Problems solved by technology

The black level of the display can be further increased by reducing the reflection, and the use of flat glass with low light transmittance can increase the contrast of the displayed image, but it also weakens the high brightness of the displayed image
In this regard, there is no effective solution in carbon nanotube flat panel display devices.
