Description

technical field [0001] The invention relates to the display field, in particular to a display panel and a preparation method thereof. Background technique [0002] Carbon quantum dot material is a kind of semiconductor material that can be processed by solution. It has the characteristics of easy processing and low cost. In recent years, it has been highly valued by researchers and has excellent performance in the field of luminescence. At the same time, carbon quantum dot materials have the advantages similar to quantum dot materials, such as adjustable emission wavelength, narrow emission spectrum and no heavy metal elements. They also have great potential in the fields of electroluminescence and display. [0003] The current methods of making thin films include sputtering, evaporation, silk screen printing, spin coating, scraping coating, dip coating, pulling and inkjet printing, among which the cost of sputtering and evaporation is high; the thickness and precision of si...
