Mobile displays use liquid crystal displays (LCDs). Such displays have various problems, such as narrow color gamut and color saturation. We propose an algorithm to solve these problems by using data processing without panel replacement. In general, the subtle problems in color adjustment are skin color conversion and color saturation. The human skin tone is the color that is typically remembered; viewers feel awkward when skin colors are converted to unnatural colors. This paper proposes as a solution a skin protection algorithm that detects human skin colors and protects skin colors from changing. It also introduces adaptive quadratic curves that reproduce natural appearances more vividly without color saturation. In addition, the system does not use field-to-field processing but pixel-to-pixel processing in real time so that the incoming image can be displayed without field flickering
