endgroup\$ – Uwe Jul 25 '18 at 11:05
  • \$\begingroup\$ why are you asking? .... what are your thoughts about this? \$\endgroup\$ – jsotola Jul 25 '18 at 18:07
  • \$\begingroup\$ The 10nm x 10nm is approximate size of the TFT elements but not for the sole purpose of transmitting light. In fact the elements might as large as 100nm x 100nm. I'm just throwing out small values to indicate the TFT will be small. I'm more concerned with having a low size (high resolution) of LCD elements to manipulate. And if, and it's a BIG "if", many 10nm x 10nm elements in concert are working together they could be used form structures with the LCDs other than those used for the standard (large) RGB pixels. \$\endgroup\$ – Aneikei Jul 26 '18 at 0:28

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.
