IPS, TFT, and SLCD are all subcategories of LCD. Under the action of the electric field, the arrangement direction of the liquid crystal molecules changes, so that the transmittance of the external light source changes (modulation), and the electro-optical conversion is completed. Then, the different excitations of the three primary color signals of R, G, and B are used to complete the color reproduction in the time domain and space domain through the three primary color filters of red, green, and blue, providing users with a comfortable visual experience and enriching the internal functions of the mobile phone.
