shell electrical components are active-matrix liquid crystal displays driven by thin-film transistors. They primarily use 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. Their operating principle is that, under the influence of an electric field, the alignment of liquid crystal molecules changes, altering the transmittance (modulation) of external light sources to achieve electro-optical conversion. Then, using different excitations of the R, G, and B primary color signals through red, green, and blue primary color filter films, temporal and spatial domains are completed.
