Scan electrical components Germany Scan model Scan price

Scan electrical component is an active-matrix liquid crystal display driven by thin-film transistors. It primarily uses current to stimulate liquid crystal molecules to generate points, lines, and planes, which combine with backlights to form images. IPS, TFT, and SLCD are all subclasses of LCD. Its working principle is that, under the action of an electric field, the alignment direction of liquid crystal molecules changes, altering the transmittance (modulation) of external light sources to complete electro-optical conversion. Then, using different excitations of the R, G, and B primary color signals, and passing through red, green, and blue primary color filter films, it completes the time-domain and spatial-domain
