Abstract
A backlight circuit includes a lamp panel and a plurality of electron microscope assemblies. The lamp panel includes a driving substrate and a plurality of light-emitting chips on one side of the driving substrate. The electron microscope assemblies are disposed on first sides, away from the driving substrate, of the light-emitting chips in a one-to-one correspondence manner. Each electron microscope assembly includes a transparent electrode shield, an electrolyte, and an electrode plate. The transparent electrode shields are disposed on a first side of the driving substrate. The light-emitting chips are positioned in the transparent electrode shields. The electrode plates are disposed on first sides, away from the driving substrate, of the transparent electrode shields. The electrolytes are filled between the transparent electrode shields and the electrode plates.
